You just pointed it out yourself. You can't really modify historical data on a blockchain. So instead you'd need to create separate blockchains with separate histories. That's the value. If you have a centralized but public blockchain you can't really go and swap it out or everyone is going to know.
- Retric 3y ago> You can't really modify historical data on a blockchain. On a private chain you can easily change the data. Remove the hashing fig leaf and it’s even easier. On a public one it’s the public nature that prevents changes after publication. So no, being a blockchain doesn’t prevent changes whatsoever. Having a public ledger does.
