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.
Celer Network is a coherent technology and economic architecture to enable Internet-scale public blockchains through off-chain scaling techniques. It can scale out to billions of transactions per second, and will fully unleash the power of blockchain and decentralized applications.
