The developers of Binance’s BNB Chain have just made official the arrival of opBNB on its mainnet. Layer 2, based on Optimism’s OP Stack, has been designed to increase the scalability of the BNB Chain while reducing its transaction costs. An overview of opBNB, which has officially entered the Layer 2 ecosystem
The BNB Chain unveils the opBNB
The teams in charge of developing the BNB Chain have just announced the official deployment of opBNB on its mainnet. First announced at the end of June 2022, opBNB has been built to improve the scalability of the BNB Chain and to offer drastically reduced transaction costs.
As with Base, the layer 2 developed by Coinbase that has been in the news since its launch thanks in particular to the friend.tech application, opBNB is built on Optimism’s OP Stack, a kit that defines itself as a ‘common good’ for the Optimism ecosystem and therefore for the Ethereum ecosystem. Its current version, Bedrock, allows developers to easily launch blockchains based on Optimistic Rollups technology.
Today, we’re launching the opBNB mainnet!
Our Layer 2 solution is now fully released to the public, allowing for lightning-fast transactions and super-low fees! ⚡

Today we are launching the opBNB core network! Our Layer 2 solution is now fully public, enabling ultra-fast transactions and extremely low fees!”
According to the NBB Chain press release, the opBNB testnet period began on 19 June 2023 and has seen more than 35 million transactions pass through the network, across 436,000 unique addresses. At the same time, the opBNB ecosystem was able to accommodate more than 150 decentralised applications (dApps).
In terms of speed and efficiency, the opBNB network processed an average of 86,000 blocks daily, with a block finalisation time of around one second, for a range of daily transactions of between 100,000 and 150,000. The press release also states that the blockchain was able to exceed and process a peak of more than 4,000 transactions per second (TPS). Transaction fees are said to have been reduced to just $0.005 per transaction.
Finally, in terms of security, the data processed by opBNB is submitted to the BNB Chain (its layer 1) for verification by the network’s full nodes. Of course, like the BNB Chain, opBNB is compatible with the Ethereum Virtual Machine (EVM).
What does the future hold for opBNB?
According to the roadmap unveiled by the developers of the BNB Chain, the opBNB network should a priori follow a path towards maximum decentralisation. In order to democratise adoption of the network, opBNB should be enhanced with account abstraction in the near future.
OpBNB should also eventually be compatible with BNB Greenfield, the third blockchain in the BNB Chain ecosystem, which aims to decentralise its data transparently for users and decentralised applications. Considered a priority, this integration should encourage developers to create applications on opBNB.

Other things are also planned to improve network performance. For the time being, and in order to attract new users, the NBB Chain has stated that airdrops will soon be carried out on around fifteen projects in the ecosystem
