Stake Address Registration

Registering the stake address to the blockchain pays a transaction fee but also needs a deposit. We can check the protocol parameters to learn how much we need to pay as a deposit. We can get the deposit back when we deregister the stake key.

cat protocol.json | grep stakeAddressDeposit
"stakeAddressDeposit": 2000000,
