Rebirth in the Quantum Ledger: I Rewrite the Cause of Death in the City

In Hailin City in the near future, financial technology and urban big data are highly integrated. Rumor has it that there is a "Quantum Ledger System (Q-Ledger)" hidden in the city's underlying network. It is not an accounting tool, but an underlying rule for recording and verifying "causality": everyone's key choices will be abstracted into "causality entries", affecting wealth, relationships, risks, and even the probability of life and death.
