What Is Cryptocurrency?
Cryptocurrency is any currency in digital and virtual form that uses cryptography as a means of ensuring security in transactions between users. Cryptocurrency does not have centralized governing bodies, such as traditional currencies (also called fiat currencies), where the role of the manager is usually government authorities, cryptocurrencies operate in decentralized networks based on blockchain technology and all transactions are controlled by the community and recorded in a public registry.
I would attribute the following to the main characteristics of cryptocurrencies:
- Decentralization: cryptocurrencies are not controlled by any single body and all payments are stored in online databases.
- Security: each transaction exists exclusively in digital form and is protected by cryptography.
- Transparency: cryptocurrencies operate using public blockchains, where each user can view all transactions made.
- Global availability: everyone has access to cryptocurrency and its functionality anywhere in the world, regardless of the country where they are located.
How Does Cryptocurrency Work?
Cryptocurrency is based on blockchain technology, a distributed ledger that records all transactions on a network of computers, that is, when a user makes a transaction in digital currency, a block is created based on the blockchain with a unique identifier and a set of data such as the amount, wallet data of the sender and recipient and is recorded in the general network and other participants confirm this transaction, below I will write in detail each point:
- Creating a transaction: When you send cryptocurrency, a transaction is created and broadcast to the network. It includes data such as the sender, the recipient, and the amount of cryptocurrency transferred. Each transaction is encrypted for security.
- Verification: Miners or validators confirm the validity of the transaction using consensus mechanisms such as Proof of Work (PoW) or Proof of Stake (PoS). This involves solving complex cryptographic puzzles or proving ownership of a certain amount of cryptocurrency, depending on the mechanism.
- Recording: Once verified, the transaction is grouped with other transactions into a block. This block is then added to the blockchain, which serves as an immutable ledger of all past transactions.
- Immutability: Transactions on a blockchain are permanent and cannot be changed. This ensures trust and transparency, as anyone can inspect the blockchain to verify the transaction history.
Additionally, blockchain networks operate without a central authority, relying instead on decentralized nodes that work together to maintain the system. This setup ensures that no single point of failure can disrupt the network, making it highly secure and resilient. Cryptocurrencies also use public and private keys to facilitate transactions. The public key acts as an address for receiving funds, while the private key is used to sign transactions, ensuring that they are legitimate and authorized by the owner. With these two techniques, cryptocurrencies allow transactions between users without the need for intermediaries in the form of centralized authorities such as banks. Cryptocurrencies are a fast and cheap way to manage your personal finances, no matter where you are in the world.
