Proof of Stake (PoS) has been talked about extensively as an alternative way of reaching consensus in blockchain systems. However, there are few publications on how PoS can be used to create new blocks in detail. The undisputed lead proponent for PoS is Ethereum. However, virtually all discussions regarding PoS for Ethereum are centered on selecting a block using PoS after one or more candidate blocks have already been somehow created. PeerCoin was the first blockchain system that incorporated PoS in block creation. Unfortunately, there is no known documentation on how PoS works in PeerCoin. In this paper, we fill this gap by presenting a detailed explanation of the PeerCoin PoS algorithm based on PeerCoin source code. We also dispel the misconception that PeerCoin PoS is based on Proof of Work (PoW) and hence would consume a lot of energy just like proof of work (PoW). In fact, it resembles PoW only on surface and differs from PoW substantially in terms of how to meet the difficulty target.

Payment channel networks, such as Bitcoin's Lightning Network, promise to improve the scalability of blockchain systems.by processing the majority of transactions off-chain. Due to the design, the positioning of nodes in the network topology is a highly influential factor regarding the experienced performance, costs, and fee revenue of network participants. As a consequence, today's Lightning Network is built around a small number of highly-connected hubs. Recent literature shows the centralizing tendencies to be incentive-compatible and at the same time detrimental to security and privacy. The choice of attachment strategies therefore becomes a crucial factor for the future of such systems. In this paper, we provide an empirical study on the (local and global) impact of various attachment strategies for payment channel networks. To this end, we introduce candidate strategies from the field of graph theory and analyze them with respect to their computational complexity as well as their repercussions for end users and service providers. Moreover, we evaluate their long-term impact on the network topology.

HTTP is the backbone of modern web communication. With the rapid growth of web architecture and web communication, it has led to the need for a development of new versions of the HTTP protocol to address performance, security, and communication issues that currently exist. HTTP/3 is a new protocol proposed in 2022 and recently accepted. This paper aims to examine its integration with the QUIC protocol, a UDP-based alternative to traditional TCP-based HTTP versions. HTTP/3 addresses several limitations of previous versions, such as head-of-line blocking, by using QUIC and UDP for traffic communication. This helps HTTP/3 to provide a more responsive and fault-tolerant connection. Despite its benefits, HTTP/3 faces several challenges, including application support for UDP traffic and a potential susceptibility to distributed Denial of Service (DDoS) attacks. Often in literature however, HTTP/3 and QUIC are conflated as the same thing due to their novel nature. Through a systematic literature review, this study seeks to answer three key research questions. First, how does HTTP/3 integrate the QUIC protocol, and what are the key differences between HTTP/3 and traditional TCP-based HTTP versions? Second, which specific features and enhancements in HTTP/3 address the performance and security issues found in previous HTTP versions? The final question is, “How has HTTP/3 been deployed to solve challenges in cloud, IoT, and web environments and what opportunities does it afford? By addressing these questions, this paper will provide a clearer understanding of HTTP/3's architecture, its relationship with QUIC, and its implications for web, IoT, and cloud system architecture.
