Offchain Labs has developed a suite of scaling solutions for Ethereum. This includes Arbitrum, an Optimistic Rollup, that instantly scales apps, reducing costs and increasing capacity, without sacrificing Ethereum's security. Porting contracts to Arbitrum requires no code changes or downloads since it’s compatible with existing Ethereum developer languages and tooling. Arbitrum today is the leading Ethereum scaling solution with dominant market share including hundreds of apps on the platform and over 40% of all rollup liquidity. Offchain labs also contributes to the Ethereum core protocol with the Prysm consensus client. The Prysm project is a Go implementation of the Ethereum protocol as detailed by its official specification. It contains a full beacon node implementation as well as a validator client for participating in blockchain consensus.
