PriviCore does not employ Blockchain. The Blockchain is ONLY relevant for us is for Device security and potentially holding one part of the key instead of PriviCore in our Multi-Encryption. Key Management we have in our solution, and you can also connect to external Key Management solutions as well.
Privicore is MS fast through stateless tokenization and Asynchronous policy and voting with Authentication. PS! Blockchain would make it too slow.
