Transparency in public blockchains facilitates transaction tracing, auditing, and enforcement; however, this visibility can impinge upon user privacy. Traditional compliance mechanisms typically ensure accountability by identifying individuals, yet this approach contradicts one of the foundational tenets of cryptocurrency: the ability to conduct transactions without inherently revealing personal identity.
Panelists at CoinDesk’s Consensus Miami conference highlighted that these tensions are increasingly manageable through an onchain ‘intelligence layer’ integrating hybrid blockchain architecture with wallet-address-level surveillance. The concept involves distributing responsibilities across system components, allowing private permissioned networks to provide institutions with accountability and credibility, while public permissionless chains offer liquidity. Blockchain-forensics tools assist platforms in monitoring transactions at the wallet address level without automatically associating users with real-world identities.
Rajeev Bamra, Moody’s Ratings’ global head of strategy for digital economy, noted that traditional intelligence layers respond to three inquiries: ‘Who is it? What are they doing? And can I trust the record?’ In conventional finance, these queries have been addressed by banks, custodians, clearinghouses, and credit-rating agencies. Bamra estimated the institutional digital-finance market at approximately $35 billion today compared to over $200 trillion in annual clearing-house flows within traditional finance, noting a growth rate of ‘over 100 or 150%’ in the past 18 months. He predicted that blockchain architecture will likely be hybrid rather than exclusively public or private, stating, ‘Private permission networks are going to offer the accountability, the credibility aspect,’ while ‘the public permissionless brings the liquidity which the private permissions don’t.’
Pauline Shangett, chief strategy officer at non-custodial exchange ChangeNOW, emphasized user privacy. She remarked that Bitcoin was originally intended as a semi-anonymous digital currency. ChangeNOW, which does not enforce KYC by default, collaborates with AML providers and blockchain forensics firms to monitor transactions at the wallet address level. Shangett explained that this infrastructure enables mapping of addresses rather than individuals passing funds through their system.
When law enforcement requests information from ChangeNOW, Shangett stated the company provides transaction data without revealing personal identities. This approach allows for registration-free swaps while maintaining internal accounting systems and cooperating with authorities on illicit transactions. Regarding regulation, Bamra noted that cross-border frameworks like the EU’s Markets in Crypto-Assets Regulation and the U.S. GENIUS Act pose similar fundamental questions about asset quality, segregation, and liability but differ significantly at the specifications level. He mentioned, ‘We think there is regulatory convergence in intention, but there’s fragmentation in reality or in execution.’
Shangett concluded with a perspective on regulatory liability, suggesting that responsibility should lie with those involved in emission rather than transmission of assets.
