General Discussion / 2020-10-14 Old bitCNY parameters adjustment
« on: October 14, 2020, 10:21:35 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:
MCR has been increased from 185% to 195%
MSSR has been increased from 150% to 151%.
MCFR has been increased from 6% to 8%.

Current parameters:

ICR (Initial collateral ratio) 295%
MCR (Maintenance collateral ratio) 195%
MSSR (Maximum short-squeeze ratio) 151%
MCFR (Margin call fee rate) 8%
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:

* As of writing, market trading price of BTS on CEXs is around 0.13 CNY, the collateral ratio (CR) of the debt position with the lowest CR in the BitShares DEX is 109%, the corresponding black swan price is 0.119 CNY.

* 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 195% for feed price 0.22 effectively means 115% for market price 0.13, and the corresponding black swan price is 0.113.

* the MSSR value 151% for feed price 0.22 means collateral of low-CR debt positions will be listed for sale at 0.22 / 151% = 0.1457 bitCNY
** the MCFR value 8% means the price for buyers' is 0.22 / (151%-8%) = 0.15385 bitCNY

中文(Chinese) / 2020年10月14日 老bitCNY参数调整
« on: October 14, 2020, 10:12:23 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:
MCR 从 185% 上调至 195%
MSSR 从 150% 上调至 151%
MCFR 从 6% 上调至 8%

目前参数:
初始抵押率(抵押线) ICR 295%
维持抵押率(爆仓线) MCR 195%
最大轧空率(爆仓惩罚上限) MSSR 151%
爆仓费 MCFR 8%
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:
按目前外盘价0.13算,内盘抵押率最低的债仓的抵押率为 109% ,黑天鹅价为 0.119

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

195%的MCR结合0.22喂价,相当于价格0.13时要求115%的最低抵押率。
计算方法: 0.22 / 195% = 0.13 / 115% = 黑天鹅价 0.113

151%的MSSR结合0.22喂价,相当于抵押品最低卖出价为 0.22 / 151% = 0.1457
再结合 8% 的MCFR,相当于要吃爆仓单,最低买单价为 0.22 / (151%-8%) = 0.15385

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  。

为了促进健康抵押,现关闭 bitEUR(欧元)和bitRUBLE(卢布) 强清功能。

爆仓机制正常运行。

请知悉。

目前 bitEUR 共有400多万BTS的抵押仓, bitRUBLE 有200多万BTS的抵押仓。

General Discussion / 2020-10-04 EUR and RUBLE force-settment disabled
« on: October 04, 2020, 01:28:52 pm »
In order to build up more supply, it is now not possible to force-settle EUR or RUBLE.

Margin calls still work fine as before.

As of writing, there are 4,364,631 BTS in collateral for bitEUR and 2,057,592 BTS for bitRUBLE. IMHO these two assets have potentials to develop better.
