Description: What Does Grøstlcoin Do?
The Grøstlcoin project aims to develop efficient implementations of the Grøstl hash function across various platforms. The whitepaper details the project's objectives, which include demonstrating the implementation flexibility of the Grøstl algorithm and inspiring further optimizations and ports to other platforms. The primary goal is to provide secure and efficient hashing capabilities for developers.
To achieve these objectives, the Grøstlcoin project employs various software implementation techniques suitable for different platforms, such as 8-bit microcontrollers and modern desktop processors using 256-bit AVX instructions. The whitepaper extensively discusses the Grøstl hash function's design, including its wide pipe construction and AES-like round transformations.
Problem: Why Grøstlcoin Is Being Developed?
The Grøstlcoin project addresses the need for a highly efficient and secure hash function that can be implemented on a wide variety of platforms. The Grøstl hash function, as a finalist in the SHA-3 competition, offers significant security and performance benefits, which are crucial for applications requiring robust cryptographic hashing.
Existing solutions either lack the flexibility to be efficiently implemented across different platforms or do not provide the same level of security and performance as the Grøstl hash function. The limitations of current hashing algorithms in terms of platform-specific optimizations and security margins necessitate the development of a more versatile and secure solution like Grøstlcoin.
Use Cases
- Cryptographic Hashing: Efficient and secure hashing for data integrity and authentication.
- Blockchain: Secure hashing for transaction verification and block creation.
- Password Hashing: Secure storage and verification of passwords.
How Does Grøstlcoin Work?
The Grøstlcoin project consists of the Grøstl hash function, which is designed with a wide pipe construction and AES-like round transformations. The hash function iterates an underlying compression function, where the size of the state passed from one iteration to the next is at least twice as large as the final hash value.
Steps involved in Grøstlcoin operation:
- Input Message: The input message is padded and split into blocks.
- Initial Value: An initial value is defined.
- Compression Function: The compression function processes the message blocks using two permutations (P and Q).
- Output Transformation: After processing all message blocks, an output transformation is applied to produce the final hash value.
Technical Details
The Grøstl hash function operates on the principles of the Merkle-Damgård construction, utilizing a wide pipe design. It employs two permutations, P and Q, which are based on round transformations similar to those of the AES. The hash function supports different output sizes, such as Grøstl-256 and Grøstl-512.

- Wide Pipe Design: Ensures a larger state size for enhanced security.
- AES-like Round Transformations: Utilizes AddRoundConstant, SubBytes, ShiftBytes, and MixBytes transformations.
- Efficient Implementations: Techniques like SIMD and byte slicing for optimized performance.
