Blockchain and Distributed Ledger Technologies (DLTs) are among the most promising developments in ICT for sharing data and managing transactions in a decentralised, controlled manner. The use of Blockchain and DLTs continues to grow rapidly, notably in the context of Industry 4.0, thus creating both new opportunities and challenges for business and society. In order to contribute to ensuring a smooth and safe adoption of new technologies in Europe, CEN and CENELEC recently established new CEN-CENELEC JTC 19 ‘Blockchain and Distributed Ledger Technologies’, based on the recommendations presented in the CEN-CENELEC White Paper on ‘Recommendations for Successful Adoption in Europe of Emerging Technical Standards on Distributed Ledger/Blockchain Technologies’.
