Ethereum targets quantum resistance by 2029 starting with Hegotá

Vitalik Buterin isn't waiting for a hypothetical supercomputer to break the network. The Ethereum roadmap now puts a hard deadline on quantum security, aiming for a fully shielded Layer 1 by 2029. The process kicks off with the Hegotá upgrade, which focuses on hardening the chain's foundations through native account abstraction and improved censorship resistance. Developers are pivoting to new cryptographic signatures that can withstand attacks from future quantum hardware. It's a race against physics that requires rewriting how every wallet and smart contract operates. While the threat feels distant, the transition to post-quantum cryptography takes years of testing to avoid catastrophic bugs. This shift moves Ethereum away from traditional elliptic curve signatures toward hash-based alternatives. Will the rest of the industry follow suit before the first quantum threat goes live?
