Open Blockchains Expose Corporate and Personal Wealth to Security Risks

A new report by CoinRabbit & ChangeNOW reveals that open blockchains leave corporate and personal wealth vulnerable to security liabilities. The study, presented by Decrypt, highlights the risks of public ledger transparency in exposing critical data for both business and personal assets.

According to the Financial Privacy in the Digital Age Report, transparent ledgers allow competitors to track vendor payments, pricing, and balances, impacting 36% of board members who see data leaks as their top operational threat. This is particularly concerning for companies that hold funds on-chain, as public crypto addresses show cash flows, vendor details, and balances to anyone with an internet connection.

The report notes that while open ledgers make auditing simple, they create major liabilities for those holding funds on-chain. In the first half of 2026, CertiK recorded 52 verified physical extortion attacks targeting crypto holders, totaling $124.1 million in stolen funds.

However, critics often argue that privacy tools encourage crime, pointing to TRM Labs data showing $158 billion in illegal crypto flows in 2025. However, research shows that public ledger history is rarely what catches criminals. Instead, law enforcement relies on centralized touchpoints such as exchange KYC databases and fiat off-ramps.

The study calls for a simple change in Web3 design: moving away from default public broadcasting toward selective, permissioned privacy. This would protect legitimate capital without blocking law enforcement. As crypto aims for broader adoption, the choice between default openness and basic confidentiality remains a key debate.
