Bitcoin operates as a peer to peer network.

比特幣以點對點網路運行。

This means that everyone who uses Bitcoin is a tiny fraction of the bank of Bitcoin.

這代表每個使用比特幣的人都是比特幣銀行的一小部分。

But where do Bitcoins come from?

但比特幣來自什麼地方？

With paper money a government decides when to print and distribute money.

政府使用紙幣來決定何時印製和分配貨幣。

Bitcoin doesn't have a central government.

但比特幣沒有中央政府。

With Bitcoin, miners use special software to solve math problems.

至於比特幣，礦工利用特別的軟體來解決數學問題。

And are issued a certain number a bitcoins in exchange.

作為交換會發行一定數量的比特幣。

This provides a smart way to issue the currency.

這提供一種發行貨幣的聰明方法。

And also creates an incentive for more people to mine.

而且也吸引更多人來挖擴。

Since miners are required to approve Bitcoin transactions more miners means a more secure network.

由於礦工需要批准比特幣的交易，因此更多礦工代表更安全的網路。

The Bitcoin network automatically changes the difficulty of the math problems depending on how fast they are being solved.

比特幣網路根據數學問題的解決速度來自動改變難度。

In the early days, Bitcoin miners solved these math problems with the processors and their computers.

在早期，比特幣礦工用處理器和他們的電腦解決這些數學問題。

Soon miners discovered that graphics cards used for gaming were much better suited to this kind of working.

不久後，礦工發現遊戲顯示卡更適合用來完成這樣的工作。

Graphics cards are faster, they use more electricity and generate a lot of heat.

顯示卡速度更快，但它們需要更多電力而且會產生大量熱能。

The first commercial Bitcoin mining products included chips that were reprogrammed for mining Bitcoin.

比特幣挖礦的第一批商業產品，包括專門用來挖比特幣而重新編碼的晶片。

These chips were faster but still power-hungry.

這些晶片速度更快，但仍然很耗電。

ASIC, or application specific integrated circuit, chips are designed specifically for Bitcoin mining.

ASIC (特殊應用積體電路)，專為比特幣挖礦而設計。

ASIC technology has made Bitcoin mining even faster while using less power.

ASIC 的技術使比特幣挖礦速度更快，但是耗電更低。

As the popularity of Bitcoin increases, more miners join the network making it more difficult for individuals to solve the math problems.

隨著比特幣的普及，越來越多礦工加入這行列，使得單槍匹馬的礦工更難解決數學問題。

To overcome this, miners have developed a way to work together in pools.

為了解決這問題，礦工想出合力挖礦的方法。

Pools of miners find solutions faster than their individual members

礦工共同合作比起個人更能快速找到解決辦法，

and each miner is rewarded proportionate to the amount of work he or she provides.

而且每個礦工的報酬與他或她所提供的工作量成比例。

Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure.

挖礦是比特幣重要且不可或缺的一部分，可確保公平性，同時維持比特幣網路的穩定、安全及可靠性。
