Why r is reused and short ?

[mristerduje]

Hi i figure out that when you make a r-scan of some addresses it comes out like this

In Input NR: 2[global increment]

Resued R-Value:

In Input NR: 3[global increment]

Resued R-Value:

empty r value

or like this

Resued R-Value:
883afb923aa9b27e98e7433d406fff17cd56
In Input NR: 75[global increment] 160014d23a0b48af87476bc3aea2b229b70f18743cf81b

short r value

what does this mean, both are my addresses and start with a 1....

i read about it test it and boom ... makes me a bit nervous.

What are you using to do this "r-scan" it may not even be correct.

Resued R-Value:
883afb923aa9b27e98e7433d406fff17cd56

This is 18 bytes and chances of you actually producing this at random, even with a weak random, is extremely small.
If you post the address on the blockchain that you think has this R it would be easier to figure out what this is.

The hex you posted seems like a P2WPKH script not R value, and it corresponds to an unused SegWit address (bc1q6gaqkj90sarkhsaw52ezndc0rp6re7qm7uhr54) which increases my doubt about you using a broken tool that supposedly scans for R values.

First, please share the tool you used for this output. I am not sure what Input NR: 2[global increment] means and from the looks of it it looks like program output.

Millions of other addresses also start with a 1 but have completely different r values for their signatures, it's nothing to be worried about. But what do you mean by "both are my addresses"? Where is the other address?

Sry was sick some days, i figure out this was not the real r value so its ok. THX for helping

R-Scan is fake util !!!
