Add AgentField - DID/VC identity infrastructure for AI agents

[santoshkumarradha]

Adding AgentField as a novel application of self-sovereign identity to autonomous AI systems.

What is AgentField?
Open-source infrastructure for AI backends that implements W3C DIDs and Verifiable Credentials as core identity infrastructure. Every agent gets a cryptographic identity; every action is signed and auditable.

Why it belongs in this list:
This represents a new frontier for SSI—extending decentralized identity from humans to autonomous AI systems.

Traditional IAM (API keys, OAuth) assumes predictable client behavior. Autonomous agents operate differently: they reason, delegate, and make decisions based on context that didn't exist when tokens were issued. Current systems can't answer: "Who did this, and were they authorized?"

How AgentField uses SSI:

• DIDs (did:key): Cryptographic identity for every agent, verifiable without network lookups
• Verifiable Credentials: Scoped permissions that travel with requests; automatic scope attenuation through delegation chains
• Cross-org collaboration: Agents exchange DIDs, present credentials, verify signatures—no shared IdP required

The positioning: "From 'trust us' to cryptographic accountability."
