1, block chain where the "family":
The core point: + decentralized Internet:
Decentralization: Decentralization
Edge computing:
That three league:
P2P Download: [shared user disk] + CDN: [] + broadband users to share distributed computing: shared CPU resources []
P2P Download: [shared user disk]
In 1999, Shawn Fanning founded mp3 music sharing site Napster's called, he is also one of the first consultants, investors and shareholders Facebook.
Napster itself does not own MP3, which can be found on each user's one song where the disk, and then require the user to download songs from the resources of each of the other user's disk.
P2P download copyrighted great impact on the United States and later prohibited in this way to share MP3, Napster also declared bankruptcy in 2002.
The nature of P2P, sharing a hard drive, is the hard disk on the part of everyone's computer, out to share with others.
CDN: [users to share broadband]
Access to different areas of the same resources (such as video with larger bandwidth resources), different paths, different access rate;
To solve this problem, the same resources were placed in several areas, through CDN technology, users can access its nearest resources.
Namely: distributed storage, distributed shared bandwidth
Evolutionary version: P-CDN
Each user's computer have become CDN
Thunder out of a product to make money treasure, later called the play-off coins, use is P-CDN;
Distributed computing: shared CPU resources []
The password cracking computing tasks into a number of blocks, respectively, using a plurality of user-task processes a respective module;
This is much faster than the centralized supercomputers;
Distributed computing: put the work requires a lot of calculations, for example, code-breaking, or calculate a DNA sequence, broken down into numerous small pieces.
On the edge of the calculation:
In the past we provided through the cloud computing resource sharing, cloud computing is one of our distant relative, is to provide a giant, cloud computers away to everyone through the Internet.
Edge computing, that is, using a shared disk, shared power and shared network operators, virtual computer; that's distributed cloud computing
social media
Traditional media are centralized, say rests in the hands of individuals.
Social media is the right to speak to each participant; everyone's voice can be heard by other people;
Representatives: Facebook, Twitter, Weibo, Tencent;
P2P lending [the most controversial and risky]
Traditional lending, the bank is funding by user A, user B through higher lending rates, banks earn high interest rate differential.
P2P lending that banks set aside, the center of factors, avoid direct brokers to make the difference;
P2P lending is currently several decentralized philosophy, by the most controversial issues, risk, and indeed help a lot of people to borrow money.
There are financial risks crowdfunding []
United States on behalf of a company: Angel list
In the past we are to look for venture capital financing, or go to the market, these are the methods of financing of the center. In fact, agencies or stock market money is invested countless people to, then if a company needs money, can go directly to these scattered investors borrow it?
In China more than 200 people called illegal fund-raising, we can not be within 200 person, find someone who has the ability to identify risk and affordability, to take their money without going through intermediaries it? We refer to this method is called crowdfunding
On behalf of the enterprise: the United States Uber, the first round of financing is through the angel list obtained;
Crowdfunding combined with tokens, hatched a product: ICO
Tokens, coins bit prototype;
ICO (Initial Coin Offering is abbreviated), the first coins issued from the stock market's initial public offering (IPO) concept is a block chain project was first issued tokens, raising behavior Bitcoin, Ethernet Square and other general-purpose digital currency.
ICO是一种区块链行业术语，是一种为加密数字货币/区块链项目筹措资金的常用方式，早期参与者可以从中获得初始产生的加密数字货币作为回报。由于代币具有市场价值，可以兑换成法币，从而支持项目的开发成本。ICO所发行的代币，可以基于不同的区块链。常见的是基于以太坊（ETH）和比特股（BTS）区块链发行，由区块链提供记账服务和价值共识，实现全球发行和流通。
-
都有通过出售股份来筹措资金；
-
都有潜在投资者为了潜在的巨大收益而冒险参与。
-
ICO的大部分支持者是项目爱好者或不专业的投资者；
-
ICO不需要注册经营牌照；
-
ICO平台是第三方中立平台，投资者自担风险。
代币及ICO在中国是被禁止的
2017年9月4日下午3点，中国人民银行领衔网信办、工信部、工商总局、银监会、证监会和保监会等七部委发布《关于防范代币发行融资风险的公告》
区块链
创始人，中本聪；
中本聪在2008年发表了一篇论文，这篇论文的标题叫做《基于点对点技术的数字现金系统》
第一是基于点对点技术，点对点就是我的父亲，也就是P2P。
第二个叫做数字现金，digital cash。digital cash和digital currency是有很大区别的。currency是货币，货币不只是现金。而数字现金系统是一个很窄的领域。
数字现金，利用点对点技术实现记账能力；分布式记账技术；
分布式记账，即每个人都拥有相同的账本，记录全网的数据，这个记录数据量极大，这也是分布式记账的缺陷；
分布式记账的缺陷导致，分布式记账只能应用在数据量特别小的领域；
比特币
比特币是区块链技术的具体应用实例；
基于分布式记账技术的一种数字现金。比特币是模拟黄金来发行的，2100万枚的总量，每4年开采量就会减半
去中心化，在全世界不需要任何央行的数字现金体系，能够把全世界的金融体系，变得更加透明。
DOA 去中心化组织（自组织）
传统的管理层级，高层、中层、底层，带来的问题，是沟通的效率极低；
DOA解决的就是提高整个人类直接的沟通效率；
DOA还未诞生，或叫做未成功出现；正在酝酿着；
