If someone wants to cheat, they will cheat via blockchain. If you want to know that the data is correct, you have to test it - for example by making stocktaking, or random spot checks. Otherwise, someone can write on blockchain that they sold 10000 hamburgers, while in reality they sold none. As for your example of "10 restaurants" - it seems that you have very poor knowledge of ERP systems and concepts like MRP https://en.wikipedia.org/wiki/Material_requirements_planning https://en.wikipedia.org/wiki/Material_requirements_planning Might as well start here: https://en.wikipedia.org/wiki/Supply_chain_management https://en.wikipedia.org/wiki/Supply_chain_management Companies have been using databases to collect information about their resources since their inception. You have a very naive view when you think that "databases have to be moved to the cloud", when in reality companies have been using own servers that collected data from shops since the 1980s if not earlier. If you really think that storing data in one database is some new concept, or you think that basic MRP for 10 restaurants is impossible.. then maybe read a bit about supply chain management. Those concepts are not new at all; tons of tools help with that, since last ~30 years, if not more. Bitcoin is not even useful in this scenario; because if 1 restaurant fat fingers something into blockchain, then this error sits there forever, while in a classic database, someone can usually correct it in an easier way. And people make mistakes all the time.
