A blockchain is a distributed digital ledger that records and stores data in a secure and immutable way. Unlike a traditional database, a blockchain is managed by a network of computers, rather than a single entity. This makes it virtually impossible for malicious actors to alter the data stored within it.
A database is a structured collection of data that is organized and stored electronically. It is typically managed by a single entity and can be updated or changed as needed.
For example, a traditional database may be used to store customer information, such as their name, address, and contact information. This data can be updated or changed as needed.
In contrast, a blockchain could be used to store the same customer information, but in a secure and immutable way. This means that the customer information stored within the blockchain cannot be altered or changed without the consensus of the network.
