“…Thus, it is natural that there are many LE and lottery schemes using smart contracts. To the best of our knowledge, all existing blockchain-based lottery schemes [13]- [15], [17], [17] use RNG, either through (i) pseudo-random number generators or random oracles that use blockchain states as seeds, or (ii) an external decentralized random number generation protocol. Therefore, they all inherit the limitations of existing decentralized random number generation methods.…”

Leader Election (LE) is an important process in distributed systems and blockchain technology, where one of the participants is designated as the leader or coordinator. LE is a part of many distributed systems and blockchain protocols, smart contract applications, and lotteries. Traditional randomized LE methods usually involve distributed random number generation (RNG) to select the leader. These approaches can be vulnerable to manipulation, fail to ensure fairness, or require inefficient and costly procedures, e.g., verifiable delay functions (VDFs) and publicly-verifiable secret sharing (PVSS). This Bachelor's thesis in Informatics introduces a new approach to randomized LE. The key insight is that fair leader election can be achieved without relying on explicit decentralized RNG. This is based on the game-theoretic assumption that every participant prefers to be chosen as the leader and would avoid actions that decrease their chances. This game-theoretic incentive can simplify LE protocols compared to RNG. PureLottery, inspired by single-elimination knockout tournaments in sports, offers a fair, bias-resistant, and practical solution for LE in blockchain environments. The underlying principle is that only two participants play against each other in each match, making collaboration efforts to manipulate the result useless.PureLottery is also efficient with its computational resources and communication complexity, making it practical for implementation as a smart contract. The protocol provides strong game-theoretic guarantees, incentivizing honest behavior, and is robust against adversaries, ensuring that dishonest behavior does not increase their chances of election. PureLottery is designed to be highly resistant to bias, ensuring that each honest player has a minimum winning probability of at least 1/n, regardless of any potential manipulation by an adversary overseeing the remaining n − 1 participants. This means that engaging in dishonest practices does not boost an adversary's likelihood of success, even if they have influence over all participants except one.Problems similar to the leader election problem can be solved with a modified PureLottery protocol. These problems include a ranking of all participants, electing multiple leaders simultaneously, and leader aversion. The PureLottery protocol has multiple applications in different fields. It can be easily implemented in smart contract applications like lotteries. Moreover, it can be utilized in blockchain and distributed systems protocols. An open-source implementation of PureLottery is provided, dedicated to the public domain.

“…The contributions of this study can be used as a reference to design the library channel integration strategy. Finally, Jo et al (2019) presented a trusted security zone architecture that adopted a blockchain technology to offer the secure sharing of data. The empirical results would be very useful for the public library and the future smart library.…”

“…Examples of permissionless networks, such as Bitcoin and Ethereum, let anybody join, access the ledger, and contribute to the consensus mechanism. Public blockchains are decentralized and secure frameworks that provide transparency and trustworthiness, making them suitable for various applications [7].

Ensuring safe and transparent tracking of nuclear materials in the modern era is critical for global security and compliance with international regulations. Blockchain technology, a decentralized and immutable ledger, offers a new approach to recording transactions, increasing trust without intermediaries. In this study, it was investigated whether nuclear material tracking was performed with advanced technology blockchain from past to present; it was seen that there needed to be a study on this subject in the literature, and that there was a gap. Search results proving this are presented. The authors present a model that can enable nuclear material tracking with blockchain technology, which will create a solid structure for recording and verifying every process step in the nuclear supply chain, from the creation of the first product to destruction. This model discusses how nuclear materials, which are very important to track from the beginning until they become waste, can be tracked with blockchain technology, and the contributions they can make nationally and internationally are explained. As a result of the research, it is shown that blockchain technology has the potential to pave the way for more resilient and precise nuclear supply chains by significantly increasing the security and efficiency of nuclear material tracking.
