The Request Network is developing a decentralized payment network. Their goal is to enable easily implemented payment requests on the blockchain. The company wants to create a network that will have many of the invoicing and auditing functionalities of Paypal, and will allow anyone, anywhere to request a payment. Request wants to leverage the ability of blockchain to eliminate third parties in online payments. Their network is meant to be compatible with other systems and to allow a large degree of integration and compliance across platforms and countries.

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.
