That's the core concept behind a proof scheme, and it is crucial for the functioning of a cryptocurrency - without a proof scheme requiring a scarce resource of some sort, the network cannot protect itself and would be easy to tamper with, making it useless as a currency. It makes it costly in the real world to participate in the network. The underlying trick here is to make a 'vote' require the usage of something scarce, something relatively expensive, something that you can't just infinitely wish into existence, like you could do with digital identities. After all, computations can be automatically and independently checked, and so nobody can pretend to have more computing power than they really do. The idea is that there is a finite amount of computing power in the world, computing power is expensive, and so you can prevent someone from tampering with the 'vote' by requiring them to do some difficult computations.

For example, how do you prevent one person from convincing the software that they are actually a million different people, and misusing that to influence that consensus process? If you have a majority vote system, then you want to make really sure that everybody can only cast one vote, otherwise it would be really easy to tamper with the outcome.Ĭryptocurrencies try to solve this using a 'proof scheme', and Bitcoin specifically uses what's called "proof of work". The idea of a currency that can be entirely controlled by independent software sounds really cool, but there are some problems. In practice, it's unfortunately not that simple, and cryptocurrencies end up being heavily centralized, as we'll get to later. On paper, this means that "nobody controls it", because everybody has to play by the predefined rules of the system. You can think of it kind of like an automated voting process.īasically, a cryptocurrency is a currency that is built as software, and that software runs on many people's computers. The rules are defined upfront and difficult for anybody to change afterwards, because some amount of 'consensus' (agreement) between the systems of different users is needed for that.

Instead, it's a system that's built out of technical rules, code that can independently decide whether someone holds a certain amount of currency and whether a given transaction is valid. Let's look at what cryptocurrency really is, the fundamental concept, in simple terms.Ī cryptocurrency, put simply, is a currency that is not controlled by an appointed organization like a central bank. That's not because you're not smart enough that's because such articles are intentionally written to be confusing and complex, to create the impression of cryptocurrency being some revolutionary technology that you must invest in, while trying to obscure that it's all just smoke and mirrors and there's really not much to it. They usually heavily use jargon and vague terms, make vague promises, and generally give you a sense that there must be something there, but you always come away from them more confused than you were before. There are plenty of intricate and complex articles trying to convince you that cryptocurrencies are the future. They're wrong, and are quite possibly trying to scam you. Whenever the topic of Bitcoin's energy usage comes up, there's always a flood of hastily-constructed comments by people claiming that their favourite cryptocurrency isn't like Bitcoin, that their favourite cryptocurrency is energy-efficient and scalable and whatnot.
