Can a Quantum Computer Break the Security of a Standard Hash-Based Commit-Reveal Scheme?

No, a quantum computer would not break the security of a standard hash-based commit-reveal scheme in the same way it breaks public-key cryptography (like RSA). While quantum algorithms (like Grover's algorithm) can speed up the search for a hash collision, they do not make it trivial.

The security can be maintained by simply doubling the hash size (e.g. moving from SHA-256 to SHA-512) to compensate for the quantum speedup, making the scheme quantum-resistant.

Glossar

Commitment Scheme

Mechanism ⎊ A commitment scheme, within cryptocurrency and financial derivatives, establishes a verifiable agreement on a future value without revealing it prematurely; this is crucial for applications like time-locked transactions and decentralized exchanges, ensuring trustless execution of complex strategies.

Commit-Reveal

Mechanism ⎊ Commit-Reveal protocols, within decentralized finance, represent a staged disclosure of trading intentions, initially committing to a transaction and subsequently revealing the specifics.
