Overview of Omniledger
|
The DEDIS team is working on projects related to large-scale collective authorities (cothorities), which distribute trust among a number of independent parties to allow scalable self-organizing communities.
With no single trusted party, cothorities can secure software updates, provide public randomness, enable privacy-conscious medical-data sharing and a lot more.
Other projects include communicating securely over insecure channels and fast, scalable, accountable anonymous communication.
