Insufficient privacy on public blockchains is increasingly viewed as a structural barrier to wider crypto adoption, with industry leaders arguing that full transparency may be hindering both retail payments and institutional participation.
Changpeng Zhao, co-founder of Binance, recently said that stronger privacy features could be critical to unlocking mainstream crypto payments. While blockchain transparency is often promoted as a breakthrough feature that enhances trust and accountability, Zhao suggested it can also discourage practical use when sensitive financial data is exposed.
Because most public networks allow wallet balances and transaction histories to be tracked, routine activities — such as payroll — could reveal confidential information. Zhao noted that if companies pay employees in crypto on-chain, outside observers may be able to see compensation details simply by identifying wallet addresses.
Institutional executives expressed similar concerns during a panel discussion at CoinDesk’s Consensus conference in Hong Kong. Fabio Frontini, CEO of Abraxas Capital Management, emphasized that discretion is essential for large financial transactions.
According to Frontini, transparency should not equate to unrestricted visibility. While transactions must remain auditable, access to detailed information should be limited to authorized participants rather than openly available to the public.
The conversation comes as traditional financial instruments begin migrating onto blockchain infrastructure. In December, JPMorgan Chase structured a $50 million commercial paper issuance for Galaxy Digital on the Solana network. The deal, which used Circle’s USDC stablecoin for settlement and involved participation from Coinbase Global and Franklin Templeton, highlighted the efficiency gains possible with tokenized debt.
However, it also underscored institutional hesitation around operating on fully transparent public chains.
Emma Lovett, credit lead for the Markets Distributed Ledger Technology team at JPMorgan, said institutions need assurances that their wallet addresses and transaction histories cannot be easily traced. Without such protections, she indicated, large-scale asset migration to public blockchains is unlikely.
Thomas Restout, CEO of institutional liquidity provider B2C2, added that privacy alone is not enough. Institutions also require execution certainty and trusted infrastructure capable of handling transactions at massive scale. Major financial firms, he noted, must be confident that systems can support operations involving billions — or even trillions — of dollars.
Until blockchain networks can balance transparency with confidentiality and deliver institutional-grade reliability, broader adoption by both everyday users and Wall Street firms may remain constrained.
