Integration of blockchains with management information systems

In the era of the fourth industrial revolution (Industry 4.0), many Management Information Systems (MIS) integrate real-time data collection and use technologies such as big data, machine learning, and cloud computing, to foster a wide range of creative innovations, business improvements, and new business models and processes. However, the integration of blockchain with MIS offers the blockchain trilemma of security, decentralisation and scalability. MIS are usually Web 2.0 clientserver applications that include the front end web systems and back end databases; while blockchain systems are Web 3.0 decentralised applications. MIS are usually private systems that a single party controls and manages; while blockchain systems are usually public, and any party can join and participate. This paper clarifies the key concepts and illustrates with figures, the implementation of public, private and consortium blockchains on the Ethereum platform. Ultimately, the paper presents a framework for building a private blockchain system on the public Ethereum blockchain. Then,integrating the Web 2.0 client-server applications that are commonly used in MIS with Web 3.0 decentralised blockchain applications

Combining Blockchain and Swarm Robotics to Deploy Surveillance Missions

Current swarm robotics systems are not utilized as frequently in surveillance missions due to the limitations of the existing distributed systems\u27 designs. The main limitation of swarm robotics is the absence of a framework for robots to be self-governing, secure, and scalable. As of today, a swarm of robots is not able to communicate and perform tasks in transparent and autonomous ways. Many believe blockchain is the imminent future of distributed autonomous systems. A blockchain is a system of computers that stores and distributes data among all participants. Every single participant is a validator and protector of the data in the blockchain system. The data cannot be modified since all participants are storing and watching the same records. In this thesis, we will focus on blockchain applications in swarm robotics using Ethereum smart contracts because blockchain can make a swarm globally connected and secure. A decentralized application (DApp) is used to deploy surveillance missions. After mission deployment, the swarm uses blockchain to communicate and make decisions on appropriate tasks within Ethereum private networks. We set a test swarm robotics system and evaluate the blockchain for its performance, scalability, recoverability, and responsiveness. We conclude that, although blockchain enables a swarm to be globally connected and secure, there are performance limitations that can become a critical issue

Using Blockchain Technology in Smart Life Applications

مقدمة: Blockchain هي قاعدة بيانات يتم تخزينها بترتيب زمني بطريقة آمنة ومستقرة. كانت Bitcoin هي التطبيق الأولي لتقنية Blockchain ، ولكن نظرًا لفوائدها من حيث الأمان والخصوصية والتحكم الذاتي ، فقد تم اعتمادها منذ ذلك الحين من قبل مجموعة متنوعة من التطبيقات. يتم إنشاء تقنية Blockchain عن طريق ربط الكتل معًا بشكل مشفر. نظرًا لأن كل كتلة تحتوي على كلٍ من التجزئة الخاصة بها وتجزئة الكتلة السابقة لها ، فلا يمكن لأي شخص خارجي كسر السلسلة. تُستخدم تقنية Blockchain ضمن مجموعة متنوعة من التطبيقات ، بما في ذلك الصناعية والتجارية والأمنية وسلسلة التوريد وإنترنت الأشياء وغيرها. هذا لأنه يتميز بمزايا التحكم في البيانات وتنظيمها وتخزينها. الغرض من هذه المقالة هو سرد بعض التطبيقات ومجالات التطوير الخاصة بـ Blockchain.   طرق العمل: في تقنية Blockchain ، يعد الأمان والاستقرار (الثبات) واللامركزية من بين الأشياء المهمة التي تجعل هذه التقنية مفيدة في مختلف مجالات الحياة التي تخدم المستخدم. تم استخدام هذه المزايا لحل العديد من المشكلات التي تواجه الشبكة ، بما في ذلك المشكلات المتعلقة بالإنتاجية ووقت المعالجة وقابلية التوسع. تم استخدام طرق مختلفة في الحل ، بما في ذلك العمل على تغيير هيكل الشبكة ، واختيار عقدة أساسية (المدير) ، والتعدين الموازي ، والتنافس مع عمال المناجم الآخرين. الاستنتاجات: ازداد الميل إلى استخدام تقنية Blockchain في العديد من المجالات ، بما في ذلك المالية والزراعية والتجارية والصحية وإنترنت الأشياء وغيرها ، نظرًا لمزاياها ، بما في ذلك اللامركزية والتوزيع والموثوقية والاستقرار. هناك اتجاهات أخرى عملت على تطوير أداء وكفاءة وأمان نظام Blockchain نفسه في إنترنت الأشياء والرعاية الصحية وسلسلة التوريد والقطاع المصرفي والتسويق الرقمي بالإضافة إلى الدراسات التي تشمل تحسين الكفاءة والأمان وتطوير النظام.Background: Materials and Methods:      In Blockchain technology, security, stability (immutability), and decentralization are among the important things that make this technology useful in various areas of life that serve the user. These advantages were used to solve many problems facing the network, including those of productivity, processing time, and scalability. Various methods were used in the solution, including working on a change in the network structure, choosing a basic node (the manager), parallel mining, and competing with other miners. Results:     Through recent studies, it has been shown that the Blockchain technology has been used in various fields, as it is characterized by many advantages, the most important of which are security, decentralization, and stability. Because of these advantages, it outperforms other technologies. Conclusion:     Due to its advantages, the tendency to use blockchain technology has increased in many fields, including financial, agricultural, commercial, health, the Internet of Things, and others. It includes decentralization, distribution, reliability, and stability. There are other trends that have worked to improve the performance, efficiency, and security of the blockchain system itself, In the Internet of Things, healthcare, supply chain management, the banking sector, and digital marketing In addition to studies that include improving the efficiency, security, and development of the system
