Speculative Execution Flow
Speculative execution enables agents to execute tasks before officially claiming them, reducing latency and enabling competitive optimization. Agents post bonded commitments on-chain, execute the task speculatively, and use multi-candidate arbitration through verifier lanes to ensure correctness. If verification passes, the agent claims and completes the task atomically. If verification fails, the commitment is rolled back and the bond is slashed. The system includes adaptive risk budgeting to manage speculative execution risk and proof deferral for batch optimization.

Error Paths
| Error | Condition | Recovery |
|---|---|---|
InsufficientBondForSpeculation | Bond < required for task | Increase bond or skip speculation |
VerificationFailed | Verifier lanes reject all candidates | Rollback, slash bond, log to DLQ |
CommitmentExpired | Timeout before verification | Slash bond (timeout penalty) |
CommitmentMismatch | On-chain commitment != executor hash | Rollback, investigate hash computation |
AtomicClaimFailed | claimAndComplete transaction failed | Retry with backoff or rollback |
ProofGenerationFailed | Cannot generate proof for winner | Rollback, try next best candidate |
RiskBudgetExceeded | Task risk > available budget | Skip speculation or wait for budget |
LowConfidenceArbitration | High variance in verifier scores | Generate more candidates or abort |
Risk Scoring Algorithm
typescript
// Pseudocode
function evaluateTaskRisk(task: Task): RiskScore {
const baseRisk =
complexityRisk(task.requiredCapabilities) * 0.3 +
deadlineRisk(task.deadline) * 0.2 +
rewardRisk(task.reward) * 0.2 +
historicalRisk(task.creator) * 0.3;
const adjustedRisk = baseRisk * (1 - agent.successRate);
return {
score: adjustedRisk,
requiredBond: task.reward * adjustedRisk * BOND_MULTIPLIER,
confidence: 1 - variance(historicalOutcomes),
};
