How to import an existing delegate as witness in Graphene 2.0

Preparations in Graphene 0.9 network

We need to Extract the signing public and private key from Graphene 0.9.

Let’s obtain the <publickey>:

>>> get_account <delegatename>
[...]
Block Signing Key: <publickey>
[...]

Remark: Public keys in the Graphene network have the prefix GPH. Hence, in the case of the Graphene testnet you should replace GPH by GPH.

and the corresponding <wifkey>:

>>> wallet_dump_account_private_key <delegatename> signing_key
"<wifkey>"
