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.

Golem is a decentralized computing network that allows users to be paid for their unused computing power. Golem is an important project that aims to create a super computer that anyone can access.
The Golem network is powered by the Ethereum-based GNT token.
