System Model and Participants
Time is measured in block numbers and timestamps, acknowledging drift. Off-chain artifacts are content-addressed (IPFS/Arweave). Hashes are collision-resistant. The chain provides ordered, immutable events with probabilistic finality [2].
Participants:
Job Poster: Defines tasks, escrows MORPH, sets acceptance criteria and challenge window Tc.
Robot Agent: Software on-device or in a secure controller; holds keys, collects telemetry, and submits evidence.
Robot Operator: Owns/manages robots; stakes MORPH; bears slashing risk.
Oracle/Verifier: Independent services that evaluate evidence and emit on-chain attestations.
Watcher/Challenger: Any account that monitors and challenges submissions with bonded counter-evidence.
Settlement Contract: On-chain state machine for jobs and funds.
Reputation Registry: On-chain scores for robots and operators; queried by matching and payouts.
