Ethereum Researcher Proposes Accelerating Post-Quantum Transition to December 2028

Ethereum Foundation researcher Justin Drake proposed completing Ethereum's comprehensive post-quantum and post-AI transition by December 2028, speaking at Devcon 8 in Mumbai. The aspirational target sits one year ahead of the Ethereum Foundation's official December 2029 deadline. Achieving the 2028 goal would require developers to ship three major network upgrades across a 24-month window following an early 2027 milestone, deploying production-ready leanVM technology and hash-based signatures like leanSPHINCS. The proactive timeline aims to protect network infrastructure where roughly 72% of total ETH supply currently sits in addresses with exposed public keys.
