We just finished the first implementation of M of N oracles as explained in Orisi Whitepaper
http://github.com/orisi/wiki/wiki/Orisi-White-Paper and in Gavin's bit-thereum post:
http://gavintech.blogspot.com/2014/06/bit-thereum.htmlThe nodes' addresses and information is listed at
http://oracles.li/The oracles right now support just one command - a "timelock". It allows you to lock BTC funds on a multisig address for a period of time selected by you. The funds get unlocked only with both your signature, and signatures of above 51% of oracles you selected. Oracles will sign deliver their signatures once the time is up, and they have no way of running away with funds.
Here's the Orisi documentation
https://github.com/orisi/orisi/blob/master/INSTALL.md.
You can set up your own oracle server node, or you can launch a client and perform a basic timelock transaction.
Other transaction kinds are coming soon - next week we'll probably have transactions depending on Bitstamp's BTCUSD price, and a generic mediation module depending on a word appearing on an url address (similar to
http://earlytemple.com, but distributed)
