Got a bit of a mystery here... I was digging into some RSZ stuff and noticed something strange. I spotted RSZ with a short S being used on two DIFFERENT wallet addresses, and they have the SAME RSZ. Does this mean there’s an issue with how the signing went down? I know it can be recovered with the keys, but that's not really my area... Just curious if anyone else has encountered this before. Thanks, P.S. I prefer not to share the signatures since they come from the chain. Edit: Upon closer inspection, I found two sets like this for the same addresses.

@MikeJ_NpC Its not security issue having 2 same R in two different transaction (two different public key) unless one of them private key you know, Without private key (D) of one of them or Nonce (K) you can not recover any of them. If you find same R in same private key (D) or public key Then its possible to recovery nonce (K) and Private key (D)

No, bro, you can only recover the private key if the repeated R value is from the same address. Why on earth would different addresses share any kind of relationship like that?
