Electronic cash has been the lynchpin of cypherpunk software goals for decades -- yet, there is no viable electronic cash system in the marketplace. We will describe the theory, applications, past attempts, politics, failures, and successes in the field. We present a specification and implementation of a new system which is secure, open, extensible, Free, and which will hopefully avoid the technical and strategy mistakes which plagued earlier systems. We will solicit developer involvement in creating applications which use this infrastructure. We hope this infrastructure is a first step toward limiting the power of governments and other oppressors vs. individuals and small groups throughout the world. It is also an example of how to proivide a critical infrastructure application, in an open-source form, in the post-dotcom world, and a generally-applicable demonstration of how security hardware and software can be used in applications to win user trust.
