什么是比特币？这篇文章让你明白他的前世今生

比特币是一种数字货币，始于2009年。相比于传统的金融体系，比特币的特点是去中心化、匿名、透明、不可篡改，具有诸多优势。本篇文章将从比特币的定义、历史、特点、优劣势以及未来等几个方面来介绍比特币的全貌。

Bitcoin is a digital currency that began in 2009. Compared to the traditional financial system, bitcoin is characterized by decentralisation, anonymity, transparency, and immutable advantages.

一、定义

I. DEFINITIONS

比特币又叫数字货币、虚拟货币，是基于点对点网络协议而产生的一种去中心化、数字化的货币。它使用加密技术保证交易的安全性和匿名性，同时保证交易透明、无中介费用，可以全天候进行交易。比特币的供应总量上限为2100万，采用分布式账本技术，保证了比特币的去中心化、安全性和共识性。

Bitcoin, also known as digital currency, is a decentralized, digitized currency based on a point-to-point network protocol. It uses encryption technology to guarantee the security and anonymity of transactions, while ensuring that transactions are transparent and free of intermediary costs, and that transactions can be carried out 24 hours a day.

二、历史

II. HISTORY

比特币最早由中本聪 (Satoshi Nakamoto) 在2008年发布白皮书提出，2009年开始实际上线交易。当时比特币仅能用于一些地下黑市的交易，但在随后的几年内迅速发展。

Bitcoin was first proposed by Satoshi Nakamoto in a white paper published in 2008 and began a de facto line deal in 2009. At that time, Bitcoin could only be used for some underground black market transactions, but it developed rapidly over the next few years.

2013年，比特币曾经一度创下过每个比特币不到200美元的价格历史最高记录，并迅速火爆整个金融投资市场。但不久后，比特币价格又跌破100美元，导致投资者惊恐失色。

In 2013, Bitcoin once set an all-time record of prices of less than $200 per bitcoin, and quickly set fire to the entire financial investment market. But shortly thereafter, bitcoin prices fell by $100, causing investors to freak out.

之后，比特币市场逐渐回暖，在2017年底再次拉升至超过2.2万美元的历史高位，随后又一度暴跌，但目前比特币已经稳定在每个比特币6000-7000美元的价格区间内。

After that, the Bitcoin market was gradually warming, again rising to a historic high of over $22,000 at the end of 2017, followed by a sharp fall, but it is now stable within the range of $6,000 to $7,000 per bitcoin.

三、特点

III. Features

去中心化：比特币是通过点对点网络来实现的，没有中央机构进行管理，从而避免了中心化产生的单点故障风险。

Decentralization: Bitcoin is achieved through a point-to-point network with no central agency to manage, thereby avoiding a single point failure risk from centralization.

匿名：比特币交易使用公钥和私钥的方式进行，可以保证交易的匿名性和安全性。

Anonymous: Bitcoin transactions are conducted in the form of public and private keys that guarantee the anonymity and security of the transaction.

透明：比特币采用分布式账本技术，所有的交易和账户余额都可以被公开查看。

Transparency: Bitcoin uses distributed booking techniques and all transactions and account balances are publicly accessible.

不可篡改：比特币使用数字签名技术保证交易的真实性和不可篡改性。

It cannot be tampered with: Bitcoin uses digital signature technology to guarantee the authenticity and non-frozenness of the transaction.

无中介费用：比特币交易不需要中介机构，因此交易双方不需要支付中介费用。
