Capstone on the Blockchain Trilemma
The capstone investigates the blockchain trilemma by assessing various types and levels of permissioning to determine the appropriate tools—such as modularity thesis, consensus mechanisms, dynamic sharding, zero-knowledge proofs, smart contracts, and security standards—that can effectively balance decentralization, scalability, and security. Through this analysis, the paper seeks to provide a framework for optimizing blockchain architecture in real-world applications.
Blockchain Payment System
This paper outlines the design of a scalable blockchain-based payment system with off-chain storage. It details the system’s architecture, including microservices, consensus mechanisms, and security, emphasizing efficiency and data integrity. The deployment on Azure ensures scalability and reliability while maintaining compliance with PCI-DSS. The system is optimized for secure transactions, with off-chain storage handling large or sensitive data to reduce blockchain load.

Blockchain Decision Flow Chart
A flow chart was developed to guide organizations in deciding the need for blockchain architecture and the appropriate type. It starts by evaluating the requirement for peer-to-peer digital relationships or specific challenges. Then it assesses the need for a system of records, token creation, and the involvement of multiple writers. Depending on the responses, the chart leads to the most suitable blockchain type—public, private, consortium, or hybrid—by considering factors like permissioning, scalability, privacy, and centralization. This tool ensures that the chosen blockchain architecture aligns with the organization's strategic and operational goals.
Proposal for Anti-Doping Blockchain System
This document proposes a hybrid blockchain system to improve trust and transparency in global anti-doping efforts by WADA, IOC, and NADOs. Using Hyperledger Fabric for secure data management and Ethereum for public transparency, the solution aims to create a tamper-resistant, decentralized record of athlete testing. By enhancing traceability and accountability, the system addresses existing ethical and operational challenges, with governance and security best practices ensuring compliance and effectiveness in promoting fair sports.
