The **Ledger queries**, **Private data**, and **State-based endorsement** +samples demonstrate these additional capabilities. Finally, the **Secured agreement** sample demonstrates how to bring all the capabilities together to securely +transfer an asset in a more realistic transfer scenario. + +| **Smart Contract** | **Description** | **Tutorial** | **Smart contract languages** | **Application languages** | +| -----------|------------------------------|----------|---------|---------| +| [Basic](asset-transfer-basic) | The Basic sample smart contract that allows you to create and transfer an asset by putting data on the ledger and retrieving it.

The sample also uses authorization based on individual client identities to allow the users that interact with the network to own assets on the blockchain ledger. + +Attribute-Based Access Control (ABAC) refers to the ability to restrict access to certain functionality within a smart contract based on the attributes within a users certificate. For example, you may want certain functions within a smart contract to be used only by application administrators. ABAC allows organizations to provide elevated access to certain users without requiring those users be administrators of the network. For more information, see [Attribute-based access control](https://hyperledger-fabric-ca.readthedocs.io/en/latest/users-guide.html#attribute-based-access-control) in the Fabric CA users guide. + +The `asset-transfer-abac` smart contract allows you to create assets that can be updated or transferred by the asset owner. However, the ability to create or remove assets from the ledger is restricted to identities with the `abac.creator=true` attribute. The identity that creates the asset is assigned as the asset owner. Only the owner can transfer the asset to a new owner or update the asset properties. In the course of the tutorial, we will use the Fabric CA client to create identities with the attribute required to create a new asset. We will then transfer the asset to another identity and demonstrate how the `GetID()` function can be used to enforce asset ownership. We will then use the owner identity to delete the asset. Both Attribute based access control and the `GetID()` function are provided by the [Client Identity Chaincode Library](https://github.com/hyperledger/fabric-chaincode-go/blob/master/pkg/cid/README.md). + +## Start the network and deploy the smart contract + +We can use the Fabric test network to deploy and interact with the `asset-transfer-abac` smart contract. Run the following command to change into the test network directory and bring down any running nodes: +``` +cd fabric-samples/test-network +./network.sh down +``` + +Run the following command to deploy the test network using Certificate Authorities: +``` +./network.sh up createChannel -ca +``` + +You can then use the test network script to deploy the `asset-transfer-abac` smart contract to a channel on the network: +``` +./network.sh deployCC -ccn abac -ccp ../asset-transfer-abac/chaincode-go/ -ccl go +``` + +## Register identities with attributes + +We can use the one of the test network Certificate Authorities to register and enroll identities with the attribute of `abac.creator=true`. First, we need to set the following environment variables in order to use the Fabric CA client. +``` +export PATH=${PWD}/../bin:${PWD}:$PATH +export FABRIC_CFG_PATH=$PWD/../config/ +``` + +We will create the identities using the Org1 CA. Set the Fabric CA client home to the MSP of the Org1 CA admin: +``` +export FABRIC_CA_CLIENT_HOME=${PWD}/organizations/peerOrganizations/org1.example.com/ +``` + +There are two ways to generate certificates with attributes added. We will use both methods and create two identities in the process. The first method is to specify that the attribute be added to the certificate by default when the identity is registered. The following command will register an identity named creator1 with the attribute of `abac.creator=true`. + +``` +fabric-ca-client register --id.name creator1 --id.secret creator1pw --id.type client --id.affiliation org1 --id.attrs 'abac.creator=true:ecert' --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem +``` + +The `ecert` suffix adds the attribute to the certificate automatically when the identity is enrolled. As a result, the following enroll command will contain the attribute that was provided in the registration command. + +``` +fabric-ca-client enroll -u https://creator1:creator1pw@localhost:7054 --caname ca-org1 -M ${PWD}/organizations/peerOrganizations/org1.example.com/users/creator1@org1.example.com/msp --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem +``` + +Now that we have enrolled the identity, run the command below to copy the Node OU configuration file into the creator1 MSP folder. +``` +cp ${PWD}/organizations/peerOrganizations/org1.example.com/msp/config.yaml ${PWD}/organizations/peerOrganizations/org1.example.com/users/creator1@org1.example.com/msp/config.yaml +``` + +The second method is to request that the attribute be added upon enrollment. The following command will register an identity named creator2 with the same `abac.creator` attribute. +``` +fabric-ca-client register --id.name creator2 --id.secret creator2pw --id.type client --id.affiliation org1 --id.attrs 'abac.creator=true:' --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem +``` + +The following enroll command will add the attribute to the certificate: + +``` +fabric-ca-client enroll -u https://creator2:creator2pw@localhost:7054 --caname ca-org1 --enrollment.attrs "abac.creator" -M ${PWD}/organizations/peerOrganizations/org1.example.com/users/creator2@org1.example.com/msp --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem +``` + +Run the command below to copy the Node OU configuration file into the creator2 MSP folder. +``` +cp ${PWD}/organizations/peerOrganizations/org1.example.com/msp/config.yaml ${PWD}/organizations/peerOrganizations/org1.example.com/users/creator2@org1.example.com/msp/config.yaml +``` + +## Create an asset + +You can use either identity with the `abac.creator=true` attribute to create an asset using the `asset-transfer-abac` smart contract.

The `GetID()` API reads the name and issuer from the certificate of the identity that submitted the transaction and assigns that identity as the asset owner: +``` +{"ID":"Asset1","color":"blue","size":20,"owner":"x509::CN=creator1,OU=client+OU=org1,O=Hyperledger,ST=North Carolina,C=US::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US","appraisedValue":100} +``` + +## Transfer the asset + +As the owner of Asset1, the creator1 identity has the ability to transfer the asset to another owner. In order to transfer the asset, the owner needs to provide the name and issuer of the new owner to the `TransferAsset` function. The `asset-transfer-abac` smart contract has a `GetSubmittingClientIdentity` function that allows users to retrieve their certificate information and provide it to the asset owner out of band (we omit this step). Issue the command below to transfer Asset1 to the user1 identity from Org1 that was created when the test network was deployed: +``` +export RECIPIENT="x509::CN=user1,OU=client,O=Hyperledger,ST=North Carolina,C=US::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US" +peer chaincode invoke $TARGET_TLS_OPTIONS -C mychannel -n abac -c '{"function":"TransferAsset","Args":["Asset1","'"$RECIPIENT"'"]}' +``` +Query the ledger to verify that the asset has a new owner: +``` +peer chaincode query -C mychannel -n abac -c '{"function":"ReadAsset","Args":["Asset1"]}' +``` +We can see that Asset1 with is now owned by User1: +``` +{"ID":"Asset1","color":"blue","size":20,"owner":"x509::CN=user1,OU=client,O=Hyperledger,ST=North Carolina,C=US::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US","appraisedValue":100} +``` + +## Update the asset + +Now that the asset has been transferred, the new owner can update the asset properties. The smart contract uses the `GetID()` API to ensure that the update is being submitted by the asset owner. To demonstrate the difference between identity and attribute based access control, lets try to update the asset using the creator1 identity first: +``` +peer chaincode invoke $TARGET_TLS_OPTIONS -C mychannel -n abac -c '{"function":"UpdateAsset","Args":["Asset1","green","20","100"]}' +``` + +Even though creator1 can create new assets, the smart contract detects that the transaction was not submitted by the identity that owns the asset, user1. The command returns the following error: +``` +Error: endorsement failure during invoke. response: status:500 message:"submitting client not authorized to update asset, does not own asset" +``` + +Run the following command to operate as the asset owner by setting the MSP path to User1: +``` +export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp +``` + +We can now update the asset. Run the following command to change the asset color from blue to green. All other aspects of the asset will remain unchanged. +``` +peer chaincode invoke $TARGET_TLS_OPTIONS -C mychannel -n abac -c '{"function":"UpdateAsset","Args":["Asset1","green","20","100"]}' +``` +Run the query command again to verify that the asset has changed color: +``` +peer chaincode query -C mychannel -n abac -c '{"function":"ReadAsset","Args":["Asset1"]}' +``` +The result will display that Asset1 is now green: +``` +{"ID":"Asset1","color":"green","size":20,"owner":"x509::CN=user1,OU=client,O=Hyperledger,ST=North Carolina,C=US::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US","appraisedValue":100} +``` + +## Delete the asset + +The owner also has the ability to delete the asset. Run the following command to remove Asset1 from the ledger: +``` +peer chaincode invoke $TARGET_TLS_OPTIONS -C mychannel -n abac -c '{"function":"DeleteAsset","Args":["Asset1"]}' +``` + +If you query the ledger once more, you will see that Asset1 no longer exists: +``` +peer chaincode query -C mychannel -n abac -c '{"function":"ReadAsset","Args":["Asset1"]}' +``` + +While we are operating as User1, we can demonstrate attribute based access control by trying to create an asset using an identity without the `abac.creator=true` attribute. Run the following command to try to create Asset1 as User1: +``` +peer chaincode invoke $TARGET_TLS_OPTIONS -C mychannel -n abac -c '{"function":"CreateAsset","Args":["Asset2","red","20","100"]}' +``` + +The smart contract will return the following error: +``` +Error: endorsement failure during invoke. response: status:500 message:"submitting client not authorized to create asset, does not have abac.creator role" +``` + +## Clean up + +When you are finished, you can run the following command to bring down the test network: +``` +./network.sh down +``` diff --git

For more information, see the [Chaincode as an external service](https://hyperledger-fabric.readthedocs.io/en/latest/cc_launcher.html) topic in the Fabric documentation. + +**Note:** each organization in a real network would need to setup and host their own instance of the external service. For simplification purpose, in this sample we use the same instance for both organizations. + +## Setting up the external builder and launcher + +External Builders and Launchers is an advanced feature that typically requires custom packaging of the peer image so that it contains all the tools your builder and launcher require. For this sample we use very simple (and crude) shell scripts that can be run directly within the default Fabric peer images. + +Open the `config/core.yaml` file at the top of the `fabric-samples` hierarchy. Note that this file comes along with the Fabric binaries, so if you don't have it, follow the [Install the Samples, Binaries and Docker Images](https://hyperledger-fabric.readthedocs.io/en/latest/install.html) instructions in the Hyperledger Fabric documentation to download the binaries and config files. + +Modify the field `externalBuilders` as the following: +``` +externalBuilders: + - path: /opt/gopath/src/github.com/hyperledger/fabric-samples/asset-transfer-basic/chaincode-external/sampleBuilder + name: external-sample-builder +``` +This configuration sets the name of the external builder as `external-sample-builder`, and the path of the builder to the scripts provided in this sample. Note that this is the path within the peer container, not your local machine. + +To set the path within the peer container, you will need to modify the container compose file to mount a couple of additional volumes. +Open the file `test-network/docker/docker-compose-test-net.yaml`, and add to the `volumes` section of both `peer0.org1.example.com` and `peer0.org2.example.com` the following two lines: + +``` + - ../..:/opt/gopath/src/github.com/hyperledger/fabric-samples + - ../../config/core.yaml:/etc/hyperledger/fabric/core.yaml +``` + +This will mount the fabric-sample builder into the peer container so that it can be found at the location specified in the config file, +and override the peer's core.yaml config file within the fabric-peer image so that the config file modified above is used. + +## Packaging and installing Chaincode + +The Asset-Transfer-Basic external chaincode requires two environment variables to run, `CHAINCODE_SERVER_ADDRESS` and `CHAINCODE_ID`, which are described and set in the `chaincode.env` file. + +The peer needs a corresponding `connection.json` configuration file so that it can connect to the external Asset-Transfer-Basic service. + +The address specified in the `connection.json` must correspond to the `CHAINCODE_SERVER_ADDRESS` value in `chaincode.env`, which is `asset-transfer-basic.org1.example.com:9999` in our example. + +Because we will run our chaincode as an external service, the chaincode itself does not need to be included in the chaincode +package that gets installed to each peer. Only the configuration and metadata information needs to be included +in the package. Since the packaging is trivial, we can manually create the chaincode package. + +First, create a `code.tar.gz` archive containing the `connection.json` file: + +``` +tar cfz code.tar.gz connection.json +``` + +Then, create the chaincode package, including the `code.tar.gz` file and the supplied `metadata.json` file: + +``` +tar cfz asset-transfer-basic-external.tgz metadata.json code.tar.gz +``` + +You are now ready to use the external chaincode. We will use the `test-network` sample to get a network setup and make use of it. + +## Starting the test network + +In a different terminal, from the `test-network` sample directory starts the network using the following command: + +``` +./network.sh up createChannel -c mychannel -ca +``` + +This starts the test network and creates the channel. We will now proceed to installing our external chaincode package. + +## Installing the external chaincode + +We can't use the `test-network/network.sh` script to install our external chaincode so we will have to do a bit more work by hand but we can still leverage part of the test-network scripts to make this easier. + +First, get the functions to setup your environment as needed by running the following command (this assumes you are still in the `test-network` directory): + +``` +. ./scripts/envVar.sh +``` + +Install the `asset-transfer-basic-external.tar.gz` chaincode on org1: + +``` +setGlobals 1 +../bin/peer lifecycle chaincode install ../asset-transfer-basic/chaincode-external/asset-transfer-basic-external.tgz +``` + +setGlobals simply defines a bunch of environment variables suitable to act as one organization or another, org1 or org2. + +Install it on org2: + +``` +setGlobals 2 +../bin/peer lifecycle chaincode install ../asset-transfer-basic/chaincode-external/asset-transfer-basic-external.tgz +``` + +This will output the chaincode pakage identifier such as `basic_1.0:0262396ccaffaa2174bc09f750f742319c4f14d60b16334d2c8921b6842c090c` that you will need to use in the following commands. + +For convenience it is best to store your package id value in an environment variable so that it can be referenced in later commands: + +``` +export PKGID=basic_1.0:0262396ccaffaa2174bc09f750f742319c4f14d60b16334d2c8921b6842c090 +``` + +If needed, you can query the installed chaincode to get its package-id: + +``` +setGlobals 1 +../bin/peer lifecycle chaincode queryinstalled --peerAddresses localhost:7051 --tlsRootCertFiles organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt +``` + +Edit the `chaincode.env` file in the `fabric-samples/asset-transfer-basic/chaincode-external` directory as necessary to set the `CHAINCODE_ID` variable to the chaincode package-id obtained above. + + +## Running the Asset-Transfer-Basic external service + +To run the service in a container, from a different terminal, build an Asset-Transfer-Basic docker image, using the supplied `Dockerfile`, using the following command in the `fabric-samples/asset-transfer-basic/chaincode-external` directory: + +``` +docker build -t hyperledger/asset-transfer-basic . +``` + +Then, start the Asset-Transfer-Basic service: + +``` +docker run -it --rm --name asset-transfer-basic.org1.example.com --hostname asset-transfer-basic.org1.example.com --env-file chaincode.env --network=net_test hyperledger/asset-transfer-basic +``` + +This will start the container and start the external chaincode service within it. + +## Finish deploying the Asset-Transfer-Basic external chaincode + +Finishing the deployment of the chaincode on the test network can be done from the terminal you started the network from with the following commands (make sure the package-id is set to the value you received above): + +``` +setGlobals 2 +../bin/peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile $PWD/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --channelID mychannel --name basic --version 1.0 --package-id $PKGID --sequence 1 + +setGlobals 1 +../bin/peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile $PWD/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --channelID mychannel --name basic --version 1.0 --package-id $PKGID --sequence 1 + +../bin/peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile $PWD/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --channelID mychannel --name basic --peerAddresses localhost:7051 --tlsRootCertFiles $PWD/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt --version 1.0 --sequence 1 +``` + +This approves the chaincode definition for both orgs and commits it using org1. This should result in an output similar to: + +``` +2020-08-05 15:41:44.982 PDT [chaincodeCmd] ClientWait -> INFO 001 txid [6bdbe040b99a45cc90a23ec21f02ea5da7be8b70590eb04ff3323ef77fdedfc7] committed

Fabric peers endorse transactions by executing a smart contract using the +inputs of the transaction proposal. The peers then sign the input and output +generated by the smart contract execution. The endorsement policy specifies the +set of organizations whose peers need to endorse a transaction before it can be +added to the ledger. + +Each chaincode that is deployed to a channel has an endorsement policy that governs +the assets managed by the chaincode smart contracts. However, you can override the +chaincode level endorsement policy to create an endorsement policy for a specific key, +either on the public channel ledger or in a private collection. +State-based endorsement policies, also known as key-level endorsement policies, allow +channel members to use different endorsement policies for assets that are managed by +the same smart contract. For more information about endorsement policies and +state-based endorsement, visit the +[Endorsement Policies](https://hyperledger-fabric.readthedocs.io/en/release-2.2/endorsement-policies.html) +topic in the Fabric documentation. + +The implementation provided by State Based interface creates a policy which requires signatures from all the Org principals added, and hence is equivalent to an AND policy. For other advanced State Based policy implementations which are not supported by State Based interface directly like OR or NOutOf policies, please refer to method implementations setStateBasedEndorsementNOutOf(), which can be used as an alternative for setStateBasedEndorsement() inside asset-transfer-sbe smart contracts. + +## About the Sample + +The state-based endorsement (SBE) asset transfer sample demonstrates how to use +key-level endorsement policies to ensure that an asset only is endorsed by an +asset owner. In the course of the tutorial, you will use the smart contract +to complete the following transfer scenario: + +- Deploy the SBE smart contract to a channel that was created using the Fabric +test network. The channel will have two members, Org1 and Org2, that will +participate in the asset transfer. Each organization operates one peer that +is joined to the channel. +- Create an asset using the chaincode endorsement policy. The chaincode level +endorsement policy requires that a majority of organizations on the channel +endorse a transaction. This means that a transaction that creates an asset +needs to be endorsed by peers that belong to Org1 and Org2. When the asset is +created, the smart contract creates a state-based endorsement policy that +specifies that only the organization that owns that asset may endorse update +transactions. Because the asset is owned by Org1, any future updates to the asset +need to be endorsed by the Org1 peer. +- Update the asset by only endorsing with Org1, this will use the state-based +endorsement policy applied to the asset when it was created by the chaincode. +- Transfer the asset to Org2. During the execution of the transfer transaction, +the chaincode will create a new state-based endorsement policy that reflects +the new asset owner for the asset. +- Update the asset once more, this time with Org2 as the owner. Because the +state-based endorsement policy has been updated, this transaction only needs +to be endorsed by Org2. + +## Deploy the smart contract + +We are going to run the SBE smart contract using the Fabric test network. Open a command terminal and navigate to test network directory in your local clone of the `fabric-samples`. We will operate from the `test-network` directory for the remainder of the tutorial. +``` +cd fabric-samples/test-network +``` + +Run the following command to deploy the test network and create a channel named `mychannel`: + +``` +./network.sh up createChannel +``` + +You can use the test network script to deploy the smart contract to the channel that was just created. The script uses the Fabric chaincode lifecycle to deploy the smart contract to the channel. We will use the default chaincode level endorsement policy used by the Fabric chaincode lifecycle, which requires an endorsement from a majority of channel members. In our case, this will require that both Org1 and Org2 endorse a transaction (2 of 2). Deploy the smart contract to `mychannel` using the following command: +``` +./network.sh deployCC -ccn sbe -ccp ../asset-transfer-sbe/chaincode-typescript/ -ccl typescript +``` + +Set the following environment variables to interact with the network as a user from Org1: + +``` +export PATH=${PWD}/../bin:${PWD}:$PATH +export FABRIC_CFG_PATH=$PWD/../config/ +export CORE_PEER_TLS_ENABLED=true +export CORE_PEER_LOCALMSPID="Org1MSP" +export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp +export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt +export CORE_PEER_ADDRESS=localhost:7051 +``` + +## Run the transfer scenario + +We can now invoke the SBE smart contract to create a new asset: +``` +peer chaincode invoke -o localhost:7050 --waitForEvent --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n sbe --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"CreateAsset","Args":["asset1","100","Org1User1"]}' +``` +The create transaction needs to target both peers from Org1 and Org2 to meet the chaincode endorsement policy. The chaincode will read the MSP ID of the client user submitting the transaction and assign that organization as the asset owner. As a result, the asset will initially be owned by Org1. + +You can query the asset using with the following command: +``` +peer chaincode query -C mychannel -n sbe -c '{"Args":["ReadAsset","asset1"]}' +``` +The result is a new asset owned by Org1, identified using the Org1 MSP ID `Org1MSP`: +`{"ID":"asset1","Value":100,"Owner":"Org1User1","OwnerOrg":"Org1MSP"}` + +In addition to creating the asset, the `CreateAsset` function also sets a state-based endorsement policy for the asset. Only a peer of the asset owner, can successfully endorse an asset update. To demonstrate the key-level endorsement policy, lets try to update the asset while targeting the Org2 peer: +``` +peer chaincode invoke -o localhost:7050 --waitForEvent --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n sbe --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"UpdateAsset","Args":["asset1","200"]}' +``` +The result is an endorsement policy failure: +``` +Error: transaction invalidated with status (ENDORSEMENT_POLICY_FAILURE) - proposal response: +``` + +If we attempt to update the asset with an endorsement from the Org1 peer, the update succeeds: +``` +peer chaincode invoke -o localhost:7050 --waitForEvent --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n sbe --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt -c '{"function":"UpdateAsset","Args":["asset1","200"]}' +``` +You can query the asset one more time to verify that the update was successful: +``` +peer chaincode query -C mychannel -n sbe -c '{"Args":["ReadAsset","asset1"]}' +``` + +The asset value is now 200: +``` +{"ID":"asset1","Value":200,"Owner":"Org1User1","OwnerOrg":"Org1MSP"} +``` + +Now that we have tested the asset key-level endorsement policy, we can transfer the asset to Org2. Run the following command to transfer the asset from Org1 to Org2. This time the Org2 MSP ID is provided as a transaction input. The `TransferAsset` function will update the endorsement policy to specify that only a peer of the new owner can update the asset.

The transfer enabled by the SBE smart contract is a simple scenario meant only to demonstrate the use of state-based endorsement policies. The smart contract can use access control to specify that an asset can only be updated by its owner. Private data collections can also be used to ensure that transfers need to be endorsed by the owner and recipient of the transfer, instead of just the asset owner. For a more realistic example of an asset transfer scenario, see the [Secured asset transfer in Fabric](https://hyperledger-fabric.readthedocs.io/en/master/secured_asset_transfer/secured_private_asset_transfer_tutorial.html) tutorial. + +## Clean up + +When you are finished, you can bring down the test network.

+++ b/auction/README.md @@ -0,0 +1,416 @@ +## Simple blind auction sample + +The simple blind auction sample uses Hyperledger Fabric to run an auction where bids are kept private until the auction period is over. Instead of displaying the full bid on the public ledger, buyers can only see hashes of other bids while bidding is underway. This prevents buyers from changing their bids in response to bids submitted by others. After the bidding period ends, participants reveal their bid to try to win the auction. The organizations participating in the auction verify that a revealed bid matches the hash on the public ledger. Whichever has the highest bid wins. + +A user that wants to sell one item can use the smart contract to create an auction. The auction is stored on the channel ledger and can be read by all channel members. The auctions created by the smart contract are run in three steps: +1. Each auction is created with the status **open**. While the auction is open, buyers can add new bids to the auction. The full bids of each buyer are stored in the implicit private data collections of their organization. After the bid is created, the bidder can submit the hash of the bid to the auction. A bid is added to the auction in two steps because the transaction that creates the bid only needs to be endorsed by a peer of the bidders organization, while a transaction that updates the auction may need to be endorsed by multiple organizations. When the bid is added to the auction, the bidder's organization is added to the list of organizations that need to endorse any updates to the auction. +2. The auction is **closed** to prevent additional bids from being added to the auction. After the auction is closed, bidders that submitted bids to the auction can reveal their full bid. Only revealed bids can win the auction. +3. The auction is **ended** to calculate the winner from the set of revealed bids. All organizations participating in the auction calculate the price that clears the auction and the winning bid. The seller can end the auction only if all bidding organizations endorse the same winner and price. + +Before endorsing the transaction that ends the auction, each organization queries the implicit private data collection on their peers to check if any organization member has a winning bid that has not yet been revealed. If a winning bid is found, the organization will withhold their endorsement and prevent the auction from being closed. This prevents the seller from ending the auction prematurely, or colluding with buyers to end the auction at an artificially low price. + +The sample uses several Fabric features to make the auction private and secure. Bids are stored in private data collections to prevent bids from being distributed to other peers in the channel. When bidding is closed, the auction smart contract uses the `GetPrivateDataHash()` API to verify that the bid stored in private data is the same bid that is being revealed. State based endorsement is used to add the organization of each bidder to the auction endorsement policy. The smart contract uses the `GetClientIdentity.GetID()` API to ensure that only the potential buyer can read their bid from private state and only the seller can close or end the auction. + +This tutorial uses the auction smart contract in a scenario where one seller wants to auction a painting. Four potential buyers from two different organizations will submit bids to the auction and try to win the auction. + +## Deploy the chaincode + +We will run the auction smart contract using the Fabric test network. Open a command terminal and navigate to the test network directory: +``` +cd fabric-samples/test-network +``` + +You can then run the following command to deploy the test network. +``` +./network.sh up createChannel -ca +``` + +Note that we use the `-ca` flag to deploy the network using certificate authorities. We will use the CA to register and enroll our sellers and buyers. + +Run the following command to deploy the auction smart contract. We will override the default endorsement policy to allow any channel member to create an auction without requiring an endorsement from another organization. +``` +./network.sh deployCC -ccn auction -ccp ../auction/chaincode-go/ -ccl go -ccep "OR('Org1MSP.peer','Org2MSP.peer')" +``` + +## Install the application dependencies + +We will interact with the auction smart contract through a set of Node.js applications. Change into the `application-javascript` directory: +``` +cd fabric-samples/auction/application-javascript +``` + +From this directory, run the following command to download the application dependencies: +``` +npm install +``` + +## Register and enroll the application identities + +To interact with the network, you will need to enroll the Certificate Authority administrators of Org1 and Org2. You can use the `enrollAdmin.js` program for this task. Run the following command to enroll the Org1 admin: +``` +node enrollAdmin.js org1 +``` +You should see the logs of the admin wallet being created on your local file system. Now run the command to enroll the CA admin of Org2: +``` +node enrollAdmin.js org2 +``` + +We can use the CA admins of both organizations to register and enroll the identities of the seller that will create the auction and the bidders who will try to purchase the painting. + +Run the following command to register and enroll the seller identity that will create the auction. The seller will belong to Org1. +``` +node registerEnrollUser.js org1 seller +``` + +You should see the logs of the seller wallet being created as well.

Run the following command to use the seller wallet to run the `createAuction.js` application. The program will submit a transaction to the network that creates the auction on the channel ledger. The organization and identity name are passed to the application to use the wallet that was created by the `registerEnrollUser.js` application. The seller needs to provide an ID for the auction and the item to be sold to create the auction: +``` +node createAuction.js org1 seller PaintingAuction painting +``` + +After the transaction is complete, the `createAuction.js` application will query the auction stored in the public channel ledger: +``` +*** Result: Auction: { + "objectType": "auction", + "item": "painting", + "seller": "eDUwOTo6Q049c2VsbGVyLE9VPWNsaWVudCtPVT1vcmcxK09VPWRlcGFydG1lbnQxOjpDTj1jYS5vcmcxLmV4YW1wbGUuY29tLE89b3JnMS5leGFtcGxlLmNvbSxMPUR1cmhhbSxTVD1Ob3J0aCBDYXJvbGluYSxDPVVT", + "organizations": [ + "Org1MSP" + ], + "privateBids": {}, + "revealedBids": {}, + "winner": "", + "price": 0, + "status": "open" +} +``` +The smart contract uses the `GetClientIdentity().GetID()` API to read identity that creates the auction and defines that identity as the auction `"seller"`.

+ +This folder contains a structured set of smart contracts and application clients (ie. in a choice of languages, eg Node.js, Java, Go etc) relating to *Commercial Paper*, a finance 'instrument' (in Global Finance). At present, the Node.js sample contract in particular has further added functionality: an optional two-step authority check (see diagram below), when redeeming a commercial paper instance - and a range of sample ledger queries, to help consolidate your learning; both can be explored using the Node.js application client. + +While a more detailed 'explainer' of the Commercial Paper scenario (including use case analysis, code walkthrough & practices, logical/physical representation of ledger data etc) can be found in the [Hyperledger Fabric Commercial Paper Tutorial](https://hyperledger-fabric.readthedocs.io/en/latest/tutorial/commercial_paper.html), you don't have to read through this, just to try out this sample. There's also a [Wikipedia page](https://en.wikipedia.org/wiki/Commercial_paper) + +

Key Objectives + + * see a Commercial Paper use case in action + + * explore the key 'takeaways': understand differences between asset _state_ changes ('e.g. 'lifecycle') and transaction _inputs_* (e.g. 'inputs' during lifecycle) + + * try out a number of different query types: asset history, asset state, ownership, partial key, named query (criteria-based), ad-hoc queries (you supply a query string) - presently available in the Node.js sample only. + + \* the smart contract uses these (along with business logic) to decide outcomes; some inputs change the asset _state_ (like 'ownership') ; some don't. + +

+
+ +

+
+ +But first, it might useful to explain Commercial Paper, an unsecured promissory note issued to obtain capital, and operates in global financial markets. A Commercial Paper instance is represented as an asset with a lifecycle, recorded on the blockchain - transactions change its _state_ (over time) and those transactions, naturally - have _inputs_. + + +#### Explainers + +
Commercial Paper - what is it briefly? + +
+It is a type of unsecured promissory note, issued by established companies (eg big manufacturers, blue chip corporations) to gain short-term capital - usually no more than 6-9 months. Why? To meet short-term financial obligations. Commercial paper is generally purchased by money market funds and banks - in fact, it becomes a more important investment strategy during financial recessions :-) . A corporation issues a paper (in the form of a promissory note) for specific projects, such as big capital investments, to pay contractors or even to exercise debt restructuring. The tutorial describes MagnetoCorp (car manufacturer) who have landed a huge contract, and will need approx. $5m in capital (payroll obligations), to hire 1000 car workers for at least 6 months (with no car revenues yet - its a financial strain). Underpinning this, of course, is that MagnetoCorp, has every confidence that (say, in 6 months time) it will be in a position to pay out the face value ($5m in this case) when the commercial paper is redeemd by an owner of the paper, upon maturity :-). +

+
+ +
Ins and Outs, Attractions of Commercial Paper Investment? + +
+Investors (who buy Commercial Paper) are attracted as they agree to buy them at a discount (say $4.94m) on the face value (eg $5m) and moreso, they obtain a higher yield than if they were simply gaining interest in a bank (eg. 2% interest on $4.95m today = $5m in 6 months time). But there is a 'premium' attached, with carrying the risk of a debt/loan that is essentially unsecured (unlike a bank) - which is where credit risk and ratings comes in. As a result, the actual yield from the investment chosen is in effect $10k greater (than pure interest, in the example given). +

+Once an issuing corporation becomes established in the commercial paper marketplace, it builds a high credit rating (risk affects how much of a premium investors seek and therefore discount accordingly) - in fact, it is often cheaper (for a blue chip company) to draw on a commercial paper than on a bank line of credit. But that rating reflects the issuer's ability to pay back on maturity. +

+I mentioned marketplace: even during the typical 6-9 month period, a commercial paper can be bought and sold multiple times (its quoted, at the discounted price on money markets), before the Commercial Paper reaches its maturity date. On that date, the current investor (or owner) 'redeems' the paper bond with MagnetoCorp, the issuer and gets the face value of $5m. + +
+ +[_back to top_](#top) + +## Scenario Overview + +![](https://hyperledger-fabric.readthedocs.io/en/latest/_images/commercial_paper.diagram.1.png) + +In this tutorial two organizations, MagnetoCorp and DigiBank, trade commercial paper with each other on 'PaperNet', the marketplace represented by a Hyperledger Fabric blockchain network. Note that there are two alternative transaction flows - one which mirrors the [Commercial Paper Tutorial](https://hyperledger-fabric.readthedocs.io/en/latest/tutorial/commercial_paper.html) as described in Fabric documentation, and one which requires the authorised owner of the paper to complete a transfer following a request to buy the commercial paper - the latter example features an authorization check in the smart contract that ensures the transactor is from the organization that currently owns the commercial paper - they approve and complete the buy request. These are the commercial paper transaction lifecycles you can try out: + +![Transaction Flow alternatives](img/transaction-flow.png) + +The tutorial exercises the commercial paper asset lifecycle: _issue_, _buy_ ( 1 to _n_ ) (or _buy_request_ / _transfer_ alternative), and _redeem_ transactions: the key 'takeaways' from the scenario are: + +- understanding the _changes in state_ in the commercial paper asset (reflected in the ledger world state) which reaches maturity after 6 months. +- understanding the _transaction inputs_ for each transaction (some inputs change the asset _state_ - eg. ownership) and some _don't_ (e.g. purchase price) and not part of the asset - but importantly, the _inputs_ for a given transaction are recorded on the blockchain). +- understanding the importance of _queries_ such as: asset history, rich queries (criteria matching etc), transaction history (where the inputs are recorded) + +Client applications (CLI based) are used: + +- to perform the transactions +- run queries (Node.js sample only) +- examine the transaction inputs (as opposed to _states_) that are written to the ledger after you perform a transaction (using the Node.js listener). + +This sample uses the `test-network` . You’ll act as Isabella, an employee of MagnetoCorp (Org2), who will issue a commercial paper on its behalf. You’ll then 'switch hats' to take the role of Balaji, an employee of DigiBank (Org1), who will buy this commercial paper, hold it for a period of time, and then redeem it with MagnetoCorp for a small profit or yield. Note that the smart contract sample doesn't enforce the actual hold period ; the user can, in fact, redeem the paper immediately. + + +## Quick Start + +Below are the quick start instructions for running the tutorial. As mentioned, if you're interested in a 'deeper dive' analysis and importance of the concepts, design, structure and implementation of the smart contract, they can be found in the [Hyperledger Fabric Commercial Paper Tutorial](https://hyperledger-fabric.readthedocs.io/en/latest/tutorial/commercial_paper.html). Suffice to say, you DON'T have to have read this, to do this tutorial. + +This `README.md` file is in the `commercial-paper` directory, the source code for client applications and the contracts is in the `organization` directory. + +### High-Level Overview of Steps + +1) Install Binaries, Start the Hyperledger Fabric infrastructure + + The Fabric 'test-network' will be used - this has two organizations 'Org1' and 'Org2' DigiBank will be Org1, and MagnetoCorp will be Org2. + +2) Install and Instantiate the Contracts + +3) Run client applications in the roles of MagnetoCorp and DigiBank to trade the commercial paper + + - Issue the Paper as Magnetocorp (org2) + - Buy the paper as DigiBank (org1) + - Redeem the paper as DigiBank (org1) + + See also the transaction flow and alternatives in the Scenario Overview below. + +[_back to top_](#top) + +## Setup + +You will need a machine with the following + +- Docker and docker-compose installed +- Node.js v12 if you want to run JavaScript client applications +- Java v8 if you want to run Java client applications +- Maven to build the Java applications + +You will need to install the `peer` cli binaries and cloned the `fabric-samples` repository. For more information see +[Install the Samples, Binaries and Docker Images](https://hyperledger-fabric.readthedocs.io/en/latest/install.html) in the Hyperledger Fabric documentation. Once you have installed the cli binaries, ensure you have added the `bin` directory (for your `peer` commands used by scripts below) to your exported `PATH` variable in your `.bashrc` or `.profile` directory (per below). This is important as you will be opening a number of windows which will need PATH set. Finally, check that it finds the `peer` command in your PATH using the `which` command eg. + +``` +export PATH=:$PATH +which peer +``` + + +It is advised to have 3 terminal windows (consoles) open; + +* one to monitor the infrastructure +* one for MagnetoCorp +* one for DigiBank. + +Once you've cloned the `fabric-samples` - change to the `commercial-paper` directory in each window. + +``` +git clone https://github.com/hyperledger/fabric-samples.git +``` + +``` +cd fabric-samples/commercial-paper +``` + +## Running the Infrastructure + +In one console window, run the network starter script - this will start the two organization `test-network` blockchain network. + +``` +./network-starter.sh +``` + +You can re-use this console window if you wish, but it is recommended to run a docker container monitoring script in its own window. This will let you view what Fabric is doing and help diagnose any failures. + +```bash +./organization/magnetocorp/configuration/cli/monitordocker.sh net_test +``` + +### Setup the Organizations' environments + +The contract code is available as either JavaScript, Java or Go. You can use either one, and the choice of contract language does not affect the choice of client language. With the v2.0 Fabric chaincode lifecycle, this requires operations for both MagnetoCorp and Digibank admin. Open two windows in the fabric-samples/commercial paper directory, one for each organization. + +In your 'MagnetoCorp' window run the following commands, to set the shell environment variables needed to act as that organization. The leading '.' in the command sequence sets in your current environment - if you do not run this, you will not be able to package the chaincode. + +``` +cd fabric-samples/commercial-paper/organization/magnetocorp +. ./magnetocorp.sh +``` + +You can either copy and paste them directly into the terminal, or invoke directly in your own command shell. For example if you are using bash or zsh on Linux you can use this command. + +``` +source <(./magnetocorp.sh) +``` + +Similarly in your 'DigiBank' window run the following commands as shown: + +``` +cd fabric-samples/commercial-paper/organization/digibank +. ./digibank.sh +``` + +[_back to top_](#top) + + +### Deploy the smart contract to the channel + +You need to perform similar operations for _both_ organizations and for your language choice from the instructions below. For the different contract languages, the steps are very similar - the full set of steps are actually shown in the JavaScript section (see twisty). However, you will perform one or two different initial steps for Java or Go before completing the remaining common steps as instructed in those language sections. + +Note that the commands below make use of the `jq` utility for parsing output - download and install it from [the jq download page](https://stedolan.github.io/jq/download/). + + +**

+ + +[_back to top_](#top) + + +## Client Applications + +Note for Java applications, you will need to compile the Java Code using `maven`. Use this command in each application-java directory + +``` +mvn clean package +``` + +Note for JavaScript applications, you will need to install the dependencies first. Use this command in each application directory + +``` +npm install +``` +> Note that there is NO dependency between the language of any one client application and any contract. Mix and match as you wish! + +The docker containers don't contain the node or Java runtimes; so it is best to exit the docker containers - but keep the windows open and run the applications locally. + +As mentioned earlier in the Sample introduction section, transaction _inputs_ are recorded on the ledger, as well as any asset _state_ changes. Just *before* you run the _issue_ application script below - you need to launch a block 'listener' application that will show you these _inputs_, as you complete each transaction in the commercial paper lifecycle (eg. Paper Number: 00001, 00002 etc) . + +For the listener, its best to open a *new* terminal for this in the `commercial-paper/organization/magnetocorp/application` directory (javascript). Next, run the `addToWallet` step in the `issue` transaction below, to add Isabella's identity to the wallet - the listener will use this wallet. Once the listener is launched, it will show the inputs for transactions you will perform and which are committed to blocks (ie part of the ledger). Note: initially, the listener may show a spurious message, and then go into a _listening_ or 'wait' state. As transactions complete below, messages will be displayed by the listener - so keep an eye out. *After* adding Isabella's wallet, you can then launch the listener as follows: + +``` +node cpListener.js +``` + +**
Issue the commercial paper** + +The paper is issued by *MagnetoCorp* + +You can now run the applications to issue the commercial paper. Change to either the +`commercial-paper/organization/magnetocorp/application` directory (javascript) or `commercial-paper/organization/magnetocorp/application-java` directory (java) + +*Add the Identity to be used to the wallet* + +``` +node addToWallet.js +# or +java -cp target/commercial-paper-0.0.1-SNAPSHOT.jar org.magnetocorp.AddToWallet +``` + +*Issue the Commercial Paper* + +``` +node issue.js +# or +java -cp target/commercial-paper-0.0.1-SNAPSHOT.jar org.magnetocorp.Issue +``` + +Don't forget to check the application listener for messages above! + +

+
+ + +**
Buy the commercial paper** + +_Buy_ is performed as *Digibank*; + +You can now run the applications to buy the paper. Change to either the +`commercial-paper/organization/digibank/application` directory or `commercial-paper/organization/digibank/application-java` + +*Add the Identity to be used* + +``` +node addToWallet.js +# or +java -cp target/commercial-paper-0.0.1-SNAPSHOT.jar org.digibank.AddToWallet +``` + +*Buy the paper* + +``` +node buy.js +# or +java -cp target/commercial-paper-0.0.1-SNAPSHOT.jar org.digibank.Buy +``` + +If you have just executed a `buy` transaction above - jump to the `redeem` transaction below - otherwise execute the _buy_/_transfer_ sequence as described earlier. + +*Alternative: Request to Buy the paper (buy/transfer)* + +``` +node buy_request.js +``` + +Now complete the _request_ by switching to the `MagnetoCorp` application directory (javascript) and execute a `transfer` transaction as MagnetoCorp: + +``` +cd ../../magnetocorp/application + +node transfer.js +``` + +

+
+ +**
Redeem the commercial paper** + +_Redeem_ is performed as *Digibank* - the current owner (buyer) in the lifecycle. + +You can now run the applications to redeem the paper. Change to either the +`commercial-paper/organization/digibank/application` directory or `commercial-paper/organization/digibank/application-java` + + +*Redeem* + +``` +node redeem.js +# or +java -cp target/commercial-paper-0.0.1-SNAPSHOT.jar org.digibank.Redeem +``` + +

+
+ + +**
Perform Queries: Ownership, Asset History etc (Node.js sample only) ** + + Having completed the full commercial paper lifecycle for one paper (paper number: 00001) some queries below won't show a lot of data - as an optional exercise, you can change the scripts above (paper number: 00002) to create another paper lifecycle and run the `queryapp` application below (change query 1 to the new CP number FYI), with more data available. As indicated, the query transactions mentioned are presently only available in the Node.js sample. + + Execute the Node.js application client script, which will run the following 5 queries, in order: + + - History of Commercial Paper (Note: the paper state is shown more descriptively eg. 'ISSUED', 'TRADING' and based on currentState values on ledger) + - Ownership of Commercial Papers + - Partial Key query, for Commercial papers in org.papernet.papers namespace belonging to MagnetoCorp + - Named Query: all redeemed papers in a state of 'redeemed' (currentState = 4) + - Named Query: all commercial papers with a face value > $4m + + From the `digibank/application` subdirectory run: + + ``` + node queryapp.js + ``` + +

+
+ +When you're done with this section, return to the terminal where your Node.js _listener_ application is running, and terminate the process. + +## Clean up +When you are finished using the Fabric test network and the commercial paper smart contract and applications, you can use the following command to clean up the network: + +``` +./network-clean.sh +``` + +[_back to top_](#top) diff --git

A naive implementation would use a single key to represent the data for the asset, and the chaincode would +then attempt to update this key every time a transaction involving it comes in. However, when many transactions all come in at once, in the time +between when the transaction is simulated on the peer (i.e. read-set is created) and it's ready to be committed to the ledger, another transaction +may have already updated the same value. Thus, in the simple implementation, the read-set version will no longer match the version in the orderer, +and a large number of parallel transactions will fail. To solve this issue, the frequently updated value is instead stored as a series of deltas +which are aggregated when the value must be retrieved. In this way, no single row is frequently read and updated, but rather a collection of rows +is considered. + +## Use Case +The primary use case for this chaincode data model design is for applications in which a particular asset has an associated amount that is +frequently added to or removed from. For example, with a bank or credit card account, money is either paid to or paid out of it, and the amount +of money in the account is the result of all of these additions and subtractions aggregated together. A typical person's bank account may not be +used frequently enough to require highly-parallel throughput, but an organizational account used to store the money collected from customers on an +e-commerce platform may very well receive a very high number of transactions from all over the world all at once. In fact, this use case is the only +use case for crypto currencies like Bitcoin: a user's unspent transaction output (UTXO) is the result of all transactions he or she has been a part of +since joining the blockchain. Other use cases that can employ this technique might be IOT sensors which frequently update their sensed value in the +cloud. + +By adopting this method of storing data, an organization can optimize their chaincode to store and record transactions as quickly as possible and can +aggregate ledger records into one value at the time of their choosing without sacrificing transaction performance. Given the state-machine design of +Hyperledger Fabric, however, careful considerations need to be given to the data model design for the chaincode. + +Let's look at some concrete use cases and how an organization might implement high-throughput storage. These cases will try and explore some of the +advantages and disadvantages of such a system, and how to overcome them. + +#### Example 1 (IOT): Boxer Construction Analysts + +Boxer Construction Analysts is an IOT company focused on enabling real-time monitoring of large, expensive assets (machinery) on commercial +construction projects. They've partnered with the only construction vehicle company in New York, Condor Machines Inc., to provide a reliable, +auditable, and replayable monitoring system on their machines. This allows Condor to monitor their machines and address problems as soon as +they occur while providing end-users with a transparent report on machine health, which helps keep the customers satisfied. + +The vehicles are outfitted with many sensors each of which broadcasts updated values at frequencies ranging from several times a second to +several times a minute. Boxer initially sets up their chaincode so that the central machine computer pushes these values out to the blockchain +as soon as they're produced, and each sensor has its own row in the ledger which is updated when a new value comes in. While they find that +this works fine for the sensors which only update several times a minute, they run into some issues when updating the faster sensors. Often, +the blockchain skips several sensor readings before adding a new one, defeating the purpose of having a fast, always-on sensor. The issue they're +running into is that they're sending update transactions so fast that the version of the row is changed between the creation of a transaction's +read-set and committing that transaction to the ledger. The result is that while a transaction is in the process of being committed, all future +transactions are rejected until the commitment process is complete and a new, much later reading updates the ledger. + +To address this issue, they adopt a high-throughput design for the chaincode data model instead. Each sensor has a key which identifies it within the +ledger, and the difference between the previous reading and the current reading is published as a transaction. For example, if a sensor is monitoring +engine temperature, rather than sending the following list: 220F, 223F, 233F, 227F, the sensor would send: +220, +3, +10, -6 (the sensor is assumed +to start a 0 on initialization). This solves the throughput problem, as the machine can post delta transactions as fast as it wants and they will all +eventually be committed to the ledger in the order they were received. Additionally, these transactions can be processed as they appear in the ledger +by a dashboard to provide live monitoring data. The only difference the engineers have to pay attention to in this case is to make sure the sensors can +send deltas from the previous reading, rather than fixed readings. + +#### Example 2 (Balance Transfer): Robinson Credit Co. + +Robinson Credit Co. provides credit and financial services to large businesses. As such, their accounts are large, complex, and accessed by many +people at once at any time of the day. They want to switch to blockchain, but are having trouble keeping up with the number of deposits and +withdrawals happening at once on the same account. Additionally, they need to ensure users never withdraw more money than is available +on an account, and transactions that do get rejected. The first problem is easy to solve, the second is more nuanced and requires a variety of +strategies to accommodate high-throughput storage model design. + +To solve throughput, this new storage model is leveraged to allow every user performing transactions against the account to make that transaction in terms +of a delta. For example, global e-commerce company America Inc. must be able to accept thousands of transactions an hour in order to keep up with +their customer's demands. Rather than attempt to update a single row with the total amount of money in America Inc's account, Robinson Credit Co. +accepts each transaction as an additive delta to America Inc's account. At the end of the day, America Inc's accounting department can quickly +retrieve the total value in the account when the sums are aggregated. + +However, what happens when American Inc. now wants to pay its suppliers out of the same account, or a different account also on the blockchain? +Robinson Credit Co. would like to be assured that America Inc.'s accounting department can't simply overdraw their account, which is difficult to +do while at the same enabling transactions to happen quickly, as deltas are added to the ledger without any sort of bounds checking on the final +aggregate value. There are a variety of solutions which can be used in combination to address this. + +Solution 1 involves polling the aggregate value regularly. This happens separate from any delta transaction, and can be performed by a monitoring +service setup by Robinson themselves so that they can at least be guaranteed that if an overdraw does occur, they can detect it within a known +number of seconds and respond to it appropriately (e.g. by temporarily shutting off transactions on that account), all of which can be automated. +Furthermore, thanks to the decentralized nature of Fabric, this operation can be performed on a peer dedicated to this function that would not +slow down or impact the performance of peers processing customer transactions. + +Solution 2 involves breaking up the submission and verification steps of the balance transfer. Balance transfer submissions happen very quickly +and don't bother with checking overdrawing. However, a secondary process reviews each transaction sent to the chain and keeps a running total, +verifying that none of them overdraw the account, or at the very least that aggregated withdrawals vs deposits balance out at the end of the day. +Similar to Solution 1, this system would run separate from any transaction processing hardware and would not incur a performance hit on the +customer-facing chain. + +Solution 3 involves individually tailoring the smart contracts between Robinson and America Inc, leveraging the power of chaincode to customize +spending limits based on solvency proofs. Perhaps a limit is set on withdrawal transactions such that anything below \$1000 is automatically processed +and assumed to be correct and at minimal risk to either company simply due to America Inc. having proved solvency. However, withdrawals above \$1000 +must be verified before approval and admittance to the chain. + +## How +This sample provides the chaincode and scripts required to run a high-throughput application on the Fabric test network. + +### Start the network + +You can use the `startFabric.sh` script to create an instance of the Fabric test network with a single channel named `mychannel`. The script then deploys the `high-throughput` chaincode to the channel by installing it on the test network peers and committing the chaincode definition to the channel. + +Change back into the `high-throughput` directory in `fabic-samples`. Start the network and deploy the chaincode by issuing the following command: +``` +./startFabric.sh +``` + +If successful, you will see messages of the Fabric test network being created and the chaincode being deployed, followed by the execution time of the script: +``` +Total setup execution time : 81 secs ... +``` + +The `high-throughput` chaincode is now ready to receive invocations. + +### Invoke the chaincode + +You can invoke the `high-througput` chaincode using a Go application in the `application-go` folder. The Go application will allow us to submit many transactions to the network concurrently. Navigate to the application: +``` +cd application-go +``` + +#### Update +The format for update is: `go run app.go update name value operation` where `name` is the name of the variable to update, `value` is the value to add to the variable, and `operation` is either `+` or `-` depending on what type of operation you'd like to add to the variable. + +Example: `go run app.go update myvar 100 +` + +#### Query +You can query the value of a variable by running `go run app.go get name` where `name` is the name of the variable to get. + +Example: `go run app.go get myvar` + +#### Prune +Pruning takes all the deltas generated for a variable and combines them all into a single row, deleting all previous rows. This helps cleanup the ledger when many updates have been performed. + +The format for pruning is: `go run app.go prune name` where `name` is the name of the variable to prune. + +Example: `go run app.go prune myvar` + +#### Delete +The format for delete is: `go run app.go delete name` where `name` is the name of the variable to delete. + +Example: `go run app.go delete myvar` + +### Test the Network + +The application provides two methods that demonstrate the advantages of this system by submitting many concurrent transactions to the smart contract: `manyUpdates` and `manyUpdatesTraditional`. The first function accepts the same arguments as `update-invoke.sh` but runs the invocation 1000 times in parallel. The final value, therefore, should be the given update value * 1000. + +The second function, `manyUpdatesTraditional`, submits 1000 transactions that attempt to upddate the same key in the world state 1000 times. + +Run the following command to create and update `testvar1` a 1000 times: +``` +go run app.go manyUpdates testvar1 100 + +``` + +The application will query the variable after submitting the transaction.

services](https://hyperledger-fabric.readthedocs.io/en/master/peer_event_services.html) +to replicate the data on your blockchain network to an off chain database. +Using an off chain database allows you to analyze the data from your network or +build a dashboard without degrading the performance of your application. + +This sample uses the [Fabric network event listener](https://hyperledger.github.io/fabric-sdk-node/release-1.4/tutorial-channel-events.html) from the Node.JS Fabric SDK to write data to local instance of +CouchDB. + +## Getting started + +This sample uses Node Fabric SDK application code to connect to a running instance +of the Fabric test network. Make sure that you are running the following +commands from the `off_chain_data` directory. + +### Starting the Network + +Use the following command to start the sample network: + +``` +./startFabric.sh +``` + +This command will deploy an instance of the Fabric test network. The network +consists of an ordering service, two peer organizations with one peers each, and +a CA for each org. The command also creates a channel named `mychannel`. The +`asset-transfer-basic` chaincode will be installed on both peers and deployed to +the channel. + +### Configuration + +The configuration for the listener is stored in the `config.json` file: + +``` +{ + "peer_name": "peer0.org1.example.com", + "channelid": "mychannel", + "use_couchdb":true, + "create_history_log":true, + "couchdb_address": "http://localhost:5990" +} +``` + +`peer_name:` is the target peer for the listener. +`channelid:` is the channel name for block events. +`use_couchdb:` If set to true, events will be stored in a local instance of +CouchDB. If set to false, only a local log of events will be stored. +`create_history_log:` If true, a local log file will be created with all of the +block changes. +`couchdb_address:` is the local address for an off chain CouchDB database. + +### Create an instance of CouchDB + +If you set the "use_couchdb" option to true in `config.json`, you can run the +following command start a local instance of CouchDB using docker: + +``` +docker run --publish 5990:5984 --detach --name offchaindb couchdb:2.3.1 +docker start offchaindb +``` + + +### Install dependencies + +You need to install Node.js version 8.9.x to use the sample application code. +Execute the following commands to install the required dependencies: + +``` +npm install +``` + +### Starting the Channel Event Listener + +After we have installed the application dependencies, we can use the Node.js SDK +to create the identity our listener application will use to interact with the +network. Run the following command to enroll the admin user: +``` +node enrollAdmin.js +``` + +You can then run the following command to register and enroll an application +user: + +``` +node registerUser.js +``` + +We can then use our application user to start the block event listener: + +``` +node blockEventListener.js +``` + +If the command is successful, you should see the output of the listener reading +the configuration blocks of `mychannel` in addition to the blocks that recorded +the approval and commitment of the assets chaincode definition. + +`blockEventListener.js` creates a listener named "offchain-listener" on the +channel `mychannel`. The listener writes each block added to the channel to a +processing map called BlockMap for temporary storage and ordering purposes. +`blockEventListener.js` uses `nextblock.txt` to keep track of the latest block +that was retrieved by the listener. The block number in `nextblock.txt` may be +set to a previous block number in order to replay previous blocks. The file +may also be deleted and all blocks will be replayed when the block listener is +started. + +`BlockProcessing.js` runs as a daemon and pulls each block in order from the +BlockMap. It then uses the read-write set of that block to extract the latest +key value data and store it in the database. The configuration blocks of +mychannel did not any data to the database because the blocks did not contain a +read-write set. + +The channel event listener also writes metadata from each block to a log file +defined as channelid_chaincodeid.log. In this example, events will be written to +a file named `mychannel_basic.log`. This allows you to record a history of +changes made by each block for each key in addition to storing the latest value +of the world state. + +**Note:** Leave the blockEventListener.js running in a terminal window. Open a +new window to execute the next parts of the demo. + +### Generate data on the blockchain + +Now that our listener is setup, we can generate data using the assets chaincode +and use our application to replicate the data to our database. Open a new +terminal and navigate to the `fabric-samples/off_chain_data` directory. + +You can use the `addAssets.js` file to add random sample data to blockchain. +The file uses the configuration information stored in `addAssets.json` to +create a series of assets. This file will be created during the first execution +of `addAssets.js` if it does not exist. This program can be run multiple times +without changing the properties. The `nextAssetNumber` will be incremented and +stored in the `addAssets.json` file. + +``` + { + "nextAssetNumber": 100, + "numberAssetsToAdd": 20 + } +``` + +Open a new window and run the following command to add 20 assets to the +blockchain: + +``` +node addAssets.js +``` + +After the assets have been added to the ledger, use the following command to +transfer one of the assets to a new owner: + +``` +node transferAsset.js asset110 james +``` + +Now run the following command to delete the asset that was transferred: + +``` +node deleteAsset.js asset110 +``` + +## Offchain CouchDB storage: + +If you followed the instructions above and set `use_couchdb` to true, +`blockEventListener.js` will create two tables in the local instance of CouchDB. +`blockEventListener.js` is written to create two tables for each channel and for +each chaincode. + +The first table is an offline representation of the current world state of the +blockchain ledger. This table was created using the read-write set data from +the blocks. If the listener is running, this table should be the same as the +latest values in the state database running on your peer. The table is named +after the channelid and chaincodeid, and is named mychannel_basic in this +example. You can navigate to this table using your browser: +http://127.0.0.1:5990/mychannel_basic/_all_docs + +A second table records each block as a historical record entry, and was created +using the block data that was recorded in the log file. The table name appends +history to the name of the first table, and is named mychannel_basic_history +in this example. You can also navigate to this table using your browser: +http://127.0.0.1:5990/mychannel_basic_history/_all_docs + +### Configure a map/reduce view for summarizing counts of assets by color: + +Now that we have state and history data replicated to tables in CouchDB, we +can use the following commands query our off-chain data. We will also add an +index to support a more complex query. Note that if the `blockEventListener.js` +is not running, the database commands below may fail since the database is only +created when events are received. + +Open a new terminal window and execute the following: + +``` +curl -X PUT http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign -d '{"views":{"colorview":{"map":"function (doc) { emit(doc.color, 1);}","reduce":"function ( keys , values , combine ) {return sum( values )}"}}}' -H 'Content-Type:application/json' +``` + +Execute a query to retrieve the total number of assets (reduce function): + +``` +curl -X GET http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign/_view/colorview?reduce=true +``` + +If successful, this command will return the number of assets in the blockchain +world state, without having to query the blockchain ledger: + +``` +{"rows":[ + {"key":null,"value":19} + ]} +``` + +Execute a new query to retrieve the number of assets by color (map function): + +``` +curl -X GET http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign/_view/colorview?group=true +``` + +The command will return a list of assets by color from the CouchDB database. + +``` +{"rows":[ + {"key":"blue","value":2}, + {"key":"green","value":2}, + {"key":"purple","value":3}, + {"key":"red","value":4}, + {"key":"white","value":6}, + {"key":"yellow","value":2} + ]} +``` + +To run a more complex command that reads through the block history database, we +will create an index of the blocknumber, sequence, and key fields. This index +will support a query that traces the history of each asset. Execute the +following command to create the index: + +``` +curl -X POST http://127.0.0.1:5990/mychannel_basic_history/_index -d '{"index":{"fields":["blocknumber", "sequence", "key"]},"name":"asset_history"}' -H 'Content-Type:application/json' +``` + +Now execute a query to retrieve the history for the asset we transferred and +then deleted: + +``` +curl -X POST http://127.0.0.1:5990/mychannel_basic_history/_find -d '{"selector":{"key":{"$eq":"asset110"}}, "fields":["blocknumber","is_delete","value"],"sort":[{"blocknumber":"asc"}, {"sequence":"asc"}]}' -H 'Content-Type:application/json' +``` + +You should see the transaction history of the asset that was created, +transferred, and then removed from the ledger. + +``` +{"docs":[ +{"blocknumber":12,"is_delete":false,"value":"{\"docType\":\"asset\",\"name\":\"asset110\",\"color\":\"blue\",\"size\":60,\"owner\":\"debra\"}"}, +{"blocknumber":22,"is_delete":false,"value":"{\"docType\":\"asset\",\"name\":\"asset110\",\"color\":\"blue\",\"size\":60,\"owner\":\"james\"}"}, +{"blocknumber":23,"is_delete":true,"value":""} + ]} +``` + +## Getting historical data from the network + +You can also use the `blockEventListener.js` program to retrieve historical data +from your network. This allows you to create a database that is up to date with +the latest data from the network or recover any blocks that the program may +have missed. + +If you ran through the example steps above, navigate back to the terminal window +where `blockEventListener.js` is running and close it. Once the listener is no +longer running, use the following command to add 20 more assets to the +ledger: + +``` +node addAssets.js +``` + +The listener will not be able to add the new assets to your CouchDB database. +If you check the current state table using the reduce command, you will only +be able to see the original assets in your database. + +``` +curl -X GET http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign/_view/colorview?reduce=true +``` + +To add the new data to your off-chain database, remove the `nextblock.txt` +file that kept track of the latest block read by `blockEventListener.js`: + +``` +rm nextblock.txt +``` + +You can new re-run the channel listener to read every block from the channel: + +``` +node blockEventListener.js +``` + +This will rebuild the CouchDB tables and include the 20 assets that have been +added to the ledger. If you run the reduce command against your database one +more time, + +``` +curl -X GET http://127.0.0.1:5990/mychannel_basic/_design/colorviewdesign/_view/colorview?reduce=true +``` + +you will be able to see that all of the assets have been added to your +database: + +``` +{"rows":[ +{"key":null,"value":39} +]} +``` + +## Clean up + +If you are finished using the sample application, you can bring down the network +and any accompanying artifacts by running the following command: +``` +./network-clean.sh +``` + +Running the script will complete the following actions: + +* Bring down the Fabric test network. +* Takes down the local CouchDB database. +* Remove the certificates you generated by deleting the `wallet` folder. +* Delete `nextblock.txt` so you can start with the first block next time you + operate the listener. +* Removes `addAssets.json`. diff --git a/off_chain_data/addAssets.js b/off_chain_data/addAssets.js new file mode 100644 index 0000000..1137d5f --- /dev/null +++ b/off_chain_data/addAssets.js @@ -0,0 +1,118 @@ +/* + * Copyright IBM Corp.

In an ERC-20 account-based model, there is an account for each participant that holds a balance of tokens. +A mint transaction creates tokens in an account, while a transfer transaction debits the caller's account and credits another account. + +In this sample it is assumed that only one organization (played by Org1) is in a central banker role and can mint new tokens into their account, while any organization can transfer tokens from their account to a recipient's account. +Accounts could be defined at the organization level or client identity level. In this sample accounts are defined at the client identity level, where every authorized client with an enrollment certificate from their organization implicitly has an account ID that matches their client ID. +The client ID is simply a base64-encoded concatenation of the issuer and subject from the client identity's enrollment certificate. The client ID can therefore be considered the account ID that is used as the payment address of a recipient. + +In this tutorial, you will mint and transfer tokens as follows: + +- A member of Org1 uses the `Mint` function to create new tokens into their account. The `Mint` smart contract function reads the certificate information of the client identity that submitted the transaction using the `GetClientIdentity.GetID()` API and credits the account associated with the client ID with the requested number of tokens. +- The same minter client will then use the `Transfer` function to transfer the requested number of tokens to the recipient's account. It is assumed that the recipient has provided their account ID to the transfer caller out of band. The recipient can then transfer tokens to other registered users in the same fashion. + +## Bring up the test network + +You can run the ERC-20 token transfer scenario using the Fabric test network. Open a command terminal and navigate to the test network directory in your local clone of the `fabric-samples`. We will operate from the `test-network` directory for the remainder of the tutorial. +``` +cd fabric-samples/test-network +``` + +Run the following command to start the test network: +``` +./network.sh up createChannel -ca +``` + +The test network is deployed with two peer organizations. The `createChannel` flag deploys the network with a single channel named `mychannel` with Org1 and Org2 as channel members. +The -ca flag is used to deploy the network using certificate authorities. This allows you to use each organization's CA to register and enroll new users for this tutorial. + +## Deploy the smart contract to the channel + +You can use the test network script to deploy the ERC-20 token contract to the channel that was just created. Deploy the smart contract to `mychannel` using the following command: + +**For a Go Contract:** +``` +./network.sh deployCC -ccn token_erc20 -ccp ../token-erc-20/chaincode-go/ -ccl go +``` + +**For a JavaScript Contract:** +``` +./network.sh deployCC -ccn token_erc20 -ccp ../token-erc-20/chaincode-javascript/ -ccl javascript +``` + +The above command deploys the go chaincode with short name `token_erc20`. The smart contract will use the default endorsement policy of majority of channel members. +Since the channel has two members, this implies that we'll need to get peer endorsements from 2 out of the 2 channel members. + +Now you are ready to call the deployed smart contract via peer CLI calls. But let's first create the client identities for our scenario. + +## Register identities + +The smart contract supports accounts owned by individual client identities from organizations that are members of the channel. In our scenario, the minter of the tokens will be a member of Org1, while the recipient will belong to Org2. To highlight the connection between the `GetClientIdentity().GetID()` API and the information within a user's certificate, we will register two new identities using the Org1 and Org2 Certificate Authorities (CA's), and then use the CA's to generate each identity's certificate and private key. + +First, we need to set the following environment variables to use the Fabric CA client (and subsequent commands). +``` +export PATH=${PWD}/../bin:${PWD}:$PATH +export FABRIC_CFG_PATH=$PWD/../config/ +``` + +The terminal we have been using will represent Org1. We will use the Org1 CA to create the minter identity. Set the Fabric CA client home to the MSP of the Org1 CA admin (this identity was generated by the test network script): +``` +export FABRIC_CA_CLIENT_HOME=${PWD}/organizations/peerOrganizations/org1.example.com/ +``` + +You can register a new minter client identity using the `fabric-ca-client` tool: +``` +fabric-ca-client register --caname ca-org1 --id.name minter --id.secret minterpw --id.type client --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem +``` + +You can now generate the identity certificates and MSP folder by providing the minter's enroll name and secret to the enroll command: +``` +fabric-ca-client enroll -u https://minter:minterpw@localhost:7054 --caname ca-org1 -M ${PWD}/organizations/peerOrganizations/org1.example.com/users/minter@org1.example.com/msp --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem +``` + +Run the command below to copy the Node OU configuration file into the minter identity MSP folder. +``` +cp ${PWD}/organizations/peerOrganizations/org1.example.com/msp/config.yaml ${PWD}/organizations/peerOrganizations/org1.example.com/users/minter@org1.example.com/msp/config.yaml +``` + +Open a new terminal to represent Org2 and navigate to fabric-samples/test-network. We'll use the Org2 CA to create the Org2 recipient identity. Set the Fabric CA client home to the MSP of the Org2 CA admin: +``` +cd fabric-samples/test-network +export PATH=${PWD}/../bin:${PWD}:$PATH +export FABRIC_CA_CLIENT_HOME=${PWD}/organizations/peerOrganizations/org2.example.com/ +``` + +You can register a recipient client identity using the `fabric-ca-client` tool: +``` +fabric-ca-client register --caname ca-org2 --id.name recipient --id.secret recipientpw --id.type client --tls.certfiles ${PWD}/organizations/fabric-ca/org2/tls-cert.pem +``` + +We can now enroll to generate the recipient's identity certificates and MSP folder: +``` +fabric-ca-client enroll -u https://recipient:recipientpw@localhost:8054 --caname ca-org2 -M ${PWD}/organizations/peerOrganizations/org2.example.com/users/recipient@org2.example.com/msp --tls.certfiles ${PWD}/organizations/fabric-ca/org2/tls-cert.pem +``` + +Run the command below to copy the Node OU configuration file into the recipient identity MSP folder. +``` +cp ${PWD}/organizations/peerOrganizations/org2.example.com/msp/config.yaml ${PWD}/organizations/peerOrganizations/org2.example.com/users/recipient@org2.example.com/msp/config.yaml +``` + +## Mint some tokens + +Now that we have created the identity of the minter, we can invoke the smart contract to mint some tokens. +Shift back to the Org1 terminal, we'll set the following environment variables to operate the `peer` CLI as the minter identity from Org1. +``` +export CORE_PEER_TLS_ENABLED=true +export CORE_PEER_LOCALMSPID="Org1MSP" +export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/minter@org1.example.com/msp +export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt +export CORE_PEER_ADDRESS=localhost:7051 +export TARGET_TLS_OPTIONS="-o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" +``` + +The last environment variable above will be utilized within the CLI invoke commands to set the target peers for endorsement, and the target ordering service endpoint and TLS options. + +We can then invoke the smart contract to mint 5000 tokens: +``` +peer chaincode invoke $TARGET_TLS_OPTIONS -C mychannel -n token_erc20 -c '{"function":"Mint","Args":["5000"]}' +``` + +The mint function validated that the client is a member of the minter organization, and then credited the minter client's account with 5000 tokens.

For example: + +* Rather than using the default 'majority' endorsement policy, you could set the endorsement policy to a subset of organizations that represent trust anchors for the contract execution. +* You could also require that accounts get setup before use, and apply state-based endorsement for each account key that has been created. For example on an Org1 account, set state-based endorsement policy to be Org1 and the central banker (or some other trust anchor). And on an Org2 account, set state-based endorsement policy to be Org2 and the central banker (or some other trust anchor). Then to transfer tokens from an Org1 account to an Org2 account, you would require endorsements from Org1, Org2, and the central banker (or some other trust anchor). +* You could utilize anonymous addresses for accounts based on private-public key pairs, instead of accounts keyed by the client ID. In order to spend the tokens, the client would have to sign the transfer input as proof that they own the address private key, which the contract would then validate, similar to the Ethereum model in the permissionless blockchain space. However, in a permissioned blockchain such as Fabric, only registered clients are authorized to participate. Furthermore, if you don't want to leak the registered client identity associated with each account, the clients could be registered using an Identity Mixer MSP, so that the client itself is also anonymous in each of the token transactions. diff --git a/token-erc-20/chaincode-go/chaincode/token_contract.go b/token-erc-20/chaincode-go/chaincode/token_contract.go new file mode 100644 index

In a UTXO model, unspent transaction outputs representing a number of tokens can be 'spent' to transfer tokens between participants. +An unspent transaction output can only be spent once, and the full value must be completely spent. A transaction that spends UTXOs as input will also generate new UTXOs as outputs, where the value of the inputs must equal the value of the outputs. As an example, if you own an unspent transaction output representing 5000 tokens, and you need to transfer 100 tokens to a recipient, the transaction would spend the 5000 token UTXO as input, create a new 100 token UTXO output owned by the recipient, and return a new 4900 token UTXO to you as 'change'. + +Each UTXO in this sample has a key derived from the transaction id that created it, as well as a number of tokens, and an owner that is authorized to spend the tokens. +Ownership of each UTXO could be represented at the organization level or client identity level. In this sample UTXO ownership is based on a client identity, where the client ID is simply a base64-encoded concatenation of the issuer and subject from the client identity's enrollment certificate. The client ID can therefore be used as the payment address when transferring tokens in a UTXO transaction. + +While a transfer transaction spends UTXOs and creates new UTXOs for the recipient(s), a mint transaction can create new UTXOs. In this sample it is assumed that only one organization (played by Org1) is in a central banker role and can mint new tokens owned by their client ID. Any client from any organization can transfer tokens in a UTXO transaction. + +In this tutorial, you will mint and transfer tokens as follows: + +- A member of Org1 uses the `Mint` function to create a UTXO representing a number of tokens. The `Mint` function reads the certificate information of the client identity that submitted the transaction using the `GetClientIdentity.GetID()` API and assigns the UTXO ownership to the minter client ID. +- The same minter client will then use the `Transfer` function to transfer the requested number of tokens to a recipient. The minted UTXO key gets passed as input to the `Transfer` function, a UTXO output representing the number of transferred tokens gets created for the recipient, and another UTXO output representing the 'change' gets created for the minter. It is assumed that the recipient has provided their client ID to the transfer caller out of band. The recipient can then transfer tokens to other registered users in the same fashion. + +## Bring up the test network + +You can run the UTXO token transfer scenario using the Fabric test network. Open a command terminal and navigate to the test network directory in your local clone of the `fabric-samples`. We will operate from the `test-network` directory for the remainder of the tutorial. +``` +cd fabric-samples/test-network +``` + +Run the following command to start the test network: +``` +./network.sh up createChannel -ca +``` + +The test network is deployed with two peer organizations. The `createChannel` flag deploys the network with a single channel named `mychannel` with Org1 and Org2 as channel members. +The -ca flag is used to deploy the network using certificate authorities. This allows you to use each organization's CA to register and enroll new users for this tutorial. + +## Deploy the smart contract to the channel + +You can use the test network script to deploy the UTXO token contract to the channel that was just created. Deploy the smart contract to `mychannel` using the following command: +``` +./network.sh deployCC -ccn token_utxo -ccp ../token-utxo/chaincode-go/ -ccl go +``` + +The above command deploys the go chaincode with short name `token_utxo`. The smart contract will utilize the default endorsement policy of majority of channel members. +Since the channel has two members, this implies that we'll need to get peer endorsements from 2 out of the 2 channel members. + +Now you are ready to call the deployed smart contract via peer CLI calls. But let's first create the client identities for our scenario. + +## Register identities + +The smart contract supports UTXO ownership based on individual client identities from organizations that are members of the channel. In our scenario, the minter of the tokens will be a member of Org1, while the recipient will belong to Org2. To highlight the connection between the `GetClientIdentity().GetID()` API and the information within a user's certificate, we will register two new identities using the Org1 and Org2 Certificate Authorities (CA's), and then use the CA's to generate each identity's certificate and private key. + +First, we need to set the following environment variables to use the the Fabric CA client (and subsequent commands) +``` +export PATH=${PWD}/../bin:${PWD}:$PATH +export FABRIC_CFG_PATH=$PWD/../config/ +``` + +The terminal we have been using will represent Org1. We will use the Org1 CA to create the minter identity. Set the Fabric CA client home to the MSP of the Org1 CA admin (this identity was generated by the test network script): +``` +export FABRIC_CA_CLIENT_HOME=${PWD}/organizations/peerOrganizations/org1.example.com/ +``` + +You can register a new minter client identity using the `fabric-ca-client` tool: +``` +fabric-ca-client register --caname ca-org1 --id.name minter --id.secret minterpw --id.type client --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem +``` + +You can now generate the identity certificates and MSP folder by providing the enroll name and secret to the enroll command: +``` +fabric-ca-client enroll -u https://minter:minterpw@localhost:7054 --caname ca-org1 -M ${PWD}/organizations/peerOrganizations/org1.example.com/users/minter@org1.example.com/msp --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem +``` + +Run the command below to copy the Node OU configuration file into the minter identity MSP folder. +``` +cp ${PWD}/organizations/peerOrganizations/org1.example.com/msp/config.yaml ${PWD}/organizations/peerOrganizations/org1.example.com/users/minter@org1.example.com/msp/config.yaml +``` + +Open a new terminal to represent Org2 and navigate to fabric-samples/test-network. We'll use the Org2 CA to create the Org2 recipient identity.

Here is the returned UTXO with JSON formatting applied: +``` +{ + "utxo_key":"c3706696c537e7bd6940fedfd52f4a3a630d253297db0ecc2b3ba514b45f5e7c.0", + "owner":"eDUwOTo6Q049bWludGVyLE9VPWNsaWVudCxPPUh5cGVybGVkZ2VyLFNUPU5vcnRoIENhcm9saW5hLEM9VVM6OkNOPWNhLm9yZzEuZXhhbXBsZS5jb20sTz1vcmcxLmV4YW1wbGUuY29tLEw9RHVyaGFtLFNUPU5vcnRoIENhcm9saW5hLEM9VVM=", + "amount":5000 +} +``` + +Notice that the utxo_key is set to the transaction id, concatenated with ".0" to indicate that this is the first (and only) UTXO output of the transaction.

We'll pass in the utxo_key of the UTXO with 5000 tokens to spend, and request that two new UTXOs get created, a UTXO with 100 tokens for the recipient, and a UTXO with 4900 tokens for the minter as the 'change'.

The command will remove all the nodes of the test network, and delete any ledger data that you created: +``` +./network.sh down +``` + +## Contract extension ideas + +You can extend the basic UTXO token sample to meet other requirements. For example: + +* Rather than using the default 'majority' endorsement policy, you could set the endorsement policy to a subset of organizations that represent trust anchors for the contract execution. +* You could utilize anonymous payment addresses on the UTXO outputs based on private-public key pairs, instead of UTXOs assigned to a client ID. In order to spend the tokens, the client would have to sign the transfer input as proof that they own the address private key, which the contract would then validate, similar to the Bitcoin model in the permissionless blockchain space. However, in a permissioned blockchain such as Fabric, only registered clients are authorized to participate. Furthermore, if you don't want to leak the registered client identity associated with each address, the clients could be registered using an Identity Mixer MSP, so that the client itself is also anonymous in each of the token transactions. diff --git a/token-utxo/chaincode-go/chaincode/token_contract.go b/token-utxo/chaincode-go/chaincode/token_contract.go new file mode 100644 index
