Here are some Bitcoin App Ideas I was kicking around during my Spring 2015 ‘funemployment’:

1. International donations — Kiva is one of my favorite apps for charitable donations.  I’d like to ability to make donations on my mobile phone, with bitcoin.
2. International Remittence — This just seems like such an obvious use case for bitcoin, but I’ve never heard of anyone actually using the BlockChain for this.  An app that allows folks to send money back to family in another country with minimal fees and minimal technical know-how required would be a killer app.
3. Pay for computational resources  — It’s 2015 and the debate about net neutrality is still raging.  I wonder if, as the internet of things comes to fruition and we move from IPv4 to IPv6, there might be an opportunity for a a network protocol built on top of IPv6 that negotiates fundamental computation resources like bandwidth or cpu.
4. Monetize BitTorrent torrents — Content creators need to get paid, if each bittorrent torrent had embedded in it an address which users could ‘tip’ the creator, I wonder how the revenue would compare to a pay-to-download model.
5. Banking Systems — I used to work in Corporate Amurrica!, the systems that we used for transactions were several decades old.  I’d like to see the *BlockChain* used to power some finance applications.
6. New Incentives in Social Software — So many websites are ad-supported, I wonder if there is an alternative model where tipping or making micro-payments can replace ad revenue.
7. Decentralized markets — This one is mostly because I’m hoping that a solid competitor to eBay, and it’s clunky user experience and egregious fees, will come along one day.  Is there an opportunity to buy/sell physical goods over the internet without paying a middle man more than 0.1% of the transaction price?
8. Ephemeral Bitcoin Credit Cards — I think an app that allowed me to create a one-off credit card number, funded with a fixed amount of bitcoin, would be really useful.  It beats having to cancel your credit card every few months because your one-and-only card number was comprimised.
