A VTXO, or Virtual Transaction Output, is a data structure in the Ark protocol representing a transaction output with a lifecycle from creation to settlement or expiration. It differs from a Note by tracking specific state transitions and round-to-VTXO relationships.
VTXO state management includes Created, Settled, Spent, Swept, and Unrolled states. These states reflect specific lifecycle phases, indicating whether the virtual transaction output is newly generated, confirmed, utilized, or expired.
To debug an unspendable VTXO, identify its current state—Created, Settled, Spent, Swept, or Unrolled. Analyzing the VTXO lifecycle and event types reveals the specific reasons behind the behavior and why the virtual transaction output remains blocked.
VTXO data models are represented in Go for server-side and TypeScript for client-side implementations. These models define the domain attributes, storage mechanisms, and spending paths required for interacting with the Ark protocol's virtual transaction outputs.
The distinction between a VTXO and a Note lies in their data structures and lifecycle management. VTXOs involve detailed state management and tree construction, whereas Notes serve a different representational purpose within the Ark protocol's ecosystem.
A VTXO expires after a predefined lifecycle duration, transitioning to the Unrolled state. During unrolling, the virtual transaction output is removed from the virtual state, its underlying tree construction is settled on-chain, and its spending paths become invalid.
