Introduction to Cryptocurrency

Cryptocurrency is a type of digital currency that uses cryptographic techniques to secure transactions and control the issuance of new units. Here are some basic details about cryptocurrency:

1. Decentralisation: Transactions in cryptocurrency do not require intervention from third-party institutions, enabling a trustless trading environment through blockchain technology.

2. Blockchain Technology: Cryptocurrency employs blockchain technology to record transactions, ensuring their security and immutability.

3. Consensus Algorithms: Cryptocurrency employs consensus algorithms to ensure the security and consistency of the blockchain. Common consensus algorithms include Proof of Work (PoW) and Proof of Stake (PoS).

4. Token: A token in cryptocurrency is a state variable defined within the blockchain, which can be transferred between different addresses on the blockchain.

5. Smart Contracts: Smart contracts in cryptocurrency are self-executing programs that can implement complex trading logic.

6. Public Chains, Consortium Chains, and Private Chains: Cryptocurrency can leverage public chains, consortium chains, or private chains to achieve various application scenarios.

7. Cryptocurrency Terminology: Understanding the fundamental terminology of cryptocurrency, such as HODL, moon, and altcoin, can help you better grasp the world of cryptocurrency.

This information provides a basic concept and technical foundation of cryptocurrency, helping you understand how cryptocurrency works and its applications.
