Oh, hey, I have a way to make private smart contracts as well.

It is called having a database and server that runs code!

[vvpan]

Yes, except you are 100% in control of what goes on on your server and could easily falsify data. The _whole_ point of cryptocurrencies is to avoid that.

Same with a private blockchain....

You are right. That's dumb. That's my entire point!

[josephagoss]

A private blockchain spread across for example, several organizations, may be a good vehicle for sharing a database in such a way that all parties know it can't be falsified.

For example, you could use a different consensus algo and enable each organization to have one vote, one mine and this would enable sharing of data that you want to ensure hasn't been modified.

This model could connect possibly thousands of different organizations together with a trustless setup.

Except it's going to be orders of magnitude slower.

[stale2002]

The blockchain solution is slower you mean.

A blockchain solution has the same code literally running on every single node.
