Binary Visualizer

Visualizing the decoding process for an STObject blob, such as a transaction, ledger object, or manifest in the XRP Ledger involves parsing the binary data into a human-readable format. This process is essentially the reverse of serialization. Here's a step-by-step breakdown of how you might visualize the decoding process:

1. Input Binary Data: Start with the binary blob that represents the STObject. This is typically a hexadecimal string.

2. Identify Field IDs: The binary blob is composed of a sequence of fields. Each field starts with a Field ID, which is a combination of a type code and a field code. The Field ID determines the kind of data that follows and how to interpret it.

3. Parse Each Field: For each field, use the Field ID to determine the data type (e.g., integer, hash, account address) and then parse the binary data accordingly. The length of the data can be fixed or variable, depending on the data type.

4. Convert to Human-Readable Format: As you parse each field, convert the binary data into a human-readable format. For example, account addresses can be converted from their binary representation to the familiar base58-encoded string with an 'r' prefix.

5. Reconstruct the STObject: Combine the parsed fields according to their canonical order to reconstruct the original STObject. This might be a JSON object for transactions or ledger entries.

6. Display the Result: Present the reconstructed STObject in a format that is easy for humans to understand, such as a formatted JSON object or a table.

A binary visualizer tool would automate this process and provide a user interface to display the results. Here's a conceptual example of what the tool might show when decoding a transaction:
