Blockchaintechnology is based on an innovative use of cryptography and has attracted a lot of attentiondue to its characteristics, which include:

The creation of data records that are permanent (i.e. cannot be changed or deleted); The ability to identify the time and origin of every entry in a Blockchain; The collaborative potential providing access to data in a Blockchain to multiple participants; The guaranteed implementation of smart contracts (programmes) that automatically execute once a set of agreed conditions are met.
