Ethereum removes Poseidon in quantum security update

• Ethereum developers removed Poseidon from layer-1 plans as part of a post-quantum security update.
• The change affects the network’s approach to future cryptographic upgrades.
• Developers are continuing work on quantum-resistant security measures.

Ethereum (CRYPTO:ETH) developers removed Poseidon from the network’s layer-1 roadmap as part of a post-quantum security update.

The decision changes Ethereum’s approach to future cryptographic upgrades and network security planning.

Developers said the change is part of ongoing work to improve long-term security against future quantum computing risks.

The update focuses on cryptographic design choices that could affect future Ethereum protocol upgrades.

The decision does not mean quantum computers currently threaten Ethereum’s network security.

Ethereum developers have been researching quantum-resistant cryptography as part of longer-term protocol planning.

The update highlights increasing attention on future security risks across blockchain networks and digital asset infrastructure.
