中文 (Chinese) / BTS2.0升级/注册/交易指南
« on: December 25, 2015, 01:04:55 pm »
本帖意在为在BTS平台交易时遇到困难的小伙伴们提供一个一贴式的教程,仅仅是不知该如何交易的小伙伴请直接移步第三部分,还没有注册BTS钱包的小伙伴请移步第二部分;还需要升级1.0钱包的小伙伴请从头开始读。

一、 BTS1.0升级至BTS2.0
这里需要首先将Bitshares客户端升级至0.9.3C版本,然后导出一个json格式的秘钥文件,再之后导入到BTS2.0.

下载0.9.3c安装文件:http://www.bts.hk/downloads.html
卸载以前版本的BitShares客户端,然后安装新版本。

以下两步可能是可选的:
1.尝试与blockchain同步(如果你认为你上一次同步之后,你的帐户还有新的交易)
2.把所有的资金发送给自己(这一步也是可选的,如果你跳过此步骤,导入至2.0也没有问题)

使用控制台导出钱包文件
帐号列表 - >高级设置 - >控制台
输入:wallet_export_keys D:/keys.json,亦可选择其它路径和文件名。
然后按回车执行。


注意:导出的钱包文件将用你的密码进行加密!请务必再次尝试使用该文件时要记住它!
注意:如果你使用的是Windows,你的文件路径尝试直接访问C驱动器(例如C:keys.json),你可能需要管理员权限运行BitShares客户端。所以最简单的做法就是模仿上面的例子。

然后移步网页钱包 https://bitshares.dacplay.org/ 点击右上齿轮,进入钱包管理控制台界面:


选择上面导出的秘钥文件,确定导入。搞定。

二、注册BTS2.0钱包

点击巨蟹DACPLAY网页钱包的专属推荐链接:https://bitshares.dacplay.org/?r=bitcrab

输入密码后点“创建新钱包”


然后创建新账户,就好了。

三、交易

BTS2.0里面现在可以交易的资产大致有这么几种:一是BTS和智能货币,其中智能货币又包括系统发行的和私人发行的。二是交易所/承兑商在平台发行的用户定义资产。用户定义资产是需要发行人来背书的。

目前已有多家交易所/承兑商在BTS平台发行用户定义资产。用户可以直接通过钱包里的链接完成这些资产的充值和提现。

下图是钱包中metaexchange的充值提现界面。


在BTS去中心化交易所DEX中,任何两种资产都可以组成交易对。下面就以ANTSHARE/TCNY交易对为例,描述一下如何交易。

小蚁股是transwiser在BTS平台发行的UIA,对应小蚁项目中的小蚁股,目前的发行根据种子期投资人与巨蟹签订的服务合同进行。在小蚁股上线后将可以正常提现。决定交易前请仔细阅读https://bitsharestalk.org/index.php/topic,20650.0.html

TCNY是transwiser在BTS平台发行的智能货币,多人管理,与BITCNY主要的不同是强制清算补偿为2%。可以很好地与人民币锚定。详见https://bitsharestalk.org/index.php/topic,20626.0.html

目前TCNY的充值是通过淘宝店进行的,如果你有意购买BTS平台中的ANTSHARE,你可以通过下图中的链接(https://item.taobao.com/item.htm?spm=a1z10.1-c.w4004-9480054247.2.qZQL8X&id=525288636460)到淘宝店购买TCNY充到你的BTS钱包,注意要在用户留言中填写你的BTS账户号并及时确认收货哦。



充好TCNY后在交易->更多交易对总搜索ANTSHARE:TCNY交易对:



然后就可以交易了:

中文 (Chinese) / 引入部分小蚁股在BTS平台交易的计划
« on: December 15, 2015, 04:00:38 pm »
小蚁大致会在3-5个月内还要进行一次人民币众筹,然后如果顺利的话可能会在2-3个月内上线。

transwiser计划在小蚁正式上线之后成为完全意义上的小蚁股(可能还有小蚁币)BTS网关,在BTS平台提供小蚁股和小蚁币的充币提币服务。为小蚁股用户到BTS平台交易创造安全方便快捷的条件。

在这之前,transwiser计划部分地引入小蚁股到BTS提前交易,之所以说是部分的,是因为:

1.本着风险可控的原则,此次只接受除小蚁团队成员之外的小蚁种子轮投资人(注:这里种子轮投资人指2014年6月共同出资100万元人民币启动小蚁项目的一家投资机构和9位自然人)手中的小蚁股权益到BTS平台交易,有交易意向的种子轮投资人将通过合同转让的方式将手中的小蚁股转让给我(巨蟹/刘嘉陵),以换取transwiser在BTS平台发行的ANTSHARE资产。

2.在小蚁正式上线之前,BTS平台上的ANTSHARE资产只能交易,无法提现。

transwiser能够保证的是:

如果小蚁股最终完成开发,正式上线,那么transwiser发行的每一份ANTSHARE资产都将能提现出等量的小蚁股。

transwiser提请用户注意的风险有:

1.小蚁的开发还有诸多的不确定因素,最终的上线时间有可能跟预期时间存在较大差别。
2.如果小蚁项目因政策、技术、市场等原因最终未能推出产品,而小蚁团队转向从事其他区块链协议开发,小蚁团队将在新的区块链协议中为投资人保留同等金额的权益份额。此种情况下,transwiser只保证每一份ANTSHARE资产都能换取小蚁团队为投资人保留的同等金额的新区块链协议权益份额。
3.BTS平台目前还不是一个用户众多的平台,加上此次最终参与交易的小蚁股只占小蚁股总量的一小部分,市场价格可能会有较大起伏并与“合理价格”有较大偏离。

请仔细判别风险,谨慎投资。

关于小蚁股的情况,请访问https://www.antshares.com/, 或加入小蚁社区QQ群23917224.
小蚁股的分配方案及过往估值情况见http://weibo.com/p/1001603897969156959456

还没有BTS钱包的小伙伴可以戳https://bitshares.dacplay.org/?r=bitcrab注册BTS钱包。
transwiser将主要培育TCNY/ANTSHARE交易对,TCNY可由BTS抵押产生,或者到transwiser淘宝店购买https://item.taobao.com/item.htm?spm=686.1000925.0.0.7LqY2u&id=525288636460

中文 (Chinese) / 为什么你应该选择TCNY而不是BitCNY
« on: December 14, 2015, 03:37:32 am »
BitCNY和TCNY都是BTS2.0平台上的智能货币,它们在设计上的结构是相同的,都是通过抵押BTS创造出来的与CNY锚定的金融衍生品,但前者是公共产品,后者是私人产品。

在设计上,TCNY和BitCNY有以下几点不同:

1.BitCNY的发行人是committee-account,由BTS理事会掌管,理事会通过投票的方式在需要的时候对BitCNY的参数进行调整;TCNY的发行人是transwiser-mpaadmin(目前是bitcrab,不久后将转给transwiser-mpaadmin),由一个TCNY的理事会掌管,同样TCNY理事会在需要的时候也会通过投票的方式对TCNY的参数进行调整。

2.无论是BitCNY还是TCNY,持有者都可以发起强制清算(force settlement),清算延迟时间都是24小时,最大每日清算量都是供应量的2%,但TCNY执行强制清算时,清算发起者将向被清算的空头仓位持有者提供2%的价格补贴。而BitCNY这个补贴为0.

3.BitCNY的MSSR(轧空比率)参数为110%,TCNY为100.1%,这意味着,对于爆仓价(Your Call Price)同样为A的空头仓位来说,TCNY仓位当喂价跌到A的时候会爆仓,而BitCNY仓位当喂价跌到1.1A的时候就会爆仓。/*升级至1223后此项已无必要。

4.BitCNY喂价有效期为24小时。TCNY的喂价有效期为6小时。

以上几点设计上的改动,都是为了降低空头的风险,从而消除TCNY相对于法币CNY的溢价,使得承兑商有机会通过提供流动性实现TCNY与CNY的1:1锚定,增强其对商户的吸引力。

目前TCNY还未完全走上正轨,尚待完成的任务有:争取到至少7个喂价提供者;待permission页面bug修复生效后完成理事会权限设定;将TCNY加到钱包中的充值/提现页面,这些基本都是时间问题。

曾有朋友问我,如果你的TCNY将来运行的很好,然后BitCNY把你的参数抄去了怎么办?我觉得这个没什么好担心的,smartcoin是需要运营者的,运营者不但应该有机会获得收益,更重要的是需要对smartcoin的各项设计参数有一定程度的掌控,不然没有办法去把一个smartcoin运营好,而BitCNY最大的问题恰恰在于它是一个公共产品,它掌握在BTS理事会这样一个行动受到各种牵制,且并不以“把BitCNY运营好,价值最大化”为第一使命的机构手里,你无法指望它去搞出来一个最优化的BitCNY出来,我相信将来一定是私人的智能货币产品战胜公共产品。

另外需要说明一点的是,transwiser将继续对BitCNY提供承兑服务,但不再按1:1的价格出售BitCNY,价格将根据当时对市场和风险的判断确定,基本上都会有少许溢价,对于BitCNY流动性的保障也将适可而止。

Stakeholder Proposals / Witnesses, could you please feed price for TCNY?
« on: December 13, 2015, 04:39:37 am »
TCNY is the first privatized smartcoin in BTS, its parameters are  as same as BitCNY except:

1. feed_lifetime_sec will be 7200
2. force_settlement_offset_percent will be 2%

TCNY accept witnesses to provide feeds. if possible please provide feeds to TCNY with MSSR as 100.1% instead of 110%.
we now have 3 witnesses delegate-clayop, delegate.baozi, and in.abit to provide feeds, hope more witnesses join!

Thanks for helping TCNY to grow up!

« on: December 09, 2015, 03:50:03 pm »
the private smartcoin TCNY is created and below is the info of it.
the issuer is bitcrab, later it will be transfered to a multisig account.
for price feed script, I hope the default SQP value can be set to 100.1% instead of 110%. other setting can be set as same as BitCNY.
@xeroc can you modify the script if necessary?

General Discussion / Plan to run private smartcoin TCNY
« on: December 07, 2015, 01:03:21 pm »
transwiser plan to create and run a private smartcoin TCNY.

at first, the parameter of TCNY will be as same as BitCNY except:

1. feed_lifetime_sec will be 7200
2. force_settlement_offset_percent will be 2%

the first change is to make the feed price to trace actual market price more closely. the second change is to make 1:1 pegging possible and attract merchants/customers.

we will have a TCNY committee, which will control the parameter of TCNY by votes, at first there will be 4 memeber, below are their accounts and weights:

1. bitcrab 3
2. baozi(alt) 1.5
3. gulu 1
4. harvey 1

the committee's task is to manage the parameter of TCNY in a decentralized manner, prevent TCNY from being hurt by one single dictator, in the future we will invite more member to join the TCNY committee if necessary.

transwiser will provide gateway and market maker service for TCNY.

we will try to make TCNY an attractive smartcoin for traders, merchants/customers and speculators. hope we can get support from community, witnesses and developers.

中文 (Chinese) / transwiser发行私人智能货币的计划
« on: December 03, 2015, 03:04:06 pm »
这几天发生的事情,让我对“我为什么要辛辛苦苦地培育BitCNY的市场”这个问题开始了深深的思索。

强清功能出现在轻钱包的时候,系统并未做好准备,不但CNY喂价依然明显偏低,强清的参数之一“最大清算量”的设计值2% 也被错设成了20%,这两者都极大地增加了shorter的风险,而且这风险是本不该有的,在费了九牛二虎之力终于把这两个危险因素消除之后,总算可以松一口气。

现在的BitCNY,虽然强清给shorter带来的风险已被降至最低,但还是有一个让人蛋疼的地方,就是强清的后果之一是给BitCNY带来了溢价,换句话说如果你有空仓,你就完全不乐意以1:1的价格出售BitCNY,因为这意味着你在给有可能向你发起强清的人提供子弹。

那么也就是说transwiser的1:1承兑的模式在现在的BitCNY这里已经进行不下去了。

其实还可以继续改,BitCNY有一个"force_settlement_offset_percent“的参数,是设定强清时发起强清一方向shorter的补偿的,如果设定一个合适的值(2%~5%?)那么是可以消除掉BitCNY的溢价的,重新使承兑成为可能的。

但我已经没兴趣为此再去理事会战斗了,因为我发现了解决问题的更好的方式,那就是-发行私人智能货币。

BTS2.0里新增了发行私人智能货币的功能,也就是说,任何用户都可以创造一种类似BitCNY这样的资产,比如叫TCNY,设定各种参数,然后其它用户可以象发行BitCNY一样抵押BTS来发行TCNY。

那么,我可以根据我对市场的理解来设定各种参数,做出来一个比BitCNY更符合市场需要的货币。

提供网关服务,引入各种交易品种到BTS中和TCNY交易。

而且TCNY的创造者还可以定义费率,收取费用。

所以啊,BM给给你提供了搞私人智能货币得可能,你还在那里苦逼地搞BitCNY不是傻逼吗?

要搞就搞得像模像样点,第一步,先拉几个人一起成立一个理事会,货币参数的改动必须由理事会成员以类似N/M签名的方式决定。

然后是确定发行的各种参数,这个且听下回分解。。。

Technical Support / poll for disabling force settlement for BitCNY.
« on: November 30, 2015, 02:22:33 am »
the force settlement feature may, in high probability, bring big chaos to the well organized BitCNY ecosystem.
we now suggest to disable the force settlement feature for BitCNY,  meanwhile leave it active for other bitAssets,  it is technologically possible.
if you are a member of the BitCNY ecosystem, please vote to let us know your opinion.

208
 
  Why a shorter short?
   
  obviously because he judge that something is overvalued.
   
 in BTS term shorter refer to the users who judge that fiat is overvalued, on the contrary, BTS is undervalued, so they short BitAssets, they hope when the BTS price rise up they can sell their BTS to get BitAssets back to cover the short position, and then make profits.
   
 shorters bear the risk of being margin called.
   
 so the basic logic for shorters is that he can hold his collateral when the collateral ratio is sufficient and wait for the price change.
   
 now you make the force settlement, which means anyone can get the collateral from the shorters at the feed price, no matter how high his collateral ratio is.
   
 isn't it robbery? when BTS price is low, speculators can get BTS by force settlement as they will, they can even supress the BTS price in external exchange to lower the feed price to make them even better conditon to rob BTS from shorters.

   trade logic should be, you can ask to buy, but I can refuse to sell, even the leverage contract only get settled in some special conditons, now you enable any one can force settle any time. why be so cruel to shorters?

   you said force settlement is not new, it comes out for long time. anyway, in 1.0 there is no such force settlement, but many shorters's positions are inherited from 1.0, shouldn't you be more cautious when it's possible to hurt a group of users?

now let's check what force settlement will bring to the market.

in BitUSD market the BTS price is always lower than feed price, we can forsee that seldom force settlement will happen.

in BitCNY market as now force settlement is well known, BitCNY will be priced more expensive than CNY, suppose 1.05 CNY, transwiser paused the deposit business, and no one will use BitCNY to deposit to BTC38.

for pegged asset it's important to peg well, just get a price floor will make no sense, if 1 BitCNY always worth 1.05 CNY, no merchant would like to use it, they won't list 2 different prices for one single goods, one for CNY, the other differnent for BitCNY. and if the merchant just regard BitCNY as same as CNY,  who want to pay in BitCNY?

force settlement will bring chaos to the well organized BitCNY ecosystem, and do good only to speculators.

let me repeat my suggestion: please make force settlement an asset-specific feature, and committee can decide to which asset the feature will apply, then for example we can enable this feature for BitUSD and disable it for BitCNY,  by doing so we can also compare the behavior of these 2 MPAs to analyse what force settlement bring to the market and decide further.

209
in the new versionn 151125, a "SETTLE" button appear under the balance tab, as stated in the help, "Holders of any bitAsset can request a settlement at a fair price at any time. The settlement closes the borrow/short positions with lowest collateral ratio and sells the collateral for the settlement."

alt told me some more detail, "if anyone request settlement with asset A, one day later he can buy BTS from the asset shorter with the lowest collateral ratio with the latest settlement price. "

I am surprised to hear this, as a big BitCNY shorter, it seems this feature put me in danger.

Why we need this feature?

yes, maybe it can really raise the collateral ratio as a whole, because each shorter will run away from the lowest collateral ratio space. but does this really do good to the whole ecosystem, MPA supply will be lowered and more BTS will be unlocked for exchange.

shorters are always in danger, they always face the danger of margin call, this feature provide each user an opportunity to rob them.

and is this kind of rule reasonable? when one put his assets into collateral, anyone  can buy these collateral with a so called "fair price", not because the collateral ratio meet the maintenance ratio, but because the collateral ratio is the lowest!

and currently the settlement fed by witness is often not the fair price. say the feed price for BitCNY/BTS is 0.0205, but are there anyone can sell me BTS at 0.0205 CNY? if yes, please let me know.

as a shorter I have been hurt by the unexpected rule change at 16th,OCT, now I worry whether I will be hurt once more.

please stop robbing the shorter.

中文 (Chinese) / 与收费狂魔战斗,你可以贡献你的力量!
« on: November 26, 2015, 03:00:37 pm »
标题仅供娱乐,请勿当真。 8)

社区对于降低仓位调整费没什么反对的声音,应该几天后会顺利实施:https://bitsharestalk.org/index.php/topic,20265.0.html

我想降低这个收费,是因为我觉得供应MPA的人是在给社区做贡献,然后还要忍受这么高的费用是一件很让人蛋疼的事情。

如果你很想调整某些收费,请跟帖说明并写出你的理由,如果我觉得要求很合理也很实际,我会考虑提建议调整。
现在的收费结构见这里:http://cryptofresh.com/fees

一个最终能够顺利设施的费用调整建议通常要满足下面条件:
1.理由很明确,并且(至少看起来)对社区的作用是正向的。
2.照顾各方利益,能够最终达成妥协,不会引起社区分裂。
