BlockCerts is a fork of Ethereum blockchain with its own economy and token standard. The economy includes the main currency - BLOCKCERTS (BCERTS) as the core currency. Being developed in cooperation with Oracle, the blockchain and server modules of the system are to be fully compatible with Oracle server infrastructure. BCERTS are then converted by smart contract-based applications into different tokens, each of them individual for its application. These secondary tokens play the role of digital certificates, i.e. medical prescriptions and property ownership proof. The goal of this system is to provide a transparent and immutable record of operations within these applications. Additional KYC process will allow users with different roles within said applications to perform the required actions and validate each others' identities.
