# CEDAR
CEDAR is the CASS Ethereum Distributed Application Registry, and is composed of website code hosted on GitHub and a Smart Contract hosted on the Ethereum Blockchain.
The purpose of CEDAR is to provide a means of registering records at URLs (learner, learning, and non-learner), creating a validatable chain of ownership to a domain name, and enabling specific queries including getting all registered records for a learner, getting all registered records made by one party, and getting the registered record for a URL
