Part 11/13:
To enhance privacy and resilience, Shapiro discusses deploying multiple blockchain nodes simultaneously—potentially on personal devices like smartphones, local servers, and cloud infrastructure. Data encryption remains essential, as storing raw data unencrypted would risk privacy breaches.
He observes that as long as the initial blockchain ledger (the "genesis block") remains secure and intact, the entire data chain stays trustworthy. Remotely deleting personal data or compromised devices won’t harm the overall integrity of the data system if the blockchain is encrypted and properly maintained.
