*5.1.1 Scalability*

Each node within the blockchain network has a complete copy of all the information stored on the blockchain. When a new block is added, the system needs to update the copy at each node so that a single version of truth is ensured among all participants. As the network expands with more members and data, this update process slows down accordingly, and latency becomes an important issue. Agri-food supply

chain involves many actors and generates a very large amount of information every day. In the pilot stage, the latency issue described before may not be pronounced, but this issue will be exacerbated when a blockchain initiative scales up beyond the pilot stage. This is the reason why many supply chain blockchain initiatives remain proof of concept for years [24].
