Crypto exchange Binance has announced the launch of the opBNB testnet on the BNB Smart Chain (BSC).
This layer 2 product addresses the scalability issue known as the “blockchain trilemma,” which involves balancing scalability, security, and decentralization.
The BSC is a fully functional Ethereum Virtual Machine chain. To achieve enhanced scalability, opBNB utilizes Optimistic Rollups, a technique that processes transactions off-chain and bundles them for submission to the main chain.
OpBNB employs the Optimism OP Stack for this purpose, which makes data more accessible, improves the cache system, allows simultaneous operations, and reduces the computational burden on the main chain.
According to BNB Chain, opBNB has raised its gas limit to 100 million. Therefore this enables over 4,000 transactions per second with an average transaction cost of less than 0.005 USD.
The fraud-proving system used by opBNB ensures transaction legitimacy and network integrity. However it allows anyone to contest the outcomes of a batched rollup transaction by calculating a fraud-proof.
Identifying fraudulent transactions maintains the network’s integrity, fosters confidence, and encourages greater transparency. BNB Chain sees the launch of the opBNB testnet as a new phase in BSC’s efforts to create a scalable, accessible, and cost-effective blockchain ecosystem.
Therefore, they aim to promote the development of various applications, including gaming apps and social networks, by enabling developers and projects to experiment with opBNB. The testnet went live on June 19, and developer resources are now available.
