ARPA is a Secure Computation Network Compatible With Blockchains They propose a blockchain-based secure computation network of Multi-party Computation (MPC). ARPA cryptographically enables private smart contract, unprecedented data-at-use privacy protection, as well as scalable computational sharding.
FNKOS is a fog computing-based blockchain operating system designed to make the best use of the edge computing resources such as idle hardware network and storage resources. The fog blockchain was built on the basis of a PoC (Proof of Contribution) consensus algorithm: nodes get FNKOS incentives according to their contribution in the fog blockchain based on network flow, storage volume, computational capacity.
