Privacy and blockchain

Privacy and blockchain means that information about what you do can be recorded in a special kind of computer list called a blockchain, which is like an online record book that is used to keep track of what happens. Data written into the blockchain is secure and can't be changed, so it is a safe way to store important information. With blockchain, your personal data is kept private and secure, only you have access to it, so no one else can see or know what you have done.
