Ethereum Foundation abandons the Poseidon hash for L1, switching to SHA-2 or BLAKE. Binary-field proof systems let standard hash functions match Poseidon speeds. A production leanVM is penciled in for ...

Quantum computing will reshape encryption, but not overnight, and a disciplined, phased approach lets organizations modernize cryptographic foundations without disruption while strengthening security ...

Ripple ex-CTO David Schwartz says Bitcoin miners who double spend risk a fork that turns ASICs into space heaters.

BIP-110 Bitcoin fork stalled after two blocks on August 8-9, 2026, but backers have escalated to a proof-of-work change that ...

QCIM architecture runs algorithms underpinning three NIST PQC standards in a TSMC 28-nanometer design environment ...

Modern internet security relies heavily on mathematical problems that ordinary computers cannot solve within a useful time. A ...

Bitcoin's mining and ledger are built on SHA-256, a hash function that quantum computers cannot efficiently break. That means nobody, not even someone with a sufficiently powerful quantum computer, ...

Post-quantum encryption candidate HAWK collapsed July 29 after Anthropic AI found a fatal mathematical flaw in 60 hours, while South Korean firm ITCEN PNS announced KCMVP certification for EdgeCrypto ...

SHA-256 is a cryptographic hash function developed by the NSA in 2001 that converts any input into a fixed 256-bit output, serving as the foundation of Bitcoin’s proof-of-work consensus mechanism.
