Come on, it consumes as much electricity as…(省省吧,哪有采金子耗电)
Bitcoin’s electricity consumption must be analyzed with respect to the future scenarios for the network. A lot of volatility is natural when market participants are trying to forecast whether bitcoin is (i) a speculative bubble that will implode and be worthless, (ii) a digital scarce asset that could replace gold as a store of value, or (iii) a monetary architecture that will serve as the core trust and verification layer for numerous types of transactions.
比特币到底要烧掉多少电取决于它以后怎么玩。一般大家觉得比特币未来可能有三种截然不同的结局(i)泡沫破裂,比特币归零,(ii)数字黄金,主要用于价值存储,或(iii) 一种货币体系,用来交易。(个人倾向于认为是2和3的结合)
If you subscribe to the bubble narrative, you can rest safely knowing that the electricity consumption of Bitcoin will return to zero in the near future. Miners will not expend energy if their bitcoin rewards are rendered worthless. If that’s your view, the discussion is moot.
如果你觉得比特币是泡沫,那恭喜你,比特币未来归0,那就再也不耗电了。这种咱也懒得浪费口水了。
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~我是分隔线。
二更
What if bitcoin replaces gold as an asset class for portfolio diversification and store of value? Now, to all the gold bugs out there, this is not our prediction. Thousands of years of history as sound money means gold will likely remain attractive. We merely use this example to show that bitcoin’s scarcity would be sufficient and environmental price would be much lower. Also to be clear, this scenario is not why we are excited about Bitcoin, but it may be the easiest use case to understand.
如果比特币变数字黄金了,咋整?咱把金子和比特币拿出来比划比划。金本位也搞了几千年了,一时半会当然也不会玩完。但是咱想想比特币的稀缺性,想想它对环境的破坏程度,那真的是完爆黄金。插一句,比特币的爆点可不止这三瓜五枣的,挤兑完黄金,高潮咱后面说。
Current gold production is around 3,000 tons a year against an inventory of about 200,000 tons, which is all the gold that has been produced throughout history. Of that, less than half is used for jewelry. The so-called stock-to-flow ratio, which is a measure of scarcity where a higher number is better, is therefore currently around 56: at the current rate of production, it would take 56 years to double the inventory.
黄金这玩意现在年产3,000吨,库存量约20万吨,注意了,咱人类存在这么多年,攒下的黄金就都在这里头了。这里面不到一半做首饰了。按现在这个状况,56年后咱攒下的金子可以翻个倍。
What’s the comparable scarcity of bitcoin? The current block reward is 6.25 bitcoin, which translates to about 900 new bitcoins every day, or 328,500 per year. Given 18.6 million bitcoins in existence, the stock-to-flow is currently approximately 56, which is on par with gold. But after the next halving, which will happen during the spring of 2024, the stock will be higher and the flow will be lower, so stock-to-flow will be more than double that of gold: Bitcoin will be much scarcer than our scarcest commodity.
比特币现在每天产出来900个左右,每年328,500个,目前已经挖出来的有1860万比特币。要是产量一直这样,也差不多是56年翻一番,但是,但是,但是,中本聪这个鬼才已经下了套了,在比特币的程序设计中,每四年比特币的产量都会减半,最近的产量减半是2024年。换句话说,相比起黄金,比特币的稀缺性会逐渐完爆黄金,而且是指数型的那种。降维打击听过没?没错,在过个十年二十年的,地球上任何资产的稀缺性都将和比特币不在一个维度上!!!
The estimated CO2 emission for producing new gold is more than 100 million tons per year. Estimates vary, but recent studies put Bitcoin’s around 30 million tons annually. That’s less than one third of gold’s CO2 emissions. And as renewables increase in the mix, Bitcoin’s CO2 emission intensity should drop significantly. Note that this is still disregarding the cost of refining and storing gold, as well as the negative impact land excavation in less compliant regions of the world has on both people and the environment.
然后咱再来唠唠坏境成本的问题。目前黄金生产每年要排放大约1亿吨的二氧化碳。 而比特币大概为3000万吨, 不到黄金的三分之一。 最重要的是,比特币对能源不挑。就是供着一些电脑嘛,天时地利啥的咱都能凑合,太阳能风能都没差,所以比特币造出来的二氧化碳估计还能在降一降。另外黄金这玩意,挖出来了咱还得提炼,还得找个靠得住的地方存着,另外挖完了还得给矿区,给当地的环境擦屁股,这些事你想想多烧钱,得多排多少气。比特币就完全没有这些破事。
That leaves the most optimistic scenario for bitcoin. The one that gets us excited. Where Bitcoin’s ability to verify transactions between two parties without a trusted third party is used to build an ecosystem of applications.
唠了半天重于到说重点了,这管鸡血大家可都得接好了。比特币最牛逼的地方在于,任何两个人做买卖,不需要一个第三方的中介,咱就能把生意做下来,而且还不担心上当受骗。你品,你细品,这它喵的以后会在造一个金融系统,把现在的这些老古董给收编了啊!!!
We are already exploring Blockstream’s Liquid and Elements products for industrial applications: foreign exchange, cash management, trade settlements, emission verifications. But these are merely the obvious ones. The broader potential? Economic access for the unbanked through saving, spending, and lending services. Micropayments. Ownership of private data. Technology that can disrupt compliance, which is now more than ten percent of bank employees and increasing. With the added benefit of improved security and near-instant settlement.
Blockstream已经在玩一些传统的金融产业了,外汇,现金管理,贸易结算,发行验证。但是就这?那也太小看咱们的野心了。咱现在琢磨的是,要让那些开不了银行账户的人也能玩金融,要让大家伙都能对自己的私人数据有所有权,都能用微额付款的技术。偷偷的说,咱也在关注逃避监管的技术手段,别笑,超过10%的银行雇员都在偷偷用。还有就是用比特币做买卖,更安全,也更高效。(即时结算)
We obviously can’t know how this will play out. Many technologies will compete to solve these challenges. But we do know that many applications are too important to leave the verification to centralized systems owned by a corporation or controlled by a single country.
饼画的有点大,其实咱现在也不知道怎么弄,但是现在很多新的技术已经在尝试解决这些问题了,而且竞争还很激烈。但是毋庸置疑的一点是,这些技术太太太重要了,咱不能把这些技术给一个人,一个公司,或者一个国家给控制了,咱必须通过去中心化的方式发展这些技术。(很简单的一个例子,robinhood拔网线阻止散户们买gamestop的股票,所以咱需要去中心化交易所这样的技术)
So what about the electricity consumption in the scenario that we are most excited about? Clearly, the protocol is designed to cut the rewards in half every four years or so. Miners will only expend the electricity if it remains profitable. 18.6 million of the maximum 21 million bitcoin exists today. So at the end of this year, 90 percent of the bitcoin is already in existence and paid for. Nine tenths of the infrastructure is there.
Since the block reward goes down significantly over time, the miners would be willing to expend less electricity all things equal. Either the variable transaction fees or the price of bitcoin have to increase substantially to compensate the miners. Since the block reward will approach zero, fees are the only viable long-term compensation mechanism.
Since the transaction volume cannot increase given Bitcoin’s design, fee increases imply that the value of single transactions must be substantially higher than today. Presumably, that’s only possible if every transaction on the mainchain always involves very large amounts. Billions of smaller transactions would have to execute with acceptable security in second layers and sidechains.
Again, all of this is only commercially and economically viable if the value of verifying large transactions without a trusted third party is sufficiently high. This implies high demand for the network’s architecture, which again means that useful applications that create tremendous value have been built on top of the core network. Bitcoin can therefore only survive, and electricity will only be consumed, if the value created by the network is sufficient.
那这种终极进化的场景下,比特币有多烧电呢?来来来,咱从技术上好好唠唠。。。(以下省略500字,没知识背景的请自行谷歌。)总之吧,只要比特币能解决大买卖(亿级别的)的信任问题,踢掉中介,并且安全可靠,你想想这里面多大的价值,你还惦记着那点电费?出息。
Even completely disregarding Bitcoin acting as an economic battery that may improve the economics of renewable projects, which could accelerate the installation of intermittent sources of electricity, we don’t see a long-term problem related to Bitcoin’s electricity consumption.
另外比特币还能用清洁能源,还能用那些不好用的间歇性能源,并且把它们变成钱。哎呀,又唠回去了,这么一点点电,毛毛雨啦,咱能别唠了嘛。比特币这辈子都不会影响你造你那点电。
If it’s a bubble, it dies and consumes nothing. If it’s digital gold, it’s more efficient and will emit much less than the asset it disrupts. And if it’s really successful, it’s because of demand from truly value creating applications that define our future and should be worth the electricity.
唠了一圈,总结一下。比特币要是气泡,它就会归0,没人用也不会有耗电。 比特币要是数字黄金,那它比黄金效率更高,对环境更友好。比特币要是实现 终极进化,那咱这点电真是用对地方了。
Fine, but how will it scale? (比特币怎么把交易量做大?)
It is true that the Bitcoin mainchain cannot process the number of transactions that we depend on in modern society on its mainchain. But that’s because Satoshi Nakamoto’s design didn’t trade censorship resistance and security for scalability. So scalability has to be solved by making slight tradeoffs.
咱们现在这个社会的交易量有点大破天,比特币的交易吞吐量现在还有点吃不消。为了高度的去中心化和抗审查,比特币当初设计的时候牺牲了一些可扩展性。人在屋檐下不得不低头,为了比特币神教发展壮大(扩大交易吞吐量),有时候也得适当低头。
Bitcoin doesn’t compromise. To ensure it’s open and secure, resistant to censorship and retroactive edits, it’s decentralized. But that’s a major drawback for scalability: Keeping one central spreadsheet up to date is obviously more efficient than having numerous copies that all must be updated. A Bitcoin transaction takes about ten minutes to be confirmed and the design capacity is about seven transactions per second. Hardly sufficient to deal with today’s transaction volumes.
比特币的骨头还是很硬的。为了保证安全性和去中心化,以及链上的交易数据不被篡改,咱给每个矿工的电脑上都安装了一个完整的账本。谁造假了,咱拿出其它人的账本一对照,分分钟揪出这大尾巴狼。不过这个特点吧也有个大问题,就是每笔交易都相当于要发一个群邮件,每个人的账本都得更新一遍。所以交易量大了就可能宕机。目前每笔比特币交易大约需要10分钟的网络确认时间,整个比特币网络设计的处理能力是每秒处理7笔交易。跟需求比起来,感觉就是苍蝇喂老虎,肉也算是个肉,解决不了核心需求。
But when I heard Jack Maller’s talk about the Lightning layer I had another Rosselini moment. The Lightning Network is built on top of Bitcoin to make it scale. Transactions are done in bilateral channels that connect in a network and each channel is anchored to Bitcoin’s mainchain with a single transaction. Lightning transactions complete in milliseconds and can process millions per second with hardly any use of electricity. It therefore leverages Bitcoin’s security while increasing speed and reducing cost to levels not achievable by legacy payment rails.
不过也不是没有办法。Jack Maller给我吹的那个闪电网络,我觉得有戏。啥是闪电网络呢?就是两个固定的交易伙伴,在比特币的区块链上建一个封闭的通道做买卖,今天你买我5毛钱的红薯,明天我买你1块钱的土豆,你来我往的,咱自己记个账(不需要发送到比特币的区块链上,也就不需要更新每个账本),等年底了咱合计合计,最后跟比特币的账本结算一下。每天的这些零碎交易就是闪电交易,1秒钟就可以处理数百万次,还贼安全,还没有交易手续费。(译者注:译者注:老爷子说的唾沫横飞,但其实闪电网络的局限性和问题还是挺大的,应用场景目前很局限,安全性也有待考验。这几年进展不错,但能不能真正成为扩容的利器还需要时间来给出答案)
Does a global distributed network of bilateral payment channels sound impossible? In fact, that’s how spot foreign exchange works. Aker is the largest investor in Abelee, a non-bank liquidity provider in the foreign exchange market. We have spent a lot of time learning about the microstructure of financial markets. It’s only a matter of time before the old and the new world of money is seamlessly connected.
点对点的跨境支付网络听起来高大上不?嘿嘿嘿,老哥我的公司早就玩上了。我们Aker大手笔投的Abelee,就是干这事的(点对点外汇交易)。金融市场的那些旮沓角落我们都扫过了,不是我跟你吹,前浪迟早被后浪给拍死,咱玩的这些小众玩意迟早成为主流。
On that night, with all of us on video from Chicago, Tel Aviv, and Oslo, Mallers sent dollars from a regular bank account in the U.S. via a wallet in Tel Aviv and further on to Oslo. Then, for fun, we sent it to an Aker colleague in Accra, Ghana. All these transactions took place instantaneously and at nearly no cost. This creates the possibility of programmable microtransactions, a payment stream, which can unlock limitless opportunities.
别不信,就早几天晚上,我们就视频见证了怎么把美金在不同的国家中转圈圈,还又快又没有手续费。想想看,这要是变成主流了,这里面有多大的蛋糕可以啃?
Applications will have different needs and people will be willing to make slight tradeoffs to achieve those. I’m certain that, with time and creativity, applications that scale in sidechains and layers on top of Bitcoin will flourish. This ecosystem can provide massive scalability, and will only need to settle with the mainchain now and again. Like getting a stamp of approval from the source of absolute truth.
只要好处给够,咱们都是好说话的嘛。比特币这玩意,可能有这的那的缺点,但只要饼足够大,咱都可以忍受,可以等它慢慢进化。我是无脑看多的,给它点时间,侧链和层上扩展的技术会慢慢解决这些问题,做出改变世界的应用来。这些应用类似于闪电网络那样,给比特币生态带来足够的可扩展性。
As such, we believe Bitcoin will scale brilliantly in layers upon layers that make the trade offs applicable to particular application. And as we will see in the next paragraphs, it may provide the opportunity to build an entirely new architecture for how information flows in society.
总之,你也甭管我刚刚提到的闪电网络到底行不行,这不重要。你就记住一点,比特币它总会有办法来实现扩展的。下面咱来说说它具体的应用。
Still, doesn’t bitcoin enable undesired activities? (玩比特币的没几个好人?)
The first industry to take advantage of the internet’s potential was arguably the pornographic industry. When we founded Cognite, a company that enables siloed data and legacy systems to seamlessly interact to improve access and flow of industrial data, we did that with internet pioneer John Markus Lervik. He told us how his first company, Fast Search & Transfer—later acquired by Microsoft to power their search functionality—was constantly approached by the pornographic industry in the late nineties: they wanted access to the company’s leading and proprietary image compression algorithms.
