BNB Chain, the world’s largest smart contract blockchain in terms of monthly active users, has launched the opBNB testnet, an Ethereum Virtual Machine (EVM)-compatible L2 chain scalability solution based on Optimism OP Stack to further democratize blockchain technology.
opBNB represents a significant milestone in BNB Chain’s innovation with its ability to move transactions to layer 2, alleviating congestion and reducing transaction costs. Leveraging fully optimized Optimistic Rollups, opBNB achieves enhanced scalability and affordability while maintaining a similar security level as L1. opBNB on BSC achieves a high transaction throughput by leveraging EVM execution optimizations that have been applied and verified on the BSC network. The underlying combination of opBNB innovation, which is composed of the optimization of the data accessibility, caching layer, and adjusting the submission process algorithm to allow simultaneous operations (also known as batcher), enables opBNB to reach a gas limit of up to 100M vs 30M for Optimism (source: link). Based on these comprehensive optimizations, opBNB can support over 4000 transfer transactions per second and an average transaction cost lower than 0.005 USD.
“opBNB is a key driver of BNB Chain’s commitment to delivering a seamless and efficient experience for users, developers, and projects. By providing a low-cost and high-performance infrastructure that aims at mass adoption which provides more flexibility to applications,” Arnaud Bauer, Senior Solution Architect at BNB Chain said.
“opBNB is based on the ethereum Op Stack, where we’ve heavily contributed to the L2 community. We invite the community and dApp builders to try the testnet and contribute to the future of Web3.”
opBNB’s robust and EVM-compatible platform enables developers to easily create open ecosystems, facilitating the migration of applications to BSC and expanding their user base. Projects can leverage improved throughput and significantly lower transaction costs, resulting in a superior user experience. Furthermore, opBNB’s enhanced scalability overcomes challenges previously faced by projects with high transaction volumes on BSC and enables them to thrive.
From enhanced scalability and EVM compatibility to low gas fees and improved end-user experience, the launch of opBNB marks an important step towards creating an accessible and cost-effective blockchain ecosystem. Developers and projects are invited to explore the potential of opBNB, not only to benefit their project but also to enrich the broader BSC ecosystem and shape the future of blockchain technology.
