What the study found
The study found that blockchain technology can create reliable digital records, but technical security by itself does not make those records legally certain in civil litigation. It also found that blockchain records are most effective in limited situations, especially when they document activity directly on a blockchain network.
Why the authors say this matters
The authors conclude that integrating blockchain into evidence law requires clear legal rules that balance technical reliability with procedural safeguards. They also recommend specific admissibility criteria, standardised verification methods, judicial training, and coordination with international standards such as UNCITRAL and EU regulations.
What the researchers tested
The article used comparative legal analysis to examine how different legal systems treat blockchain evidence in civil litigation. It compared China, the United States, the European Union, France, Germany, the United Kingdom, and Türkiye.
What worked and what didn't
The findings indicate three situations where blockchain evidence is most effective: proving transactions carried out directly on blockchain networks, acting as an electronic detection tool for transactions outside the network, and recording real-world events directly onto blockchain systems. The study also reports difficulties across jurisdictions, including no harmonised standards, attribution problems, the "garbage in, garbage out" issue, and the need for expert testimony.
What to keep in mind
The article says blockchain records have functional limits, especially because they can only guarantee data integrity within the digital environment and cannot by themselves prove physical-world events. The available summary does not describe empirical testing, and it does not provide details about specific case outcomes.
Key points
- Blockchain can create reliable digital records, but technical security alone does not establish legal certainty.
- The study compares approaches in China, the U.S., the EU, France, Germany, the U.K., and Türkiye.
- Blockchain evidence is most effective for on-chain transactions and certain forms of digital recording.
- The article identifies problems with attribution, harmonised standards, and the "garbage in, garbage out" principle.
- The authors recommend admissibility criteria, standardised verification, judicial training, and coordination with UNCITRAL and EU regulations.
