$ ./verify --provably-fair
—————verify: sha256(revealed_server_seed) == old_server_seed_hash
// how to verify
Every settled bet returns a proof:
{server_seed_hash, client_seed, nonce}.
Outcome bytes are derived as:
HMAC_SHA256( key = server_seed, msg = "client_seed:nonce:cursor" )
The server commits to server_seed up front by publishing
its sha256. After you rotate, the old seed is
revealed: confirm sha256(revealed) == server_seed_hash,
then replay each nonce through the HMAC to reproduce every result.
No trust required.
