Title: Why r is reused and short ? Post by: mristerduje on March 10, 2021, 05:30:29 PM 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.

Post by: pooya87 on March 11, 2021, 03:57:54 AM Hi i figure out that when you make a r-scan of some addresses it comes out like this What are you using to do this "r-scan" it may not even be correct.Quote Resued R-Value: This is 18 bytes and chances of you actually producing this at random, even with a weak random, is extremely small.883afb923aa9b27e98e7433d406fff17cd56 If you post the address on the blockchain that you think has this R it would be easier to figure out what this is. Quote In Input NR: 75[global increment] 160014d23a0b48af87476bc3aea2b229b70f18743cf81b 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.Title: Re: Why r is reused and short ? Post by: NotATether on March 11, 2021, 04:23:10 AM 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.
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.... 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? ??? Title: Re: Why r is reused and short ?
