Financial technology is about to enter a new phase thanks to distributed open source systems. The Ripple protocol, a virtual currency and distributed open source payment network, is a distributed global ledger that solves the double spend problem through a process of consensus rather than mining. Ripple replicates the key benefit of the earlier Bitcoin, a decentralized fixed amount currency that can’t be debased. Ripple furthers the Bitcoin mission with a new architecture that results in fast transactions (confirmations in seconds not minutes) and a multi-currency design that provides the world’s first distributed currency exchange.

OpenCoin co-founder Chris Larsen will sketch out the emerging technology from which first Bitcoin and then Ripple emerged.

    Chris just sent us a link to the video,

    It says free, but is the $145 ETSig SignUp charge a "cover" to attend this event?

      $145 is ET-sig parent org SVForum first-year membership. Members always get in free. This week non-members get in free to ET-sig, too.

I'm surprised by the level of growth I've seen since becoming an organizer, it's given me more confidence in my abilities.
