What is the precise format to modify the bits and configurations in bitcoin mining
You gather together the data for a block according to the block definition. You don’t have to include any transactions other than the coinbase transaction you create that pays you your block reward + fees from any included transactions.
If you want to include transactions, the transaction data in the block must follow the transaction data definition
Then you have to calculate the Merkle root and insert that into the block header
to get sufficient leading 0s in the hash
The number of leading zeroes is not relevant.
You check the hash of the block is less than the current network target.
If it isn’t you change the value of the nonce in the block header and try again. If you have tried all nonce values, you change the extranonce or re-order or re-select the transactions etc and try again.
Is there open source software with documentation?
However In the ASIC-age, is it worth starting mining Bitcoin at home?
So you are perhaps interested in software for managing mining rigs that are based on ASICs.
