With a conventional database, the owner can set any value to anything they like. With a private blockchain (and smart contracts), the owner can't forge values.

With a conventional database, the owner can set any value to anything they like.
With a private blockchain (and smart contracts), the owner can't forge values.
For example lets say you want to fake a transfer from client A to client B. In a traditional database, the owner can do that. With a blockchain, the owner can't.
- dev1n 10y agoThe owner of the blockchain can of course forge values! The computational power of the network of a private blockchain is fairly easily overcome.
