Welcome to the 9^th 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.

Blockchain for Trust and Transparency: Transforming Agriculture and Education

Abstract: Blockchain technology is redefining the foundations of trust and transparency across diverse sectors, including agriculture and education. In this talk, I will explore how blockchain solutions are addressing critical challenges in these fields, fostering integrity, efficiency, and accountability. Drawing from key Australian Government initiatives, this talk will delve into three transformative projects: (1) Agriculture Supply Chain: Leveraging blockchain to enhance traceability and authenticity in agricultural supply chains, ensuring product integrity from farm to table. (2) Greenhouse Gas Monitoring: Employing blockchain to track and verify agricultural greenhouse gas emissions, supporting sustainability and compliance with environmental standards.(3) Education Credentials: Implementing blockchain to authenticate academic records and prevent credential fraud, safeguarding the value of education and empowering institutions globally. By sharing insights from real-world deployments, this talk aims to inspire further innovation and collaboration, showcasing blockchain’s pivotal role in shaping trustworthy digital ecosystems for the future.

Title: From Blockchain to Parametric Insurance

Abstract: This presentation explores how blockchain technology, combined with formalised trust systems, can address real-world challenges, illustrated by an automated parametric insurance product design. The core issue lies in the reliance on noisy, incomplete, and potentially adversarial third-party data to trigger transactions, while participants expect accurate payouts, verifiable evidence trails, and accountability. While blockchain platforms offer foundational capabilities, native currency, smart contracts, append-only ledgers, and automated execution via oracles, they cannot inherently verify the validity or trustworthiness of external inputs. In parametric insurance, where such data dependency is unavoidable, coupling blockchain with a trust system is crucial. By binding oracles to “trust providers”, the solution mitigates third-party data risk and supports multiple sources of truth, stabilising event indices and payouts while retaining blockchain’s core benefits. Though demonstrated in a parametric insurance case study, this framework can be applied to other domains that benefit from trust-bound oracles, on-chain agreements, settlements, and auditable evidence

Bio: DR. Tahiry Rabehaja is the Principal Software Engineer at Risk Frontiers, an Australian company delivering quantitative natural catastrophe risk modelling for insurers, reinsurers, network service providers, emergency services, government agencies, and more. With a background in pure mathematics, he earned a joint PhD in Computer Science from Macquarie University (Australia) and The University of Sheffield (United Kingdom) in 2014. He previously worked as a researcher in information security at Macquarie University, focusing on theoretical computer science, quantitative information flow, blockchain applications, and trust systems, with results published in peer-reviewed journals and conferences. Since joining Risk Frontiers, he has led the design, implementation, and maintenance of the company’s software solutions, overseeing multiple high-profile product development initiatives. Alongside his engineering role, he remains active in research, exploring applications of blockchain to address real-world challenges, including those in the insurance industry.
