Blockchain: A comparative analysis of hybrid consensus algorithm and performance evaluation

The security of data and information is a critical concern in the rapidly evolving IT industry. Blockchain technology emerges as an innovative way of enhancing data security through the secure transmission of digital assets without a trusted third party or central administrator. Blockchain's fundamental principles of decentralization, immutability, and transparency are applicable in a variety of fields, including finance, supply chain management, healthcare, digital voting, and the Internet of Things. This research explores the underlying protocols of blockchain networks, specifically focusing on consensus mechanisms that enable transaction agreement and validation. The widespread adoption of blockchain technology faces significant challenges in achieving scalability and efficient consensus mechanisms. This research addresses these crucial limitations by proposing a novel hybrid consensus approach designed to enhance usability, security, and scalability. The proposed consensus mechanism incorporates a dynamic difficulty adjustment mechanism. The difficulty of validating blocks dynamically adjusts based on transaction volume and overall validator participation. Furthermore, a slashing mechanism is implemented to penalize validators engaging in malicious behavior by reducing their stake. Our analysis demonstrates the effectiveness of our proposed scheme in addressing several key concerns associated with blockchain, including reducing energy consumption, minimizing the probability of forks, and mitigating the level of mining centralization found in the consensus algorithm.

Nemzetközi Rendészeti Figyelő XIII.

Aim: Keeping up with the international law enforcement literature sometimes runs the risk of bringing together disparate topics in a single publication, as the theme of this issue of the Observer demonstrates. We can be convinced that, while our war-torn planet is giving priority to the centralised state police model, municipal police forces and community policing, which continue to be models at the forefront of strengthening local public security, must not lose their importance. Civil associations, which are an essential part of local security, are not far removed from the principle of decentralisation, and in our country they are embodied in the civil police. At the same time, migration flows, which have become a global phenomenon since 2015, continue to preoccupy the practice of law enforcement administration as well as theory. Only while the former sees illegal migration as a security and cultural threat, the latter cannot forget the humanity-driven protection of refugees. Nor can the fight against terrorism be left off the agenda, especially where these dramatic conflicts are accompanied by the rearrangement of different civilisational cultures. Lastly, the future role of artificial intelligence, for example in areas such as justice, cannot be ignored. Methodology: The authors of the studies primarily rely on empiricism to present the regularities of their research subject, but they also draw on methods tried and tested in the social sciences, especially in sociology, such as interviews and various questionnaires. There is also a lesson to be learned from the fact that the literature, mainly in English, also tries to develop a clear conceptual apparatus, as we have seen in the case of police research in Hungary. Findings: In his review of community policing, Kálmán Etter writes: ‘The publication reveals a specific form of organisation, in which community policing is a group of a few professional police officers and civil servants, operating in individual towns or in the urban areas of larger cities.’ Zsolt Lippai sums up the efforts of citizens to ensure public safety and the tasks of police science: ‘The increasing involvement of non-state actors in the creation of security and the use of methods other than those traditionally used in what might be called “traditional” policing have given rise to a number of theoretical and practical questions which police researchers are called upon to answer.’ Bernadett Bacsó draws attention to a little-studied consequence of migration: ‘In recent years, migration, especially migration driven by young men, has changed the gender balance in destination countries, as this trend leads to a lack of potential female partners.’ The main aim of the study was to build a picture of what Americans think about current issues such as national security, terrorism, counter-terrorism policies, immigration and religion. Tamás Pressburger cites the perceptions of US citizens about terrorism, but also what motivates these views: ‘Based on the experiment, the author concludes that when white subjects are informed that whites are projected to become a demographic minority in the United States by 2060, they are more likely to endorse the use of torture against suspected terrorists.’ Katalin Erdélyi's review highlights the controversial role of artificial intelligence (AI) in the administration of justice: ‘The author's conclusion in this excellent article is that the coexistence of AI and human judges risks a covert transfer of decision-making power.’ It could also be argued that the computer cannot take over the formation of internal judicial convictions because only humans can do that. Value: The modern rule of law makes humanity a core value. The studies to which issue XIII of the Observer draws attention, not infrequently accompanied by concern, represent this value system.

Pembentukan Daerah Otonomi Baru: Pemekaran Provinsi Kepulauan Nias

Indonesia adheres to the principle of decentralization in administering its government. Each region has the right and is given the authority to manage its own government affairs. The granting of broad autonomy to the regions is directed at accelerating the realization of social welfare through service improvement, community empowerment and participation. Law No. 23 of 2014 wants the birth of a new autonomous region in Indonesia. The implementation mechanism is further regulated in Government Regulation No. 78 of 2007. Expansion of regions is one of the efforts to accelerate national development. The conditions that must be met in the expansion of the new autonomous regions include: 1) basic territorial requirements; 2) regional capacity requirements; and 3) administrative requirements. The Nias Islands are an area that has been planned to be split into a new autonomous region. The research method used is empirical juridical, namely research conducted to analyze the implementation of legal norms that apply in society. Discussions regarding the plan for regional division of the Nias Islands have started since 2009 but until now there has been no realization from the central government. The obstacle to the expansion of the division is the existence of a moratorium set by the President. Regional expansion is also considered to be a burden on state finances considering that apart from the Nias Islands, there are still many other regions that have also proposed to do division. However, when an area meets the requirements for expansion as stipulated in Government Regulation No. 78 of 2007 and there is an urgency why the area must be divided immediately. It is better if the moratorium is lifted so that each region that has met the requirements to carry out expansion can become a new autonomous region and become more developed because it is given the authority to manage its own region.

Cities in transition: Krakow‘s social, economic and spatial transformation within the last thirty years (selected aspects)

Krakow is a city that has undergone an immense transformation in recent years. At the end of the 1980s, the period of communism ended and Polish local governments began to operate based on the principles of subsidiarity, decentralisation and independence. In 2004, Poland joined the European Union, which opened up new prospects for development, including in regional and local terms. The world has become a networked and digitized entity susceptible to the influence of innovation. Due to metropolitisation processes, cities, especially those offering above-average earnings, a diversification of economic resources and a relatively high quality of life, began to develop even more dynamically, which had and still has negative consequences. In Poland, there are five cities in which development dynamics have a highly specific dimension. Apart from the capital city of Warsaw, these are Krakow, Wrocław, Poznań and the agglomeration of the so-called Tri-city (Gdańsk, Sopot and Gdynia). The aim of this study is to show how Krakow, the second-largest city in Poland, has evolved over the last three decades at the level of demographics, urban development and economy; how it changed in the historical “milestones” indicated above. Therefore, depending on the availability of statistical data, several time periods were selected and compared with each other in the most important areas of Krakow’s functioning. The research hypothesis is as follows: Krakow’s development policy in key areas optimally uses the opportunities resulting from contextual conditions (social, economic and cultural changes that have taken place in recent decades). The study focuses on the three main problems of the city’s development (the abovementioned key areas of the city’s functioning and development): socio-demographic, spatial and economic changes. The analysis assessed data from the literature, city reports and other available sources, as well as public quantitative data (assessment of data from the National Census for the years 1988, 2002, 2011, 2022; Local Data Bank of Statistics Poland and otherrepositories and reports).

The Mayor of Batam Ex-Officio as Head of The Batam Concession Agency: Cross-Jurisdictional Authority and Legal Problems

<em><span><span lang="EN-US">This research aims to explore the impact of granting the position of Head of the Batam Concession Agency to the Mayor of Batam on an ex-officio basis on the principle of "check and balance" in the governance of Batam and to assess the extent to which this policy is consistent with the principles of regional autonomy and decentralization, which are constitutional cornerstones in Indonesia. Through a normative legal research method using secondary data, this study reveals that the policy of granting ex-officio positions has a significant impact on the principle of "check and balance" with a potential reduction in the effectiveness of internal and external supervision, as well as an increased potential for abuse of power that may affect the integrity of decision-making. In addition, this policy raises essential questions about consistency with regional autonomy and decentralization principles, the main pillars of Indonesia's governance system. The principle of regional autonomy aims to give authority to local governments to manage their affairs without excessive interference from the central government. This research provides important insights into the consequences and consistency of government policies that may affect the fundamental principles of regional governance.</span></span></em>

Research on Blockchain-Enabled Smart Grid for Anti-Theft Electricity Securing Peer-to-Peer Transactions in Modern Grids.

Electricity theft presents a significant financial burden to utility companies globally, amounting to trillions of dollars annually. This pressing issue underscores the need for transformative measures within the electrical grid. Accordingly, our study explores the integration of block chain technology into smart grids to combat electricity theft, improve grid efficiency, and facilitate renewable energy integration. Block chain's core principles of decentralization, transparency, and immutability align seamlessly with the objectives of modernizing power systems and securing transactions within the electricity grid. However, as smart grids advance, they also become more vulnerable to attacks, particularly from smart meters, compared to traditional mechanical meters. Our research aims to introduce an advanced approach to identifying energy theft while prioritizing user privacy, a critical aspect often neglected in existing methodologies that mandate the disclosure of sensitive user data. To achieve this goal, we introduce three distributed algorithms: lower-upper decomposition (LUD), lower-upper decomposition with partial pivoting (LUDP), and optimized LUD composition (OLUD), tailored specifically for peer-to-peer (P2P) computing in smart grids. These algorithms are meticulously crafted to solve linear systems of equations and calculate users' "honesty coefficients," providing a robust mechanism for detecting fraudulent activities. Through extensive simulations, we showcase the efficiency and accuracy of our algorithms in identifying deceitful users while safeguarding data confidentiality. This innovative approach not only bolsters the security of smart grids against energy theft, but also addresses privacy and security concerns inherent in conventional energy-theft detection methods.

FORMATION OF THE COST SYSTEM BASED ON THEIR OPTIMAL STRUCTURE

The functioning of business entities of the machine-building industry is closely related to the consumption in the process of manufacturing and selling products (goods, services) of a wide range of material, energy, labor, financial, and intellectual resources. Accordingly, the amounts incurred by the enterprise constitute a generalized monetary estimate of the cost of consumed production resources, and also reflect the optimal use of resources, the consumption of which is important for providing all the needs of the enterprise at the stage of production processes. Effective management influence at the stage of formation and implementation of expenses requires ensuring an equally significant degree of differentiation of the defined management system, as well as the justified application of norms and methods of solving management problems related to the optimal regulation of consumption norms. The basis of the integrated cost management system is a hierarchical system of performance indicators of the enterprise, which provides an opportunity to implement the principle of decentralization in the implementation of management decisions. The budgeting system creates prerequisites for attracting additional financial resources, finding channels for their mobilization, adequate centralization of cash flows, and regulates their rational use. The proposed algorithm for implementing an integrated cost management system is shown in Fig. 3.6. determines the procedure for implementing a set of systematized measures regarding the implementation of management technology, the system of intra-firm cost planning, which prescribes key regulations and management procedures.

Some aspects of legal regulation of cryptocurrency circulation in Ukraine

The impact of modern information technology has led to the emergence of a new form of currency – cryptocurrency, based on blockchain technology. This study aims to analyze the existing legal framework and delve into potential ways of legal regulation of activities related to the circulation of cryptocurrencies, in particular bitcoin. To achieve this goal, the study used a comprehensive set of both general scientific and specialized cognitive methods, including the comparative legal method, the systemic and structural method, methods of generalization, analysis and synthesis.
 The study clarifies the essence of blockchain-based cryptocurrencies as an alternative to traditional fiat currencies based on the fundamental principle of decentralization. It is noteworthy that among the many cryptocurrencies, bitcoin stands out with a distinctive feature called “hardness,” which gives it the properties of “digital gold.” This quality makes bitcoin a powerful means of preserving value, like precious metals, strengthening its status in global finance.
 In addition, the study outlines the current state of legal regulation of relations related to the circulation of virtual assets. A thorough analysis of the existing legal framework and its effectiveness in addressing the unique challenges posed by decentralized currencies has also been conducted.
 The study pays considerable attention to the prospects for the development of legal regulation of cryptocurrencies, which will consider the dynamic nature of virtual assets.
 To summarize, this study contributes to the understanding of the economic intricacies inherent in blockchain-based cryptocurrencies, with a special emphasis on the “hardness” of bitcoin as a distinguishing factor. In addition, the study sheds light on the current state of legal regulation of virtual assets, paving the way for insightful predictions of the future regulatory landscape. This work not only adds to the academic discourse around cryptocurrencies, but also serves as a valuable resource for policymakers, practitioners and academics grappling with the challenges and opportunities presented by this new financial paradigm.

Norwegian perspectives on health care for people with intellectual and developmental disabilities

AbstractThe Norwegian health care system is built on individual rights and the principles of universal access, decentralization, and free choice of provider. Norway has universal health coverage, funded primarily by general taxes and by payroll contributions shared by employers and employees. Local authorities at the municipal level organize and finance primary health care services according to local demand and within national frameworks. Habilitation services are offered both in the primary health care and as a part of the specialist health services. They offer both inpatient and outpatient services for people with intellectual/developmental disabilities (IDD). National guidelines, known as Good health and care services for people with IDD, have recently (2021) been launched after various reports over the years of serious breaches and challenges in the health and care services provided to people with IDD.

КРЕАТИВНЕ ЛІДЕРСТВО В ОРГАНАХ ДЕРЖАВНОЇ ВЛАДИ: МЕНЕДЖМЕНТ-МАРКЕТИНГОВИЙ ПІДХІД

The article deals with the theoretical and methodological trends of leadership in the conditions of martial law, the influence of leadership qualities on digitization and their advantages in modern society. The need to activate the creative basis of business structures is substantiated. The essence of creativity in the general sense and in the production activity of the enterprise is clarified. The need to activate the creative basis of business structures is substantiated. The essence of creativity in the general sense and in the production activity of the enterprise is clarified. The role of the manager in the development of creativity at the enterprise is determined, taking into account the main features that contribute to leadership in creative management. The necessary measures to stimulate the development of creativity and creative abilities of employees are formulated, the factors that contribute to the formation of creative activity of personnel and important conditions for the success of innovative activities in the management of business structures are highlighted. When choosing a management style, the leader must take into account, first of all, the laws of management, which determine the basis of the objective components of the style. Ignorance of laws can only partially be compensated by the art of management. The same applies to the principles (generality, objectivity, obligation) that determine the rules for introducing laws into management practice, serving as guidelines when choosing a style. Today, the principle of decentralization is manifested by democratic leaders during the organization of the implementation of the decisions made. It is implemented in the form of delegation of authority by the leader to subordinates. At this stage, a democratic leader tries to take into account the level of professional training, experience, ambitions, motivation, etc. of his followers as much as possible. By delegating responsible duties to them, he strives to make their performance attractive, satisfying and conducive to personal growth, while achieving success serves as a kind of social reward, strengthens the sense of involvement and personal responsibility for the fate of the organization. Along with responsibilities, the leader delegates to his followers the appropriate authority and resources to fulfill them. Without removing his own responsibility for achieving the defined goals, the leader in the framework of the democratic style of management avoids excessive detailed control over the actions of subordinates. He controls the result, giving subordinates the opportunity to show creativity when determining ways to achieve it. However, when evaluating subordinates, he is guided by objective, tested and well-known criteria that exclude subjectivism or bias.

Нетипичные формы государственного устройства: на примере империи

In the science of the theory of state and law, a problem related to the classification of forms of state structure has arisen. The traditional approach to the form of state structure, within which it is customary to distinguish unified (unitary) and constituent (federal) states, does not reflect contemporary life realities. There are no clear criteria in legal science for dividing states into unified and constituent ones. The paper considers various approaches to the problem of classifying forms of state structure in contemporary legal theory. The author concludes that the traditional three-element approach to the form of state (form of government, form of organization and political regime) has methodologically exhausted itself and does not reflect the current state of affairs. All elements of the state form are closely interrelated and are in an unbreakable dialectical unity. The form of government largely determines the form of the territorial structure, as well as the methods of interaction between the authorities and the population (political regime). The nature of the relationship between the center and the regions (constituent entities) based on the centralization or decentralization principle, largely depends on the form of government. As a rule, the republican form of government determines the federal (decentralized) form of state-territorial structure and the democratic political regime. At the same time, the real possibility of functioning of republican institutions (election and alternation of government authorities) and the implementation of the federalism principles (the actual independence of the constituent parts of the state) largely depend on the political regime. In the context of an authoritarian (totalitarian) political regime, the republican form of government and the federal form of government enshrined in legislation are conditional in nature – in fact, they cannot be implemented. The purpose of the work is to analyze the forms of state structure in contemporary legal theory and identify the essential features of empire as a special form of state structure.

OPTIMALISASI PERAN PEMERINTAH DAERAH DI BIDANG PELAYANAN KESEHATAN BERDASARKAN ASAS RESPONSIBILITAS

Regional Government is one of the elements of government that supports the implementation of regional government. To run regional government, it is carried out by optimizing the role of regional government, especially in the implementation of government affairs, both absolute government affairs, concurrent government affairs and mandatory government affairs. One of the government affairs in this article is related to health services which are part of concurrent government affairs. Concurrent government affairs are regional government affairs which are carried out based on the principle of regional autonomy by prioritizing the principles of decentralization, deconcentration and assistance tasks. It should be noted that in implementing regional autonomy, regional governments are obliged to prioritize services using the principles of good governance. In this case, the author is interested in discussing What are the legal regulations regarding health services as part of regional government affairs? And how to optimize the role of local government in the field of health services by prioritizing the principle of responsibility? Because as is known, based on the principle of responsibility, the government must comply with laws and regulations and carry out responsibilities towards society and the environment so that it can run well and the government can be managed well and correctly. In this research, the author uses a legal concept approach and a statutory regulations approach which will examine how regional governments implement the principle of responsibility in accordance with the provisions of statutory regulations and also regional policies based on the principle of regional autonomy.Keywords: Good Governance; Regional autonomy; Responsibility.

Konsepsi Otonomi Daerah Dalam Pola Relasi Mandala Kedatuan Sriwijaya

The Srivijaya Kingdom, in its historical journey, showed a strong commitment to giving more independence to the regions under its control. This meant that these regions could manage their own local matters, taking into account their unique characteristics. This idea played a vital role in boosting the economy and stability of the entire kingdom, making the "kadātuan" system a crucial part of their successful government. The principles of decentralization in Indonesia, based on these historical ideas, have been incorporated into changing laws and regulations, forming a key part of how different areas in Indonesia govern themselves. This paper aims to explore how the concept of local government or decentralization worked in the Srivijaya Kingdom's history. We use a qualitative method that helps us understand complex ideas. By comparing modern decentralization ideas with how the Srivijaya Kingdom managed its decentralization using a "mandala" structure, we see important similarities and connections between the two. The results in this paper show a historical pattern where decentralization were set up and led by a datu. This allowed powers to be shared from the central government to these decentralization regions, which were closely supervised by the central government. This reveals how the idea of decentralization has deep roots in Indonesia's history and is a critical basis for how decentralization works in the country today.

Penegakan Hukum Terhadap Pelanggar Penggunaan Kendaraan Dinas

Law Enforcement supervision of violators of official vehicle users by government officials is carried out based on the principle of decentralization where the Central Government fully delegates to Regional Governments to follow up or manage their respective regions. Any State/regional losses due to negligence, misuse or violation of law on the management of State/regional property are resolved through claims for compensation in accordance with laws and regulations. In responding to and avoiding the misuse of official vehicle facilities by government officials, it is necessary to supervise the use of official vehicle facilities. Supervision carried out on official vehicle facilities is intended so that government officials are aware of their responsibilities as servants of the state and society and do not attach importance to personal interests. The legal issues in writing are, first; What is the function of Government supervision of official vehicles ?. second; How are sanctions applied to violators of the use of official vehicles by government officials? The type of research used is Normative juridical research using a problem approach, namely a statutory approach and a concept approach. While the legal materials used are primary legal materials, secondary legal materials and tertiary legal materials. The technique of collecting legal materials through literature research with legal material analysis techniques is qualitative. Based on the results of research that violations of the use of official vehicle functions are still often encountered, due to the use of official vehicles are often used outside official interests. Violation of regulations and abuse of authority because it is not in accordance with the use and function of the official vehicle itself based on Government Regulation Number 28 of 2020 on Amendments to Government Regulation Number 27 of 2014 concerning Management of State/Regional Property and in accordance with Government Regulation Number 94 of 2021 concerning Civil Servant discipline. Government officials who misuse official vehicles may be penalized. Any party that causes losses to the State/Region for personal interests or for interests outside the functions of the position and service that can result in state/regional losses, may be given administrative sanctions and criminal sanctions.

A Study on Secured Unmanned Aerial Vehicle-Based Fog Computing Networks

<div>With the recent advancement in technologies, researchers worldwide have a growing interest in unmanned aerial vehicles (UAVs). The last few years have been significant in terms of its global awareness, adoption, and applications across industries. In UAV-aided wireless networks, there are some limitations in terms of power consumption, data computation, data processing, endurance, and security. So, the idea of UAVs and Edge or Fog computing together deals with the limitations and provides intelligence at the network’s edge, which makes it more valuable to use in emergency applications. Fog computing distributes data in a decentralized way and blockchain also works on the principle of decentralization. Blockchain, as a decentralized database, uses cryptographic methods including hash functions and public key encryption to secure the user information. It is a prominent solution to secure the user’s information in blocks and maintain privacy. The ongoing development in collaborative UAVs and fog computing networks had put further a major challenge of security that need to be investigated. This article presents a study on security attacks and requirements needed to ensure security in UAV-based fog networks. We provide blockchain security in UAV-based fog computing to secure a large volume of data. The communicated data is stored in the form of blocks with hash functions, which guarantee security in the network. Thus, the aim of blockchain security is to guarantee that any hostile third party cannot corrupt or change the live missions or tasks allocated to actual UAV–Fog nodes.</div>
