RTU Artificial Intelligence Fundamentals of Blockchain 2025 Paper Review

Preparing for the Rajasthan Technical University B.Tech Fundamentals of Blockchain exam requires a strict understanding of distributed systems, cryptographic hashing, and immutable ledgers. For Artificial Intelligence students, blockchain technology provides the structural foundation for secure, decentralized data sharing and federated learning. You cannot build a trustless AI ecosystem or verify the provenance of training data without understanding how distributed consensus prevents tampering. The 2025 paper tests your capability to diagram Bitcoin block structures, explain the double-spend problem, and trace the execution of Ethereum smart contracts. Reviewing this specific branch paper shows you exactly how examiners frame the mathematical and architectural problems across the theoretical modules. This systematic preparation helps you approach your fifth-semester exam confidently.

Understanding the AI Branch Exam Pattern

The RTU theory examination is a three-hour paper worth 70 marks. The paper features three distinct sections designed to evaluate both basic definitions and comprehensive network architecture.

• Part A: This section contains ten compulsory questions worth two marks each. You must define public-key cryptography, state the difference between a public and private blockchain, or explain the concept of Gas in Ethereum under 30 words.
• Part B: You will find seven questions here. You must answer five of them. Each question is worth four marks. Your answers require explaining the Byzantine Generals' computing problem, drawing the structure of a Merkle tree, or outlining the technology stack of a blockchain protocol.
• Part C: This section offers five major questions. You need to answer three. Each question carries ten marks. These require you to execute a detailed comparison of the Bitcoin and Ethereum consensus models, write the logic flow for a decentralized application (DApp) using smart contracts, or analyze the tiers of blockchain technology (1.0, 2.0, and 3.0).

Core Topics Evaluated in the AI Paper

The 2025 question paper covers several critical modules that establish the rules for decentralized networks. Focus your study time on these specific areas to maximize your score.

Cryptography and Distributed Basics

This module evaluates your understanding of the foundational security layer. You must master the mechanics of the Double-Spend Problem and how distributed consensus solves it. Study the role of Hashing (specifically SHA-256) and Public-Key Cryptography in securing transactions. The paper frequently features questions asking you to explain how distributed systems achieve fault tolerance through solutions to the Byzantine Generals' Problem.

Bitcoin Protocol and Architecture

The original cryptocurrency sets the structural baseline. You must understand the exact block structure, including the block header, timestamp, nonce, and transaction list. Practice explaining the operational features of the Bitcoin network, specifically its Proof-of-Work (PoW) consensus model. You must also be prepared to write about the incentive model that rewards miners for securing the ledger.

Ethereum and Smart Contracts

This module shifts focus to programmable blockchains. You must master the concept of Smart Contracts, which allow self-executing code to run on the blockchain. Study the Ethereum structure and its specific operations, focusing on the Ethereum Virtual Machine (EVM). Practice comparing the Ethereum consensus and incentive models directly against Bitcoin's architecture.

Tiers and Types of Blockchain Technology

This theoretical module categorizes the evolution and deployment of distributed ledgers. You must be able to define and differentiate between Blockchain 1.0 (currency), Blockchain 2.0 (smart contracts), and Blockchain 3.0 (DApps and scaling). Expect ten-mark questions asking you to compare the structural permissions and use cases of Public Blockchains, Private Blockchains, Semi-Private Blockchains, and Sidechains.

Answer Writing Strategy for High Marks

RTU evaluators look for clean architectural block diagrams, explicitly stated cryptographic steps, and clear comparative tables. Use a blue pen for your general text and explanations, and use a black pen and ruler for drawing block headers, hash pointers, and network topologies.

In Part A, answer directly. If a question asks for the definition of a smart contract, state clearly that it is a self-executing contract with the terms of the agreement directly written into lines of code deployed on a blockchain network.

In Part B, use clear illustrations. When explaining how blocks are linked, do not just write a paragraph. Draw two consecutive blocks, showing explicitly how the previous block's hash is stored in the current block's header to form an immutable chain.

In Part C, precision in comparison is critical. When solving a ten-mark question on blockchain tiers, use a structured format with distinct headings for Blockchain 1.0, 2.0, and 3.0. Give real-world examples for each tier (e.g., Bitcoin for 1.0, Ethereum for 2.0). When comparing public and private blockchains, construct a clear table contrasting them on access control, speed, consensus mechanisms, and anonymity. Draw a clean box around your final structural diagrams.

Time Management During the Exam

Allocate 20 minutes to Part A. Spend 40 minutes on Part B. Reserve the remaining 120 minutes for the three long-answer questions in Part C. Drawing multi-block structures, writing out smart contract logic flows, and structuring detailed comparative tables requires steady focus and significant time. This plan guarantees you 40 minutes per major question, giving you time to cross-verify that your hash pointers are drawn in the correct direction. Use the final 10 minutes to verify your question numbering, ensure all diagram components are labeled correctly, and check that you have not skipped any intermediate steps in your consensus model explanations.
