The Ethereum Foundation is changing its approach to post-quantum security. New advances in compact proofs mean the Poseidon cryptographic hash function is no longer the preferred choice. This shift aims to strengthen Ethereum against future quantum computer attacks.
The Ethereum Foundation is updating its strategy for protecting the network from quantum computers. Previously, the Poseidon cryptographic hash function was a key part of this plan due to its strong performance. However, recent breakthroughs in what are called 'compact proofs' have made Poseidon less ideal. Researcher Justin Drake noted that these new proof systems now offer better efficiency. This means the Foundation is exploring other options to ensure Ethereum remains secure even as quantum computing technology develops. The goal is to make sure the blockchain can resist attacks from powerful future computers.
