Field notes
The workflow starts with seed generation on a clean offline computer; the printed book is split across two printers, and a public registration file carries no secrets. After online proof-of-work registration and an approximately two-hour wait, the account number is finalized. The site links a working paper, parameter-by-parameter design specification, FAQ, source and tests (about 2,500 lines of Rust), plus network explorer and node-status pages.
