Cryptonex is a blockchain-based payment system that offers its users a decentralized platform to make fiat and cryptocurrency transactions. Users can convert fiat and cryptocurrencies. The Cryptonex network is based on the scrypt algorithm. It also enables debit and credit cards transactions as well as mobile payments.
Cryptonex uses a Proof-of-Stake (PoS) consensus mechanism and offers higher transaction speeds at lower fees.

Obyte, previously known as Byteball, is a conditional payment network that is built on scalable technology, and is enabled by smart contracts. It also allows users to create their own ICO and issue their own digital assets. Conditional smart payments can be used for a variety of decentralized applications, including: insurance, betting, and prediction markets. Obyte's platform is smart contract enabled and allows users to control their identity better than some other payment systems. Obyte also allows users to make transactions through text messages or with a chat bot. Obyte's transaction data is stored and ordered using directed acyclic graph (DAG) rather than blockchain. This allows all users to secure each other's data by referencing earlier data units created by other users, and also removes scalability limits common for blockchains.
