The power of blockchain goes beyond the security it provides. It is about the transparency and peace of mind that it provides through immutability. Every single transaction, whether that transaction is creating new assets on the blockchain or deleting from the blockchain, is recorded and hashed.
IBM’s “Create a fair-trade supply network” code pattern shows you how to digitize the paperwork and documents that are part of the supply chain. Each step of the supply chain is recorded as a different function, in which the participant will submit the relevant data. Once the data is submitted, it is recorded on the blockchain, and will be available to whomever has access to it.
