Bytecent is developing a decentralized rewards network powered by blockchain. Bytecent allows merchants to create customer loyalty programs that are cross-site and cross-platform compatible. Consumers are not restricted to using their rewards with just one merchant, and can redeem them anywhere Bytecent is accepted. In addition to secure transactions and portability, Bytecent never expire and there are no limitations on how many Bytecent you can accumulate or spend. BYC can be converted to Bitcoin, cash, and gift cards. Bytecent uses a variation of Proof-of-Work (PoW) for consensus that requires miners to manually attend to their computers and is called Proof-of-Miner (PoM). It's designed to prevent the use of advanced and autonomous mining hardware. Avanquest Software, a leading developer of consumer software, has implemented Bytecent for their rewards program.

Nxt is a blockchain platform developed by Jelurida, which is also developing the Ardor blockchain. Nxt's goal is to improve upon existing blockchain platforms with a modular toolset that enables users to create their own digital assets that can be listed on decentralized marketplaces. Nxt also features community driven voting mechanisms and has an architecture that separates the blockchain into parent and child blockchains.
The network is powered by the NXT token and has a Proof-of-Stake (PoS) consensus mechanism.

QuarkChain is building a blockchain with a focus on speed and scalability. They hope to significantly improve transaction times and reduce fees with an architecture that will rely on a two-layered blockchain and elastic sharding. QuarkChain uses a hybrid Proof-of-Work (PoW) consensus mechanism that is ASIC-resistant. Transactions are first confirmed on one blockchain layer, and then on the second. The network will be powered by the QKC coin.
