What is Decentralized Social Network?

A decentralized social network is an online platform that operates on blockchain technology or distributed servers, rather than centralized servers controlled by a single company. This architecture fundamentally changes how user data and content are managed, stored, and shared across the network.

In a decentralized social network, user information and content are distributed across multiple independent nodes or stored on a blockchain. This approach enhances privacy and security by eliminating a central point of control or vulnerability. Users have more ownership and control over their personal data, digital identity, and content, as there is no central authority that can unilaterally access, manipulate, or sell this information.

One of the key features of decentralized social networks is their resistance to censorship. Without a central authority to moderate or manipulate content, these platforms promote free speech and allow for more open expression. This characteristic is particularly valuable in regions where traditional social media may be subject to government censorship or control.

Examples of Decentralized Social Networks

Mastodon

Mastodon is one of the most recognized decentralized social networks. It operates on a federated system, consisting of multiple independently run servers called instances. Users can join or create their own instances, allowing them to control their environment and content moderation policies. Mastodon supports various media types and provides a microblogging experience similar to Twitter.

Nostr

Nostr is a decentralized platform that uses relays to transmit messages rather than hosting content on central servers. This architecture enhances privacy and security, ensuring data remains under user control. Nostr's open-source nature and resistance to censorship make it a compelling option for privacy-conscious users.

Lens Protocol

Lens Protocol is a blockchain-based social graph built on the Polygon network. It aims to create a decentralized social media environment where users own their content and connections.
