Ethereum Smart Contracts in Solidity for DApp CITIZEN project

Presentation

DApp CITIZEN is a project to create a token economy and manage a fictional country and its citizens by deploying smart contracts on Ethereum blockchain written in Solidity :

Token.sol handles the token
Government.sol handles State Affairs.

• contracts inherit from Open Zeppelin’s ERC777 and Ownable already tested contracts and use SafeMath library
• testing done using Mochatest framework, Chai assertion library and Open Zeppelin’s Test Environment and Test Helpers
• deployment via Truffle on Rinkeby Testnet
• comments using NatSpec format who generate documentation via solidity-docgen

Install

Install dependencies:

% yarn install

Add environment variables:

Add .env file with 2 variables MNEMONIC and ENDPOINT_ID from Infura

Details of the project

token CITIZEN

A token called CITIZEN (symbol CTZ, 18 decimals) serves as national currency and citizenship point inside this country.
100 CITIZEN are automatically awarded to any individual who wishes to become a citizen.
An entity called sovereign is the owner of the state, has the right to register and unregister companies and hospitals, denaturalize citizens and is minted, during token contract deployment, 100% of the supply of CITIZEN (1 million CTZ). The owner retains the right to burn or mint tokens CTZ in the future in order to regulate the economy.

Companies

To function a company must be registered by the sovereign using its Ethereum address. It can then buy CTZ from the sovereign.
A company can recruit employees from the registered citizens, pay them salaries in CITIZEN tokens and dismiss them.

Hospitals

To function a hospital must be registered by the sovereign using its Ethereum address.
A hospital can change the health status of a registered citizens between healthy and sick, and also can declare dead a citizen.

The citizens

The citizens are identified by their Ethereum address and can have different properties:

• alive / dead
• healthy / sick
• working / unemployed
• an employer
• a date when it’s possible to ask for retirement etc.

A citizen has also a balance of CTZ spread between his current account, unemployment insurance, health insurance and retirement insurance. Only the current account is at his disposal.

Life events :

• When becoming citizen, he is awarded 100 CTZ in his current account.
• When receiving a salary from his employer 10% of the salary go to his unemployment insurance, 10% to his health insurance, 10% to his retirement insurance and the remaining 70% to his current account.
• When being dismissed by the employer all unemployment insurance tokens are transfered to his current account.
• When being declared sick by a hospital all health insurance tokens are transfered to his current account.
• When requesting for retirement (if has reached retirement age) all unemployment insurance and retirement insurance tokens are transfered to his current account.
• When being declared dead by a hospital all his tokens are given back to the sovereign.

演示

DApp citide是一个通过在以太坊eth区块链blockchain上部署以Solidity编写的智能合约来创建代币经济和管理虚拟国家及其公民的项目：

令牌.sol处理令牌
政府.sol处理国家事务。

• 合同继承自Open Zeppelin的ERC777，可拥有已测试的合同，并使用SafeMath库
• 使用Mochatest框架进行测试，通过在健康/无业环境中使用工作环境的通过工作环境生成健康/无业测试当有可能要求退休等情况时，当他成为公民时，他将在其经常账户中获得100 CTZ。当雇主给他发工资时，工资的10%给他的失业保险，10%的健康保险，10%的退休保险，剩下的70%存入他的经常账户。当他失业时，所有的失业保险金都被雇主解雇了。
• 当医院宣布生病时，所有的健康保险代币都会转到他的活期账户。
• 当申请退休时（如果已达到退休年龄），所有失业保险和退休保险代币都将转入其活期账户。当被医院宣布死亡时，他所有的代币都会归还给君主。在

项目详情

从Infura添加带有两个变量助记符和端点的.env文件，18位小数）作为国家货币和公民身份点数。
100位公民将自动授予任何希望成为公民的个人。
一个名为主权的实体是国家的所有者，有权注册和注销公司和医院，使公民变性，并在代币期间铸造合同部署，100%市民供应（100万箱）。业主保留在未来焚烧或铸造代币的权利，以监管经济。

代币公民

公司

要运行公司，必须由主权国家使用其以太坊eth地址进行注册。公司可以从注册公民中招募员工，用公民代币支付工资，然后解雇他们。

医院

要运行医院，必须由君主使用其以太坊eth地址进行注册。
医院可以在健康和疾病之间更改注册公民的健康状况，也可以宣布死亡为公民。

市民

公民通过以太坊eth地址进行识别，并且可以拥有不同的属性：

基本Cookie

公民的经常账户、失业保险、医疗保险和退休保险之间也有CTZ利差余额。只有往来账户由他支配。

• alive / dead
• healthy / sick
• working / unemployed
• an employer
• a date when it’s possible to ask for retirement etc.
