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.
Our vision is to create a global exchange using Ethereum blockchain, where everyone on this planet has the opportunity to buy and sell mobile bandwidth in any country just like you buy foreign currencies on FOREX.
