apparently "full archival nodes" are on the way out. they simply won't exist anymore at a certain point other than maybe you can find a service that will let you look at old history if you pay. that's what i heard...
and there goes the "decentralised blockchain"
i know you hear things from idiots..
but although explorers do show history FOR FREE. i do understand why your idiot mentor has $$$ on his mind of making people need to pay for everything.. funny part is though your mentor is promoting capitalist ideals while he himself isnt profiting from the promotions. he HOPES one day someone will pay him. but after 6 years he is still penny pinching sig-campaigns of crap services to live on..
i do understand his ideologies is centralist capitalist(elitism) system.. but thats him thinking about fiat too much. he loves fiat
ever ask yourself why bitcoin was made to be nothing like a centralist capitalist system. ask yourself why even bother with decentralisation..
i really want you to ask yourself and seek out information from actual sources not your mentor because he is leading you into a cultish rabbit whole that wants to break bitcoin principles and just make it emulate a CBDC
