Blockchain is a chain of blocks. That essentially means that there are a set of blocks linked with each other. Data which is contained in the block is the list of transactions. Simply speaking, set of linked blocks that contain data constitute a Blockchain. Blockchain is definitely a form of database which is maintained by different organizations. This is unlike the traditional database which is maintained only by organization that owns the database. In the traditional database there are replicas or copies which are maintained within the network of the owner organization. On the other hand, in case of Blockchain which is a shared distributed ledger, copies are maintained by different member organizations.
Ownership in case of Blockchain is decentralized i.e. no one person or no one company or organization owns the Blockchain database. But in case of traditional database, ownership is centralized. No one apart
from the owner of the database is allowed to access or make any changes to the database. By the very nature of blockchain, data once written in the blockchain becomes immutable. Consider the example of Bitcoin blockchain. Each block is linked with the other block through the hash. For a block to change, hash needs to change. This is next to impossible. But in case of traditional database, it depends upon the owner organization what data they want to change or what dataset they want to delete.
In case of blockchain any data which is in the form of transaction has to be written based on consensus algorithm. But in case of traditional databases, any kind of data can be written on sole discretion of owner organization. In case of blockchain, who is transacting with whom is not known i.e. transactors are anonymous. There is transaction anonymity and there is anonymity at user level as well. In case of traditional databases the users can easily be known and transactions can also be easily known until it is encrypted.
