GXChain allows users to take greater control of their personal data and creates a blockchain-based marketplace of data. Unlike centralized data centers, the GXS marketplace provides more privacy through encryption and allows users to profits from access to their data. GXChain's platform allows users to generate a unique digital identity and manage their personal data through the Inter Planetary File System (IPFS). Users can then monetize this data according to their preferences and well defined smart contracts. The network features an innovative hybrid consensus mechanism that combines Delegated Proof of Stake (DPoS) and Proof of Credit Share (PoCS).

Fetch.AI is developing a decentralized, AI optimized marketplace for data. Trading on their decentralized network will be performed by Autonomous Economic Agents (AEAs), that will execute transactions without human intervention. These agents will perform tasks, such as delivering data or providing services, and will receive Ethereum-based Fetch tokens as an incentive. Fetch.AI's Open Economic Framework (OEF) will use AI and blockchain to enable these autonomous agents to optimize trading activity in real time.

Particl is developing a privacy-focused blockchain-based marketplace. The platform will include encrypted communication tools and a native confidential currency. It will also be integrated with other cryptocurrency projects. The Particl marketplace will have confidential transactions, escrow services, and a decentralized self-governance system. Their native blockchain has a Proof-of-Stake (PoS) consensus mechanism with quantum-resistant cold-staking.
