Everything you needed to know about how cryptos work
With the almost daily news coverage of cryptocurrencies, things can get overwhelming if you don’t exactly understand how the world of digital currencies works. Which is why we’ve put together an easy-to-understand guide explaining the main terminologies that make cryptocurrencies work. From blockchains to crypto mining to P2P, here’s what you need to know about cryptocurrencies and how they work.
Blockchain –
It sounds complicated but at its core, a blockchain is nothing but a type of database. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems that are a part of the blockchain. The system records information in a way that makes it difficult or impossible to hack or cheat the system.
Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. Blockchain differs from other databases that record information because it doesn’t belong to anyone, it belongs to everyone who is part of the ledger.
The data entered into blockchains can be decentralized, distributed, or centralized--depending on its use case. Bitcoin, for example, consists of thousands of computers, but each computer or group of computers that hold its blockchain is in a different geographic location and they are all operated by separate individuals or groups of people. This is an example of a decentralised blockchain. Because of its decentralised nature, all Bitcoin transactions can be transparently viewed by anyone with access to the blockchain.
