Abstract Blockchains are used for distributed consensus where all nodes agree on the validity of transactions in a block without needing a central trusted party. This has found numerous applications in Fintech, Supply chains, and contracts. The consensus is binary - agree or disagree - True or False. In this talk, Prof. Jain will present recent extensions by his team that allow blockchains to be used for group decisions that may not be binary. In this era of big data, we need to move blockchains beyond data storage to provide knowledge. Blockchains can be used for group decision making and risk management when the group sizes are large, and group members may want to remain anonymous. Prof. Jain will describe numerous use cases of this idea. Such situations frequently arise in network security, such as, in deciding about spams, viruses, intrusions and attacks, BGP domain route injection, etc.
