Tutorial Highlights

Blockchain technology is a structure that stores transactional records, also known as the block, of the public in several databases, known as the “chain,” in a network connected through peer-to-peer nodes. This storage is referred to as a ‘digital ledger.’ Every transaction in this ledger is authorized by the digital signature of the owner, which authenticates the transaction and safeguards it from tampering. Hence, the information the digital ledger contains is highly secure. In our blockchain tutorial, you’ll learn about bitcoin mining, how does blockchain work, the process of transaction, and more. You will also learn about the Blockchain Wallet, Cryptocurrency, and Ethereum. So start learning now to know the trending applications of blockchain, what is a smart contract, and how you can become a blockchain expert.
