Blockchain technology's immutable and transparent nature makes it an attractive option for creating tamper-proof records. Courts worldwide are beginning to recognize blockchain evidence, but challenges remain.

Advantages of blockchain evidence:
- Immutability and tamper resistance
- Transparent audit trails
- Cryptographic verification
- Reduced reliance on intermediaries

Legal challenges include:
- Authentication requirements
- Hearsay rules and exceptions
- Technical complexity for judges and juries
- Cross-border evidence issues

Recent cases have shown courts' willingness to accept blockchain evidence when properly authenticated. The key is establishing the reliability of the blockchain system and the accuracy of the data input.

As blockchain adoption grows, we can expect more standardized approaches to blockchain evidence, potentially including specialized rules and procedures.
