proof namespace

proof_getTransactionByHash

Returns the same data as eth_getTransactionByHash plus a Merkle-Patricia proof of the transaction's inclusion in the block's transactionsRoot. When includeHeader is true, the RLP-encoded block header is also returned, allowing the proof to be verified against the block's transactionsRoot.

Parameters

1. txHash: string (hash)

2. includeHeader: boolean

  --data '{
      "jsonrpc": "2.0",

      "method": "proof_getTransactionByHash",
      "params": [txHash, includeHeader]
    }'

Response

  "id": 0,
  "result": result
}

result: object

• blockHeader: string (hex data)
• transaction: object
  • blockHash: string (hash)
  • blockNumber: string (hex integer)
  • blockTimestamp: string (hex integer)
  • gas: string (hex integer)
  • hash: string (hash)
  • transactionIndex: string (hex integer)
  • type: integer
• txProof: array of string (hex data)

proof_getTransactionReceipt

Returns the same data as eth_getTransactionReceipt plus Merkle-Patricia proofs of the transaction's inclusion in the block's transactionsRoot and of the receipt's inclusion in the block's receiptsRoot. When includeHeader is true, the RLP-encoded block header is also returned, allowing proofs to be verified against the block's roots.

Parameters

1. txHash: string (hash)

2. includeHeader: boolean
