Our take
The Ethereum blockchain has seen a surge in activity over the past year or so - but, much to users' frustration, its transaction volume has failed to scale accordingly, leading to hefty gas fees and slow transaction times. Offchain Labs is one of a few players developing Layer 2 rollup solutions, and its Arbitrum rollup has gathered substantial momentum and support in a relatively short time.
Offchain Labs’ Arbitrum claims to offer all the benefits of a rollup - less costly, more efficient - without compromising on security. It is, at the time of writing, the only scaling solution for Ethereum that has working fraud proofs, and at the end of 2021 was dominating the layer 2 rollup market share.
This kind of high-profile and superior efficacy determines a successful blockchain technology. With Offchain Labs’ leadership pedigree and its string of acquisitions, it’s no surprise the company is leading rollup innovation efforts. This sector, however, moves at lightning speed—and the competing ZK rollups are by no means out of the picture just yet.
