Architecture and execution

Optimism is listed as a Layer 2 network and is EVM-compatible. Ethereum is listed as a Layer 1 network and is EVM-compatible.

Their consensus entries also differ: Optimism lists Optimistic rollup, while Ethereum lists PoS. That distinction describes how each network is designed; it is not a standalone quality score.

Capacity and confirmation cadence

Optimism lists the higher published capacity: 4,000 TPS.

Optimism lists the shorter block time: 2s.

Published capacity and block-time figures are useful reference points, but they are not equivalent to observed throughput, finality, or application-specific performance. Evaluate the workload, settlement requirements, and tooling before drawing a conclusion.

Costs and participation

Optimism lists the lower reference fee: $0.14.

Optimism has no staking-reward rate in this reference dataset. Ethereum lists a 3.31% staking-reward rate in this reference dataset.

Fees and reward rates can change with network conditions and policy. Treat the entries here as a comparable snapshot, not as live pricing or a return forecast.

How to assess the trade-off

  • Start with execution compatibility: Both networks share the same EVM compatibility status.
  • Then compare the reference values that matter to the application: capacity, block time, and transaction fee.
  • Finally, review each network’s documentation, security model, ecosystem, and current operating conditions before deploying capital or production software.
