DxChain is a blockchain-based network that provides a solution for running machine learning algorithms on big data sets, while preserving privacy and security. DxChain's architecture consists of three layers with specific functions related to storing data and executing operations. The DxChain network is powered by the Ethereum based DX token.

Enigma aims to bring greater utility to blockchain by increasing privacy. The Enigma protocol introduces private smart contracts called "secret contracts"​, that enable computations on encrypted data, and use the blockchain infrastructure for payment distribution and other functions. Enigma is taking on one of the central problems facing blockchain, maintaining data privacy while meeting the rapidly growing scaling requirements of decentralized networks. Enigma tries to solve this problem by introducing a second layer network for computations. By using secret contracts that allow nodes to process data, sensitive proprietary data can be protected, while maintaining the other benefits of storing data on a blockchain.

Blockstack is developing a decentralized computing platform that enables users to better control their data and identity. Blockstack's open-source software is designed to be a decentralized computing network for DApps. Applications built on Blockstack allow users to maintain direct ownership of their internet assets and ensure privacy for users. Blockstack Apps use private data lockers and blockchain-based security mechanisms to protect personal user data. The network uses an innovative consensus mechanism called Proof of Transfer, that rewards participants in a non-native currency for helping to secure the network.
