Oh ! To read the .blk files and convert them to usable structs, I’m using a strip down version this library which is sadly archived and doesn’t work with latest version of bitcoin rust. I had so much on my plate already that I just took what I needed and updated it to make it work

What’s nice is that I uses a parr sync iterator to read in advance the block files that you’ll read later while still being synchronous which makes the parsing of the files 60% faster I believe.

You can find the code with credits in parser/bitcoin/db
