Blockchain is a huge database distributed in thousands of different devices known as nodes that collect and store information in a shared and decentralized manner. In this way, a unique record is created but that in turn generates synchronized copies, which makes it impossible to manipulate the data.  In logistic field, the blockchain allows the creation of decentralized platforms with which the history of a product, the manufacturing process and the logistics chain might be traced in detail, increasing transparency and strengthening trust and collaboration between all the actors involved.

Thanks to blockchain it is possible to carry out all the monitoring of the logistic chain, guaranteeing the origins and avoiding the corruptibility of the system. The interesting thing is that this monitoring might be done in the following way:

• Automatic: Dispense of intermediaries, thanks to the use of peer networks.
• Solid: Decentralized and public.
• Secure: The data is encrypted. Authenticity and transparency guarantee the immutability of information.

For its part, these are the benefits:

• Safe of time and money, because system inefficiencies, paper documentation, and manual processes disappear.
• More confidence and transparency between suppliers, customers, collaborators, and clients, since any information that is to be modified in the chain of blocks must be agreed by all.

Point-to-point traceability of the value chain for all participants.
