Data Anchoring

What is data anchoring?

Data anchoring consists in building a time-stamped proof of existence for a data by linking it to a tamper resistant and time-stamped blockchain.

A strong cryptographic link between the data and a timestamped transaction in the blockchain is built and saved in a proof receipt. This receipt can be used later on by anyone having the data and an access to the blockchain to prove that the data existed and has not been modified since the transaction's confirmation date.

Woleet's data anchoring implementation relies on the resilience and immutability of the Bitcoin blockchain to provide the best possible security level. The Bitcoin blockchain being publicly accessible, Woleet proofs can be verified without any third party, at anytime, from anywhere.
