'''X-Road''' is a centrally managed distributed Data Exchange Layer (DXL) between information systems.<ref name=":0">{{Cite web|url=https://x-road.global/|title=X-Road® Data Exchange Layer|website=X-Road® Data Exchange Layer|language=en-US|access-date=2019-10-11}}</ref><ref>{{Cite web|url=http://x-tee.html/|title=Data Exchange Layer X-tee {{!}} Estonian Information System Authority|website=x-tee.html|language=en|access-date=2019-10-11}}{{Dead link|date=July 2025 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Organizations can exchange information over the Internet using X-Road to ensure confidentiality, integrity and interoperability between data exchange parties.<ref name=":0" />
The first X-Road iteration was developed and launched by Estonia's Information System Authority (RIA) in 2001. The source code of its central components were released on October 3, 2016 under an MIT License.<ref name="VRT_2016_MIT_XRoad" /> By February 7, 2018, Finland's and Estonia's data exchange layers were connected to one another.<ref name="VRK_Data_Exchange" /> In 2017, Finland and Estonia established the Nordic Institute for Interoperability Solutions (NIIS) to continue the development of the X-Road core.<ref name="NIIS" />
==Features== According to their web page, "The X-Road is an open source data exchange layer solution that enables organizations to exchange information over the Internet. The X-Road is a centrally managed distributed integration layer between Information Systems that provides a standardized and secure way to produce and consume services. The X-Road ensures confidentiality, integrity and interoperability between data exchange parties."<ref name="NIIS_Kivimäki_2018"/>
A unique differentiator of X-Road compared to other governmental API exchange platforms, is the institution of decentralized peer-to-peer communication for API transactions. In this structure, organizations maintain and provide service endpoints for various transactions. These peer-to-peer transactions occur over the general internet and secure data exchange is enforced using Public Key Infrastructure concepts. Each peer who wishes to exchange data holds a unique set of key pairs for both digital signatures and authentication.
==History==
X-Road was started in 1998 as a pilot project under the Ministry of Economy and Communications, and the first prototype was publicly presented in 2000. One of the main reasons behind architectural choice of distributed data storage was a massive data leak of 1996, where government contractor and computer specialist Imre Perli created and marketed a "superdatabase" containing personal data from various government sources.<ref>{{Cite web|url=https://blog.ria.ee/sissejuhatus-x-teesse-osa-1/|title=Sissejuhatus X-teesse (osa 1)|last=Veldre|first=Anto|date=August 28, 2015|website=Information System Authority blog|access-date=February 4, 2020}}</ref>
