To sign a message, they reveal a preimage for one hash in each pair, choosing the preimage to reveal based on a bit of the message. A signature verifier re-hashes the message and preimages to ensure ...

NIST finalized the first three PQC standards in August 2024. NSS compliance deadlines start January 2027. Learn what ML-KEM, ...

Quantum computers still look like lab toys: Racks of hardware, error-prone qubits and almost no real-world applications. Yet if you check the roadmaps of major layer-1 blockchains, a new priority now ...

The rise of quantum computing poses both promise and peril for modern cryptography—and blockchains lie right at the crossroads. As machines become capable of shattering our current cryptographic ...

Quantum-resistant tokens use advanced cryptographic methods to protect against the powerful capabilities of quantum computers. Quantum-resistant tokens are a new generation of cryptocurrencies built ...

A breakdown by Andrew Poelstra on how Lamport Signatures, a hash based signature scheme, can be used to create a global state that any Bitcoin transaction can reference to settle smart contracts.

The last six months or so have seen several proposals for improvements to Bitcoin Script: CAT, 64-bit arithmetic, as well as some older ideas (CTV) and far-future ideas (Chialisp and Simplicity). This ...

Solana has launched Winternitz Vault, an innovative security layer to secure the blockchain against quantum computing threats. The vault implements a hash-based signature model that generates new keys ...

Blockstream Research deploys post-quantum signature verification on Liquid mainnet, protecting real Bitcoin assets from future quantum computer attacks.
