(A.) Policy and legislation

(A.1) Policy objectives

Blockchain has great potential in providing an infrastructure for trusted, decentralised and disintermediated services beyond the financial sector.

While the FinTech industry has been an early adopter because of its earlyuse case of Bitcoin, blockchain is benefiting and has the potential to transformmany other industries. It is considered a foundational technology that some compare to the rise of the Internet in the early 90s. More than a technology, it could lead to a major institutional innovation by redefining the way we operate transactions, store and access information and share data (e.g. empowering patients to securely share e-health records and decide who to grant access to their data).

Many possible applications are being envisaged to deliver efficiency, immutability and transparency to the financial services industry, Fintech/Suptech actors, trust funds (e.g., for development or humanitarian programmes), eHealth, education, eGovernment, public registries, security certification of Internet of Things, Trusted Artificial Intelligence, food safety, managing intellectual property rights, extending eIDAS framework for eID management, etc.

It has also great potential for the private sector, in trading, contracting, supply chain management,traceability along industrial supply chains (e.g. on social & environmental conditions of work, on material composition or on the maintenance history of the item)and much more. It may also transform the governance of private organisations and of companies (concept of Decentralised Autonomous Organisation - DAO). Furthermore, from a regulatory and supervisory point of view, it could provide regulators with the same view into the data as the companies they are regulating, thereby reducing fraud and compliance costs and facilitating auditing.

Provisions must be taken at all stages to comply with the GDPR, AML regulations and other legal requirements.

However, this process is hindered by a lack of coherent harmonisation and interoperability that constitute obstacles to cross border and cross sector transactions. The responsibility for public policy-makers would be to support innovation within a safe and future-proof technological and regulatory environment, ensuring appropriate interoperability, transparency, accessibility, monitoring and governance.

In the context of the European Digital Single Market where the amount of online transactions and data is exploding, setting the right conditions for the advent of an open, trustworthy, transparent, compliant and authenticated transaction system is a real challenge for the EU. Existing decentralised environments lack trust, accountability, interoperability, regulatory certainty and mature governance models to interact among themselves and also with centralised systems.

Since 2018 the European Commission has been developing a proposal for the Regulation of Markets in Crypto-assets (MiCA) regulatory framework, which currently has achieved a status of an official document (COM/2020/593 final) and is being discussed with the European Parliament and the Council. The MiCA Regulation is a part of The European Commission’s “Digital Finance package” adopted on24September2020 which comprises updated strategy for digital finance and retail.

On June 3rd 2021 the Commission has published a proposal for a Regulation “amending Regulation (EU) No 910/2014 as regards establishing a framework for a European Digital Identity” (eIDAS2) that introduces, a new trust service for electronic ledgers, and the European Digital Identity Walled, an identification means for European physical and legal persons, based on Self Sovereign Identity principles.

(A.2) EC perspectiveand progress report

In order to engage in and contribute to the development of the needed standards, starting from September 2017, the Commission is organising workshops on blockchain standardisation and follows up the standardisation activities related to Blockchain and Distributed Ledger Technologies carried out by the different SDOs, such asISO,ITU-T, ETSI or CEN-CENELEC.

These workshops bring together standards development organisations, fora and consortia active in international BC/DLT standardisation, as well as key stakeholders, and representatives of PPPs like INATBA and deployment initiatives like the EBP.

On 17 June 2020 the European Commission organised “Joining Forces for Blockchain Standardisation” webinar to encourage collaboration and cohesion of ongoing standardisation activities and prevent emergence of conflicting standards. This webinar has been well received by blockchain standardisation community, it brought together more than 400 global blockchain standardisation experts together to discuss advances in standardisation of Identity, Interoperability, Governance, Smart Contracts. During this webinar the European Commision has run a survey to identify the most critical areas of blockchain standardisation where more cohesion is needed. Results were that “interoperability” would benefit the most, followed by “identity”, “smart contracts”, “governance” and “security”.

To bring together Horizon 2020 and blockchain standardisation communities the European Commission has set up a set of roundtable discussions “ICT Verticals and Horizontals for Blockchain Standardisation”. These roundtables took placeDuring the second half of 2020 and the start of 2021 within the following theme groups:

  • Fintech, Digital Assets and Smart Grids
  • Digital Society, Identity and Privacy
  • Digital Economy, SME’s, Industry and Supply chains
  • Cybersecurity
  • IoT
  • eHealth
  • Future Internet, Media and Big data
  • Sustainable Development Goals
  • Smart-Contracts
  • Artificial Intelligence

More than 70 Horizon 2020 projects have participated as well as standardisation experts of ISO, CEN/CENELEC, ETSI, ITU-T, IEEE, W3C and IETF.

The European Commission launched the EU Blockchain Observatory and Forum in February 2018, involving private stakeholders and public authorities in technical and regulatory discussions about the future development and applications of blockchain technology. Among its important tasks, it is gathering the best European experts in thematic workshops on important subjects such as Blockchain and GDPR, or blockchain innovation, and producing reports which will help European stakeholders to deploy blockchain based services in Europe.

On the 10th of April 2018, the European Blockchain Partnership (EBP) was launched, with 28 European countries agreeing, through a joint declaration to cooperate in the establishment of a European blockchain services infrastructure (EBSI) that will support the delivery of cross-border public services, through interoperability and open interfaces and with the highest standards of security. Today the EBP includes all EU Member States, Norway and Liechtenstain.

On 3rd April 2019 the Commission supported the launch of the International Association of Trusted Blockchain Applications – INATBA -, which brings together representatives of the stakeholders across the value chain. INATBA offers developers and users of DLT a global forum to interact with regulators and policy makers and bring blockchain technology to the next stage. It will support the development and adoption of interoperability guidelines, specifications and global standards, to enhance trusted, traceable, user-centric digital services, via a working group on standardisation to interact with standardisation organisations. On 11-13 November 2019 INATBA together with EU Blockchain Observatory and forum, Alastria and the European Commission co-organised the Global blockchain congress CONVERGENCE. INATBA has a dedicated Blockchain Standardisation working group.

The European Commission has already invested more than € 80 million in projects supporting the use of blockchain in technical and societal areas. Up to € 300 million should be further invested until the end of the EU funding programme Horizon 2020. Furthermore, the European Commission is launching the AI/Blockchain fund, which finances a portfolio of innovative AI/blockchain companies and contributes towards development of a dynamic investor community. Expected investment is up to € 300 million. In addition, more funding will be available through Horizon Europe R&I and the Digital Europe (DEP) Programmes.

W3C has formed a Blockchain Community Group, which is studying and evaluating technologies related to blockchain and use-cases such as interbank communications. Its work is complemented by a group on Blockchain and Decentralized Apps and one on Digital Assets.

W3C created the Decentralized Identifier Working Group (DID WG) URL-based identifiers (URIs) in use on the Web today (2019) require that the identifier be leased from an authority such as a Domain Name Registrar. A Decentralized Identifier (DID) is an identifier that does not need to be leased; its creation and use is possible without a central authority to manage it.

In addition to the “Blockchain Community Group” W3C has also a “Credential Community Group” ( which has developed key standards for SSI (Self-Sovereign Identity) including Decentralized Identifiers (DID) Data model and Syntax and Verifiable Claims Use Cases and Data Model.


The Decentralized Internet Infrastructure Research Group (DINRG) will investigate open research issues in decentralizing infrastructure services such as trust management, identity management, name resolution, resource/asset ownership management, and resource discovery. The focus of DINRG is on infrastructure services that can benefit from decentralization or that are difficult to realize in local, potentially connectivity-constrained networks. Other topics of interest are the investigation of economic drivers and incentives and the development and operation of experimental platforms. DINRG will operate in a technology- and solution-neutral manner, i.e., while the RG has an interest in distributed ledger technologies, it is not limited to specific technologies or implementation aspects.

More details of the DIN RG areavailable.


CEN and CENELEC established a Focus Group on Blockchain and Distributed Ledger Technologies to identify specific European standardisation needs (for example in the context of EU regulations such as GDPR and eIDAS), to map these standardisation needs with the current work items in ISO/TC 307 and to encourage further European participation in ISO/TC 307.

Following the conclusions of the Focus Group, CEN CENELEC set up the Joint Technical Committee JTC19 on Blockchain and Distributed Ledger Technologies CLC/JTC 19, working on the identification and adoption of international standards already available or under development and to pay attention towardsspecific European legislative and policy requirements supporting the development of the EU Digital Single Market. JTC 19 has established the first Working Group dedicated to Decentralised Identity Management. The JTC works in close contact with ISO/TC 307 Blockchain and distributed ledger technologies.



Permissioned distributed ledgers are the kind of DLT best qualified to address most of the use cases of interest to the industry and governmental institutions.

The ETSI ISG PDL is committed to analyse and provide the foundations for the operation of permissioned distributed ledgers, with the ultimate purpose of creating an open ecosystem of industrial solutions to be deployed by different sectors, fostering the application of these technologies, and therefore contributing to consolidate the trust and dependability on information technologies supported by global, open telecommunications networks. The ISG PDL incorporates research and new development results in the field as they become available. The group is actively working to facilitate the coordination and cooperation between relevant standardisation bodies and open source projects.
