比特币是什么?

作为加密货币的投资者, I have extensive knowledge of the various types of cryptocurrency, 以及每一个设计的目的, 作为一个会计专业人士, I keep up on the tax implications of 比特币 and Cryptocurrency. 然而, even with the gain in popularity with-in the last year, “比特币”的概念对大多数人来说都是陌生的, 包括美国国税局! 他们已经投入了学习资源, 调节, and gain an understanding of what  ‘Cryptocurrency’ should be classified as, 具有资本收益的资本资产, 像股票一样, 或资产,按个人税率征税. All they know is with potential for large gains, comes their chance to get big tax dollars! 阅读我们最新的比特币税 新闻.  But, let’s take a step back for a moment to answer the question: 比特币是什么?  To answer this, let’s explore this illustrative example posted at Coincentral.com.

比特币是什么?

2009年作为开源软件发布, 比特币 is often credited as the world’s first cryptocurrency and is best defined as a digital currency that only exists electronically.

比特币是分散的, meaning it doesn’t have a central issuing authority or political institution that controls the amount of bitcoin in circulation. 但比特币平台远非无政府状态.

The whole process is pretty simple and organized: 比特币 holders are able to transfer bitcoins via a peer-to-peer network. These transfers are tracked on the “blockchain,” commonly referred to as a 巨大的分类帐. This ledger records every bitcoin transaction ever made. Each “block” in the blockchain is built up of a data structure based on 加密Merkle树. This is particularly useful for detecting fraud or corrupted files. If a single file in a chain is corrupt or fraudulent, the blockchain prevents it from damaging the rest of the ledger.

Instead of relying on a government to print new currency, 比特币’s blockchain programming handles when bitcoins are made and how many are produced. It also keeps track of where bitcoins are and ensures the transactions are accurate.

目前有关于 1700万年 比特币流通. There isn’t a central regulatory agency or government controlling the supply of bitcoins, 这意味着供应是由设计控制的. The total supply to ever be created is capped at 21 million bitcoins.

This cap raises an argument that 比特币 could have problems scaling. 然而, since 比特币 is essentially infinitesimally divisible (meaning users can transfer as little as 0.00000001 bitcoins), this doesn’t really create a scaling issue. 2100万这个神奇的数字是任意的.

It’s believed that 比特币 was designed to become a deflationary currency to combat the government’s use of inflation as a hidden taxation to redistribute earned wealth. Many people praise 比特币 for empowering the people by overthrowing the currency printing powers of transient politicians.

比特币如何运作?

One of 比特币’s most appealing features is its ruthless verification process, 是什么将欺诈的风险降到最低. 因为比特币是去中心化的, volunteers—referred to as “miners”—constantly verify and update the blockchain. 一旦验证了特定数量的交易, another block is added to the blockchain and business continues per usual.

什么是“挖掘”?

Instead of a single central server verifying every transaction, essentially every other person on the network verifies each transaction.

提示“矿工.”

Let me simplify the process so we all understand: Miners are presented with a complicated math problem and the first one to solve the math problem adds the verified block of transactions to the ledger. 计算是基于工作证明(POW), or the proof that a minimum amount of energy was spent to get a correct answer.

There aren’t actual human beings hunched over computers with scraps of notebook paper and calculators doing pre-calculus homework; hardware is used to perform 比特币 mining.

比特币’s built-in reward system compensates successful miners with a chunk of bitcoins. The reward changes over time per 比特币’s programming, 区块奖励大约每四年减半一次. The current reward for each new block of verified transactions is about 12.5比特币.

The mining processes have become increasingly sophisticated. The most popular method uses ASICS–Application-Specific Integrated Circuits. ASICS are hardware systems similar to CPU computers that are built for the sole reason of mining bitcoins.

比特币 mining operations take a lot of effort and power, and the sheer amount of competition makes it difficult for newcomers to enter the race and profit. A new miner would not only need to have adequate computing power and the knowledge to use it to outcompete the competition, but would also need the extensive amount of capital necessary to fund the operations.
