Free access seminars for our Research and Industry community
During this proving time, we recognise the difficulties and sense of isolation that many are experiencing. While many events and conferences have been cancelled worldwide, UCL CBT believes that now more than ever it is essential to stay focused and keep pushing the boundaries of knowledge with a sense of solidarity and altruism.
In this spirit, we launched a massive series of Online Open Seminars. These will be free access seminars promoted by the UCL CBT to give voice to our Research and Industry community. Find below the schedule for 2020.

Accounting Information Systems and Blockchain. X-Accounting.
Modern organizations are heavily reliant on Information Systems (IS) for management. Among information systems, Accounting Information Systems (AIS) play the protagonist role. The more developed AISs are integrated with Enterprise Resource Planning (ERP) and other IS systems and constitute their essential fulcrum. A main objective of this paper is to justify the importance of AIS mainly from a legal and risk perspective. Another aim of the paper is to present the risks and challenges to AIS. We argue that in order to manage existing and emerging risks a new paradigm is needed.
Some attempts have been made both in the academic and industrial fields to implement blockchain in accounting. However, the blockchain applications in accounting has so far been relatively limited. We propose X-Accounting a three-book and three-axis accounts system based on the use of blockchain. X-Accounting is an innovative method that first of all assist in managing risks and attempts to overcome other challenges in terms of privacy and security, implementation, transparency, and effective audit and compliance
Keywords: AIS, Triple Entry Accounting, X-Accounting, Risk Management.
Building markets around keystone species’ ecosystem services for fighting climate change and protecting biodiversity
WALID AL SAQQAF, REBALANCE EARTH
According to the IMF, the tusks of an African Forest Elephant are valued at $40,000. However, the value of the carbon sequestration services done by these elephants, over their 60-year average lifespan, is $1.75m. We have a market for a dead elephant but we don’t have one for a living elephant.
Carbon sequestration is just one of the many ecosystem services provided by these elephants. The IMF didn’t value the other ecosystem services such as evapotranspiration that elephants provide within a rainforest. This water evaporation ensures stability, agricultural productivity and resilience for populations all around the Congo basin for example.
Join us in this seminar to discover how Rebalance Earth is using innovative technologies such as blockchain, artificial intelligence and internet of things to “augment” natures’ solutions such as forest elephants and other keystone species’ ecosystem services for fighting climate change and protecting biodiversity.
The Impact of Taproot and Schnorr on Address Clustering Analysis of Bitcoin Transactions
ALEXI ANANIA, CAMBRIDGE CENTRE FOR ALTERNATIVE FINANCE
Bitcoin Core developers have two new technological improvements planned for the Bitcoin Core client in 2020: Taproot and Schnorr. These upgrades were formally suggested in BIPs 340, 341, 342 and provide solutions to improve the privacy and anonymity of bitcoin transactions. Thus far, a technique called address clustering has been successfully used by law enforcement organizations and other forensic investigators to trace pseudonymous bitcoin transactions to a real world identity. In this paper, we examine the implications of Taproot and Schnorr on clustering analysis, to conclude that the aforementioned BIPs are anticipated to have minor impacts. Thus address clustering analysis will continue to be a useful heuristic for forensic investigators, once Taproot and Schnorr are fully implemented.

War of Attrition and the cost of smart contracts in Ethereum
NICOLA DIMITRI, UNIVERSITY OF SIENA
Ethereum has been the first peer-to-peer decentralized platform to allow for the execution of smart contracts. These are contracts which are implemented automatically, hence do not need a third party for their enforcement. Users wishing to execute smart contracts in Ethereum have to pay the miners for their computational costs. To do so they invest a sum before running the contract, and so before knowing exactly how much the computational cost will be. Such sum, called gas fee, is the product of the so called gas limitwithgas price. If the gas limitis higher than the amount of gas used by the platformfor computing the contractthen the user pays only for the contract cost and is reimbursed the exceeding investment. If instead the gas limitis below the gas needed for contract computation then the user pays the gas fee, because the platform spent resources in computation, but the contract will not be implemented. In the paper we argue that such payment scheme for smart contracts is analogous to a War of Attrition, that is to a second price all-pay type of context. Based on this we discuss how users could optimally choose how much to invest to pay for smart contracts in Ethereum.
Antitrust in the Blockchain Era
GIOVANNA MASSAROTTO, UNIVERSITY OF IOWA
Similar to the Internet Era, which generated new value chains based on digital marketplaces, the blockchain has the potential to be the next cutting-edge technology which will revolutionize markets. Blockchain technology built on a consensus mechanism can make intermediaries [or third parties] unnecessary and reduce the market power of today’s centralized platforms. Antitrust enforcers should oversee the transformation of digital markets by means of blockchain technology to prevent anticompetitive conduct that might block the path to innovation. Using the Web as a model of reference, a public blockchain could run on universal and open protocols; with goods and services traded in a single universal blockchain. Antitrust enforcers are fundamental in keeping blockchain markets open and free. Rather than leading to the death of antitrust and regulation, blockchain will require more sophisticated versions of both.
Dynamics of fintech terms in news and blogs and specialization of companies of the fintech industry
ROSARIO NUNZIO MANTEGNA, PALERMO UNIVERSITY, ITALY AND COMPLEXITY SCIENCE HUB, VIENNA, AUSTRIA
We perform a large scale analysis of a list of fintech terms in (i) news and blogs in English language and (ii) professional description of companies operating in many countries. The occurrence and co-occurrence of fintech terms and locutions shows a dynamics revealing a semantic stratification and a progressive evolution of the list of fintech terms in a technical vocabulary. By using methods of complex networks that are specifically designed to deal with heterogeous systems, our analysis of a large set of professional description of companies shows that companies dealing with fintech topics, services, and products are specialized to some degree with respect to the attributes of country, city, and economic sector. By using the approach of statistically validated networks, we detect geographical and economic specialization of a set of companies operating in the multi-industry, geographically and economically distributed fintech movement.
New Sources of Risk (and the case for building antifragile systems)
NAVROOP SAHDEV, MIT MEDIA LAB AND THE DIGITAL ECONOMIST
“The natural world embodies antifragility as a key systemic property. But when it comes to human-made artificial systems, we aren’t very good at building antifragile systems just yet. The loophole is our limited understanding of how “reality” — the sum total of processes and natural laws that bound us — works and how to construct systems that mimic it. Instead, we’ve built systems that are at odds with the antifragility of the natural world. The defining question is that when the dust settles down, would we come out stronger or would it be business as usual? What does building an antifragile system — that gains from volatility and stressors — look like and how to design them?”
REA, Triple-Entry Accounting and Blockchain: Converging Paths to Shared Ledger Systems
JUAN IGNACIO IBAÑEZ, UNIVERSIDAD CATÓLICA DE CÓRDOBA, ARGENTINA
In recent years, the concept of shared ledger systems offering a single source of truth has begun to put traditional bookkeeping into question. To date, its historical development remains unclear and under-researched. This paper conducts a genealogical analysis of shared ledger systems from their early forms such as Resource-Event-Agent (REA) accounting and triple-entry accounting (TEA) to their present incarnation in blockchain. We show how accounting frameworks developed between the 1980s and the early 2000s constitute the historical roots of TEA and have impacted much-discussed blockchain applications of today. As such, we duly acknowledge the influence of each individual contributing to this development, correct common misconceptions and map out how the paths of REA, TEA and blockchain converge in the realm of shared ledger systems.
Blockchain and Sustainability: Past, Present and Future
HORST TREIBLMAIER, MODUL UNIVERSITY VIENNA
Among many other things, blockchain has been hailed as a technology that can help mankind to solve numerous sustainability issues. Simultaneously, the proof-of-work consensus algorithm, which is frequently applied in public and permissionless blockchains, has been described as a disaster for the environment, indicating that this technology has both positive and negative repercussions when it comes to sustainability. In this presentation I am going to summarize previous academic research on how blockchain can positively and negatively impact environmental, social and economic sustainability. Furthermore, I will present several promising industry projects and a framework to categorize the sustainability impact of blockchain technology. The main goal of this talk is to create awareness for the sustainability implications of blockchain and to encourage systematic research in this field.
If I Ruled the World: The Role of Personal Values in Blockchain Adoption Decisions
CONSTANTIN LICHTI, JOHANNES GUTENBERG UNIVERSITY OF MAINZ
Given the growing pervasiveness of information technology (IT) in people’s everyday lives, understanding the impact of personal values (i.e., motivational goals that serve as guiding principles in the life of a person or group) on the individual decision-making process towards contemporary technology adoption becomes increasingly important. However, little is known how personal values may shape the perception of IT towards its intention to use. In this vein, blockchain technology (BT, i.e., a distributed ledger for conducting disintermediated transactions of digital assets) poses a novel case where values play an especially important role from the very inception of the concept by Bitcoin. To address this lacuna, we draw on the Schwartz value theory and develop and test a model of individual antecedents of BT adoption decision-making. Using a metric conjoint experiment, we study use intention judgments of public-permissionless BT made by potential users. Next to the understanding of how BT characteristics can enhance its adoption in society, our multi-level approach investigates the moderating importance of potential users’ personal values on use intention decisions, which offer novel insights into the individual adoption of IT. We derive implications for IT adoption and offer practical implications for blockchain developers as well as managers.
