Documents & extended metadata are assembled and stored in a structured folder tree in a vault on XDEX. This encrypted, secure digital vault stores information for each entity, asset, and transaction.

As each document and metadata record is added to the vault, it is hashed and added to the index of the vault contents. When vault contents are finalized, the vault admin permanently locks the record, which is hashed and recorded on the ledger.

The encrypted binaries and hashes are permanently logged to the distributed ledger as a secure, immutable data record.
