• The BNB Chain’s core development team has officially launched opBNB on the public mainnet, a Layer 2 network.

• OpBNB leverages Optimism’s OP Stack to enable developers to deploy Ethereum-compatible decentralized applications on an off-chain layer.

The BNB Chain’s core development team has officially announced the launch of opBNB on the public mainnet. OpBNB is a Layer 2 network with the primary objective of enhancing the scalability of decentralized applications within the BNB Chain ecosystem.

The development team built OpBNB using Optimism’s software package, OP Stack. This Layer 2 scaling solution empowers developers to deploy Ethereum-compatible decentralized applications on an off-chain layer. BNB Smart Chain (BSC) subsequently secures these applications using optimistic roll-up technology. The primary objective is to boost transaction speeds and lower fees for decentralized applications.

The opBNB platform is said to have successfully managed more than 35 million on-chain transactions and witnessed the deployment of over 150 decentralized applications (DApps) on its testnet. Furthermore, BNB Smart Chain asserts that the platform reached a maximum throughput of 4,000 transactions per second during a rigorous stress test to assess its performance.

Optimistic Rollups for Transaction Scaling

opBNB, built upon the Optimism OP Stack, boasts compatibility with the Ethereum Virtual Machine (EVM). This compatibility enables opBNB to seamlessly engage with Ethereum-based smart contracts networks and adhere to ERC-20 token standards.

This solution utilizes optimistic rollups to enhance transaction scalability by assuming that transaction data, once proven off-chain, remains valid unless proven otherwise. While this technology has played a crucial role in facilitating the growth of the Ethereum network, critics often point out the inconvenience of having funds locked up for a week during the validation process.

Optimism has experienced substantial growth in terms of daily transaction volumes and an increasing number of active daily addresses. These trends suggest that the layer-2 solution continues to deliver significant benefits to users and decentralized applications (DApps).

Numerous prominent decentralized finance (DeFi) protocols have also implemented Optimism to leverage their scaling capabilities. This list includes well-known platforms such as Uniswap, Aave, 1inch Network, SushiSwap, and Curve Finance.

During June, the team initiated the opBNB testnet, followed by a controlled mainnet release in August, exclusively accessible to a handpicked group of infrastructure providers. Today marks the culmination of this phased deployment, as opBNB is now officially available to the public following its launch.

opBNB completes its testing phase.

Arno Bauer, the senior solution architect at BNB Chain stated.

“Scalability and security remain the paramount priorities for opBNB. Before opening the mainnet to the general public, strict criteria were met,”

opBNB is an integral component of the broader BNB Chain ecosystem, which comprises five distinct networks. These include the BNB Smart Chain (BSC), functioning as a Layer 1 blockchain compatible with the Ethereum Virtual Machine (EVM); Layer-2 solutions opBNB and zkBNB; the BNB Beacon Chain, which plays a central role in staking and governance within the ecosystem; and the data storage network known as BNB Greenfield.
