Buterin Unveils Lean Ethereum Roadmap with Ambitious Throughput Targets

Vitalik Buterin has outlined the next phase of Ethereum's development, dubbed 'Lean Ethereum', which will span the next three to four years. The roadmap focuses on achieving several long-term goals for the base layer, including faster L1 finality, gigagas L1 throughput, teragas L2 scaling, post-quantum cryptographic security, and private L1 transfers.

The Lean Ethereum plan is a multi-year effort that will roll out through staged protocol changes. It is not a single network upgrade, but rather a broad phase of protocol development. Buterin's update describes the roadmap as a 'work-in-progress coordination tool', not a locked schedule, and notes that timing should be treated with caution.

One key aspect of Lean Ethereum is the integration of recursive STARKs into the verification model. This will allow for proof-based verification, where complex computation can be proven once and verified more efficiently by the network. The roadmap also puts post-quantum security and privacy at the forefront, aiming to replace cryptographic assumptions that could become vulnerable to quantum computers.
