Ethereum scaling solution Scroll announced Tuesday the launch of its mainnet. The platform aims to provide more cost-effective and quicker transactions on the smart contracts blockchain.
Scroll employs Ethereum Virtual Machine (EVM)-compatible zero-knowledge technology, simplifying the transition for developers moving their applications from Ethereum to its new “zkEVM” network.
Scroll’s zkEVM works by bundling thousands of off-chain transactions into one batch and then providing a brief data summary as proof to Ethereum’s mainnet.
Scroll co-founder Sandy Peng emphasized its impact on ETH scalability, saying, “We can expect Scroll to scale Ethereum by an order of magnitude.”
Etherscan data from last week showed that Scroll’s smart contract had been deployed on October 8, but the Scroll team delayed the official announcement until this week. Its announcement came almost seven months after Polygon and Matter Labs introduced their zkEVMs.
Scroll’s mainnet launch came after successful years of testnets, with over 55 million transactions on Alpha and Beta testnets and nearly a million batches completed on Layer 1. In the most recent testnet, Sepolia, there were over 900,000 wallet addresses and over six million transactions in just two months.
On its three testnets, over 450,000 smart contracts were employed, enabling more than 90 million transactions across nine million blocks. Scroll also created 280,000 ZK-proofs.
“At Scroll, we take security extremely seriously,” said Haichen Shen, co-founder of Scroll.
Shen explained that Scroll prioritizes security, conducting thorough audits with multiple audit firms and opting for an open-source approach on top of having a dedicated internal security team.
The Scroll team mentioned that their bridge and rollup contracts had undergone audits by two blockchain security and auditing firms, OpenZeppelin and Zellic. Additionally, they had their zkEVM circuits reviewed by Trail of Bits, Zellic and KALOS.
Over 100 projects have deployed on Scroll testnets, encompassing infrastructure, DeFi, gaming and more.
Scroll was created in 2021 to build an open-source, scalable ecosystem using zkEVM while preserving Ethereum’s security and the community’s dedication to decentralization. Its roadmap includes milestones like a decentralized prover network and sequencer.
A month ago, Scroll co-founder Ye Zhang mentioned that Scroll would start with centralized features but intends to shift towards decentralization over time.
“We will have a centralized sequencer and the central approver button,” Zhang said.
“We have a roadmap […] To solve the single point of failure and to incentivize the community to build better proving hardware.”
Zhang also mentioned that the Scroll team will propose various ideas for the community to discuss and determine the best path for Scroll’s future.
Furthermore, Scroll’s mainnet will prioritize bringing in infrastructure providers, and then it will gradually enable developers worldwide to create Web3 products.
“We see a future where the vast majority of value transfer takes place on L2s on Ethereum. What will drive that adoption is improved user and developer experience,” said Peng.
“We focus on enabling developers to build blockchain applications that will anchor web3 in real world use cases, attracting new users en masse, and moving everyone forward.”
Over the past years, Scroll has partnered with the Ethereum Foundation’s Privacy and Scaling Explorations (PSE) group, contributing about 50 percent of the PSE zkEVM codebase.
Scroll has also been conducting research to enhance knowledge about zk-circuits, cryptography and hardware acceleration.
