Binance founder Changpeng Zhao said the transparency of public blockchains is holding back crypto payments. In his view, many companies are reluctant to use cryptocurrencies for payroll and operating expenses because onchain transactions can expose sensitive financial information.
Zhao said this problem is especially clear on networks such as Bitcoin and Ethereum, where transaction records are visible to anyone. Wallet addresses may not carry real names, but payment patterns, transfer timing, and fund movements can still be linked back to individuals or businesses. For companies, that turns a technical feature into a practical barrier.
Payroll onchain can expose compensation data
Zhao used payroll as a simple example. If a company pays employees onchain, outside observers may be able to see how much each worker received. In traditional banking systems, salary data is usually treated as private. On a public ledger, that same information becomes observable, and Zhao said this discourages firms from using crypto for internal payments.
He also pointed to personal security concerns. In earlier remarks on the All-In Podcast with investor Chamath Palihapitiya, Zhao warned that transaction visibility could leave users more exposed to theft or scams. The risk is higher for public figures, whose balances and income may become easier to track.
Visible payment flows can reveal supplier links and business patterns
Others in the industry raised similar concerns. Avidan Abitbol, a former business development specialist at the Kaspa project, said companies worry that blockchain payment histories can reveal operational data. That can include supplier relationships, revenue patterns, and strategic partnerships, all of which may be valuable to competitors.
Abitbol added that the issue goes beyond commercial intelligence. Publicly visible payment flows can also support targeted fraud and phishing attempts. Attackers can watch for large transfers and study predictable payment behavior. In his view, that exposure is one reason institutions remain cautious about deeper participation in Web3 systems.
AI makes public blockchain data easier to mine
The privacy debate has been part of crypto since its early days, when cypherpunk ideas shaped the push for encryption and protection from surveillance. Now that discussion is taking on new urgency as artificial intelligence improves the ability to process public information at scale.
Eran Barak, former CEO of Shielded Technologies, previously said AI tools can analyze blockchain records together with data from other sources. He argued that detailed financial profiles can be built even without private access. That is one reason privacy tools such as zero-knowledge proofs are drawing more attention: they aim to conceal transaction details while still allowing payments to be validated onchain.
