There were many questions about this topic in this forum, but I checked most of this topic, but I can’t find a solution to my work. I am creating my own algorithm for solo mining bitcoin in Python. I wrote all the necessary methods, including hacking and block header calculations. But now it is trapped for several weeks in Coinbase Transaction. I tried to study Coinbase Transaction Page and implement all logic on Learnmeabitcoin.com, but I can’t fully understand how to make one. I want to include new rules (BIP34 -block headers, BIP141 -SEGWIT TX) in this algorithm, but my knowledge of hasings is not enough. : (
Can someone provide more data, some code samples, or explain the details of the creation of coinbase transactions? All information will be very helpful. I hope it will help.
In addition, in the regtest mode, we are being trained in Bitcoin Core and when used "GenerateToadDress" How to set more configuration for this configuration because this one method (for creation block) does not generate Coinbase TX using BIP34 and BIP141 requirements? Someone found something about BlockVersion Arg. Is it true?
Thank you all ^^
Pusin: If you miss the details of my mission, I asked for free and provides all the information I have, the code sample I have.
Update
I have a Great News. Find the solution and complete it. But only one question remained, I used an object for the creation of TX on the screen, and there was a slight difference from the Coinbase TX with the Bitcoin Core created using only one place in one place, and submitted N to the first output. "00000000"Like 0 in Little-Endian with 4 bytes. Can someone explain what it is? Use the P2WPKH script for the hasings address. Perhaps the type of this? All of these values worked well, and after successfully performing Coinbasetx Gen after the BUILD Block header and the entire block. But just understand my code completely "00000000" Average) name "N" The field was by me.
