Cryptocurrency and Blockchain

As the technologies are evolving day by day, they are able to rejuvenate any sector either individually or by incorporating other technologies. There are many prominent sectors in the market such as healthcare, education, entertainment, business, information technology, retail, etc. Every sector has its own set of profits and consequences, but apart from all, the banking or finance sector is the only sector that provides dynamicity to all other sectors and helps them to generate maximum revenue from their principal investment. In this chapter, the authors are focusing on the traditional and modern ways of banking, currencies such as cryptocurrency like Bitcoin, Ethereum, Litecoin, and how the modern currency will change the transaction procedure in the global banking system, creating an amalgamation of such currency with a current transaction system with the role of technology such as Blockchain in the betterment of the global banking system making the system fully decentralized, distributed, transparent, fast, immutable, and efficient.

Transaction fee mechanism design

Demand for blockchains such as Bitcoin and Ethereum is far larger than supply, necessitating a mechanism that selects a subset of transactions to include "on-chain" from the pool of all pending transactions. EIP-1559 is a proposal to make several tightly coupled changes to the Ethereum blockchain's transaction fee mechanism, including the introduction of variable-size blocks and a burned base fee that rises and falls with demand. These changes are slated for deployment in Ethereum's "London fork," scheduled for late summer 2021, at which point it will be the biggest economic change made to a major blockchain to date. This short note provides an overview of recent work by the author that formally investigates and compares the incentive guarantees offered by Ethereum's current transaction fee mechanism and the new mechanism proposed in EIP-1559.

Increasing the Indonesia's Tourism Sector to be more Competitively

Currently and in the future, Indonesia is still said to be very dependent on tourism to cover the current transaction deficit and the state budget deficit. The obstacle that must be overcome by the government and tourism business actors is achieving the target of foreign tourists visiting Indonesia. Therefore, this discussion is to Increasing the Indonesia's Tourism Sector to be more Competitively.

Rancang Bangun Automatic Smart Energy Meter Berbasis RFId

The development of technology today makes it easier for humans in their daily activities. One of them is in the digital world. In the industrial era 4.0. more and more companies are issuing breakthrough new products based on digital technology that aim to be practical in their use. One of the technologies applied is the use of smart cards. For example in the use of smart keys in homes and car doors. Then in the current transaction process, many have implemented this smart card technology. The purpose of this research is to apply the latest technology in the energy transaction process which will be applied to the KWh meter. The smart card used is RFId and is integrated in the database and website so that its use is more practical and flexible. Then the use of this smart card can be applied to the smart energy meter so that later the prepaid energy transaction process can be applied easily with this smart energy meter.

Blockchain technology in commercial real estate transactions

Purpose The transaction process of an office building is known to be time consuming and inefficient, in part due to the lack of market transparency. The purpose of this paper is to focus on the development of a blockchain application that can improve the transaction process of office buildings in the Netherlands. Design/methodology/approach Conducting design science research, the current transaction process of an office building and status quo of blockchain technology in real estate is investigated. Subsequently, multiple parties are interviewed to define major pain points within the process. The interview findings are used to design a blockchain solution which overcomes the aforementioned pain points. After designing, the interviewees are asked again to pragmatically validate the proposed model. Findings One of the major pain points identified concerning the transaction process of an office building is that it is difficult to define the characteristics of a property, due to lack of data structure and quality. The proposed application improves the way specific assets are understood by structuring physical and contractual information in one place and guarantees the quality of the data by using the blockchain mechanisms. Practical implications A blockchain application is proposed, which can improve the transaction process of an office building. Originality/value Recent studies indicate that blockchain technology could lead to improvements in efficiency, transparency and therefore trust within the transaction process. Therefore, the proposed application is of value for the future of real estate data management and the transaction process.

A Mobility Link Service for NDN Consumer Mobility

Named Data Networking (NDN) supports the consumer mobility service by letting a consumer reissue an interest. This method is straightforward, but it may cause several drawbacks, including unnecessary handover overhead and long handover delay. We concentrate on the NDN communication model in which the pair of an interest and a data packet is considered a single communication working set (i.e., transaction unit). In this respect, reissuing an interest means creating a new transaction due to the connection damaged by the movement of a consumer. It makes all states of the current transaction useless, and this is where the drawbacks arise. In order to enhance the consumer mobility service, we propose Mobility Link Service (MLS) operated in NDN face which is responsible for management of a connection for a transaction. MLS reuses the existing states of a transaction by establishing a connection for the transaction instead of creating a new one. In addition, MLS in NDN face makes consumer mobility service transparent to the NDN forwarding plane. Therefore, the consumer mobility service and the NDN architecture can evolve independently. The performance evaluation shows that MLS reduces the amount of retransmitted data and handover latency compared with the existing NDN mobility solution.

The domestic resource gap and current transaction deficit in Indonesia in 2010-2014

The purpose of this study is to determine the relationship between domestic financial resource gaps and current account balance in Indonesia by using data from 2010 to 2014. Gaps in the domestic economy are classified into three types: 1) the domestic absorptive capacity of the national income gap (GNP), 2) gross national savings and investment gap, 3) private sector gap (private saving minus private investment), and public sector gap (tax minus government spending). By using a concept of open economy that is described in a theoretical framework, the study results show that: 1) the gap absorption of domestic and GNP, 2) the gap between gross national saving and gross national investments, 3) the gap in private sector and government sector resulting in deficit in the current account during Indonesia on 2010-2014 periods.

HUBUNGAN KAUSALITAS DEFISIT NERACA TRANSAKSI BERJALAN DENGAN KURS DI INDONESIA

This research is aimed at understanding the relation pattern of the current transaction balance and Indonesian rate of exchange in 1981-2002. The analysis method used is Granger causality method. Yet, before doing the Granger causality test, it was carried out data stationary test to avoid fake correlation. Stationary test shows that the data are not stationary so that it was made stationary by using one different level. The result of Granger causality analysis shows that it happen only one direction causality relation from the deficit of current account towards the rate of exchange because it has smaller counting F value then the determined a.

The Mechanism Design to Direct Power-Purchase Transaction Considering Market Supply and Demand

At present, direct power-purchase for large consumers is difficult to carry out effectively when demand exceeds supply. Interest demand of direct power-purchase for large consumers under different conditions of supply and demand is analyzed in this paper. Therefore, design principle of transaction mechanism for direct transaction adapting to different supply and demand situation is also applied. The purpose is striving to carry out the direct transaction effectively when market demand exceeds supply situation, adjusting the supply and demand and solving the "soft lack of electricity" phenomenon due to fluctuation of coal price. In the end, some suggestions are put forward to the current transaction rules.
