What is Blockchain?

Blockchain is a technology in which all data is encrypted into blocks and joined together to form long chains.

Moreover, the information of the blockchain is not only located on a single server, but it will be automatically distributed and backed up on many different servers connected to the blockchain system, from which everyone has access. You can see and check your transactions. Each block contains information about the creation time and is linked to the previous block, along with a timecode and transaction data. Once the data is accepted by the network, there is no way to change it. Blockchain is designed to resist fraud and alteration of data.
