CZ Says Lack of Privacy Hurts Crypto Payments

They warn that fully transparent blockchains can expose sensitive financial data, corporate relationships, and even create physical security risks, which may intensify as AI tools become more capable of analyzing public transaction data. While transparency supports trustless verification, critics say stronger privacy protections are essential if companies and institutions are to confidently embrace crypto for everyday operations.

Privacy Is Key to Crypto Growth

Concerns over on-chain transparency are resurfacing as people argue that the lack of transactional privacy is a major obstacle to crypto adoption, particularly for payments and everyday business use. Changpeng Zhao, co-founder of Binance, recently explained that without stronger privacy protections, companies and institutions will stay hesitant to use blockchain networks for routine financial operations.

Zhao pointed out that the transparent nature of most public blockchains makes corporate financial activity easily traceable. If a company were to pay salaries on-chain, for example, anyone could analyze wallet addresses and potentially determine how much employees are earning. 

In his view, this level of openness may be acceptable for decentralized verification but becomes problematic when applied to payroll, vendor payments, and other sensitive business transactions. He also previously raised physical security concerns by arguing that publicly visible balances and transaction histories could expose individuals and organizations to risks ranging from targeted scams to personal threats.

The new focus on privacy resembles the original cypherpunk ethos that underpinned the early development of cryptocurrencies. Cypherpunks championed encryption and peer-to-peer systems as tools to protect individuals from surveillance and centralized control. While blockchain transparency was initially celebrated as a way to ensure trustless verification, critics now argue that total openness may actually undermine practical adoption in commercial settings.

Avidan Abitbol, who was formerly involved in business development for the Kaspa cryptocurrency project, said that transaction data can reveal far more than simple payment flows. Corporate wallets can expose operational patterns, supplier relationships, and even provide insight into a company’s financial health. Competitors analyzing on-chain data could potentially gain strategic advantages, while malicious actors might use this information to identify targets for fraud or corporate espionage.

The risks are expected to intensify as artificial intelligence tools become more sophisticated. Eran Barak, former CEO of privacy firm Shielded Technologies, warned that AI systems can aggregate and analyze large volumes of publicly available blockchain data to uncover patterns that might otherwise go unnoticed.

While public ledgers promote accountability and trustless verification, excessive openness may deter the very institutions and enterprises that advocates hope to onboard.
