The rapid development of quantum computing poses serious threats to existing cryptographic systems. Experts predict that within the next 10-20 years, large-scale quantum computers may break the currently widely used ECDSA and RSA algorithms. Vorn Network has formulated a comprehensive post-quantum security migration strategy to ensure long-term network security:Phase 1: Preparation and Standardization Technical preparation lays the foundation for future smooth transitions:
Protocol layer reservation: Reserve variable-length signature fields in transaction structures, design extensible cryptographic algorithm identifiers in block headers, ensuring future upgrades without hard forks
Algorithm evaluation: Closely follow NIST post-quantum cryptography standardization process,focusing on evaluating performance and security of algorithms like CRYSTALS-Dilithium
Performance optimization: Collaborate with cryptography research institutions to optimize postquantum algorithm implementations for blockchain scenarios, controlling signature verification time within acceptable ranges
Each transaction contains both ECDSA signature (maintaining backward compatibility) and post-quantum signature (providing quantum resistance)
Validators must verify both signatures are valid; transaction is invalid if either signature fails
Even if quantum computers can break ECDSA, post-quantum signatures still protect asset security
Coexisting account types:
Traditional accounts: Only use ECDSA, suitable for conservative users
Hybrid accounts: Use both signature types, providing transition period protection
Post-quantum accounts: Only use post-quantum cryptography, prepared for the future
Dynamic fee adjustment: Additional computational cost of post-quantum signatures reflected through slightly higher gas fees, incentivizing but not forcing user migration
Phase 3: Complete Migration Achieve comprehensive transition after ecosystem is fully prepared:
Mandatory migration trigger conditions:
Over 80
Quantum computers pose actual threat to ECDSA (such as practical implementation of Shor’s algorithm)
Community reaches consensus through governance voting
Migration execution plan:
Set deadline after which newly created accounts only support post-quantum cryptography
Provide one-click migration tool, users transfer assets from old accounts to new accounts through single transaction
Establish custody mechanism for dormant accounts still using traditional cryptography to protect their assets
Ecosystem support:
Wallets, browsers, development tools fully support post-quantum cryptography
Provide detailed migration guides and technical support
Establish migration fund to subsidize user migration costs
This phased migration strategy ensures Vorn Network can calmly respond to quantum computing threats, protecting user asset security while minimizing impact on existing ecosystems, achieving smooth transition to the post-quantum era.
