Analog 激励测试网教程(更新合约部署）

简介

Analog 是一个完全去中心化的第 0 层平台，用于通过时间证明共识机制传达经过验证的事件数据。该平台的核心是 tesseracts 和时间节点，它们可以从主权链私下获取和确认事件数据，允许不同的生态系统使用相同的语言。 Analog旨在引入无需信任的全链互操作性，允许开发人员通过通用协议和API轻松构建他们的应用程序。 Analog 还推出了一种新颖、超快的 PoT 协议，该协议在时间链上创建可验证的事件数据，允许 DApp 开发人员构建下一代基于事件的应用程序。

融资情况

Analog完成了由Tribe Capital领投，NGC Ventures、Wintermute、GSR、NEAR、Orange DAO、Mike Novogratz 的另类资产管理公司 Samara Asset Group、Balaji Srinivasan 等参投的1600万美元种子轮及战略轮融资。

空投预期

代币分配：ANLOG的总供应量上限为90,579,710。总供应量的一定比例将在主网启动时铸造，剩余的代币将在未来几个月内归属，并按以下方式分发：

种子轮 26.8% 线性分发27个月

机构投资#1 1.9% 线性分发24个月

机构投资#2 0.5% 线性分发24个月

机构投资#3 0.6% 线性分发18个月

机构投资#4 0.5% 线性分发18个月

私募 10.1% 线性分发24个月

战略投资 3.7% 线性分发18个月

团队/顾问 15.4%

资金 14.6%

社区 26%

-市场 4.5%

添加网络并领水

以SubWallet钱包为例（建议第二个方法添加）

在URL处填写：wss://rpc.testnet.analog.one 然后保存即可

钱包首页下拉找到添加的代币，进入复制地址

或者前往（推荐此方法）：

https://watch.testnet.analog.one/#/

链接钱包

链接好钱包之后点击右上角的钱包，复制第2个an开头的地址即可

前往DC的**#faucet**频道输入：!faucet+钱包地址领水

交互流程

前往

https://testnet.analog.one/#/?signup&referral=YJCC50

注册账号

绑定EVM钱包

然后点击银河链接，跳转至银河页面，完成社交任务即可

完成银河任务之后返回任务页面，Claim积分即可

WATCH GAME栏任务，需要在有会议和投票的时候才可以参加并获得积分，等待任务不定时开启

开启WATCH GAME之后，进入，点击START VOTING

任意挑选一个投票

完成之后WATCH GAME栏积分增加10，获胜后可以得到更多积分（建议大家都投票给1号）

Developer任务栏

剩下的任务是合约部署和bug反馈这类的开发者任务，能力有限，需要花时间研究，完成后更新

部署一个智能合约

前往Remix

Remix - Ethereum IDE

https://remix.ethereum.org

新建一个.sol文件（名字任意）

复制以下代码填入：
