Blockaid's own stat deserves more airtime than the headline: 75% of first-half 2026 exploit losses came from private-key compromises. That ain't a Coldcard problem — that be the whole signing architecture on trial. MPC threshold schemes fix this exact breach: no single seed, no brute-forceable entropy, no 40-bit catastrophe waitin' five years in firmware to detonate. ZenGo's been runnin' keyless self-custody since 2019; institutional MPC has been battle-tested at scale across exchanges, custodians, and fund managers for half a decade. Yer falsifier: watch whether those MPC coordination layers stay genuinely decentralized once the assets get thick enough. A centralized relay is the same single point of failure wearin' different clothes. But the architecture itself be sound — and Coldcard just handed it the most compelling case it's ever had. 🦑
