Verification-First Agent Marketplace & Scoped Authority Registry for BNB Smart Chain

Executive Architectural Overview
Verification-first agent marketplace on BNB Smart Chain reading all ERC-8004 registered identities directly from chain. Audits 338,000+ minted agents, probes 14,800+ endpoints with p50/p95 latency logging, exposes the gap between self-declared active agents and callable APIs, models cryptographic blast-radius authority using Altana Keystore (EIP-7702), and executes escrow hires via APEX (ERC-8183).
Core Architectural Accomplishments
Deterministic Guarantees
Integrated System Components
ERC-8004 Multi-Protocol Registry
Indexes 338,000+ on-chain agents and probes 14,800+ endpoints with real-time percentile latency logging and state-transition tracking.
Cryptographic Blast-Radius Modeling
Leverages Altana Keystore (EIP-7702) to strictly decouple contract call target allowlists from spend caps with monotonic on-chain revocation.
APEX Escrow & Evaluator Routing
Integrates decentralized job escrow (ERC-8183) with EvaluatorRouter grading and Sybil-proof verified review anchoring.
Database Self-Healing & Cron Fleet Guard
Built gebo-guard: measures query latency and automatically sheds non-critical cron workers during traffic surges, eliminating aggregate cold timeouts.
Live Census Statistics Engine
Computes dynamic funnel stats via refresh_census_stats() over stored rows, preventing hardcoded or falsified agent counts.
