Blockchains provide a transparent and immutable way of storing data.
They are the perfect tool for storing financial transactions, health records, and any other information that needs to be both highly secure and easily accessible to anyone with the right permissions.
Blockchain databases aren't stored in any single location (hence the block), which means there's no one central point of attack, so it provides a cryptographically-secured system.
It also has great scalability; we can add more storage space without compromising on speed or security.
In addition, blockchains offer something called smart contracts, which are computer protocols that facilitate, verify, or enforce the negotiation or performance of a contract without third parties.
