Data & Oracles · Design record
Signed data and private oracles
Use external prices, events, and institutional facts while limiting disclosure of query identity and protected source data according to the access model.

Target business outcome
Financial logic bound to attributable, time-stamped facts with a defined trust, fallback, and dispute model.
Gateway implementation layer
Translate the workflow into a deployable operating boundary.
The record defines the financial problem. Gateway then maps the relevant Platform capabilities, privacy fit, deployment, specialist dependencies, and validation path.
Open Privacy Suite applicability
Source data stays private; only the verified outcome is shared.
Deployment
Close to authoritative sources with independent telemetry export.

- Key management

Actors
- Data provider
- Oracle operator
- Institution
- Application or contract
- Auditor
- Market supervisor
Confidential data
- Query pattern
- Subscriber identity
- Source dataset
- Proprietary transformation
- Trading intent inferred from use
Public or shared evidence
- Signed value or commitment
- Timestamp and source identity
- Aggregation or quorum result
- Fallback and dispute state
Regulator and auditor access
Auditors can verify source, signing, transformation, and delivery evidence while end users receive only the data permitted by licence and policy.
Institutional constraints
- Signing proves origin, not truth
- Query privacy requires transport and access controls
- Fallbacks can create inconsistent state
- Data licensing may restrict replication
Viable approaches
Signed first-party feed
Deliver attributable facts directly from the authoritative source.
Aggregated oracle network
Combine sources under a documented quorum, deviation, and fallback policy.
Private delivery boundary
Limit query and source-data exposure through governed endpoints or cryptographic privacy.
Questions to resolve during discovery
- What source is authoritative?
- How stale can a fact become?
- Who can trigger a fallback or pause?
- Must query identity be hidden from the provider or only other participants?
Relevant standards and frameworks
- Data licensing terms
- Financial benchmark governance where applicable
- Signed-data and key-management policy
- Audit evidence requirements
