Not long ago, BNB Chain announced the launch of opBNB testnet, an Ethereum Virtual Machine (EVM)-compatible L2 scalability solution based on the Optimism OP Stack. opBNB greatly improves the scalability of L1 to reduce network congestion and network fees while maintaining a similar level of security as L1.
The following is an introduction to the opBNB testnet from the BNB Chain official blog, translated by Odaily.
The opBNB testnet will be launched on June 19, 2023! We call on testnet validators and dApp builders to try the testnet and provide feedback.
What is opBNB?
opBNB is BSC’s answer to the scalability challenges that limit mass adoption of blockchain technology. As a layer 2 network compatible with the Ethereum Virtual Machine (EVM), the opBNB solution is based on the Optimism OP Stack to further enhance BSC’s scalability while maintaining affordability and security.
The combination of BSC’s powerful capabilities and opBNB-specific new features, including making data access easier, improving the cache system, and adjusting the submission process algorithm to allow simultaneous operations (also known as batching), enables OpBNB to increase the Gas limit to an astonishing 100M, a big leap from Optimism’s 30M. Thanks to these new features, OpBNB can process more than 4,000 transfer transactions per second and keep the average transaction cost below $0.005.
Why is opBNB important?
By leveraging the power of Optimistic Rollups, opBNB moves computation and state storage off-chain, alleviating network congestion and reducing transaction costs. Transactions are executed off-chain, but their data can be published to the mainnet as call data. This revolutionary approach enables a high-throughput environment with low gas fees.
Benefits for projects and developers
With opBNB, developers have access to a powerful and EVM-compatible platform that allows for the creation of an open ecosystem. The opBNB team has made significant contributions to the Optimism Stack to support the expansion of Layer 2 solutions. Leveraging this stack simplifies the process for EVM developers to move their applications to BSC, which can help them reach more users.
Enhanced Scalability: As mentioned earlier, opBNB can support over 4,000 transfers per second. All of this is possible due to opbnb’s innovations, which consist of improvements in data accessibility, optimizations in the cache layer, and adjustments to the submission process algorithm to allow for simultaneous operations (also known as batching). This is a significant improvement over BSC’s current capacity, making it ideal for applications with a large number of daily active users.
EVM compatibility: Compatibility with EVM means opBNB provides an accessible platform for developers familiar with Ethereum tools and dApps. This compatibility simplifies the migration or expansion of existing Ethereum applications to BSC, providing a wider audience and resources. Developers can take advantage of this to make the most of the Ethereum and BNB Smart Chain ecosystems.
Future-proof development: The blockchain space is evolving rapidly, and staying adaptable is key to continued growth. With opBNB’s powerful and flexible framework, developers can easily adapt to changes, add new features, and experiment with innovative ideas. This makes opBNB not just a solution for now, but a strategic choice for the future.
OpBNB has the potential to foster the growth of a wide range of applications, from gaming dApps to social networks, thanks to the efficient and cost-effective blockchain environment it provides.
Let's build together
The launch of opBNB marks the beginning of a new chapter in our journey to create a scalable, accessible, and cost-effective blockchain ecosystem. However, this is just the beginning.
Together, let’s harness the power of opBNB to create an efficient, scalable, and sustainable blockchain ecosystem. The future is optimistic, and we’re excited to shape it with you. Join the testnet launch on June 19th and start building on opBNB today!
