It's always great to see new people get involved with Bitshares. Welcome!

For the most part witnesses are required to:
- Have a TESTNET witness
- Maintain a seed server
- maintain an API
- provide price feeds for the committee smartcoins

all that in addition to the witness server itself.
Please add your information to the Bitshares Github (seed and API). Once all that is complete I will be happy to vote for your witness!

Supported. But it seems that we are lacking support from a group of folks that constantly twist your (@xeroc) arm to support their changes but don't support or even don't comment on other initiatives.

Even though currently the DEX price more or less reflex the market price; based on buys and sells it can spike significantly in relation to global markets. And of course we can't just feed the DEX price by itself. I have been working on my tuning my prices a bit. I  have also noticed that GDEX updates their price feeds every 2 minutes. Is that were we are trying to go with this? Provide frequent up to a minute feeds?

If we all agree that MSSR should be 0%, MCR at 1.0 and force settlement as high as we can (100%?), we should be able to get everyone creating some bitCNY, but who is going to buy it? I would rather see a bit smaller MCR than non-existent MSSR.

you misunderstood what I mean. I don't forget the basic financial principle.

I don't think MCR can be reduced to 1, in my view, it is possible to go down to say 1.5 or 1.4 and stay there without going down.

MSSR is possible to go to 1, but need step by step.

force settlement offset is not supposed to go as high as possible, I don't think there is a "the higher, the better" logic for this offset, actually, now 2% for bitCNY is as low as possible, as up to now we do not have an always reliable feed price.

The last line is a joke. Of course we can't have those settings.
If we worry about MSSR than we are already assuming that longs will loan BTS at exactly 1.75. The MSSR is necessary to protect from the global settlement so let us assume that we are not changing it. If longs argue that the price on the DEX fluctuates let's say 2% and they margin called because of the wrong price we could adjust MCR by 2% to 1.71, but then in few days we will have arguments that the price is wrong again so we will need to lower it because people will ride the 1.71 border line and so on.

I am just saying that based on the market, past performances and usefulness of the smartcoins we need to come up with MSSR, offset and all other parameters that prevent global settlements and provide acceptable solution for longs and shorts.

First off, I would like to say that it is important to me as a witness to do as much as I can to help Bitshares and businesses based on Bitshares to succeed. You and other companies put a lot of work into this and by no means am I ever trying to intentionally derail those efforts. You can rest assured that I care about all my feeds and I want them to be as accurate as possible (thus the paid services), and I do that across all price feeds on the DEX. In the past few months we have done a lot of changes on the Bitshares to accommodate BSIP42, MSSR changes etc. Sometimes I don't agree with those changes but as the witness I follow the majority (or whatever proposal gets voted in). As an example I wrote a warning about BSIP42: https://bitsharestalk.org/index.php?topic=20792.msg322796#msg322796 and a Black Swan on bitUSD and unfortunately we did have the Black Swan because BSIP42 was voted in.
I started to monitor my CNY feed more closely and will work with it to make sure that the feeds reflect true pricing from the markets. But let us remember that few months ago price feeds were within 4% range from the median and now most of the feeds are within 1% with spikes to 2%. The DEX with a settlement of 24hrs was not designed for REAL TIME PRICING, most witnesses feed every 20 -40 minutes.

2nd off this is just a personal comment, I think all witnesses have an obligation to provide a reliable infrastructure and price feeds for ALL committee owned smart coins. Is it too difficult for some to provide more than 2 price feeds?

and 3rd off, just wanted to say that your approach to constantly vote and unvote witnesses to pressure them to see things your way is not really well received. I think we are all open to conversations to make things better and improve on the things that we do, because as I said; we all want Bitshares to succeed and bitCNY is big part of that.

Looks like you updated your account on your own proposal so nobody should steal your coins. The only change I see is that you added a 66% authority to your account jimbo9899 so if you can get to your wallet an unlock it you should be able to remove that from your owner permissions.

Hi Xeroc,

You have removed your support for my witness sahkan-bitshares on 20 DEC 2018 (the day the blockchain crashed). I just wanted to request that you consider re-voting my witness. Thank you for you past support!

revoted. You've done a good job so far .. as it later turned out, the crash on december was not due to witnesses not upgrading their software in time - which was what i believed when i remove my vote from your witness (among others)

Thank you! Also just republished the price feeds as they were above the threshold for the auto update; they are back to auto feeds again.

Witness sahkan-bitshares is using Zapata's script to provide the bsip price feeds. In addition to the script I utilize paid services from currencylayer and bitcoinaverage for more reliable currency pricing and increased api availability with closer to real time market pricing.

On second note, I believe that transparency or not, witnesses' job is to provide price feeds in accordance with current rules (ie BSIP42) and it should not matter if a particular witness agrees with it or not. This should also be true for the future, if there are any changes that are voted in, the witnesses should provide data according to those changes. What I don't agree with is making changes without voters approval.

price feeding is so important for Bitshares and it need witnesses to pay more attention and efforts on this.

witnesses need to publish their algorithm to for voters to evaluate and check with the real feed price.

the published algorithm need to include

1. how the premium is calculated out.
2. how the feed price is calculated out based on premium and other factors.

I am sorry that I'll use my voting power to push this thing, after 20th, Nov, I may update voting on witnesses if the behavior on this is not satisfactory.

I agree transparency on pricefeed is a must.

You can find the up-to-date details of my algorithm there.

Note that, I always tryed to be the more transparent as I can:

• My algorithm and the various changes are discused in my application thread.
• My pricefeed code is public, and I always used the public version of the code.
• I've build a tool to help shareholders to monitor the witnesses prices over time, and compare against each other, median feed/dex/cex prices.
