Zero-Knowledge Proofs for Scalable Private Blockchains
Blockchains face a trilemma: security, scalability, and decentralization. Zero-knowledge proofs offer a path forward.
The Blockchain Trilemma
Current systems sacrifice:
- Bitcoin: Scalability (7 TPS)
- Solana: Decentralization
- Private chains: Transparency
Zero-Knowledge Solutions
ZK proofs enable:
- Verifying computation without revealing inputs
- Compressing transaction validation
- Hiding transaction details
- Trustless bridges
Our Innovations
The 7lineas ZK stack includes:
- Recursive SNARKs - Proofs of proofs
- Hardware acceleration - 100x faster proving
- Universal circuits - One setup for all
- Incremental verification - Streaming proofs
System Architecture
Layers:
- L1: Settlement and data availability
- L2: Execution with ZK proofs
- L3: Application-specific rollups
