Versions of protocols for BTC and TEST? I'm dorking around with creating a TEST transaction using libbitcoin's bx command.  Besides setting the inputs and outputs, the bx tx-encode sub-command allows one to specify lock_time and version.  Any idea where one can look to find details about what the current version is for BTC and TEST transactions?
You should use TX_VERSION = 1 and TX_LOCK = 0xFFFFFFFF for mainnet and testnet
