Has anybody tried to replay a Bitcoin Cash transaction on Bitcoin and vice versa?
I see that there is SIGHASH_FORKID flag that is used by Bitcoin Cash to sign a transaction.
The flag is used in method signrawtransaction in this source file

What about if I try to send a transaction signed in Bitcoin to Bitcoin Cash?
Anybody tried that?

hm... interesting, that no responses.
It reminds me the situation with Parity's multisig wallet when nobody checked it because they blindly trusted to "experts" who wrote that contract.
What if there is a tx replay issue in Bitcoin / Bitcoin Cash?
