Aptos developers have proposed AIP-137 to add optional post-quantum signatures, aiming to prepare the network for future quantum-related cryptographic risks.

Bitcoin’s Taproot usage is declining, signaling wider concerns around its quantum future, as the leading cryptographers race to solve the quantum threat in 2026. A small but growing group of Bitcoin ...

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.

Attackers are recording, and sometimes forging, vast volumes of human communication. Some of this communication is protected by cryptographic systems such as the Rivest–Shamir–Adleman (RSA) system and ...

Data integrity vendor Guardtime hopes its newly announced protocol will replace RSA for the purposes of authentication and digital signatures, touting it as easier to manage and less vulnerable to ...
