Aptos vs Arbitrum

Architecture and execution

Aptos is listed as a Layer 1 network and uses a non-EVM execution environment. Arbitrum is listed as a Layer 2 network and is EVM-compatible.

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

Capacity and confirmation cadence

Aptos lists the higher published capacity: 160,000 TPS.

Aptos lists the shorter block time: 0.5s.

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

Aptos lists the lower reference fee: $0.000001.

Aptos lists a 7% staking-reward rate in this reference dataset. Arbitrum has no 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: Aptos is not EVM-compatible, while Arbitrum is.
• 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.
