Ethereum’s quantum-era shift to SHA and BLAKE boosts crypto security

Quantum ZeitgeistAugust 15, 20263 min read

The Ethereum Foundation is redirecting its focus from the Poseidon hash function to established cryptographic methods, like SHA and BLAKE, to maintain post-quantum security and dependability. This shift signals a move toward enhanced protection against threats posed by quantum advancements, not just for Ethereum, but for the entire blockchain community.

Ethereum is prioritizing established cryptographic algorithms, SHA and BLAKE, in a shift away from the newer Poseidon hash function, a move intended to bolster post-quantum security for the cryptocurrency platform. Ethereum’s research director, Justin Drake, explains that Poseidon’s advantages have been eclipsed by the rapid evolution of computational proofs and efficiency. This strategic transition is also designed to…
