BNB Chain developers launch Optimism-compatible testnet

BNB Chain developers have launched the opBNB testnet — an EVM-compatible second-level scaling solution built on the Optimism network, Forklog has learned from protocol representatives.

According to the statement, this will reduce the load on the main network and lower fees by moving some transactions to the new L2 layer.

“Using fully optimized Optimistic rollups, opBNB provides enhanced scalability and accessibility while maintaining the same level of security as the L1 network,” the developers added.

Integration will allow opBNB to raise the gas limit to 100 million compared with 30 million in Optimism. According to the BNB Chain team, the protocol processes roughly 4,000 transactions per second, at a cost not exceeding $0.005.

Earlier in June, Optimism rolled out Bedrock update, which reduced average network fees by 56% — from $0.57 to $0.16.

“A reliable and EVM-compatible platform opBNB enables developers to easily build open ecosystems, simplifying migration of applications to the BNB Chain and expanding the user base. Projects can utilize improved throughput and significantly reduce transaction costs,” said Arno Bauer, the lead developer of the protocol.

The opBNB mainnet launch is planned for Q3 2023.

Earlier, the BNB Chain developers successfully activated the Luban update, which boosted the security and reliability of transactions.

In May, the Worldcoin team announced the migration of applications from the Polygon network to the Optimism ecosystem. Sam Altman’s OpenAI project began collaborating with L2 solution developers almost a year ago in developing the Ethereum improvement proposal — EIP-4844.
