Monero is a decentralized public ledger protocol whose focus is on increased privacy. It was created in 2014, with the goal of establishing a privacy focused blockchain that would allow users to send and receive transactions anonymously, and not pseudo-anonymously, like Bitcoin.
Monero uses an obfuscated public ledger that prevents anyone from determining the source, destination, or amount of payments. Unlike many other cryptocurrencies, payments and account balances on Monero remain entirely hidden. This is one reason that XMR, the Monero currency, has attracted some users that are involved with illicit activities.
Monero uses a Proof of Work consensus mechanism that requires less computing power from miners than Bitcoin does. Because of this, mining Monero has become an alternative source of revenue for some websites and apps. .

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.

DAPS, which stands for Decentralized, Anonymous, Payment, System, is developing a privacy focused cryptocurrency. It is currently an Ethereum-based token, but they are planning on releasing their own blockchain to host the project. DAPS uses the Harpocrates protocol to allow users to send and receive DAPS tokens anonymously. DAPS was previously associated with PeepCoin project, but a disagreement between the developers of the project, ended plans for an airswap of the two privacy focused cryptocurrency projects.
