What is a DID?

A Decentralized Identifier (DID) is a globally unique identifier that you control, rather than a traditional account owned by a single company. In T3N, did:t3n: identifiers are used to represent users, agents, and other entities with cryptographic keys and permissions attached. For the formal specification, see the W3C standard Decentralized Identifiers (DIDs) v1.1.

​
How is my data kept private?

Your data is encrypted and only processed inside Trusted Execution Environments (TEEs). This means operators and infrastructure providers cannot see your raw data, even while it is being used by agents or APIs. For more on TEEs at the hardware level, see Intel® Trust Domain Extensions (Intel® TDX).

​
What is MCP?

The Model Context Protocol (MCP) is an open standard for connecting AI applications to external tools and data sources—think of it as a standardized way for agents to call APIs, databases, and workflows. You can read the official introduction at modelcontextprotocol.io.

What is an Agent?

An Agent is an AI-powered or automated service that can act on your behalf inside the T3N network. Agents only get access to data and actions that you explicitly authorize, and all activity is tied back to your DID.
