技术小白如何在EOS上发行通证(TOKEN)?

如何在EOS上发行通证(TOKEN)

1. 本文目标

在EOS私链环境发行TOKEN代币,并进行转账交易。

【技术收获】

1) 创建自有代币 2) 发行自有代币 3) 代币转账操作

2. 操作内容

【环境前置条件】

1)已搭建好EOS私链环境(可参考 第4课 如何在UBUNTU虚拟机上编译EOS完成环境搭建? ) 2)会进行相关钱包账号的操作( 参考 第5课 EOS环境搭建入门(私链节点-钱包-密钥-账号) ) 3) 本文操作时已存在以下资源信息 1] 钱包名称 duncanwang, 对应的解锁密码 为"PW5JYSZRvSropLhguyxYY1zXgeQidSZnRKPKUXr2JUVTYay2zhuxT" 2] 系统私钥/公钥对已导入钱包: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV / 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

本文的操作内容的流程图如下所示:

2.1 创建账户

创建3个账号,eosio.token账号用于创建ColorBayToken代币,wangdenghui账号用于发行代币,创建账户ouyanggege用于接收代币。 创建eosio.token账号

cleos create account eosio eosio.token EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

输出内容:

创建wangdenghui账号

cleos create account eosio wangdenghui EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

2.2 部署代币合约

cleos set contract eosio.token build/contracts/eosio.token -p eosio.token

参数说明: -p,--permission TEXT 表示授权账号,该合约授权给eosio.token账号。 代币合约eosio.token能让许多不同的代币同时在一个智能合约上发行,但是却能被不同用户管理。

duncanwang@duncanwang:~/eos$ cleos set contract eosio.token build/contracts/eosio.token -p eosio.token
Reading WAST/WASM from build/contracts/eosio.token/eosio.token.wasm...

warning: transaction executed locally, but may not be confirmed by the network yet

2.3 创建一个代币

cleos push action eosio.token create '[ "eosio", "1000000000.0000 CBT", 0, 0, 0]' -p eosio.token

参数说明: 1) create 函数是用来新建一种代币,并输入代币的各种属性,同时 create 函数也是一个 action。action 是 eos 智能合约的接口函数,定义外界可以对智能合约做什么动作。 结合操作命令,说明各个参数的定义: create( account_name issuer,/ 发行方账号的名称为"eosio" / asset maximum_supply,/ 总供应量为10亿和代币名称CBT (ColorBayToken的缩写) / uint8_t can_freeze,/ 资产是否可以冻结,0表示否 / uint8_t can_recall,/ 资产是否可以召回,0表示否 / uint8_t can_whitelist );/ 资产是否可以设置白名单,0表示无 / 2)-p,--permission Type: Text - 授权给账号eosio.token

duncanwang@duncanwang:~/eos$ cleos push action eosio.token create '[ "eosio", "1000000000.0000 CBT", 0, 0, 0]' -p eosio.token
executed transaction: 791687224acb86a715639af9b3b4660ac06ac07908c8746851382be661218739  120 bytes  4703 us
##   eosio.token <= eosio.token::create          {"issuer":"eosio","maximum_supply":"1000000000.0000 CBT"}
warning: transaction executed locally, but may not be confirmed by the network yet

2.4 发行代币

cleos push action eosio.token issue '[ "wangdenghui", "10000.0000 CBT", "first ColorBayToken issue" ]' -p eosio

参数说明: 1) issue 函数是用来增发代币,eosio.token 合约并不是新建了代币就会得到代币,新建的代币只是存储了资料,发币者要想获取代币,需要调用 issue action 来获得代币。 void issue( account_name to, / 代币的发行方为账户为wangdenghui,之前已经创建 / asset quantity, / 发行代币的数量为10000个,代币名称为CBT / string memo ); / 表示备注说明,不能超过256个字节 /

执行输入结果如下:

duncanwang@duncanwang:~/eos$ cleos push action eosio.token issue '[ "wangdenghui", "10000.0000 CBT", "first ColorBayToken issue" ]' -p eosio
executed transaction: 33b23322d6a413108350a21f23c77150d77de71a8aeeaefd5befd9e30ceec288  144 bytes  2602 us
##   eosio.token <= eosio.token::issue           {"to":"wangdenghui","quantity":"10000.0000 CBT","memo":"first ColorBayToken issue"}
##   eosio.token <= eosio.token::transfer        {"from":"eosio","to":"wangdenghui","quantity":"10000.0000 CBT","memo":"first ColorBayToken issue"}
##         eosio <= eosio.token::transfer        {"from":"eosio","to":"wangdenghui","quantity":"10000.0000 CBT","memo":"first ColorBayToken issue"}
##   wangdenghui <= eosio.token::transfer        {"from":"eosio","to":"wangdenghui","quantity":"10000.0000 CBT","memo":"first ColorBayToken issue"}
warning: transaction executed locally, but may not be confirmed by the network yet        

2.5 代币转账

辉哥账号转账给欧阳哥哥合计8000个彩贝币,用于支付午餐费用。

cleos push action eosio.token transfer '[ "wangdenghui", "ouyanggege", "8000.0000 CBT", "pay for lunch!" ]' -p wangdenghui

转账成功输出结果:

duncanwang@duncanwang:~/eos$ cleos push action eosio.token transfer '[ "wangdenghui", "ouyanggege", "8000.0000 CBT", "pay for lunch!" ]' -p wangdenghui
executed transaction: 42c0f99566561977424df6417581114c3d9865c5194256f6b7a1311abf97802a  144 bytes  2011 us
##   eosio.token <= eosio.token::transfer        {"from":"wangdenghui","to":"ouyanggege","quantity":"8000.0000 CBT","memo":"pay for lunch!"}
##   wangdenghui <= eosio.token::transfer        {"from":"wangdenghui","to":"ouyanggege","quantity":"8000.0000 CBT","memo":"pay for lunch!"}
##    ouyanggege <= eosio.token::transfer        {"from":"wangdenghui","to":"ouyanggege","quantity":"8000.0000 CBT","memo":"pay for lunch!"}
warning: transaction executed locally, but may not be confirmed by the network yet

2.6 查询余额

查询辉哥和欧阳哥哥的账号,核实金额是否已到账。

cleos get currency balance eosio.token wangdenghui cleos get currency balance eosio.token ouyanggege

正确输出结果:

duncanwang@duncanwang:~/eos$ cleos get currency balance eosio.token wangdenghui
2000.0000 CBT
duncanwang@duncanwang:~/eos$ cleos get currency balance eosio.token ouyanggege
8000.0000 CBT

2.7 阅读eosio.token智能合约代码

EOS 官方提供了一个代币(资产)智能合约 Demo —— eosio.token,这个示例合约给出了 EOS 官方智能合约开发的标准结构和开发方法,并且真正的 EOS 代币也会借鉴这个示例合约的逻辑,是 EOS 智能合约入门的经典案例。 默认情况下,该智能合约存在路径:~/eos/contracts/eosio.token 文件解释如下: eosio.token.hpp - 头文件,定义类和函数 eosio.token.cpp - 实现 eosio.token.abi - Application Binary Interface,是一个接口文件,描述了智能合约与上层应用之间的数据交换格式 CMakeLists.txt - 编译文件
