Bytecode’s Ethereum Layer-2 Network Scroll Launches Mainnet

The layer-2 network, Scroll, has officially launched on its mainnet after a successful testnet phase that recorded over seven million transactions from more than 900,000 wallet addresses.

Scroll utilizes zkEVM roll-up technology, enabling efficient proof batching through bytecode-level compatibility. This advancement allows for faster transactions at reduced costs for Ethereum projects that operate directly on the network, as noted by Scroll’s co-founder, Sandy Peng.

In this model, smart contracts retain transaction bytecode on Scroll, which is then validated by a centralized zkEVM node without disclosing the transaction details. Once verified, these transactions are reflected on Ethereum without needing to be re-executed.

The mainnet code of Scroll has been audited by several organizations, including Zellic, Trail of Bits, OpenZeppelin, and KALOS. The Scroll team is currently investigating the development of a decentralized prover network and sequencer to mitigate protocol disruptions and facilitate forced batching during sequencer halts.

At present, upgrades can be executed through a multi-signature wallet overseen by the core team. However, future plans encompass the creation of an SGX-based second prover in collaboration with TEE experts. Additional enhancements are also on the agenda, including a Multi-Prover for Scroll and the formation of a Security Council paired with a delayed upgrade mechanism.
