Topic:
"Bitcoin and Beyond," presented by Dr. Darren Tapp,  director of customer service for SnoopWall.

NOTE: This presentation will cover advanced topics (a "deep dive") in encryption techniques and protocols.

Description:
There are several cryptographic tools that are used to secure the Bitcoin protocol.
The most important of these tools is the Elliptic Curve Digital Signature
Algorithm, or ECDSA. In this presentation we will review this digital signature
algorithm including the group structure on elliptic curves and finite fields.  We will also review hash functions and how two specific hash functions are used
to secure Bitcoin in different ways.  We will then discuss known attacks
on ECDSA, and why a faulty random number generator on Android required the
immediate upgrade of some bitcoin software. We will speculate how bitcoin could
be upgraded in the event of a serious ECDSA attack.  If time permits, we will discuss market risks and rewards.

    I missed the meetup due to bad weather. Are there slides or other materials from the meetup that are posted?

    Dr. Tapp gave an excellent presentation. He explained technical aspects of Bitcoin that are in need of greater understanding. Thanks to Bradley for his organizational efforts in arranging this.
