Cronos Whitepaper: This document, dated December 2018, introduces Cronos (CRSX), a Proof-of-Stake masternode cryptocurrency aimed at improving the masternode ecosystem. It identifies problems within the existing market, such as insecure presales, and presents Cronos's "Presale-Suite" as a solution using smart contracts. The paper outlines technical specifications, the reward structure, and a roadmap including a coin launch, software releases, and community building efforts. Furthermore, it includes disclaimers and risk statements, emphasizing that CRSX is a utility coin and not a security.
