EOS最新进展跟踪 （track of latest updated EOS）---10/10/2017

跟踪EOS项目进度将是我把钱投过去之前的一个任务，最近根据这个说明创建了一个EOS区块链和一个智能合同转移资金。
To track the progress of EOS project is a top task for me before invest my money into it, I recently create an EOS blockchain and a smart contract over it to transfer EOS to an account following this instruction.
https://github.com/eosio/eos#singlenode

我是在ubundu系统下安装EOS的。
I installed EOS in ubundu system.

git clone https://github.com/eosio/eos --recursive

cd eos
./build.sh ubuntu

如果你这么做，会报错，说mode不正确，这时候需要这样做：
If you do it that way, it will complain incorrect mode, so the correct way should be：

./build.sh ubuntu full

按照指示一步步做下去，我的区块链就跑起来了：
Following the instruction step by step, the genesis block was created and my private blockchain was built up:

我觉得eos有个很大好处是用plugin可配置性，比如wallet。
I feel one of the benefits of EOS is its configurability, e.g. it can use plugin to set wallet.

为例子合同”currency” 创建账号。
Creating accounts for sample "currency" contract.

cd ~/eos/build/programs/eosc/
./eosc create key # owner_key
./eosc create key # active_key

这里，我开始很困惑，但是，你真的需要把create key运行两边，产生两组private key，public key.
I was quite puzzled in the first place, but, you did need to run ‘create key’ twice to generate two pairs of ‘private key’ and ‘public key’.

需要把刚才运行得到的两个public_key代入：
You should replace the ‘PUBLIC_KEY_1’ and ‘PUBLIC_KEY_2’ with public keys we generated in the previous step:

./eosc create account inita currency PUBLIC_KEY_1 PUBLIC_KEY_2

“Messages are not sent "from" anyone, they are sent "with permission of" one or more accounts and permission levels. The following commands shows a "transfer" message being sent to the "currency" contact.”
这对哥来说是个新的概念，把原先从一个账号发送钱到另外一个账号的概念取消了，变成从一个合同发钱到另外一个账号了。
合同本身就可以发钱和收钱，不需要额外发送账号。
This is a new concept for me, there is no ‘from’ account, you just sent money with permission of an account or a group of accounts.

EOS有个让我很头晕的地方，就是账号和key，我觉得很多是多余的。

One thing always confuses me is the account and key, I feel some of them are redundant;

创建钱包时候，系统自动创建了private key；
在config.ini里有个现成的inita的账户，用wallet import private key来获取它，以获取创建’currency’账号的权限；
owner_key and active_key：每个key都带一对private_key/public_key, 这个概念我在steemit里看到过；
用inita的权限创建出来的’currency’账号跟后来的’currency contract’是什么关系？没有说明。从后来资金转移后各账号看：inita currency 余额50，而currency account 的余额999999950来看，’currency’账号是inita下面的一个账号，跟’currency contract‘没有关系，这个让我很困惑，因为inita账号里以开始就有1000000 EOS的。

When you created a wallet, the system automatically create private key for you, this is for the wallet itself;
There is an existing account in config.ini called ‘inita’, we must use private key to import it so that we can obtain the permission to create subsequent ‘currency’ account;
I cannot understand ‘owner_key’ and ‘active_key’ which I saw in Steemit, each of them has a pair of private key/public key;
What is the relationship between the ‘currency’ account created by the permission of inita and the ‘currency contract’? it is not stated here. I can only infer the possible relationship from the token transfer result: the balance of inita currency is 50 after transferring, while the balance of ‘currency’ account is 999999950, there is no link between ‘currency contract’ and ‘currency account’, this confused me so much since I can see there was existing 1000000 eos in the inita account.

希望Daniel Larimer这个Byte Master不要因为自己的任性而搞砸了EOS，要知道，很可能有成千上万的投资者翘首以盼呢。

Hopefully, Daniel Larimer won’t screw up the EOS project due to his wilfulness, as you know, thousands of investor are waiting for good news from EOS.
