『壹』 币圈的PoS挖矿和PoW挖矿有什么区别

POW挖矿需要购买矿机，电脑越好，算力越高、挖矿时间越长，你获得的货币就越多。POS挖矿可以理解为持币的量和时间产生的收益，通俗来说就是放银行产生利息，区别于银行的是币还是掌握在自己手里，就像CellETF平台(celletf.io)的质押挖矿，把币放进去可以按日计算收益利息，非常省力方便。

『贰』 币圈是什么意思

所谓的币圈，即数字货币玩家天然形成的圈子。币圈不大，但是人数也不算少，而且在人群中基本上属于小众异类，但林林总总算是一个圈子，赚钱的人不多，形形色色的赚钱方式也都被迅速地拷贝过来，ico、炒币、挖矿等。

币圈赚钱的方式有很多，最主要的炒币、ICO众筹、搬砖等。币圈的法币是法定货币，是由国家和政府发行的，只有政府信用来做担保，如人民币、美元等等。

1、币圈token：

token，通常翻译成通证。Token是区块链中的重要概念之一，它更广为人知的名字是“代币”，但在专业的“链圈”人看来，它更准确的翻译是“通证”，代表的是区块链上的一种权益证明，而非货币。

Token的三个要素

一是数字权益证明，通证必须是以数字形式存在的权益凭证，代表一种权利、一种固有和内在的价值；

二是加密，通证的真实性、防篡改性、保护隐私等能力由密码学予以保障；

三是能够在一个网络中流动，从而随时随地可以验证。

2、币圈建仓：

币圈建仓也叫开仓，是指交易者新买入或新卖出一定数量的数字货币。

3、币圈梭哈：

币圈梭哈就是指把本金全部投入。

4、币圈空投：

空投是目前一种十分流行的加密货币营销方式。为了让潜在投资者和热衷加密货币的人获得代币相关信息，代币团队会经常性地进行空投。

5、币圈锁仓：

锁仓一般是指投资者在买卖合约后，当市场出现与自己操作相反的走势时，开立与原先持仓相反的新仓，又称对锁、锁单，甚至美其名曰蝴蝶双飞。

6、币圈糖果：

币圈糖果即各种数字货币刚发行处在ICO时免费发放给用户的数字币，是虚拟币项目发行方对项目本身的一种造势和宣传。

7、币圈破发：

破指的是跌破,发指的是数字货币的发行价格。币圈破发是指某种数字货币跌破了发行的价格。

8、币圈私募：

币圈私募是一种投资加密货币项目的方式，也是加密货币项目创始人为平台运作募集资金的最好方式。

9、币圈k线看法：

K线图（Candlestick Charts）又称蜡烛图、日本线、阴阳线、棒线、红黑线等，常用说法是“K线”。它是以每个分析周期的开盘价、最高价、最低价和收盘价绘制而成。

10、币圈搬砖：

搬砖就是，从币价低的交易所买入数字货币，然后转到价格高的交易所卖掉。

『叁』 我想加入矿圈，有什么好办法呢坐标帝都

相对于币圈，矿圈要更高端一些，不信可以问问身边的人知道挖矿的有多少。个人用户没有场地和电，没有专业知识，投入产出比太低了。深山老林、电力能源便宜的地方，咱们普通人又根本没这个资源。所以我建议还是多多学习吧，金色财经啊，巴比特，火星财经，包括科技类的文章都要多看看多学学。
另外参加一些商学院，加入正确的圈子和平台也很重要。平台的话，比如友矿，非常适合新手学习练手，门槛低些，他们的一些线下meetup也经常能够请到矿圈的资深人士，有什么不懂的多多向别人请教，相信通过这样系统化的学习，你早晚也会变成矿圈的资深达人！

『肆』 数字货币挖矿风云如何

“一币一别墅”的财富神话依然在币圈里广为流传，不断有新的投资者跃跃欲试。但其实，从矿机厂商到大矿场主，再到矿池，这个小圈子已经形成了一个稳定的权力结构。

制售矿机、挖矿、建矿场、搭矿池，“矿圈”成为区块链世界里另外一条发财之路，矿机也成为一门鲜为人知的“大生意”。

按照比特币发明者中本聪的设想，理想的状态应该是“去中心化”的，算力分散在全球各地。但是，与去中心化背道而驰，矿池是绝对的中心化，越来越多的矿机接入到矿池里。

本文首发于南方周末

“如果说炒币是一条不归路，那么投资矿机就是一笔稳赚不赔的生意，回收成本只是时间问题。”深圳爱播时代科技有限公司总经理钟熙算了一笔账，一台矿机每天200元收益，120天可以回本，之后就是利润了。

2017年10月，钟熙在主业之余，加入了挖矿大军，并迅速成为矿圈大佬，他在江西、四川、贵州等地运营着多个大矿场。

其实这个“稳赚不赔”的生意仍然依赖于币价的持续高涨。过去两个月时间，比特币币价从15000美元跌到了10000美元左右，甚至一度跌破6000美元，使得矿机回本周期延长，如果一直跌下去，盈利也就遥遥无期了。

在比特币问世4年之后，也就是2012年，可以量产的矿机才出现。在此之前，挖矿主要是私人行为，家用电脑就可完成。“那时，家用电脑就是印钞机，每天都能挖出不少比特币。”资深数字货币玩家、早年卖过矿机的黄世亮向南方周末记者回忆。

矿机出现后，挖矿开始“社会化”，出现了矿场和矿池，挖矿成为一件集体工作。单独的矿机被矿场托管，就像生产线上的工人，只要摆在那里，就可以每天领薪水。

制售矿机、挖矿、建矿场、搭矿池，“矿圈”成为区块链世界里另外一条发财之路，矿机也成为一门鲜为人知的“大生意”。

中国则成为全球最大的矿机生产地。从2012年开始，在中国诞生了一批矿机生产商，如生产烤猫矿机的深圳比特泉有限公司，还有现在赫赫有名的比特大陆、嘉楠耘智和亿邦通信。在深圳华强北，到处也都可以看到外国人带着翻译询问矿机价格。

近期，比特大陆CEO詹克团在接受媒体采访时称，这个成立仅4年的创业公司，2017年的营收规模约25亿美元。比特大陆号称全球最大的矿机生产商，他们的蚂蚁矿机一直都是币圈和矿工世界的硬通货。

与币圈一样，矿圈也需要信仰——要坚信矿机每天机械地数学运算能够创造巨大财富。

不过，与比特币所宣扬的“去中心化”背道而驰，矿工的世界正在走向“中心化”。矿机销售商自己建矿场，投资者买完矿机之后，又被销售商托管；而生产商则自己建矿池，又将矿场给管起来。

这种“中心化”的过程，使得矿圈的财富被少数人攫取，钟熙要想进入到核心圈子，也并不容易。

算力“中心化”

矿场的主要作用，是给分散的矿机提供一个运转的地方。但真正起到整合作用的则是“矿池”。

所谓“矿池”，可以简单理解为“合作挖矿”。矿工和矿场们，把算力交给矿池，由矿池作为唯一的地址，来接入数字货币网络进行挖矿，再按照矿机的算力，给矿工分发红利。

矿池的历史要比矿机更悠久。2010年11月，名为Slush的矿池出现，它的官网在今天还写着是“世界上首个矿池“，这个称号也被币圈所公认。与矿场相比，矿池的搭建需要一定的技术，门槛相对更高。

国内一家知名矿池的负责人向南方周末记者解释矿池的原理。他把挖矿比作买彩票，一个人挖，中奖的概率很不稳定，可能今天中了10万，以后半年都不中。

“把买彩票的人聚到一起，统一买，无论谁中，根据出钱比例来分成。在币圈，矿池就发挥这个作用。”该负责人说。

矿机连接矿池并不复杂，根据各大矿池的操作指南，一般只要几步就可完成，然后就根据自己提供的算力，从矿池获得收益。矿机就像一个站在生产线上的工人，每天领取固定的薪水。

掌握巨大算力和众多矿机的矿池，在币圈和矿圈都有着绝对的发言权。比如，如果要发行新的数字货币，或者要主导比特币分叉，一般要获得矿池的支持，没有矿池的支持，新币种没人挖，也就没有了意义。

此外，当一个抢手的新币面世时，矿池也可以利用自己所掌握的矿工，快速打包，在这些新币的抢购中占得先机。

2017年6月份，SNT和EOS两大代币发行时，南方周末记者就见证了矿池抢购代币的场景。由于投资者太多，很多个人投资者无法将资金打入到指定位置，但一家矿池的负责人，就可以轻而易举地完成这一操作。

按照比特币发明者中本聪的设想，理想的状态应该是“去中心化”的，算力分散在全球各地。但是，与去中心化背道而驰，矿池是绝对的中心化，越来越多的矿机接入到矿池里。

2018年1月18日，康奈尔大学计算机教授埃敏·允·西拉什等5人合著一篇论文，直指两大数字货币比特币和以太坊背后存在隐性的权力结构，挖矿过于集中，其中比特币50%的算力被四大矿池所控制。

其实，这个问题一直存在。4年前，以太坊创始人Vtalik在写以太坊白皮书时就注意到了这个问题，他写道：“这个问题可以说很严重，在本文写作时，最大的两个矿池，间接地控制了大约全网50%的算力。”

直到今天，这个问题也没能解决。一位以太坊白皮书的早期翻译者向南方周末记者无奈地表示：“这不是技术问题，而是人的问题。”

隐性的权力结构

在矿圈，食物链顶层就是矿机生产商。目前，公认的三大矿机生产商均位于中国。他们通过生产销售矿机，获得大量的利润，同时也涉足矿场和矿池的建设，布局在整个币圈的话语权。

蚂蚁矿池是全球排名前二的大矿池，它的算力占据全网算力的17%，但根据工商资料，该矿池是由比特大陆一手创办；嘉楠耘智的几位投资人，同时也是杭州矿池科技有限公司的投资人，后者有自己的矿池Hash和挖矿平台，不过矿池已于2017年底停止运营。

亿邦通信则在内蒙古呼和浩特市、乌海市，新疆准东经济开发区成立了三家区块链公司。亿邦通信的一位销售人员向南方周末记者介绍，他们在这三地都有矿场和挖矿业务，但这些矿场也已全负荷运转，没有机位可以托管新的矿机了。

“我们正在俄罗斯的伊尔库茨克搭建新矿场，那里电费低很多，新矿机可以在那里托管。”该人士说。

在矿机厂商之上，则是芯片巨头的收割。“矿机的核心技术在芯片上，谁有矿机芯片，谁就可以生产更多矿机。”丁杨对南方周末记者说，芯片主要掌握在几家巨头厂商手中，如台积电、英伟达、AMD等。

从2015年开始，台积电一直都是嘉楠耘智的最大芯片供应商。2015年，嘉楠耘智从台积电采购的芯片，占据嘉楠耘智所有采购量的69.62%，此后这个数据一直维持在60%左右。嘉楠耘智的大部分利润，均被台积电赚走。

2018年1月18日，在台积电第四季度财报的说明会上，董事长张忠谋就称，虽然今年的移动业务前景较弱，但公司的营收依然会增长10%—15%，关键因素之一就是持续稳健的加密货币开采对芯片的需求。

在矿机厂商之下，则隐藏着另外一种权力结构。嘉楠耘智2017年的招股书上，透露了这个秘密。2017年前4个月，嘉楠耘智的前五大客户中，有四大客户属于“个人”。而根据公开资料，其中有三人均是币圈鼎鼎大名的“腕儿”。

第一大客户吴钢是最早的一批矿工，后来创办了Haobtc，该公司拥有一个全球前十的矿池；第二大客户林志鹏是小强矿机的创始人，很早便从事矿机的生产销售，其与第六大客户谢维钦，一直是合作关系；第三大客户王晋创办了币圈资讯网站比特帮。

这些大客户均不是单纯的矿工，他们都在币圈拥有着自己的影响力。机械运转的矿机给他们带来收益的同时，也带来了话语权。

据比特大陆一位内部人士介绍，比特大陆的大客户中，也多为币圈的大佬。不过，比特大陆官方婉拒了南方周末记者的采访，该公司公关部回应称，由于与客户签署了保密协议，该方面内容不方便透露。

“一币一别墅”的财富神话依然在币圈里广为流传，不断有新的投资者跃跃欲试。但其实，从矿机厂商到大矿场主，再到矿池，这个小圈子已经形成了一个稳定的权力结构。

新入局者，大多只能做被收割的“韭菜”

『伍』 币圈中什么是矿工费，如何才能成为一名旷工

矿工费就是指在数字货币转帐时，付给矿工的激励费用，这个数额并不是固定的，当然你付的矿工费越多，被打包的速度越快，可以理解为区块链网络中的交易费用。有兴趣可以了解下CellETF

『陆』 在币圈也有一段时间了，准备试一下挖矿，现在进矿圈合适吗

不太合适，还是好好上班巴

『柒』 币圈的永续合约怎么理解

根据合约计价单位和缴纳保证金基准单位的关系，永续合约分为正向合约和反向合约。所谓反向合约也叫币本位合约，即以USD计价，以对应数字资产币种收取保证金和计算盈亏。正向合约，即以USDT计价，以USDT作为保证金和计算盈亏的合约。

因为具备这些特点，套利者使用永续合约执行策略时，不需要担心合约交割而价差还没有向预期方向变化而产生额外的换仓成本，可以长期持仓，不受交割期的影响，可以使你的交易更加灵活。套保者也可以使用永续合约可以方便地选择套保时间。

OTC交易注意事项

需要注意出入金要准备专卡专用，资金流动是会感染的，互相转账，只会导致卡全部被冻结，给个人图增烦恼，并且切勿使用工资卡，这样出金被冻结后，不仅影响到生活还会影响到工作。

使用银行卡去做出金准备前，应该先测试一下银行卡是否仍然可以正常使用，不要事后拍断大腿，小心使得万年船。

在交易所进行交易时，我们有的时候会发现盘一价格和其他价格比特别突出，这种情况的商家，一般都来路不正，虽然交易所有对商家的审核和平台风控尽责的义务，还是会被人抓住可乘之机，反洗钱是银行都解决不了的问题，我们也不能强加给交易所。

『捌』 币圈和链圈的区别是什么

链圈”、“币圈”、“矿圈”不少人傻傻分不清楚，但撇开那些关联，三者的本质其实还是大相径庭的。在区块链生态中，目前大致划分为三个圈，分别为“链圈”、“币圈”、“矿圈”。三者相互关联，却也大有区别，
链圈——链圈，技术派的代表。门槛相较于其他两个圈更高，主要专注于区块链技术的发展与应用，所以对于普通人来说，比较难跨进去。
区块链可以分为三阶段：私有链、公有链和联盟链。
币圈——币圈，可以说是最丰富多彩的一个圈。专注于炒加密数字货币，为三圈中入门门槛最低的圈。主要特点为发币和炒作，基于区块链技术发行的币为主流币，如比特币、以太坊等，风险较小。而ICO发行的币，则为山寨币，存在一定风险，炒作则是因为行业缺乏监管，后台操盘常见造成，目前我国已禁止ICO。
矿圈——矿圈，是专注于“挖矿”的一群人所在的圈子。这个挖矿不同于生活中的挖矿，而是为了获得虚拟货币奖励所进行的一种行为，参与挖矿的人，则被称之为矿工。
挖矿需要借助工具，早期通过一般电脑即可挖矿，之后随着挖矿人数的不断增加，开始发展成矿机挖矿，矿池挖矿。挖矿所需付出的成本较高，比如耗电巨大，电费也是一笔不小的支出。
矿圈的门槛略高于币圈，但低于链圈。大部分人都听过挖矿，但真正参与挖矿的人还是较少。
而相比链圈和币圈，矿圈还会受到外部自然环境的影响，如矿场矿机遭到损坏等。
现在的大背景下，炒作区块链的概念已经毫无意义了。区块链从业者一定是要想办法为这个社会贡献价值，去创造财富，而不是蒸发财富，所以我们不区别币圈、链圈，能创造价值的就是好圈。

『一』 What is the difference between PoS mining and PoW mining in the currency circle?

POW mining requires the purchase of a mining machine. The better the computer, the higher the computing power and the longer the mining time. The longer you get, the more currency you get. POS mining can be understood as the income generated by the amount and time of holding coins. In layman's terms, it means lending money to the bank to generate interest. What distinguishes it from banks is that the coins are still in their own hands, just like the pledge mining of the CellETF platform (celletf.io). Mine, put the coins in and the income and interest can be calculated on a daily basis, which is very labor-saving and convenient.

『二』What does currency circle mean?

The so-called currency circle is the naturally formed circle of digital currency players. The currency circle is not big, but the number of people is not small, and it is basically a niche among the crowd. However, it is still a circle. There are not many people who make money, and all kinds of money-making methods are quickly copied, such as ICO and speculation. coins, mining, etc.

There are many ways to make money in the currency circle, the most important ones are currency speculation, ICO crowdfunding, brick-and-mortar, etc. The legal currency in the currency circle is legal tender, which is issued by the country and the government and is only guaranteed by government credit, such as RMB, US dollars, etc.

1. Currency token:

Token, usually translated as pass. Token is one of the important concepts in the blockchain. It is more commonly known as "token", but in the eyes of professional "chain circle" people, its more accurate translation is "pass", which represents the area. A proof of stake on the blockchain, not a currency.

The three elements of Token

The first is the digital proof of rights and interests. The token must be a certificate of rights and interests in digital form, representing a right and a right. An inherent and intrinsic value;

The second is encryption. The authenticity, tamper resistance, privacy protection and other capabilities of the certificate are guaranteed by cryptography;

The third is the ability to be used in a It flows in the network and can be verified anytime and anywhere.

2. Opening a position in the currency circle:

Building a position in the currency circle is also called opening a position, which refers to a trader's new purchase or sale of a certain amount of digital currency.

3. Coin Stud:

Coin Stud means investing all the principal.

4. Airdrop in the currency circle:

Airdrop is currently a very popular cryptocurrency marketing method. In order to provide potential investors and people who are passionate about cryptocurrency with information about the token, the token team will conduct frequent airdrops.

5. Lock-up in the currency circle:

Lock-up generally means that after investors buy and sell contracts, when the market trend is opposite to their own operations, they open a position opposite to their original position. The new position is also called locking, locking, or even euphemistically called butterflies flying together.

6. Coin Circle Candy:

Coin Circle Candy is the digital currency that is released for free to users when various digital currencies are first issued during the ICO. It is the virtual currency project issuer’s contribution to the project. A kind of momentum building and publicity in itself.

7. The currency circle breaks:

Break refers to falling below, and hair refers to the issuance price of digital currency. A currency circle break means that a certain digital currency falls below the issuance price.

8. Coin Circle Private Equity:

Coin Circle Private Equity is a way to invest in cryptocurrency projects, and it is also the best way for cryptocurrency project founders to raise funds for platform operations.

9. Views on currency circle K-line:

K-line chart (Candlestick Charts) is also called candle chart, Japanese line, Yin and Yang line, bar line, red and black line, etc. Commonly used sayings It is the "K line". It is plotted as the opening, high, low and closing prices for each analysis period.

10. Trading in the currency circle:

Buying is to buy digital currency from an exchange with a low currency price, and then sell it to an exchange with a high price.

『三』 I want to join the mining circle, is there any good way? Coordinates of the Imperial City

Compared with the currency circle, the mining circle is more high-end. If you don’t believe it, you can ask people around you to know. How many are mined. Individual users have no space, no electricity, no professional knowledge, and the input-output ratio is too low. In places with deep mountains and old forests, where electricity and energy are cheap, we ordinary people simply don’t have these resources. So I suggest you study more, including Golden Finance, Babbitt, Mars Finance, including technology articles.
It is also important to attend some business schools and join the right circles and platforms. As for platforms, such as Youkuang, it is very suitable for novices to learn and practice, and the threshold is lower. Some of their offline meetups can often invite senior people in the mining circle. If you don’t understand anything, you can ask others for advice. I believe that through such systematic Study, and sooner or later you will become a senior expert in the mining industry!

『四』What’s going on with digital currency mining

The wealth myth of “one coin, one villa” is still widely circulated in the currency circle, and new investors are constantly eager to try it. But in fact, from mining machine manufacturers to large mine owners to mining pools, this small circle has formed a stable power structure.

Manufacturing and selling mining machines, mining, building mines, and building mining pools, the "mining circle" has become another way to make a fortune in the blockchain world, and mining machines have also become a little-known " Big business".

According to the vision of Bitcoin inventor Satoshi Nakamoto, the ideal state should be "decentralized", with computing power dispersed around the world. However, contrary to decentralization, mining pools are absolutely centralized, and more and more mining machines are connected to mining pools.

This article was first published on Southern Weekend

“If speculating in currencies is a road of no return, then investing in mining machines is a business that is sure to make a profit, and recovery of costs is only a matter of time. "Zhong Xi, general manager of Shenzhen Aibo Times Technology Co., Ltd., calculated an account. A mining machine earns 200 yuan a day, and it can recover its capital in 120 days, and then it will be profit.

In October 2017, Zhong Xi joined the mining army in addition to his main business, and quickly became a big boss in the mining circle. He operates in Jiangxi, Sichuan, Guizhou and other placesThere are many large mines.

In fact, this "guaranteed profit without loss" business still relies on the continued rise in currency prices. In the past two months, the price of Bitcoin has dropped from US$15,000 to around US$10,000, and even fell below US$6,000 at one point, which has extended the payback cycle of mining machines. If it continues to fall, profits will be far away.

Four years after the advent of Bitcoin, in 2012, mining machines that could be mass-produced appeared. Prior to this, mining was mainly a private activity and could be completed with a home computer. "At that time, home computers were money printing machines, and a lot of Bitcoins could be mined every day." Huang Shiliang, a senior digital currency player who sold mining machines in his early years, recalled to Southern Weekend reporters.

After the emergence of mining machines, mining began to be "socialized". Mines and mining pools appeared, and mining became a collective work. Individual mining machines are hosted by mining farms, just like workers on a production line. As long as they are placed there, they can receive a salary every day.

Manufacturing and selling mining machines, mining, building mines, and building mining pools, the "mining circle" has become another way to make a fortune in the blockchain world, and mining machines have also become a little-known " Big business".

China has become the world’s largest producer of mining machines. Since 2012, a number of mining machine manufacturers have been born in China, such as Shenzhen Bit Spring Co., Ltd., which produces Roast Cat mining machines, as well as the now famous Bitmain, Canaan and Ebrun Communications. In Huaqiangbei, Shenzhen, you can see foreigners everywhere asking about the price of mining machines with translators.

Recently, Bitmain CEO Ketuan Zhan said in an interview with the media that this startup, which was only established for 4 years, had a revenue of approximately US$2.5 billion in 2017. Bitmain is known as the world's largest mining machine manufacturer, and their Antminer machines have always been the hard currency in the currency circle and the miner world.

Similar to the currency circle, the mining circle also requires faith - a firm belief that the mechanical mathematical operations of mining machines every day can create huge wealth.

However, contrary to the "decentralization" promoted by Bitcoin, the world of miners is moving toward "centralization." Mining machine sellers build their own mines, and after investors buy the mining machines, they are hosted by the sellers; while manufacturers build their own mining pools and manage the mines.

This "centralization" process has caused the wealth in the mining circle to be seized by a few people. It is not easy for Zhong Xi to enter the inner circle.

"Centralization" of computing power

The main function of a mine is to provide a place for decentralized mining machines to operate. But what really plays the role of integration is the “mining pool”.

The so-called "mining pool" can be simply understood as "cooperative mining". Miners and mining farms hand over their computing power to the mining pool, which uses the mining pool as the only address to access the digital currency network for mining, and then distributes dividends to the miners according to the computing power of the mining machine.

Mining pools have a longer history than mining machines. In November 2010, a mining pool named Slush appeared. Its official website still states today that it is “the world’s first mining pool.” ThisThis title is also recognized by the currency circle. Compared with mining farms, the establishment of mining pools requires certain skills and the threshold is relatively higher.

The person in charge of a well-known domestic mining pool explained the principles of mining pools to Southern Weekend reporters. He compared mining to buying lottery tickets. If a person mines alone, the probability of winning is very unstable. He may win 100,000 today but not win in the next six months.

“Gather people who buy lottery tickets together and buy them together. No matter who wins, they will be divided according to the proportion of their money. In the currency circle, mining pools play this role.” The person in charge said.

It is not complicated to connect a mining machine to a mining pool. According to the operation guides of major mining pools, it usually only takes a few steps to complete, and then you can get income from the mining pool based on the computing power you provide. A mining machine is like a worker standing on a production line, receiving a fixed salary every day.

Mining pools with huge computing power and numerous mining machines have an absolute say in both the currency and mining circles. For example, if you want to issue a new digital currency or lead a Bitcoin fork, you generally need the support of a mining pool. Without the support of a mining pool, there will be no one to mine the new currency, and it will be meaningless.

In addition, when a popular new coin comes out, the mining pool can also use the miners at its disposal to quickly package it and take the lead in the rush to buy these new coins.

In June 2017, when the two major tokens SNT and EOS were issued, Southern Weekend reporters witnessed the scene of mining pools snapping up tokens. Because there are too many investors, many individual investors are unable to put funds into a designated location, but the person in charge of a mining pool can easily complete this operation.

According to the vision of Bitcoin inventor Satoshi Nakamoto, the ideal state should be "decentralized", with computing power dispersed around the world. However, contrary to decentralization, mining pools are absolutely centralized, and more and more mining machines are connected to mining pools.

On January 18, 2018, five people including Cornell University computer professor Emin Yun Sirash co-authored a paper pointing out the existence behind the two major digital currencies Bitcoin and Ethereum. Hidden power structure, mining is too concentrated, with 50% of Bitcoin’s computing power controlled by the four major mining pools.

In fact, this problem has always existed. Four years ago, Ethereum founder Vtalik noticed this problem when he wrote the Ethereum white paper. He wrote: "This problem can be said to be very serious. At the time of writing this article, the two largest mining pools indirectly control about 50% of the computing power of the entire network.”

To this day, this problem has not been solved. An early translator of the Ethereum white paper said helplessly to a Southern Weekend reporter: "This is not a technical problem, but a human problem."

Implicit power structure

In the mining industry, the top level of the food chain is the mining machine manufacturer. Currently, the three major recognized mining machine manufacturers are all located in China. They have made a lot of profits by producing and selling mining machines. They are also involved in the construction of mines and mining pools, and have a say in the entire currency circle.

Ant Pool is a global rankingThe top two large mining pools account for 17% of the entire network's computing power. However, according to industrial and commercial data, this mining pool was founded by Bitmain; several investors of Canaan Mining are also members of the Hangzhou Mining Pool. An investor in Technology Co., Ltd., which has its own mining pool Hash and mining platform, but the mining pool ceased operations at the end of 2017.

Yibang Communications has established three blockchain companies in Hohhot and Wuhai City, Inner Mongolia, and Xinjiang Zhundong Economic Development Zone. A salesperson from Ebrun Communications told Southern Weekend reporters that they have mines and mining operations in these three places, but these mines are also operating at full capacity and there is no room to host new mining machines.

“We are building a new mining farm in Irkutsk, Russia, where electricity costs are much lower and new mining machines can be hosted there,” the person said.

Beyond the mining machine manufacturers, it is the chip giants that are harvesting. "The core technology of mining machines is on the chip. Whoever has mining machine chips can produce more mining machines." Ding Yang told Southern Weekend reporters that chips are mainly in the hands of several giant manufacturers, such as TSMC, Nvidia, and AMD. wait.

Since 2015, TSMC has been Canaan’s largest chip supplier. In 2015, the chips purchased by Canaan Intelligent Technology from TSMC accounted for 69.62% of all purchases by Canaan Intelligent Technology. Since then, this figure has remained at around 60%. Most of Canaan Intelligent's profits were earned by TSMC.

On January 18, 2018, at the briefing of TSMC’s fourth quarter financial report, Chairman Zhang Zhongmou said that although the mobile business prospects this year are weak, the company’s revenue will still grow by 10%. —15%, one of the key factors is continued solid demand for chips from cryptocurrency mining.

Under the mining machine manufacturers, there is another power structure hidden. Canaan's 2017 prospectus revealed this secret. In the first four months of 2017, four of Canaan's top five customers were "individuals." According to public information, three of them are well-known "wrongs" in the currency circle.

The so-called inverse contract is also called a currency-based contract, which is priced in USD, and the margin is collected and the profit and loss is calculated in the corresponding digital asset currency. Forward contracts are contracts that are priced in USDT and use USDT as margin and calculation of profit and loss.

『8』What is the difference between currency circle and chain circle

Chain circle”, “coin circle”, “ Many people are confused about the "mining circle", but aside from those connections, the essence of the three is actually quite different. In the blockchain ecosystem, it is currently roughly divided into three circles, namely "chain circle" and "coin circle". "Chain Circle" and "Mining Circle". The three are related to each other, but they are also very different.
Chain Circle - Chain Circle, the representative of the technical group. The threshold is higher than the other two circles, and it mainly focuses on the area. Blockchain technologydevelopment and application, so it is relatively difficult for ordinary people to step into it.
Blockchain can be divided into three stages: private chain, public chain and alliance chain.
Coin Circle - The currency circle can be said to be the most colorful circle. Focusing on speculating in encrypted digital currencies, it is the circle with the lowest entry barrier among the three circles. The main characteristics are currency issuance and speculation. Coins issued based on blockchain technology are mainstream currencies, such as Bitcoin, Ethereum, etc., with less risk. The coins issued by ICO are altcoins, which have certain risks. The hype is caused by the lack of supervision in the industry and common back-end trading. Currently, ICO has been banned in my country.
Mining Circle - Mining Circle is a circle of people who focus on "mining". This mining is different from mining in life, but an act performed to obtain virtual currency rewards. People who participate in mining are called miners.
Mining requires the use of tools. In the early days, mining could be done through ordinary computers. Later, as the number of miners continued to increase, it began to develop into mining machine mining and mining pool mining. Mining requires high costs, such as huge power consumption, and electricity bills are also a large expense.
The threshold of the mining circle is slightly higher than that of the currency circle, but lower than that of the chain circle. Most people have heard of mining, but there are still fewer people who actually participate in mining.
Compared to the chain circle and the currency circle, the mining circle is also affected by the external natural environment, such as damage to the mining machine in the mine.
In the current context, it is meaningless to hype the concept of blockchain. Blockchain practitioners must find ways to contribute value to this society and create wealth instead of evaporating wealth. Therefore, we do not distinguish between currency circles and chain circles. Those who can create value are good circles.
