Ethereum's Justin Drake sets 2028 target for post-quantum transition

Ethereum researcher Justin Drake has pointed to December 2028 as the target for the network's post-quantum and post-AI transition, describing the date as a "hope" rather than a firm commitment.

Why the date draws attention

Ethereum, like most public blockchains, secures ownership and transfers with elliptic-curve signatures. A sufficiently powerful quantum computer running Shor's algorithm could in theory derive private keys from public ones, which is why developers have spent years exploring signature schemes designed to resist such attacks. No publicly demonstrated machine is currently capable of this.

Drake's stated timeline places the work roughly a year ahead of an earlier target, though the source provided no technical detail on which signature scheme is favoured or how the change would be coordinated across execution and consensus clients.

What is not yet defined

• The 2028 date was framed as an aspiration, not a roadmap commitment
• The source gave no specifics on candidate post-quantum signature schemes
• The "post-AI" component of the transition was not defined
• Delivery depends on client teams, testing and network governance

Ethereum's development roadmap carries several concurrent workstreams, and quantum-resistance research has been discussed publicly for years without a ratified mainnet schedule. The source did not indicate that a formal timeline has been approved, leaving the 2028 goal an expressed target from one researcher rather than an agreed deliverable.
