@bitcrab I believe you are referring to this issue: https://github.com/bitshares/bitshares-ui/issues/202

It's on the first sprint to resolve.

thanks, my concern is not the compete between different wallets, but whether the community sanctioned development is on the right way, we need to try to avoid wasting resources.

I'll try to collect more info and then give my opinion soon.

I have one concern:

will this worker proposal plan to do something to optimize the performance of the UI?

I have discussed with some developers, I was told that there are some issues in the UI which caused low performance, for example, someone told that he found when one summit one operation in the GUI, about 20 requests will be sent to API server, some other designs, such as how the charts update, may also lower the performance.

some even conclude that without  redesign of the UI infrastructure it do not have a good furture. very limited clients with such UI can access an api server concurrently.

@alt even begin a project with meteor+mongodb+ddp protocol to build a service that can serve wallet to get high performance, mobile wallet - ICOWALLET will adopt this infrastructure.

I am not sure that I describe the issue exactly but I feel before we decide to upgrade the UI we need to consider this issue and decide whether and how to handle it.

中文 (Chinese) / 对BSIP18要干什么的解释
« on: July 14, 2017, 06:21:16 am »

https://github.com/bitshares/bsips/blob/master/bsip-0018.md

当市场急剧下跌,爆仓的smartcoin空仓无人接盘,继续下跌就会出现黑天鹅 - 当抵押率最低的空仓抵押率已经小于100%,已经资不抵债了,就是黑天鹅发生了,黑天鹅价格 = 抵押率最低的空仓的债务量/抵押物量。

以bitCNY为例来说明

假设bitCNY发生了黑天鹅,那么按照设计,系统会自动启动global settlement,就是系统用黑天鹅价格向所有空仓提供bitCNY以帮助其平仓,同时系统获得相应的BTS,多余的抵押的BTS还给空仓所有者。之后,只有系统拥有bitCNY的空仓,但这个空仓并非是足额抵押的,抵押物数量=债务量/黑天鹅价格 。此时bitCNY依然可以交易,转账,但不能借出。

现在的情况是,发生黑天鹅后smartcoin就死了,BSIP18的目的是让发生黑天鹅之后的smartcoin能够复活。具体来讲,
一是要恢复正常喂价。
二是要用一个足额抵押的空仓来取代系统的非足额抵押的空仓。

一不用多讲, 对二来说

1.随着抵押物涨价自动复活

当抵押物涨幅足够大导致系统空仓已经足额抵押了,那么发行者拿来“”系统空仓“的抵押物”,创建一个同样的空仓同时平掉“系统空仓” 的债务,之后一切恢复正常。

2.志愿者购买
当抵押物涨幅还没达到足额抵押时,允许志愿投资者提出申请,通过添加抵押物来获取全部或部分“系统空仓”,包括抵押物和债务。

Thanks @pc for all the work done on this.
I am still trying to understand all the complexity that will be brought by the planed change. I think I will vote the worker only when I am sure enough that the planed change is safe to the ecosystem.

@rnglab thanks for your input, your idea is suggestive, we need to think more and do more.

now I just share one news: last week I met the people of WanCloud under WanXiang Blockchain, They told me that they are interested in Bitshares and hope to join the Bitshares community as an institution, they will provide witness and API server service, and hope to work with Bitshaers in other areas.


1342
committee is scheduling to reduce the witness payment from 3BTS/block to 1BTS/block. it will happen soon.

details can be found here: https://github.com/BitShares-Committee/proposals/blob/master/170518_Witness_Payment_Adjustment.md

some relevant discussion can be found here: https://bitsharestalk.org/index.php/topic,24104.msg306298/topicseen.html#msg306298

I don't disagree with your request @bitcrab, I would not oppose it.

However, I would like to point out that you are not exactly setting a good example for witnesses to follow.

You were the one who helped promote the rise in witness pay and I supported you in that.

I am quite sad your feeds are broken AND you missed a huge number of blocks, that's not acting responsibly towards your role as a witness, and it makes us all look bad. Please try to do better and get your feeds running again!

I am sorry for the bad behavior of my witness in recent past.
I am not a enough skilled programmer/system administrator, and I am very busy these days, after I updated my witness node I also tried to do feeding with btsprice, but not sure what happen I kept failing to do so...
fortunatelly now in a whole the price feeding of witnesses work well so my absent do not lead to obvious worse consequence...
I'll try to fix my price feeding scripts when I have time...

now I would like to propose to adjust the witness pay to 1BTS/block immediatelly.

from March to now, the BTS price went up 10 times and the witness price doubled in BTS, generally speaking we can say that now the witness is obviously overpaid.

it is not easy to get a perfect witness pay infrastructure, and we can continue the discuss on this topic, but at the same time, I think we need to adjust the witness payment to more reasonable and acceptable level immediatelly.

the number that come to my brain firstly is 1BTS/block, in current price it means about $1720/month for a witness.

I feel this payment  is enough to pay the cost for a witness,  and I don't think $1720/month is a overpaid salary to a witness that do good job in block generation, software update, price feeding...we need to provide a good salary, not a lowest salary.

and surely this is not the final witness payment, we can review this number continuely when price change a lot. but now I think we need to reduce the price immediatelly.

it will end or at least elimate most of the complaint to current witness payment, and will save much budget for worker proposals.

and this will tell the world: Bitshares team are able to consider globally, they focus more on the benefit of the whole community but not the benefit of a small group.

any ideas? please let me know, if there's few objection, I think we can apply the proposal in short time, otherwise, maybe we also need vote to decide.

正是天街团队做的事情,
还包含:
1.账户的全局标贴,
       
Code: [Select]
        enum class AccountLabel{
            //role 0x00~0xFF
            Shop=0x00,
            Arbitrator=0x01,
            Guarantee=0x02,
           
            //taobao 0x0100~0x01FF
            ShopType=0x100,
            ShopName=0x0101,
            ShopDescription=0x0102,
            DealAmounts=0x0103,
            GoodDeal=0x0104,
            BadDeal=0x105,
           
           
            //Arbitrator 0x0200~0x02FF
            ArbitratorName=0x0200,
            ArbitratorDescription=0x0201,
            ArbitrationAmount=0x202
           
        };

2.单独的加密传输协议,
3.加密仲裁协议,

很快就可以看见测试版本了;

天街是否不改底层,只是象@abit描述的那样借助现在账户中的多重签名实现?

我想,还是应该追求链上原生实现,应该每个人都可以用自己的常用账户来直接进行这种交易,而且GUI钱包里就该直接集成交易界面。
看了一下steem的流程https://golosim.ru/escrow/index.html,感觉有点问题:

1.escrow在绝大部分正常交易中应该不需要参与,就像基本所有的淘宝交易都不需要找淘宝做仲裁,而steem的方案中要求escrow每次都要approve,没有道理。

2.应该只有一个expiration time,比如30天,如果买方发起“条件支付”之后B也进行了“交付”操作,之后再无操作的话那么30天后资金自动从买房发送到卖方,就像淘宝一样。

感觉与这种交易配套,最好每个账号有一些字段储存个人信息,如微信账户,电话,支付账户等等,只有条件支付的对手方能看到这些信息,不过这样复杂性似乎又高了

1347
我强烈地感觉到,在所有讨论过的新功能中,“条件支付”是目前最急迫需要的功能。

我们先看一下以下两个最适配也最需要解决方案的场景:

1:人人网关
2:BTC场外交易

还有以下不是最紧要但也可能适配的场景:

1.跨境商品交易
2.全球任务外包

作为交易,这些场景能够抽象出一种最基本的特点,就是在链上完成一个方向上的支付,然后另外一个方向上的交付在链下完成。

自然,这种交易没法直接在链上实现原子化,必须依靠某种确认+仲裁的机制才能保证正常进行,A先“条件支付”一定数量链上资产(如bitCNY)给B,同时在memo中描述清楚无异议的交易条件,选择仲裁账户C,支付,此时支付的链上资产被系统锁定。

B看到A发起的条件支付交易,在认可交易条件的前提下,在链下完成约定的交付,并且对条件支付交易进行“交付”操作(类似淘宝卖家的发货)

A对链下的交付结果无异议,对条件支付交易再进行一次“确认交付”操作(类似淘宝买家的“确认收货”操作),则锁定的资产将释放给B。交易完成。

如A条件支付后因某种原因需要取消交易,则进行“取消交易”操作,经B确认后锁定的资产退还给A,类似淘宝交易中的退货。

如果交易中发生争议,则有仲裁者C来选择支持某一方的立场,最终锁定的资产按改方立场分配。

当A发起条件支付交易时,交易对手方可以是空的,比如人人网关的场景下, A可以支付1000bitCNY给一个空账号,同时注明:995元出售,支付宝账户***,此时任何人可以选择接受此交易并通过支付宝支付995元来获得1000bitCNY,这就是人人网关。

随着BTS价格的增长,人人网关的意义越发凸显,很明显在承兑的需求快速增长的情况下两条路可以选,一是象transwiser这样的网关选择公司化运营,做大做强,二是把承兑服务的提供方也给去中心化了,由用户群体自身来提供服务。我相信,这两种方式可能都需要,而人人网关尤其需要。

而且,有了条件支付功能,BTS直接就是一个去中心化的BTC场外交易平台,这意味着什么不用多说了吧?

还有象跨境商品交易,国际任务外包,都有可能适配成条件支付支持的场景。

几个月前我发过一次帖子讨论这问题,结果是都觉得不错,然而最后还是感觉无从落地。。。https://bitsharestalk.org/index.php/topic,23800.msg302876.html#msg302876

这次希望中国的开发者们先能提供一些意见,尤其是在开发和实施的可行性和难度,成本等方面,先给出一些意见,我也会在国际社区推进讨论,希望能逐渐选定合适的开发者来开发这一功能。

带宽似乎是有点低,API server带宽很重要

from my side it's ok to reduce the witness pay to, say, 1BTS/block.

but I do not agree that it's easy to do the witness job well enough.

responding in time, upgrading while necessary, providing exact enough price feed... always need to pay time and efforts to keep the witness running well.

now we need more good API server all around the world, I think providing good API server can be a plus for a witness.
