Tierion

Tierion works by creating a proof that links data to a transaction on a blockchain. This is called anchoring. Anyone with this proof can verify the data’s integrity and timestamp without relying on a trusted authority.

- Chainpoint uses a highly scalable architecture that is designed to generate millions of proofs per second. - Chainpoint includes time data from Network Time Protocol (NTP) servers and the National Institute of Standards and Technology (NIST) with anchors to the Bitcoin and Ethereum blockchains, allowing Chainpoint proofs to simultaneously possess accurate and trustless time attestations. - Chainpoint responds immediately when a hash is submitted. Proofs are automatically upgraded as they are anchored to the Bitcoin and Ethereum blockchains. - Chainpoint periodically anchors into the decentralized Bitcoin and Ethereum blockchains. This allows the Chainpoint proofs to inherit the security properties of multiple blockchains. - Chainpoint’s scalability makes it cost-effective for the world to anchor data to a secure public blockchain. This is particularly relevant as Bitcoin transaction fees have increased more than 100x in the past two years and are likely to continue to rise. ​- Chainpoint servers work in consensus to generate a global, publicly auditable, blockchain called the Chainpoint Calendar. This makes it easier to verify Chainpoint proofs and audit the network.
