Verifier families
The deterministic programs that decide settlement
The deterministic programs that decide settlement. The hub snapshots the verifier ID and codehash at task creation, so later registry changes cannot redirect open tasks.
STATS_V1
Bounded cloud-cost estimation. Deterministic STATS summary against an integerized cost batch.
Verifier ID
0x87964240a746236cc99fb5d3ff344e5110b6429980582b953c2de786a74347b4
REPO_PATCH_HARNESS_V1
Proof-of-Pass Escrow for AI-written code. Patch applies cleanly, declared test command runs, result is pass.

Global economics
Fee and minimum bond
Protocol-wide parameters. Fee in basis points is snapshotted at selection — later fee changes cannot retroactively alter open tasks. Minimum bond enforced at activation.
Global fee
100 bps (1.00%)
Global minimum bond

Deploy transactions
How each contract reached main
Transaction hashes that created each contract. Arbiscan preserves the deploy receipt and the verified source.
