Not sure whether this is the right place to post this question, but I’ll try my luck.
My attention was drawn by Ignacio Hagopian (https://firstname.lastname@example.org/algochat-a-public-chat-on-algorand-testnet-f59bb2d15417) that the command
goal clerk has a flag
-noteb64 that apparently can hold arbitrary data. My question is how many bytes can I send per message? Is there a maximum? If so can I increase it in the SDK for example?
