# License and terms

Bloxchain has two legal layers: the open-source Bloxchain Protocol, which is licensed code, and the hosted Bloxchain Platform, which is a service with its own terms. This page says which applies where.

## Bloxchain Protocol (open source)

The Protocol smart contracts, the TypeScript SDK (`@bloxchain/sdk`) and the upstream documentation in [Bloxchain-Protocol](https://github.com/PracticalParticle/Bloxchain-Protocol/tree/99beac2d6e6d7567c23b25cecaf6f4053f31c987) are released under the **Mozilla Public License 2.0 (MPL-2.0)** unless a subdirectory states otherwise.

* [LICENSE](https://github.com/PracticalParticle/Bloxchain-Protocol/blob/99beac2d6e6d7567c23b25cecaf6f4053f31c987/LICENSE) at the pinned commit
* Example contracts under `contracts/examples/` may carry per-folder licenses; check each folder.

Deploying, forking or embedding Protocol code is governed by MPL-2.0. Using the Platform does not change that license, and the Platform does not relicense the Protocol.

## Bloxchain Platform (hosted service)

The Platform at bloxchain.app is a separate hosted product operated by Particle Crypto Security Ltd. It is not covered by the Protocol's MPL-2.0 license. Using it means accepting the product terms shown in the app:

### What the Platform is not

* A custodian of private keys or funds.
* A replacement for the on-chain policy. The chain enforces; the Platform displays and orchestrates.
* Legal, tax or investment advice.

## This documentation site

The pages in [bloxchain-docs](https://github.com/PracticalParticle/bloxchain-docs) describe how to use the Platform and the Protocol. The Protocol section is vendored from the Protocol repository at a [pinned commit](/resources/releases.md#protocol-documentation-pin) and keeps its MPL-2.0 license. Documentation prose is informational and is not a substitute for the product terms or the Protocol license.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bloxchain.app/resources/license.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
