The 7th Symposium on Distributed Ledger Technology

(Affiliated with ICFEM 2023)

30 November - 1 December 2023 - Brisbane, Australia

Welcome to the 7th Symposium on Distributed Ledger Technology (SDLT)

Distributed Ledger Technology is an emerging technology, which provides the way to store and manage information in a distributed fashion. It enables the creation of decentralized crypto-currencies, smart contracts, eGovernance, supply chain management, eVoting etc over a network of computer systems without any human intervention. Unprecedented reliability and security over other cryptographic schemes has expanded the application domains of blockchain including financial services, real estate, stock exchange, identity management, supply chain, and Internet of Things.

The goal of this symposium is to provide a forum for researchers, business leaders and policy makers in this area to carefully analyse current systems or propose new solutions creating a scientific background for a solid development of innovative Distributed Ledger Technology (DLT) applications.

Keynote Speakers

Associate Professor Vincent Gramoli, University of Sydney and Redbelly Network

Redbelly - Australian Sovereignty in Blockchain

Abstract: In this talk, Vincent Gramoli will present the Australian-made research, design and development of the Redbelly Blockchain. He will present a series of innovations like the first formally verified blockchain consensus algorithm, the patented superblock optimisation that changes the traditional block creation competition into a collaboration to achieve scalability, the introduction of accountability to disincentive hackers from stealing assets.

Bio: Vincent Gramoli is the Founder and CTO or Redbelly Network. He received a Future Fellowship from the Australian Research Council and leads the Concurrent Systems Research Group at the University of Sydney. With his group he reported vulnerabilities in Ethereum and developed the Redbelly Blockchain that encapsulates DBFT, the first model-checked blockchain consensus protocol. In the past, Gramoli has been affiliated with INRIA, Cornell, CSIRO and EPFL, and he recently received the best paper awards of ICDCS'21, IPDPDS'22 and ICDCS'22. He teaches Blockchain Scalability on Coursera to 5000 students and his textbook is published by Springer.

Professor Shiping Chen, CSIRO Data61

Blockchain Interoperability - Concepts, Technologies & Standardization

Abstract: With the increasing number of blockchains, there is a strong demand for sharing data and transferring digital assets across these blockchain systems, called Blockchain Interoperability. In this talk, Prof. Chen will introduce the basic concepts of blockchain and blockchain interoperability. He will also present and discuss the key existing solutions and technologies for blockchain interoperability. In particular, he will share his ongoing collaborative work on IETF RFC on Secure Asset Transfer Protocols (SATP).

He also holds a conjoint/adjunct professor with UNSW, UTS and Macquarie. He has been working on distributed systems for 20+ years with a focus on performance & security. He has published 300+ papers in these research areas and won 5+ Best Paper awards on top venues on software engineering and distributed systems (e.g., ICSE-2018 and CCGrid-2015). He is active in blockchain, cloud and service computing research communities through journal editorships and conference services, such as PC Chair of ICBC-2018 and ICBC-2022, executive committee member (ECM) of IEEE TCBIS and ECM of IEEE TCSVC. He is also a member of IETF RFC WG on Secure Asset Transfer Protocols (SATP). He is a senior IEEE member and a fellow of the Institution of Engineering Technology (IET). He can be reached via

Dr Paul Ashley, Anonyome Labs

Slope of Enlightenment for DLT-based DID-Methods

Abstract: The decentralized identity community has gradually drifted away from initially adopted DLT-based DID-Methods and towards the adoption of more centralised approaches. With implementation experience, however, the limitations with these centralized approaches have become increasingly evident. Therefore, it is time to reassess the legitimacy of centralized approaches and make the leap back to decentralized DLT-based DID Methods.

Bio: Dr Paul Ashley is CTO at Anonyome Labs. The company brings technology to everyday users that allow them to interact online and offline in safety, privacy and control. Paul?s responsibilities at Anonyome Labs includes product management, development, emerging technologies and IP protection (patents). Paul has worked extensively in software product development for more than 30 years, providing technical leadership across a range of security, privacy and identity products.

Mr Darren Rogan, Tech Entrepreneur and Speaker.

Decoding Crypto Networks: Gas Dynamics, Economic Significance, and Ethereum's Evolution into a Settlement Layer.

Abstract: This talk delves into the economic intricacies of Gas in crypto networks and Ethereum's pivotal shift to a Layer 2 solution. Gas, a fundamental unit on blockchain networks, dictates transaction fees and resource allocation but introduces challenges through price volatility. The talk examines the economic consequences of Gas fluctuations, exploring their influence on user behaviour, network scalability, and overall sustainability. Ethereum's strategic move with Layer 2 is spotlighted as a solution to scalability issues, offering insights into the delicate balance between economic efficiency and user experience. Attendees will gain a nuanced understanding of the evolving role of economic considerations in shaping the future of blockchain technology, particularly in the context of Ethereum's transformation.

Bio: Darren Rogan has over 15 years of experience building and launching digital products and startups. Rogues Lab is an innovation and advisory firm at the forefront of emergent technologies, dedicated to supporting startups, scaleups, DAOs, and corporates.

Darren has been involved in startups and projects in the UK, US, and Australia. Darren has also been the EiR for the UQ startup accelerator iLab for several cohorts and continues to be involved in multiple startup accelerator programs, has worked with over 150 companies helping them to understand how to deliver what is actually valuable faster.

Dr Sushmita Ruj, The University of New South Wales

Layer-2 Scaling Solutions for Blockchains

Abstract: Scalability is a major challenge in blockchains. One way is to design faster consensus algorithms (Layer-1 solutions). Another way is to introduce techniques to process transactions off-chain. The later solution is known as the Layer-2 solution. We will give a brief overview of Layer-2 solutions including payment channels and state channels and ZK-Rollups. Then we will discuss about different types of rollups, design challenges and constructions.

Bio: Sushmita Ruj is Faculty of Engineering Lead of UNSW Institute for Cybersecurity, IFCYBER and Senior Lecturer in the School of Computer Science and Engineering at UNSW, Sydney. Her research interests are in applied cryptography, post quantum cryptography, blockchains and privacy enhancing technologies. She designs practical, efficient, and provably secure protocols that can be deployed in real-world applications. She has won several competitive grants like Samsung GRO Award, NetApp Faculty Fellowship, Cisco Academic Grant. She is an Associate Editor of the Transactions on Information Forensics and Security. She served as a working group member of The National Blockchain Roadmap of Australia and a working group member of the First Blockchain initiative by Reserve bank of India. Sushmita is a senior member of both ACM and IEEE.
