The blockchain is basically a distributed database. Think of a giant, global spreadsheet that runs on millions and millions of computers. It’s distributed. It’s open source, so anyone can change the underlying code, and they can see what’s going on. It’s truly peer to peer; it doesn’t require powerful intermediaries to authenticate or to settle transactions.
It uses state-of-the-art cryptography, so if we have a global, distributed database that can record the fact that we’ve done this transaction, what else could it record? Well, it could record any structured information, not just who paid whom but also who married whom or who owns what land or what light bought power from what power source. In the case of the Internet of Things, we’re going to need a blockchain-settlement system underneath. Banks won’t be able to settle trillions of real-time transactions between things.
So this is an extraordinary thing. An immutable, unhackable distributed database of digital assets. This is a platform for truth and it’s a platform for trust. The implications are staggering, not just for the financial-services industry but also right across virtually every aspect of society.
Most blockchains—and Bitcoin is the biggest—are what you call permission-less systems. We can do transactions and satisfy each other’s economic needs without knowing who the other party is and independent from central authorities. These blockchains all have a digital currency of some kind associated with them, which is why everybody talks about Bitcoin in the same breath as the blockchain, because the Bitcoin blockchain is the biggest.
The blockchain, the underlying technology, is the biggest innovation in computer science—the idea of a distributed database where trust is established through mass collaboration and clever code rather than through a powerful institution that does the authentication and the settlement.
