Decentralized communication refers to a system where communication and information sharing is not reliant on a central authority, such as a government or corporation. Instead, communication is distributed across a network of users, with no single point of control or failure. This approach allows for more privacy, security, and resilience in the transmission of data, as well as greater autonomy for individuals in controlling their own communications. Decentralized communication systems often leverage blockchain technology and peer-to-peer networks to facilitate direct and secure communication between users. This research area is of increasing interest as concerns about censorship, surveillance, and data privacy grow in the digital age.
