Execution Framework

Why our execution framework starts with Arbitrum Orbit and the key technical benefits it provides

Our choice of Arbitrum Orbit as a rollup framework is driven by five key technical advantages that enhance performance, flexibility, and user experience.

  1. Fast Block Times
  2. Superior Latency Performance
  3. Built-in Customizability
  4. Stylus WASM Environment
  5. Bridging Infrastructure

Fast Block Times

Arbitrum Orbit enables significantly faster transaction processing compared to competitors through fast block times, providing a clear performance advantage for users and applications.

  • Recommended minimum: 250 milliseconds
  • Achievable range: 100-150 milliseconds (with caution)
  • Not recommended: Below 100ms, strongly discouraged at 50ms

Superior Latency Performance

Faster transaction receipts, which is what users actually perceive and care about. Block times help for internal chain operations, but end-to-end transaction receipts is what users see/feel.

End-to-end transaction latency: Arbitrum Orbit latency tends to be around one second (1/2 to 1/3 of OP Stack's latency).

Built-in Customizability

Arbitrum Orbit has been designed from the ground up as a customizable foundation. Key customisable components:

  • Custom gas tokens: Full support (notably, Optimism has discontinued this feature)
  • Sequencing layer: More flexible than OP Stack since it is a more decoupled component from the rest of the tech
  • Precompiles: Easy integration and support

Stylus WASM Environment

Arbitrum Orbit's Stylus WASM environment offers significant flexibility for contract development, enabling new possibilities beyond traditional EVM-based chains.

  • Language support: Write contracts in Rust alongside Solidity
  • Computational advantage: Rust contracts can handle much more complex computation than Solidity alone. (It doesn't increase storage capabilities, but it does increase computation capabilities)
  • Use case: Enables functionality that would be impossible or impractical in pure Solidity (e.g. complex, fully onchain NFT metadata generation, advanced cryptography functions like TEE attestation verification)

Bridging Infrastructure

  • Native bridge UI: All Arbitrum chains can leverage the same familiar bridge interface
  • User benefit: Users interact with a bridge they already know and trust
  • Withdrawal management: Flexible options for handling withdrawals (Learn more about how Syndicate handles withdrawals)

Summary

Arbitrum Orbit provides a robust, high-performance foundation with the flexibility we need for customization while maintaining excellent user experience through fast transactions and familiar bridging interfaces.
