II. Product Architecture

To ensure both feasibility and scalability, the system architecture consists of five layers: Interface, Agent, Evaluation & Incentives, Knowledge Storage & Retrieval, and Risk & Governance.

2.1 Interface Layer • Web/H5 Client: Public question stream, question details, answers and ratings, personal dashboard, leaderboards. • Identity & Session: Supports email/social login + wallet (EVM/BSC, etc.); anonymity and pseudonymity coexist. • Observability: Input restrictions (length/frequency), real-time feedback, shareable Q&A cards.

2.2 Agent Layer • Core Agent: LLM orchestration + configurable personality/system prompts (e.g., mood and daily theme). • Context Management: Global recent question stream summaries + user history retrieval (via embeddings). • Safety Guardrails: Prompt injection defense, sensitive content filtering, and supervised output checks.

2.3 Evaluation & Incentives Layer • PoQ Consensus: Agent network evaluates question quality and records value proofs on-chain. • Smart Contract Distribution: Rewards issued transparently and automatically. • Q-Score (Question Quality Score): • Novelty (semantic originality / de-duplication) • Depth (reasoning, density, inspiration) • Impact (engagement, citation, secondary spread) • Mood/Theme Weights (contextual amplifiers) • Formula: Q = w₁·Novelty + w₂·Depth + w₃·Impact + ξ(Mood, Theme) • Reward Engine: IQ Credits issued when Q ≥ threshold; daily quotas and decay curves configurable. • Social Weighting: Community likes, saves, and citations counted as secondary impact signals with caps to prevent manipulation.

2.4 Knowledge Archive Layer • Hot Data: Questions, answers, ratings, and social signals stored in databases/object storage + vector index. • Permanent Storage: High-quality Q&As stored on decentralized networks (e.g., Arweave/IPFS) to form a verifiable, global wisdom archive. • Open APIs: Enable third-party applications to retrieve and build upon Q&A data. • On-Chain Settlement: • Off-chain accrual, on-chain claims via periodic Merkle tree proofs. • Smart contracts: CreditsDistributor (whitelist + rate limits), Registry (version & policy management).

2.5 Risk & Governance Layer • Anti-Abuse: Semantic de-duplication, rate limits, device/wallet fingerprinting, reputation scores, blacklist/greylist. • Sybil Resistance: Multi-signal fusion (email/social/wallet + light human verification). • Review & Appeal: Anomaly re-evaluation, user appeals, audit logging. • Transparency: Scoring factors and weight ranges made public; version and parameter changes recorded on-chain (Phase III).
