How It Works

CARGE publishes compliance schemas on the blockchain. AI agents can read them, execute the required steps, and generate cryptographic proof of completion. Every regulatory process becomes automated and verifiable.

1️⃣ Compliance Schema On-Chain

Regulations are published as structured schemas on the blockchain: step-by-step instructions, required resources, validation rules (JSON Schema). Example: W3C Verifiable Credentials for copyright, EBSI compliance, multi-party agreements.

2️⃣ AI Executes via MCP

AI agents connect via Model Context Protocol (MCP), read the on-chain schema, and execute each step automatically. The agent collects data through natural language dialogue, validates against the schema, and builds the compliant credential. No human interpretation needed.

3️⃣ Cryptographic Proof Recorded

Every step generates a crypto-trail: who executed it, when, what data was produced, and cryptographic signatures. The final proof is stored on IPFS (encrypted), with its hash recorded on-chain. This website lets anyone verify the complete audit trail instantly.

Use Cases

Any compliance process can be transformed into executable code. Here are examples across different industries and regulations.

🎨 Copyright & IP (EBSI)

AI interviews creators in natural language, builds W3C Verifiable Credentials following EBSI standards, manages multi-party authorship with individual signatures. Submitted to EU trusted registries with complete audit trail. Cost: €0.05 vs €5+ traditional.

🏢 Corporate Compliance

GDPR, AML/KYC, financial reporting schemas published on-chain. AI agents execute compliance workflows automatically, collect required documentation, validate completeness, and generate auditable proof. Every step timestamped and signed.

📜 Legal Documents

Contracts, NDAs, licensing agreements with compliance templates on-chain. AI ensures all required clauses are present, validates against legal frameworks, collects signatures from all parties. Immutable record of who agreed to what, when.

🔬 Academic & Research

Research data management plans, ethics compliance, multi-institution collaborations. AI guides researchers through institutional requirements, validates data collection processes, manages contributor attributions. Full provenance chain for reproducibility.

🏗️ Supply Chain

Product certifications, quality control, sustainability compliance. On-chain schemas define standards (ISO, CE marking, ESG criteria). AI validates supplier documents, tracks multi-stage processes, generates certificates. Transparent audit trail for consumers and regulators.

🌐 Custom Workflows

Any organization can publish their compliance schemas on-chain. Define your process as: instructions + resources + validation rules. AI agents execute it automatically. Every execution generates verifiable proof. Compliance becomes programmable.

Technical Architecture

CARGE is built on proven decentralized technologies with a focus on interoperability and standards compliance.

⛓️ Blockchain Layer

Substrate/Polkadot blockchain with custom pallets: pallet-pki (identity management), pallet-crypto-trails (audit trails), pallet-compliance (schema storage). EVM-compatible via Frontier for maximum interoperability. Transaction cost: ~€0.05 vs €5+ on Ethereum.

🤖 AI Integration (MCP)

Model Context Protocol (MCP) server bridges AI agents to blockchain. Currently works with Claude Desktop (native support). AI reads compliance schemas, executes workflows through natural dialogue, validates outputs against JSON Schema. Architecture is extensible to other LLMs. Local processing possible for GDPR compliance.

📦 Storage & Privacy

IPFS/Helia for decentralized content storage. ChaCha20-Poly1305 encryption for sensitive data. X25519 ECDH for multi-party workflows. Only content hashes on-chain, full data encrypted off-chain. Users control their keys and data. GDPR-compatible architecture.

🔗 Standards & Interoperability

W3C Verifiable Credentials as output format. Compatible with EBSI trusted registries, eIDAS certificates for identity verification. Dublin Core metadata, Creative Commons licensing. Open-source components (license TBD). Built to connect, not compete, with existing systems.
