How Blockchain can do privacy

The design of any digital platform for trade facilitation using Blockchain technology must be done so as to store and transmit data in a way that safeguards the right of individuals to confidentiality and privacy. To achieve this, it may be necessary for developers to only record hashes of personal data on the Blockchain(or perhaps even only a hash of the data’s location/address) and to not store any private data on the Blockchain. Instead, private data can be stored off-chain and only exchanged as needed and in peer-to-peer communications.
