Best Practices

Guided by the objective to deliver a targeted, democratic, and industry-driven initiative to support European interests in standardisation within the Blockchain/DLT domain, the SEEBLOCKS.eu team has embraced the challenge of identifying best practices that will make it easier for companies to comply with current regulations.

Given that existing regulations often provide only broad guidelines on desired behaviours, leaving significant room for interpretation and uncertainty in practical implementation, the team has focused on addressing this challenge. Specifically, they have identified six key areas of interest (Sustainability, Scalability, Accountability, Privacy, Security and Trust) in which best practices have been developed to bridge the gap between abstract regulatory principles and concrete technical solutions. In doing so, SEEBLOCKS.eu aims to establish a standardized and compliant blockchain ecosystem that not only aligns with European regulatory frameworks but also promotes innovation, while ensuring security, transparency and trust.

Each best practice is indexed and classified according to the areas of interest, within a taxonomy that refines the special goals and requirements associated with those areas. A detailed description of each best practice is provided, along with references to additional published material.

The European Blockchain Sandbox

The European Blockchain Sandbox provides valuable insights into the implementation of blockchain solutions across various sectors. To support a compliant and effective uptake of these technologies, the SEEBLOCKS.eu team has developed a comprehensive report that, starting from the use cases emerging from the sandbox, illustrates how these best practices can facilitate the responsible adoption of blockchain solutions throughout Europe. Latest release on best practices from the European Blockchain Sandbox can be found here.

In addition, we recommend to the reader the following report: Beck, R. & Agerskov, S. (Eds.). (2024). Ethical Guidelines for Blockchain Systems. Copenhagen, Denmark: European Blockchain Center. It may be accessed here.

We hope that you will enjoy exploring this collection and deepening your knowledge of blockchain best practices.
