The differences between ZK compression and State Compression

The main differences between ZK compression and State Compression are:

1. Technical Approach:
   • State Compression: A basic technology that compresses data for storage.
   • ZK Compression: Uses State Compression techniques but adds Zero-Knowledge (ZK) proofs to ensure data integrity.
2. Security Level:
   • State Compression: Provides basic data compression.
   • ZK Compression: Offers enhanced security by using Zero-Knowledge proofs.
3. Cost Reduction:
   • State Compression: Reduces costs, but not as dramatically as ZK Compression.
   • ZK Compression: Achieves more significant cost reductions. For example, an airdrop to 1 million users costs about $50, compared to $110 with State Compression.
4. Implementation:
   • State Compression: A relatively simple compression technique.
   • ZK Compression: A more complex technology that incorporates Zero-Knowledge proof mechanisms.
5. Scalability:
   • State Compression: Improves scalability, but not to the extent of ZK Compression.
   • ZK Compression: Provides advanced scalability, enabling scaling to millions of users.

In essence, ZK Compression extends the concept of State Compression by incorporating Zero-Knowledge proofs, resulting in a technology that offers enhanced security, substantial cost reductions, and superior scalability. It’s an advanced version of State Compression that provides additional benefits and capabilities.
