Written by Daniel Lumi Arbitrum’s New Architecture Ethereum has long faced scalability challenges that have hindered its ability to handle the ever-growing demand for decentralized applications. As the leading and most secure smart contract platform, Ethereum’s main bottleneck has always been its ability to process transactions quickly and at a low cost without compromising on its inherent security. To address these limitations, various L2 solutions have emerged, with Arbitrum standing out as the most successful and widely adopted rollup in the Ethereum ecosystem.
