1. What two pieces of information are shielded on Verge?
The two pieces of information that are shielded by Verge are IP addresses (through Tor-wallet integration) and a transaction’s recipient’s wallet address (through dual-key stealth addressing).
2. What information is NOT shielded on Verge?
Transaction amounts are not shielded on Verge.
3. Suppose Alice sends 15 XVG to Bob, and Alice’s and Bob’s ‘Master Public Keys’ are publicly known. Describe how an attacker could link Bob and Alice together, even using the privacy features mentioned above.
An attacker could link Bob and Alice together through the transaction amount. Though dual-key stealth addressing allows for users to shield where UTXO’s are being sent, an attacker could link these addresses by looking at the time between one UTXO of 15 XVG and one input of 15XVG on the explorer. Stealth addressing is also optional which leads to more potential vulnerabilities.
