# DCN — The Open Standard for Physical Digital Assets

**Digital Crypto Note (DCN)** is an open standard for creating secure, interoperable **Physical Digital Assets** backed by blockchain and digital infrastructure.

DCN defines a common architecture for:

* Digital Cash
* Stablecoin Notes
* CBDCs
* Gift Cards
* Event Tickets
* Payroll
* Government Benefits
* Transit
* Loyalty
* Certificates
* Digital Identity
* Collectibles
* Future Physical Digital Assets

The standard covers secure hardware, NFC communication, wallet architecture, multi-chain support, payments, ownership, verification, publishing, manufacturing, SDKs, APIs, governance, and certification.

## Vision

> **DCN — The Open Standard for Physical Digital Assets.**

DCN is not a cryptocurrency, blockchain, wallet, or proprietary payment network.

It is an open infrastructure standard designed to allow independent:

**Publishers → Manufacturers → Wallets → Merchants → Developers → Blockchain Networks**

to create and interact with trusted Physical Digital Assets through a common protocol.

***

## DCN v1.0

The first specification includes:

* System Architecture
* Physical Digital Asset Model
* Secure Hardware
* Wallet Architecture
* Multi-Chain Support
* Security Architecture
* Ownership & Trust
* Payment Protocol
* Merchant Acceptance
* Publisher Platform
* Manufacturing
* Verification Services
* SDKs
* APIs
* DCN Foundation & Governance
* Business Model
* Use Cases
* Future Roadmap
* Standards
* Technical Appendices

***

## Status

**DCN v1.0 — Foundation Draft**

The specification is currently intended for technical review, prototype development, interoperability testing, and ecosystem collaboration.

***

## Contributing

DCN is designed as an open standard.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.dcn.foundation/readme.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
