A blockchain is a ongoing growing list of records, called blocks, which are linked and secured using cryptography. Each block contains a cryptographic hash of the previous block,a timestamp and transaction data. If we talk about design then, in blockchain, the modification of the data is not allowed.
Features Blockchain Application
Increased Capacity. One of the remarkable things about peer-to-peer technology is that they can increase the capacity of an entire network.
Better Security. Blockchains tend to have better security because there is no single point of failure to shut down the network.
