Cross-Chain Interaction publication case

EVEN distributed service for document storage

We are closing the year 2019 with the release of MVP based on our platform. We have created a service for storing documents and precisely controlling access to them.
Dec 25, 2019

The basic function of the service is the storage of documents in a distributed EVEN network. Today, users have two standard options: store documents locally or in the cloud. When a document repository is required to interact with other users, the cloud is the most frequent option.

Not all documents can be published on third-party cloud services. Many corporate documents require control over their distribution. Therefore, services such as digital data rooms and internal DLP solutions are created.

The document management service from EVEN will allow you to exchange data within the company and with other organizations while maintaining full control over the process. Documents are physically stored locally at their owners' devices and on trusted servers within companies. Each participant stores exactly those documents that are important to him.

Characteristics of document storage

The service is suitable for the exchange of confidential documents, for example, personal data, between organizations.

  • Data storage can be limited to specific devices at the disposal of interacting organizations.
  • All documents are stored encrypted.
  • The service stores all versions of documents and deleted data, so no one can make changes unilaterally.

Document Access Control

Access is controlled at several levels:

  • Physical storage on specific devices with DLP policies applied to them. You can use a VPN network to exchange data between nodes.
  • You can specify 2 types of users: node holders and users of the web service, then provide them with different rights.
  • Access to the web service can be arranged according to the credentials in the organization (Single Sign-On).

Current product features

  1. So, the simplest thing you can do is upload documents through the service web interface. After downloading, the document will be available to all users of the service by the link.

  2. The second option is to add the document through your node. To do this, you publish the selected folder and transfer documents there in the standard way, through Explorer.

    In a minute, your document will be available to users of the web service both in the document list and in the Nodes section (list of documents in the last folder of your node):
    The same files are on web service
    The same files are on web service

  3. Version control is implemented as node content tracking. For example, the computer of the legal department locally stores the latest and most relevant documents, but the service also remembers previous versions. Deleted and changed documents remain stored in the web service node, but do not load the disk space of other devices. You can view a set of documents relevant for a specific date in the Nodes section:

  4. Authentification of documents. A hash is assigned to every uploaded document. The system can store several documents with the same hash, while their names may be different. If the document was edited, then the hash will also change. Suppose an employee wants to check whether his version of the contract is relevant and published on the computer of the legal department. To do this, he can generate a hash on the document authentification page and make sure that the document is published.


Since the service is on the MVP stage, it will develop. If you have a suitable scenario in which our product could be applied, contact us. We will be glad to hold a demonstration, discuss our plans on product development and implementation.
