| # Coin_Type的定义 | ||
| coin_type 定义了iris-hub系统中代币的可用单位，只要是系统中已注册的coin_type类型，都可以使用该单位来进行交易。iris-hub中系统默认的代币为iris，iris存在以下几种可用单位:iris-milli,iris-micro,iris-nano,iris-pico,iris-femto,iris-atto。他们之间存在以下换算关系 | ||
| ``` | ||
| 1 iris = 10^3 iris-milli | ||
| 1 iris = 10^6 iris-micro | ||
| 1 iris = 10^9 iris-nano | ||
| 1 iris = 10^12 iris-pico | ||
| 1 iris = 10^15 iris-femto | ||
| 1 iris = 10^18 iris-atto | ||
| ``` | ||
| coin_type的数据模型如下: | ||
| ```golang | ||
| type CoinType struct { | ||
| Name string `json:"name"` | ||
| MinUnit Unit `json:"min_unit"` | ||
| Units Units `json:"units"` | ||
| Origin Origin `json:"origin"` | ||
| Desc string `json:"desc"` | ||
| } | ||
| ``` | ||
| * Name : 代币名称，也是coin的主单位，例如iris | ||
| * MinUnit： coin_type的最小单位，系统中存在的代币都是以最小单位的形式存在，例如iris代币，在iris-hub中存储的单位是iris-atto。当用户发送交易到iris-hub中，使用的必须是该代币的最小单位。但是如果你使用的是iris-hub提供的命令行工具，你可以使用任何系统识别的单位，系统将自动转化为该代币对应的最小单位形式。比如如果你使用send命令转移1iris，命令行将在后端处理为10^18 iris-atto，使用交易hash查询到的交易详情，你也只会看到10^18 iris-atto。Unit结构定义如下: | ||
| ```golang | ||
| type Unit struct { | ||
| Denom string `json:"denom"` | ||
| Decimal int `json:"decimal"` | ||
| } | ||
| ``` | ||
| 其中Denom定义为该单位的名称，Decimal定义为该单位支持的最大精度，例如iris-atto支持的最大精度为18 | ||
| * Units：定义了coin_type下可用的一组单位 | ||
| * Origin：定义了该coin_type的来源，取值:Native(系统内部，iris),External(系统外部,例如eth等),UserIssued(用户自定义) | ||
| * Desc：对该代币coin_type的描述 | ||
|
|
||
| 如果想查询某种代币的coin_type配置，可以使用如下命令 | ||
| ```golang | ||
| iriscli coin types [coin_name] | ||
| ``` |
