Loki is developing a privacy-focused blockchain that will enable private transactions and decentralized communication. The Loki blockchain will be complemented by Lokinet and SNApps. Lokinet will use onion routing to allow users to access the internet privately without revealing their IP address. SNApps are web applications that will be located inside the Lokinet, and will be resistant to censorship. The Loki network is powered by the LOKI coin. It has a Proof-of-Work (PoW) consensus mechanism. Service nodes, on the network, are paid to process transactions and route the network's traffic and messages.

Horizen, formerly called ZenCash, is a cryptocurrency focused on privacy. Horizen has an end-to-end-encryption system with zero-knowledge technology, that allows for anonymous transactions and messaging.
The company suffered a 51% attack in June, 2018 and has since re-branded as Horizen. Horizen hopes to combine anonymous transactions and messaging with an emphasis on community governance.
