Real-T？me Verifiable Educational Certificates With Block Chain

The block chain is a structure that allows digitized information to be recorded on different nodes on a network, allowing the recorded information to be shared with other nodes to be verifiable and transparent. Each node in the distributed structure on the network monitors the operations on the network through the programs. Intelligent contracts control the accuracy of transactions, updating the distributed book of each node and registering it as an identical copy in all nodes. With the encryption and tree structure in the system, nodes can track how new edits or entries are initiated, acknowledged, saved and distributed, but they can not intervene on their own. Since the system is highly reliable at a distance from centrality, it has attracted interest in the trust-based sectors. Working with the block chain has also been started to ensure the reliability of educational certificates, which are often subject to fraud, and to perform real-time validation processes. The purpose of this study is to create a block-chain based application framework by briefly introducing the characteristics, development and operation methods of the block chain, expressing the importance of instant verification of the educational certificates and how block chain can be used for this verification
