Cryptocurrency Introduction

What is Cryptocurrency?

Cryptocurrency is a digital payment system that does not rely on banks to verify transactions. It is a peer-to-peer system that allows anyone, anywhere to send and receive payments. Cryptocurrency payments are not physical currencies carried and exchanged in the real world, but purely exist as digital entries in an online database describing specific transactions.

Characteristics of Cryptocurrency

1. Decentralized: Cryptocurrency has no central issuing or regulatory authority but uses a decentralized system to record transactions and issue new units.
2. Cryptography: Cryptocurrency uses encryption to verify transactions, providing security.
3. Digital Wallet: Cryptocurrency is stored in digital wallets.
4. Blockchain: Cryptocurrency operates on a distributed public ledger called a blockchain, which is a record of all transactions that currency holders update and hold.

Types of Cryptocurrencies

1. Coin: Cryptocurrencies built on independent blockchain networks, such as Bitcoin, Ether, and Tezos.
2. Token: Cryptocurrency tokens created on existing blockchain networks, such as ERC-20 tokens on Ethereum.
3. Non-Fungible Token (NFT): A special type of token representing unique digital assets.
4. Stablecoin: A token designed to maintain a stable price, often backed by reserves.：加密货币的概念和发展涉及多个人的贡献，而不是由一个人创立。以下是几个关键人物和事件：

   moto（中本聪）: He is the founder of Bitcoin, and on October 31, 2008, he published "Bitcoin: A Peer-to-Peer Electronic Cash System", first introducing the concept of Bitcoin and mining the first block of Bitcoin in early 2009 (known as the "Genesis Block").

Therefore, the development of cryptocurrency is a gradual process involving contributions from multiple individuals, rather than being solely established by one person.

   1. Encryption: Cryptocurrency uses encryption technology to protect transactions and user data. It enables users to control their funds without the need for trusted intermediaries.

   2. Transaction Process: Cryptocurrency transactions utilize decentralized blockchain, allowing users to create fast, secure, and transparent transactions at low costs. Transactions require verification through a two-factor authentication process.

   3. Miners and Nodes: Units of cryptocurrency are created through a process called mining, where miners use computer power to solve complex mathematical problems that generate coins. Cryptocurrency nodes maintain the latest records in the blockchain network and continuously validate and approve new transactions.

   4. Wallets and Transactions: Cryptocurrency is stored in digital wallets. Users can buy, sell, or hold cryptocurrency through brokers or exchanges and use wallets to store and spend them.

   In conclusion, cryptocurrency achieves secure, transparent, and fast transactions through blockchain technology, encryption security, and decentralized systems.
