eth_getUncleByBlockNumberAndIndex

Returns information about a uncle of a block by number and uncle index position.
Parameters
Params - a string array containing (required):
QUANTITY|TAG(hex string|string, required) - integer block number in hex string format, or the string "earliest", "latest" or "pending", as in the default block parameter.
QUANTITY(hex string, required) - the uncle’s index position.
Returns
Object - A block object, or null when no block was found:
number(hex string). QUANTITY - the block number. null when its pending block.
hash(hex string). DATA, 32 Bytes - hash of the block. null when its pending block.
parentHash(hex string). DATA, 32 Bytes - hash of the parent block.
nonce(hex string). DATA, 8 Bytes - hash of the generated proof-of-work. null when its pending block.
sha3Uncles(hex string). DATA, 32 Bytes - SHA3 of the uncles data in the block.
logsBloom(hex string). DATA, 256 Bytes - the bloom filter for the logs of the block. null when its pending block.
transactionsRoot(hex string). DATA, 32 Bytes - the root of the transaction trie of the block.
stateRoot(hex string). DATA, 32 Bytes - the root of the final state trie of the block.
receiptsRoot(hex string). DATA, 32 Bytes - the root of the receipts trie of the block.
miner(hex string). DATA, 20 Bytes - the address of the beneficiary to whom the mining rewards were given.
difficulty(hex string). QUANTITY - integer of the difficulty for this block.
totalDifficulty(hex string). QUANTITY - integer of the total difficulty of the chain until this block.
extraData(hex string). DATA - the “extra data” field of this block.
size(hex string). QUANTITY - integer the size of this block in bytes.
gasLimit(hex string). QUANTITY - the maximum gas allowed in this block.
gasUsed(hex string). QUANTITY - the total used gas by all transactions in this block.
timestamp(hex string). QUANTITY - the unix timestamp for when the block was collated.
transactions(array of object). Array - array of transaction objects, or 32 Bytes transaction hashes depending on the last given parameter.
