Dr. David Uzker, a former U.S. Treasury technology expert, has raised alarms about the centralization of supposedly decentralized crypto assets. According to Uzker, billions of dollars in digital assets are controlled through private servers, hidden admin keys, and corporate entities, posing systemic risks. His research indicates that 60% to 75% of daily digital asset revenues are linked to centralized tokens like USDT and USDC. Uzker highlighted that vulnerabilities in decentralized finance (DeFi) have led to over $3 billion in user losses in 2025 alone. He cautions that if these hidden control points fail, the value of these assets could disappear overnight. Uzker calls for stringent crypto regulation and transparent disclosure standards to avert a potential collapse of trust at the code level.
