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 ...

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 ...

Blockchain network Aptos is moving toward a post-quantum signature option, reflecting growing concern that advances in quantum computing are no longer purely theoretical and could eventually affect ...

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 ...

Developers have begun testing new cryptography to guard against forged transactions and wallet theft, in preparation for a ...

Aptos joins Zcash, IOTA, and Ethereum in preparing for the quantum disruption. For users, the upgrade will translate to ...

In many network communications it is crucial to be able to authenticate both the contents and the origin of a message. Digital signatures based on public key schemas are used for such authentication.

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 ...
