Intended to provide a base infrastructure for a decentralized internet, Swarm splits information up between the computers of different network participants.
To protect this layer from censorship – what Nagy defines as taking information out of circulation – decentralization and privacy are vital.
For example, what developers call “redundancy” is key to how Swarm protects against censorship. This refers to the duplication of critical system components of a system – creating, in effect, a “swarm” of machines.
