The Ethereum Foundation has decided to move away from using the Poseidon hash function in its post-quantum cryptography plans. This change follows new developments in compact proof technologies that have diminished Poseidon's prior performance benefits.
Researcher Justin Drake highlighted that recent advances in compact proofs effectively erase the performance edge that Poseidon once held, according to CoinTelegraph. This shift reflects the Foundation's ongoing efforts to adapt its cryptographic approach to emerging technological improvements.
For Japanese investors and developers, this update signals Ethereum’s commitment to maintaining robust security measures against future quantum threats, a critical factor as Japan continues to expand its blockchain and crypto infrastructure.
