The key feature of this electronic register is its distributed data storage. It is stored on a host of networked computers and managed by the participants. The same data chain with the same information is stored on every computer and is constantly synchronised.
So everyone involved shares the same version of the data, which works according to jointly defined rules. There is always only one truth – this feature makes the blockchain uniquely transparent and secure. Remote storage means that the data chain can only be modified if everyone involved agrees. Making tampering virtually impossible.
