Run a verified record proving fuel blends meet the mandated biofuel percentage, with traceable sourcing of the biofuel component. Each batch's blending ratio and the origin of its biofuel are anchored as verified records, giving the oil marketing company a defensible compliance certificate for regulatory inspection.
Turn a claimed blend percentage into a verified certificate backed by traceable biofuel sourcing.
01.
Compliance Attestations anchor each batch's biofuel blending ratio, so the mandated percentage is a verified record rather than an unproven claim.
02.
The Traceability Ledger traces the biofuel component to its approved source, proving the blend used an eligible feedstock.
03.
Each blended batch receives a defensible compliance certificate tying its ratio and source together for regulatory inspection.
04.
The biofuel component is checked against the register of approved sources, so a non-compliant feedstock is caught before blending is certified.
05.
The Audit Logs module retains every batch ratio and source, giving the company a tamper-evident record for any inspection or audit.
06.
An inspector queries a batch and sees its verified ratio and sourcing at once, replacing document requests with an on-chain certificate.
Follow a single fuel batch from biofuel sourcing through blend certification to a regulatory inspection.

Cerulea decomposes blending compliance into modular contracts. Each layer sources biofuel, anchors the ratio, certifies the batch, and exposes evidence to inspectors.
Verified blending compliance is a horizontal capability. Here is how different actors in the fuel blending chain put the shared ledger to work.
Prove mandated biofuel percentages per batch with traceable sourcing, holding a defensible compliance certificate for every blend rather than assembling paperwork under inspection.
Key Asset Types
Have their feedstock recorded as an approved source and bound into each blend's compliance record, proving eligibility of the biofuel they supply.
Key Asset Types
Verify blending mandate compliance from anchored ratios and sourcing, confirming eligible feedstock without collecting documents from each company.
Key Asset Types
Whether you are bridging a blending terminal's systems or capturing ratios from a field device, Cerulea routes both into one compliance ledger.
For terminals on legacy blending systems. Ratio and source data is translated into signed on-chain records through the API gateway automatically.

The legacy timeline reflects fuel compliance integration benchmarks. Wiring blending systems, building custom ratio and sourcing logic, and shipping batch certification for an average company takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your ratio and sourcing rules into pre-audited WebAssembly binaries and provisions the compliance ledger instantly.
