A cryptocurrency, such as Bitcoin, is a digital asset that serves as a medium of exchange in a peer-to-peer economic system. It utilizes encryption technology to verify and protect transactions while controlling the creation of additional units. Unlike centralized banking systems, the majority of cryptocurrencies achieve decentralization through a distributed network of computers called nodes that are spread across the globe. This means that as long as you have an internet connection, even a weak wireless signal, you can exchange valuable items worldwide with just a click of a button. Cryptocurrency transactions have lower costs compared to international bank transfers and are irrevocable, unlike chargeback transactions allowed by credit card companies. The issuance and management of cryptocurrency units are determined by network architecture, which is based on programming algorithms and cryptographic proofs. This set of predefined rules, or protocols, defines how the cryptocurrency system operates. Being decentralized means that cryptocurrency cannot be controlled by a single entity, allowing users to directly transact with each other without relying on intermediaries. However, it’s important to note that many cryptocurrencies are managed and developed by private companies and foundations, resulting in varying degrees of decentralization. With different network structures and node distributions, some cryptocurrencies are considered more centralized than others. The core component of most cryptocurrencies is a technology called blockchain. It is comprised of a linear chain where multiple blocks are securely encrypted. Each block contains a list of recent transactions and references to the preceding block, among other information. The blockchain’s primary function is to store permanent records of all confirmed transactions, serving as a decentralized digital ledger. This ledger is distributed across all nodes in the network, ensuring high resistance to modifications. In 2009, an enigmatic developer named Satoshi Nakamoto created the first decentralized cryptocurrency, Bitcoin. Its main concept was to establish an independent and decentralized electronic payment system based on mathematical proofs and cryptography. Like most cryptocurrencies, Bitcoin has a limited supply, meaning that it will stop generating new Bitcoins once it reaches its maximum supply. Generally, the total supply is publicly defined information created at the inception of a cryptocurrency. Today, there are over a thousand different cryptocurrencies within the world of Bitcoin, also known as altcoins or alternative coins. Each cryptocurrency has unique attributes and use cases.
