Multihash is a three-element format that represents a hash. It is also known as Type-Length-Value (TLV) format. The format comprises the code for the hashing method, its length, and the hash itself. For example, the code 18 corresponds to SHA2-256, which has a length of 256 bits. The hash value represents the generated hash digest.
Key Points:
- Multihash is a format that represents a hash in a three-element structure.
- It uses Type-Length-Value (TLV) format to include the code, length, and hash.
- The code represents the hashing method, such as SHA2-256.
- The length indicates the number of bits in the hash.
- The hash value represents the generated hash digest.
Frequently Asked Questions:
What is TLV format?
TLV format stands for Type-Length-Value. It is a structure used to encode data, where the type field specifies the type of data, the length field indicates the size of the data, and the value field contains the actual data.
How is Multihash used?
Multihash is commonly used in blockchain technology, cryptocurrency, and decentralized systems to ensure data integrity and verification. It allows different hashing algorithms to be used for different purposes while maintaining a standardized format.
Can Multihash be reversed to retrieve the original data?
No, Multihash is a one-way function. It generates a hash digest that cannot be reversed to retrieve the original data. Its purpose is to provide data integrity and verification.
In Conclusion
Multihash is a format that represents a hash in a three-element structure. It uses Type-Length-Value (TLV) format to include the code, length, and hash. It is commonly used in blockchain technology and decentralized systems to ensure data integrity and verification.
