I refer to this document for using getBlock
rpc api.
https://bitcoin.org/en/developer-reference#getblock
{
"hash" : "hash", (string) the block hash (same as provided)
"confirmations" : n, (numeric) The number of confirmations, or -1 if the block is not on the main chain
"size" : n, (numeric) The block size
"strippedsize" : n, (numeric) The block size excluding witness data
"weight" : n (numeric) The block weight as defined in BIP 141
"height" : n, (numeric) The block height or index
"version" : n, (numeric) The block version
"versionHex" : "00000000", (string) The block version formatted in hexadecimal
"merkleroot" : "xxxx", (string) The merkle root
"tx" : [ (array of string) The transaction ids
"transactionid" (string) The transaction id
,...
],
"time" : ttt, (numeric) The block time in seconds since epoch (Jan 1 1970 GMT)
"mediantime" : ttt, (numeric) The median block time in seconds since epoch (Jan 1 1970 GMT)
"nonce" : n, (numeric) The nonce
"bits" : "1d00ffff", (string) The bits
"difficulty" : x.xxx, (numeric) The difficulty
"chainwork" : "xxxx", (string) Expected number of hashes required to produce the chain up to this block (in hex)
"nTx" : n, (numeric) The number of transactions in the block.
"previousblockhash" : "hash", (string) The hash of the previous block
"nextblockhash" : "hash" (string) The hash of the next block
}
I want to know meaning size
and bits
- What is
size
field mean?? block size as byte?? - What is
bits
field mean?? block size as bits??
May I use chainwork diff for calculating hash power for each block?
According to this doc, https://bitcoin.org/en/developer-reference#getblock, chainwork
means
"chainwork": "xxxx" (string) total amount of work in active chain, in hexadecimal
For example, let's assume that chainwork of block 12345 is 1111 and that of block 12344 is 1100.
Then may I consider that hash power for block 12345 is 11 since 1111 - 1100 is 11?
