Blockchain technology is described as a distributed ledger that is immutable which ensures secure transactions and decentralization as well as information, which makes transactions in digital currencies more easily accessible and secure. Blockchain is referred to as immutable since the alteration of data becomes more difficult while there's also no interference by a third party.
After the transaction has been completed after the transaction is completed, personal information remains private. However, the computers that process the transaction will record the transaction's details. Thus, based on the documented history of transactions that have occurred that the information cannot be altered in any way. In order to implement any modifications in one system, the entire systems would have to be altered and that is nearly impossible.
Blockchain technology first came into existence in 2009, when Santoshi Nakamoto introduced the Bitcoin Blockchain. This is the reason why blockchain technology is frequently associated with Bitcoin and, since then has been a major element of the digital landscape.
