Four documents and a licence
Short, plain, and written to be checked against the code rather than admired.
WHITEPAPER.md
The two constants, the emission proof, difficulty, block limits and the things deliberately left out. If a number on this site disagrees with the whitepaper, the whitepaper is wrong and should be fixed.
MINING.md
RandomX setup, memory per thread, huge pages, the solo command line, and what a pool would actually change — including the part pools rarely mention, that a pool holds your coins while they sit in its balance.
WALLET.md
Keys, backups, and the rule a published hash has to pass: full length, copied from one source, printed before the file and not after.
TRANSPARENCY.md
The order in which parts get published, written down before there was anything to publish — so that "soon" has a definition and a missed date is visible rather than quietly reworded.
MIT
The whole project is MIT. Fork it, audit it, ship your own version; the only thing the licence asks is that the notice stays attached.
