DAC 委托人 / delegate，这里有自动喂价程序（BitSuperLab 出品）
« on: August 25, 2014, 03:16:36 pm »
https://github.com/Bitsuperlab/operation_tools/tree/master/btsxfeed

本来以为手动喂价就够了，看来没这么简单，最好还是自动喂价，让启动价格和交易所不要相差太远。
复制 config.json.sample 为 config.json，修改其中相关配置，主要是rpc端口、密码，delegate名称。
比如要对 CNY，USD喂价，运行命令：
Code: [Select]
  ./btsx_feed_auto.py  CNY USD
如果不带参数运行，不会发布喂价，只实时显示价格。

中文 (Chinese) / delegate要注意啊，设置 feed price 一定要谨慎
« on: August 20, 2014, 05:34:54 am »
今晚11：30可能要硬分叉，启动交易功能
对每一个市场需要有50个delegate输入 feed price才能启动，注意市场一旦启动之后，价格限制就再不受delegate控制，而是使用的一小时均价。
因此大家输入 feed price一定要谨慎，别搞错了，比如美元市场现在大概价格是 0.011USD/XTS，设置命令如下，delegate帐号名要改成自己的。
Code: [Select]
wallet_publish_price_feed delegate.baozi 0.011 USD

另外为保证系统安全，建议前期只开启美元市场，待运行稳定之后，其它市场我们要一个一个开启，避免同时开启后深度不够容易被人为操控。
所以其它市场的 price feed 大家现在千万不要设置，待达成共识之后统一行动。

You can send them a small amount, like 0.1 btsx and put a message in it.

I did. Sent him/her a transaction/message asking for btsx back...

I feel so dumb and disgusted right now..  >:(  :'( :-\

Follow My Vote / let it be beneficial to vote for the right one
« on: August 18, 2014, 03:38:26 am »
I think the lotto reward can be using at  BTS-vote too,
give some reward to the one who vote for the winner
let it be beneficial to vote for the right one.
Quote from: alt on August 17, 2014, 11:55:20 pm
I have an idea to encourage users to vote, for 101 delegate.
like LOTTO, for example, we have 101 delegate active now, they have get their votes, maybe totally 40,000,000,000 votes.
we generate a random number between 1-40,000,000,000 every 24*60*6 blocks.
we can get this lucky vote's address
then give a lucky reward  to this address, part of  the destroy fee at this day.

to increase the chance to get the reward, users need to vote more delegate, and to the right delegate.

中文 (Chinese) / dry run 15 的攻击方法
« on: August 15, 2014, 06:49:18 am »
今晚还有事情，不想测试了，把方法写出来，有空的去试试吧。

方法一：这个攻击的思路是操控均价到很低，让short暴仓，利用暴仓后会凭空生成bts买单的规则，大量吃进廉价bts。注意暴仓后的cover价限制在均价的2/3以上了，所以必须要把均价拉低才能成功。

1.按最低价下 200万XTS short，托底，保持市场深度要求。
2. 买入 bitusd ，砸穿所有正常价位的  bid/short 买单，让剩余 bid/short最高价在 1/100 以下。挂一个不能成交的1/100价位以下的 ask。每多保持1分钟，均价就能跌1/60。
3. 可以考虑撤销最开始的托底单，深度不够，交易停止，这样能帮助均价保持下跌。
4. 如果有人要阻止攻击，增加了深度，且挂了高价bid，那就按1/100挂 ask 单砸。注意坚持一会就会有大量暴仓的 xts 出来帮助你一起砸。此时系统刚启动，没有那么多bitusd跟你打。
但对方如果直接挂了1千万的 short，就要看你的实力了。。。。
5. 等均价跌到1/100, 按此价挂 bid/short 单，吃掉所有暴仓的便宜 xts。

这种攻击有点难度，要有足够的xts压价。最好在人少的时候偷偷干。以上1/100换成1/10000同样有效。

方法二：short 价位限制在低于均价的4/3了，同样需要控制均价，把价位拉高。然后按很高的价格 short bitusd，自己再吃进。能获取大量bitusd。
这个攻击相对上面的简单很多了，砸穿后马上挂一个一万倍的单子，平均下来也能把价位拉高 10000/360 倍。挂一个1亿倍的呢？
可惜现在 ask 有 1300 万 xts 深度，大概需要 1500万XTS的攻击成本。

中文 (Chinese) / 从这个角度看1股多投你们能理解吗？
« on: August 05, 2014, 07:52:03 am »
有人说投票就该1股1票投，人家公司都这么干的。
那好啊，股东大会是1人1票，那至少要50%通过才算有效吧？没有哪个是1%就能代表公司利益，就能通过决策的吧？

如果非要纠结1票1投，从下面这个角度你们能接受吗？
现在开会了，投票选代表。
首先请参选者排队
现在是1号选手BM，大家同意吗？同意的投票，每股1票。。。。   
现在是2号选手烤面包，大家同意吗？每股1票。。。。。
现在是3号选手黑鱼人，大家同意吗？每股1票。。。。。。

最后，得票最高的前101位代表当选
请问这还是算1股1票吧？就算有1000个备选代表，每股能投1000数票我也没看出来有什么问题

在DAC系统中，没法按上面提到的那样举办股东大会，等大家一个个投票。
因此以现在这样1个人投101票的形式出现了，但其本质上是相同的。
请反对者说说，上面那个投票流程有什么问题？

here is another solution for hot standby, detected with a heartbeat signal.

master and slave exchange  some data in real time, include: blockchain_head_block_num, network_num_connections.
they'll change block production flag automatic, depend on  a rule to select which one should active.

we use a pusher service from PubNub to exchange data, this can avoid open a public service, and can still run behind a tor net.

so you need to register a free account in PubNub if you decide to use this. the demo account maybe not stable.
here is the command
这种方案比较复杂一点，做了心跳检测，比较双方的状态数据，根据规则选择一台生产。
