Fuel Quality Assurance Layer

Test at every stage.
Trace adulteration to source.

Deploy a fuel quality monitoring network from refinery to pump where adulteration is detectable at any stage, surprise test results are on-chain and immutable, and supply is suspended automatically on a quality failure. When a test detects adulteration, on-chain records trace it to the distributor who mixed kerosene after depot dispatch, with court-ready evidence.

The Foundation

The Execution Mechanics

Turn infrequent paper testing into a refinery-to-pump quality chain that traces adulteration to its source.

01.

End-to-End Quality Chain

The Traceability Ledger follows fuel from refinery to pump, so a quality reading at any stage attaches to the same batch record and adulteration is detectable anywhere.

02.

Immutable Test Results

The Quality and Recall Ledger anchors each surprise test result on-chain, so an adulteration finding cannot be altered or lost.

03.

Device-Attested Sampling

The Device Attestation module signs each test from a verified device, so a result is bound to a genuine instrument rather than a paper form.

04.

Source Tracing

Because custody is recorded at each hop, a failed test traces adulteration to the exact custodian, such as a distributor who mixed kerosene after dispatch.

05.

Automatic Supply Suspension

A quality failure automatically suspends supply from the implicated point, stopping adulterated fuel from moving further down the chain.

06.

Court-Ready Evidence

The sealed test and custody records form court-ready evidence, supporting enforcement against adulteration and subsidy leakage.

The Fuel Quality Lifecycle

Follow a single fuel batch from refinery dispatch through a surprise pump test to source tracing and suspension.

Smart Contract Anatomy

Cerulea decomposes fuel quality monitoring into modular contracts. Each layer anchors the batch, records custody, seals device-attested tests, and traces adulteration to source.

Applicability Across the Spectrum

Refinery-to-pump quality monitoring is a horizontal capability. Here is how different actors in fuel retail put the shared ledger to work.

Oil Marketing Companies

Monitor fuel quality from refinery to pump and suspend supply on failure, protecting brand integrity and cutting subsidy leakage with adulteration traceable to source.

Network & Execution Architecture

Whether you are bridging depot and distribution systems or capturing tests from attested field devices, Cerulea routes both into one quality ledger.

Track A: Distribution System Bridging

For companies on legacy depot and distribution systems. Custody events are translated into signed on-chain batch records through the API gateway.

Technical Methodology

The legacy timeline reflects supply chain integrity integration benchmarks. Wiring distribution systems, building custom quality and tracing logic, and shipping device-attested testing for an average network takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your quality and custody rules into pre-audited WebAssembly binaries and provisions the quality ledger instantly.
