ABSTRACT: The Stellar System is the first blockchain to incorporate permissionless membership with traditional quorum-based permissioned algorithms. This is achieved by the innovative introduction of local slices, whose various combinations across the network create implicit quorums. In this talk I’ll describe the principles underlying the infrastructure of the Stellar blockchain system. In addition, I’ll show that the Stellar infrastructure provides stronger guarantees than realized before, and I’ll propose a remarkably simple byzantine fault-tolerant consensus algorithm that runs over the Stellar infrastructure. Joint Work with: Eli Gafni, UCLA, David Mazieres, Stanford. BIO: Since January 2017 Giuliano Losa has been working with with Eli Gafni at UCLA. Giuliano Losa previously worked as a post-doc at Virginia Tech in the Systems Software Research Group. Before joining Virginia Tech, Giuliano Losa worked as a software engineer at ELCA, in Switzerland, where he and his colleagues developed a new encryption system for the Swiss inter-bank clearing network. Giuliano Losa holds a PhD in Computer Science from EPFL, Switzerland.
