Summary

Griff Green, a member of the Arbitrum Security Council, said blockchains are often misunderstood as fully immutable systems when they in practice depend on social consensus (community agreement on network rules). He linked that view to his early involvement with The DAO (a 2016 Ethereum-based venture fund run by smart contracts), describing it as his first project. His remarks point to a long-running industry debate over how blockchain networks balance code, governance, and community decision-making during critical events.

Terms & Concepts
  • social consensus: Community agreement on how a blockchain should operate, especially when participants coordinate around upgrades, disputes, or extraordinary events.
  • immutability: The principle that blockchain records cannot easily be changed, though network participants can still coordinate changes under exceptional circumstances.
  • The DAO: A 2016 decentralized autonomous organization (blockchain-based member-run entity) on Ethereum that became a landmark case in crypto governance debates.
