Dero is developing a Proof-of-Work (PoW) blockchain with a DAG block structure. Their goal is to enable anonymous and fast transactions, with a high degree of encryption. The platform will also have smart contract functionalities.

Bytecoin is a privacy focused blockchain that aims to be completely anonymous. It is the first digital currency based on CryptoNote technology and uses ring signatures. Bytecoin utilizes one-time addresses and multi-signatures to enhance security. Bytecoin has high transaction speeds and users are in complete control their personal information. Any identifiable details can only be seen if you allow it. Bytecoin, and CryptoNote, have led to several popular forks. Monero and Dash are both Bytecoin forks. The CryptoNote Proof-of-Work (PoW) algorithm was designed to provide ASIC resistance and enables anyone with a personal computer to mine it.

Stealth is a cryptocurrency focused on privacy and and speed. The Stealth blockchain has a Quantum Proof-of-Stake (qPoS) consensus mechanism that is designed to enable almost instant transactions with improved privacy. Validators on the network are assigned a short quantum of time to validate transactions. The protocol combines two types of blockchain ledgers, for different types of transactions, to improve validation speeds on their platform. The network is powered by the XST coin.
