Data stored on the blockchain is generally considered incorruptible. [3] Every node in a decentralized system has a copy of the blockchain. Data quality is maintained by massive database replication [42] and computational trust. No centralized "official" copy exists and no user is "trusted" more than any other. [41]
Centralization is an obstacle in typical data-storage systems. [8] When individuals deposit money, a third party intermediary is necessary. [8] When sending money to another user, individuals must trust that a third party will complete this task. [8] Blockchain decreases the need for this trust in a central authority.

The token is a reference (i.e. identifier) that maps back to the sensitive data through a tokenization system.
