BLOCK PARAMETER
- the block number, or one of the following string values:
"latest"
- the most recent block"earliest"
- the genesis block"pending"
- the pending block"safe"
- the most recent safe block"finalized"
- the most recent finalized blockUNCLE INDEX POSITION
- the uncle’s index position. It’s a hexadecimal value representing the uncle’s position in the block’s uncle list.result
— A block object with uncle information, or null when no uncle exists at the given index. The block object includes:
number
: The block numberhash
: Hash of the uncle blockparentHash
: Hash of the parent blocknonce
: Hash of the generated proof-of-worksha3Uncles
: SHA3 of the uncles data in the blocklogsBloom
: The bloom filter for the logs of the blocktransactionsRoot
: The root of the transaction trie of the blockstateRoot
: The root of the final state trie of the blockreceiptsRoot
: The root of the receipts trie of the blockminer
: The address of the beneficiary to whom the mining rewards were givendifficulty
: Integer of the difficulty for this blocktotalDifficulty
: Integer of the total difficulty of the chain until this blockextraData
: The “extra data” field of this blocksize
: Integer the size of this block in bytesgasLimit
: The maximum gas allowed in this blockgasUsed
: The total used gas by all transactions in this blocktimestamp
: The unix timestamp for when the block was collatedeth_getUncleByBlockNumberAndIndex
method is primarily used in proof-of-work networks for:
