What is 'a Monero' that you own, technically?

A digital coin object held in your wallet app An entry on an exchange's ledger A number stored in an account balance One or more unspent transaction outputs (UTXOs)

If ring signatures hide which output was really spent, what stops the same coin being spent twice?

A central ledger that tracks every wallet balance A unique key image recorded per spent output that the network rejects if reused The sender's public address printed on the chain The mandatory 10-block confirmation lock

How does Dandelion++ obscure where a transaction entered the network?

It encrypts the transaction amount before broadcast It passes it along a random stem of nodes first, then fluffs it out widely at a random point It bounces the transaction through several relay servers first It delays each transaction by a random interval before sending it

How does Monero's penalty mechanism keep block size growth in check?

It raises the fee required for transactions in oversized blocks It rejects any block that exceeds the median size It enforces a fixed permanent maximum block size like Bitcoin It deducts a penalty from the block reward when a miner exceeds the median size

When you send Monero, why does your wallet create a change output back to yourself?

Because outputs are spent whole, so the leftover comes back as a new change output To keep part of your balance on a separate subaddress To set aside the network fee for the miner Because the protocol caps how much a single output can send

Q10

In RingCT, what do range proofs (Bulletproofs) specifically prevent?

They prove the sender owns each input being spent They hide which output was really spent They prove hidden amounts are non-negative, preventing hidden inflation They verify the transaction fee was paid correctly
