One-time source authorization
The producer registers, accepts the current agreement and shares the plant through the supported manufacturer application. VSE never asks for a partner wallet.
VSE connects producer data, immutable evidence, verified available energy, restricted blockchain retirement and machine-verifiable final proof.
Raw manufacturer responses are stored before calculations. Every interval, unit, sale and retirement receives deterministic hashes and an auditable event trail.
The producer registers, accepts the current agreement and shares the plant through the supported manufacturer application. VSE never asks for a partner wallet.
The original API payload is written to restricted evidence storage and fingerprinted with SHA-256 before any normalization or energy calculation occurs.
Plant, device, logger, timestamps, completeness and sample gaps are validated. Duplicate source intervals are rejected by database and contract invariants.
Each verification event includes the previous event hash, canonical payload, UTC timestamp and deterministic event hash.
VSE reserves a verified available unit only through a unique order. Retirement is blocked until the linked buyer invoice is recorded as PAID.
Scoped APIs can retain submitted workload declarations. Trusted measurement, independent validation and automatic matching are not activated; these records do not create verified energy or CO2 credits.
After blockchain confirmation, the final envelope can contain source, audit, methodology, sale and beneficiary hashes, chain transactions and an Ed25519 signature.
