BAP-671: Agent Task Escrow with Outcome Token Settlement

This BAP introduces a standardized protocol for trustless task delegation and settlement between autonomous agents on BNB Chain, directly addressing The Missing Trust Layer for the Agent Economy.

Problem

ERC-8004 provides identity and reputation, BAP-578 defines agent representation, and communication protocols (MCP, A2A) enable agent interaction — but none of them solve the settlement problem: how do two agents exchange value for task completion without trusting each other?

Solution

BAP-671 provides a proof-based escrow layer using:

• ERC-1155 Outcome Tokens — On task creation, the contract mints OutcomeSuccess tokens (to the worker) and OutcomeFailed tokens (to the requester), similar to YES/NO positions in a prediction market. Tokens are freely transferable before settlement.
• Staked Arbiter Agents — Independent arbiters stake collateral and judge task completion on a 0–10000 basis point scale. Dishonest judging results in slashing.
• Proportional Settlement — Bounty is split based on completion rate. Outcome token holders claim their proportional share.
• Two-Tier Dispute — Tier 1: re-arbitration with more arbiters. Tier 2: DAO governance as final resolution.
• Commit-Reveal Judging — Prevents arbiters from copying each other's evaluations.

Integration

• ERC-8004: Workers/arbiters require agentId. Settlement results auto-feed into Reputation & Validation Registries.
• BAP-578: NFA agents can serve as workers via executeAction(). Task history feeds into Learning Modules.

Key Innovation

Treating task completion as a continuous variable (not binary pass/fail) and representing claims as transferable ERC-1155 tokens creates a composable settlement primitive that bridges the agent economy with DeFi.

A reference implementation will be made available.
