Scaling Blockchain Applications with Pub/Sub

Abstract

The world of distributed ledger technology(DLT) has been getting signicant attention. Many new applications want to utilize the trustless model and the high consistency guarantees this technology grants. This thesis aims to identify the needs of various business use cases and explores how DLT technology can be adapted to suit these applications. We recognize existing initiatives to adopt certain DLTs with some applications, however, there still exists gaps between these initiatives and production grade solutions. We provide a list of applications that can utilize the features of DLT technology and propose an encompassing structure to facilitate the needs of these applications. Specically, we focus on a DLT-based publish and subscribe system for a subset of the interested applications. We provide the design and rationale behind the technology selection and analyze the relationship between DLT technology and Pub/Sub.
