Chainpoint is an open standard for creating a timestamp proof of any data, file, or process. Anchor an unlimited amount of data to the Bitcoin blockchain. Verify the integrity and existence of data without relying on a trusted third-party.
Chainpoint links a hash of your data to a blockchain and returns a timestamp proof. A Chainpoint Node receives hashes which are aggregated together using a Merkle tree. The root of this tree is published in a Bitcoin transaction. The final Chainpoint proof defines a set of operations that cryptographically link your data to the Bitcoin blockchain.
A Chainpoint proof contains the information to verify that the hash of some data is anchored to a blockchain. It proves the data existed at time it was anchored. Chainpoint proofs can be verified without reliance on a trusted third party.
