While Blockchain is an excellent way to streamline supply chain operations, it also has downsides. Because supply chain information is confidential, private, and sensitive, a blockchain with no permission system can cause leak data.
However, a permissioned blockchain system is also less secure because it has fewer nodes, risking the decentralization feature of the technology. Although supply chain companies believe that no one can change data on the Blockchain, intentional misconduct or human error can cause data inaccuracy.
Moreover, blockchain solutions for supply chains may slowly process transactions more than conventional databases. The reason is that the technology validates the data on various computers and services.
Similarly, a permissionless blockchain solution is expensive, considering the high volume of transactions in the supply chain. Remember, you will have to pay the transaction fees every time you need miner nodes to create blocks on the network.
