Wang Xiao has the habit of keeping a ledger every night. Until one day, after recording his family’s shared expenses on the blockchain, things became awkward.

His wife’s transfer of living expenses, his child's tuition savings—every figure was as transparent as a display case. Colleagues started chatting casually, "What did you buy with that 648 yuan last night?" neighbors commented, "Your nanny expenses are quite regular." What was once private family finance suddenly became a hot topic for public scrutiny.

Later, he started trying Dusk. The same family transfers, but the results were completely different—outsiders could only see "A compliant transaction has been confirmed," while the specific amount and recipient were encrypted and hidden. It was like installing an invisible lock on the digital ledger.

For Wang Xiao, this was no longer just a technical concept. In daily life, privacy protection means peace of mind—being able to securely record every ordinary yet precious family transaction without worrying about being judged.
