It's always great to have competition, as it makes products more perfect. From my side, I would happily agree to split the bounty between the developers of the most stable and easily usable wallets. There should be a voting at the 1st of July (?) of the best GUI, picked by the users.
The prizes could be the following ('x' is a variable which stands for the amount of the bounty, equally split into 8 parts):
1st place: 5 * x
2nd place: 2 * x
3rd place: 1 * x
Please give feedback about my idea!
Great suggestions. The terms will be a 5:2:1 bounty split to be decided on July 1st. We have 2610 XMR collected currently so that will be the prize pool (plus anything that may be contributed over June). The decision will be made by the bounty funders over an IRC discussion.
The end goal here is really to get something the community will use in the medium/long term, not just a coding contest that ends on July 1st. So the winning GUIs will be decided based both on the current state and on future viability as a cross-platform GUI. It's fine if a submission doesn't quite meet the second part - it's still eligible to receive part of the 5:2:1 prize pool.
