Open-Transactions is about an account system and related financial instruments. It is a library that allows to create a server which doesn't need to keep records of transactions, but works by signed agreements on the current account balance. The library also allows a client to communicate with the server. On top the core functionality other financial instruments are made possible: checques, electronic money etc.

BlindBitCoin is a very clever bridge between electronic money (which is all about anonymous transactions) and bitcoin (which is a transparent p2p accounting and transfer system for units of 'digital gold' ). You can exchange bitcoins at BlindBitCoin into blinded electronic cash, using a javascript client that runs in the browser. You will get a long url which you can send to somebody, who can then redeem the coins (using the javascript client again).
