无论是区块链1.0、2.0、3.0，都会涉及到共识机制。因为所有的公有链都是社区自治，没有中心领导来决策，为了维护公有链，必须多数社区用户达成一致意见。而如何达成，就是共识机制。目前区块链采用的共识机制主要有工作量证明机制(POW)、权益证明机制(POS)、委托权益证明机制(DPOS)。

Whether the block chain is 1.0, 2.0, or 3.0, the consensus mechanism is involved. Because all the public chain is community self-governing, there is no central leadership for decision-making, and in order to maintain the public chain, the majority of community users must agree.

比特币采用工作量证明机制(POW)，随着算力的上涨，挖矿难度越来越大，对于资源的使用量也越来越大。为了弥补这一缺陷，权益证明机制(POS)应运而生。这种共识机制的优点是可以避免能源消耗，但缺点是话语权都被持币大户所掌控，形成中央集权的特征，也与区块链去中心化的初衷背道而驰。随着而来的，EOS号称是区块链的3.0，采用的共识机制是委托权益证明机制(DPOS)。

Bitcoin uses the Workload Certification Mechanism (POW), which increases the difficulty of mining and the use of resources as a result of rising computing power. To remedy this deficiency, the Proprietary Proprietary Mechanism (POS) was created. The advantage of this consensus mechanism is that it avoids energy consumption, but the disadvantage is that speech rights are controlled by large money-holders, forming a centralization feature that runs counter to the original intent of decentralizing the block chain.

委托权益证明机制(DPOS)是社区自治的，由社区所有持币人共同投票选出21个超级节点。由这些超级节点代理持币人验证和记账;而这些超级节点的权利是相等的;DPOS就像董事会投票，持币者投出一定数量的节点 (董事);代表按照既定时间表，轮流产生区块，如果代表没能很好的行使权力(比如产生区块)，他们会被除名，网络会选出新的超级节点来取代他们;所有的代表将收到平均水平区块所含交易费的10%作为报酬。这就是EOS采用的共识机制。

The trust equity certification mechanism (DOS) is community self-governing, with all of the community’s currency holders voting together to select 21 super-nodes. These super-nodes represent the currency holders for validation and accounting; these supernodes are equally entitled; the DPOS vote is like a board vote, and the currency holders cast a certain number of nodes (Directors); delegates produce blocks on a rotating basis according to the established timetable, and if representatives fail to exercise their authority (e.g. by producing blocks), they are removed, the network selects new supernodes to replace them; all delegates are paid 10 per cent of the transaction costs contained in the average block. This is the consensus mechanism used by EOS.

1、EOS 有点类似于微软的windows平台，通过创建一个对开发者友好的区块链底层平台，支持多个应用同时运行，为开发DPOS提供底层的模板。

1. EOS is a sort of Microsoft-like Windows platform that supports the simultaneous operation of multiple applications by creating a bottom-of-the-developing block chain platform that is friendly to the developers and provides a bottom-of-the-ground template for the development of DOS.

2、EOS通过并行链和DPOS的方式解决链延迟和数据吞吐量的难题，EOS是每秒可以百万级别的处理量，而比特币每秒7笔左右，以太坊是每秒30-40笔。

EOS solves the problems of chain delay and data through parallel chains and DOS, which is a million-degree processing volume per second, while Bitcoin is about seven times a second, and the Tails are 30-40 times a second.

3、EOS是没有手续费的，普遍受众群体更广泛。EOS上开发DPOS，需要用到的网路和计算资源是按照开发者拥有的EOS的比例分配的。

EOS is free of charge and has a wider audience.

EOS通过社区推选出来的可信账户(受托人)来创建区块。这种机制类似于股份制公司，普通股民不能充当决策者，所以需要通过投票选举的方式，推选出代表来替他们做决策;在EOS系统中，受托人就是普通用户推选出来的代表，他们充当的是区块生产者的角色。

EOS creates blocks through credible accounts (trustors) selected by the community. Such mechanisms are similar to stock companies, where ordinary stockholders cannot act as decision makers, and therefore require representatives to be elected by means of voting; in the EOS system, trustees are representatives chosen by ordinary users, who act as block producers.

EOS是一个社区决策驱动的项目，因此超级节点的数量并非一成不变，若超级节点的数量不再能够满足项目的发展，则社区成员可以投票增加超级节点的数量。提交申请初步筛选后先成为备选节点，然后获得一定的社区投票数后才能当选为超级节点。技术规范评估必须要谨慎，且所有评估都要认真核对，EOS社区会对评估结果的质量和可靠性进行评价审核。

EOS is a community-driven decision-making project, so the number of supernodes is not constant, and if the number of supernodes is no longer sufficient to meet the project’s development, community members may vote to increase the number of supernodes.

EOS 系统有一个硬性的条件，即每年产生的新代币数量不能超过代币总量的 5%。也有言论称新产生的代币中 50% 归 21 个超级节点，另外 50% 归其余 100 个候补节点。

The EOS system has a rigid condition that the amount of new currency generated per year cannot exceed 5% of the total number of the tokens. There are also claims that 50% of the newly generated coins fall into 21 supernodes and 50% into the remaining 100 alternate nodes.

EOS并不是像比特币和以太坊那样的货币，而是基于EOS软件项目之上发布的代币。可以说 EOS 整个系统的价值，就完全维系于这 21 个超级节点和 100个候补节点之上。成为超级节点获得的直接收益来自区块生产奖，EOS 中的超级节点不需要完成全部工作量来证明，可以直接广播区块到网络中，让其他节点进行验证。一旦一个节点完成了区块生产并通过其他节点的验证，它就可以将这个区块添加到区块链上，并获得新的代币作为出块奖励。

EOS is not a currency like Bitcoin and Etheria, but is based on a token issued on the EOS software project. It can be said that the value of EOS as a whole is fully attached to the 21 supernodes and 100 alternate nodes. The direct benefit of becoming a supernode comes from the block production prize, and the EOS supernode does not have to complete the full workload to prove that it can broadcast blocks directly into the network, allowing other nodes to be validated. Once a node has been produced and validated by other nodes, it can add the block to the block chain and receive a new token as an incentive.

首先ETH作为最初推出智能合约的，在ETH上运行智能合约，不是免费的，且取决于你的gas，如果一旦gas耗尽，合约也就停止。据使用过的人说，ETH交易平台运行慢且卡，并且很贵。但是EOS就不存在这方面的问题，EOS上运行合约，取决于你的EOS的数量。你拥有的EOS越多，可租赁的就越多，获得的回报越丰厚。其次EOS上开发DPOS是很简单的，不需要自己写很多的模块，因为本身EOS就为开发者搭建了底层模块，其提供一个平台，大大降低了开发的门槛;在此，做为一个普通的投资者，拥有了EOS就相当于拥有了地皮房产，可以用来出租，赚取资金。

First, ETH, as an initial intellectual contract, does not operate on ETH free of charge, and depends on your gas, and if Gas runs out, the contract stops. According to the people who used it, the ETH trading platform is slow and cardy and expensive. But EOS does not have problems with this, depending on the number of EOS. The more EOS you have, the more you can lease, the greater the return you get. The second EOS is simple and does not need to write a lot of modules on your own, because it provides a platform for developers, which significantly lowers the threshold of development; here, as an ordinary investor, having an EOS is equivalent to having a real estate, which can be used to rent, earn money.

Dan Larimer 认为应该将生产奖励分为三部分，分别作为，超级节点区块生产奖励、备用节点奖励、新提案奖励，具体比例尚不清楚。EOS 代币代表的是 EOS 生态中带宽，算力，存储空间等资源的使用额度。建设好生态，吸引开发者开发优质应用，有越来越多的业务在 EOS 区块链上开展，EOS 上的资源才会成为一种稀缺品，从而支撑起 EOS 代币的价格，让它 to the moon。

Dan Larimmer argues that production incentives should be divided into three parts, as supernode production incentives, stand-by node incentives, new proposal incentives, which are not yet known. EOS tokens represent the amount of use of EOS eco-bandwidth, arithmetic, storage space, etc.
