eth_getUncleByBlockHashAndIndex

Telcoin Network’s consensus produces no uncle blocks, so this method always returns null. It is served for Ethereum API compatibility.

Parameters

DATA, 32 Bytes - Hash of a block.

QUANTITY - Hexadecimal of the uncle’s index position.

Returns

Object - A block object, or null when no block was found:

  • number: QUANTITY - Hexadecimal of the block number. null when its pending block.
  • hash: DATA, 32 Bytes - Hash of the block. null when its pending block.
  • parentHash: DATA, 32 Bytes - Hash of the parent block.
  • nonce: DATA, 8 Bytes - Hash of the generated proof-of-work. null when its pending block.
  • sha3Uncles: DATA, 32 Bytes - SHA3 of the uncles data in the block.
  • logsBloom: DATA, 256 Bytes - The bloom filter for the logs of the block. null when its pending block.
  • transactionsRoot: DATA, 32 Bytes - The root of the transaction trie of the block.
  • stateRoot: DATA, 32 Bytes - The root of the final state trie of the block.
  • receiptsRoot: DATA, 32 Bytes - The root of the receipts trie of the block.
  • miner: DATA, 20 Bytes - The address of the beneficiary to whom the mining rewards were given.
  • difficulty: QUANTITY - Hexadecimal of the difficulty for this block.
  • totalDifficulty: QUANTITY - Hexadecimal of the total difficulty of the chain until this block.
  • extraData: DATA - The “extra data” field of this block.
  • size: QUANTITY - Hexadecimal size of this block in bytes.
  • gasLimit: QUANTITY - Hexadecimal of the maximum gas allowed in this block.
  • gasUsed: QUANTITY - Hexadecimal of the total used gas by all transactions in this block.
  • timestamp: QUANTITY - Hexadecimal of the unix timestamp for when the block was collated.
  • transactions: Array - Array of transaction objects, or 32 Bytes transaction hashes depending on the last given parameter.
  • uncles: Array - Array of uncle hashes.
