Why VeraTrace is fast

Every link is pre-recorded with its processing timestamp — no need to chase down delivery notes.

Every transformation is anchored on the blockchain via a digitally signed attestation: the timeline is legally opposable, not reconstructed after the fact.

RappelConso is ingested automatically four times a day. Matching cross-references GTIN, lot and supplier across four confidence levels.

A single call returns the full cascade of downstream customers impacted, or traces back to the root producers.
