AI translates the explanation and quiz text while preserving code and answer scoring.

Move was designed by Meta/Diem as a safe, formal-verification-friendly language for Web3. It treats assets as linear Resources that cannot be cloned, accidentally dropped, or double-spent.

move
module my_addr::counter {
    use std::signer;

    struct Counter has key {
        value: u64,
    }

    public entry fun init(account: &signer) {
        move_to(account, Counter { value: 0 });
    }
}

In Core and Aptos Move, resources are stored in global storage indexed by the owner's account address.
