This paper details the specification and implementation of a single-machine blockchain simulator. It also includes a brief introduction on the history & underlying concepts of blockchain, with explanations on features such as decentralization, openness, trustlessness, and consensus. The introduction features a brief overview of public interest and current implementations of blockchain before stating potential use cases for blockchain simulation software. The paper then gives a brief literature review of blockchain's role, both as a disruptive technology and a foundational technology. The literature review also addresses the potential and difficulties regarding the use of blockchain in Internet of Things (IoT) networks, and also describes the limitations of blockchain in general regarding computational intensity, storage capacity, and network architecture. Next, the paper gives the specification for a generic blockchain structure, with summaries on the behaviors and purposes of transactions, blocks, nodes, miners, public & private key cryptography, signature validation, and hashing. Finally, the author gives an overview of their specific implementation of the blockchain using C/C++ and OpenSSL. The overview includes a brief description of all the classes and data structures involved in the implementation, including their function and behavior. While the implementation meets the requirements set forward in the specification, the results are more qualitative and intuitive, as time constraints did not allow for quantitative measurements of the network simulation. The paper concludes by discussing potential applications for the simulator, and the possibility for future hardware implementations of blockchain.

Cryptopoly: Using Ethereum State Channels for Decentralized Game Applications

Description

All modern multiplayer games are administered by having players connect to a remote server which is used to provide the ground truth for game state and player actions. This use

All modern multiplayer games are administered by having players connect to a remote server which is used to provide the ground truth for game state and player actions. This use of a central server provides a simple and intuitive way to administer game servers but also provides a single point of failure, as each server must be able to process all actions coming in and make a decision on whether the action is allowed or not, and how to update the game state accordingly. In cases where the server is under significant load, either from a very popular game release or from a deliberate attack, the game slows down or completely crashes. When there is a server action backlog, this can allow malicious actors to perform previously impossible actions. By instead using a decentralized platform, we can build a robust system that allows playing games through a P2P manner, filling in the need for central servers with consensus algorithms that provide the security on the part of a central authority. This project aims to show that a decentralized solution can be used to create a transparent, fully playable game of Monopoly with complex features that would be more scalable, reliable, and cost-effective compared to a centralized solution; meaning that games could be produced that costs pennies to publish and modify, taking seconds to propagate changes globally, and most importantly, cost nothing for upkeep. The codebase is available here: https://github.com/SirNeural/monopoly

Mengde Signatures: The First Practical Implementation Of Proxy Digital Signatures

Description

Proxy digital signatures are a subset of proxy cryptography that enable a peer, as a proxy delegator, to delegate signing privileges to another trusted peer, who becomes a proxy signer.

Proxy digital signatures are a subset of proxy cryptography that enable a peer, as a proxy delegator, to delegate signing privileges to another trusted peer, who becomes a proxy signer. The proxy signer then signs authorized transactions routed to it from the proxy delegator, to then send to the intended third party on their behalf. This has great applications for computer networks where certain devices lack sufficient computational power to secure themselves and may rely on trusted and computationally more powerful peers, particularly within edge and fog networks. Although there are multiple proxy digital signature schemas that are circulated within cryptography-centric research papers, a practical software implementation has yet to be created. In this paper we describe Mengde Signatures: the first practical software implementation of proxy digital signatures. We expound upon the current architecture and process for how proxy signatures are implemented and function in a software engineering context. Although applicable to many different types of networks, we showcase the application of Mengde Signatures on an open source Proof-Of-Work Blockchain.

This study aims to examine how the use of consensus-based transactions, smart contracts,and interoperability, provided by blockchain, may benefit the blood plasma industry. Plasmafractionation is the process of separating blood into multiple components to garner benefitsof increased lifespan, specialized allocation, and decreased waste, thereby creating a morecomplex and flexible supply chain. Traditional applications of blockchain are developed onthe basis of decentralization—an infeasible policy for this sector due to stringent governmentregulations, such as HIPAA. However, the trusted nature of the relations in the plasmaindustry’s taxonomy proves private and centralized blockchains as the viable alternative.Implementations of blockchain are widely seen across pharmaceutical supply chains to combatthe falsification of possibly afflictive drugs. This system is more difficult to manage withblood, due to the quick perishable time, tracking/tracing of recycled components, and thenecessity of real-time metrics. Key attributes of private blockchains, such as digital identity,smart contracts, and authorized ledgers, may have the possibility of providing a significantpositive impact on the allocation and management functions of blood banks. Herein, we willidentify the economy and risks of the plasma ecosystem to extrapolate specific applications forthe use of blockchain technology. To understand tangible effects of blockchain, we developeda proof of concept application, aiming to emulate the business logic of modern plasma supplychain ecosystems adopting a blockchain data structure. The application testing simulates thesupply chain via agent-based modeling to analyze the scalability, benefits, and limitations ofblockchain for the plasma fractionation industry.

The objective of this paper is to provide an educational diagnostic into the technology of blockchain and its application for the supply chain. Education on the topic is important to prevent misinformation on the capabilities of blockchain. Blockchain as a new technology can be confusing to grasp given the wide possibilities it can provide. This can convolute the topic by being too broad when defined. Instead, the focus will be maintained on explaining the technical details about how and why this technology works in improving the supply chain. The scope of explanation will not be limited to the solutions, but will also detail current problems. Both public and private blockchain networks will be explained and solutions they provide in supply chains. In addition, other non-blockchain systems will be described that provide important pieces in supply chain operations that blockchain cannot provide. Blockchain when applied to the supply chain provides improved consumer transparency, management of resources, logistics, trade finance, and liquidity.

The purpose of this thesis research project is to explore blockchain technology and its present and future applications within supply chain management. Emerging blockchain technologies, both public and private, are already showing great promise for a number of applications in and outside supply chain management. Our sole focus is to understand the fundamentals of blockchain, smart contracts, current applications in supply chain, and the future possibilities for blockchain to shape global supply chains. Many have theorized about how private blockchains can be implemented and used; however, there is little research to date that has collected and explored the actual use cases in industry today. The mission of this research paper is to separate theory from the current state of the technology and provide a clearer understanding of where the technology is headed in the near future. We aim to produce a work that will provide a comprehensive description and commentary on current use cases for the education of students and industry professionals alike. With any new technological developments, terminology and technicalities can be paralyzing, and this is particularly true for blockchain technology. For this project, our goal was to create a document that cuts through the complexities and allows a non-technical audience to gain a strong foundational understanding of blockchain's potential and current limitations within supply chains. Provided this, some highly technical concepts and implementation details will not be explored due to the complexity and minimal understanding even amongst industry experts. As future supply chain professionals, we are motivated to further our understanding of blockchain technologies and the potential for this technology to shape the future of supply chain management.

Blockchain technology has the potential to be an effective form of identity management and human trafficking prevention as an identity solution. The topic of this thesis originates from the United Nation’s Sustainable Development Goal to create a form of identity for every individual on the plant by the year 2030. This research analyzed and compared primarily global databases with information on human trafficking populations and unidentified populations to understand both issues, and the intersections of their populations. This is followed by a discussion of Blockchain technology’s attributes and a Blockchain identities potential characteristic. This research concludes that a Blockchain based identity can be used to mitigate human trafficking by creating various forms of identity for affected populations. Four basic factors of Blockchain technology can be utilized through public and private partnerships to address different parts of the AMP model for the cycle of human trafficking. The conclusion that Blockchain is a potential solution to the analyzed issues comes with caution and alongside an examination of the risk factors involved in implementing this technology and the future investigation necessary to test this conclusion. Risk factors with using blockchain technology as a solution are examined to help direct future research on the topic. The conclusion is based off Blockchain’s ability to address specific problems in human trafficking and the global identity crisis (GIC) that were found in the analysis.

The purpose of this thesis is to imagine and predict the ways in which humans will utilize technology to feed the world population in the 21st century, in spite of significant challenges we have not faced before. This project will first thoroughly identify and explain the most pressing challenges the future will bring in climate change and population growth; both projected to worsen as time goes on. To guide the prediction of how technology will impact the 21st century, a theoretical framework will be established, based upon the green revolution of the 20th century. The theoretical framework will summarize this important historical event, and analyze current thought concerning the socio-economic impacts of the agricultural technologies introduced during this time. Special attention will be paid to the unequal disbursement of benefits of this green revolution, and particularly how it affected small rural farmers. Analysis of the technologies introduced during the green revolution will be used to predict how 21st century technologies will further shape the agricultural sector. Then, the world’s current food crisis will be compared to the crisis that preceded the green revolution. A “second green revolution” is predicted, and the agricultural/economic impact of these advances is theorized based upon analysis of farming advances in the 20th century.
