First-order effects

• Exchanges and custodians gain an external benchmark against which their storage practices can be judged — and BitGo, which sells multisig security services, positions its own approach as the reference implementation.
• High-profile Bitcoin breaches stop being treated as isolated bad luck and become arguments for standardized practice across every company holding customer keys.

Second-order effects

• Rival custodians face a choice: adopt the proposed standards publicly or explain why they won't, turning a voluntary document into a competitive credential much like the ratings framework the major exchanges later built for themselves.
• Industry-authored security norms give future regulators something to codify — IOSCO's eventual custody provisions could draw on exactly this kind of groundwork rather than starting from scratch.

Third-order effects

• If the pattern holds, self-regulation becomes crypto's staging area: private standards arrive first, then harden into certification regimes — the path consumer IoT followed when the Connectivity Standards Alliance turned vendor practices into a globally recognized cybersecurity certification.
• The longer arc runs toward security expectations being set by whoever writes the standards first, which shapes how the industry later confronts even structural threats like the quantum-computer risk to Bitcoin's underlying code.
