Blockchain Evidence In Criminal Trials
What is Blockchain Evidence?
Blockchain technology is a decentralized digital ledger that records transactions in a secure, tamper-proof manner.
Blockchain evidence refers to data or transaction records stored on a blockchain that can be presented in court.
This can include cryptocurrency transaction histories, smart contract records, timestamps, or any data immutably stored on the blockchain.
Such evidence is particularly relevant in cases involving cryptocurrency fraud, money laundering, digital contracts, and cybercrime.
2. Challenges of Blockchain Evidence in Criminal Trials
Authentication: Proving that the blockchain data is genuine, untampered, and linked to the accused.
Chain of custody: Demonstrating that the evidence has been preserved securely.
Technical complexity: Judges and lawyers must understand blockchain technology.
Legal admissibility: Courts must decide if blockchain evidence meets standards under the Evidence Act.
3. Legal Framework for Admissibility
Under the Indian Evidence Act, 1872:
Section 65B: Electronic records are admissible if accompanied by a certificate authenticating the data.
Blockchain evidence, being electronic, must comply with this for admissibility.
Courts also apply general principles of relevance, authenticity, and reliability.
Landmark Cases and Judgments on Blockchain Evidence
