AstroBWT Pseudo CODE

This algorithm is a Proof of Work (PoW) mechanism used in cryptocurrencies or distributed systems to secure and validate transactions or blocks. Here's a breakdown of the steps outlined in the pseudocode:

def AstroBWT(input String): 
    # Input -> SHA256 -> Salsa20 -> anti-FPGA loop -> BWT -> SHA256 = Pow hash
    Step1 = SHA3-256(input)  # Calculate SHA3-256 hash of input data
    Step2 = Salsa20(Step1)  # Expand the data via Salsa20, 69371 bytes
    loop:
        Step3 = anti-FPGA(Step2)  # anti-FPGA loop
    Step4 = BWT(Step3)  # Calculate BWT of step 3
    Step5 = SHA3-256(Step4)  # Calculate final POW hash
    return Step5

AstroBWT Cryptographic Process:

1. Input Data: This represents the initial data set that serves as the starting point for the process.
2. SHA3-256: It's a cryptographic hash function used to produce a fixed-size output (256 bits) called a hash value or digest. The hash is computed based on the input data using the SHA3-256 algorithm, providing a unique representation of the input data.
3. Expand using Salsa20 Cipher: Salsa20 is a stream cipher known for its speed and security. Expanding the data using the Salsa20 cipher involves generating a longer sequence of pseudorandom bits (expanding the initial data) using the cipher's encryption mechanism.
4. Calculate BWT: The Burrows-Wheeler Transform (BWT) is applied to the expanded data. It's a reordering technique used in data compression. The BWT rearranges the symbols within the data, creating a transformed version suitable for improved compression.
5. SHA3-256 of BWT Data: Similar to Step 2, this calculates the SHA3-256 hash of the BWT-transformed data obtained in Step 4. It provides a fixed-size representation of the transformed data for verification or identification purposes.
6. Expand using Salsa20 + Random Number: This step involves additional expansion of the data using the Salsa20 cipher, but with an extra random number. The random number is derived from the SHA3-256 result obtained in Step 4, adding a layer of randomness to the expanded data.
7. Calculate BWT of Step 6: The BWT is recalculated for the further expanded data obtained in Step 6. This process repeats the transformation technique on the newly modified dataset.
8. SHA3-256 of BWT Data from Step 7: Similar to Steps 2 and 5, this calculates the SHA3-256 hash of the BWT-transformed data obtained in Step 7, providing a unique and fixed-size representation of the final transformed data after multiple expansions and BWT calculations.
