These academic documents outline the Blockchain Security curriculum at Sanjivani University, focusing on the technical foundations of distributed consensus. The materials compare primary mechanisms like Proof of Work, Proof of Stake, and Practical Byzantine Fault Tolerance, highlighting how each balances energy efficiency, speed, and decentralization. A significant portion of the text explores network vulnerabilities, such as Sybil attacks, and smart contract risks like reentrancy bugs and integer overflows. Within the Ethereum ecosystem, the sources explain the importance of gas optimization to manage computational costs effectively. Additionally, Decentralized Autonomous Organizations and the GHOST protocol are examined as modern solutions for governance and chain security. Finally, the sources provide real-world context by detailing how permissioned networks using PBFT support Indian infrastructure, including banking consortiums and e-governance land registries.
