The [[ZKP/Data Marketplace/Intro|Data Marketplace]] builds upon the [[ZKP/ZKP Base Layer/ZKP Blockchain/High Level Overview|ZKP Blockchain L1 Substrate infrastructure]] with the following key elements: ## [[ZKP/Data Marketplace/Tokenized Datasets/Comprehensive Mechanisms of Tokenized Datasets|Tokenized Datasets]] Transform data into tradeable digital assets, using Substrate's native token standards for divisible datasets and unique asset pallets for non-fungible datasets [83]. This enables data creators to monetize contributions while maintaining ownership through Substrate's account system. ## [[ZKP/Data Marketplace/Tokenized Datasets/Tiered Access Control|Granular Access Control]] A multi-tiered permission system authenticated through ZKPs governs access based on token ownership, implemented through custom Substrate pallets. Tiers range from free metadata previews (Tier 0) to full dataset access (Tier 5), with ZKPs enabling eligibility verification without exposing sensitive user details [77]. ## Quality Assurance Framework A multi-layered approach combining reputation systems managed through native pallets, [[Proof Pods in the Data Marketplace|validation networks]], and automated audits ensures [[ZKP/Data Marketplace/Decentralized Governance/Dataset Submission and Preliminary Verification|data quality and reliability]] [79]. ## [[ZKP/Data Marketplace/Decentralized Governance/Decentralized Governance via Data DAOs|Decentralized Governance]] Data DAOs oversee shared datasets using ZKP-secured voting mechanisms implemented through Substrate's democracy pallet, enabling transparent, democratic management of marketplace policies [84].
