I will assume you mean the nonce that bitcoin miners iterate. Depending on e.g. wallet software other salts or nonces may be involved. That nonce is only used once, because every miner1 will be hashing a different transaction block (hash) – one which sends the reward for solving the proof of work to their address. A miner could reuse a nonce but they would ...

If I understand correctly: You have a 256-bit master key $K0$ Generate a random 128-bit value $N0$ and set the last bit to 0 Generate a 256-bit keystream $K1$ using $E_{K0}(N0)$ || $E_{K0}(N0 \oplus 1)$ Generate a random 96-bit value $N1$ Using $K1$ as the key, and $N1$ as the nonce, encrypt your message with AES256-GCM, and authenticate $N0$ as associated ...
