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.
Amoveo (VEO) is a highly scalable proof-of-work blockchain driven by its community and aimed for prediction markets, investment and insurance contracts, and various derivatives, such as stable coins. Amoveo is a blockchain meant for enforcement of investment and insurance contracts. Amoveo contracts are enforced using state-channels. This means fees are low, contracts are nearly instant and can support a global audience. Amoveo has oracle technology. Amoveo can learn facts about our world and enforce the outcome of contracts that are governed by these facts. This, for example, enables you to bet on the price of Amazon shares. The variables that define how to participate in Amoveo can be modified by the Amoveo community using a built-in process. This way Amoveo will always stay optimally tuned to produce the best results.
