Introduction to Proving Systems in Blockchain
Proving systems serve as the backbone of blockchain ecosystems, enabling secondary "rollup" networks to verify transactions on base chains like Ethereum. Polygon's latest innovation, Plonky3, builds upon its predecessor Plonky2 (released in 2022) with enhanced flexibility and developer-centric features.
Key Features of Plonky3
- Open-Source Accessibility: Released under MIT and Apache licenses, fostering community collaboration.
- Modular Design: Functions as a toolkit for developers to create custom virtual machines using zero-knowledge (ZK) cryptography.
- Performance Improvements: Addresses limitations of Plonky2, offering broader applicability and efficiency.
"Plonky3 represents the future direction of Polygon’s technology," said Daniel Lubarov, Polygon co-founder.
The Role of Zero-Knowledge Cryptography
ZK proofs are critical for:
- Transaction Validation: Summarizing off-chain transactions for base-layer verification.
- Scalability: Enabling faster, cheaper rollups without compromising security.
- Privacy: Allowing verification without exposing sensitive data.
Polygon has heavily invested in ZK tech, including acquisitions of Hermez, Mir, and Toposware—leading teams in ZK cryptography.
