Dub is a lightweight Digitalcoin client based upon MultiBit. Dub stands for Digitalcoin Hub (more on that later) I initally got the idea for it a while before I began work on Coinmart. When I was not working on Coinmart I continued my work on Dub as a side project.

Here are some quick facts:

• Dub is the first lightweight wallet that supports a cryptocurrency other than Bitcoin.
• No other cryptocurrency, not even Litecoin, has a lightweight wallet
• The platform which it runs on, digitalcoinj, is only the third Java implementation of a cryptocurrency's protocol after Bitcoin and Litecoin

If you find any bugs or errors let me know


digitalcoinj

digitalcoinj is a Java implementation of the Digitalcoin protocol which allows it to maintain a wallet and send/receive transactions without needing a local copy of the official implementation. digitalcoinj is a port of litecoinj and bitcoinj to work with the Digitalcoin protocol. You can find the source code for digitalcoinj here : https://github.com/ShimalH/digitalcoinj

More Info

Coinmart will be integrated with Dub allowing you purchase items directly from your wallet. We have pushed Coinmart's launch date to 1 March to facilitate this feature
There currently is a 0.3% transaction fee. This will only be active for the next few months while we work on new features for Dub
I have contracted another external developer to help me work on Dub while the rest of the development team work on Coinmart.


Future Features

I mentioned earlier that I wanted Dub to be more of a Digitalcoin Hub rather than just a wallet. These are just some of the features which we hope to add to Dub in the near future to make it more of a hub.

Decentralized Exchange - This is a big one, we are currently in the concept phase. One of the big problems with the concept of a decentralized exchange has been how to track wheter a user has completed the transfer of a fiat currency. We believed we've solved that problem by proposing to integrate a payment gateway directly into each Dub client. The only problem is that we would have to develop the payment gateway ourselves which will be a very time consuming task.

Lotto - Another feature in the concept phase. I'm sure many if not all of you have taken the lotto at some point. Well if you can do it with USD or any other fiat currency why not with Digitalcoin? Users would pay an amount around 50 DGC for an e-ticket. The 50 DGC will then be added to a decentralized jackpot (small sums of Digitalcoins will be distributed out to each client, but will be inaccessible by the users themselves) Your chances of winning increases with the number of e-tickets you've bought. A winner will be picked at random by the system and will win the jackpot.

Integrated P2P Pool & Mining This feature has been requested a lot. GUIminer-Scrypt will be integrated into Dub along with a P2P pool. The Pool would be integrated directly into Dub meaning that rewards would show up automatically in the user's wallet.

hey baritus, i only have one question. will this work on a machine without java installed? I love the design, its nice and clean and is a refreshing contrast to the plain gray look of a windows qt.

Dub requires Java to be installed for it to work, however if the installer detects that Java is not installed it will give you the option to download it.

ah, i was afraid that was the case. Good work on this, and i will not insult your work at all, but i will not be installing or using this for the simple reason alone that it requires installation of java :( . there is just something about the invasiveness of Oracle that annoys me to no end, and i refuse to install/download their products.

perhaps you might find a way to package this software with a jre in a future update. then i'd be very interested, and i'm sure i'm not the only one who feels this way. i'll give you props though, atleast you aren't just distributing a jar like some people i know *cough cough* emunie

Small article for this project!

Another amazing digitalcoin project finished with success. Great, thanks for making this! :)

ShimalH really did some incredible work with this client. From both a design and functionality perspective it blows every other alt-coin client I've seen out of the water. The DGC blockchain loads in a fraction of the time of the "full" client, and I really like the ability to load multiple wallet.dat's into the client. Without a doubt this will be my primary DGC client from here on out.

Thanks for all your hard work, this is truly a game-changer for DGC!

Wow,  guess I'll have to try it out then!

i wish someone would release a version with the Java Runtime Env. packeaged in the executable. that would be awesome.

I'm will be releasing a new version this Saturday with the Java Runtime Environment packaged with the .exe file

You are awesome! got a donation address(BTC)??

This is my BTC Address : 1AQfZMMgFB5wwmFSYP4CwWMvyTvHa4WPeH  :) Just take a look on the Digitalcoin Forums (or in this thread) on Saturday evening for the updated version.

Baritus = Satoshi (although I don't expect a disappearing act)
Shimal = Gavin
DGC = BTC

really cool, nice interface as as well.

My new main client. Thank you! Very easy and stylish

It is a fantastic project and I think it really marks another milestone for DGC.
I have found a few display bugs on my Mac, but as this is still a very early version I am very positive that those will be cleaned out at some point. Will wait for the update on Saturday and then check again. :)

So what else do you have on the back-burner for us Shimal? :)

Stay tuned there's lots more to come

A proper website for Dub will be put up soon

Excellent work Shimal. Just another reason why DGC is bringing real usable services to help it grow and stand out in a crowd overblown with a large number of useless pump and dumps coins. I hope more people start taking DGC seriously because it IS going places. Its a privilege to have you helping our DGC community and I look forward to your next project.  :)

Good work here. DGC FTW ! This is what crypto-currency is all about.

Good job, ShimaIH. ;D
I have the same language display problem (jp).

Update 0.1.1 which releases this Saturday fixes this problem

Linux .desktop

you forgot

Hi all

I've relesed v0.1.1 of Dub. This version is mainly for bug fixes. We are still working on more features which include an Integrated Miner and P2P pool so stay tuned

Changelog

• Minor UI Tweaks
• Fixed Currency Ticker
• Fixed Language Issues
• Added an automatic updater to Dub

Nice work. Looking forward to seeing what further enhancements and improvements you have in store for it!  :)

norti, could you PM me with the details of your display bugs please.

still waiting on that JRE update  ;D

JRE bundling is not supported by IzPack installer, we have plans to move to another installer within the next 2 updates of Dub. Initially we were supposed to include JRE bundling in v0.1.1 however it was taking up too much time and a few issues needed to be addressed urgently in the update.

Just an update we are planning to hire an additional developer in the next few days to work on Dub.

@BitcoinFX

Sorry to hijack the thread. I'm still kicking myself for ignoring bitcoin when it started. How often did the original bitcoin faucet pay out?

Someone said it used to pay out 5 bitcoins a time. Is this right and what year was that if it is?

thanks,

it was great.

I like DGC more every day.

looks great, any status update on the future features listed

Does this need upgrading if the regular qt wallet is upgraded.

Also, someone said these lightweight wallets automatically detect the longest blockchain, so there is no need to upgrade after a hard fork. Is this correct?

this is a good question.. I wouldn't think so since as you said, it only reads the current blockchain, it doesn't do any work/mining to it. I'm afraid the only way to get a surefire answer is to try it yourself; I'm going to try this too with the android wallet (http://digitalcoin.co/forums/index.php?topic=964.msg6769#msg6769) so I can know for future reference. We've got a new update coming out in the next few weeks (http://digitalcoin.co/forums/index.php/topic,965.0.html) so we'll know soon enough.

EDIT: Actually yes, after asking baritus the light wallet will need to be updated any time the blockchain goes through a hardfork. I guess we need to hear from hashengineering and shimal in regards to the android wallet/dub respectively.

Have there been any hardforks recently, or are any coming up in the near future?

Soon there will be a hard fork.
