F-Procure

Architecture

A five-layer reference architecture designed to add verifiable evidence to existing procurement environments — with sensitive data kept off-chain.

Reference architecture

The five layers

Compliance layerConfigurable governance and jurisdiction mapping
AI-assisted analyticsHuman-reviewed exception and anomaly detection
ERP interoperabilityIntegration with existing enterprise systems
Smart contractsConsistent workflow and policy controls
Blockchain layerTamper-evident event registration

The five layers of the F-Procure reference architecture, from governance configuration down to tamper-evident registration.

Research implementation

What the published MVP demonstrated

The peer-reviewed F-Procure paper implemented the framework as a minimum viable prototype on the Flare Network's Coston2 and Songbird test environments, used as technical testbeds rather than as platforms under evaluation.

Tender creation encoded and traced through smart contracts
Sealed-bid commit–reveal, keeping bids secret until deadlines
Award and escrow execution with multi-phase contract lifecycles
Verifiable on-chain audit trails for each workflow event
Procedural requirements (deadlines, documentation flags) expressed as programmable conditions
A minimal anomaly-detection layer flagging irregular bidding patterns for human review

These evaluations used small-scale, manually executed synthetic scenarios designed to test correctness rather than throughput. No statistically generalisable performance benchmarks are reported. See the published paper for the full scope and limitations.

System context

Alongside your systems of record

Existing systems of record

ERP
Sourcing
Vendor Management
Contract Management
Audit

F-Procure assurance layer

Evidence registration
Policy controls
Verification
Exception analysis
Audit package

Existing enterprise applications remain the systems of record. F-Procure provides an additional evidence, assurance, and verification layer.

Privacy and data model

The off-chain / on-chain boundary

Remains off-chain

Bid and tender documents
Contracts and commercial terms
Personal data
Due-diligence reports
Internal deliberations

May be registered for verification

Cryptographic hashes of documents
Timestamps of selected events
References and identifiers
Status attestations
Proofs of workflow steps

Sensitive documents remain off-chain. Only selected hashes, timestamps, references, statuses, or proofs may be recorded — subject to data-minimisation and jurisdictional review.

Pilot architecture must be reviewed against the participating organisation's policies and legal obligations. F-Procure does not make absolute privacy, security, regulatory, or legal-compliance guarantees.
