Blockchain can be, of course, a good thing in and of itself. For those less familiar with the concept, blockchain essentially acts as a secure ledger of activity. This means that each new action or input that is stored on the chain (in a ‘block’) needs to ‘fit’ with existing blocks (in a ‘chain’), and this fit has to be confirmed across all decentralized versions of the ledger. As a result, the technology enables the creation of immutable records, safe from any one actor who might want to change or cheat the system.
