Abstract (sommario):

Artificial general intelligence (AGI) progression metrics indicate AGI will occur within decades. No proof exists that AGI will benefit humans and not harm or eliminate humans. A set of logically distinct conceptual components is proposed that are necessary and sufficient to (1) ensure various AGI scenarios will not harm humanity, and (2) robustly align AGI and human values and goals. By systematically addressing pathways to malevolent AI we can induce the methods/axioms required to redress them. Distributed ledger technology (DLT, “blockchain”) is integral to this proposal, e.g., “smart contracts” are necessary to address the evolution of AI that will be too fast for human monitoring and intervention. The proposed axioms: (1) Access to technology by market license. (2) Transparent ethics embodied in DLT. (3) Morality encrypted via DLT. (4) Behavior control structure with values at roots. (5) Individual bar-code identification of critical components. (6) Configuration Item (from business continuity/disaster recovery planning). (7) Identity verification secured via DLT. (8) “Smart” automated contracts based on DLT. (9) Decentralized applications—AI software modules encrypted via DLT. (10) Audit trail of component usage stored via DLT. (11) Social ostracism (denial of resources) augmented by DLT petitions. (12) Game theory and mechanism design.

Abstract (sommario):

The article focuses on whether it is possible to use new technologies such as distributed ledger technology (DLT) in shareholder ledger maintenance systems. The article uses Estonia as an example to describe the shortcomings of shareholder ledger maintenance regulation and possible suggestions for reform and applies the principle of technology-neutrality to the subject matter to assess whether the regulation allows the adoption of new technologies, such as DLT, in ledger maintenance. The aim of the principle of technology-neutrality is to secure that the regulator does not create regulation that prefers any particular technology and discriminates against other technologies. Any regulation that is built around a pre-existing technology could suffer from preferring the use of that particular technology and consequently hinder innovation. In the article it is examined whether the ledger maintenance models used in Estonia are benefitting or suffering from the non-existence of technology-neutral technical standards for ledger maintenance and whether the differentiation of treatment of shareholder ledger administrators is justified on the basis of the principle of technology-neutrality.

Abstract (sommario):

Distributed Ledger Technology (DLT) is making the first steps toward becoming a solution for the growing number of various decentralized systems worldwide. Unlike pure Blockchain, DLT finds many uses across different industries, including eHealth, finance, supply chain monitoring, and the Internet of Things (IoT). One of the vital DLT features is the ability to provide an immutable and commonly verifiable ledger for larger-scale and highly complex systems. Today?s centralized systems can no longer guarantee the required level of availability and reliability due to the growing number of the involved nodes, complicated heterogeneous architectures, and task load, while the publicly available distributed systems are still in their infancy. This paper aims to provide an exhaustive topical review of the state-of-theart of Distributed Ledger Technology applicability in various sectors. It outlines the importance of the practical integration of technology-related challenges, as well as potential solutions.

Abstract (sommario):

This paper reviews what stage the central banks of the world’s leading economies are at in their study and adoption of distributed ledger technology (DLT) to reengineer their various systems and functions. A brief description of DLT will be given, followed by an analysis of central banks’ publications and pronouncements to determine what each central bank is doing on their journey to DLT adoption. It was found that of the central banks for which information was available, all of them have expressed interest in DLT and have evaluated it to some extent. Nevertheless, no central bank has an operational DLT-based system at this point. This is because some issues remain regarding the speed, cost of processing, security, transparency and privacy, legal settlement finality, scalability and network effects of the technology. As DLT matures, the expectation is that these issues will begin to be resolved.

Abstract (sommario):

The Distributed Ledger Technology (DLT) provides an infrastructure for developing decentralized applications with no central authority for registering, sharing, and synchronizing transactions on digital assets. In the last years, it has drawn high interest from the academic community, technology developers, and startups mostly by the advent of its most popular type, blockchain technology. In this paper, we provide a comprehensive overview of DLT analyzing the challenges, provided solutions or alternatives, and their usage for developing decentralized applications. We define a three-tier based architecture for DLT applications to systematically classify the technology solutions described in over 100 papers and startup initiatives. Protocol and Network Tier contains solutions for digital assets registration, transactions, data structure, and privacy and business rules implementation and the creation of peer-to-peer networks, ledger replication, and consensus-based state validation. Scalability and Interoperability Tier solutions address the scalability and interoperability issues with a focus on blockchain technology, where they manifest most often, slowing down its large-scale adoption. The paper closes with a discussion on challenges and opportunities for developing decentralized applications by providing a multi-step guideline for decentralizing the design and implementation of traditional systems.

Abstract (sommario):

Purpose The purpose of this paper is to assist records managers and information governance professionals to understand the challenges presented by their organization’s use of blockchain distributed ledger technology (DLT). Design/methodology/approach An extensive literature review was conducted, which revealed a multitude of articles based on research into blockchain DLT, most written from the technology perspective. This paper differs in that it applies a records management lens to an analysis of the records created, registered or stored on a blockchain. A six-stage blockchain records consideration model is provided to illustrate examples of the records management challenges presented by the implementation of blockchain DLT. Questions are posed and recommendations are made to aid the reader in developing a blockchain DLT records management and information governance strategy. Findings Because there is no one universal configuration for a blockchain DLT solution, each implementation must be analyzed to understand the resultant records management and information governance challenges. A series of questions that should be asked and answered can not only help records management and information governance professionals adapt their policies and practices to the technology but also provide a basis for discussion with those designing the blockchain DLT solutions so they can include records management features in their designs. Originality/value This paper contributes an original analysis of the implications of the adoption of Blockchain DLT for records management and information governance programs through the lens of a six-stage Blockchain Records Consideration Model.

Abstract (sommario):

In this paper, we propose a scheme that implements a Distributed Ledger Technology (DLT) based on Directed Acyclic Graph (DAG) to generate, validate, and confirm the electricity transaction in Smart Grid. The convergence of the Smart Grid and distributed ledger concept has recently been introduced. Since Smart Grids require a distributed network architecture for power distribution and trading, the Distributed Ledger-based Smart Grid design is a spotlighted research domain. However, only the Blockchain-based methods, which are a type of the distributed ledger scheme, are currently either being considered or adopted in the Smart Grid. Due to computation-intensive consensus schemes such as Proof-of-Work and discrete block generation, Blockchain-based distributed ledger systems suffer from efficiency and latency issues. We propose a DAG-based distributed ledger for Smart Grids, called PowerGraph, to resolve this problem. Since a DAG-based distributed ledger does not need to generate blocks for confirmation, each transaction of the PowerGraph undergoes the validation and confirmation process individually. In addition, transactions in PowerGraph are used to keep track of the energy trade and include various types of transactions so that they can fully encompass the events in the Smart Grid network. Finally, to ensure that PowerGraph maintains a high performance, we modeled the PowerGraph performance and proposed a novel consensus algorithm that would result in the rapid confirmation of transactions. We use numerical evaluations to show that PowerGraph can accelerate the transaction processing speed by over 5 times compared to existing DAG-based DLT system.

Abstract (sommario):

Distributed ledger technology (DLT) that stores data (usually immutable and sequenced transaction records) in a decentralized way through cryptography and consensus algorithms. The first widely recognized implementation of the blockchain took place in 2009 on the Bitcoin public blockchain. Since then, other types of blockchain have been developed for a wide range of applications and features built on common principles such as decentralization, encryption, consensus, and immutability. In particular, blockchain technology is most widely used in transaction settlement and digital currency banks and the financial sector, as well as in supply chain applications that help participants solve problems quickly and efficiently. Other use cases continue to be developed. As a form of information management, blockchain and related DLTs offer advantages over traditional databases and may help develop certain new technologies such as the Internet of Things. Blockchain regulation is currently restricted at the international and federal levels, but state-level legislation provides support and awareness of aspects of blockchain technology. Most of the current regulations are in the form of self-regulation by blockchain developers and related communities, but many challenges and risks such as data privacy and security need to be addressed in the near future.

Abstract (sommario):

Distributed ledger technology (DLT) stands to benefit industries such as financial services with transparency and censorship resistance. DLT systems need to be scalable to handle mass user adoption. Mass user adoption is required to demonstrate the true value of DLT. This dissertation first analyses scalability in ethereum and EOS. Currently, ethereum 1.0 uses proof of work (PoW) and handles only 14 transactions per second (tps) compared to Visa's peak 47 000 tps. Ethereum 2.0, known as Serenity, introduces sharding, proof of stake (Casper), plasma and state channels in and effort to scale the system. EOS uses a delegated proof of stake (DPoS) protocol, where 21 super-nodes, termed ‘block producers' (BPs), facilitate consensus, bringing about significant scalability improvements (4000 tps). The trade-off is decentralisation. EOS is not sufficiently decentralised because the BPs yield significant power, but are not diverse. This dissertation conducts an empirical analysis using unsupervised machine learning to show that there is a high probability collusion is occurring between certain BPs. It then suggests possible protocol alterations such as inverse vote weighting that could curb adverse voting behaviour in DPoS. It further analyses whether universities are suitable BP's before mapping out required steps for universities to become block producers (leading to improved decentralisation in EOS)

Abstract (sommario):

This article analyses the impact of the IOTA distributed ledger technology (DLT) on smart cities. The world population is rapidly increasing while at the same time trends such as urbanization shape future demographics. Thus, fast-growing cities face the challenge of increasing demands in resources such as energy, water, transportation, while at the same time aiming to increase life quality by reducing burdens such as pollution and waste. The concept of a “Smart City” emerged with the ambition to solve a city’s issues by creating social and economic advantages while providing efficient resource allocation processes. Nevertheless, current information communication technologies tend to underperform a smartcities systems requirement since the quantity of connected devices increases which slows down the transition of a city becoming smart. The distributed ledger technology IOTA promises to enable automated, feeless transactions and processes with a high level of integrity, which may impact the development of smart cities. In this research the IOTA technology is introduced and investigated. The advantages of IOTA compared to conventional information communication technologies and the blockchain technology are highlighted. Thereafter, the current state of IOTA in smart cities is reviewed by analysing current research and use cases. To investigate the concept of a smart city the smart city initiative framework, including its subcategories is introduced. Additionally, different experts working on IOTA integrations related to smart city initiatives were interviewed giving insights into their field ofexpertise. Finally, an analysis and discussion of the IOTA technology use cases are put into relation with the multi-level perspective framework (Geels, 2006) highlighting the positive impact of IOTA on the development of smart cities.
I den här artikeln analyseras effekterna av IOTA:s teknik för distribuerade huvudböcker (DLT) på smarta städer. Världens befolkning ökar snabbt samtidigt som trender som urbanisering formar framtidens demografi. Snabbt växande städer står därför inför utmaningen att öka kraven på resurser som energi, vatten och transporter, samtidigt som de strävar efter att öka livskvaliteten genom att minska belastningar som föroreningar och avfall. Begreppet smart stad uppstod med ambitionen att lösa stadensproblem genom att skapa sociala och ekonomiska fördelar och samtidigt tillhandahålla effektiva processer för resursfördelning. Den nuvarande informations- och kommunikationstekniken tenderar dock att inte uppfylla kraven på system för smarta städer, eftersom mängden anslutna enheter ökar, vilket gör att övergången till en smart stad blir långsammare. Den distribuerade huvudbokstekniken IOTA lovar att möjliggöra automatiserade, felfria transaktioner och processer med en hög grad av integritet, vilket kan påverka utvecklingen av smarta städer. I den här forskningen introduceras och undersöks IOTA-tekniken. Fördelarna med IOTA jämfört med konventionell informationskommunikationsteknik och blockkedjetekniken lyfts fram. Därefter granskas det nuvarande läget för IOTA i smarta städer genom att analysera aktuell forskning och användningsfall. För att undersöka begreppet smart stad introduceras ramverket för initiativet för smarta städer, inklusive dess underkategorier. Dessutom intervjuades olika experter som arbetar med IOTA-integrationer isamband med initiativ för smarta städer för att ge en inblick i deras expertisområde. Slutligen analyseras och diskuteras IOTA-teknikens användningsområden i förhållande till ramverket för flernivåperspektivet (Geels, 2006), där IOTA:s positiva inverkan på utvecklingen av smarta städer lyfts fram.

Abstract (sommario):

Distributed ledger technology (DLT) is one of the latest in a long list of digital technologies, which appear to be heading towards a new industrial revolution. DLT has become very popular with the publication of the Bitcoin Blockchain in 2008. However, when we consider its suitability for dynamic networking environments, such as the Internet of Things, issues like transaction fees, scalability, and offline accessibility have not been resolved. The IOTA Foundation has designed the IOTA protocol, which is the data and value transfer layer for the Machine Economy. IOTA protocol uses an alternative blockless Blockchain which claims to solve the previous problems: the Tangle. This thesis first inquires into the theoretical concepts of both technologies Tangleand Blockchain, to understand them and identify the reasons to be compatible or not with the Internet of Things networking environments. After the analysis, the thesis focuses on the proposed implementation as a solution to address the connectivity issue suffered by the IOTA network. The answer to the problem is the development of a Neighbor Discovery algorithm, which has been designed to fulfill the requirements demanded by the IOTA application. Dealing with IOTA network setup can be very interesting for the community that is looking for new improvements at each release. Testing the solution in a peer-to-peer specific protocol (PeerSim), with different networking scenarios, allowed us to get valuable and more realistic information. Thus, after analyzing the results, we were able to determine the appropriate IOTA network configuration to build a more reliable and long-lasting network.

Abstract (sommario):

Centralized data storage and reconciliation by trusted intermediaries has historically put financial systems in the hands of a single central parties. The emergence of bitcoin and blockchain, combined with the 2008 financial crisis, has shifted the Swedish financial sector’s traditional perspectives on democratization, centralization, transparency and automation. Trade and export finance is one of many sectors investigating how blockchain and distributed ledger technology can be used other than as a digital currency system. Swedish trade and export finance connects importers, exporters, banks, credit providers, customs, and transporters into a fragmented and complex process with many stakeholders. Sweden further has a history of quickly adopting technological innovations. Banks therefore face a dynamic environment and an inconsistent, manual operative process that removes profitability incentives in providing small enterprises with credit. The adoption of DLT could provide efficiency gains and cost savings in administration, communication, reconciliation and accounting. In this thesis, the costs, benefits, and remaining barriers of implementing distributed ledger technology in Swedish trade finance are identified. Further, Swedish contextual factors’ effect on the rate of adoption is addressed. The chosen methodology of deep interviews and thorough studying of literature provides an assessment of the potential transition dynamics, forming a foundation for future investment decisions. The conclusions drawn suggest that the main costs related to adoption lie in research and development and implementation. R&D costs for distributed ledgers in the Swedish financial sector during 2019 were approximated to USD 40 million. The main benefits of automation, efficiency and reduced level of complexity were concluded to likely outweigh the costs within approximately ten to twenty years. Experience will allow companies to optimize governance structures and consensus mechanisms, while learning to expose parts of networks into public space. The innovative, adaptive Swedish market environment presumably enables faster than average diffusion of innovation, while remaining barriers in cooperation, trust, interoperability and regulation may extend the adoption process

Abstract (sommario):

Inspired by the digital revolution to the financial industry, the discussion around central bank digital currency also attract attention from academics and central banks. The People’s Bank of China (PBOC) is also researching on China’s CBDC: digital currency electronic payment (DCEP) and announced that DCEP would be issued as soon as possible. However, the PBOC does not systematically disclose the information of DCEP. The characteristics and mechanism design are still obscured and need to be explored deeply. This thesis analysed the classification and mechanism design choices of DCEP from the perspective of two different demands: general demand and central bank demand. Based on pragmatism philosophy, we use a mixed-methods approach that is a combination of qualitative and quantitative research. Through the interview and surveys, we identified the demands from the PBOC and the general public in China and the characteristics of DCEP from official claims. Then generate the design choices via the money flower and the pyramid of CBDC models and compare the result with the demand. The analysis shows that the DCEP belongs to type B general-purpose CB digital tokens, and it would adopt a complex multi-layer hybrid architecture design, with the support from both DLT and conventional way. In conclusion, the current mechanism design choices can meet the demands from each side to a certain extent and reached a delicate balance under the trade-off between privacy and security issues. This thesis provides an insightful view on the classification and design choices of DCEP, fulfils the lack of systematic research relating to the demand and design choices of DCEP, and reveals the public’s insufficient knowledge in DCEP.

Thesis, Uppsala universitet, Teologiska institutionen, 2019. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-392161.

Testo completo

Abstract (sommario):

The issue of food traceability is one that affects a great number of sectors and policy areas. Within the EU, there is increasing demand from consumers, businesses and institutions to have more direct access to information about how food is produced, transformed, and distributed. Currently, however, practices in the industry are very much open to human error. Databases are highly vulnerable to inaccuracies and hacking, as well as deliberate faults caused by corruption or fraudulent conduct. With food traceability being so closely related to trade and public health issues, there is arguably increasing incentive for the EU to seek alternative tools to increase transparency and accountability throughout supply chains. Consequently, this paper will examine a possible alternative to current practices by evaluating the applicability of 'blockchain' technology, namely a system of digitised, decentralised ledgers, which could allow key stakeholders to access information about the provenance of food immediately, comprehensively and securely. The analysis will focus specifically on Extra Virgin Olive Oil (EVOO), one of the most adulterated products in the food industry, identifying gaps and opportunities in current traceability systems. The research question tackled in this paper, therefore, may be formulated as follows: how and to what extent could blockchain technology constitute a sustainable solution for improving the traceability of EVOO within the EU? The paper begins with a brief overview of the issue and an explanation of the research methodology used, followed by an elaboration of key terms and concepts and a detailed explanation of the principles underlying blockchain technology. Subsequently, the key challenges and opportunities associated with blockchain-based traceability systems are examined through a case study, followed by an analysis aimed at assessing the sustainability of blockchain solutions for the EVOO sector. The conclusion, lastly, provides an overview of relevant findings and proposes a final assessment.

Abstract (sommario):

Creating standardized infrastructures for new technologies has become a frequent event in recent years, forcing competing firms to together collaborate in order to develop and mutually agree on a common standard. This is due to technologies such as blockchain (distributed ledger) technology that need interoperability to reach its full potential, making the collaboration aspect crucial for organizations that want to adapt to the technology. Therefore, this study’s purpose is to identify and analyze the challenges of creating such a standardized infrastructure. A case study was used to analyze these challenges, which involved experts of blockchain technology and three Nordic banks connected to the blockchain consortium R3. First, a pre-study took place with the help of blockchain experts, who helped identify potential problems regarding blockchain (distributed ledger) technology. Secondly, a main study was conducted consisting of four interviews with key persons representing the banks, in addition to collecting secondary data via news articles, and press releases. With the help of co-opetition theory and a technical description of blockchain (distributed ledger) technology, an analytical model was developed to support the analysis of the data collection. The analysis focus on aspects of co-opetition drivers, co-opetition capabilities, co-opetition dynamics and blockchain aspects, which were used to showcase the challenges of collaborating on creating a standardized infrastructure. The result of this study highlights the importance of learning and educational aspects, the size of a cooperation and threats from other competing solutions, which generates challenges. In addition to the identified challenges, this study has also contributed to an understanding of how these aspects can come to affect a collaboration.

Abstract (sommario):

Handeln med finansiella instrument har effektiviserats avsevärt under de senaste decennierna tack vare den tekniska utvecklingen och internationaliseringen. Pappersbaserade värdepapper har ersatts av digitala finansiella instrument och investerare kan numera på ett enkelt sätt skapa värdepappersportföljer innehållande komplexa värdepapper från hela världen. En välfungerande och effektiv handel med finansiella instrument förutsätter att förtroendet existerar mellan aktörer på finansiella marknader. Idag säkerställs förtroendet inom finansiella marknader av ett antal olika finansiella intermediärer, vilka ansvarar för olika funktioner såsom clearing, avveckling och kontoföring. Transaktionskedjan avseende finansiella instrument består därmed av flera nivåer och varje enskild transaktion måste genomgå samtliga nivåer. Den finansiella handeln har ökat betydligt i omfattningen och ett betydande antal transaktioner är numera gränsöverskridande. Detta har resulterat i ett tämligen komplext, sammanlänkat och sårbart system, vilket bland annat har synliggjorts under den senaste finanskrisen år 2008. Blockkedjeteknologi, vilken är en typ av Distributed Ledger Technology, kan något förenklat ses som en databas eller ett transaktionsregister. Till skillnad från traditionella transaktionsregister, vilka i regel är centraliserade och förvaltas av olika intermediärer, bygger den nya teknologin på ett decentraliserat nätverk av aktörer utan att någon tredje part är ansvarig för verifiering av transaktioner. Blockkedjeteknologin introducerar därmed ett nytt sätt att genomföra transaktioner med digitala tillgångar, genom att förtroendet säkerställs med hjälp av kryptografiska lösningar och ett decentraliserat nätverk. Blockkedjeteknologin anses av många ha en betydande potential att effektivisera transaktionskedjan avseende finansiella instrument genom att exempelvis automatisera förandet av transaktionsregister samt integrera de olika nivåerna inom transaktionskedjan. Tekniken är dock fortfarande i en utvecklingsfas och många olika utmaningar återstår innan tekniken kan komma till användning. I Sverige präglas transaktionskedjan avseende finansiella instrument dessutom av strikta regleringar, varför frågan uppstår om huruvida lösningar baserade på blockkedjetekniken är förenliga med dagens rättsliga ramar. I denna uppsats diskuteras huruvida och på vilket sätt blockkedjeteknologin skulle kunna effektivisera vissa funktioner inom transaktionskedjan avseende finansiella instrument samt vilka rättsliga frågeställningar som uppstår i samband med tillämpning av den nya tekniken utifrån dagens rättsläge i Sverige.

Abstract (sommario):

Newly emerging cryptocurrencies and blockchain technology present a challenging research problem in the field of digital politics and economics. Bitcoin—the first widely implemented cryptocurrency and blockchain architecture—seemingly separates itself from the existing territorial boundedness of nation-state money via a process of algorithmic decentralisation. Proponents declare that the utilisation of cryptography to advance financial transactions will disrupt the modern centralised structures by which capitalist economies are currently organised: corporations, governments, commercial banks, and central banks. Allegedly, software can create a more stable and democratic global economy; a world free from hierarchy and control. In Money Code Space, Jack Parkin debunks these utopian claims by approaching distributed ledger technologies as a spatial and social problem where power forms unevenly across their networks. First-hand accounts of online communities, open-source software governance, infrastructural hardware operations, and Silicon Valley start-up culture are used to ground understandings of cryptocurrencies in the “real world.” Consequently, Parkin demonstrates how Bitcoin and other blockchains are produced across a multitude of tessellated spaces from which certain stakeholders exercise considerable amounts of power over their networks. While money, code, and space are certainly transformed by distributed ledgers, algorithmic decentralisation is rendered inherently paradoxical because it is predicated upon centralised actors, practices, and forces.

Abstract (sommario):

A tecnologia de registro distribuído (DLT – Distributed Ledger Technology) pode ser muito útil para o tratamento de dados pessoais em conformidade com a Lei Geral de Proteção de Dados Pessoais (LGPD), devido a características como transparência e segurança. No entanto, outras características como a imutabilidade e o caráter distribuído podem dificultar essa tarefa. Assim, este trabalho analisa os desafios da conciliação entre DLT e o tratamento de dados em conformidade com a LGPD. Como objeto de análise, utilizou-se o projeto Datavalid do SERPRO - Serviço Federal de Processamento de Dados, contratado pela Uber, em um cenário hipotético em que o tratamento de dados foi realizado utilizando-se o Hyperledger Fabric.

Abstract (sommario):

Abstract This research project has successfully built a Distributed Ledger Technology (DLT) based prototype using R3 Corda open source. Its purpose applies in the oil & gas underground injection control (UIC) operations for the underground aquifer protection. This DLT prototype is a permissioned network that allows oil & gas companies to create, disseminate, and trace immutable records. The network enables oil and gas companies, government regulatory agency, and all other participants to share secure records such as well information while maintaining data integrity, traceability, and security. The purpose is to create a network of trust among all the stakeholders in the UIC processes for underground aquifer protection. In this DLT network, a company submits well information, which will be digitally signed and notarized. Unauthorized changes to the information, ownership, or history will become infeasible, thanks to the underlying cryptographic technologies of DLT. The network designs so that information stored and communicated will have a high level of trustworthiness. Every participant in the network can get simultaneous access to a common view of the data. Corda platform also provides multiple functionalities, e.g., Smart contract, Vault, Identity Management, Scheduler, Notary Services, etc. Many of the functionalities automate the data processing within the DLT databases. This project's results expect to enhance public safety and improve the aquifer protection review and operational processes. Kern County uniquely poises for a project to develop more streamlined, effective, and entirely digitized DLT-based workflows that will secure regional environmental data integrity. Water contamination is a primary concern in a region where water and petroleum play vital roles in the economy. Both industries and regulatory agencies pay close attention to environmental quality. Data integrity is a primary issue concern for those that monitor and analyze environmental data. Monitoring and forecasting based on available immutable data are imperative to mitigate complications. We have changed the manual workflow into DLT applications which takes advantage of built-in functionalities. The new review process can avoid repetitive reviews among all participants and shorten the approval time. The embedded smart contracts on the DLT network will also help automate the workflows, and therefore, will be able to help eliminate human errors and improve the turnaround time. The prototype model proves the concept of using DLT. Our research work demonstrates DLT successfully implement into energy technology. The prototype model will further expand to all the UIC processes, such as thermal, wastewater disposal, waterflood, gas injection & disposal, etc. It is a substantial cost and time savings for all the oil and gas companies. The results of this analysis could provide the government with valuable information for significant policy and regulation decisions to further benefit the community and society.

Abstract (sommario):

The purpose of this paper is to identify the impact and benefits of the latest information technologies on Accounting Information Systems (AIS). Taking into account the numerous papers related to new technologies and their application in the accounting profession within Industry 4.0, and conducted survey about perception of practitioners in Republic of North Macedonia, this paper summarizes the characteristics and key benefits of some of the new technologies for the functioning of AIS in the digital age. First of all, the evolution of AIS is elaborated, based on theoretical and empirical analysis of the accounting process from the appearance of the first AIS up to nowadays’ services and techniques available for supporting the accounting function. The first technology to be elaborated is Big Data and its potential to change the business landscape, especially in the field of automating operation processes, customer engagements, and predictive decision-making process. Secondly, the Blockchain Technology as an example of Distributed Ledger Technology (DLT), which adoption brings new possibilities in eliminating or redefining the role of entities external to the company. Cloud Computing i.e. Cloud Accounting is the third technology which is elaborated in this paper through the services it offers on the cloud, especially the way AIS process, store and backup the sensitive and confidential data. Last but not least, Artificial Intelligence (AI), a technology that could change the professional services, the need, and opportunities that are provided for a solution to the current accounting issues. In summary, taking into account the relevant literature and the perception of the respondents-practitioners, increased use of these technologies is necessary because their application reduces costs; increases transparency and confidence in information; flexibility, i.e. no time and space restrictions on their use, etc., which is especially useful in the current state of Pandemic, caused by the virus COVID-19.
