I'd found these two transactions:
They're related to the SegWit address 3AQ4kUjQaDjCjmDh2ojKEHjUKTSi52UUqD.
I don't understand much about SegWit addresses transactions but it looks like the first part of each transaction has the same R Value 145d3cbed9f338b82667f410340fcb9bf401c7e837e9f4539b915fb8bced (if this is the R value).
Is that address private key compromised?
I readed something about using the same R value can be used to get the private key of an address.
(Even with the same R value used in transactions from different addresses, but only if you already know the private key of one of those, with something like
k = ( digest + r * privkey ) / s or so, I didn't found more about this case).
