A cryptocurrency is a digital currency that uses cryptography to secure transactions and operates on a decentralized network based on blockchain technology.
Unlike traditional currencies issued by central banks, cryptocurrencies are managed through distributed computer networks and do not rely on a central authority.
How do cryptocurrencies work?
Most cryptocurrencies use a blockchain, a public digital ledger that records all transactions conducted in the network.
When a user sends cryptocurrencies to another user, the transaction is verified by network participants and permanently added to the blockchain.
This system provides transparency and reduces the risk of fraud or manipulation.
