Okay, I need to create a Wikipedia-style document about 3DES under the categories of Technology, Cryptocurrency, and Digital Assets. Let me start by understanding what 3DES is. From what I remember, 3DES stands for Triple Data Encryption Algorithm. It's an encryption method that applies the DES algorithm three times with different keys. But wait, since it's in the context of cryptocurrency and digital assets, maybe there are specific applications or relevance here?

First, the structure: H1 title, then an overview section. Then sections with H2 and H3 headings. I need to make sure each part is detailed enough. Let me check if 3DES is actually used in cryptocurrencies. I think Bitcoin uses SHA-256, but maybe some older systems or specific protocols use 3DES? Or perhaps it's more about the general concept of encryption in digital assets.

I should start with an introduction explaining what 3DES is, its origin, and why it's important. Then break down into sections like Technical Overview, Applications in Cryptocurrency, Security Considerations, etc. Maybe also a section on how it compares to other algorithms like AES.

Wait, the user mentioned "디지털 자산" (digital assets), so maybe I should discuss how encryption methods like 3DES are used to secure digital assets. But I need to be accurate here. Is 3DES still commonly used in modern crypto systems? Probably not, since it's considered outdated compared to AES. However, there might be legacy systems or specific use cases.

I need to ensure the information is accurate. Let me recall: DES was a symmetric encryption algorithm, but it became vulnerable to brute-force attacks. 3DES was introduced as an enhancement by applying DES three times with different keys. It's more secure than single DES but slower and less efficient than AES. In cryptocurrency, maybe some older wallets or protocols use 3DES for certain purposes, but I should verify that.

Also, the user wants technical details, so including how 3DES works (e.g., encryption-decryption-encryption process), key sizes, modes of operation like ECB or CBC. Maybe mention that 3DES uses three 56-bit keys, making it effectively 168 bits, but due to meet-in-the-middle attacks, the effective security is around 112 bits.

In terms of structure, after the introduction, I can have sections on Technical Details, Applications in Digital Assets, Security and Limitations, and maybe a comparison with other algorithms. Also, include references or further reading if possible.

I need to avoid any markdown formatting except for the specified headings and lists. Make sure each section is clear and concise. Use technical terms but explain them when necessary. For example, "symmetric encryption" should be explained briefly.

Check for length: at least 800 characters. The current draft seems okay, but I need to expand sections where needed. Maybe add a subsection on how 3DES is implemented in practice or examples of its use in digital assets.

Also, ensure that the document flows logically from introduction to technical details, applications, security aspects, and conclusion. Avoid redundancy. Make sure all information is accurate and up-to-date. Since 3DES is an older algorithm, highlight its relevance today and why it's still mentioned in certain contexts.
