Opporty is a blockchain-powered, three-layered business relationships ecosystem, consisting of a Proof-of-Expertise protocol, a conditional business scoring system, and a B2B/B2C marketplace. Opporty ensures transparency and security, standardizes procedures, and creates an environment of cooperation that instills trust between parties doing business. Aspiring to become a global business marketplace and an expertise validation provider on the Blockchain, Opporty offers a solution that establishes and grows trusted business relationships globally. Opporty heavily relies on its Proof-of-Expertise protocol that, while collecting and analyzing transaction metadata, empowers Opporty’s scoring system to attach domain-relevant expertise to digital business identities and individually rank every vendor and service provider. This ecosystem allows for more secure domestic and international transactions, corporation and government procurement, and supply chain risk management. 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). Plasma Cash protocol allows for the creation of child blockchains, which are governed by a parent blockchain. These child chains can have different consensus rules, functionality and underlying base tokens. Such extensions naturally fit with Proof-of-Expertise, with OPP as the underlying token used for manipulation, and allows for the development of private, blockchain-powered applications, such as Opporty Enterprise Solution. Given the technologies utilized, Opporty Enterprise Solution can be implemented onto third-party platforms and applications. It can be used in enclosed corporate environments that need all data to be kept private and inaccessible to third parties, outside of the system. Corporations can implement OES to enjoy safe and secure storage of transaction metadata, blockchain-based processing of transactions, privacy of selected transactions, and transaction analysis to assign scores for specific activities. Specific use cases of Opporty Enterprise Solution include: production tracking, food safety and certification, cross-border payments and clearance, supply chain visibility, automatic dispute settlement, and asset transfer.
