With more blockchain networks being developed for specific applications and across layers of the stack, interoperability has emerged as one of the crucial features of blockchain technology to expand the blockchain tenets across multiple independent blockchain networks. Still a maturing technology, blockchain interoperability is undergoing research and development of solutions with different properties and tradeoffs. The technology necessary for achieving it is fragmented and a formal approach to the problem of general-purpose blockchain interoperability is still lacking. In this talk, Dhinakaran and Rafael will analyze the problem of blockchain interoperability from theoretical and practical standpoints. They will start by defining it and present an ontology for interoperability solutions. They will then present their existing standardization efforts in the IETF DLT Gateway Interoperability group. After that, they will present their ongoing work at the Hyperledger Interoperability Task Force on providing a formal security definition of interoperability across distributed ledgers using the framework of universal composability that is vetted by the cryptography research community.
