Renewable energy certificate registry
RECON checks every renewable energy certificate against plant physics, statistics and its trading history — then records it on-chain so the same generation can never be sold twice.
The signal triangle
A single model can be gamed. Three methods that share no inputs are much harder to fool at once — so every certificate is examined by all three, and fused into one composite confidence.
Could this plant have produced it?
Solar position is computed for the plant's exact coordinates and the claim's exact minute. Clear-sky irradiance and nameplate capacity set a hard ceiling — a claim above it is not a statistical outlier, it's impossible.
Does it look like honest generation?
An anomaly model scores every claim against its plant's own history and its regional peers — stepped output cliffs, digit distributions that drift from Benford's law, volumes no peer produces.
Where does the energy end up?
Certificates are traced from generator to holder. Flagged energy pooling in one wallet across many plants, or looping back to an issuer's affiliate, surfaces as a topology finding.
From meter to mint
STAGE 01 / 05
Generation
A plant reports what it produced.
Plant ID, energy generated, source, and the exact date and time of generation -- the raw claim everything else is checked against.
STAGE 02 / 05
AI analysis
Scored for fraud risk in real time.
An ML model checks the claim against the plant's physical capacity, its trading graph, and weather history, returning a 0-100 fraud score with plain-English reasoning -- not a black box.
STAGE 03 / 05
Certificate composed
Plant data, score, and reasoning become one record.
Everything that doesn't need a blockchain's guarantee -- plant details, the fraud score, the AI's reasoning -- lives here, off-chain, where it can be explained, updated, and queried.
STAGE 04 / 05
Minted on-chain
One claim goes to Ethereum: this is unique.
The smart contract checks the (plant, energy, timestamp) triple against every certificate it has ever minted. If it's already been used, the mint reverts -- on-chain, unconditionally.
STAGE 05 / 05
Verified
Anyone can check it, no account needed.
A public verify page reads the chain directly for proof of uniqueness, and the database for the reasoning behind it -- two different guarantees, shown as two different things.

The one idea that matters
On-chain · Sepolia · ERC-721
Proven uniqueness
This exact generation record — this plant, this energy amount, this timestamp — has never been minted into a certificate before. Nothing else. The contract enforces it unconditionally; no one, including us, can override it.
require(!isRecordUsed(plantId, energyMWh, generationTimestamp))
Off-chain · explainable
Explained evidence
Plant details, the fraud score and the reasoning behind it live in a database, not the chain — because that data needs to be readable, queryable and correctable, not just tamper-proof. Only the uniqueness claim needed a blockchain.
