Ethereum Foundation researcher Justin Drake has put forward December 2028 as a target for completing the network’s post-quantum transition. Cointelegraph reported that Drake spoke at Devcon 8 in Mumbai and described the date as a hope rather than a commitment. “Our hope is that by December 2028 we’ll be able to wrap up the full post-quantum and post-AI transition,” he said.
According to Cointelegraph, Drake told the audience developers have 24 months to deliver three more network upgrades. That is a year earlier than the Foundation’s September roadmap, which set December 2029 for quantum resistance across Ethereum’s execution, consensus and data layers. His remarks do not formally replace that roadmap, which is due for reassessment in January 2027.
The outlet noted that in August Drake outlined a plan for production-ready leanVM technology in 2027, followed by post-quantum deployments across the three layers in 2028. It also recalled that StarkWare CEO Eli Ben-Sasson previously told Cointelegraph the 2029 target was “too late” and warned that deadlines could slip. In October, Starknet’s community backed research into becoming an independent post-quantum layer-1 network.
Quantum computing is a long-term concern for blockchains because it could, in theory, break the signature schemes that protect wallets today. The timetable here is a developer aspiration, and the article does not report any firm schedule for the upgrades or a date when quantum machines might threaten Ethereum.
