Chain / On-Chain
Separate public fields, private evidence, administrative data, disputed records, identity controls, and audience-specific views before a record becomes public or externally accessible.
Disclosure boundaries decide what becomes public, what remains private, and what can be shown only to approved parties. OCO separates identity, evidence, administrative notes, public fields, dispute state, and verification metadata before exposing records. That prevents transparency systems from leaking sensitive data while still giving the intended audience enough information to trust the record process.
Approach
Chain or on-chain infrastructure is used only when the use case justifies a durable evidence layer. OCO begins by separating truth of the original input from proof of submission, approval, timestamp, change history, or disclosure state. Governance, input controls, reviewable records, and clear user explanation carry the trust model. The chain layer then becomes one part of a broader evidence system: useful when it strengthens accountability, avoided when a normal database, audit log, or private record is the better engineering choice.
Scope
OCO uses chain or on-chain infrastructure when a data product needs durable records, verification paths, public accountability, or alteration-detectable change history.
Tamper-evident evidence and transparency records.
A chain record does not make an original claim true by itself. It makes records, changes, approvals, and evidence trails harder to alter without detection when governance, input controls, and review paths are defined.
