==Darknet versus opennet==
As of version 0.7, Freenet supports both "darknet" and "opennet" connections.  Opennet connections are made automatically by nodes with opennet enabled, while darknet connections are manually established between users that know and trust each other.  Freenet developers describe the trust needed as "will not crack their Freenet node".<ref>{{cite web |url=https://d6.gnutella2.info/freenet/USK@sUm3oJISSEU4pl2Is9qa1eRoCLyz6r2LPkEqlXc3~oc,yBEbf-IJrcB8Pe~gAd53DEEHgbugUkFSHtzzLqnYlbs,AQACAAE/random_babcom/156/#Requiredtrustforformingadarknetconnection |title=Required trust for forming a darknet connection |website=random_babcom |access-date=29 November 2017 |archive-date=7 October 2015 |url-status=dead |archive-url=https://web.archive.org/web/20151007012112/https://d6.gnutella2.info/freenet/USK@sUm3oJISSEU4pl2Is9qa1eRoCLyz6r2LPkEqlXc3~oc,yBEbf-IJrcB8Pe~gAd53DEEHgbugUkFSHtzzLqnYlbs,AQACAAE/random_babcom/156/#Requiredtrustforformingadarknetconnection }}</ref> Opennet connections are easy to use, but darknet connections are more secure against attackers on the network, and can make it difficult for an attacker (such as an oppressive government) to even determine that a user is running Freenet in the first place.<ref>{{cite news|url=http://www.golem.de/0805/59592.html|title=Darknet-Fähigkeiten sollen Softwarenutzung verbergen|date=9 May 2008|access-date=29 November 2017|publisher=Golem|archive-date=5 October 2015|archive-url=https://web.archive.org/web/20151005070232/http://www.golem.de/0805/59592.html|url-status=live}}</ref>

The core innovation in Freenet 0.7 is to allow a globally scalable darknet, capable (at least in theory) of supporting millions of users.  Previous darknets, such as [[WASTE]], have been limited to relatively small disconnected networks.  The scalability of Freenet is made possible by the fact that human relationships tend to form small-world networks, a property that can be exploited to find short paths between any two people. The work is based on a speech given at [[DEF CON (convention)|DEF CON 13]] by [[Ian Clarke (computer scientist)|Ian Clarke]] and Swedish mathematician [[Oskar Sandberg]].  Furthermore, the routing algorithm is capable of routing over a mixture of opennet and darknet connections, allowing people who have only a few friends using the network to get the performance from having sufficient connections while still receiving some of the security benefits of darknet connections.  This also means that small darknets where some users also have opennet connections are fully integrated into the whole Freenet network, allowing all users access to all content, whether they run opennet, darknet, or a hybrid of the two, except for darknet pockets connected only by a single hybrid node.<ref name=Roos2014 />
