As we depend more and more on online platforms, keeping user login secure is a top priority. Traditional methods, which often store usernames and passwords on central servers, are increasingly at risk from cyberattacks like data breaches, phishing scams, and identity theft. To overcome these problems, this project suggests a decentralized login system based on block chain technology. Blockchain provides a secure and transparent record where login information are managed safely without a central authority. Smart contracts enable automated checks that are resistant to tampering and unauthorized access. Unlike standard systems, this approach eliminates the single point of failure by spreading data across a blockchain network, ensuring better uptime and security. Users have more control over their online identities because blockchain-based systems avoid storing cleartext passwords or sensitive information in one location. Integrating blockchain with crypto wallets, like MetaMask, further strengthens user login by enabling secure, key-based identity checks. This method not only boosts user confidence and privacy but also fits with the future of the decentralized web (Web3). This proposed solution shows how blockchain can transform login systems by providing a secure, scalable, and transparent alternative to traditional login processes.

Although the idea of communication between devices is not new, its developmenthas been rapid and significant since it helps people do their jobs more efficiently and keeps them fully informed of events at their homes and workplaces thanks to technology like the Blockchain (BC) based Internet of Things (IoT). However, this new technology suers from security issues and the existing research has not addressed these issues in depth. In this paper, a simulation of the smart network of the firefighting station was made. BC technology was used with one of the consensus algorithms which was proof of authority (PoA) to make this network more secure and private, in addition to the use of a hash function such as secure hash algorithm 384 (SHA-384), which is a one-way encryption function and was used to verify the BC data integrity so that it was dicult to hack the data and thus be the data transmission process is more secure. Also, the Espressif 32 (ESP32) device was chosen for this project because it oers several useful characteristics, including Wi-Fi and the capacity for rapid data transmission. It was observed from the results obtained from the application of consensus algorithms that the firefighting station network was made more secure and the PoA algorithm was better in several aspects such as execution time (maximum 0.4 S) and memory used (maximum 610 KB). Finally, the proposed work that was applied to the firefighting station was good in terms of safety and privacy, as the work of this station became more efficient.

Smart fire detection and insurance systems have gained considerable attention from researchers and industries. At the same time, automatic requests for fire brigade services to cure fire and instant claims settlement to defend insurance fraud are lacking in literatures. We propose a trusted fire brigade service and insurance claim (FLAME) framework using blockchain for enterprises to provide immediate fire brigade services and prevent insurance frauds. A system model is presented to explain architecture, and overall functionality of FLAME using blockchain. Further, a sensing network and connectivity model is proposed to detect true fire and send an emergency service request to monitoring station. Smart contracts are designed to automate fire brigade service and insurance claim processes. A prototype of the FLAME is implemented on hyperledger besu blockchain using Istanbul Byzantine Fault Tolerance 2.0 consensus protocol. Simulation results show that latency and throughput of the FLAME are better compared to state-of-the-art models.

Global warming caused by air pollution and ecosystem changes are very important. Pollutants such as harmful gases and fine dust generated in industrial sites are the main causes of air pollution. Strict control of emissions of air pollutants from industrial sites is required. In this paper, we propose a real-time air pollution index measurement platform using 5G wireless network and blockchain. The proposed platform breaks the existing passive method and collects data in real time through IoT sensor based on 5G wireless network. In order to prevent forgery and tampering of collected data, we use blockchain technology to encrypt and transmit to cloud and provide real-time air pollution index measurement platform. You can extract technology-intensive data through edge computing and cloud computing. This paper describes the architecture of the proposed platform and introduces use cases.

This paper discuss the smoke sensor and the relay control in the smart home.STM32 is used as the central part of the whole system and LwIP protocol is also applied to transfer data. The system uses the MQ-2 smoke sensor detect the concentration of combustible gases in air, and uses the SRD-05VDC-SL-C to close and cut off the circuit. The paper also discuss the sensitivity characteristics and the temperature and humidity effect of the smoke sensor. At the end of the paper, it is given the C code in the KEIL MDK environment.
