BNB Chain introduces opBNB, a Layer 2 scaling solution based on Optimism

BNB Chain has introduced a new L2 blockchain that it hopes will solve its “scalability challenges.” On June 19, BNB Chain released the opBNB testnet. This L2 scaling solution is based on the Optimism OP Stack and is intended to add additional security and scalability to the BNB Chain. According to the announcement, opBNB can support more than 4,000 transfer transactions per second with an average transaction cost of less than $0.005. In addition, opBNB allows for optimization of data accessibility, caching layers, and adjustments to the submission process algorithm to allow for simultaneous operations. This allows it to increase the gas limit per block from 30 million allowed by Optimism to 100 million. Adam Cochran, partner at Cinneamhain Ventures, is one of those who are skeptical of this development, saying that launching an Optimism fork “doesn’t make sense” because there are other options, such as joining Optimism as a “superchain” or directly becoming an Ethereum L2, or even an L3 on Optimism or Arbitrum.
