Registering stake addresses on the blockchain

Once you have generated your stake key pair and stake address you need to register your keys in the blockchain to be able to later delegate your stake to a stake pool. 

This is achieved in two simple steps: 

1. Create the registration certificate
2. Submit the certificate to the blockchain with a transaction

Note that this transaction, apart from the regular transaction fee, requires a key deposit which you get back when you deregister the key. 

Create the registration certificate:
