During the most recent meeting of Ethereum consensus layer developers, leanVM was showcased. This innovative virtual machine is crafted to manage zero-knowledge proofs (ZKP) and safeguard the network against the threats posed by quantum computing.

leanVM is designed to serve as a crucial element in significantly lowering scaling expenses and enhancing recursion speed. The project’s creator indicated that the current processing time is 2.7 seconds on a CPU, with aspirations for a tenfold enhancement. A vital aim of leanVM is to proficiently handle post-quantum algorithms. Rather than merely validating single XMSS signatures, the new virtual machine will facilitate recursive aggregation, merging thousands of signatures into a singular, concise proof.

Notable attributes of leanVM encompass:

  1. An elementary architecture consisting of only four instructions for the instruction set architecture (ISA), rendering it exceptionally straightforward and conducive to formal verification.
  2. Implementation of multilinear STARKs for quicker and more compact consensus in comparison to traditional methods.
  3. A novel sampling approach that diminishes commitment costs and boosts efficiency.
  4. A complete verifier implementation in roughly 1,000 lines of Python code, streamlining the auditing and testing process.
  5. Validators being capable of operating even on low-end devices like a $7 Raspberry Pi Pico, while aggregators can utilize CPU/GPU resources to achieve high throughput.

The advancement of leanVM is incorporated into Ethereum’s decade-long strategic roadmap, which was revealed last month. The new Lean Ethereum framework will remain consistent with Ethereum’s roadmap but will progress alongside it, without being integrated directly into the mainnet.

In 2025, the Ethereum network experienced the Pectra hard fork, and two significant upgrades — Fusaka and Glamsterdam — are slated for November. Ethereum Co-Founder Vitalik Buterin has previously discussed the transition to a new virtual machine and substantial technical transformations.
