The Ethereum Foundation just made a massive architectural shift on $ETH L1 that most of the market is completely missing. After an 8-year, multi-million dollar research effort into "SNARK-friendly" hash functions like Poseidon, the core team is officially abandoning it in favor of battle-tested traditional hashes like SHA-2 and BLAKE2s. Why this is a monumental upgrade for Ethereum's L1 roadmap: $ETH Breakthrough Proof Speeds Recent advances in binary-field SNARK designs (like Binius) now allow standard, traditional hashes to generate roughly 1 million proofs per second—matching Poseidon's performance without requiring custom cryptography. Hardened Post-Quantum Security Relying on decades-old, battle-tested cryptographic primitives drastically reduces smart contract vulnerability risk compared to newer, specialized hash functions. Lean Layer 1 Infrastructure This shift paves the way for a production-ready leanVM targeted for 2027 and full consensus/execution integration by 2028, positioning Ethereum for ultimate long-term scalability and quantum resistance. Instead of forcing the EVM to adapt to complex zero-knowledge math, ZK technology has finally adapted to traditional computing. Is this architectural pivot a bullish sign for Ethereum's long-term technical moat, or does it slow down immediate scaling? Drop your take below 👇 $ETH #EthereumFoundationDropsPoseidonForL1
