🔐 Deep Defense Guide | How to Build a 'Physical-Level' Security Barrier for Your Multi-Signature Wallet?
Warning of $27 million loss: As attacks escalate, defenses must penetrate into physical and operational levels.
✅ Build a 'Trust No Device' Multi-Signature System
1. Absolute purity of key generation
Each multi-signature private key should be generated on a brand new, offline device that has never connected to the internet (or a hardware wallet).
After generation, immediately permanently destroy any network hardware modules (such as Wi-Fi/Bluetooth chips) on that device, or permanently convert it to a 'signature-only machine'.
2. Physical isolation of the signing process
When signing, use offline QR codes or SD cards to transfer unsigned transaction data between the signing device and the networked transaction building device.
It is absolutely forbidden to use USB cables for direct connections or any network protocols that may transmit files.
3. Extreme control of devices and environment
Dedicated devices: The computers or mobile phones used for signing should only have the signing software and necessary system components installed; no other software should be installed, and absolutely no web browsing or email processing should occur.
Physical isolation: The room where the signing devices are stored should implement strict physical access control and network shielding.
💎 Ultimate Principle
For large assets, the security goal is not 'difficult to break', but rather 'physically impossible to be remotely breached'. Elevate your multi-signature scheme from 'software security' to 'hardware and process security' levels.
