Verify Hookedin rounds offline
This standalone Node.js script lets partners and players reproduce the winning ticket calculation from the ticket digits and closing block hash. It uses only Node.js built-in modules.
Recommended workflow
- Open a settled round in the Hookedin website or choose a round number from /rounds.
- Copy the closing block hash from the round proof panel.
- Run verify-winning-ticket.cjs with that hash and the configured ticket digit count.
- Compare the utility output with the website's displayed winning ticket.
node verify-winning-ticket.cjs --closing-block-hash <hash> --ticket-digits 8
Command examples
