Web3 Index

Loogo's Web3 layer is what no other search engine can replicate without owning a public blockchain: a Tantivy full-text index over EmpoorioChain state, .empoorio domains, and registered ecosystem dApps.

Indexed content

• Smart contract metadata and ABIs (public)
• .empoorio domain registrations
• dApp listings anchored on EmpoorioChain
• Public chain events relevant to discovery (no PII)

Architecture

Indexer (local)  →  Tantivy Index  →  Web3QueryService
                         ↑
              EmpoorioChain RPC / light client

• Web3QueryService serves queries from the local index
• P2P nodes announce "I have Web3 index available" on the Empoorio network
• No central server required for this layer

Trustless verification (Phase 3)

Before P2P goes to production, results must be verifiable against on-chain state:

• A malicious node injecting false dApp listings is rejected
• Verification runs before results reach the omnibox UI
• Rejection metrics tracked in loogo-status (internal)

This is Loogo's primary security differentiator versus centralized search APIs.

P2P query protocol

1. Client broadcasts query to available Web3 nodes
2. Nodes respond with Tantivy hits + Merkle proofs (roadmap)
3. Client verifies proofs against chain head
4. Merge layer ranks verified Web3 hits above clearnet when exact match

DMS incentives

Node operators who serve Web3 queries and pass verification consistently earn Dracma (DMS) rewards — same token as gas and ecosystem payments.
