CoinRabbit & ChangeNOW Report: Open Blockchains Expose Corporate and Personal Wealth to New Risks
A new report from CoinRabbit and ChangeNOW, presented by Decrypt, argues that the transparency of public blockchains has become a critical security liability for both corporate treasuries and individual holders. The Financial Privacy in the Digital Age Report, drawing on data from TRM Labs, Chainalysis, CertiK, and Statista, details how open ledgers expose sensitive financial data and calls for a shift toward privacy-preserving infrastructure in Web3.
Why Public Ledgers Are a Liability for Businesses and Individuals
Unlike traditional bank accounts, public crypto addresses display balances, cash flows, vendor payments, and even payroll schedules to anyone with an internet connection. The report notes that competitors can monitor corporate wallets to reverse-engineer profit margins and supplier terms. With Statista estimating the average data breach cost at $4.44 million, the report argues that fully transparent ledgers leave corporate treasuries dangerously exposed.

For individual holders, the risks extend beyond financial loss. “Public blockchain transparency lets anyone audit your net worth in real time, turning private wealth into public information,” said Walter Barrett, Chief Strategy & Growth Officer at CoinRabbit. The warning is backed by data: CertiK recorded 52 verified physical extortion, or “wrench,” attacks targeting crypto holders in the first half of 2026, totaling $124.1 million in stolen funds. France accounted for 33 of those incidents, where leaks at public agencies allowed criminals to link home addresses to crypto wallets. The report also found that 30% of surveyed high-net-worth holders now pay data-removal services to hide their personal information.
Where Enforcement Actually Catches Financial Crime
The report addresses the common argument that privacy tools enable crime, acknowledging TRM Labs data showing $158 billion in illegal crypto flows in 2025, with Chinese laundering networks handling over $100 billion. However, it argues that public ledger history is rarely the decisive factor in catching criminals.

“Successful blockchain investigations rely on the combination of on-chain analysis, behavioral patterns, KYC information, exchange cooperation, stablecoin issuer interventions, and traditional investigative methods,” said Albert Quehenberger, founder of AQ Forensics. “In practice, attribution is achieved by connecting multiple sources of evidence rather than relying on blockchain transparency alone.”
Because investigators depend on regulated gateways like exchanges and fiat off-ramps, the report contends that base-layer privacy tools can protect legitimate capital without obstructing law enforcement.
Balancing Commercial Confidentiality with Regulatory Oversight
The study proposes a fundamental design change for Web3: moving from default public broadcasting toward selective, permissioned privacy. “The privacy debate starts from the wrong assumption that ordinary users must prove they have nothing to hide by exposing everything,” said Pauline Shangett, Chief Strategy Officer at ChangeNOW. “That is not how any mature financial system works.”
As the industry pushes for broader adoption, the tension between default openness and basic confidentiality remains a central debate. Developers are building tools to protect business secrets and individual wealth, while regulators continue to demand tighter oversight. How the industry balances these priorities will likely determine whether public blockchains can support widespread business and personal use.
