Blockchain is a distributed ledger-based technology that enables you to uniquely solve inefficiencies in business networks. However, like any exchange of value, it makes sense only when used by multiple parties. With the myriad of existing protocols and proposed applications, it can be difficult to decide on the right approach to implement a blockchain solution that best fits a given use case. In this talk, we dissect use cases and blockchain architectures built for multi-party consortiums in energy and financial services sectors. Our partners GuildOne and Kaleido highlight the architectural approaches to shared IT and consortium building using Corda and Ethereum protocols.
