Opporty is a blockchain-powered, three-layered business relationships ecosystem, consisting of Proof of Expertise Protocol, a Business Scoring System, and a Marketplace Platform. Opporty ensures transparency and security, standardizes procedures, and creates an environment of cooperation that instills trust between parties doing business. Oppory aspires to become a global business marketplace and an expertise validation provider on the blockchain. With Ethereum’s Plasma Cash Protocol as its underlying technology, Opporty has developed a permission-based version of the Opporty ecosystem called Opporty Enterprise Solution (OES). It can be implemented onto third-party platforms and applications, and can be used in enclosed corporate environments to enable more secure storage of transaction metadata, blockchain-based processing of transactions, privacy of selected transactions, and transaction analysis to assign scores for specific activities.
