Loki combines a private transaction network based on Monero with economically incentivised service nodes to create a trustless quorum based networking protocol. This protocol allows anyone to route small packets of data in an anonymous and decentralised way. The front end applications that use this packet routing system are private-by-design, and are known as Service Node Apps “SNApps”; the first of which is the Loki Messenger - a decentralised, anonymous and private messaging service. Check out Coinbureau for the complete review of Loki Coin.
Dusk Network is a high throughput permissionless blockchain aimed at providing privacy, programmability and auditability. Dusk Network is currently in the Testnet phase and is a blockchain protocol for easy deployment of programmable zero-knowledge dApps, thus becoming the backbone of an open, permissionless and global privacy-oriented dApp ecosystem. Dusk Network aims to remove technical barriers that have undermined mainstream issuance and trading of security tokens. Compliance, auditability and privacy are built into the open, permissionless Confidential Security Token-standard (XSC).
