According to Cointelegraph, transparency, a key feature of blockchain technology, poses challenges for its adoption in sectors such as business and medicine. Eran Barak, CEO of Midnight, a privacy sidechain for Cardano, emphasized that blockchain metadata can expose significant information about individuals or entities, making them vulnerable to identification and tracking by threat actors and data collectors.
Barak illustrated the potential risks with a hypothetical scenario involving on-chain medical records. Without privacy measures, the frequency of an individual's doctor visits could inadvertently signal health issues to external observers. Furthermore, metadata from individuals within an organization could compromise its security by offering forensic clues that help threat actors form a comprehensive understanding of their target.
The privacy concerns are exacerbated in the era of artificial intelligence, where AI can analyze heuristic clues to statistically model probable outcomes about individuals or entities. This underscores the need for enhanced data protection measures.
Paul Brody, global blockchain leader at EY, previously highlighted the necessity for privacy solutions to facilitate the integration of blockchain and Web3 applications in business operations. He noted that businesses, especially large corporations, require privacy to safeguard sensitive data related to pricing strategies and business contracts from competitors. Failure to protect such data could lead to competitive attacks or even impact global capital markets.
Avidan Abitbol, project director for the Data Ownership Protocol (DOP) privacy solution, supported this view, stressing the importance of protecting data generated from daily business activities like payments, asset holdings, and workflows. David Holtzman, a former military intelligence professional and White House adviser, warned of AI's potential to disrupt centralized information systems and privacy. He advocated for decentralizing information systems through blockchain while ensuring data privacy and security in the age of machine intelligence.
