出块奖励返回
简述
CITA 中存在两种经济模型:Quota
和 Charge
模型,默认经济模型 Quota
,没有余额概念。 在具有余额的 Charge
经济模型中,出块奖励默认返还给共识节点,但运营方可以通过设置 checkFeeBackPlatform
和 chainOwner
,将出块奖励返还给自己。
出块奖励 = quotaUsed * quotaPrice, 其中 quotaPrice
默认为 1000000,quotaUsed
在交易回执中可以获取。
0.20 版本之前的默认
quotaPrice
是 1
操作示例
首先配置链的时候要注意三点:
- 配置经济模型
- 设置奖励返回开关
- 设置运营方地址
$ ./env.sh ./scripts/create_cita_config.py create \
--super_admin "0x4b5ae4567ad5d9fb92bc9afd6a657e6fa13a2523" \
--nodes "127.0.0.1:4000,127.0.0.1:4001,127.0.0.1:4002,127.0.0.1:4003" \
--contract_arguments "SysConfig.checkFeeBackPlatform=true" \
--contract_arguments "SysConfig.chainOwner=0x36a60d575b0dee0423abb6a57dbc6ca60bf47545" \
--contract_arguments "SysConfig.economicalModel=1"
接下来的测试,用 cita-cli 交互模式进行演示。
查看管理员和运营方地址余额
$ rpc getBalance --address "0x4b5ae4567ad5d9fb92bc9afd6a657e6fa13a2523"
管理员余额输出:
{
"id": 1,
"jsonrpc": "2.0",
"result": "0xffffffffffffffffffffffffff"
}
$ rpc getBalance --address "0x36a60d575b0dee0423abb6a57dbc6ca60bf47545"
运营方余额输出:
{
"id": 1,
"jsonrpc": "2.0",
"result": "0x0"
}
让我们来发一笔交易并获取回执,来看看余额的变化吧。
$ rpc sendRawTransaction \
--code "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" \

$ rpc getTransactionReceipt --hash "0x39c4cd332892fb5db11c250275b9a130bf3c087ebdf47b6504d65347ec349406"
回执输出:
{

"result": {

"transactionIndex": "0x0"
}
}
再来查一下余额:
$ rpc getBalance --address "0x4b5ae4567ad5d9fb92bc9afd6a657e6fa13a2523"
管理员余额输出:
{
"id": 1,
"jsonrpc": "2.0",
"result": "0xffffffffffffffffe7341af6ff"
}
$ rpc getBalance --address "0x36a60d575b0dee0423abb6a57dbc6ca60bf47545"
运营方余额输出:
{
"id": 1,
"jsonrpc": "2.0",
"result": "0x18cbe50900"
}
可以看到余额发生了变化,运营方的账户余额从 0 变成了 4e3b29200(十进制 106500000000 ), 查看交易回执中的 QuotaUsed 为 106500 (0x1a004)。
