Summary

This chapter introduced us to blockchain. First, ideas about distributed networks, financial transactions, and P2P networks were discussed. Then, we discussed the history of blockchain and various other topics, such as the elements of blockchain, the types of blockchains, and consensus.

In the coming chapters, we will be discussing blockchain in more detail; we will discuss the mechanics behind blockchain, Bitcoins. We will also learn about achieving consensus in much greater detail, along with diving deep into blockchain-based applications such as wallets, Ethereum, Hyperledger, all the way to creating your own cryptocurrency.
