Cryptocurrencies are digital assets designed to function as a medium of exchange, store of value, or a way to access decentralized applications and services. Unlike traditional money issued by governments, cryptocurrencies operate on decentralized computer networks called blockchains.
A blockchain is a shared digital ledger that records transactions in a secure, transparent, and permanent way. Transactions are grouped into “blocks” and verified using cryptographic techniques before being added to the chain. Because of this process, no single party controls the network, and participants can agree on the validity of transactions without relying on a central authority such as a bank.
What is Crypto?
Cryptocurrencies operate through decentralization, meaning they are maintained by a global network of computers rather than controlled by a single organization. Their supply and issuance are typically governed by rules built into the software, which determine how new units are created and the maximum number that can ever exist; for example, Bitcoin has a fixed supply of 21 million coins.
Transactions take place directly between participants on the network and are verified by miners or validators, who contribute computing power or stake their own tokens to help secure the system. Beyond serving as a form of payment, cryptocurrencies can also provide broader utility, such as powering decentralized finance (DeFi) platforms, enabling digital collectibles (NFTs), or supporting smart contracts that automatically execute when predefined conditions are met.
How it works
Cryptocurrencies are digital assets that use blockchain technology to record transactions on decentralized networks. They are not issued or guaranteed by any government or central authority. Cryptocurrencies may be used for various purposes, including peer-to-peer payments, access to blockchain-based applications, or as a means of transferring value.
Because cryptocurrencies operate outside of traditional financial systems, they can be subject to significant price volatility, operational risks, and evolving regulatory frameworks. Investors should also be aware that cryptocurrencies are generally not backed by tangible assets and may lack the investor protections available in more traditional financial products.
