Introduction to Blockchain is a 2-credit Skill Enhancement Course (SEC) under Delhi University's UGCF 2022, taught in 2025-26 as a 0 lecture, 0 tutorial, 2 practical (p.1 credit table). As per the official syllabus on academicaffairs.du.ac.in, the course is organised as two 16-hour theory blocks — Unit-1 Blockchain basics, node fundamentals, Ethereum, smart contract and DApp development in Ethereum plus Hyperledger fundamentals (16 hours) and Unit-2 Fabric network setup, chaincode and DApp development (16 hours) — plus a 28-hour capstone project. Capstone project is an assignment/project building a distributed application on Hyperledger Fabric (p.2). Evaluation is 'as per guidelines notified by the University of Delhi' (p.2). Students often describe blockchain generically and lose marks on specifics like how Ethereum transactions are validated by miners, Solidity for smart contracts, or Hyperledger chaincode — all listed as outcomes and asked viva-style. For revision, map each PYQ to its unit — middle units repeat most — and confirm your college's exact paper code before the exam, as SEC codes vary by theme (as of 12 Sept 2026).
