Ethereum layer 2 zkEVM ‘Scroll’ announces mainnet launch

According to Etherscan blockchain data, Scroll’s mainnet was activated a little more than a week ago. Scroll, a new zero-knowledge Ethereum Virtual Machine (zkEVM) aiming to improve blockchain scalability, officially announced the launch of its mainnet.

The Scroll team made this announcement in a post dated October 17, emphasizing that existing applications and developer toolkits on the Ethereum network can now seamlessly migrate to this new scaling solution. They emphasized that “everything functions right out of the box.”

Scroll’s zkEVM solution is designed to deliver lower transaction costs and higher throughput for decentralized applications running on the Ethereum network. It achieves this by aggregating thousands of transactions off-chain into a single batch and subsequently submitting a proof that consists of a concise data summary to Ethereum’s mainnet.

Based on Etherscan statistics, Scroll quietly launched its mainnet on October 8, coinciding with the deployment of the first smart contract on the mainnet.

Scroll revealed that this mainnet launch followed a rigorous 15-month period of testing and security audits, conducted across three distinct testnets. The project’s bridge and rollup contracts were subjected to audits by OpenZeppelin and Zellic, while its zkEVM circuits underwent reviews by Trail of Bits, Zellic, and Kalos.

During the testing phase across the three testnets, over 450,000 smart contracts were deployed, enabling more than 90 million transactions across 9 million blocks. Additionally, the firm generated 280,000 ZK-proofs.

About a month ago, Scroll’s co-founder, Ye Zhang, explained that the project would initially launch with centralized features but had plans to gradually decentralize. He mentioned, “We will have a centralized sequencer and the central approver button,” but added that there was a roadmap to remove that centralization.

Zhang also mentioned that the Scroll team intends to propose several ideas for community discussion to determine the best path forward for Scroll.

Scroll, founded in 2021, aims to foster a more community-driven approach. Other zkEVM solutions striving to scale Ethereum include Polygon, zkSync, StarkWare, and Immutable.

Jordi Baylina, the technical lead of Polygon Hermez zkEVM, expressed to Cointelegraph that competition in the zkEVM space will ultimately bolster the Ethereum ecosystem. He stated, “Having different projects adds a lot of experience, and it’s also a way to test different approaches, ways of handling things, or ways of solving things.”
