What the study found
Blockchain can offer reliable technical records, but the article finds that technical security alone does not make blockchain evidence legally certain in civil litigation. It also reports that blockchain records have functional limits, especially when they are used to prove events in the physical world.
Why the authors say this matters
The authors conclude that integrating blockchain into evidence law requires clear rules that balance technical reliability with procedural safeguards. They also say standard admissibility criteria, verification mechanisms, judicial training, and coordination with international standards such as UNCITRAL and EU regulations are needed for more uniform use across jurisdictions.
What the researchers tested
The article uses comparative legal analysis to examine how different legal systems treat blockchain evidence. It looks at China, the United States, the European Union, and national practices in France, Germany, the United Kingdom, and Türkiye.
What worked and what didn't
The findings indicate that blockchain evidence is most effective in three situations: proving transactions carried out directly on blockchain networks, acting as an electronic detection instrument for transactions outside the network, and recording real-world events directly onto blockchain systems. The article also says problems remain, including no harmonised standards, difficulty proving attribution, the "garbage in, garbage out" issue, and the need for expert testimony.
What to keep in mind
The abstract does not describe empirical testing; it presents a comparative legal analysis. The article’s limits are also tied to scope: blockchain records can confirm integrity within the digital environment, but the abstract says they cannot by themselves prove physical-world events.
Key points
- Technical security in blockchain does not by itself create legal certainty in civil litigation.
- The article compares approaches in China, the United States, the European Union, France, Germany, the United Kingdom, and Türkiye.
- Blockchain evidence is described as most effective for blockchain-native transactions, detection of outside-network transactions, and direct recording of real-world events.
- The abstract says blockchain records can ensure integrity within the digital environment but face limits in proving physical-world events.
- The authors call for admissibility criteria, standard verification mechanisms, judicial training, and coordination with UNCITRAL and EU regulations.
