Voting has become one of the methods used by humans to determine decisions in a matter. As technology has developed, conventional Voting has also followed the transformation in the adaptation of today's digital age. There is an electronic version of this Voting, often referred to as e-voting (electronic Voting). Of course, the application of technology in Voting will lead to public opinion about concerns about maintaining network privacy and security in e-voting. Security problems can be overcome with technology that is currently being maximally utilized in various fields of life, namely blockchain technology. In improving the security of e-voting, Blockchain is used in P2P networks. Implementing the blockchain system in e-voting will result in a secure e-voting system to reduce the percentage of vote forgery in the e-voting system. Implementing a blockchain-based e-voting system will involve cryptography, software engineering theory, and voting theory. In realizing blockchain-based e-voting, several stages are required. (1) Counterfeit votes avoid adjusting the voting record model based on ledger technology, (2) in terms of authentication. The technology complemented by designing a user model based on Elliptic Curve Cryptography (ECC), (3) providing a model designed for voters to change their votes before the time limit specified. The implementation of Blockchain in this e-voting system is transparent with the existence of a blockchain system that provides notifications to all nodes to approve an incoming vote data. With this transparency, it can reduce fraud and the election of leaders according to people's choices.

Abstract— The technique of following a product or a batch of things throughout the supply chain to ensure that the products that reach clients are authentic and tamper-proof is known as asset tracking. The ultimate goal of an asset monitoring system is to track products along the supply chain, verifying that they haven't been tampered with and, if they have, pinpointing where the tampering took place. Traditional tracking technologies, such as BLE (Bluetooth Low Energy Beacon), which works within a limited range, RFID, and above-mentioned systems, are expensive and centralised. So, for this project, we'll use Blockchain Technology, which is an immutable, tamper-proof, decentralised distributed ledger with security features that allows us to establish an asset tracker that can follow our product along the supply chain. Ethereum is used to implement the system. Unlike other methods, there are no hardware components or large gadgets that may be removed from the original object and attached to the copy. Keywords— Blockchain, Supply Chain, Smart Contract, Keccak-256, Ethereum,GUI

The healthcare industry is one of the top priorities for every country, as the government wants to improve the process and provide better services to the public in the health sector. In COVID19, there is a need to immediate response and secured way of storing data due to overwhelming patients admitting to the hospitals. Many stakeholders are involved in the health sector, such as patients, doctors, pharmaceutical companies, laboratories, and hospitals which makes the complete system complex. Security and privacy are the major concern of comprehensive patient-related information accessed by the involved participants. Blockchain technology is capable of ensuring data integrity and privacy with immutable features. The blockchain technology can be implemented in public and private means, but the medical data is sensitive information which cannot be shared to the public. In this paper, the permissioned blockchain is implemented for healthcare sector using Hyperledger Fabric. The Fabric is an open-source platform through which a Smart Contract is developed on the blockchain network. With the help of a smart contract, the secure transaction is performed on the ledger to store the confidential data related to a patient. The data stored in the form of an immutable block ensures the security of health records stored on distributed ledger through a smart contract. With this implementation, the efficient healthcare process is simplified and the transactions with multiple end-users are done securely, leading to transparency and traceability.
The use of digital currency or cryptocurrency in various virtual transactions is common due to its easiness. Cryptocurrency is a digital currency that is used for virtual transactions on the internet network. The most common types of cryptocurrencies include Litecoin, Ethereum, Monero, Ripple, and Bitcoin. Even though cryptocurrencies have secret codes that are quite complicated and complex that serve to protect and maintain the security of digital currencies, it is possible to be hacked by skilled hackers. Cryptocurrency-related hacking is a type of digital crime that is very harmful or dangerous acts. For example, in recent years, cases of hacking on bitcoin transactions using ransomware have been on the rise. Ransomware is malicious software that secretly infects a victim’s device, and suddenly asks for a ransom to decrypt encrypted data. This type of malware aims to blackmail a victim whose computer is infected with ransomware by asking for a certain amount of money as a ransom. Therefore, a design was built in the form of a ransomware detection system based on available bitcoin heist data so as to minimize hacking attacks against cryptocurrency in the future. The ransomware detection system was built using the backpropagation artificial neural network method using Weka software. The best results in data testing are using the parameter number of hidden layer with 9 neurons; learning rate 0.1; and the number of iterations of 5000 yields an accuracy rate of 97%.
