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.
PIRATE (ARRR) is the best of Zcash (ZEC) combined with the best of Monero (XMR) and secured by Komodo's (KMD) Delayed-Proof-of-Work (dPoW) It’s a forced Shielded-transactions (z-transactions) only blockchain, meant for completely anonymous transactions. PIRATE is mined into a transparent address, but can only go into a shielded address from there. PIRATE is an independent blockchain built using the Komodo Platform assetchains. PIRATE is feature complete for its goal: complete anonymity.
