Cryptocurrency is a form of digital currency that operates independently of central banks, using blockchain technology to secure transactions and maintain a public ledger.
What is Cryptocurrency?
How Does Cryptocurrency Work?
- Blockchain Technology: At the core of cryptocurrency is blockchain, a public ledger that records all transactions across a network of computers. Each transaction is grouped into a “block,” and once a block is filled, it is added to the chain in a linear, chronological order. This structure ensures transparency and security, as altering any information in a block would require changing all subsequent blocks, which is nearly impossible. 2
- Transactions: When a user wants to send cryptocurrency to another user, the transaction is broadcast to the network. Miners or validators then verify the transaction using cryptographic techniques. Once verified, the transaction is added to the blockchain, making it permanent and publicly accessible. 2
- Mining and Consensus Mechanisms: New units of cryptocurrency are created through a process called mining, which involves solving complex mathematical problems. This process not only generates new coins but also secures the network. Different cryptocurrencies may use various consensus mechanisms, such as Proof of Work (PoW) or Proof of Stake (PoS), to validate transactions and maintain the integrity of the blockchain. 2
