At the recent Consensus Miami conference, industry leaders from Moody’s Ratings and ChangeNOW explored the challenges of maintaining user privacy while ensuring transaction transparency in public blockchains. They proposed that a hybrid blockchain architecture could effectively address these conflicting needs.
Public blockchains are designed for transparency, allowing transactions to be traced and audited. However, this visibility can compromise user privacy, a core principle of cryptocurrency. Traditional compliance systems often require identifying users, which contradicts the notion of anonymous transactions.
Rajeev Bamra, global head of strategy for digital economy at Moody’s, highlighted the potential of an on-chain intelligence layer that integrates both hybrid blockchain architecture and wallet-address-level monitoring. This system aims to distribute responsibilities across various components, enabling private networks to offer accountability while public chains enhance liquidity. Bamra noted that the institutional digital finance market is currently valued at approximately $35 billion, with significant growth observed in the past year and a half.
Bamra emphasized that the future of blockchain will not be strictly public or private but will likely be a combination of both. He stated, “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 ChangeNOW, echoed the importance of user privacy, asserting that Bitcoin was originally intended as a semi-anonymous digital currency. ChangeNOW, which does not mandate KYC (Know Your Customer) checks, collaborates with anti-money laundering (AML) providers and blockchain forensics firms to monitor transactions at the wallet level without linking them to individual identities.
Shangett explained that when law enforcement requests transaction data, ChangeNOW can provide information without revealing the identities of users involved. This approach allows the platform to facilitate registration-free swaps while ensuring compliance with regulatory requirements.
On the topic of regulation, Bamra pointed out that frameworks like the European Union’s Markets in Crypto-Assets Regulation and the U.S. GENIUS Act share similar goals regarding asset quality and liability, yet differ significantly in their implementation details. He remarked, “We think there is regulatory convergence in intention, but there’s fragmentation in reality or in execution.”
Shangett concluded by addressing regulatory liability, suggesting that responsibility should rest with those involved in the emission of assets rather than their transmission. She stated, “The agents who should be held liable for the regulatory frameworks and the adoption thereof are agents who are dealing with emission and not transmission.”
At the Consensus Miami conference, experts discussed the tension between transparency and privacy in blockchain transactions. They proposed a hybrid architecture to balance these aspects, emphasizing the importance of user anonymity while ensuring compliance with regulations.
