setiQuest is a project that empowers earthlings everywhere to become active participants in the search for cosmic company. It includes two software systems. SonATA detects the evidence of extra-terrestrial technology in data that has been collected, and SetiQuest Explorer is an Android app through which anyone can access the same telescope data and visually detect evidence of alien technology.
The Open-Transactions project is a collaborative effort to develop a robust, commercial-grade, fully-featured, free-software toolkit implementing a full-strength financial cryptography library, API, CLI, and prototype server. Open-Transactions democratizes financial and monetary actions. You can use it for issuing currencies/stock, paying dividends, creating asset accounts, sending/receiving digital cash, writing/depositing cheques, cashier's cheques, creating basket currencies, trading on markets, scripting custom agreements, recurring payments, escrow, etc. Strong crypto is used. Balances are unchangeable (even by a malicious server). Receipts are destructible and redundant. The transactions are unforgeable. The cash is untraceable. The cheques are non-repudiable.
