The creation of cryptocurrencies marked the beginning of a new era in money evolution. In the cryptocurrency system, governments do not have primacy over monetary flows, but it is in the hands of participants in the cryptocurrency system, which enables the democratization of money. This also raised a number of issues that need to be resolved. Among them, the issues of incorporating cryptocurrencies into monetary policy, accounting, and tax treatment of cryptocurrencies, as well as preventing potential abuses, are especially prominent. On the other hand, Shariah experts deal with cryptocurrencies from the aspect of their Shariah compliance, and on that issue they are divided. This paper analyzes the treatment of money in Islamic teaching and practice, the concept of cryptocurrencies, and the challenges of their practical application, as well as the arguments presented by Shariah experts in support of their positions on the Shariah (non)compliance of cryptocurrencies.

Modern application of the blockchain technology is the center of attention of technology and economy sectors. Proper usage of blockchain is based on peer to peer (P2P) network to coordinate a worldwide, universal ledger where all transactions on the network are recorded. In order to provide security and veracity of ledger system blockchain systems uses cryptographic hash function. By hashing the block sent by the member of P2P network and checking if it still fits the pattern for the next block, the network can easily prove that the calculating machine did in fact find coded solution of function. Before adding data received on this way majority of the machines on the network must provide consensual confirmation of transaction. this confirmation must be confirmed with at least 51% of machines in the system. This is first and most analyzed vulnerability of this type of ledger systems

Islam attaches great importance to insurance, as an instrument of protection of the individual and the community, and considers it an indispensable element of the process of achieving socio-economic justice in society. Consequently, in the Islamic concept of insurance, the social component dominates over the commercial component. However, requirements of the modern environment have made it necessary to have Shariah-acceptable commercial insurance. Given that conventional insurance models are largely Shariah non-compliant, Takaful insurance has been developed to meet the needs of individuals and institutions that want to be insured in accordance with Shariah principles. In this paper, we will analyze the process of evolution of Takaful insurance, its types and models, perform a comparative analysis of Takaful and conventional insurance, reviewing arguments in favor of Shariah specific nature of conventional insurance, and finally, list the challenges of implementing Takaful insurance in practice.

The aim of the research is to measure the actual level of satisfaction of the domestic banks clients with the internet banking services and to determine the connection between satisfaction and internet banking and its main determinants. The research was conducted through a questionnaire, and 193 respondents took part. The obtained answers were processed using descriptive static analysis, reliability analysis of research variables, correlation analysis, and multivariate regression analysis. By analyzing the relevant literature, efficiency, safety and privacy, accessibility, response and costs were determined as independent variables, while satisfaction was used as a dependent variable. The research results show that the strongest influence on the bank clients satisfaction has the efficiency factor, followed by the response, security, and privacy, while accessibility and costs do not have a statistically significant impact on the internet banking users satisfaction.
