Patent Explainer: ClawMiner — Hardware AI Agent Device (F-004)

What F-004 Does

F-004 describes a portable hardware device called "ClawMiner" that integrates four capabilities into a single unit: a tamper-resistant secure element for key storage, an AI agent capable of autonomous task execution, a multi-chain blockchain wallet, and an inscription engine that records every action the AI agent takes as an immutable audit trail on the BSV blockchain.

The device also introduces a "Proof of Indexing" (PoI) consensus mechanism. Instead of performing wasteful hash computations to mine tokens (traditional Proof of Work), the ClawMiner earns tokens by performing productive data-indexing work — cataloguing blockchain transactions, building search indices, processing datasets. The computational effort that would otherwise be wasted on arbitrary hashing is redirected toward useful labour.

This is the patent for a hardware device where AI does real work, every action is permanently recorded, keys never leave the device, and the work itself earns tokens.

The Problem It Solves

1. Lack of auditability. Software-based AI agents log actions to databases or cloud services that can be altered, deleted, or become unavailable. There is no guarantee of immutability. When an AI agent executes a financial transaction, signs a document, or interacts with an external service on your behalf, there is no standardised, tamper-proof record.

2. Key security. AI agents that manage cryptographic keys typically store them in software wallets or cloud-based key management services, both of which are vulnerable to remote exploitation, insider threats, and single points of failure.

3. Fragmented multi-chain activity. Users operating across multiple blockchains (BSV, Ethereum, Solana) have no unified mechanism to create a single, coherent audit trail of all cross-chain activity. Each chain's records exist in isolation.

4. Consensus inefficiency. Traditional Proof of Work consensus consumes vast quantities of energy performing computations that serve no purpose beyond securing the network. There is no mechanism to redirect that effort toward useful indexing, cataloguing, or data-processing work.

5. IP and data provenance. When an AI agent generates intellectual property (text, images, code, datasets), there is no built-in mechanism to timestamp, sign, and register that output in a manner that establishes provenance and ownership at the moment of creation.

How It Works

Secure Element / Key Storage Module

A tamper-resistant hardware secure element stores private keys such that they cannot be extracted from the device. All signing operations occur within the secure element itself. The element supports key derivation for multiple blockchain networks from a single master seed, enabling the device to hold keys for BSV, Ethereum, Solana, and other supported chains simultaneously.

The secure element is physically bonded to the device's main processor board. Tamper-detection circuits cause key erasure if physical intrusion is detected.

AI Agent Module

The AI agent module comprises a processor (ARM-based or RISC-V) running a lightweight inference engine capable of executing AI models locally. The agent can:

• Accept task instructions from the device owner via local interface (USB, Bluetooth, Wi-Fi) or via authenticated remote commands
• Execute tasks autonomously: data retrieval, content generation, file processing, API interaction, transaction construction, blockchain monitoring
• Generate structured action logs for every operation performed
• Submit action logs to the inscription engine for on-chain recording

The AI agent operates within a sandboxed execution environment. Model updates are signed by the device manufacturer and verified by the secure element before installation.

Multi-Chain Wallet Module

The wallet module manages addresses, balances, and transaction construction for multiple blockchain networks. It provides a unified interface for constructing, signing, and broadcasting transactions across supported blockchains. It includes a UTXO manager for UTXO-based chains (BSV, BTC, BCH) and a nonce manager for account-based chains (Ethereum, Solana), a fee estimation engine, and a transaction queue.

All transaction signing is performed by the secure element. The wallet module constructs unsigned transactions and passes them to the secure element for signing.

Inscription Engine

The inscription engine is the core novel component. It receives structured action logs from the AI agent module, transaction records from the wallet module, and any generated content, then inscribes them as immutable records on the BSV blockchain.

1. Action capture — Every action by the AI agent generates a structured log entry: timestamp, action type, input parameters, output summary, cryptographic hash of any generated content, and references to any blockchain transactions executed.
2. Merkle aggregation — Action log entries are aggregated into a Merkle tree at configurable intervals (every N actions, every T seconds, or every block). The Merkle root is the primary datum inscribed on-chain.
3. On-chain inscription — The Merkle root, together with metadata (device ID, epoch number, chain references), is inscribed as a BSV transaction output using OP_RETURN or OP_PUSH_DATA protocol.
4. Cross-chain references — When the wallet module executes transactions on secondary chains (Ethereum, Solana, etc.), the transaction hashes from those chains are included in the BSV inscription, creating a unified audit trail linking activity across all chains back to a single BSV record.
5. Recursive inscription — Inscriptions reference prior inscriptions, forming a traversable "audit chain" that can be used to reconstruct the complete operational history of the device.

Proof of Indexing (PoI) Consensus Mechanism

Rather than performing arbitrary hash computations to mine tokens, the ClawMiner earns tokens by performing verifiable indexing work:

1. Task assignment — The PoI protocol assigns indexing tasks to participating devices. Tasks include: indexing blockchain transaction data, cataloguing content inscriptions, building search indices for on-chain data, verifying the integrity of existing inscriptions, and processing structured datasets.
2. Work verification — Upon completion, the device submits a proof comprising: the task identifier, the resulting index data (or a hash thereof), and a cryptographic signature from the device's secure element. Verifier nodes check the proof against independently computed results.
3. Token minting — Upon successful verification, tokens (e.g., $402 HTM tokens under the BSV-21 protocol) are minted and assigned to the device's wallet address. The minting rate is proportional to the quantity and complexity of verified indexing work.
4. Difficulty adjustment — The PoI protocol adjusts task difficulty and token reward rates to maintain a target emission schedule, analogous to Bitcoin's difficulty adjustment but applied to indexing work.

Recursive Tokenisation

The device's operational output (indexed data, generated content, audit records) can itself be tokenised as BSV-20 or BSV-21 tokens. These tokens reference the audit inscriptions that prove the output's provenance. Token holders can verify the entire chain of provenance from token back to the original AI agent action that generated the underlying asset.

Device Form Factor

The ClawMiner is designed as a compact, portable unit approximately the size of a standard external hard drive. It comprises:

• An ARM or RISC-V system-on-chip (SoC) with integrated neural processing unit (NPU)
• A hardware secure element (e.g., ATECC608 or equivalent)
• Persistent storage (eMMC or NVMe SSD) for model weights, index data, and transaction queues
• Connectivity: Wi-Fi, Bluetooth, USB-C, and optional Ethernet via adapter
• An LED status display or small OLED screen for operational status
• A physical confirmation button for high-value transaction authorisation
