Threat Model and Key Protections

...

Security and Privacy

The marketplace operates under a defined threat model addressing four key security concerns:

Core Security Framework

Data Integrity

PoSp mechanisms implemented through custom pallets ensure dataset availability and tamper resistance through cryptographic storage proofs, with 99.9% uptime as established in the base layer specifications.

Access Control

zk-SNARKs provide cryptographic verification of access rights through the verification infrastructure without revealing user balances or permissions, maintaining privacy while ensuring security.

Smart Contract Security

Contract-level protections follow established best practices for EVM pallet environments, including access controls and event logging through the event system for transparency.

Privacy Guarantees

Beyond basic encryption, the system's zero-knowledge architecture ensures that sensitive information remains protected during verification processes, addressing the fundamental privacy challenges of decentralized data sharing.

The security framework integrates with the marketplace's governance model through the democracy pallet, allowing Data DAOs to establish and enforce quality standards while maintaining the system's cryptographic guarantees.

This multi-layered approach creates a balanced security architecture that protects both individual participants and the ecosystem as a whole.oth individual participants and the ecosystem as a whole.
