Hi Bertrand, thanks for your honesty, idealism is a long term plan, I
stick to it! Anyway PUF is not ideal because the main advantage compared
to the microchip is not to require Internet connection, but I still need
it for realtime market price, so… It also seems to require power supply,
so not much advantages yet compared to microchip. Thanks for the great
source of information!

Bests,

Camille.
