A decentralized scheme (which the blockchain is based on) transfers authority and trust to a decentralized network and enables its nodes to continuously and sequentially record their transactions on a public “block,” creating a unique “chain”—the blockchain.

Of course, the blockchain is destined to affect almost everything. But the challenge is in knowing how, when, and what the impact will be. The first chapter was essential for laying out the multiple capabilities of the blockchain technology, paving the way for your understanding of its usage, and making you believe that peer-to-peer transactions can be finalized on the blockchain, without known intermediaries, except for the blockchain itself.
