BNB Chain has announced the release of the opBNB testnet, a new Ethereum Virtual Machine (EVM)-compatible blockchain based on Optimism's OP Stack. opBNB is a high-performance layer-2 solution within the BNB ecosystem, built using the OP Stack.
According to the developers, the new blockchain is expected to achieve speeds of 4,000 transactions per second (tps) at a cost of 0.005 U.S. cents per transaction.
This is twice as fast as BNB Chain and significantly faster than Ethereum's 30 tps. The opBNB testnet is expected to provide developers with the opportunity to test applications and complex tools before deploying them on a mainnet.
The OP Stack is the standardized, shared, and open-source development stack that is maintained by the Optimism Collective.
