How verification works

STEP 01

Hash your data

SHA-256 hash generated from your record. Original data never leaves your system.

STEP 02

Build hash chain

Each hash links to the previous. Any tampering breaks the chain instantly.

STEP 03

Anchor to blockchain

Merkle root anchored to Polygon. Immutable, public, permanent.

STEP 04

RFC 3161 timestamp

Trusted timestamp from FreeTSA. Legally admissible under eIDAS and ESIGN Act.
