ISO 23257 — Reference Architecture

FeedOracle six-layer architecture is informed by ISO 23257 concepts for DLT system design, adapted for sustainability data infrastructure.

ISO 23257 ConceptFeedOracle Component
Data LayerLayer 1: Raw Data Collection (CCRI, on-chain sources)
Processing LayerLayer 2: Indicators (normalization, aggregation)
Application LayerLayer 3: Disclosure APIs (MiCA, CSRD, ESG formats)
Consensus/AnchoringLayer 4: DAP Protocol (Merkle roots, on-chain proof)
Asset LayerLayer 1.5: RWA Context (Real World Asset mapping)
Record LayerLayer 5: NFT Layer (Access Passes, Attestation Records)
