Write readable note in message pack

General
1

Hi guys,
I tried to write the “notes” field following this tutorial (py)
https://developer.algorand.org/tutorials/v2-read-and-write-transaction-note-field-python/

Everything works fine, but the message is readable in Editor View (divided into 16-byte blocks).

Then I saw this transaction
https://algoexplorer.io/tx/44S5DIVZCEWSULBN47CMSDKPV2JXNAO5OGXIGCTJVJF6LTSTMTXA

where a clear message is readable in “Message Pack”.
How do I get this result in a normal transaction?

Sorry if the question is trivial, I’ve searched around, but I can’t figure it out.

Thanks :slight_smile:

To get it readable in “Message Pack”, you need to encode your object in MessagePack format.
In Python:

import base64
import algosdk

note = base64.b64decode(algosdk.encoding.msgpack_encode({
    "firstName": "John",
    "lastName": "Doe"}
))

Don’t feel bad, how to encode and decode and puzzle out what was done to some value will haunt you everywhere in your journal into cryptocurrencies… I’ve spent days poking at it.
