Learn about the DIGITAL Building Blocks and how they help to bring digital technology to businesses, citizens and public administrations.Let's create a Digital Europe, together.

Have you ever wondered why our health records and social benefits are often paper based and bound by national borders, while citizens and organisations enjoy the freedom of movement? Why aren't our records digitally transferred across the border with us? While these are only two examples, they show that the European Digital Single Market is still not a reality - but we are building it.

The Digital Europe Programme (DIGITAL) (2021-2027) is an EU funding programme aiming to accelerate the digital transformation of public administrations, facilitate interoperability as a core enabler of Europe’s digital autonomy, and foster the uptake of interoperable cross-border and cross-sector public services in alignment with regulatory requirements. The DIGITAL Building Blocks are an integral part of realising these objectives.

A Building Block is an open and reusable digital solution. It can take the shape of a framework, a standard, a software, or a software as a service (SaaS), or any combination thereof. Building Blocks are endorsed by the European Commission and ensure that your digital service is both fully compatible with others on the market and compliant with European legislation and standards. Building Blocks enable commonly needed functionalities, such as trusted authentication, secure data exchange, or electronic invoicing, so that service providers don't have to reinvent the wheel. By spreading the use of these DIGITAL Building Blocks based on European legislation and open standards, the result is an EU wide digital service network that is interoperable, cost-effective and secure. 

This portal is a one-stop-shop for information about the DIGITAL Building Blocks. It provides access to tools, services and software that can be used in any European project to facilitate the delivery of digital public services across borders.

The Digital Europe Programme aims to accelerate the economic recovery and shape the digital transformation of Europe’s society and economy, bringing benefits to everyone, but in particular to small and medium-sized enterprises.

This portal is home of six DIGITAL Building Blocks 

  1. eDelivery addresses European public and private sector organisations’ needs to exchange digital data and documents securely and reliably. We offer specifications, sample software and support services to help organisations set up and operate their own message exchange infrastructures. Our solution is based on global standards and follows the eIDAS Regulation’s security requirements. 
  2. eID helps to electronically identify citizens, businesses and public authorities across Europe. We support the creation of the technical infrastructure and offer services to help public authorities get started in complying with the eIDAS regulation. Having an eID solution in place will enhance economic growth and sustainable development by ensuring access to both public and private online services across borders in an easy to access, secure and cost-effective manner.
  3. eInvoicing: The eInvoicing DIGITAL Building Block supports the implementation of electronic invoices according to the EU Directive and compliance with the European standard. The European Commission provides supporting technical resources (e.g. validation artefacts and code lists) through a Registry to implement the European standard on eInvoicing, supporting stakeholders to issue, send, receive, and process eInvoices seamlessly across Europe.
  4. We built eSignature to help you create and verify electronic signatures more efficiently and paper free. Like a handwritten signature in the offline world, an electronic signature is a legal concept capturing the signatory's intent to be bound by the terms of the signed document.  Our solution is compliant with the eIDAS Regulation, secure and most importantly, recognised all over Europe.
  5. The Once-Only Technical System connects EU public authorities, so they can exchange official documents and data at the citizen’s request. It puts into practice the Once-Only Principle, which states that citizens should not be forced to provide information to authorities if another authority already holds that information in electronic format.
  6. The European Blockchain Services Infrastructure (EBSI) is a joint initiative from the European Commission and the European Blockchain Partnership (EBP). EBSI’s vision is to leverage blockchain to accelerate the creation of cross-border services for public administrations and their ecosystems. Since 2020, EBSI is deploying a network of distributed nodes across Europe, supporting applications for selected use cases.
