Private Keys Are a Single Point of Failure: Security Advisor Gideon Cohen Warns MPC Technology Is Now the Only Defense for Institutional Custody

LOUISVILLE, Ky. - Dec. 9, 2025 - PRLog -- Gideon Cohen, Founder of blockchain security auditing giant Halborn and Security Advisor to SQHWYD GLOBAL Ltd., issued a stern warning today: in an age of industrialized hacking, traditional single-private-key wallets are no longer safe.

Cohen cited the May 2024 DMM Bitcoin hack, which resulted in a loss of approximately $305 Million in Bitcoin. "If you are betting hundreds of millions of dollars in assets on a single string of characters, that in itself is a massive risk," Cohen stated bluntly. As an expert who has secured billions in DeFi assets, he assisted SQHWYD in building a custody system based on MPC (Multi-Party Computation).

Under this architecture, a private key never exists in its entirety. Instead, it is split into multiple cryptographic shards, distributed across different physical and network environments. A transaction can only be executed when multiple authorized parties sign simultaneously, thereby completely eliminating single points of failure. Cohen emphasized that SQHWYD's security strategy is "Defense-in-Depth," combining MPC technology with 24/7 active threat intelligence monitoring and regular Red Team/Blue Team drills. He added, "In this era of Zero Trust, security is not a feature; it is a continuous state of war. SQHWYD's architecture is designed precisely to win this war."
