MyModule
自己实现的简单应用的业务逻辑。

实现了很简单的逻辑,这个模块接收两种消息MsgDoMsgUndo,前者消息的操作是根据提供的非负整数N,对发送消息的账户,增加10steak*N的token,后者则是撤销由MsgDo消息导致账户累计增加的全部token。具体细节可以见Usage.

编译安装,生成gaiad与gaiacli。

gaiad init gen-tx --name=gov1 --home="gaia1"
{
"app_message": {
"secret": "siege brief foam drive side oak strong swear evoke clutch business uphold giraffe lava assume abandon"
},
"gen_tx_file": {
"node_id": "7d8e637b63a16099b36a75b0afe5a31a5a3515df",

},
"power": 100,

},
"app_gen_tx": {
"name": "gov1",

"pub_key": {

}
}
gaiad init --gen-txs --chain-id=gov-test -o --home=gaia1
{
"chain_id": "gov-test",
"node_id": "7d8e637b63a16099b36a75b0afe5a31a5a3515df",

}
构建与初始化测试网
gaiacli keys list
NAME: ADDRESS: PUBKEY:
gov1 D2A7EAFFAC63040166C1FB669D2B32CEC40240EB 1624DE62203EB89AB4E005EC3DCF348466895583713CB2EFEC452A42D4C0F9697DAE3B824C
查询当前测试网的账户,其实这个账户就是创建节点的初始用户,他的地址就是D2A7EAFFAC63040166C1FB669D2B32CEC40240EB,默认有50个steak.
gaiad start --home=gaia1
启动节点gov1
VADDR1=D2A7EAFFAC63040166C1FB669D2B32CEC40240EB
设置账户的环境变量,后面的命令可以很方便的使用。
gaiacli do $VADDR1 5 --name=gov1 --chain-id=gov-test
gaiacli account $VADDR1
{
"type": "6C54F73C9F2E08",
"value": {
"address": "D2A7EAFFAC63040166C1FB669D2B32CEC40240EB",
"coins": [
{
"denom": "gov1Token",
"amount": 1000
},
{
"denom": "steak",
"amount": 100
}
],
"public_key": {
"type": "AC26791624DE60",
"value": "PriatOAF7D3PNIRmiVWDcTyy7+xFKkLUwPlpfa47gkw="
},
"sequence": 1
}
}
发送MsgDo消息 查询账户余额为70steak,因为50steak+5*10steak,一共是100steak
gaiacli account $VADDR1
{
"type": "6C54F73C9F2E08",
"value": {
"address": "D2A7EAFFAC63040166C1FB669D2B32CEC40240EB",
"coins": [
{
"denom": "gov1Token",
"amount": 1000
},
{
"denom": "steak",
"amount": 150
}
],
"public_key": {
"type": "AC26791624DE60",
"value": "PriatOAF7D3PNIRmiVWDcTyy7+xFKkLUwPlpfa47gkw="
},
"sequence": 2
}
}
再次发送MsgDo消息 查询账户余额为150steak,因为100steak+5*10steak,一共是150steak
gaiacli undo $VADDR1 --name=gov1 --chain-id=gov-test
gaiacli account $VADDR1
{
"type": "6C54F73C9F2E08",
"value": {
"address": "D2A7EAFFAC63040166C1FB669D2B32CEC40240EB",
"coins": [
{
"denom": "gov1Token",
"amount": 1000
},
{
"denom": "steak",
"amount": 50
}
],
"public_key": {
"type": "AC26791624DE60",
"value": "PriatOAF7D3PNIRmiVWDcTyy7+xFKkLUwPlpfa47gkw="
},
"sequence": 2
}
}
发送MsgUndo消息 查询账户余额为50steak,因为150steak-50steak-50steak,最后剩50steak
