Hybrid Blockchain Compliance Balances Privacy and Regulation in Crypto

Public blockchains offer unmatched transparency, making crypto transactions easier to trace, audit, and monitor. However, this openness often raises concerns about user privacy. Industry leaders at CoinDesk’s Consensus Miami conference said the future of crypto compliance may rely on a new “intelligence layer” that combines blockchain analytics, hybrid blockchain architecture, and wallet-level monitoring without exposing personal identities.

Rajeev Bamra, global head of strategy for digital economy at Moody’s Ratings, explained that traditional financial systems answer three core questions: who is involved, what activity is taking place, and whether the record can be trusted. In conventional finance, these responsibilities are handled by banks, custodians, and clearinghouses. In digital finance, blockchain infrastructure is evolving to serve similar purposes while preserving decentralization.

Bamra estimated the institutional digital-finance sector is currently worth around $35 billion, compared to over $200 trillion in annual clearing-house flows in traditional finance. He noted that the market has grown more than 100% in the past 18 months. According to him, the future of blockchain will likely be hybrid, combining private permissioned networks for accountability and credibility with public permissionless chains that provide liquidity and open market access.

Pauline Shangett, chief strategy officer at non-custodial exchange ChangeNOW, emphasized the importance of privacy in crypto. She said Bitcoin was originally designed as semi-anonymous digital cash and argued that compliance systems should not automatically require personal identification.

ChangeNOW uses AML providers and blockchain forensics tools to monitor transactions at the wallet-address level instead of linking activity directly to real-world identities. Shangett explained that the platform can cooperate with law enforcement by sharing transaction data without revealing user identities, allowing registration-free crypto swaps while still addressing illicit activity.

The discussion also touched on crypto regulation. Bamra said regulations such as the European Union’s MiCA framework and the U.S. GENIUS Act share similar goals around asset quality and liability but differ significantly in implementation. Shangett concluded that regulatory responsibility should focus more on entities issuing assets rather than those simply transmitting transactions.
