Ethereum L1 to Drop Poseidon for SHA or BLAKE as Quantum-Safe Roadmap Advances Ethereum Foundation researcher Justin Drake said Ethereum's L1 cryptography roadmap will move from Poseidon to traditional hash functions such as SHA or BLAKE. Poseidon is designed for efficient use

What happened

Ethereum Foundation researcher Justin Drake said Ethereum's L1 cryptography roadmap will move from the Poseidon hash function to traditional hash functions such as SHA or BLAKE, as part of advancing a quantum-safe roadmap.

Confirmed

Global impact / market context

This change targets Ethereum's base security layer, aiming to protect it from future quantum computers. For investors, it signals ongoing technical upgrades that could influence confidence in Ethereum's long-term reliability and value.

Analyst inference

Ethereum is a major blockchain network, and its token ETH trades in crypto markets. Technical roadmap updates like this can shape investor sentiment and demand, although the immediate price impact is uncertain without specific market data.

Analyst inference

What to watch

1. Justin Drake's announcement indicates the roadmap direction, but the timeline for implementing SHA or BLAKE and any formal Ethereum Improvement Proposal has not been specified in the article. Confirmed
2. Investors may watch for official Ethereum Foundation communications or developer calls that confirm the exact hash function choice and transition schedule, which could clarify the upgrade's scope and potential network impacts. Proposed
3. A quantum-safe shift could reduce long-term regulatory and technical risks for Ethereum, potentially attracting institutional investors focused on durability, but adoption speed depends on developer consensus and community support. Analyst inference
