Blockchain and Distributed Ledger Technologies (DLT) continue to play a transformative role in the modern digital economy and are regarded as a foundational technology in the European single digital marketplace. This report is the second in a series of three Landscape Reports to be published by SEEBLOCKS.eu that provide an extensive analysis of the existing international standards landscape, identifying gaps, and presenting some concrete responses to address these, aiming to foster a cohesive and resilient blockchain ecosystem. The first report D3.1 Blockchain & DLT Standards & Landscape Report described the context of international standards-making, elaborating the formal consensus processes that underpin the voluntary standards-making activities at international standards development organisations (SDOs) such as ISO, IEC and CEN contrasting these with the informal consensus-building that takes place at IEFT, W3C and other open blockchain protocols such as Bitcoin, Ethereum and other public blockchains. This new report focuses on the current state of the art in blockchain standards, reviews recent industry publications on emerging standards requirements and identifies common perspectives, gaps and priority areas for future standardisation, ensuring that our ongoing efforts are aligned with the needs of the market and society. The SEEBLOCKS.eu initiative remains committed to accelerating the interoperability, preparedness, and resilience of the EU single digital marketplace through targeted research and development in blockchain and DLT open standards. This report aligns with SEEBLOCKS.eu’s mission to offer strategic analysis of the blockchain landscape and proposes actions to enhance standardisation efforts. This report focuses on several key areas, including the current adoption and use cases of blockchain technology, recent technological advancements, standardisation efforts, identified gaps, and future directions for research, development, and standardisation initiatives. As a mid-term analysis, this report serves as a critical checkpoint for the SEEBLOCKS.eu project, ensuring that efforts are targeted and effective in supporting the growth and resilience of the European single digital marketplace.
