Launched in Jun 2014, CLOAK is a provider of Open Source blockchain solutions using ENIGMA® technology, which reportedly helps to make transactions completely confidential. The technology is designed to be decentralized, reliable, secure, and scalable. It is based on Proof Of Stake, which was designed to reduce operating costs and carbon footprint.

Cloakcoin uses onion routing enabled by default with ENIGMA® technology. This, coupled with CloakShield® function, reportedly provides end-to-end encryption and offers direct and secure communication that allows nodes to evade traffic analysis. Combined with ENIGMA®, Cloakcoin aims to offer a high level of confidentiality that uses up to 25 jumps with symmetric RSA encryption and ECDH key exchange. 

Anyone can generate Cloakcoin with annual interest rates of 6%.

Cloakcoin aims to allow any computer or smartphone user to participate in the cryptomarket with complete security and without the fear of unwanted hacking or multi-channel spying activity.

Peercoin, also known as PPC or Peer-to-Peer Coin, was created by Sunny King and his team and launched in August 2012. It is the first blockchain to implement Proof-of-Stake consensus.

The primary inspiration behind the creation of Peercoin was to address a number of perceived shortcomings of Bitcoin, including energy efficiency, security and sustainability, decentralization and long-term viability.

Essentially it was designed as an enhanced replacement for Bitcoin. As such, it was originally forked from Bitcoin and uses the same UTXO style blockchain. However, Peercoin's code was modified to introduce Proof-of-Stake as its primary consensus protocol. The next section explains how this makes for a better blockchain.

Given that Peercoin uses most of the same code, it can easily port new features from Bitcoin and utilize any of the supporting infrastructure, including tech advancements like Taproot or Lightning Network. Peercoin is the only Proof-of-Stake blockchain that uses modern Bitcoin code, making it the perfect drop-in replacement.

Peercoin also has a dedicated community, is actively developed, fairly distributed, has low barriers of participation, can do everything that Bitcoin does, minus the 13 TWh of energy usage, and it's not a scam.

Populous is a network designed to offer small and medium-sized enterprises (SMEs) invoice liquidity for up to 90 days. Launched in 2017, Populous is designed to enable peer-to-peer (P2P) interaction between enterprises, boost liquidity and solve problems with working capital for SMEs.

By relying on blockchain technology and smart contracts, the Populous network facilitates decentralized communication between businesses and allows them to share liquidity pools. According to the network’s official whitepaper, there is a need for liquidity in the sector, and Populous is trying to bring the solution. By providing short-term liquidity to enterprises through P2P lending, the network gives enterprises quick access to capital, which cannot be achieved by waiting for customers to settle invoices.
