LegendaryActivity: 1008Merit: 1000 [PAID] Litecoin bounty [25 LTC] for porting brainwallet.org to litecoins April 05, 2013, 05:30:53 PM

Last edit: July 08, 2013, 05:22:14 AM by chriswilmer #1 EDIT: This thread was dormant for a long time so I unfunded the bounty address. I am still willing to give 25 LTC to someone who develops a brainwallet, but this is just a heads up that the bounty address is no longer in service.



EDIT2: Bounty paid! It's 90% there right now... I'm excited, harningt is working on getting it all the way there.



Hey Guys,



Willing to pay 25 LTC to the first person to port brainwallet.prg to litecoins. I am actually less interested in the brainwallet aspects and more interested in the ability to digitally sign offline transactions. If there was an interface to an electrum-style server where I can safely broadcast the transaction I will double the bounty (and use the said mechanism to send the litecoins).



25-50 litecoins is currently about $100-$200 USD... think about it!

Btw, this is how I created my bounty address. I sent the award by creating a fresh wallet.dat and importing the privkey with importprivkey. If I can make one suggestion, create an address for this bounty using https://github.com/weex/addrgen and post the address so a) the developer can see that the funds exist and b) others can add to the bounty. I'll add 10 ltc when it's up.Btw, this is how I created my bounty address. I sent the award by creating a fresh wallet.dat and importing the privkey with importprivkey.

If you need a signed message to prove that I control the address, I'll do it of course. I'm just running out the door right now and I don't want to figure out how to do it with Litecoin-qt at this moment.

I have put together a slightly modified version of bitcoinjs-lib (had to figure out how to compile the many many scripts together) to allow a default address-type to be configured... then I had to apply minor tweaks to brainwallet.org's code to use the new locations of things in bitcoinjs-lib + fix the default public address filled in the signing page.



NOTE: The transaction construction currently does not work due to it interacting w/ blockchain.info ... and clicking on addresses right now in the signature verification window points you to blockchain.info ... with a litecoin address... with no indication from them that all is wrong.

Funny discovery w/ this - nobody has paid into the "correct horse battery staple" wallets for Litecoin Got the blockchain.info usage fixed.. but transaction building is a no-go due to no existing web services for Litecoin getting transaction details... on the other hand, transaction signing w/ pre-created data will work just perfectly.Funny discovery w/ this - nobody has paid into the "correct horse battery staple" wallets for Litecoin

Hey harningt, I checked out your demo. It's great! (can I post a link to it?)



I just realized something... the interaction with blockchain.info isn't actually necessary for offline transaction signing. I realize the brainwallet.org utility tries to get that from blockchain.info, but if it fails, you can paste in the transaction history manually (this is actually how I do it, since my btc brainwallet.org website can't access blockchain.info anyway).



I will up the bounty to 40 LTC (and maybe weex will throw in another 10 if we ask him nicely) if you can add:



1) Manual adding of transaction histories to make offline transaction signing work

2) Tell me how I can generate a properly formatted transaction history using the litecoint-qt client (OR some other way)? [this is so that I can actually use this to do offline transaction signing]



If you think this can't be done for some reason, or just don't want. I'll send you 25 LTC anyway. Hey harningt, I checked out your demo. It's great!

Sure, here's the site for all to try



Currently the "Transaction" tab is removed since the behavior is quite hosed. Will be poking around litecoind commands to see about generating proper transaction data to sign. Looks like listunspent might be the right RPC / litecoind command... though it looks to only work w/ addresses w/ full private key... Will let you know of updates. Heh, was poking around the transaction management and had a transaction signed, but litecoind rejected (so will have to check out what's going on there)Sure, here's the site for all to try http://www.eharning.us/brainwallet-ltc Currently the "Transaction" tab is removed since the behavior is quite hosed.

Hey everyone, can we please have a round of applause for harningt? Also, if anyone else wants to add incentives for harningt to go the last mile, please post to this thread!

As an aside - you mentioned "Electrum style server" ... I have one I'm working on testing out right now in fact - your little fund will give me a chance to make sure transactions flow from an Electrum server to a slightly hacked electrum client - for which the server would be required for Litecoin support in my Bitcoinstarter - a little busy w/ side projects toward a common goal



Will let you know as soon as I get status on building proper input for the transaction system... in the mean time.. I suppose I can enable it for anybody wanting to play around.
