In-band_signaling is when you send additional data of different type in the same channel with main. For example this picture of xUSSR Venus probe has telemetry embeded in the surface image:
There has been already some occasions of sending messages in blockchain. Including sending ASCII codes and I have seen several 13117 transactions myself.
What if we kinda standardize them? BIP anyone?
Let's say the escape sequence should be two zeroes in a row and the message code should be expected to be found in the least significant decimals. That could produce many false positives but we are tight in 8 decimals after comma. The decode table could be something like this:
1-with love/respect
2-keep up the good work
3-[you name it]
These nano-bits also double as tiny tips
