With the increase in the number of Internet of Things (IoT) applications, the reliance on
robust networking, reliable communications, and efficient and secure data storage is …

This paper centers around a simple yet crucial question for everyday users: How should one
choose their delegated validators within proof-of-stake (PoS) protocols, particularly in the …

With rapid development of blockchain technology as well as integration of various
application areas, performance evaluation, performance optimization, and dynamic decision …

Cryptojacking is a new type of Internet of Things (IoT) attack, where an attacker hijacks the
computing power of IoT devices, such as wireless routers, smart TVs, set-top boxes, or …

The proof-of-work (PoW) based blockchains are more secure nowadays since profit-oriented
miners contribute more computing powers in exchange for fair revenues. This virtuous circle …

In this paper, we study how to optimize existing Non-Fungible Token (NFT) incentives. Upon
exploring a large number of NFT-related standards and real-world projects, we come across …

This study analyzes the security implications of Proof-of-Work blockchains with respect to the
stale block rate and the lack of a block verification process. The stale block rate is a crucial …

Selfish mining, one of the most renowned attack in Bitcoin, involves a selfish miner
withholding discovered blocks and broadcasting them at an opportune moment to gain …

In a Proof-of-Work blockchain with multiple selfish miners, can we accurately and efficiently
calculate the reward earned by each miner? The problem is fundamental but difficult to be …

Previous researches have shown that a miner using selfish mining strategy is not
necessarily profitable if the selfish mining rate is not large enough. In such situation, a miner …
