What is the difference between a database and a blockchain?
Blockchain is a special type of database management system that has more features than a regular database. We describe some significant differences between a traditional database and a blockchain in the following list :
* Blockchains decentralize control without damaging trust in the existing data. This is not possible in other database systems.
* Companies involved in a transaction cannot share their entire database. But in blockchain networks, each company has its copy of the ledger, and the system automatically maintains consistency between the two ledgers.
* Although in most database systems you can edit or delete data, in blockchain you can only insert data.
