why there are 3 transactions in Block 0, but there no transactionReceipts of these 3 transactions?

[PikaZ76]

I'm new guy and very interesting in Tron, but I notice there are 3 transactions in block 0, but can't get transactionReceipts for these transactions,

so what happend for transactions in block 0? why the transaction receipts or transaction Info were missed in api ?
jsonrpc call:

{
	"jsonrpc": "2.0",
	"method": "eth_getBlockByNumber",
	"params": [0, true],
	"id": 1
}

we can see there are 3 transactions in this block:

{
    "jsonrpc": "2.0",
    "id": 1,
    "result": {
        "baseFeePerGas": "0x0",

        "uncles": []
    }
}

but there are no result for method eth_getTransactionReceipt:

{
	"jsonrpc": "2.0",
	"method": "eth_getTransactionReceipt",
	"params": ["0x788b4d0ca432b3d07f895dffe80429bf58398d0e86222460b07f9db38e238803"],
	"id": 1
}

{
	"jsonrpc": "2.0",
	"method": "eth_getTransactionReceipt",
	"params": ["0xdfb4a633165cb85963ec1edfb4c9283644a3e136b77c063f4ba2e39307863a75"],
	"id": 1
}

{
	"jsonrpc": "2.0",
	"method": "eth_getTransactionReceipt",
	"params": ["0x25b18a55f86afb10e7aca38d0073d04c80397c6636069193953fdefaea0b8369"],
	"id": 1
}

they all get this...

{
    "jsonrpc": "2.0",
    "id": 1,
    "result": null
}

also empty for wallet/gettransactioninfobyblocknum by post {"num":0}:

{}

@PikaZ76 transactionReceipts feature was not there at the beginning, so if one node is started using the snapshot, it is possible that there is no transactionReceipts for the earliest blocks. If you want to get the receipt of transaction in all blocks. you need to start a node and make it sync and process from the very first block, and it will take lots of time.

[PikaZ76]

thanks~

@ferdinand026
I deploied a node without any snapshot, it's sync from Block-0, it should be right to get txReceipts for 3 transactions in Block-0, but I just still get same response with empty transaction reciepts and transactionInfo Block-0

post: /wallet/gettransactioninfobyblocknum
data: {"num":	0}

response:
{}

but other blocks get empty response of

post: /wallet/gettransactioninfobyblocknum
data: {"num":	1}

response:
[]

Is the data not synchronized properly?

[PikaZ76]

@ferdinand026 @King31T I tried this after the node started without snapshot and had synced 2,000 blocks. When I sent a request to check Block-0, the API was able to return the block data, which contained 3 transactions.

Does this mean the transaction receipt didn't take effect immediately and I need to wait for a specific state for them to apply?

Is it possible that 'eth_getTransactionReceipt' does not support blocks before its implementation?

@ferdinand026 yes, you do need to wait for java-tron finish syncing the blocks you required.

[Sunny6889]

@King31T rpc method eth_getTransactionReceipt is equal to http wallet/getTransactionInfoById. As long as the requested fullnode contains the transaction info it should return correctly.

[King31T]

@Sunny6889 Got it, Thx.

[Sunny6889]

@King31T To clarify in more detail:

• wallet/gettransactioninfobyblocknum will return data when the block number is greater than 0 and the block contains transactions. For earlier blocks produced before the year 2019 or blocks with numbers less than 10 million, there is a high chance that the block does not contain transactions, and thus it will return an empty response.
• wallet/getblockbynum with "num": 0 does return the genesis transaction information, with only basic raw_data info, which initializes certain account balances. However, this is not like a transaction initiated by an external request, as it does not include signature, ref_block, expiration, or contractRet.
• wallet/gettransactioninfobyid and wallet/gettransactioninfobyid only return transactions initiated by external requests. As a result, if you query the three transactions returned by wallet/getblockbynum with "num": 0, they will return empty.
• Finally, requests that hit the TRON fullnode(locally or remotely) will only check the server's own database. Therefore, you also need to ensure that the requested blocks are synced. You could verify the data use TronScan.

@Sunny6889
Regarding the third pointwallet/gettransactioninfobyid, could you give a more detail explanation about the causal relationship?

[Sunny6889]

@King31T Sorry I don't get your question. What do you mean causal relationship?
