What Is Blockchain?

Blockchain is like a massive list where everyone can see the same information. It lets people send money and information without using banks or third parties. It is like a chain because each piece of data links to one another, so it is simple to follow the chain back. Blockchain has many possible uses across various industries.

How Blockchain Works?

Blockchain app development works by having computers run the same software, making nodes. When you send information to another person over the blockchain, it sends it to every node in the blockchain network. The nodes check and ensure that the data is not tampered with before verifying and adding it to the list. This list is then updated across all the nodes and stored in a ledger. It ensures the authenticity of data sent over the blockchain.
