base58 decode 1FwZXt6EpRT7Fkndzv6K4b4DFoT4trbMrV to sha256

To decode a Base58 string and then hash it with SHA-256, you would follow these steps:

1. **Base58 Decode**: Convert the Base58 string into a byte array.
2. **SHA-256 Hashing**: Take the resulting byte array and generate its SHA-256 hash.

Let me do this for you:

1. **Base58 Decode**: The provided Base58 string is `1FwZXt6EpRT7Fkndzv6K4b4DFoT4trbMrV`. When decoded from Base58, it results in a byte array.

2. **SHA-256 Hash**: Once you have the byte array, you apply the SHA-256 hashing algorithm to obtain the hash.

### Here is a Python example to accomplish this:

```python
import hashlib
import base58

# Base58 string
base58_string = '1FwZXt6EpRT7Fkndzv6K4b4DFoT4trbMrV'

# Step 1: Decode from Base58
decoded_bytes = base58.b58decode(base58_string)

# Step 2: SHA-256 hashing
sha256_hash = hashlib.sha256(decoded_bytes).hexdigest()

print(sha256_hash)
```

### Note:
Make sure to have the `base58` library installed in your Python environment. You can install it using pip:

```bash
pip install base58
```

### Running the Code
When you run the above code, it will give you the SHA-256 hash of the decoded byte array from the Base58 string `1FwZXt6EpRT7Fkndzv6K4b4DFoT4trbMrV`. 

You can also perform these same steps using various programming languages or tools that support Base58 decoding and SHA-256 hashing. If you'd like, I can help you with examples in different languages!
