The Legal Evidentiary Value of Blockchain (Distributed Ledger Technology) in Proof

This article examines the probative value of blockchain (distributed ledger technology) in legal proof. It highlights the technology’s core features—decentralization, immutability, cryptography, and time-stamping—and assesses how they fit within rules of evidence, particularly the requirements of electronic writing and electronic signature. The study also discusses the extent of legislative recognition in Morocco and comparative systems, with a focus on identity attribution and the link between a digital record and its author. It concludes that blockchain records may carry increasing persuasive force, while full evidentiary equivalence requires clearer regulatory frameworks and trusted digital services to ensure integrity and reliability.
