How Blockchain Anchoring Works

Blockchain anchoring is the highest level of evidence integrity Borderly offers. It takes a summary (called a Merkle root) of your records and publishes it to the Polygon blockchain — a public, permanent, immutable ledger. Blockchain anchors are created exclusively for Certify subscribers and included in their reports and verification portals.

Borderly does not put your personal data on the blockchain. Instead, it publishes a cryptographic summary (the Merkle root of your hash chain) that anyone can use to verify your records without seeing them. Think of it as publishing a fingerprint of your records on a permanent public bulletin board.

Certify reports include a blockchain transaction reference. Anyone can look up this transaction on a public blockchain explorer to confirm that the fingerprint matches your records.
