Provably fair at Stake: what a SHA-256 commitment can and cannot show

Direct answer

Stake publishes a commitment-and-seed model for Originals. The local walkthrough can reproduce a SHA-256 commitment from text you enter, but it does not recreate every game result or audit Stake's implementation.

Last verified:

Verification is narrow: first prove that a revealed value matches a prior hash commitment, then apply the game's documented result algorithm separately.

Key facts

The local walkthrough computes SHA-256 from the exact UTF-8 input bytes in the browser without sending the input to Stake.

Commit before reveal

A server can publish a hash commitment before revealing the underlying value. After reveal, hashing the exact same bytes should reproduce the commitment.

Reproduce the SHA-256 hash

Enter the example value, calculate locally and compare the hexadecimal digest character for character. Encoding and punctuation matter.

A matching commitment is only one check

You still need the game's documented combination and mapping rules to reproduce a result. This walkthrough makes no claim about undisclosed code.

Practical steps

  1. Record the commitment before the value is revealed.

  2. Preserve the exact revealed text and encoding.

  3. Calculate SHA-256 locally.

  4. Compare the full hexadecimal digest.

  5. Use the separate game algorithm only when it is fully documented.

SHA-256 commitment demonstration

Hexadecimal digest

The demonstration hashes only the entered text. It does not verify a game result or audit the platform.

Troubleshooting

The digest does not match

  • Check whitespace, capitalization and encoding.
  • Confirm that the recorded commitment and revealed value belong together.

A mismatch means the exact inputs differ; it does not identify which party or step caused the difference.

Who this guide suits

  • Readers learning commitment verification.
  • Readers comparing a revealed value with a recorded hash.

Who should avoid or pause

  • Anyone treating one matching hash as proof of platform-wide fairness.
  • Anyone expecting the tool to predict a result.

What the records help with

  • The commitment check is reproducible and local.
  • The guide separates hash verification from result calculation.

What remains unresolved

  • The walkthrough is not a game-specific verifier.

Frequently asked questions

What does provably fair mean here?

It refers to a documented commitment and verification model, not a guarantee that gambling is safe or profitable.

Does the tool connect to Stake?

No. It runs a local, generic SHA-256 example and sends no input.

Can it predict the next result?

No. It does not predict or influence results.
