Absolutely not! Blockchain has many attractive features that make it a revolutionary technology. It has the potential to change many industries for good.Let\u2019s look at the digital record-keeping mechanism. For example, the online list of properties available for rent within a state. As and when a new property is enlisted, someone needs to add that entry to the database for the users to see. This person adds the property and updates the other necessary details about its ownership like price, possession type, etc.Now, consider the same scenario in the context of blockchain technology. Blockchain is a decentralized network. There is no central authority who updates the database with changes or adds new data. Rather, there are hundreds of thousands of blockchain validators or block miners who validate and authorize the transactions, mine new blocks.Each of these actions of each of the participants impacts the distributed ledger of the blockchain. In absence of a central authority approving each of these changes before they are reflected on the ledger, we need to have a set of rules.

There are several consensus mechanism algorithms. In this article, we will\u2026<\/p>","protected":false},"excerpt":{"rendered":"
