## Browse Metadata Access [[ZKP/Data Marketplace/Tokenized Datasets/Comprehensive Mechanisms of Tokenized Datasets|dataset]] information at [[ZKP/Data Marketplace/Tokenized Datasets/Tiered Access Control|Tier 0 without token requirements]], allowing relevance evaluation before purchase through the query interface. ## Verify and Request Access Use [[ZKP/Data Marketplace/Technical Basis/Cryptographic Foundations/zk-SNARKs and Privacy Framework|ZKPs to prove token holdings]] without revealing exact balances, with verification costing ~200,000 weight equivalent through the verification infrastructure [82]. Specify access duration and level through smart contracts or native pallets. ## Access and Download Data Retrieve datasets from [[ZKP/Data Marketplace/High-Level Overview/Off-Chain Storage with IPFS|IPFS]] using [[ZKP/ZKP Base Layer/ZKP Blockchain/Storage Layer/On-Chain Metadata Storage|on-chain content identifiers (CIDs)]] stored in Patricia Tries, with [[Proof of Space (PoSp)]] ensuring availability [87]. ## Utilize Data with Privacy Assurance Use datasets for intended purposes with [[ZKP/ZKP Base Layer/Core Concepts/Zero-Knowledge Proofs|ZKPs]] verifying legitimate access through the verification system and [[Proof of Intelligence (PoI)]] validating dataset attributes [77,79].
