Insights on decentralized agent discovery, trust infrastructure, protocol interoperability, and building the open agentic web.
Building DNS for AI Agents: Our NANDA Index Implementation
AgentAddr records, Ed25519 signing, KV-cached resolution, and AgentFacts v2 — how we built a production-grade NANDA Index node.
The Protocol Bridge: Making Every Agent Discoverable
A2A agents can't see MCP agents. The NANDA Switchboard bridges them all — register once, discoverable everywhere.
Adaptive Resolution: Smart Routing for the Agentic Web
Three strategies, one answer — multi-strategy scored resolution with geo, trust, capability match, and health awareness.
CRDT Gossip: How NANDA Nodes Stay in Sync
LWW-Register CRDTs and gossip protocols for conflict-free registry federation — no consensus needed.
The Self-Improving Agent Stack
How CubiCube's 10 specialized agents are automatically discovered, certified, selected, and optimized — with no human in the loop.
From Web Pages to AI Agents: The Paradigm Shift
The internet was built for documents. AI agents need something fundamentally different — and NANDA is building it.
Why DNS Fails for AI Agents
DNS maps names to IP addresses. Agents need capability discovery, trust verification, and protocol negotiation — none of which DNS provides.
The Quilt Architecture: Decentralized Agent Discovery
How NANDA federates agent registries using push-based gossip synchronization — no central authority required.
NANDA, A2A, and MCP: Complementary Layers of the Agentic Stack
Three protocols, three problems. How NANDA Index, Google A2A, and Anthropic MCP fit together.
AgentFacts: Verifiable Credentials for AI Agents
W3C Verifiable Credentials meet AI — how AgentFacts bring cryptographic trust to agent metadata.
Privacy-Preserving Agent Discovery
NANDA's dual-path resolution architecture — balancing agent discoverability with privacy protection.
Zero Trust for AI Agents: The ZTAA Framework
Applying zero-trust principles to inter-agent communication — verify explicitly, least privilege, assume breach.
Developer API Keys for Decentralized Infrastructure
Designing parallel API key systems across KYM and NANDA — SHA-256 hashed storage, tiered rate limits, and Bearer auth.
Cross-Platform Trust Signals
How reputation data flows between KYM's trust registry and NANDA's discovery infrastructure for unified agent trust.
NEST Quickstart: Deploy Your First NANDA Agent
A hands-on tutorial for deploying and registering agents using the NANDA Sandbox and Testbed.
