And here is what we have been working on for the Miami show.....Yes, a Dash Instantx detecting, soda/pop machine. Why a vending machine? Because it shows off InstantX in a real use point of sale scenario. This can't be done with any Bitclone(coins that confirm and secure transactions at the same time). We have a machine(Thanks Camosoul), we are almost done with software(Thanks Moocowmoo), graphics are started(Thanks Raptor73), and will be adding android wallet instantx functionality(Thanks Fulltimegeek). Camosoul, Moocowmoo, Fulltimegeek, Splawik21, Oaxaca, Raptor73, and Solarminer(The Instigator) are all helping on this. What does it do?- Displays a QR code to send Dash.
- If the amount is sent via Instantx and the amount is equal or above the amount needed, it sends the command to credit the machine for 1 beverage. This is fast - Instant from a human's perspective.
- If the amount is less/over, it instantly returns the change.
- If a darksend transactions without exact amount is sent, it keeps the change.
- If a standard transaction is sent it rejects it and instantly sends it back. (Maybe display "We don't wait for block confirmations and either should you, InstantX instead!")
- Once a purchase is made, it displays a thank you and rotates the QR code.
This is just a stepping block. Next we plan to convert gas pumps, which is why returning change is important. And many other uses, only possible because of InstantX.

Wow! How cool is that to show off the power of DASH in a real life situation! Fantastic!

Wow, you thought I used Photoshop...Thanks. Only Powerpoint was used on that last pic. I figured my post would be tweeted, so I wanted to make it look closer to a finished product. We (as in Camosoul) have a lot of work to make it look like my last picture.

If a darksend transactions without exact amount is sent, it keeps the change.
I don't quite understand this bit. How can the receiving address know if it's a darksend transaction or not ? Darksend is a background mixing process, not a payment action. Surely, at the point of payment, there's no distinction

This is amazing Solarminer! Please excuse my curiosity, but what kind of hardware are you using to handle the Dash part? Raspberry?

I don't quite understand this bit. How can the receiving address know if it's a darksend transaction or not ? Darksend is a background mixing process, not a payment action. Surely, at the point of payment, there's no distinction Simple answer.When you send a payment there is a box for Instantx and for darksend. If you hit the darksend box - no change for you. If you don't send with instantx checked - Instant refund. Yes, you can tell looking at the incoming transaction how these were sent. More detailed answer.Do you remember that bit about darksend transactions being anonymous? Yeah, well it isn't possible to figure out where they come from(or more appropriately, which of the 100 inputs are the senders). There is also no change address to figure out a return address. A non-darksend transaction will always(I think) have a change address we can use to return funds. Moocowmoo made a script that can figure this out in a split second. Really cool.

Do you remember that bit about darksend transactions being anonymous? Yeah, well it isn't possible to figure out where they come from Solarminer, thanks for the explanation. I also think the vending machine idea is a great example of the power and versatility of instantly confirming crypto. It's a fantastic initiative. But I can see some banana skins that you might want to think about before rolling it out to a public demo. First of all, this: If a darksend transactions without exact amount is sent, it keeps the change. ...I don't think that's acceptable because it isn't commercially consistent and basically amounts to theft. Think two 13 year old teenage kids with iPhones who buy a coke. One gets change and one doesn't cos they're not technologically nerdy enough to check their denominations ? They don't really want to be faced with questions like "Darksend" "Not Darksend". It might as well be two different currencies. Further, if change is involved, it should be on condition of supply of a change address, not the on condition of coin denominations. That way the service can be commercially consistent and also optimally serve instances of homogeneous denominations as your current design does. (Because it supplies an implicit change address, but heterogeneous payments then need the option of supplying an explicit one). It depends on amount you send. Transaction comes from few addresses. Denominations like 0.1, 1.0, 10 are in different addresses.
I'd just ditch the whole idea of change since it isn't really compatible with cryptocurrency (other than change addresses in wallets where the wallet itself has full control over everything). Just accept exact amounts otherwise no coke - since it's far easier for a customer to type the right amount into their wallet than be worrying about how their payment was denominated. Doesn't the QR code do that for them anyway ? Sorry to be so nerdy about this but it's a great idea and I don't want you to get shot down by a*ssholes (other than me ) who home in on the glaring banana skins of the concept only to ignore the huge potential of it. Also, what you're demonstrating isn't really a vending machine, it's a metaphor for an entire commercial business model so it's the commercial priorities that need to be thought through, not the blockchain technicalities. In that regard, details like that change thing can explode in your face when presented to the "wrong" audience.

BTW am running my linux distros from live-usb. Anyone? Look like you are trying to install Electrum Dash Client on x86 (32 bit) live linux system. I think there are 2 options for you, 1. compile from source as instructed on your post. 2. try install on [x86_64/amd64/64 bit] live linux system if hardware support. Hope this help.

Nice comment by Pinkfish too. It's so well said - I can't resist of quoting it: Pinkfish:I'm back to investing in DASH. They have more a more inovated team than any other coin. New coins are distributed like this: 10% for core team to develop, 45% to masternodes which are people holding DASH and not spending it, and 45% to the miners.
That is brilliant and if Bitcoin did that the coin would be way way stronger than it is now. Miners have way too much power in Bitcoin. All new changes are made by Masternodes voting in Dash. That again is brilliant so all changes are made by the people actually invested in the coin.
The more I look at DASH the more I love it. With all that's going on right now, who can blame him? Only Powerpoint was used on that last pic. I figured my post would be tweeted, so I wanted to make it look closer to a finished product. How did you know that? https://twitter.com/taoofsatoshi/status/682014497062666240Honestly, I'm just blown away by this community. Officially and unofficially, we are killing it right now and it shows with the rising price and renewed interest. We all know what this community is capable of, and it frankly brings me joy to see everyone contributing in their own way. We have lots of work remaining, however, so keep up the pace...

Pille, All running on a little Raspberry Pi 2 ....with 5" display arriving soon. Yes, toknormal, from the machines perspective both DS and non-DS IX are the same. Darksent transactions have inputs we can send refunds/change to. The machine will return non-ix transactions back to the first input of the tx, same with IX (DS or no) underpays. Overpays get their change back. But, considering the qr code has the price embedded, this was more experimental than practical. The necessity of change from a vending machine is an artifact of fiat denominations that don't really apply anymore (tee hee).
