Copyright and file Integrity

A Trustworthy Distributed Platform for Copyright Registration and File Integrity Verification. On top of Ethereum.

What is Engraved?

Engraved is blockchain technology built on top of Ethereum with two main goals. First, provide a permanent, secure and cheap mechanism to establish indelible records which relate original works with their copyright holders. This relation is built through customizable copyright licenses on a certain moment in time. The original work is not stored on the blockchain but a cryptographic digest of it, allowing the copyright holder to keep its work in secret if desired. Second, Engraved also constitutes a system for file integrity verification, where file distributors can register files with their checksums under a custom namespace if desired.
