When someone when to search for this transaction does it need to iterate all blocks am I correct?

1. Phase 3 vine in urmatoarele saptamani. Schimbari majore nu o sa fie... Staking si delegation se va face la fel, doar ca o sa fie mai multe locuri de validatori. De la 2169 vor creste la 3200 de noduri. 2. Daca zici de numarul minim, ne gandim ca a ajuns valoarea de 10 EGLD la 2000 de dolari... care nu mai e foarte mica :)

Depending on what you know about the transaction. If you know the hash of the transaction its a simple lookup, if you know only some informations, like the sender, receiver, data, time etc. you will have to use the api (which utilizes an elastic search instance with all data indexed) :)

Who's that admin? Whats his name?

Yes, publicly

I just realized that all 4-5 I looked at their profile and we have no group in common. It must be a fake group ???? I'll investigate more
