General Discussion / Re: Announcement on BSIP42 relevant actions

1) Do you support an experimental MSSR of 0 as an incentive to keep shorts in the game and not penalize future bts collateral holders?

Yes. The current price feed modification is interfering with the MSSR in a bad way that renders the intended penalty moot and leads to a price feed that is further away from the real price than necessary.

We cannot aim for a tight peg *and* force margin calls to buy above the market price, at least not without a hard fork.

now I feel to reduce MSSR make sense even after the implementation of BSIP42, and I don't think setting MSSR=100% means the penalization is cancelled, forcing one user to sell it's collateral in market price is still one kind of penalization.

there is another BSIP for setting MSSR to 105% for bitCNY, https://github.com/bitshares/bsips/issues/97, however it is not moved forward when BSIP42 is on the way.

This OP on bsip42 has veered wildly off the original subject.  Nice to see the creativity, althought there are some misconceptions floating. I would like to know people's opinion on the following.

1) Do you support an experimental MSSR of 0 as an incentive to keep shorts in the game and not penalize future bts collateral holders?

2) Is a dynamic MCR feasible?  What parameters would you like to see for this?
2a) for the skeptics out there remember bitUSD is not quantitatively more sound by having 1.75x vs 2.8x collateral in the pool.  The key metric is a collateralization >= 1 x smartasset denomination.  If an asset can have a slightly lower collateralization (with sufficient safeguards) it may increase supply and robustness of the trading market.  This may lead to second order benefits and harden the economy/strength of bitUSD.

IMO the conversation surrounding bsip42 is an indication of the synthetic price setting mechanism overpowering the natural market price setting mechanism.  It is totally understandable that in a prolonged bear market fewer trading activity will happen and irrational spreads will occur.  Rather than solving this synthetically with price feeds perhaps the ecosystem would be better off focusing on driving fundamental growth and trading activity around smartassets.  Let us what the market thinks of bitUSD when we get more unique users. 

I think between the two options in Jerry's OP, a slight modification to MCR (done responsibly and transparently) is in better keeping with the implicit social contract that bitCNY/USD holders/shorters made when they engaged the platform.

大跌行情,外盘领跌,外盘价低于内盘价。

因为bitUSD溢价基本是靠比较内外盘价格来计算,所以这种情况下,算法认为bitUSD有折价,开始向下调喂价。

于是,要么引起不断爆仓,要么内盘把价格砸下去让算法觉得bitUSD有溢价,保持喂价。

不是说不能接受爆仓或者内盘价格下跌,但问题是,这种情况下通过简单比较内外盘价格来判断溢价是有问题的。

需要发展更好的算法来判断溢价/折价。
没感觉有问题呀。
当出现差价,如果搬砖不能搬平,那么就是存在折价了。
流动性差,搬砖渠道不通畅,价差会存在较长时间。

但价差和bitUSD溢价未必是等价的,虽然内外盘价差较大,但没看到bitCNY/bitUSD汇率有较大波动。

要努力让bitUSD/BTS交易对与外盘联动才行。。。

前面已经达成共识的一点是喂价不能低于市场价,前些天个别见证人喂价一直低于市场价是不能接受的。


这段时间以来的实践所表现出来的负反馈的一个弊端需要解决,虽然负反馈在价格下挫过程中起到了好的效果,但在价格上升过程中,负反馈使内盘完全变成了一个被动盘。内盘具有最高的流动性,理应更具有定价权和价格发现功能,但负反馈导致内盘主动拉盘就会造成喂价反向降低,结果就是我们看到的自实行负反馈以来,内盘越来越死气沉沉,刚开始实行负反馈时BTS市值排名提升了4、5个名次,现在又完全还回去了。或许需要下跌与上升时不同的反馈算法来解决这个问题。

I will add to my post above.
I wanted to say that you are putting an end to bitcoin (providing bts) which is better than the dollar and fiat money by a margin rate of> 1 (current 1.75)
it's a dead end

Transforming Businesses with Blockchain: Interview with Ronny Boesing for TechBullion



Openledger ApS brings to the blockchain market; the OpenLedger DEX, a place to trade cryptocurrency and tokens. In addition to that, offers a custom blockchain development to businesses and helps startups raise capital through token sales. In this interview, Ronny Boesing, the founder and CEO of OpenLedger Aps will be discussing the project with us and the opportunities available.


OpenLedger R&D department spends a lot of time working with clients to make sure that we have the right solutions – this is usually the longest phase, as we’ll want to ensure a perfect fit before we start moving forward on development and deployment.

OpenLedger ApS offers these products and services:

*OpenLedger DEX: A decentralized trading platform that runs on the blockchain so it never goes down and can’t be hacked. Stablecoins, tokens, coins from many blockchains can all be exchanged safely.

*White label DEX: B2B-oriented option to white label the versatile OpenLedger DEX. Add your branding, icons, coins and payment options.

*HubDSP: programmatic advertising built for blockchain companies and projects, putting ads in the right places and in front of the right eyes. All the control and versatility you’d expect from a demand-side platform, unique blockchain focus.

*Bitsharescan: Blockchain explorer and analytics platform for the BitShares blockchain.

*OpenLedger DEX Mobile Wallet: Free Android and iOS mobile app that lets you sign into your existing crypto wallet(s) on the move.

*OCASH: upcoming debit card (we’re still working on this one!). It will provide users with seamless payments in both fiat and cryptocurrencies.

ICO consulting: All aspects of ICO from selecting the right blockchain to PR and marketing, escrow and ongoing tech support.

*Custom blockchain development: If you don’t see what you want on the market, we can build your own blockchain for you from the ground up.

*genEOS: genEOS building a full-stack business ecosystem, complete with operating system-like development environment, based on the EOSIO software.  We’re advisory partner in that project.

OpenLedger DAO Space: A DAO is a Decentralized Autonomous Organization – a virtual organization, governed by its members. Still in development, OpenLedger’s DAO Space is a place where these organizations can be conceived, developed, tested and launched. By the away, the very first version of DAO Space is available for the OpenLedger DEX users.

Why pay for SSL certs when you can get them for free using certbot?

I'm not sure of the neccessity of the newsletter, email nor professional inquiry panel, these feel like centralizing BTS around this website.

1) Paid SSL at inbound price of 10ish Dollar per certificate for a year with signature of the domain on it is not same security as free ssl certbot.

2) Newsletter is common in any normal business in the world. Its being used for signups and monthly notifications to its clients/partners.

Everything but "centralizing" is included in this worker.

Many thanks for your opinion and support.

1> Cost of certs is no big deal here. I agree with @customminer LetsEncrypt / certbot is free and reliable (I use LetsEncrypt with getssl bash script on all of my nodes, have used certbot in past also, but more options I don't need with certbot)

2> I would say the newsletter is worth trying out to see if many find it useful. If not it should be discontinued. Jonathon Ba'hai and CryptoPrometheus created a very nice newsletter which the community really enjoyed. It became too time consuming to manage as content was growing rapidly. They also wanted to start building a replacement tool called DPOSHUB which launched but never really went anywhere.

Love your work on the new site and if Micheal doesn't vote for it I will temporarily remove him as proxy and vote for it directly myself.

当出现差价,如果搬砖不能搬平,那么就是存在折价了。

一段时间来的喂价实在看不懂啊,前面外盘价格基本稳定,喂价一直在降低,直至到昨天喂价低于内外盘市场价,今天市场价大幅降低,喂价反而仅仅小幅降低,就像市场没有暴跌一样。


题外话:这种喂价变化,还不如在MCR不能调整的现阶段,将喂价在外盘价基础上直接加10%更好,这样至少喂价变化规律是确定的。
以前外盘大跌,内盘喂价跟着大跌,大量爆仓。

现在外盘大跌,内盘小跌,少量爆仓,
其实可以理解为:外盘大跌,内盘喂价跟着大跌,大量爆仓,导致bitCNY溢价,所以喂价上调,爆仓减少,最终达到平衡。

也就是说,负反馈算法反应的比你想象的快一点,跳过了大量爆仓的步骤,直接达到了平衡。

一段时间来的喂价实在看不懂啊,前面外盘价格基本稳定,喂价一直在降低,直至到昨天喂价低于内外盘市场价,今天市场价大幅降低,喂价反而仅仅小幅降低,就像市场没有暴跌一样。

现在的喂价属于阴跌姿势~~外盘暴跌,喂价中跌。 外盘暴涨,喂价中涨。外盘横盘,喂价就阴跌。
昨前天喂价低于外盘市场价可能是因为bitcny充值手续费率为0或为负...然后充值手续费这个目前来说太好操作了,鼓鼓承兑商充值手续费最低的几个,总共bitcny就几万,十几万。
然后AEX bitcny:cnc交易 机器人一直0.997。0.998的刷单。负反馈就会认为bitcny<1人民币。就直接降喂价。 最终阴跌到低于外盘市场价。


1.喂价脚本并不都是取鼓鼓手续费的;那些取鼓鼓手续费的,也是按成交量加权,而不是看当前挂单手续费:有成交基本可以说明价格真实。

2.喂价脚本并不都是取aex的成交价的;aex机器人刷得动,说明没足够买单把价格推上去,所以价格基本真实。

3.是否折价,不只是看bitCNY和CNY的直接兑换价,还有个判断依据就是对比内盘的BTS/bitCNY价格,和外盘的BTS/CNY均价或全盘BTS均价(受USDT、USD汇率和BTC价格波动影响),要操作这个还是有点难度的。
直接兑换价因为充提/交易手续费的关系,存在盲区。
