Init with creating accounts and assigning balance

[pchain-org]

参考 https://github.com/pchain-org/pchain/blob/master/!!restore!!/readme.txt，

在步骤3.1中，

#package the genesis.json and init chain data
ethermint -datadir /home/ubuntu/.ethermint init ./src/github.com/tendermint/ethermint/dev/genesis.json

#create default user
cp -r ./src/github.com/tendermint/ethermint/dev/keystore /home/ubuntu/.ethermint/keystore

分别生成了tendermint和ethereum中账号。

需要改为通过上述的 init 命令，就能完成上述的两个动作： 1，在 datadir 目录下生成 genesis.json文件和keystore目录，内容为是同一个ethereum账号的密钥和余额 2，可以生成priv_validator.json文件，这样现有对priv_validator.json进行访问的代码可以不做改动。但是私钥的明文就暴露了。 也可以不生成priv_validator.json，这样需要改动现有访问priv_validator.json的代码，改成直接从keystore中读取。

[pchain-org]

对上述的需求加以进一步描述：

• 增加一个 init_eth_genesis 命令，调用方式为:

ethermint --datadir /home/ubuntu/.ethermint init_eth_genesis "10000000000000000000000000000000000, 10000000000000000000000000000000000, 10000000000000000000000000000000000, 10000000000000000000000000000000000, 10000000000000000000000000000000000"

字符串内为每个账号的初始化的balance，以 ‘,’ 隔开

执行后结果为： 1，在 --datadir 目录下，产生keystore文件夹，里面存放和账户个数对应的若干个私钥文件；该文件夹和ethereum兼容 2，产生和账户个数对应的若干个priv_validator.json文件；内容应该和keystore里面的内容保持一致，保存为json文件是为了和tendermint兼容 3，生成/home/ubuntu/.ethermint/eth_genesis.json。只是里面的账号和余额变成如下形式： "alloc": {

"0x7eff122b94897ea5b0e2a9abf47b86337fafebdc": {

"balance": "10000000000000000000000000000000000"

}，

"0x1234122b94897ea5b0e2a9abf47b86337fafebdc": {

"balance": "20000000000000000000000000000000000"

}，

"0x5678122b94897ea5b0e2a9abf47b86337fafebdc": {

"balance": "30000000000000000000000000000000000"

}， ... }

• 增加上述命令后，初始化过程为：

1, ethermint --datadir /home/ubuntu/.ethermint init_eth_genesis "10000000000000000000000000000000000, 10000000000000000000000000000000000, 10000000000000000000000000000000000, 10000000000000000000000000000000000, 10000000000000000000000000000000000"

2，ethermint -datadir /home/ubuntu/.ethermint init /home/ubuntu/.ethermint/eth_genesis.json

执行上述两个命令后，应该产生如下结果： 1，产生类似下面的genesis.json文件 { "app_hash": "", "chain_id": "test-chain-IsbFzq", "consensus": "pos", "current_epoch": { "block_generated": "0", "end_block": "1295999", "end_time": "0", "number": "0", "reward_per_block": "368267746913580247", "start_block": "0", "start_time": "0", "status": "0", "validators": [ { "amount": 10, "eth_account": "7EFF122B94897EA5B0E2A9ABF47B86337FAFEBDC", "name": "", "pub_key": [ 3, "046E5ACDC1CF2C6C61CF6528A0A33DF44ADEBCED18C0CDA4AF88A76B14DA33BD014B97E33A277685EA1787776364E4CE3A83593B5FC231D3EB69F5514E387680A7" ] } ] }, "genesis_time": "0001-01-01T00:00:00.000Z", "reward_scheme": { "added_per_year": "0", "allocated": "0", "descend_per_year": "572730000000000000000000", "pre_allocated": "178500000000000000000000000", "reward_first_year": "5727300000000000000000000", "total_reward": "210000000000000000000000000" } } 2，其他如config.toml等内容照常生成 3，调整genesis.json和config.toml文件，即可启动系统正常运行

[pchain-org]

增加描述。对于 init_eth_genesis 命令，调用方式调整为: ethermint --datadir /home/ubuntu/.ethermint init_eth_genesis "{10000000000000000000000000000000000, 100}， {10000000000000000000000000000000000, 100}，{ 10000000000000000000000000000000000, 100}， {10000000000000000000000000000000000, 100}，{ 10000000000000000000000000000000000，100}"

每一组的前面一个是balance，后面一个是amount；相应的api是xxxBalance和xxxLockedBalance

[pchain-org]

上一楼的命令中有中文逗号，两条完整的命令为：

1，ethermint --datadir /home/ubuntu/.ethermint init_eth_genesis "{10000000000000000000000000000000000, 100}, {10000000000000000000000000000000000, 100}, { 10000000000000000000000000000000000, 100}, {10000000000000000000000000000000000, 100}, { 10000000000000000000000000000000000, 100}"

2，ethermint -datadir /home/ubuntu/.ethermint init /home/ubuntu/.ethermint/eth_genesis.json

执行完上一楼的两条命令后，理论上应该得到包含5个validator配置信息的genesis.json 比如：

{
  "reward_scheme": {
    "total_reward": "210000000000000000000000000",
    "reward_first_year": "5727300000000000000000000",

实际生成的genesis,json只含有一个validator的配置信息：

{
  "reward_scheme": {
    "total_reward": "210000000000000000000000000",
    "reward_first_year": "5727300000000000000000000",

  },

现脚本部署多节点的初始化步骤如下： （假设部署4个节点分别为n0, n1, n2, n3） 1，在n0上执行./bin/ethermint --datadir /mnt/vdb/pchain_test/.ethermint init_eth_genesis "{10000000000000000000000000000000000, 100}， {10000000000000000000000000000000000, 100}，{ 10000000000000000000000000000000000, 100}， {10000000000000000000000000000000000, 100}"得到eth_genesis.json，4个账号对应的priv_validator.json及私钥文件。 2，在n0上执行./bin/ethermint -datadir/mnt/vdb/pchain_test/.ethermint init /mnt/vdb/pchain_test/.ethermint/eth_genesis.json初始化ethermint并得到genesis.json文件。 3，将n0上的priv_validator.json及私钥文件分别复制到 n1, n2, n3，保证每个节点只含有一份priv_validator.json及其对应的私钥文件。 4，将n0上的genesis.json复制到余下节点，并分别将Coinbase改为该节点对应的账号。 5，在余下节点上分别执行./bin/ethermint -datadir/mnt/vdb/pchain_test/.ethermint init /mnt/vdb/pchain_test/.ethermint/eth_genesis.json初始化ethermint。

问题：执行步骤5之后，余下节点会再次生成4个priv_validator.json，其中一个与该节点下已有的账号一致，三个是新生成的账号。 期望结果：不要再生成新的priv_validator.json。
