The opBNB network is the Layer 2 scaling solution for the BNB Smart Chain(BSC) powered by bedrock version of Optimism OP Stack.
Besides the differentiators of bedrock, opBNB is the solution that we aim to provide the best optimistic rollup solution on the BSC.
| Parameter | opBNB value | Optimism value | Ethereum value (for reference) |
|---|---|---|---|
| Block gas limit | 100,000,000 gas | 30,000,000 gas | 30,000,000 gas |
| Block gas target | 50,000,000 | 5,000,000 gas | 15,000,000 gas |
| EIP-1559 elasticity multiplier | 2 | 6 | 2 |
| EIP-1559 denominator | 8 | 50 | 8 |
| Maximum base fee increase (per block) | 12.5% | 10% | 12.5% |
| Maximum base fee decrease (per block) | 12.5% | 2% | 12.5% |
| Block time in seconds | 1 | 2 | 12 |
