With Partiko, you can easily see what’s going on in the Steem community, make posts and comments (no beneficiary cut forever!), and always stayed connected with your followers via push notification!\n\nPartiko also rewards you with Partiko Points (3000 Partiko Point bonus when you first use it!), and Partiko Points can be converted into Steem tokens. You can earn Partiko Points easily by making posts and comments using Partiko.\n\nWe also noticed that your Steem Power is low. We will be very happy to delegate 15 Steem Power to you once you have made a post using Partiko! With more Steem Power, you can make more posts and comments, and earn more rewards!\n\nIf that all sounds interesting, you can: \n\n- Download Partiko Android at [Google Play](http://bit.ly/2SRFIta)\n- Or Download Partiko iOS on the [App Store](https://apple.co/2PcXkSd)\n\nThank you so much for reading this message!",

      "body": "# 达芬奇技术\n\n## 目标\n达芬奇的目标是通过人工智能技术构建可以99.9%完美控制MainNet的系统. 目前的区块链系统存在客户端和DApp间的通信窃取问题,以及DApp和中央服务器的通信黑客问题,无法用现有的普通技术解决. 理由是因为客户通过应用软件接触信息,为了产生新信息,必须以DApp ←→ Block Chain, Block Chain ←→ Main服务器的交流为前提. 这可以说是PoW系统及PoS系统都具有的根源问题. 达芬奇希望通过人工智能和Side 链解决这些问题. \n\n![mainnet_01.png](https://cdn.steemitimages.com/DQmWyLXeTvdrmYe98m3p2hV3NUyhKd75AQG7ntbopQKmPbP/mainnet_01.png)\n\n即,通过人工智能的集体智慧功能解决公正性是非和速度问题. 集体智慧是在学习主网的多种情况后形成的。其结果是,根据彻底的规则启动的人工智能区块链系统被驱动. 把它想成维护交通秩序的无人汽车系统可能会简单一点.\n\n### 人工智能系统的定义\n人工智能是自动监督和管理节点动作的系统,类似于完全不需要人手的无人汽车系统.\n\n### 那么人类干预的部分是? \n人类对主要议题的人工智能评价分为紧急主题和定期主题,通过投票决定. 这是人与人工智能可以相互补充的事情.\n\n###  达芬奇在 ASTER AI Machine内搭载了2种引擎.\n• 客户倾向分析 Engine \n• AI Cube Learning Engine\n\n客户的趋向分析引擎根据各DApp的不同,由不同的程序构成。因此各自适用的算法不同,将在各DApp文件中进行说明. \n\n### AI CUBE Learning Engine具有两种功能.\nⓐ 生成客户(DApp 用户) 认证 Chain \n达芬奇为提高整体区块链生成及维持的效率,分为链上(Onchain)系统,侧链(Sidechain)系统来运营系统。链上是指发生节点的生成、扩张等, 形成区块的链接的一般性区块链系统,侧链是指与链上不同的链接, 同时也是可以与链上进行交流的链接系统.\nDApp 用户的注册及认证程序是一种Offchain状态,因此用户的信息被生成, 在Onchain上注册的过程中可能会发生信息被窃取的情况. 将此细分为用户认证+ Sesion生成阶段后, 利用生成的session, 应用在Onchain中可以生成、登记用户节点的方法, 可从根本上防止信息被窃取. 其结构如下图.\n\n![mainnet_02.png](https://cdn.steemitimages.com/DQmU9nyFEmfTP7uwvE3qU4aAKiW41NkBD8rcuy4qqgnhpUN/mainnet_02.png)\n\n### 用户注册会员时, X.509认证书最初生成并发放一次. \n生成的认证书将无TTP(Trusted Third Party),去中央化并被保存,日后相同账户的认证书生成邀请将被全部退回. 用在认证书电子签名上的private key,通过用户密码和salt值来hashing,生成1024byte长度的密码,用户密码不单独保存在系统内,认证书 用户须通过去中央化的Certificate Authority Chain才能保存。用户必须通过去中央化的认证书才能获得，对话在Session Chain中则可以自动共享,因此无法进行伪造更改. \n\nⓑ Dapp中生成的信息的密码化作业 AI CUBE Learning Engine的另一个功能是 DApp 和 ASTER Server间的交易信息加密. 将用户的DApp使用信息,与其他用户的通信信息,Token相关信息等加密化,将ASTER AI Machine中使用的所有与用户相关的信息进行加密. 因此可以将DApp与ASTER AI Machine间的通信过程中可能发生的黑客侵入无效化.
\n\n 达芬奇将本 MainNet高度高度化至Onchain, Sidechain Complex,在用户节点的生成、运营与使用户之间的代币奖励程序中,具有效率性和稳定性(安保完整性).",

Although unions cooperated with the government and pledged not to strike, many non-unionized workers went on strike during the war years—indeed, there were more strikes during the World War Two years than in “any comparable period in American history.” \nWar benefitted the American elite by providing businesses with lucrative contracts for cars, guns, and planes. In response to the growing power of the Establishment, American unions—according to Zinn, many of them, though he doesn’t provide exact numbers—protested against American capitalism. \n\nIt was a war waged by a goverment whose chief beneficiary despite volumes of reforms-was a wealthy elite\nThe alliance between big business and the goverment went back to the very first proposals of Alexander Hamilton to Congress after the revolutionary war. by the deression, Roosevelt had once denounced the economic royalists but he always had the support of certain important business leaders. during the war , as Bruce Catton saw it from his post in the war production board\nThe economic royalists denounced and derided/had a part to play now\n\nreference : people's histody of America, Howard Zinn",
