For example, imagine you have collection cards, with 100 cards of A, 50 cards of B and 10 cards of C. Then:
- you can distinguish the concepts A, B and C, so we say this is a kind of not-fungibility,
- you cannot distinguish between two cards of A, so A is in itself not fungible,
- you can distinguish the concepts bitcoin and ethereum, so we can say that cryptocurrency is not fungible
- you cannot distinguish between two units of bitcoin, so those are fungible
In that sense, I decided to believe that semi-fungible is not a meaningful concept and conversations should avoid this term. They should instead precise the concept, is it subsumption, multi-token, …?
I believed that semi-fungibility was kind of some useless buzz word, but some one came to me with a definition that actually made sense.
semi-fungibility could be the property of something that is used indistinguishably, while still being distinguishable in need be. For instance, banknote are used indistinguishably, but each one has an identity.
That definition totally makes sense and gives substance to the term of semi-fungibility.
I don’t know, though, whether it is used in real life with the shitty meaning or the meaningful one.
