如何使用 ZeppelinOS 產生 ERC20 tokens

本期不寫 Code

讓我們在 Ropsten Test net 上測試，用 ZeppelinOS 直接產生 ERC20 tokens。

先安裝與架設好 zos for Rosten network deployment：

cd /tmp && mkdir my-app && cd my-appnpm install yarn zoszos init my-app 1.0.0zos link openzeppelin-zos

rm truffle-config.js && wget https://gist.githubusercontent.com/…/1be8…/truffle-config.js

yarn add openzeppelin-zos truffle-hdwallet-providerzos push --network ropsten

然後執行以下指令，假設你在 Ropsten 有一個帳號 ，例如這裡的 0x66ee73086134f147745be72335153bf780499e2e，當成這 tokens 合約的所有人，您可更改 muzha 成你要的 token 名稱，以及改 MUZA 成你要的 token 符號。

只要一行指令, 就可以生成 tokens：

在 /tmp/my-app 目錄下

OWNER=0x66ee73086134f147745be72335153bf780499e2e zos create DetailedPremintedToken --init initialize --args $OWNER,muzha,MUZA,8,100000000000000000000 --network ropsten

結果如下，就可以產生一兆個 ERC20 tokens，合約位址在 0xc634d06c9d0fac3c6b341dc6238a15f253caecf9

Creating DetailedPremintedToken proxy and calling initialize with: - _sender (address): "0x66ee73086134f147745be72335153bf780499e2e" - _name (string): "muzha" - _symbol (string): "MUZA" - _decimals (uint8): "8" - _initialBalance (uint256): "100000000000000000000" TX receipt received: 0x6aa11e9a8465092ee17642703aeec1272e1dda452a028da1f460bbcd75dac6d8 DetailedPremintedToken proxy: 0xc634d06c9d0fac3c6b341dc6238a15f253caecf9Successfully written zos.ropsten.json

可以利用 Ropsten 的 Etherscan 做驗證如下：

安裝 zos 與 truffle 這麼麻煩，乾脆用 docker，結果是一樣的：

docker run mingder78/create-erc20-token 0x66ee73086134f147745be72335153bf780499e2e,TaiwanNewToken,TNT,8,100000000000000000000

$ docker run mingder78/create-erc20-token 0x66ee73086134f147745be72335153bf780499e2e,TaiwanNewToken,TNT,8,100000000000000000000Creating DetailedPremintedToken proxy and calling initialize with: — _sender (address): “0x66ee73086134f147745be72335153bf780499e2e” — _name (string): “TaiwanNewToken” — _symbol (string): “TNT” — _decimals (uint8): “8” — _initialBalance (uint256): “100000000000000000000” TX receipt received: 0xfa424db886ea3bcdfa79bed262c41b82b2a028dfdc240bfb47e067ae34ae4aa6 DetailedPremintedToken proxy: 0x5e19e1830d452e64157c3a49978607f02d79bbf8Successfully written zos.ropsten.json0x5e19e1830d452e64157c3a49978607f02d79bbf8

#科技 #Mac
介紹Mac專用的套件系統(就是像ubuntu的apt-get)：
http://brew.sh/index_zh-tw.html
可以用來裝一些系統沒有的元件～(啥joe或是wget之類的)
http://caskroom.io
然後再裝這個cask擴充套件，就可以用來安裝GUI的App…
之後就只要用指令就能裝應用程式了～完全不用自己去下載安裝檔跟點安裝～

入手新Mac，安裝完新系統後，重新建立工作環境中，順便記錄一下自己裝了哪些套件：

- ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
- brew install caskroom/cask/brew-cask
- brew install joe
- brew install wget
- brew cask install firefox
- brew cask install google-chrome
- brew cask install flash-player
- brew cask install dropbox
- brew cask install 1password
- brew cask install xtrafinder
- brew cask install sublime-text
- brew cask install iterm2
- brew cask install google-drive
- brew cask install xmind
- brew cask install nally
- brew cask install synology-cloud-station
- brew cask install filezilla
- brew cask install microsoft-office
- brew cask install adobe-photoshop-cc adobe-illustrator-cc
- brew cask install diskmaker-x
