Background and Problem
Limits of ownership-centric markets
A hardware sale with a closed service contract does not create a liquid market for tasks. Opaque SLAs hinder price discovery and utilization. Without open settlement, small operators cannot credibly market capacity or obtain finance against future cash flows
Consensus primitives
Proof-of-Work prices energy [1]
; Proof-of-Stake prices collateral and punishment risk [2]
. Neither binds ledger updates to physical actions. Oracles bridge off-chain facts [3]
, but few define adversarially testable schemas for trajectory-bound, sensor-rich evidence. Morph uses Ethereum for final settlement [2]
, oracle attestations, and on-chain governance
Need for Proof-of-Physical-Work
PoPW must:
Bind job-specific actions to cryptographic commitments.
Support third-party re-evaluation and challenges.
Allow deterministic resolution with transparent incentives.
Preserve privacy through commitments and selective disclosure.
We assume untrusted networks, partial hardware compromise, and rational adversaries with bounded budgets.
