Title: Bitcoin Hackathon (event), 13-15 July, IN-Berlin, Berlin Post by: kangasbros on June 14, 2012, 02:37:07 PM The Hackathon is over, thanks for everyone who participated in any way! Results etc below.
==== We previously had one Hackathon in Finland, and it was a success. Now we will have another in Berlin. Welcome! Hackathon - people gather together at one place, hacking, programming, brainstorming, developing and launching a product in one weekend! Meet other skillful technologists. Form teams. Share ideas. Execute. Gain fame & prizes by winning the competition. http://bitcoin-hackathon.com/index.php/Main_Page Facebook event: https://www.facebook.com/events/320236274729013/ Just turn up! :) Edit: and any ideas are welcome: just send me a message. Also if you want to sponsor the event in some way, contact me (for example, if you have a business you want to promote or something). Title: Re: Bitcoin Hackathon (event), 13-15 July, IN-Berlin, Berlin Post by: kangasbros on June 14, 2012, 04:11:55 PM Are you interested in promoting your company/product/web site to the hackers and other participants? You can sponsor the event!
We have 4 different sponsoring tiers: Tier 0 - Your logo on the web site - 10 BTC or equivalent competition prize Tier 1 - Your logo on the web site and also on the event - 20 BTC or equivalent competition prize Tier 1.5 - A leaflet or other promotional material given away in the goody bag for participants - 30 BTC or equivalent competition prize Tier 2 - Promotion of your company/product alongside the event - for example, the best project which utilizes your API gains a special prize - 60 BTC or equivalent competition prize http://bitcoin-hackathon.com/index.php/Sponsoring Title: Re: Bitcoin Hackathon (event), 13-15 July, IN-Berlin, Berlin Post by: kangasbros on June 18, 2012, 04:07:19 PM LocalBitcoins.com will be sponsoring the hackathon, so we will have at least free refreshments and some snack/food :) Maybe also the contest winner names will be forged in the block chain for eternity!
Also if you have any project ideas etc., you can discuss it here. I have been toying with an idea of a open source bitmit-style marketplace, so people can easily start their own bitcoin-based marketplaces. It would be a web app using django_bitcoin library. However I'm still pretty open about what I'm gonna do, if somebody wants to team up with me, just send me a msg. I can do python, django, iPhone dev, also php and even .NET (although I'm not very happy doing those) :D Title: Re: Bitcoin Hackathon (event), 13-15 July, IN-Berlin, Berlin Post by: genjix on June 27, 2012, 04:40:21 PM Attending:

1. Offline transactions for BitcoinJ/Android bitcoin wallet: Andreas Schildbach and grazcoin - Ability for Android Wallet to do offline transactions Title: Re: Bitcoin Hackathon (event), 13-15 July, IN-Berlin, Berlin Post by: Mike Hearn on July 17, 2012, 04:05:04 PM Offline transactions means, if the buyer is offline they can send the transaction via Bluetooth to the seller. The user experience is (when it works) invisible - the MAC address of the sellers Bluetooth adapter is included in the QRcode and then the client can connect to it when sending coins without peering or discovery. The receiving side can then put the tx on the network and see if it comes back, thus checking its validity.
We're also looking at maybe letting the receiving side keep the transaction around in the wallet so if both parties are offline but trust each other, they'll broadcast it later when they have internet access. We got pretty far, though the demo we tried to do was too flaky to really work. Once some bugs are fixed and a bit more code is written it should work pretty well, and the system can be a subject for potential BIP standardization.

I'm all for that (or a slightly more general) standard! That would really reduce those connectivity issues and it should work for Spinner and other apps where signing happens on the phone as well :) |
