What is the difference between blockchain and traditional databases?

The main difference between blockchain and traditional databases is the way they store and manage data. In a traditional database, data is stored in a centralized location, which makes it vulnerable to hacking or data manipulation. On the other hand, a blockchain is a distributed ledger that stores data across a network of computers, making it much more secure and resistant to hacking.

In a traditional database, there is typically one central authority that has control over the data, which can make it easier for malicious actors to tamper with the data. In contrast, a blockchain is designed to be decentralized, meaning that there is no central authority controlling the data. Instead, each computer in the network maintains a copy of the blockchain and verifies transactions independently.

Another key difference is that in a traditional database, data can be easily modified or deleted, while in a blockchain, once data is recorded on the ledger, it cannot be altered or deleted without the agreement of the entire network. This makes blockchains much more secure and reliable for certain types of data, such as financial transactions, where data integrity is crucial.

Overall, the key difference between blockchain and traditional databases is the way they store and manage data, with blockchains being more secure, transparent, and resistant to tampering than traditional databases.
