As I said, blockchains are useful, but they cannot solve any problem. I still keep to my words. I do not see what is the advantage of a chain compared with other methods.

For many scientific experimental devices (this is the relevant part when data taking is at stake), dedicated (centralised) infrastructures are often more suitable. For instance, for the LHC, see here. If you take Virgo/Ligo (gravitational waves), data is released 1.5 years after being taken so that anyone can use it and check it (see here).

Those are two examples I have in mind. For anything else that is not particle-physics-related, I of course cannot tell.
