Spain will prevent “digital republic” in Catalonia

Short answer: no, just from Spain.

Long answer: while the biggest part of the movement is pro-Europe there are voices from the left-most & anti-capitalist part which are against EU because they see as an union that put money first instead of people. But as said, they are a minority among the independentists.

It has very close ties with Carles Puigdemont, which has been his director once.

It's the typical second biggest city not having internal relevance compared to the capital even though it's as good, together with the common claim of everything happens in the capital, decisions are there, most money stays there, etc.

Also, it's slightly different culture, language, etc. And around WW2 time, there was an actual civil war.

Discontent keeps happening, catalonian patriots gets in power, central government remembers that constitution prohibits secession, they do a referendum anyway, (90% win for getting out), get arrested/exiled, with draws bigger attention to the cause, Streisand effect and all that.

Spain issn't really an united nation, you have actual separatist terrorists in Basque (which have a peace treaty recently), the new separatists of Catalonia, Andaluzia has seen the rise of dissidents as well. Add to the fact that some regions actually have their own language.

I remember one time while crossing the border by car, seeing a tourist information sign vandalized because in was written in Castillan (language of the capital, main "spanish" language). Beneath all the vandalous paint, was a sentence: "speak the ". And this was not in one of those more dissindent regions. Later I got into the city, and every sign was in multiple languages

Irrespective of this, Spanish Constitution has a very strong enforcement of Spain's sovereignty and unity. It belongs to all Spanish people. So if that is to be altered --i.e., any region wants to secede-- is a decision that must involve every Spanish citizen. So in order to proceed, either everybody needs to participate in such a decision, or the Constitution needs to be amended. The separatists do not want to proceed either way, so they are trying to do it "unilaterally". That's against the Constitution, and the State needs to protect itself from that.

Anyway, if Catalonia would eventually and legally secede from Spain, it will be automatically out of the EU. And in order to gain access to the EU, it would need to apply and be approved unanimously by every EU country. In other words, Spain may veto that.

My opinion: it's shooting yourself on the feet. I believe they never intended to secede, they were just pushing this road hard to negotiate better financing and money for Catalonia. They have been doing this for many decades. But this time they took it too far, lost control of it, and now they don't know how to back track it.
