Optimism vs Solana

Architecture and execution

Optimism is a Layer 2 network and is EVM-compatible. Solana is a Layer1 network and uses a non-EVM execution environment.

Their consensus mechanisms also differ: Optimism uses Optimistic rollup, while Solana uses PoS + PoH. That distinction describes how each network is designed; it is not a standalone quality score.

Capacity and confirmation cadence

Solana has the higher transaction capacity: 65,000 TPS.

Solana has the shorter block time: 0.4s.

Transaction capacity and block time do not predict observed throughput, finality, or application-specific performance. Evaluate the workload, settlement requirements, and tooling before drawing a conclusion.

Costs and participation

Solana has the lower average transaction fee: $0.00025.

Optimism has no staking rate available. Solana has a 7% staking rate.

Fees and reward rates can change with network conditions and policy. They are not live pricing or a return forecast.

Choose for the workload

• Start with compatibility. Optimism is EVM-compatible, while Solana is not. If your tooling already assumes the EVM, that constraint can matter more than a headline capacity figure.
• Match the workload. Compare the reference values that matter to the application: capacity, block time, and transaction fee. A lower fee is useful only if the network can serve your users reliably.
• Check the conditions. Review each network’s documentation, security model, ecosystem, and current operating conditions before deploying capital or production software. Treat published values as a snapshot, not a promise.

Bottom line: choose the network whose trade-offs fit the job and whose risks you can explain plainly. A comparison is useful when it narrows a decision—not when it manufactures a winner.
