“organizations that rely on multisigs tend to exhibit the same structural adaptations that blockchain protocols do. They introduce redundancy to reduce liveness risk—more signers, distributed geographically and functionally, echoing how blockchains add more nodes. They create sub-committees and domain-specific quorums, resembling sharding or modular consensus. They adopt escalation paths and emergency powers, mimicking protocol-level upgrade mechanisms. And they begin abstracting signers into roles and agents rather than individuals, just as blockchains move from accounts to smart contracts” https://open.substack.com/pub/npcmemo/p/protocol-review-1-multisig-signing
