ZkBoost: Proof Supply Chain Abstraction

The proof supply chain is the process by which Layer 2 networks and ZK applications can generate proofs. Gevulot largely kicked off the proving network craze in early 2024 when it released a v1 design for a permissionless prover network and a functional test network (Try the Gevulot devnet here).

Since then, many other projects have entered the space, including Fermat Layer, Succinct Labs, and Lagrange. While competition is great for rollups and ultimately benefits end users by driving down costs, it also leads to a lot of fragmentation. We feel that rollups needing to integrate with many prover networks to enjoy the benefits of this competition will lead to poor user experiences and ultimately less adoption for the proof supply chain in general.

The Solution: ZkBoost

ZkBoost is a generic abstraction for outsourced proving. In practice, it is a kind of proxy node that proving services and networks can integrate with, providing a single, standardized API for Layer 2 networks to access all proving options.

This offers Layer 2 networks a simple way to access outsourced proving options and, conversely, provides proving services with a straightforward method to offer their services to Layer 2 networks.

The Call to Action

Gevulot is funding early work on ZkBoost, but our goal is for this to be neutral, open-source software. We invite all Layer 2 networks and proving services alike to join us in architecting and funding this work. Furthermore, we’d love to discuss how this implementation should be governed to ensure neutrality.
