Offchain Labs, the team behind ethereum’s second layer Arbitrum, has bought out Prysmatic Labs. Preston Van Loon of Prysmatic Labs said:
“These two world class teams are value aligned in their work to scale Ethereum and a close collaboration between Layer 1 and Layer 2 can allow for these technologies to iterate and deliver faster. Scaling Ethereum is more important than ever and this merge will help Ethereum further its impact globally.”
