Blockchains are global networks that can have millions of users, each adding information or data that is secured through cryptography.

A new cybersecurity system developed by researchers at the University of Waterloo has a set a new standard in the fight to protect people from malicious online attacks.   

The new tool, a naming system called Bitforest, is one of the first systems that provides an efficient method of decentralized, online security in a way that is easy for the average person to use. The naming system converts more easily remembered names, such as usernames and domain names, to values like public keys needed for securely communicating with computer services and devices.
