Snowflake is a system that allows users to circumvent web censorship by helping them access the Tor network through a network of volunteers who act as intermediaries by providing their own internet connection.
It works by connecting the volunteer with the person in need, creating an entry connection...
Basically, simulating a WebRTC call allows a user to access the Tor network in a country where connections are monitored.
Through NAT Traversal two users are brought into communication without opening any ports to the outside of the network
Humans need to stop naming things "Snowflake". We have too many. Perform an internet search with "snowflake SUFFIX", where SUFFIX is any other term, eg Crypto or Database or Movie, and you will get at least one hit.
