DSNP stands for Decentralized Social Networking Protocol, which is an open protocol and potential standard for social networking and social media. It is not owned or controlled by any one person or company, allowing anyone to build on it or use it. DSNP is stewarded by Project Liberty Institute, a 501(c)(3).

DSNP is an open-source social media protocol designed to decentralize data ownership, allow easier cross-platform interaction, and let users regain control over their personal data. This includes posts, connections, and messages. The decentralized approach allows users to retain ownership of their information and move it between platforms without relying on a single provider.

The AT Protocol (Authenticated Transfer Protocol, or atproto) is a standard for public conversation and an open-source framework for building social apps.

It creates a standard format for user identity, follows, and data on social apps, allowing apps to interoperate and users to move across them freely. It is a federated network with account portability.

ActivityPub is a protocol and open standard for decentralized social networking. It provides a client-to-server (C2S) API for creating and modifying content, as well as a federated server-to-server (S2S) protocol for delivering notifications and content to other servers.

ActivityPub has become the main standard used in the fediverse, a popular network used for social networking that consists of software such as Mastodon, Pixelfed and PeerTube.

Frequency is a blockchain designed to support decentralized social networks to give people control over their online presence. With Frequency, users can freely choose and connect on social apps while retaining ownership of their data.

Built on the Decentralized Social Networking Protocol (DSNP), Frequency offers scalable tools for message discovery, flexible storage for social and identity data, and a unique cost-sharing model that allows apps to deliver smooth, secure experiences that put users in charge.
