The overview section introduces CPHAR's positioning, scope, and terminology. Read these pages before the protocol details as they establish the distinction between physical-state evidence and reserve accounting that the rest of the documentation relies on.
Overview
What CPHAR is, what it proves, what it does not prove, and the vocabulary used throughout the documentation.
What is CPHAR?
An introduction to CPHAR, a protocol pattern for proving claims about physical commodity reserves with hardware-backed seal attestation and verifiable reserve accounting.
DraftWhat Problem Does CPHAR Solve?
The attestation gap between periodic audits and the role CPHAR plays in providing continuous cryptographic evidence of physical reserve integrity.
DraftWhat CPHAR Proves
How CPHAR separates physical-state evidence from reserve accounting, and what each layer is and is not designed to prove.
DraftWhat CPHAR Does Not Prove
The explicit non-goals of CPHAR are claims that hardware-attested sealing cannot, by itself, support.
DraftTerminology
Key terms used throughout CPHAR documentation.
