What Is opBNB? BNB’s Optimistic Layer 2 Rollup
What Is opBNB?
opBNB is a Layer 2 scaling solution for the BNB Chain. It is built on the OP Stack, and will offer users faster and cheaper transactions through optimistic rollups.
Key Takeaways
opBNB is an optimistic rollup network built to scale BSC. It is meant to take the bulk of the workload away from the mainnet and enable the whole network to perform better against increased demand. It uses a sequencer for transactions and a Batcher to package them into batches.
opBNB network attempts to achieve high throughput without sacrificing security by contracting the main network (BSC) for the final validation of transactions performed on its execution layer. A verifier is used to ensure the integrity of these transactions.
opBNB mainnet has launched after spending over a month in the testing phase, with the network will be gradually opened to the general public.
Characteristics of opBNB
Here are some features of the opBNB network:
Scalability
Layer 1 blcohchain like BSC and Ethereum handle all the core functions of blockchain operations (execution, consensus, settlement, data availability) at the network level. This means that there is a risk of network congestion during peak periods or spike in traffic, which results in high transaction fees, slow transactions, and poor user experience.
Layer 2 networks are an execution layer built on top of the main network to enable scalability, offering users lower fees and faster transactions. In the case of opBNB, it utilizes optimistic rollups, where transactions that take place on opBNB are rolled up into a single transaction before being submitted to BNB.
Interoperability As opBNB is built on the OP Stack, it is interoperable with other Layer 2 platforms that utilize the OP Stack, such as Optimism and potentially Base. Moreover, opBNB’s EVM compatibility and support for Solidity helps to create an open and collaborative system across other OP chains, driving innovation.
