我认为在抵押排名第一的实际抵押率下降到合适的抵押率之后，可以尝试解锁喂价，需要喂价人提前做好黑天鹅防护脚本以应对外部市场变化。

解锁前操作：
1.ICR与MCR保持不变，限制总量不变；
2.MSSR下调至1.01，MCFR下调至1%；
3.解锁喂价+黑天鹅保护

解锁后操作：
1.分别降低ICR与MCR；
2.解总量；
3.在爆仓单彻底消除后，调整MSSR到1.1，MCFR至9%；
有道理。

General Discussion / 2020-10-11 Old bitCNY parameters adjustment
« on: October 11, 2020, 09:22:29 am »
Purpose:
to restore the peg of bitCNY in the long run and mitigate the issue that some debt positions' collateral is too low.

Changes:
ICR has been increased from 275% to 295%;
MCR has been increased from 175% to 180%, later increased to 185%;
MCFR has been increased from 5% to 6%;
Maximum supply has been reduced from 35,000,000 to 28,000,000.

Current parameters:

ICR 295%
MCR 185%
MSSR 150%
MCFR (Margin call fee rate) 6%
FSO (Force settlement price offset) 2%
FSFP (Force settlement fee percent) 1%

The median feed price is 0.22 CNY/BTS.

Borrowing has been enabled earlier. The maximum supply is limited to 28,000,000 bitCNY.


Note:

* the ICR value 295% for feed price 0.22 effectively means 174% for market price 0.13, and the corresponding black swan price is 0.075.

* the MCR value 185% for feed price 0.22 effectively means 109% for market price 0.13, and the corresponding black swan price is 0.119.

* the MSSR value 150% for feed price 0.22 means collateral of low-CR debt positions will be listed for sale at 0.22 / 150% = 0.1467 bitCNY
** the MCFR value 6% means the price for buyers' is 0.22 / (150%-6%) = 0.1528 bitCNY

I can help out with the feeds.
Any update please? I've added you as a feed producer but you've never published feeds?
I am out of active witness rotation. Hard to plan and jump on anything if my witness gets voted in on random few days out of a year.
I voted for you after 5.0 launch because I wished that you could participate more in the ecosystem.

I removed votes from you a few days ago because I hadn't heard from you in a week since you replied here that you can help out.

BTW if I am correct, you are not running any service except a block producer for the blockchain at this moment. No API node, no seed node, no price feeds, no other contribution that I can see. If you start to participate more I would like to support you, otherwise I am sorry.

Anyway, thanks for your contributions in the past.

中文 (Chinese) / 2020年10月11日 老bitCNY参数调整
« on: October 11, 2020, 09:01:40 am »
参数调整目的：争取恢复 bitCNY 锚定，缓解部分借款仓位抵押率过低的问题。

今日操作：
ICR 从 275% 上调至 295%
MCR 从 175% 上调至 180% ，后提高到 185%
MCFR 爆仓费 从 5% 上调至 6%
债务上限从 3500 万 bitCNY 下调到 2800 万 bitCNY

目前参数：
ICR 295%
MCR 185%
MSSR 150%
MCFR 爆仓费 6%
强清价格偏移 2%
强清费率 1%
喂价 0.22 暂时保持不变

借款功能目前开放，债务上限 2800万 bitCNY

注：
295%的ICR结合0.22喂价，相当于价格0.13时要求174%的初始抵押率。
计算方法： 0.22 / 295% = 0.13 / 174% = 黑天鹅价 0.075

185%的MCR结合0.22喂价，相当于价格0.13时要求109%的最低抵押率。
计算方法： 0.22 / 185% = 0.13 / 109% = 黑天鹅价 0.119

150%的MSSR结合0.22喂价，相当于抵押品最低卖出价为 0.22 / 150% = 0.1467
再结合 6% 的MCFR，相当于要吃爆仓单，最低买单价为 0.22 / (150%-6%) = 0.1528

中文 (Chinese) / Re: 比特资产 1.0 版 重新启航，喂价人招募帖
« on: October 10, 2020, 10:56:45 am »
今日更新：

新建资产 1.3.5866 RUB1.0

新 RUB1.0 资产包括之前的6个资产，放弃如下参数调整权限：
* 发行人可将资产收回（强转），目前参数关闭（也就是说不可强转）
* 所有转账必须通过发行人审核同意，目前参数关闭（也就是说可以自由转账）
* 禁止强清，目前参数关闭（也就是说允许强清）
* 允许发行人进行全局强制清算，目前参数关闭（也就是不允许理事会主动发起全局清算）
* 禁止借款，目前参数关闭（也就是允许借款）
* 禁止调整供应量上限，目前CNY1.0参数关闭（也就是理事会可以调整CNY1.0供应量上限），其他资产参数开启（也就是理事会不可调整供应量上限）

注：CNY1.0的供应量上限参数是由于误操作导致不可禁止调整。目前供应量非零，无法修改。正与社区协调，期望可以修复。

另外，补充前日更新：
* 放弃如下参数调整权限：调整 ICR、调整MCR、调整MSSR

General Discussion / Blacklist managed by the committee to combat phishing attacks
« on: October 07, 2020, 09:06:53 pm »
A new "committee-blacklist-manager" account has been created to fight phishing attacks.

613 accounts have been added to the list (source https://github.com/bitshares/bitshares-ui/blob/develop/app/lib/common/scamAccounts.js).

The blacklist has been enabled on major committee-owned assets.

It's recommended that gateways and other businesses add that account as one of their assets' blacklist authorities.

HOWTO: in the reference wallet, "update asset" page,
  • flags - Require holders to be white-listed
  • Whitelist - blacklist authorities - add the "committee-blacklist-manager" account

For command line, add 2 to "flags", and add "1.2.1793420" to the "blacklist_authorities" array.


If found a phishing account is missing in the list, or found a new phishing account, please report here or on Github https://github.com/bitshares/committee-tools/issues/new .

If found an account in the list is not a phishing account, please appeal here or on Github too https://github.com/bitshares/committee-tools/issues/new.

中文 (Chinese) / 钓鱼账号黑名单
« on: October 07, 2020, 08:50:21 pm »
为尽量减少用户被钓鱼攻击的现象，理事会已新建账号 committee-blacklist-manager 用于集中管理黑名单。

目前黑名单中已有 613 个账号，数据来源为 https://github.com/bitshares/bitshares-ui/blob/develop/app/lib/common/scamAccounts.js

主要理事会资产已经启用该黑名单。

建议各网关、项目方将该账号添加到各资产的黑名单管理员名单中。
具体方法为：在网页钱包中，更新资产界面，
  • “活动标记”标签 - 要求资产持有人被列入白名单；
  • “白名单”标签 - 黑名单权限 - 添加 committee-blacklist-manager 账户。

如果用命令行操作，则将 flags +2 ，且 "blacklist_authorities" 数组增加 "1.2.1793420" 即可。


希望社区共同维护该黑名单，如发现遗漏的或者新的钓鱼账号，请及时举报。

如有账号被错误添加到黑名单的，请发帖或回帖申诉，或者在 Github 上提交 issue ，地址 https://github.com/bitshares/committee-tools/issues/new  。

Time will tell.
I also think it will increase the circulating supply, but it is not a long term solution for a healthy market. Higher FSO, could also allow bigger discount and higher arbitrage activity.
I've never said it is a long term solution.
Parameters can always be adjusted again as situation changes.

Liquidity pool fees:
create: 50 BTS
too cheap, 250-500BTS is fair
I don't think so.
For every liquidity pool, an asset need to be created, which is at least 965 BTS of fee (1/2 for non-LTMs due to initial fee pool, 1/10 for LTMs).
