Blockchain could be called a string of blocks that acts like a ledger that is also distributed. Members in a defined P2P network are given access to the blockchain and can create new blocks. When the data is stored in a blockchain, changing it becomes virtually impossible. The data stored within blocks is timestamped to avoid tampering. Blockchain has applications in numerous fields like IoT, digital currency, financial services, reputation systems, smart contracts, security services, etc. If any virtual or real asset transaction is happening online, blockchain technology can be easily applied to optimize and secure the transaction better. Blockchain-based applications bring controversies, and yet many exceptional and diverse use-cases have been found for blockchain in both financial and non-financial sectors. Although it holds immense promise, it doesn't come without risks and uncertainties. This chapter elucidates the growing risks and uncertainties which accompany the use of blockchain in automated systems.

The Right

Blockchain which includes smart contract and tokenization features is the latest technology in the world, especially Indonesia. Smart contracts and tokenization make it very easy for users and can maintain valid data security, but there are still many universities that have not implemented the system so they have to involve many parties and costs. The problem taken in this study is the payment process for transactions such as credit and data processing that is vulnerable to illegal data leakage. This study aims to develop a smart contract system and blockchain tokenization in universities in the payment transaction process. The method used in this research is literature review analysis and testing method. The implementation of smart contracts and tokenization can replace third parties as security guards of transaction data with all Blockchain users paying attention and ensuring the integrity of the entire process and activity. This of course can avoid problems that arise from the presence of third parties in the transaction process. So it can be concluded that the implementation of smart contracts and Blockchain tokenization in payment transactions is the right solution to be applied in the payment transaction process at universities.

Abstract Objective Although patient generated health data (PGHD) has stimulated excitement about its potential to increase patient engagement and to offer clinicians new insights into patient health status, we know little about these efforts at scale and whether they align with patient preferences. This study sought to characterize provider-led PGHD approaches, assess whether they aligned with patient preferences, and identify challenges to scale and impact. Materials and Methods We interviewed leaders from a geographically diverse set of health systems (n = 6), leaders from large electronic health record vendors (n = 3), and leaders from vendors providing PGHD solutions to health systems (n = 3). Next, we interviewed patients with 1 or more chronic conditions (n = 10), half of whom had PGHD experience. We conducted content analysis to characterize health system PGHD approaches, assess alignment with patient preferences, and identify challenges. Results In this study, 3 primary approaches were identified, and each was designed to support collection of a different type of PGHD: 1) health history, 2) validated questionnaires and surveys, and 3) biometric and health activity. Whereas patient preferences aligned with health system approaches, patients raised concerns about data security and the value of reporting. Health systems cited challenges related to lack of reimbursement, data quality, and clinical usefulness of PGHD. Discussion Despite a federal policy focus on PGHD, it is not yet being pursued at scale. Whereas many barriers contribute to this narrow pursuit, uncertainty around the value of PGHD, from both patients and providers, is a primary inhibitor. Conclusion Our results reveal a fairly narrow set of approaches to PGHD currently pursued by health systems at scale.

This article using critical analysis discusses the legal status of smart contracts, their features and characteristics, and the possibility of introducing this category into the legal field. The main goal of the study is to determine the legal status of smart contracts. The study concludes that a smart contract is a program code based on blockchain technology, which, by legal characteristics, is a legally significant message recorded in a language (artificial language) and sealed with an electronic digital signature of each of the parties (or certified with a special key). It is proved that the multilateral interactions implemented through smart contracts can reduce the costs of operations and control them, increase the speed of operations and reduce the risks associated with dishonest actions of the parties, minimize or completely exclude intermediaries from the transaction; therefore, legislation should provide for the possibility of using smart contracts along with existing contracts.

The development of information technology and computer network from time to time is increasing along with the increase in user needs for both from the business, education, industrial, to data security side. Data of network traffic that is getting denser in communication and data exchange between users on computer networks can become a problem when using conventional computer network technology. For that, it needs a new technology that is implemented in computer networks, along with the measurement of Quality of Service (QoS) in it. Software-Defined Networking (SDN) is a solution for this, where the stages of network design, management and implementation, separate the data plane and the control plane. In this research, the implementation of SDN was carried out in the form of a simulation using both of Mininet and OpenDaylight with a Tree Topology, then the QoS measurements were carried out in it. The results of testing and measuring QoS on SDN simulations with Tree topology using Mininet and OpenDaylight, showed a Jitter value of 0.425 ms, a Packet Loss value of 0.266%, a Bandwith value of 9.3925 Mbps, a UDP Throughput value of 2.348 bits/sec, and a TCPThroughput value of 2.335 bits/sec.
