Why is Monero highly resistant to dusting attacks?

Amounts and ownership are hidden, so dust can't trace you Each output is locked to a single unique stealth address forever Ring signatures cap how many outputs a transaction can ever spend Wallets silently reject any incoming output below a dust threshold

What does multisig provide?

Stronger amount hiding than a standard single-key wallet Multiple keys must approve a spend Automatic recovery of funds if one key is lost Lower fees by batching several spends into one signature

Why keep keys on a hardware wallet?

It syncs the blockchain faster than a software wallet It backs up your seed to the manufacturer's servers Keys stay offline and sign internally It generates a fresh seed phrase for every transaction

What does spending two of your outputs together as inputs in one transaction reveal?

What is the privacy risk of consolidating many small change outputs into one transaction?

It shrinks the ring size used to hide those outputs It declares those outputs share an owner, linking them together It locks coin control until the consolidated output is spent It publishes the precise value of each change output on-chain

Which two properties of transparent chains make dusting attacks effective there?

Exchange KYC records tied to every confirmed transaction Predictable block times and a public mempool fee market Visible amounts and visible linkage when inputs are spent together Reused stealth addresses paired with encrypted amounts

Why is a 2-of-3 multisig configuration popular?

It lets the holder of any one key veto a malicious spend It encrypts amounts that a single-key wallet would leak It survives the loss of one key while preventing any single keyholder from spending alone It splits each spend across three transactions for privacy

In an air-gapped cold-storage workflow, what actually crosses between the online and offline devices?

The spend key is briefly loaded online to authorize the broadcast An unsigned transaction goes in and a signed one comes out, while the spend key stays offline The view key is moved offline so the cold wallet can detect incoming funds Only the ring decoy data crosses, since the offline device broadcasts itself

Q10
