The Ethereum Foundation has established a post-quantum security team to address threats from quantum computing. Led by Thomas Coratger, the initiative includes a $1 million Poseidon Prize for enhancing a key hash function and aims to strengthen Ethereum's defenses against potential quantum attacks.

This article discusses a method to improve wallet security by using cryptographic proofs to verify transaction simulations. It aims to eliminate reliance on potentially compromised third-party RPC providers, allowing users to see accurate transaction outcomes before signing. The proposed solution employs Merkle Patricia Trie proofs and multi-node consensus for enhanced trust and verification.
