Welcome to the Distributed Systems and Ledgers Lab


The Distributed Systems and Ledgers Lab is part of the IFS Institute for Software at the HSR Hochschule für Technik Rapperswil, University of Applied Sciences in Rapperswil, Switzerland.

We focus on applied research with the newest technology, innovative design and strong engineering in all aspects of distributed systems, including blockchains. We recognize the importance of open communication between industry, institutions, start-ups, and students.

The DSL lab is striving to expand the frontier of innovation in this field by fostering productive discussion and collaboration, supplemented with ground-breaking applied scientific progress.

The DSL Lab works on several open source projects, notably, Bazo, TomP2P, and ICOnator.

  • Bazo is a permissionless blockchain to test and evaluate mechanisms such as proof-of-stake or sharding. Bazo is a research blockchain with the main goal of testing new algorithms and mechanisms.
  • TomP2P is a peer-to-peer library that implements a DHT and offers other features as well. The latest version is fully encrypted and can traverse NATs and firewalls.
  • ICOnator is an easy, secure, configurable, and scalable open source ICO engine. It is a Spring Boot application that uses message queues for scalability.
