What to do to start forging, it still says my effective balance is zero.
publish pubkey
wait 1440 blocks.
Yo don't have to publish public key to forge. Forging itself (if you find a block) will publish public key. 1440 confirmation wait is still needed.
By the way, how many total NFD coins? 4 billion or 10 billion?
Need to have an outgoing transaction to generate the public key.
e.g. send some nfd to self, or register an alias, then wait 1440 blocks to forg.
