The proposed sequence includes Glamsterdam, Hegotá and the provisionally named I* and J* forks, in response to Ethereum developer-tooling lead 0xRahul’s account of the presentation. Convention attendee Bob Summerwill recognized J* because the proposed post-quantum endpoint.

The sooner post-quantum workforce roadmap says L1 protocol upgrades may very well be accomplished by 2029, with full execution-layer migration taking extra years. Its printed sequence locations a validator key registry at I, signature-verification options at J, consensus proofs and leanVM at L, and post-quantum blob dealing with at M.
Drake’s proposed J* endpoint would subsequently carry protocol-wide safety into an earlier fork. It’s a purpose, not an agreed activation schedule: the Strawmap describes itself as a piece in progress fairly than a prediction, and the post-quantum workforce says remaining upgrades are decided by means of Ethereum’s open governance processes.
From Roadmap to Operating Code
A key part is leanVM, a minimal proof-generating digital machine meant to make bigger post-quantum signatures sensible by aggregating their verification. Its public codebase contains implementations and benchmarks for validator signatures, consumer signatures and knowledge availability.
The Basis stated leanVM had been “formally-verified end-to-end” within the previous few days. Nevertheless, the code repository nonetheless labels formal verification “in progress” and warns that leanVM will not be but manufacturing prepared. The linked verification challenge additionally says no proof-system declare has landed and lists end-to-end theorems amongst its assurance objectives.
For holders, a protocol improve and migration of an present account stay completely different steps. As The Defiant beforehand reported, verifying different signatures in a sensible contract doesn’t robotically take away an present account’s authentic signing key’s authority.
EIP-8141, a proposed native path to programmable transaction authorization and post-quantum signatures, stays labeled Draft. It might let account code outline validation fairly than requiring at the moment’s elliptic-curve authentication.
