Less than a quarter Dollar. The registration price is many orders of magnitude lower than a formal registration ($35 to $55 at the U.S. Copyright Office), making it accessible to everyone and for works which were not often registered beyond a copyright notice.
It is fast. Obtaining the receipt of a registration certificate may take several months. However, engraving it takes just a few seconds.
The work can be registered without being showed to a third party. An irreversible cryptographic digest is performed on the work and will act as a PoE (Proof of Existence). However, secure vault IPFS-based storage will be available if all the minimum funding levels are reached during the crowdsale.
4. Time accuracy
The work is recorded in the blockchain associated with the timestamp of the block in which the transaction was recorded, giving greater accuracy.
It works on top of the Ethereum blockchain with more than 25,000 active nodes. As the platform is decentralized, it is less susceptible to catastrophic loss or failure or even hacking.
