Oh wow, honoured to have you here Nathalie ! Thanks for the clarification. I guess I'll need to go step by step through the process to be able to argue in depth. What for me makes the difference between "simple" and "rudimentary" is that the actual certification information is not ON the blockchain. You only store a hash on the blockchain. That means for instance that an employer who looks for a fresh graduate in, say, climate science with a minor in computer science cannot go find some potential connection information on the blockchain. He neess to employ another system for that.
If the AlignmentObjects were ON the chain then one could query directly the data on the chain and possibly find DIDs of people who want to be found easily (because they want to leverage their diploma and find a job)
