BAIP: 0002
Title: Reform of loopholes in feed price mechanism
Authors: cn-vote  [email protected]
Status: Accepted
Type: Consensus 
Created: 2019-10-22

Abstract

This BAIP defines reforms to the current feed price mechanism vulnerability. The specific program is: The feed price is the highest between the current price and the two-day moving average price .

Motivation

After the failure of BSIP42, the current feed price mechanism has major loopholes and serious negatives, many cex exchanges use our vulnerability to maliciously short,which seriously damaged the ecological balance, which caused us to suffer many unnecessary losses and hindered the development of the entire ecology.
When the vulnerability has been expanded to be intolerable, in an emergency, the passage and execution of BSIP76 has temporarily blocked the expansion of the vulnerability. However, the current feed price mechanism is still in urgent need of reform.

Rational

"The feed price is the highest between the current price and the two-day moving average price ".
This BAIP does not conflict with the previous consensus on the feed price of all the communities. The feed provider continue to collect the feed price according to the original community consensus, and the community consensus on the protection of the black swan(BSIP58) and the minimum feed price is continued(BSIP76).
This BAIP only requires the introduction of the abstract described in the feed price script, which is
"The feed price is the highest between the current price and the two-day moving average price ".

Specifications

Implementing measures

If (current price >  two-day moving average price) {
  feed price = current price;
}
Else{
  feed price = two-day moving average price;
}

Noun explanation

• Current price : The real-time feed price of the current feed price mechanism before the reform.
• Two-day moving average price : two-day moving average price =( current price (1) + current price (2) + current price ( 3) ...+ current price (n) )/n.
  • n is the sampling frequency, which is 48 times, that is, n = 48*m; m is positive: m = 1, 2, 3....
  • current price (k) is the current price at the time of sampling. The current price (1) is the
    current price at this moment. The current price (n) is the current price at the time of 48 hours ago.
  • Sampling interval (in hours): sampling interval = 48 / n = 48 / (48 * m). That is: m = 1, two- day moving average price every hour to sample once,;m = 2, two-day moving average price half an hour to sample once, And so on.

supplementary explanation

To decide whether to reform of loopholes in feed price mechanism, 2 poll worker proposals will be created for voting:

• Poll-BAIP**- Reform of loopholes in feed price mechanism.
• Poll-BAIP**-Not reform of loopholes in feed price mechanism.

If the voting confirm the change, committee will announce the change at least 3 days before the change is implemented by feed provider.

Summary for Shareholders

This program is simple and effective, and can prevent malicious short-selling or increase malicious short-selling costs to a certain extent.

Active, any questions here can be answered

[grctest]

That's not true, the majority of the BAIP2 file is not available to be commented on in the 'files changed' section. Answer the questions in #9 than dodge them - if they hold no validity then surely it'd be simple to respond to them?

I think the content of BAIP002 is very complete.
In fact, this plan has been discussed in the forum for more than a month.
We should not stay in endless discussions without doing anything of practical significance.

I think the content of BAIP002 is very complete.

I disagree, at the very least there are multiple grammar errors.

We should not stay in endless discussions without doing anything of practical significance.

Then address comments in the pull request review process than disregard BAIP processes. Being unable to directly defend ones own work is concerning & indicative of poor quality.

[abitmore]

@grctest would you like to create a new pull request to correct the grammar errors so we can go forward? I guess it's too hard for the original author(s) since his/their English skill is not as good as yours.

[grctest]

Given the direct threat of legal action by the author, no.

My original pull request comments are still there if anyone's interested.

What examples do you have of malicious shorts?

This BAIP failed to prevent the price feed threshold workaround from BSIP76 from needing to be activated for a second time.
