Is it possible? Yes. Using the RPi example, you would need to add an NFC hat (https://www.amazon.com/Raspberry-Interface-Communication-Supports-Provided/dp/B07WHGFN6Z), and write your own mobile wallet (for android and iOS) that leverages the phone's NFC hardware. The RPi would send the invoice data and the vendor's wallet address to the mobile device, and the mobile App would read that from the phone's NFC interface and create the blockchain transaction using tokens from the in app wallet. The example in my post above would be open/off the shelf, whereas this example would be proprietary/custom development.
So what you need is a non-custodial wallet - the one I linked is that. There are others too. On Android, langerhans' wallet is completely free of any corporate infrastructure in the middle and last time I checked someone here was working on a new iOS wallet - though I have not received the launch party invite to date, so I'm not sure where they're at with that.
If you can't remember the password used to encrypt it you can always try cracking it with hashcat. The process may not be successful depending on your hardware's power and how complex your password was.
Hi guys, Bobby from CoinGecko here. Yes we do value new commits in the last 4 weeks pretty highly. Dogecoin is still doing well so nothing much to worry here. The dev score will increase automatically when the devs commit again in the coming weeks :)
To add to this, I recently discovered this little gem: https://bitcoin.org/en/developer-reference. To think I'd been using the old Bitcoin wiki reference this whole time. Guide shows how to play with the full API in regtest mode which lets you do anything you could normally do, but no risk of spending real money.
I can give you a bit of guidance on this if you'd like. Firstly, I think you'll struggle to find DOGE to USD, I did at least. I took the route of DOGE to BTC to USD seeing as I already had DOGE to BTC down.
Here's a basic prototype of DOGE to BTC using jQuery, from this you may be able to make a start and add USD conversion, polling and such.
JS:
// cryptsy's public API for DOGE var apiUrl = 'http%3A%2F%2Fpubapi.cryptsy.com%2Fapi.php%3Fmethod%3Dsinglemarketdata%26marketid%3D132';
// node cross domain proxy server var jsonPWrapper = 'https://jsonp.nodejitsu.com/?callback=?&url=';
$.getJSON(jsonPWrapper + apiUrl, function(data){ $("div.price").html(data.return.markets.DOGE.lasttradeprice); });
HTML:
<div class="price">Loading...</div>
Here it is in action. If you'd like some more information or guidance on anything else let me know.
I use ProtonVPN when I'm doing testing (because spotting the 1-2 0.21 nodes on the network is a good way to figure my IP address), and sadly I don't think you can accept incoming connections over ProtonVPN. If anyone does have a solution though that would be brilliant.
If it's the doge android app, try to install it again and import the keys. I used the app in 2014 (don't think it was there in 2013).

If it asks for a password, then... well... you're screwed.
> you just scan a 2D code and money is transferred.
I built that demo using mid-2014 Dogecoin tech we formalized in 1.7... Doesn't need a government-approved & monitored "neo-bank" like Alipay or WeChat pay or the EU's "instant pay" schemes.
I'll try to make time to do another demo when we get the payment channels a bit more standardized.
Is that what you're looking for?
Okay... you've been incredibly helpful. Check it out -- the transaction is still there stuck in the Mempool thing -- https://blockchair.com/dogecoin/transaction/02b04543b0718ba70eb65cf2d6422430e97326b0b3024cf7f914d51ce480fb3d
Honestly I don't know, and also it's complicated. Dogecoin is merge-mined with Litecoin, so it's using mining work which would mostly happen anyway as part of the Litecoin block production.
The network hash rate is around 325Th/s (https://blockchair.com/dogecoin), Dogecoin uses Scrypt (so you need to compare Scrypt miners, which are different to Bitcoin's SHA256 miners), but work out how many miners that means and their power consumption, and it gives you a good estimate of what the two currencies together consume, though. I mean highly approximate but will give you an idea.
Please don't post binaries that you don't publish source code for.
I'd recommend everyone to follow the advice from nicehash on this. https://www.nicehash.com/blog/post/stop-using-phoenix-miner-immediately.
No one is stopping you from managing (this is just another name for mining) a node, it's just whether it will be profitable, a lot of hardware isn't up to standard to hash efficiently at current difficulty to reward ratio. What you can do is be part of a mining pool that distributes coins dependent on your contribution to the overall hashpower of a pool. Have a look at https://www.cryptocompare.com/mining/calculator/ltc?HashingPower=504&HashingUnit=MH%2Fs&PowerConsumption=1000&CostPerkWh=0.12&MiningPoolFee=1
Doge emissions eventually reach a trivial value too, I am not sure how different the time frame is, but ultimately it has the same issue.
This is the only chart I could find for dogecoin emission, and I'm not sure how accurate it is, but it appears that dogecoin will reach a trivial point of emissions long before Dash will. The fact that it's emissions are technically unlimited isn't really relevant to the issue.
The bottom line is that IF monetary inflation is needed to sustain these networks something will have to be adjusted at some point.

That seems like one too many steps through, I'd add a little help icon next to the button that users can click to launch a modal explaining it all.
Would be easy to set it up that way in a template so you could drop it anywhere (if you're using something like Angular or Backbone).
Here's a quick little example of what I mean (minus the modal, but you get the picture). http://jsfiddle.net/fjr4rtm7/
>What I am really thinking about is some kind of remote blockchain so one does not have the hassle to maintain their own dogecoind.
This is largely what SPV does, only with a more secure "light" wallet. See MultiDoge. It uses a wallet in what is conceived to be the most secure way possible, while having a less secure centralized blockchain source. Dogecoin is short on light wallets and really could use one for Android in my opinion.
>I am still trying to figure out what exactly would be unique with that kind of service that it does not exist yet.
That was my explanation of what seems to be the service you are thinking about. I know several projects, across many coins, are struggling to pay nearly $10 per month on a virtual private server to just to run a backend wallet listening for remote RPC commands. It seems a service could specialize in hosting wallets and save on costs by having many segregated instances of each coin for subscribed users and devising a way to share a single copy of the block chain for each coin.
Feel free to hit me up with questions all you'd like. I'm also on Freenode #dogecoin most of the time.
>It would be nice if I can exchange one crypto coin directly to Doge without going to an exchange.
Search DEXs there many getting built also there is Atomic swaps which allow for coins to be swapped without , current popular service is changelly
>There is also this whole NFT thing that is catching on with other cryptos.
Not needed, it is useless bells and whistles not required for a currency. We do not want to turn dogecoin into a jack of all trades. There are enough other cryptoscoins that are built for NFTs, dogecoin is a currency. All you need to do is 'get it, spend it', that is it not complicated.
>Then there is the steady creation of new Dogecoin every year. It might help increase the value if there was some feed back function in how many new Dogecoin can get created.
It is not important to increase the value of dogecoin, because dogecoin is a currency what is more important is to keep it steady with much less volatility. That is what is important for a currency.
Speculative action is detrimental for a currency, again all we need to do is 'get it, spend it'.
Have you tried downloading the newest wallet from dogecoin.com?
I had the same problem some days ago. Just tried now, and it works after downloading the newest version from the site :)
Hey pal. The wallet app worked on Windows XP? Wow, I am surprised!
Just so you can keep the spirit, here are some dogecoins to get you over the hump.
~~+/u/dogetipbot 20~~ didn't work
You are running Windows 7? And you downloaded from http://dogecoin.com/? That sounds right . . .
Coinbase do this in the way you suggest - https://coinbase.com/docs/merchant_tools/recurring_payments, but I can't help feeling there is a better way than having to trust 3rd party payment processors. I am going to try harder to find what the bitcoin people have proposed.
Agreed. You can't debit a user wallet from their side, but maybe a payment plan (as you've described) that's similar to how https://www.digitalocean.com/ handles payments (i.e. add money to your account, and just bill that account for their usage) would make the most sense here.
In other words, you could set up a payment system similar to DogeAPI's example, but change the "stuff to ship item goes here" part to "add money to user's account here". Then you can bill based on how much doge that's left in their account, and go from there.
Hi there Nexuist,
I made a Prestashop module which checks your site for the latest market price of Doge.
Is it ok if it does? I want to improve it to avoid spamming your site as much as possible.
The URL is this: http://www.prestashop.com/forums/topic/309565-module-cryptocurrency-accept-payments-in-bitcoins-litecoins-dogecoins-etc/
Thanks in advance :)
Maybe my request sounded a little blunt.
If so, it wasn't intentionally.
Someone posted a submission request over at fdroid
https://f-droid.org/forums/topic/dogecoin-wallet/
Maybe it can be sped up with support by the developer. Any help from /u/langerhans would be much appreciated.
Thanks
I suggest working away from Java into a more modern technology, like HTML5. There's actually a great HTML5 game framework that was released not too long ago called phaser. It allows you to make HTML5 games (compatible on both mobile/tablets and desktop) using TypeScript or JavaScript.
Now-a-days people aren't looking to enable Java for just anything because of Java's security and the threat of Java drive-by attacks. In a community built around money, attacks like that are prevalent.
If i put the regular expressions I try to use in my website they work but in my website they dont :(
EDIT: I'm using javascript and foundation 5. example
GREAT idea! I added that in, and I truncated the number of DOGE that each gift card costs to a whole number. There is no need for me to be receiving fractions of a dog at their current prices.
You can check out my plnkr thing here.
Now I am just trying to figure out a way to have the user to enter any value of gift card in a text box, automatically calculate the total cost in DOGE, then enter their payment address, name and hit purchase. Hopefully have something soon :)
I forked a node.js bitcoin client so we can have our own version, if you prefer :) The differences are primarily aesthetic for now but I think it will make it move obvious for Node.js devs how to get started!
/r/rnicoll already said it, just show up. Dogecoin is pretty much developed by anyone who cares about a change. Some become regulars, some come and go. 1.6 was mainly pushed forwards by /u/lleti and /u/rog1121, 1.7 is mainly being developed by /u/rnicoll, /u/langer_hans and me so far.
We tend to be in #dogecoin-dev on Freenode, especially between 5pm and 1am UTC. There's a dogecoin-development mailing list that's so new that nobody has used it yet. You can always just submit code on [Github](github.com/dogecoin/dogecoin), right now against the 1.7-dev branch.
I got the paid version of ProtonVPN because it allows for P2P and I wanted to use it for the node. It will definitely allow incoming and outgoing connections with Core. It tends to just takes a few minutes longer than usual for them to connect and stay connected though.
Incoming will only use my actual ip address rather than the VPN. However, outgoing connections will use the VPN ip most of the time.
I find it strange that the app is able to decide which connections to route through the VPN and which to go around the VPN. I was under the assumption that a VPN is supposed to take all data through it, not just some of the data lol
I'm no cyber security expert, I'd just rather not be advertising to the world that my ip has open ports, if possible.
I'll keep playing around with it and see if I can figure out a way to force it to go through the VPN all of the time. Maybe ill shoot Proton an email for advice.
I'll keep you posted. Thanks.
