Consensus

consortium

"consensus-agnostic"

  • Arbitrum uses and refers to consensus as 'verifiers' that assumes the existence of a consensus mechanism, including a...

    • single centralized publisher,
    • a quorum-based consensus system,
    • or Nakamoto consensus as used in Bitcoin
  • Verifier: "global entity or distributed protocol"

Efficency

Arbitrum’s VM architecture makes dispute resolution very efficient.

Even if parties behave counter to their incentives, Arbitrum verifiers can efficiently adjudicate disputes about contract behavior without needing to examine the execution of more than one instruction by the contract.

Max TPS

Up To 4,500 transactions per second

Additional Info

  • Compatible with Ethereum, Solidity Smart Contract code is comipled with Arbitrum
  • Only verifies digital signatures instead of every part of the contract for the VM
