Adaptive Proof Engine** (`skill/adaptive-proof-engine.md`) +Every DePIN picks one proof at genesis — this is wrong. A sparse cell with 2 nodes needs simple heartbeat. A dense cell with 50 nodes needs VRF challenge so attackers can't target a predictable mechanism. This meta-layer switches automatically based on H3 cell density, with a full Anchor program + TypeScript SDK that builds the correct proof payload for whichever strategy is currently active. Geographic distribution emerges from the economics: sparse cells have easy proof → attract operators → density rises → proof upgrades. + +**2. Coverage Insurance Protocol** (`skill/coverage-insurance.md`) +The question every enterprise data buyer asks: "What happens when you miss SLA?" The only honest answer is parametric insurance. Operators pay premiums automatically (deducted from rewards). When measured cell uptime falls below the contracted threshold, payout fires automatically — no claims process, no adjuster. Payout scales with severity: 1% shortfall = 10% payout, 10% shortfall = 150% payout. Transforms DePIN from best-effort to bankable enterprise SLA. + +**3. Node Reputation System** (`skill/node-reputation-system.md`) +Binary active/inactive catches Sybil after it's already draining rewards. A sliding-window Bayesian score (0–10K) detects degrading nodes before they fail. Confidence grows with observation history — a new node adapts fast (easy to build rep), a mature node is stable (hard to game with one good epoch). Five tiers drive 0.5×–3× reward multipliers. Score feeds into data marketplace access and insurance premiums — reputation becomes the operator's equity. + +**4. Data Pricing Oracle** (`skill/data-pricing-oracle.md`) +Fixed price set at launch is always wrong. Sparse network → data scarce → underpriced → protocol undersells. Dense network → data abundant → overpriced → buyers route around it. This on-chain bonding curve adjusts price every epoch: utilization above 75% target → price rises; below → price falls; within 0.5% band → no change (prevents oscillation). Quality-weighted supply prevents low-reputation nodes from inflating supply and depressing prices. Buyer forecast API tells buyers whether to purchase now or wait. + +**5. Hardware supply chain + secure element attestation** (`skill/hardware-supply-chain.md`) +Private key never leaves the ATECC608A chip. Counterfeit hardware physically cannot produce a valid SE signature. Includes manufacturing attestation flow, OTA firmware update security, export controls checklist, and the specific CE/RED technical file requirements most hardware teams discover 3 months too late. + +**6. RF regulatory compliance** (`skill/regulatory-rf-compliance.md`) +8-jurisdiction frequency matrix (US/EU/UK/AU/JP/BR/IN/KR) with exact power limits, dwell times, and channel plans. The 915 MHz vs 868 MHz incompatibility trap that kills cross-border DePIN rollouts. FCC Part 15 certification timeline (8–15 weeks, $9K–38K) with exact step sequence. On-chain compliance enforcement: nodes that don't register their certified frequency plan cannot submit proofs. + +**7. Death-spiral early warning** (`skill/depin-tokenomics.md`) +Typed `assessSpiralRisk()` monitors burn/emit ratio, weekly node churn, operator payback period, and price drawdown simultaneously. When 2+ conditions breach simultaneously → SPIRAL state → automatic escalation to treasury intervention, emission pause, and emergency DAO vote. Based on the actual failure pattern observed across sub-scale DePINs. + +**8. Wallet-grade security across the entire skill** (`skill/depin-wallet-security.md`) +A1–A8 threat model: RPC attacker, clipboard hijacker, address poisoner, supply chain attacker, and four more. Argon2id for all password derivation. HD gap limit discovery prevents fund loss on seed phrase restoration. Transaction intent verification hard-blocks unauthorized `SetAuthority` instructions before any signature is provided. + +--- + +## Who Uses Which File + +| You want to... | Load this | +|---|---| +| Design a new DePIN from scratch | `agents/depin-architect.md` | +| Model operator ROI before building | `commands/node-economics.md` | +| Build a Proof of Coverage system | `skill/coverage-verification.md` | +| Handle 100K+ device accounts cheaply | `skill/zk-compression.md` | +| Design token economics | `skill/depin-tokenomics.md` | +| Integrate Switchboard or a custom oracle | `skill/oracle-integration.md` | +| Set up hardware identity / anti-Sybil | `skill/hardware-supply-chain.md` | +| Navigate FCC/CE RF compliance | `skill/regulatory-rf-compliance.md` | +| Audit an existing DePIN protocol | `commands/depin-audit.md` | +| Respond to a rogue node cluster | `runbooks/rogue-node-detected.md` | +| Auto-switch proof as network scales | `skill/adaptive-proof-engine.md` | +| Price data dynamically | `skill/data-pricing-oracle.md` | +| Offer enterprise SLA guarantees | `skill/coverage-insurance.md` | +| Score and tier node operators | `skill/node-reputation-system.md` | +| Write operator documentation | `agents/tech-docs-writer.md` | + +--- + +## Quick Prompts (Copy → Paste into Claude Code) + +``` +"Load agents/depin-architect.md — I'm building a LoRa sensor network for air quality" + +"Load skill/zk-compression.md — I need to handle 100K device accounts without paying $40K/year in rent" + +"Load skill/depin-tokenomics.md — check if my emission schedule will hit a death spiral" + +"Run /depin-audit on my DePIN — program ID is [ADDRESS], token mint is [ADDRESS]" + +"Run /node-economics — 250M supply, 55% to operators, hardware cost $400, target 10K nodes" + +"Load skill/regulatory-rf-compliance.md — I'm deploying LoRa hotspots across US and EU" + +"Load skill/data-pricing-oracle.md — I want my data marketplace price to adjust automatically" + +"Load skill/adaptive-proof-engine.md — my H3 cells are reaching 30+ nodes and I need stronger proof" +``` + +--- + +## Cross-Skill Integration + +This skill is one of five coordinated Solana AI Kit skills.

data served | + +**Key design constraints:** +- Geographic distribution is the product — rewards must incentivize spreading out +- Proof of Coverage must be Sybil-resistant (a hotspot indoors can't fake outdoor coverage) +- H3 hex grid is the standard geographic unit (resolution 8 = ~0.7 km² cells) +- Revenue is denominated in Data Credits (stable USD-pegged) — prevents reward manipulation +

An unverified compressed account is unverified data. The Light Protocol SDK handles this automatically; do not bypass it with manual deserialization. + +2. **Indexer dependency is a production risk** — Compressed state depends on DAS API indexers (Helius). If the indexer goes down, reads fail. Mitigation: cache critical device state in a traditional PDA for frequently-read fields (operator, stake_lamports, is_jailed). The compressed account holds the bulk metadata. + +3. **Proof generation is CPU-intensive** — At 10K+ devices, off-chain proof generation requires dedicated compute. Budget for 1 proof-generation server per ~50K active devices at 1 heartbeat/hour frequency. Do not run this on your API server. + +4. **Never compress treasury, mint, or governance accounts** — These require instant direct reads and atomic writes. Compression overhead on high-value accounts is a security and reliability risk. Rule: if an account holds SOL/tokens or requires multisig, keep it uncompressed. + +5. **Compressed and uncompressed state must stay in sync** — If you maintain a hybrid registry (compressed device data + uncompressed stake escrow), ensure both are updated atomically within the same transaction or use a reconciliation service with idempotent retries. + +--- + +## Hybrid Architecture (Recommended for Most DePINs) + +For most DePINs the optimal approach is **not** fully compressed — it is hybrid: + +``` +┌─────────────────────────────────────────────────────┐ +│ RECOMMENDED HYBRID LAYOUT │ +├──────────────────────────┬──────────────────────────┤ +│ COMPRESSED (ZK) │ UNCOMPRESSED (PDA) │ +│ ─────────────────────── │ ─────────────────────── │ +│ Device ID │ Network Config │ +│ Owner pubkey │ Protocol Treasury │ +│ Location hash (H3) │ Token Mint Authority │ +│ Trust score (BPS) │ Governance State │ +│ Last heartbeat slot │ Oracle Feed Account │ +│ Cumulative rewards │ Stake Escrow Vaults │ +│ Firmware version │ Emergency Pause Flag │ +│ │ │ +│ Cost: ~0.000002 SOL/ │ Cost: ~0.002 SOL each │ +│ device │ (one per protocol account│ +│ 10M devices = 20 SOL │ not per device) │ +└──────────────────────────┴──────────────────────────┘ +``` + +**Migration path:** Start with PDAs (simpler).
