Legit question. My knowledge of crypto is basically “bitcoin go brrrrrrr” so maybe im mistaken. But i do remember looking into a lot of projects when the crazy first set in and many talked about hosting websites that cant be shut down. Fighting censorship in 3rd world countries. Which is basically us now anyway. So... smarter than I pedes... is there something there?

blockchain is great, but it's intensive. if you want to archive text files you can do so
if you want to do so with pictures... ehh... MAYBE
if you want video you're pretty much fucked
a very short primer on what crypto actually is
text is good for certain things. like ledgers. blockchain ledgers can create immutable transaction logs, meaning very very secure money
so long as you maintain the chain and keep someone from applying computing power to the back end to unravel it
that is why blockchains generally "incentivize" their maintenance by giving people some "money" to do so. these people are called "miners" and they run their computers to do the calculations necessary to continue the chain
what they're doing is taking the results of an encryption, adding data to it (a block) and then re-encrypting it creating a chain. in order to change what's in a block you have to break the encryption of every step further along the chain, otherwise when you change the data within the block it will not match what's in the chain that's been processing the whole time you were trying to break the encryption
basically it cant be broken, because the people who would break it using their computers get paid more to simply maintain the chain than they would get risking their computing power trying to break encryption which is already hard as fuck to do in the first place
