Autonomy Accountability
Moderate autonomy
Jurisdictional Posture
No issuing entity and no jurisdiction of issue: there is no party on whom process can be served to freeze, reverse or reissue a holder balance. Real exposure runs to the holder's own custodian, exchange or fiat ramp, not to an issuer.
Catastrophic Failure Modes
Irrecoverable key loss. Stake-pool concentration allowing coordinated censorship or reorganisation. Ledger-rule bug in a hard-fork combinator event. Quantum key recovery (B6 = 5, joint highest in the index and still low).
