What about Vaporware?

What does Ransom do about Vaporware (works that don't really exist)?

In the Ransom model, the Holder must release something, which is called the "Proof". They cannot hoard the Work and expect payment just because they say they do. At least some part or version of the Work must be released.

Also, the transactions in Ransom are legally binding. There are no promises that can be simply broken without getting into legal trouble.
