Tierion is a technology company that built infrastructure for anchoring data to public blockchains to create verifiable, timestamped proofs. Founded in 2015 and based in Hartford, Connecticut, Tierion developed tools that allowed organizations to create cryptographic proofs that data existed at a specific point in time, without revealing the underlying data itself.

The company created Chainpoint, an open standard for anchoring data to the Bitcoin blockchain. Chainpoint works by hashing data and aggregating those hashes into a Merkle tree, then recording the root hash in a Bitcoin transaction. This allows millions of data points to be verified against a single blockchain entry, making the process scalable and cost-efficient. The Chainpoint standard has been adopted by various organizations for use cases including document verification, audit trails, and regulatory compliance.

Tierion also launched the TNT token as part of its Chainpoint Network, a distributed system of nodes that process and verify proofs. The company raised venture capital from investors including Digital Currency Group and Blockchain Capital. Tierion's work on verifiable data proofs represents foundational infrastructure in the broader movement to use public blockchains as trust anchors for enterprise and institutional data integrity.
