General Discussion / Investigating the reasons for BitUSD GS
« on: December 06, 2018, 03:12:04 pm »
Greetings, Bitshares community!

A very few of you may remember me from the early days of Bitshares; back then, I was a lowly graduate student interested in game theory and cryptocurrencies.

Now, I've worked my way up to professor of Computer Science at the University of Colorado: I've been doing a bit of research on stablecoins recently, and I want to gather some perspectives on what went wrong with BitUSD. I think there are some very interesting underlying problems with stablecoins in general (see NuBits for some early examples), and collaboratively-managed stablecoins in particular (see BitUSD), and I'd like to understand these problems very clearly.

So I'd love to get some community input on the reasons that BitUSD's peg mechanism broke and it went into GS. Here are some starter questions, but of course give me your own perspectives even if they don't fit my questions at all:

1. Was BitUSD mismanaged? If so, by whom and why?
2. Was it the fault of BSIP42?
3. How will BitCNY be saved from the same fate?
4. Was the GS inevitable?

And just to be clear about my intentions here, depending on my findings, I plan to write a (possibly series of) academic research papers on the topic of how to properly incentivize stablecoins. I think the incentive issues are very deep and likely very difficult to surmount. Here's an older summary of my concerns:

I'm trying to compile a good record of my Bitshares activity, and the web wallet doesn't give you much history. Does anybody have a nice CSV history service or anything? Or a better web interface that lets you download history?

CCEDK / Why are STEEM/SBD withdrawals disabled?

It's all in the title. It would be a nice customer-relations move to have a banner of some sort on markets whose deposits are disabled. Sure, buyer beware and all that, and I'm not threatening to libel you or anything - but it's extremely frustrating to find what looks like a good price only to discover too late that it's because the IOU in question isn't actually redeemable at the moment.

General Discussion / BitCNY Price discrepancy
« on: June 21, 2017, 11:15:33 pm »
I have been watching the BitCNY price slide downwards relative to bitUSD for the past several weeks. Right now, by dividing bitUSD and bitCNY price feeds, the implied bitCNY/bitUSD price is about 0.133. On the other hand, Google gives the exchange rate between CNY and USD at 0.146.

Why the discrepancy between exchange rates?

Technical Support / Force settlement offset
« on: June 19, 2017, 11:42:53 pm »
The big smartcoins all seem to have a parameter called "force settlement offset" set to 1%. What is this? Does it mean that you get only 99% of the face-value BTS when you request a settlement?

If so, what is the purpose of this?

Technical Support / Public API for bitshares?
« on: June 15, 2017, 08:35:19 pm »
I'm putting together a python tool to look up all my trade history for all my cryptocurrency holdings, and at some point I'll need to get my Openledger stuff in on the action. Is python-bitshares the right tool to use, and is this an appropriate thing to use public APIs for? Are the public apis that the web wallet connects to good for this sort of thing? I know in Steem it matters which plugins the node is configured for, and I'm not familiar enough with the Bitshares backend to know exactly what questions to ask here.

Howdy all - I just posted the following on Steemit:

I'm cross-posting here because I'm sure people here will know the answers:

What I'd like to do, but am not sure how:
I want to save my old BTS owner key somewhere and then update the BTS owner key to a new one. Once it's updated, the old key won't give access to the account, so I can go and drop the old key into the peerplays wallet without fear of unforseen security leaks.

How is the BTS owner key changed? I've looked at the permissions tab in the wallet and it's not obvious enough to me to be worth going and modifying all my permissions.

Technical Support / How do I refer users?
« on: October 15, 2015, 03:21:25 pm »
I bit the bullet and got a lifetime referral membership, because they're only $50 right now. How do I refer people? I keep thinking this MUST have been answered somewhere else, but I couldn't find it.

Muse / Will NOTE snapshot include active DEX orders?
« on: October 06, 2015, 07:04:43 pm »
I have a couple orders on the DEX to sell some NOTEs - will the snapshot capture those, or do I need to cancel the orders before hand? Thinking more about it, I'll probably cancel them anyway just to avoid any weird disappointments, but I thought I'd ask anyway.

General Discussion / The market engine is not matching shorts properly
« on: April 10, 2015, 10:35:01 pm »
Right now, there are bids for BitUSD above the feed price. The feed price is about 211, the highest bid is 225. To test the market, I shorted BitUSD with 1000 BTS of collateral, and was able to borrow 2.3637 BitUSD. Now in my margin order it says I have about 1500 BTS, which means the proceeds of my short order were about 500 BTS. THAT IS THE WRONG AMOUNT!! I should have been matched with the highest bid and gotten the 225 price, but as you can calculate (500/2.3637), I only got the 211 price. I'm guessing I matched one of the many expired shorts.

I know the devs aren't allowed to talk to us anymore or some such insane bullshit, but is there anybody out there who knows how to get a fix for this in the pipeline? Thanks.

Muse / NOTE Price discussion
« on: March 26, 2015, 03:17:59 pm »
Has anybody done any ROI calculations for NOTEs from the pre-sale? I can't recall my ballpark figures exactly, but it seems like the pre-sale was implying a market cap around $2MM, which isn't far from where NOTEs are trading now. Anybody care to give actual numbers?

Last week I'm quite sure I sent a deposit of 13,396 to Bter. I have screenshots of my client with all the "btercom" transactions filtered out, and my deposit shows up in that list.

However, Bter tech support tells me it's not showing up in the Bter wallet! Does anybody have any idea what this could mean? The txid prefix is 142a3e31, and you can see it's a transaction in this block:

Is there anywhere my deposit could have gone except to Bter? Does Bter need to re-scan? This happened around the time 0.5.0 came out; maybe the deposit came in while they were updating and somehow didn't get scanned properly by their wallet?

Is there a way they could scan my transaction in particular to verify that it's to them?

General Discussion / Bter deposits stuck?
« on: January 20, 2015, 10:14:56 pm »
Anybody else having problems depositing BTS to bter post-hardfork?

Does anybody here have much to do with Gliss from CMC? We should ask him to include this trading pair in his BitUSD price/volume calculations:

There seem to be at least 2 market maker bots running on that pair, and volume is picking up.

General Discussion / Making the BTC/BitUSD market on Bter
« on: January 01, 2015, 09:37:28 pm »
Hey all,
Just wanted to let the community know that I've started attempting to add some liquidity to the BTC/BitUSD trading pair on Bter: I haven't put much money on there, but I'm hoping that the trading pair gets some action and I end up getting the opportunity to put up more cash.
