The one question that has come to every person's mind that what exactly is blockchain or for what purposes it is going to be used. The blockchain is an undeniably genius invention of Satoshi Nakamoto. It was invented in 2008 to serve as the public transaction ledger of the cryptocurrency bitcoin. But since that time it has evolved into something greater.
The blockchain is a continuously growing list of records called blocks. It is a distributed ledger that can efficiently take records of transactions happening between two parties in a verifiable way.
Once recorded the data in any given block cannot be altered without altering the subsequent blocks which will result in the collision of the whole network. The blockchain is a very secure way for the recording of events, medical reports, and the other records management functions
