ZKP Integration for Data Marketplace
ZKPs are seamlessly integrated into the Storage Layer to support a decentralized data marketplace, enabling secure and private transactions for AI datasets:
Operational Workflow
Data Upload
A seller uploads a dataset to IPFS, generating a CID (e.g., a SHA-256 hash of the data). The CID is registered on-chain through a custom data marketplace pallet that manages dataset metadata within Substrate's Patricia Trie structure.
Proof Generation
The seller produces a ZKP (approximately 300 bytes) to attest to specific dataset properties—such as its size or content quality—without revealing the data itself. This proof, generated using zk-SNARKs through Substrate's off-chain workers, ensures computational integrity while maintaining privacy.
Verification
The buyer verifies the ZKP in 2 milliseconds through either EVM pre-compiled contracts or native Substrate verification pallets, confirming the dataset's attributes align with their requirements. The verification process integrates with Substrate's weight-based execution model for efficient resource management.
Access and Integrity
Upon successful verification, the buyer retrieves the dataset using the CID through coordinated off-chain workers, with the ZKP affirming its integrity. The transaction is recorded on-chain through the marketplace pallet, ensuring transparency and auditability.
The Proof Behind Champions
Those who compete at the edge of human precision now back the technology that defines digital truth.
