It sounds interesting. I would like to ask you if your method and technology are aimed also to already existent items or just for the new ones. And in the first case: how do you certificate the previous passages in terms of identification and ownership? Thank you!
Both. For already existent items the validates in the network: auction houses, appraisers etc. Can provide attestations and documentation to support the item’s provenance. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)
