Cryptographic Principles in Blockchain – Assignment Report

This report looks at twelve cryptographic terms that blockchain depends on. For each one, it gives a short definition, explains what the term does in blockchain or cryptography, and shows an example of where it is used. The terms are sorted into four groups: hash functions, keys and signatures, data integrity, and consensus and attacks. Taken together, they explain how a blockchain keeps its records safe, shows who sent a transaction, notices changes, and stops the same money from being spent twice. Keywords: hash function, deterministic property, collision resistance, public key cryptography, private key, digital signature, Merkle tree, immutability, proof-of-work, tamper detection, 51% attack, double spending

Blockchain Fundamentals – Assignment

This report explains the fundamentals of blockchain technology. It describes the four key components of a blockchain (blocks, chain, nodes, and decentralization) and how they work together to keep records secure and tamper-resistant. It then compares public, private, and consortium blockchains, giving one benefit and one limitation of each. Finally, it presents two real-world applications: Bakong, Cambodia's national payment system, in finance, and IBM Food Trust in supply chain traceability. The report concludes that blockchain offers a transparent and secure way to share records, and that the right type depends on an organization's needs.

Blockchain Technology: History, Fundamentals, and Applications

Blockchain is a technology that allows information to be recorded and shared across multiple computers without depending entirely on one central authority. It first became widely known through Bitcoin in 2009 and has since developed into a technology with applications beyond cryptocurrency. This paper explores the history of blockchain, explains how it works, and introduces its main components and different types. It also discusses how blockchain can be used in industries such as finance, healthcare, supply chain management, and education. In addition, the paper examines its benefits and challenges, including security, transparency, privacy, and scalability. Overall, blockchain has the potential to improve how information is managed and verified, but its usefulness depends on the needs of each industry and how the technology is applied.
