# A4

### Overview

The A4 tokenization model enables the creation of smart contracts that issue text-based tokens with the A4 output format.

***

### Multiple Pages

A4 is engineered to condense multiple outputs into a single token, introducing a token built-in pagination UI and UX.&#x20;

As a result, A4 enables the tokenization of documents with multiple pages.

***

### Intended Use Cases

A4 is intended for the tokenization of documents.

The model is designed for use cases in that a document demands the highest level of immutability, permanency, and auditability of text records. This applies to critical contexts which require utmost provenance, from AI to legal to literature.

#### AI

The A4 model can be integrated as part of AI-related frameworks.

A4 ensures that every critical piece of text-based content generated during AI-related processes can be permanently recorded, transparent, and immutable, offering unparalleled provenance — from tokenizing AI models performance reports, explanation documents, and model versioning to tokenizing AI models complicance audits, algorithms intellectual property (IP), and data provenance and lineage.

#### Legal

A4 can be employed for tokenizing traditional critical legal documents, such as contract terms, financial statements, title deeds, and patents.

#### Literature

A4 can be employed for tokenizing critical literature documents, such as research articles, academic papers, technical whitepapers, and manifestos.
