The BNB Chain blockchain ecosystem will leverage Optimism’s rollup technology to power its newly launched opBNB layer 2 scaling platform.
BNB Chain announced the launch of L2 compatible with the Ethereum Virtual Machine (EVM) on the public mainnet, providing lower gas fees and faster transaction speeds for decentralized applications running in the ecosystem.
The opBNB platform has reportedly processed more than 35 million on-chain transactions and deployed more than 150 DApps on its testnet. BNB Chain also claimed that the platform reached a peak of 4,000 transactions per second during stress testing.

Arno Bauer, senior solution architect at BNB Chain, emphasized that scalability and security are the top priorities for scaling solutions while meeting strict standards:
“This includes high availability, 4K transactions per second, rigorous stress testing, gas cost reduction to under 0.2 gwei, fast final results under 1 second, and enhanced security through multiple external audits.”
As Cointelegraph previously reported, opBNB is based on the Optimism OP Stack and is compatible with the EVM, allowing it to interact with Ethereum-based smart contracts, networks, and ERC-20 token standards.
The solution leverages optimistic aggregation to scale transactions, assuming transaction data that has been proven off-chain is valid unless proven otherwise. The technology is important for helping the Ethereum network scale, but critics highlight that funds in these protocols are locked up for a week while validation checks are processed.
Optimistically, the number of transactions processed daily has grown significantly and the number of daily active addresses continues to increase, indicating that layer 2 solutions continue to provide value to users and DApps.
Many major decentralized finance (DeFi) protocols are also deployed on Optimism to take advantage of its scaling capabilities. These include Uniswap, Aave, 1inch Network, SushiSwap and Curve Finance, among others.
Cointelegraph has reached out to BNB Chain to determine more details on opBNB development and other scaling solutions the ecosystem may consider.
