BNB Chain to expand layer-2 ecosystem with new rollup service

0


BNB Chain, the ecosystem powered by the BNB (BNB) token, has unveiled a rollup service solution for building layer-2 blockchains on its network. 

On March 14, BNB Chain announced its rollup-as-a-service (RaaS) solution to help projects build layer-2 networks on BNB Chain. The service will give projects access to the tech infrastructure required to deploy layer-2 networks on the blockchain, expanding BNB Chain’s ecosystem.

BNB Chain also explained that the service supports decentralized applications (DApps). This allows a wide range of project verticals, including blockchain gaming or decentralized finance, to be deployed on the layer-2 networks. In addition, BNB Chain is also providing rollup management support and a “no-code” deployment option for projects that might not be familiar with coding.

The BNB Chain team explained that the layer-2 networks established through BNB Chain’s RaaS service will be built on the BNB Smart Chain (BSC), which they described as their “foundational layer-1 blockchain and governance chain.”

According to the BNB Chain core development team, the new service follows its goal of supporting the mass adoption of Web3 technology. They said:

“By combining the power of RaaS and the interconnectivity capabilities of our ecosystem, developers will have a comprehensive toolkit to build efficient and scalable layer-2s on BSC.”

BNB Chain has been pouring its efforts into layer-2 networks since 2023. On June 20, 2023, it unveiled its layer-2 scaling solution opBNB — based on the Optimism OP Stack — on a testnet. The layer-2 solution is compatible with Ethereum Virtual Machine, which means it works with Ethereum-based smart contracts and token standards.

On Sept. 13, the scaling platform was deployed onto a mainnet, making opBNB publicly available after a testing phase. BNB Chain reported that the platform handled more than 35 million transactions and 150 DApps deployed on its testnet run. The project also claimed that the opBNB platform hit 4,000 transactions per second (TPS) on a stress test.

According to BNB Chain, the new rollup service is part of its efforts to reach the goals it set earlier this year. On Jan. 31, the firm released its “BNB Chain 2024 Outlook,” which introduces the “One BNB” interconnectivity concept that links BSC and its decentralized storage service, BNB Greenfield.
