Blockchain can enhance news provenance tracking by implementing immutable timestamping and source verification on distributed ledgers. By anchoring digital content on a blockchain, journalists can create tamper-proof records that prove authenticity and integrity at specific points in time, ensuring that any modifications are detectable[6]. This process builds a trustworthy framework for verifying the origins of news content, crucial for battling misinformation and deepfakes in today's digital landscape[2].
Pilot projects are underway to assess this technology's impact on media integrity; however, limitations such as scalability and regulatory acceptance remain challenges[2][6]. As organizations seek to improve transparency in news reporting, blockchain may revolutionize how source verification is conducted[6].
