#EthereumFoundationDropsPoseidonForL1
The Ethereum Foundation ($ETH) has officially abandoned the Poseidon hash function for its future Layer 1 (L1) roadmap, opting instead to return to battle-tested traditional cryptographic hashes like SHA-256 and BLAKE2s.Announced by core researcher Justin Drake on August 13, 2026, this massive architectural shift pivots away from an eight-year, multi-million dollar research bet. The decision serves as a foundational step toward hardcoded post-quantum security and a streamlined "Lean Ethereum" execution architecture.⚙️ Why the Mindset FlippedHistorically, developers believed that to make Zero-Knowledge (ZK) cryptography efficient, the blockchain needed a "SNARK-friendly hash". This led to the creation of Poseidon in 2019, which used complex prime-field math to remain cheap inside ZK proof circuits.$NVDAB $GOOGL.US
