A corporate archive is private. SX4 can run offline. Hence no documents ever travel on the net when archived, ensuring complete confidentiality. It is then your choice to make its hashed inventory accessible online in a few seconds. Once hashed, the content of the archive cannot be accessed but any of its documents can be searched, and located instantly. As to the archive, it cannot be tempered with as all documents are made blocks and tied in a chain. The beauty of the blockchain technology.
