The [[ZKP/Data Marketplace/Intro|marketplace]] leverages the ZKP Blockchain's [[ZKP/ZKP Base Layer/ZKP Blockchain/Technical Build Consensus Layer/Consensus Model|hybrid consensus mechanism]], combining [[Proof of Intelligence (PoI)]] and [[Proof of Space (PoSp)]] integrated with BABE+GRANDPA consensus. PoI uses mathematical operations with deterministic outputs for computational validation, including matrix operations (up to 100×100 dimensions), element-wise activation functions for vectors up to 1,000 elements, and simple feedforward inference for models up to 10^5 parameters. PoSp ensures data availability through cryptographic storage proofs managed by custom [[Substrate]] pallets [79].
