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.
Transcendece combines an open-source, decentralised blockchain with existing services as like AmiCloud and the indieGO-Appstore. All of them accept the Transcendence Network Token called Telos. The longterm plan is to move the cloudstorage and cloudcomputing aspects of the closed source software to the opensouce blockchain.
