Where to start writing VKR on topic «Comparison of Proof-of-Work and Proof-of-Stake blockchain consensus mechanisms»?

Comparing blockchain consensus mechanisms is a highly relevant topic for students of specialty 09.03.02 «Information Systems and Technologies» at Sinergia University. Such works demonstrate competencies in distributed systems, cryptography, performance analysis, and evaluation of security models.

According to our experience, key challenges arise when selecting metrics for comparative analysis, setting up test environments (testnets), and substantiating the economic efficiency of switching mechanisms. In this guide, you will find a detailed plan, examples for analyzing a fintech company «CryptoTech LLC», ready templates, and labor intensity estimation — from 150 to 200 hours of productive work.

For additional information on formatting standards, see the article «VKR Formatting according to GOST».

How to properly approve the topic and avoid rejections

Topic approval with the scientific supervisor is a critical stage for blockchain-related projects. For comparing PoW and PoS, it is necessary to prepare:

• Relevance Argumentation: energy consumption issues of PoW, centralization risks in PoS, scalability demands;
• Functional Detailization: specify which blockchains are compared (e.g., Bitcoin vs. Ethereum 2.0, or private networks);
• Integration Analysis: study APIs of blockchain nodes, monitoring tools, and simulation environments.

Common Mistakes: vague formulation without specific comparison criteria or lack of security requirements analysis.

Example Discussion with Supervisor:
Student: «I plan to create a comparative model for PoW and PoS focusing on transaction throughput and energy efficiency for a fintech project».
Supervisor: «Accepted, but add words about trust models in the topic and provide a module for security risk assessment».

Standard VKR Structure in Sinergia for Specialty Information Systems and Technologies: Step-by-Step Breakdown

Introduction

Volume: 3-5 pages

Section Goal: Substantiate the need for comparative analysis, define goal, objectives, object, subject, and methodology.

Step-by-Step Instruction:

1. Describe the current situation: debate over blockchain sustainability, security vs. efficiency trade-offs.
2. Formulate the Goal: «Compare Proof-of-Work and Proof-of-Stake blockchain consensus mechanisms in terms of trust, efficiency, and scalability to optimize network selection for CryptoTech LLC».
3. Define Objectives: research consensus algorithms, select metrics, build comparison model, conduct experiments, evaluate efficiency.
4. Specify Object (blockchain consensus processes) and Subject (methods and tools for comparing consensus mechanisms).
5. List Methods: literature review, experimental modeling, statistical analysis, comparative assessment.

Concrete Example for Topic:
Relevance: «Over 2000 blockchain networks exist. Choosing the wrong consensus mechanism leads to 40% higher operational costs and potential security vulnerabilities for fintech projects».

Typical Challenges and Time Costs:

• Error 1: Goal formulated as «compare algorithms» without measurable outcome indicators.
• Error 2: No quantitative assessment of the problem (energy cost, TPS, attack resistance).
• Estimated Time: 15-20 hours.

Chapter 1. Analytical Review of Subject Area and Existing Solutions

1.1. Characteristics of Automation Object: CryptoTech LLC

Section Goal: Describe the company's activities, blockchain usage processes, and substantiate the need for mechanism selection.

Step-by-Step Instruction:

1. Present organizational structure: CTO, blockchain developers, security analysts, users.
2. Describe current process: selecting blockchain platform based on marketing trends rather than technical metrics.
3. Identify problem areas: high transaction fees, slow confirmation times, uncertainty about security guarantees.
4. Formulate requirements: transaction throughput ≥ 1000 TPS, energy consumption reduction ≥ 50%.

Concrete Example:
Table 1. Comparison of Current vs. Target State:

1.2. Review of Consensus Mechanisms and Blockchain Platforms

Section Goal: Conduct comparative analysis of PoW, PoS, and hybrid models.

Step-by-Step Instruction:

1. Classify mechanisms: PoW (Bitcoin), PoS (Ethereum 2.0, Cardano), DPoS, PBFT.
2. Compare by parameters: security assumptions, energy efficiency, scalability, decentralization level.
3. Substantiate choice: PoS offers better efficiency for enterprise use cases.

Concrete Example:
«For CryptoTech LLC, three options were considered: PoW (high security, low efficiency), PoS (balanced), Private Consortium (high efficiency, low decentralization). PoS was chosen for public-facing applications due to optimal balance».

Typical Challenges and Time Costs:

• Error 1: Superficial analysis without calculating Total Cost of Ownership (TCO).
• Error 2: Ignoring security trade-offs (e.g., Nothing-at-Stake problem).
• Estimated Time: 30-40 hours.

It is recommended to use comparison matrices and security threat models for clarity.

Chapter 2. Design and Development of Comparison Model

2.1. System Requirements

Section Goal: Formulate functional and non-functional requirements according to GOST 34.602-89.

Step-by-Step Instruction:

1. Describe functional requirements: data collection from nodes, metric calculation, visualization, reporting.
2. Specify non-functional requirements: response time ≤ 2 sec, support for multiple chains, data accuracy ≥ 99%.
3. Present requirements as a table or Use Case diagram.

2.2. Architecture and Software Implementation

Section Goal: Develop application architecture using UML and implement key components.

Step-by-Step Instruction:

1. Design ER-diagram: entities Blockchain, Node, Transaction, Metric, ComparisonResult.
2. Develop deployment diagram: data collectors, analysis engine, database, dashboard.
3. Describe tech stack: Python for analysis, PostgreSQL for storage, React for dashboard, Docker for deployment.

Concrete Example:
Code snippet for metric calculation:

class ConsensusComparator:
    def __init__(self, pow_chain, pos_chain):
        self.pow = pow_chain
        self.pos = pos_chain
    def calculate_energy_efficiency(self):
        pow_energy = self.pow.get_energy_per_tx()
        pos_energy = self.pos.get_energy_per_tx()
        savings = ((pow_energy - pos_energy) / pow_energy) * 100
        return {
            'pow_consumption': pow_energy,
            'pos_consumption': pos_energy,
            'efficiency_gain_percent': round(savings, 2)
        }
    def calculate_throughput(self):
        pow_tps = self.pow.get_transactions_per_second()
        pos_tps = self.pos.get_transactions_per_second()
        return {
            'pow_tps': pow_tps,
            'pos_tps': pos_tps,
            'scalability_ratio': round(pos_tps / pow_tps, 2) if pow_tps > 0 else 0
        }
    def generate_report(self):
        energy = self.calculate_energy_efficiency()
        throughput = self.calculate_throughput()
        return {
            'summary': 'PoS shows significant improvements in efficiency',
            'metrics': {**energy, **throughput}
        }

Typical Challenges and Time Costs:

• Error 1: Lack of data validation from blockchain nodes.
• Error 2: Ignoring network latency in scalability measurements.
