About the company
Offchain Labs is a New York-based company building Arbitrum, a suite of scaling solutions for Ethereum. Arbitrum One and Nova are powered by Nitro, our proprietary technology stack. Nitroās next-generation rollup architecture provides 7x more throughput than Ethereum and lower fees without sacrificing any security. Prysm is an official Ethereum proof-of-stake client written in Go. Both individuals and institutions can use Prysm to participate in Ethereum's decentralized economy by running a node and earn rewards by running a validator to help secure the Ethereum blockchain. Upcoming Stylus will enable users to deploy programs written in popular programming languages like Rust, C, C++, and more, side-by-side with existing Solidity dApps on the same Arbitrum blockchain.
