BitCoin Protocol Hackathon for non-currency Usage

This is a special meeting, and could be bit off topic. We will discuss some of the following. I am expecting some of you to contribute also. We would like to start to build some non-currency app if there is enough interest. 

• How to use Bitcoin Protocol to create new non-currency applications, and new kind of crypto contracts

• How to mine crypto?

Interesting links: Let's try to understand the following.. 

Some more links (Thanks to Justin D of BitDevNYC)

Core dev:

• Scripts, in depth 

• discussion: reusable addresses with identity based encryption

• Let's talk Bitcoin Adam Back interview (creator of HashCash, the inspiration for Bitcoin's POW) - committed tx, homomorphic value, fungibility, privacy

.9rc1 - open issues that need to be resolved before release

• Stealth addresses don't scale to SPV nodes. An alternative name, static.

• Bait for reusable addresses - help with SPV node privacy, a proposal

• BIP 0032 - HD Wallets, wiki rewrite (more readable)

• Ethereum - Comments and concerns

    Good to meet you all yesterday. For you Java programmers, Mike Hearn's `bitcoinj` might be a gentler way to grasp the technicalities of BTC. It's geared more toward creating thin-clients rather than mining. The documentation is very helpful, both the wiki pages and the Javadocs.

    I don't know if the format is to work in teams, but if anyone with an idea wants to get a head start, get in touch with me and maybe we can have some code working in advance. My experience with hackathons is that one day is barely enough time to settle on an idea, much less get a prototype working.

      Start by identifying the target merchants: do they (1) not accept Bitcoin and don't want to, or (2) not accept Bitcoin but want to start, or (3) already accept Bitcoin but want to do it better? The product will be different for each since (1) requires conversion to local fiat and hiding the customer's use of BTC from the merchant, (2) requires setting up the merchant's BTC infrastructure (and probably considerable education), and (3) requires improving whatever the merchant is already using.

      Thanks Adam for explaining it in detail. I would like to try my hands with option 2 first. It will definitely help me to understand Bitcoin technology better.
