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.

Beam is developing a confidential cryptocurrency that uses the Mimblewimble protocol. It will have a Proof-of-Work (PoW) consensus mechanism, and will enable private transactions that can be audited for compliance purposes.

Grin Coin is a community driven blockchain project that aims to create a lightweight mimblewimble blockchain that will enable anonymous transactions. Grin has a Proof-of-Work consensus mechanism. Transactions are executed while hiding addresses and amounts.
