On the Road to StarkNet: A Permissionless STARK-Powered L2 ZK-Rollup

On the Road to StarkNet: A Permissionless STARK-Powered L2 ZK-Rollup

Enjoy the security and feel of Ethereum with the scale of a ZK-Rollup

TL;DR

We’re building StarkNet in four steps:

Step 0 — Foundations (completed*) Step I — Planets: Single-App Rollups Step II — Constellations: Multi-App Rollups Step III — Universe: A Decentralized Rollup

We expect to have Step I deployed in a few short months, and be well on our way to Steps II & III by the end of 2021.

Introduction

We’re building StarkNet, a decentralized, permissionless and censorship-resistant STARK-powered L2 ZK-Rollup that supports general-computation over Ethereum. It is based on the Turing-complete Cairo language.

Developers, users and StarkNet nodes will be able to do everything one would expect from a permissionless L2 Rollup: Developers may build applications implementing their own business logic and deploy them on StarkNet. Users may send transactions to StarkNet to be executed, just like they interact with Ethereum today. StarkNet nodes and participants will be crypto-economically incentivized to ensure the network operates efficiently and fairly.

All StarkNet transactions will be periodically batched, and their validity will be proven in a STARK proof, to be verified on Ethereum. As the computational effort required to verify STARK proofs is exponentially small compared to the computation proven, StarkNet will scale Ethereum by orders of magnitude.

Since all StarkNet state transitions will be STARK-proven, only valid ones will be accepted on Ethereum. All data required to reconstruct the full StarkNet state will be published on-chain. Anyone will be able to run their own StarkNet node. These properties will make StarkNet as secure and permissionless as Ethereum.

We’ve been at it for three years, and have already achieved some remarkable milestones in turning “Moon Math” into production-grade and efficient software running on Ethereu...
