Stats

To get some stats about interoperability of BTC and BCC ECDSA (over secp256k1) signatures, run:

$ ./stats.sh <iters>

Where <iters> is the number of signatures to generate with each signing program. If all is OK, it should output something like:

$ ./stats.sh 100
Signing... OK
Baseline (BTC verifies BTC; BC verifies BC)... OK
Crossed verifications (BTC verifies BCC; BCC verifies BTC)... OK
Stats:
BTC signatures successfully verified by BTC: 100/100
BCC signatures successfully verified by BCC: 100/100
BTC signatures successfully verified by BCC: 100/100
BCC signatures successfully verified by BTC: 100/100
