## What This Repository Contains

This repository provides the client-side developer SDK used to interact with the canonical Quantova network: post-quantum key generation and signing (Falcon, Dilithium, SPHINCS+), the `q_*` JSON-RPC client, the QVM contract layer (Solidity ABI encoding/decoding and event-log decoding), QNS `.q` name resolution, fee and gas estimation, batch requests, event hooks, a REST gateway client, and the `qweb3-cli` toolbelt. It does not contain Quantova consensus, runtime, or node implementation code.

## Application and Integration Clarification

Building applications, wallets, services, dashboards, integrations, and developer tooling on top of this SDK that interact with the canonical Quantova network is explicitly permitted under the BUSL-1.1 license and does not constitute restricted "Production Use." Using this SDK to submit transactions, query state, manage keys, and operate infrastructure on the Quantova network does not create additional licensing obligations.

## Validator and Node Operator Clarification

Running a validator node or full node on the canonical Quantova network, and using this SDK to support such operation, is explicitly permitted under the BUSL-1.1 license and does not constitute restricted "Production Use."

A formal clarification for validators, node operators, exchanges, custodians, and infrastructure providers is provided at:

```
/docs/validators/licensing.md
```

Participation in staking, consensus, block production, and transaction processing on the Quantova network does not create additional licensing obligations.

## Restricted Use Under BUSL-1.1

The BUSL-1.1 license restricts use of the Licensed Work, together with Quantova consensus, runtime, and QVM code, to launch, operate, or market a competing blockchain network or distributed ledger that is not the canonical Quantova network. It further restricts offering the Licensed Work to third parties as a hosted or managed service, or otherwise using the Licensed Work to provide a commercial product or service that competes with the products or services of the Licensor.

This restriction applies to, but is not limited to:

- Independent or derivative mainnets
- Forks marketed as separate networks
- Networks intended to replace or compete with Quantova
- SDK distributions repackaged or offered as a competing managed service

Forking, modifying, or analyzing the code for testing, auditing, research, or contribution purposes is permitted.

## Canonical Network Definition

For licensing and authorization purposes, the canonical Quantova network is defined by all of the following:

- Official signed source releases published by Quantova Inc
- A unique post-quantum genesis hash
- Signed runtime and protocol artifacts
- Post-quantum cryptographic signatures, including CRYSTALS-Dilithium and Falcon

Any network deployment that does not match these identifiers is not the Quantova network and is not authorized under the Quantova BUSL license.

## Documentation and Specifications

Documentation, research materials, and protocol specifications included in this repository are licensed under BUSL-1.1 unless explicitly stated otherwise within the relevant file or directory. Documentation is provided for informational and technical reference purposes and reflects protocol behavior enforced by code.

## Third-Party Software

This repository depends on third-party open-source software. Such components remain subject to their original licenses. This includes, among others, the Quantova `@quantova/*` packages (derived from polkadot-js, licensed under Apache-2.0, with applicable trademark notices) and `axios` (MIT). Where applicable, third-party license notices are provided in:

```
/THIRD_PARTY_LICENSES.md
```

or within dependency manifests (for example, `package.json`).

## No Legal, Financial, or Regulatory Advice

Nothing in this repository, including documentation and specifications, constitutes legal, financial, or regulatory advice. Operators, validators, and users are responsible for ensuring compliance with applicable laws and regulations in their respective jurisdictions.

## Institutional and Licensing Inquiries

Licensing, institutional, and regulatory inquiries relating to the Quantova technology stack should be directed through official Quantova channels published by Quantova Inc.

Protocol identity and licensing intent are cryptographically anchored at genesis via an immutable on-chain commitment.
