How to reproduce this yourself
1. Confirm the server hash:
2. Re-derive the values: HMAC-SHA256(serverSeed,
3. Confirm the public hash on the verify form: Open in /verify →

1. Confirm the server hash:
sha256(serverSeed) === serverHash — once the seed is revealed (after the cursor advances), this hash will match it.2. Re-derive the values: HMAC-SHA256(serverSeed,
"vrf-alternative-demo:5:<round>"), then map bytes to ints.3. Confirm the public hash on the verify form: Open in /verify →
