The computer that solves the puzzle publishes its solution to the rest of the network and collects its reward: new bitcoins.
解開了謎題的計算機便把結(jié)果發(fā)布到互聯(lián)網(wǎng)上，并獲得新的比特幣作為獎勵。
And in the act of solving this puzzle,
在解開謎題的過程中，
these computers are actually helping to secure the Bitcoin blockchain and add to the list of transactions.
這些計算機也在逐漸加強比特幣區(qū)塊鏈的安全性，并把它添加入交易列表中。
There are actually people all over the world running this software, and we call them Bitcoin miners.
而在全球范圍內(nèi)，確實有人運行這樣的程序，他們被稱之為比特幣礦工。
Anyone can become a Bitcoin miner.
每個人都能成為比特幣礦工。
You can go download the software right now and run it in your computer and try to collect some bitcoins.
你現(xiàn)在就可以從網(wǎng)上下載這個程序，你現(xiàn)在就可以從網(wǎng)上下載這個程序。
I can't say that I would recommend it, because right now, the puzzle is so hard and the network is so powerful,
但我并不建議大家這樣做，因為現(xiàn)在隨著謎題越來越難，而互聯(lián)網(wǎng)又是如此的強大，
that if I tried to mine Bitcoin on my laptop, I probably wouldn't see any for about two million years.
我曾經(jīng)試過用我自己的電腦挖取比特幣，但我想我要在兩百萬年后才能挖到一個比特幣。
The miners, professional miners, use this special hardware that's designed to solve the puzzle really fast.
特殊的硬件被設(shè)計出來，以滿足專業(yè)的“礦工”需求，因為它們可以提供非常快的計算能力。
Now, the Bitcoin network and all of this special hardware,
據(jù)估計，現(xiàn)如今比特幣網(wǎng)絡(luò)以及所有的專用硬件所消耗的總能源，
there are estimates that the amount of energy it uses is equivalent to that of a small country.
接近于一個小國家所使用的能源。
So, the first set of cryptocurrencies are a little bit slow and a little bit cumbersome.
第一代加密貨幣的運行速度比較慢，效率也比較低。
But the next generation is going to be so much better and so much faster.
但它也在漸漸變得更快更好。
Cryptocurrencies are the first step to a world with a global programmable money.
要想進(jìn)入一個全球性程序化貨幣的世界，加密貨幣是需要邁出的第一步。
And in a world with programmable money, I can pay anyone else securely without having to sign up or ask permission,
在程序化貨幣的世界里，我可以放心的把錢支付給任何人，而不用我的簽名或是得到相關(guān)機構(gòu)的許可。
or do a conversion or worry about my money getting stuck.
也不需要兌換貨幣或者擔(dān)憂上當(dāng)受騙。
And I can send money around the world. This is a really amazing thing.
我的錢在全世界范圍都可以使用。這是件多棒的事呢！
