# 1.1 The Documents Blockchain
Commercio.network is an OPEN SOURCE PROJECT (opens new window) that gives companies the ability to sign and exchange documents using the blockchain technology and guarantee:
- Paternity the document was created by the declared sender
- Non-repudiation the sender cannot deny having digitally signed the document
- Integrity the document has not been altered during transport
There are two main groups of business documents:
- Structured: Mostly XMl (Invoices, orders, order confirmations etc)
- Unstructured: Mostly PDF (Contracts, forms, letters etc)
The network is organized through an international consortium (opens new window) of 100 independent companies. Any company, especially yours, is welcome to join the consortium and take advantage of the next decade technology... Today.
The Commercio.network is called The Documents Blockchain™ because it focuses on solving one core business problem : Legally Exchanging and signing business documents.
Our mission is to spread the blockchain technology to worldwide companies with a bold adoption plan:
- 100 Node validators companies to onboard...
- 100.000 IT companies to onboard...

We want to provide every IT Company in the world a simple, fast, profitable way to create value for them and their end customers with:
