- Confirm the SHA-256 of the downloaded file matches the seal shown on this page.
- Confirm the target Bitcoin block height/hash on a public block explorer.
- Compute the winning ticket using the published formula and the sealed ticket count (N).
- Confirm the winner shown matches the computed ticket.
