Blockchain – also known as distributed ledger technology – is initially a basic technology that can be used in many different ways. At its core, these are distributed databases consisting of blocks. The individual data sets are linked together by encryption methods and transaction data in such a way that manipulation is impossible. In this way, the blockchain creates trust, even if the client and contractor do not know each other.
This system can be used for numerous applications in retail and logistics, as supply chains and proofs of origin of goods become transparent and trackable. Crowd shipping, i.e. parcel delivery by private individuals, could also be realised with the help of blockchain and provide a solution for the great challenge of the "last mile" in online retail.
