Blockchain and Distributed Ledgers as Trusted Recordkeeping Systems: An Archival Theoretic Evaluation Framework
Download as PPTX, PDF3 likes998 views
Blockchain and distributed ledgers show potential as trusted recordkeeping systems according to archival theory. The document discusses an evaluation framework for assessing blockchain-based recordkeeping based on key archival principles like trust, accuracy, reliability, and persistence over time. It provides examples of using blockchain for health records in Estonia where patient data, documents, and audit logs are stored immutably. The architecture ensures integrity and completeness from creation onward while maintaining patient identity and authenticity of records.

- 6. Estonian E-Health Recordkeeping • The most important data elements managed in the e-Health register are: • documents (Dokumendid): documents about an healthcare occurrence (f.ex. visit to a doctor, surgery, analysis in a lab); • patient data (Patsiendid); • Relations register (Viidaregister): relations between patients and documents; • Relations audit (Viidaregistri audit) and patient audit (Patsientide audit): technical audit data on the integrity of the according relations and patient tables; • The “documents” are kept in XML format. In addition most “documents” are also digitally signed and kept in the table in parallel
