still waiting for GUI release, but the Tui is used for testing and is fully connected to the InstantDEX API

I got the ordermatching working, along with order expiration, so it is theoretically functional now. Of course it needs to be tested first

James

Here is debug Tui by cryptosleuth:

For anyone who's missed it:

Win free SuperNET by performing social actions (Tweet, follow, etc.)

3 Days left to Enter!

finally got the order matching to pass all the checks and do an order. it is quite a few checks that need to be passed
also have multiple orderbooks autocreated so soon we can get a combined orderbook from many sources

James

it would require someone that knows code to verify, but it was very small changes to reactivate InstantDEX as it has been 90% complete since summer.
just so many things happening...

anyway i am the turtle. zoom zoom

James

GUI is based on yunbi.com/markets/nxtbtc, we are removing the centralized stuff. I wanted a GUI that is familiar to users.

The v1 GUI is in very active testing now, but that is just the first part of the iceberg as the InstantDEX is developed independent and then it gets merged in. Along with all the other projects, so it is confusing to those that want to buy the rumor and sell the news as there is always things happening

James

nice, everything is starting to fall in place now )

not long until a nice looking gui is on the way i guess? if possible maybe something like https://beta.bittrex.com/ ; it is down right now, but looks really good and alot of extra information!

Turkish for me, but it looks nice

This is a text based GUI for InstantDEX API that we will use for testing:

nothing fancy, but will allow for realtime order entry and trading. So we are going full speed ahead with the InstantDEX testing and hope to have the low level rock solid for when the graphical user interface is ready

James

Let's get the word out!
SuperNET's set up a Twitter/FB Action Campaign at
http://promoplugs.com/Campaign.aspx?CID=139

Takes seconds to complete all the actions, and you could win free SuperNET!
I'll add actions pertaining to the recent developments as soon as they're released!

This is front page crypto news! History in the making! 

This is a huge development for SuperNET, Nxt and crypto as a whole. If we can move a decent proportion of trading onto InstantDEX it will be beneficial for everyone. Very exciting times.

fixed fees coded and spot tested.

now InstantDEX (and therefore SuperNET) has a monetized decentralized service coming soon. just need to get the GUI yunbi.com/markets/nxtbtc to be ported

still many things to get done, but i am pretty sure I will be able to keep up with the GUI side, so another few days and I should get InstantDEX into maintenance mode too (along with ramchains and MGW that are already there)

then it will be onto Tradebots and deploying automated market makers for the 1% spreads on the supported markets

James

I am putting in a fee of 0.1% (1 / 1024) for InstantDEX trades. There are no fees for making or canceling bids/asks, but I am really concerned that if InstantDEX trading is becoming very popular it will saturate the NXT blockchain.

at 64 trades per block, we fill up the current blocks. So for spam protection and to preserve the blockchain space we need some sort of fee.

However, I dont want the fee to be too high that it discourages trading. Initially, for trading crypto the MGW has to be used, but for asset <-> asset trading, this can be done directly without any MGW involved (unless you are trading against mgw BTC)

Due to the lack of blockchain space, I am now advising to keep the txfee at 1 NXT. Assuming we fill up the blocks, this is ~250K NXT in fees per day (gladly paid by traders). Now at this pace, NXT forging is paying ~10% per year! I think with that sort of return, the value of NXT will become quite a bit larger.

James

P.S. for those trying to estimate the amount of fees InstantDEX will earn I would imagine it would be a multiple of the 4NXT worth of fees per trade. While most trades will be < 1000 NXT, there will be some larger trades for 1 to 10 BTC


*********
I am also considering a flat fee of ~5NXT. This further discourages small trades and will be a much better deal for the larger trades and it is easier to keep track of without ending up with a zillion different assets

UNITY itself is the SuperNET asset and you dont directly use it, so it is best to just have it in a NXT address that you control. All dividends will automatically be sent to whatever address the SuperNET asset is in. UNITY is just the trading symbol for the SuperNET asset.

you can get a NXT wallet installed from nxt.org
then you will be all ready to withdraw into it. The SuperNET v1 wallet is about to go into a wider coverage beta release, but the NXT portion is compatible, so just make sure you dont lose the passphrase! The passphrase is your wallet and it will work for the NXT standard wallet and with SuperNET wallet

James

i'm looking for a quick walkthrough on how to withdraw UNITY from bter once i can ..


is it preferable to use the UNITY client or doesnt matter. i'd prefer to use something stable so i'm not fussed about any need to update.

The way InstantDEX API works is you ask for an orderbook, it shows all the orders from everyone. If you see an order you want to match, it will have the exact syntax needed for a "makeoffer" API. So copy it and submit it as an API call.

This will in turn generate a processutx API to send to the remote node

Which receives it and send back a respondtx API along with the signedtx bytes that can be pushed to the network.

Now this is without anything fancy and requires fill or kill exact match and still a lot of error handling to put around it, but the basic atomic exchange is working again. depending on how long the NXT takes to generate the tx, the exchange happens very quickly. In fact I saw one trade happen immediately as I pressed enter, but usually there is a few second pause for the NXT to generate the tx.

Also the trade is completed offchain and then pushed to the network and with both sides verifying the signatures and details, it is a matter of time before it will get confirmed(*). but until it is, it cant be re-traded.

You can see the matched transactions on the NXT mainnet: 9945291270561970098 and 4233802116116130288

(*) there is a small chance for some funny business by the block generator so if you are trading with that node, some precautions are needed. But this is a detail and just requires a bit of fine tuning to the basic mechanism, along with adding a small fee for matching trades.

finally found the bug for the make offer. much easier to debug freshly written code, remembering all the details from code last summer is taking a bit of time.

but I think I am close to getting a negotiated trade.

Then it is adding things like error checks, bullet proofing and things that wont really be externally visible. The first priority is to get the API to where the GUI can be tested in a full cycle usage

James

any NXT account will work. So it could be a secureae account or one you make local, mynxt.info also has webwallets.

James

NXT withdrawals still not working at bter
