According to Odaily, BNB Chain has launched a new Layer 2 (L2) blockchain aimed at addressing its scalability challenges. On June 19, BNB Chain unveiled the opBNB testnet, an L2 scaling solution based on the Optimism OP Stack. This new development is expected to enhance the security and scalability of the BNB Chain. The announcement highlighted that opBNB can support over 4,000 transactions per second, with an average transaction cost of less than $0.005. Additionally, opBNB optimizes data accessibility, caching layers, and submission process algorithms to enable simultaneous operations. This allows the gas limit per block to increase from the 30 million allowed by Optimism to 100 million.

However, not everyone is convinced of the efficacy of this new solution. Adam Cochran, a partner at Cinneamhain Ventures, expressed skepticism about the launch of an Optimism fork. He suggested that there are other viable options, such as joining Optimism as a 'superchain,' becoming an Ethereum L2 directly, or even operating as an L3 on Optimism or Arbitrum.
