Hi Apostolis,

Are there any news on the Project? Be-D-O-SA documentation?

I'm afraid to tell you there are no news from my side. However, I cannot
speak for the BeDOZa part because I'm not involved in its development.

Is it practical to use VIFF for a P2P application where peer loging off is
unpredictable? Could their data be mirrored to another peer while keeping them
secure? How does mirroring change the 'n/3' assumption?

I'm not sure what you mean by a P2P application. Some MPC protocols can
handle disconnected players (considering them as being malicious),
however, VIFF will simply abort in such a case. In theory, data could be
mirrored. That would mean that the corruption of a player mirroring the
data of another one accounts for two corruptions. VIFF does not
implement this possibility.

I envision designing an economic system which will be based on having all the
information. If I am correct MPC also protects against anyone playing agaist the
rules. So MPC also makes such a design enforcable.

All plans of using MPC (that I know of) go in this direction. However,
keep in mind that MPC is relatively expensive in terms of network
communication and computation time. The latter is especially true for
VIFF, which is implemented in an interpreted language.

Please continue updating this project and making it more practical.

I don't have plans of adding features to VIFF. However, I'm happy to
assist with problems and to include patches that I receive. Moreover,
what do have in mind when you say "more practical"?

Best regards,
Marcel
