Bitcoin Cash: Post-Quantum Verifier goes live on BCH chipnet - 14 Aug 2026

A post-quantum-safe proof verifier is live on BCH chipnet, according to the announcement. The 9,930-byte verifier fits in a single input, providing a compact on-chain program for checking whether a mathematical proof is valid.

The release demonstrates a distinctive cryptographic capability within the BCH ecosystem. Its design is intended to let the network verify proofs while addressing the risk that future quantum computers could compromise current cryptographic methods. Fitting the verifier into one input also shows that this proof-checking function can be packaged in a small on-chain program.

The demonstration may provide evidence of longer-term protocol innovation, but availability on chipnet does not establish a mainnet deployment or broader adoption.

The first post-quantum-safe proof verifier is now live on BCH chipnet - and the entire thing fits in a single ~10 KB input.

In plain English:

This is a tiny on-chain program that can verify a mathematical proof is correct… and it’s designed so that even future quantum… https://t.co/SI9q6TKAog
