Okay, I need to create a Wikipedia-style document about "Consensus Algorithms" under the categories of Technology → Data Science → Analysis. Let me start by understanding what a consensus algorithm is. From what I remember, it's a process in distributed systems where nodes agree on a single data value. But I should verify that.

First, the structure: H1 for the title, then an overview section. Then sections with H2 and H3. The user wants at least 800 characters, so I need to make sure each section is detailed enough.

For the introduction, I'll explain what consensus algorithms are, their importance in distributed systems, maybe mention some use cases like blockchain or databases. Need to keep it clear and concise.

Next sections: Maybe start with "1. 정의 및 개념" (Definition and Concept). Here, I can define consensus algorithms, their purpose, and key characteristics. Then "2. 주요 유형과 작동 원리" (Main Types and Working Principles) where I'll list different types like Paxos, Raft, PBFT, and maybe mention Proof of Work and Proof of Stake for blockchain. Each type should have a brief explanation.

Then "3. 응용 분야" (Application Areas). Here, I can talk about blockchain, distributed databases, cloud computing, etc. Maybe include examples like Bitcoin or Ethereum using PoW/PoS. Also, mention how they ensure data consistency in distributed systems.

Another section could be "4. 장단점 및 비교" (Advantages and Disadvantages) comparing different algorithms. For example, Paxos is robust but complex, Raft is more understandable, PBFT for permissioned blockchains, etc. Maybe a table here would help.

Then "5. 미래 전망과 발전 방향" (Future Prospects and Development Trends). Discuss ongoing research, maybe new algorithms, improvements in scalability or security. Also mention how they're evolving with technologies like AI or quantum computing.

Need to include references or related documents at the end. Maybe list some books, papers, or websites for further reading.

I should check if I'm using technical terms correctly. For example, "distributed systems" is correct. Make sure explanations are clear even for someone not familiar with the topic. Avoid jargon without explanation.

Wait, the user mentioned to use H2 and H3. So after the introduction (H1), the first section would be H2: 개요/소개. Then under that, maybe H3 sections? Or is the overview a separate H2? Let me structure it properly.

Also, need to ensure each section has enough content. For example, in "주요 유형과 작동 원리", I should explain each algorithm's mechanism briefly. Maybe use bullet points or code blocks if necessary, but since it's about algorithms, maybe just descriptions.

Check for accuracy: Paxos is a consensus protocol used in distributed systems, Raft is designed to be more understandable than Paxos. PBFT (Practical Byzantine Fault Tolerance) is used in blockchain for permissioned networks. Proof of Work and Proof of Stake are consensus mechanisms in cryptocurrencies.

Make sure the document flows logically from definition to types, applications, pros/cons, future trends. Avoid repetition. Keep paragraphs short for readability.

Also, check that all sections meet the 800-character minimum. Let me count: each section should have several paragraphs or bullet points. Maybe around 200-300 characters per section. The introduction could be a bit longer.

Need to use proper markdown formatting: # for H1, ## for H2, ### for H3. Use bold or italics where appropriate but not overdo it. Avoid code blocks unless necessary, maybe in examples if any.

Finally, proofread for clarity and correctness. Ensure that the information is up-to-date and accurate. Maybe mention recent developments if possible.
