I was looking at a freshly synced node and comparing contents synce I was adding indexation and testing new ways to keep data indexed and i realized that blocks that were recently sync’d have fields that old blocks do not have. Specifically I was looking at block 11373 in a new and one old node, and i see a new “info” field that has a string in the form of “cb_” string that appears to be base’d (either 58 or 64). I assume cb_Xfbg4g== is the empty string and those are the checksum of empty.
But it caught my eye that the field is not in all the nodes I checked.
It seems to me as if there is new code that returns this field, and if it is empty it returns the field with an empty strimg, checksumed, base64. Instead of not returning that field at all.
Is this normal and expected?
