The aimof this paper is to review impact of the one of the most modern cutting edge technologies', namely Blockchain on Economic Security. First of all article describes concept - technological background of Blockchain technology nature, emphasizing main features that have most significant and even disruptive impact on separate industries and even whole Economy including Economic Security. Secondly contemporary challenges of this technology are provided. Thirdly multifaced concept of Economic security is explained, followed by importance of this phenomenon specifically within modern mega trends such as Globalization and Information Society. Blockhain impact has been researched through three main industries/functions - eCommerce, Payments and Logistics. Finally conclusions of the paper suggest to use Blockhain with another Industry 4.0 technologies (such as Big Data and Internet of Thing) to reach maximum possible synergy.

This article designed to review impact on Sustainability of the one of the most modern cutting edge technologies‘ namely Blockchain. First of all article describes technological background of Blockchain technology nature and also provides contemporary challenges that this technology faces today. Secondly definition of Sustainability is provided. Thirdly impact level on all 3P‘s has been observed. Justification of the research. Blockchain being one of the most innovative technology nowadays brings solid state of trust between different stakeholders, this technology is extremely useful when we do speak about variety of market players involved in multiple transactions among them, especially when we do speak about value capture, therefore we can expect huge efficiency if we implement it in correct – methodological and systematic order. On the other hand Sustainability is a phenomenon that covers a lot of multifunctional dimensions and brings huge advantages in social sphere such as social responsibility, transparency, efficient usage of resources, compliance to human right, etc. This paper uses definition of Sustainability of John Elkington „Tripple Bottom Line“. Aim is to examine the impact of Blockchain on Sustainability, providing level of that impact on 3 different dimensions – Planet, People, Profit. Methods employed are analysis of the scientific articles, analysis of best practice use cases, comparison, analytical descriptive and generalization methods. Findings of this research support the assumption that Blockchain can essentially contribute to Sustainability due to its technical characteristics – such as decentralized, public/transparent highly reliable register of transactions. Conclusions emphasize Blockchain application in suitable functions with only 2 side comments that the biggest positive results of such implementation can be achieved only after addressing Blockchain challenges and second one is that Blockchain implementation itself generates new generation challenges.

This article aims to review main features and considerations of the one of the most modern cutting edge technologies‘ implementation, namely blockchain in e-procurement. First of all article describes technological background of Blockchain technology nature. Secondly assumptions and pre-conditions of Blockchain application are explained. Thirdly main process and project management methodologies of Blockchain implementation are delivered and separate steps revised. Last but not least as e-procurement (including its part – Supply chain) is a concept consisting of plenty of different processes, therefore for better technology understanding specific advantages per such major different processes are also explained.

This article aims to review economic advantages of the one of the most modern cutting edge technologies, namely blockchain for eProcurement. As eProcurement (including its part – Supply chain) is a concept consisting of plenty of different processes, therefore specific advantages per such major different processes are explained. Assumptions and pre-conditions of Blockchain application are explained. Article‘s main conclusion is that due to the main characteristics of Blockchain technology (safety, transparency, reliability, speed and cost efficiency) payment settlement and products‘ shipping tracking/inventory management are eProcurement‘s phases that could benefit from this technology the most, among others (such as analysis – requirements‘ gathering, sourcing/vendors‘ selection and contract management cycle).

The article object is to is a relatively new research direction in economic theory - economic security at the macro-level. One of the aims of this article is to reveal the country’s economic security idea and to choose methods for this economic phenomenon evaluation as well as to suggest the method to evaluate the energy sector's impact on this economic phenomenon. Firstly, the authors review different approaches to economic security principles and do some assumptions related to the country's economic security concept. There is shortly described the energy sector. Since the scientific problem is how to evaluate the energy sector and the country's security and what impact the energy sector has on the country's economic security, the authors have selected methods to analyze the links between energy sector activities and economic security. Furthermore, there were presented the results of regression analyzes and concluded what energy sector indicators influence countries' economic security.

This article reviews applicability of the very trendy in IT world Agile framework or even mindset and culture (a set of practice that in contradiction to other product and project management practises treats predominantly IT development in very flexible and iterative manner). Research starts with the very foundations of Agile practise, revises its main building blocks (principles) mentioned in primary source – Agile manifesto and examines validity of such principles to be implemented in commercial and business setup, e.g. in commercial relationships between different commercial undertakings. Justification of the research. Agile and agility is very popular nowadays in mainly IT world however due to its nature it is very close to LEAN principles being implemented in manufacturing operations. The main idea behind that mindset is that products have to be developed in iterative mode – closely communicating with the customers and delivering working prieces of functionality as soon as possible (MVP – Minimum Viable Product). Such approach without any doubts is perfectly suitable for internal R&D projects (developing absolutely new products, brainstorming together new ideas), hovewer its full application is doubtful in commercial setup due to the number of reasons. Aim is to examine the applicability of Agile framework in commercial setup, pointing out what and why Agile principles work, and what parts of this mindset can be ignored as non-applicable. Methods employed are analysis of the scientific articles, analysis of best practice use cases, comparison, analytical descriptive and generalization methods. Findings of this research support the assumption that through leveraged Agile practise commercial companies can essentially benefit in designing product‘s quality and speed (time to market). Hovewer some of Agile principles shall be adapted to the nature of commercial relationships by introducing more formal approach to the extent possible (without jeopardizing Agile principles). Conclusions emphasize positive Agility features and recommend to imlement such practises, introducing additional key elements that would ensure formal contractual relationships between commercial undertakings.
