Unified eXchange Platform (UXP) is a technology that enables peer-to-peer data exchange over encrypted and mutually authenticated channels. It is based on a decentralised architecture where each peer has an information system that will be connected with other peers’ systems.

UXP is developed by Cybernetica based on the experience we have gained through the creation and continuous improvement of the Estonian X-Road system for nearly two decades and our independent research in the fields of interoperability, information security, and information governance. Today, UXP is used by governments including those of Aruba, Bahamas, Benin, Greenland, Haiti, Namibia, Tunisia, and Ukraine, also by the financial sector in Japan, healthcare sector in the US and has been piloted by NATO.

UXP brings together data from organisations, information systems, and databases. It provides crucial components for interoperability and data exchange in a secure and standardised way. UXP allows service providers to retain control over their systems and data, yet making them a member of an infinitely scalable and decentralised data exchange network.


To achieve confidentiality requirements, all the data exchanged over the system is encrypted according to a security protocol to create a channel between the counterparts. Furthermore, peer-to-peer data exchange only happens between parties that have reached an agreement to disclose their data to one another, which means that they communicate directly with each other.


To ensure integrity and evidentiary value, the Security Server (a local component in the data exchange system) signs all the outgoing messages with the member’s signing key. All of the signed messages are saved to a log that is periodically time-stamped to ensure long-term validity of the signatures. The time-stamped signatures can be extracted from the log and presented to third parties for verification.


A distributed architecture ensures high availability of the infrastructure with a low number of coordinating services (governing components). Several security mechanisms have been built into the servers to protect against denial of service (DoS) attacks. Redundancy and load balancing are used for critical components to guarantee continuous functioning of the infrastructure.

The UXP system needs at least the following participants:
