Blockademia is a decentralized information system for both issuing and checking the authenticity of issued diplomas, certificates, and other documents using Cardano blockchain transactions. Cardano blockchain transactions records are public, immutable and unique. Each transaction has date and time of transaction written as part of transaction as well as other metadata which ensure each transaction’s uniqueness. Using these blockchain features, Blockademia ensures the permanence and immutability of the issued entry, which includes document metadata and subsequent authenticity checks. Blockademia is a modular application with predefined functionality depending on the size and issuer requirements.
