BNB Chain unveils layer-2 testnet leveraging Optimism’s OP stack

Partnerships
Product updates

  • BNB Chain, the layer-1 blockchain network developed by Binance, has launched the testnet version of its layer-2 scaling solution, opBNB. The testnet is currently in public beta and users can connect to it by downloading the opBNB wallet.

  • opBNB is designed to address network congestion and high fees on the BNB Chain. It is expected to achieve a throughput of 4,000 transactions per second (TPS) at a cost of 0.005 cents per transaction. In comparison, the BNB Chain currently averages around 1,500 TPS and costs approximately USD 0.05 per transaction.

  • Optimism's OP stack, which acts as a layer-2 scaling solution for Ethereum, is used to build opBNB. The testnet is the first significant implementation of Optimism on a non-Ethereum network, and its success could pave the door for Optimism to be adopted by other blockchain networks.
