Learn more about Atsign’s Key Technology Components.  

The Foundation

atProtocol – Open and patented network protocol which functions to transport data from Point A to Point B, (peer-2-peer), sans client-server middle point.

  • Empowers decentralized private networking and any method of encryption security.

For Building

SDKs – Software development kits to (1) build custom apps and connect devices using all the components of Atsign technology and (2) provides end-to-encryption layer to protect data in transit and at rest

  • Available versions: Stable: Dart/Flutter and Java; Beta: Python and MicroPython; Alpha: C, C++, Go, and Rust.
  • Convenient BSD3 Open Source License granting intellectual property right to the developer.

For Deploying

atSigns – Unique identifiers for people, entities, and things communicating via the atProtocol. They empower ownership and control over data, allowing fine-grained access management and personalized interactions.

  • For example, @alice, @acmecorp, @frontdoorcamera, @gateway

atServers – Secure, private data stores that manage communication and data access for atSigns without storing or decrypting personal information.

  • Hosting can be on the cloud, on prem, or air-gapped.

atDirectory – The only centralized Atsign technology component. The atDirectory is a service that stores the location of the atServer for each atSign. It works similar to DNS. Note: Support for federation is in the architecture and on our roadmap.

See our documentation for more detail.
