# Build

> Build with QBTC: architecture, post-quantum cryptography (ML-DSA), consensus, claim mechanism, node operation, and API reference.

Documentation for developers, integrators, and node operators. If you want to understand QBTC at a conceptual level first, see the [Learn](/learn/what-is-qbtc) section.

## Start here

* [Architecture](/build/architecture), a tour of the chain daemon, the bifrost sidecar, the ZK proof service, and how Bitcoin's state is mirrored.
* [Quantum Resistance (ML-DSA)](/build/quantum-resistance), the cryptographic substrate.
* [Consensus & Validators](/build/consensus), the CometBFT fork and validator economics.
* [Claim Mechanism](/build/claim-mechanism), how a Bitcoin holder converts a claim into spendable QBTC.

## Run a node

* [Running a Node](/build/running-a-node), hardware, install, configuration. *Coming soon as testnet stabilizes.*

## Integrate

* [API Reference](/build/api-reference), HTTP and RPC surfaces. *Coming soon.*

## Source

* Chain code: [github.com/btcq-org](https://github.com/btcq-org).
* Modules in use are documented in the [Protocol Specification](/research/protocol-spec).
