Ontology is an open-source, high-performance blockchain focused on decentralized identity and data. Ontology's unique infrastructure enables cross-chain interaction and Layer-2 scalability, giving organizations the freedom to create an enterprise blockchain that meets their specific requirements. To improve speed, security, and trust, a set of decentralized identification and data exchange protocols has been developed.Without prior understanding of distributed networks or blockchain technology, businesses can use Ontology. There were nearly no options for enterprises to incorporate blockchain into their infrastructure without substantial knowledge of blockchain before the debut of Ontology in 2017.The platform's main user benefits are divided into two categories: 1) ONT ID is a decentralized, tamper-resistant identification architecture. 2) Distributed Data Exchange Framework (DDXF): a framework for distributed data management and exchange.
