It depends on the blockchain:
- Bitcoin uses UTXO to avoid double-spending which means that you don't have to think about a nonce when sending a transaction.
- Ethereum, on the other side, relies on a global state. Thus, it needs a nonce to keep track of each account's transaction order to avoid double spending.

P.S.: you should be aware that nonces are also used by miners in PoW, but these are a completely different thing. If you are not a miner, there is no reason to think about them.
