### LockZKP

**Bounty Prompt:** A PoC smart lock contract to mutually authenticate the owner, the
smartlock and the guest. This project is unique in the sense that it uses a
challenge-response protocol along with Owner and Guest proofs to make it
decentralized while allowing for the smartlock to be offline and not having to run a
blockchain node or client. </br>

- Edit: Just discovered https://wrapeth.com/, existed for 2+ years, and is open source. This bounty is no longer offered!
- ~~Add a nice frontend to https://github.com/nulven/zk-message-board, and build a proof-of-concept anonymous group posting app powered by zero-knowledge proofs.~~

- **LockZKP**: A PoC smart lock contract to mutually authenticate the owner, the
smartlock and the guest. This project is unique in the sense that it uses a
challenge-response protocol along with Owner and Guest proofs to make it
decentralized while allowing for the smartlock to be offline and not having to run a
blockchain node or client. The smart contract with guest/owner registration, guest room bidding, guest auth, owner auth and lock auth. The backend nodejs challenge-response protocol uses Kobiltz’s encoding over elliptic curve points.
The owner proving happens in the cicrom/groth16 proving system. Integrates
[semaphore-protocol](https://github.com/semaphore-protocol/semaphore) for family members or friends to cryptographically prove identity to skip the auction phase of the authentication process. Also integrated [Waku p2p protocol](https://github.com/waku-org/js-waku) to establish a private communication channel between the Owner and Guest post authentication. The final step of shared key establishment between the Guest and the Lock by having the Guest Pair his/her phone by tapping it to the Lock (NFC communication for security). As a bonus the Lock also generates a 8 digit PIN
(HOTP) for the Guest as a backup manual key.
- DONE: This is done at [LockZKP](https://github.com/rohanjacin/lockcontractZKP).
