Verify any read

Before a read is generated we create a secret server seed and show you its SHA-256 hash. You supply the client seed. The read is bound to HMAC_SHA256(serverSeed, clientSeed:nonce), so the outcome cannot be changed after the fact.

1. I. Copy the server seed hash shown with your prediction.
2. II. Once the seed is revealed, paste it below.
3. III. The hash must match, and the digest must match the one stored with your read.
