Tierion anchors the root of a Merkle Tree made up of all inbound records every 10 minutes into a Bitcoin transaction. With that root in a Bitcoin transaction, you can use a portable cryptographic proof (Tierion calls them blockchain receipts) to validate the integrity of each record at a later point in time.
The Bitcoin blockchain is a global immutable data ledger that makes for a great place to anchor hashes to.
