What is opBNB?
opBNB relies on OP Stack’s bedrock technology, enhancing node performance and ensuring EVM compatibility. Its goal is to enrich the Binance ecosystem by enhancing the BNB Smart Chain’s overall performance and user experience.
The opBNB network acts as the Layer 2 scaling solution for the BNB Smart Chain, powered by Optimism OP Stack’s foundational version. It offloads transaction processing and resource usage from the BNB Smart Chain while preserving data integrity on the mainnet. Users can seamlessly interact with the opBNB network by depositing funds from BSC and utilizing various applications and contracts.
How Does opBNB Work?
OpBNB operates through a meticulous process:
- Transaction Submission: Users initiate transactions sent to an Optimistic Rollups contract on the BNB Smart Chain.
- Transaction Pooling: The Optimistic Rollup contract consolidates transactions into a single unit.
- Main Chain Validation: The consolidated transaction is transmitted to the main chain for validation.
- Blockchain Commitment: The main chain validates and commits the transaction to the blockchain ledger.
- Contract Status Update: Following validation and commitment, the Optimistic Rollups contract updates its status, ensuring transparency.
Structure
Sequencer
At opBNB’s core lies the Sequencer, transforming diverse transactions into a coherent format and transmitting them to the Roll-Up Contract for processing.
Prover (Node)
The Prover constructs evidence to verify state transitions, ensuring transaction integrity and preventing third-party intrusion.
Verifier (Challenger)
The Verifier rigorously assesses the evidence provided by the Prover, ensuring transactions adhere to network standards.
