Anatomy of a Bark VTXO
summary
Bark stores spendable units as VTXO on disk inside a per-app SQLite DB; each VTXO is a leaf in a round Taproot transaction funded by a coordinator (captain) and verifiable by a co-signature/RPC bundle. Payments within the same arc move VTXO balances instantly with 0% intra-arc fees, outbound spends forfeit the genesis chain to the server which performs an atomic swap, VTXOs have a 28-day expiry and are refreshed via hash-locked swaps.
