No no, thank you for this.
I understand blockchain as a concept, and kind of hownit plays into cryptocurrency, but understanding a true example of blockchain use outside of finances is something I needed more info on, thank you

This can also be used for research institutes to be able to research with each others’ findings.
Here is a paper on the topic: www.ncbi.nlm.nih.gov/pmc/articles/PMC8555946/
Blockchains are also great for the verification of digital goods as tangible assets. While I’m not sure we reach this level of meme ^, people could 100% mint their own house’s deed and trade that as a legit way to buy/sell their house.
I am very carefully avoiding the words “NFT” because they are another horrible use-case of a blockchain (and a prime example of how capitalists turn a good tech into something stupid for a quick buck), but this would theoretically be a tokenized-security with a 1:1 to the actual deed to the house.
Is that more secure than the normal process of buying a house? Do you really need it to be external to a 3rd party when the transfer of homes already exists? No not really lol, hence why we probably see it the most in highly regulated industries like biotech and finance first.
HIPPA/Securities-laws (or lack-thereof) will require a tough regulatory framework that “could” realistically be done via a 3rd party, but you have to ask yourself if you trust big-pharma and wallstreet enough to regulate themselves like that.

The big improvement is the removal of the need to trust some 3rd party but also to add the precision and complexity of computer language to some domain. For example health care data, a block chain system would make one standard for how the records are stored, it would make it so the data in encrypted by the patient and they alone could grant access. When a new provider wants access there is one standard way that is automated and secure. None of which is dependent on a 3rd party who can be compromised or become corrupt and no longer act in good faith. Obviously there is a lot of details here dependent on making the block chain work flawlessly.
Imo block chains have 2 core issues to over come in order to really solve problems. First is being constructed so that they are bug free. Software is not a mature enough discipline for that as of yet. Second, is what happens when you loose you key or it gets stolen. If someone steals you Bitcoin private key, you can’t get them back after they transfer them out. Or if you just loose the key your up a creek. What is required is a way to prove you are you to the system that can’t be stolen and can’t be lost. That is a far harder question.

I just wrote out another comment, and I think I kinda figured out my core question, but, is there a way to save my medical information without doxxing myself, if this is supposed to be like, a public database, you know, if that’s kinda the point, is that everyone can look at everyone else’s stuff? I got the impression that a lot of the current blockchain stuff wasn’t capable of the necessary levels of storage that would be required for like, health records, on their own.
I dunno, maybe you could have some situation where you have a key, that opens up some cryptography on the blockchain, and that blockchain piece when unlocked gives you another key that lets you access your medical records, or something like that, and that might be able to fit. But, then, I don’t really see how that’s any different from just having like, the key to the person’s medical records be contingent on person. Like biometric security, or government ID, or something.
Point out wherever I’ve made wrong assumptions here, I’m just kind of talking out my ass, and hoping that I’m correct inso that the conversation can continue and I can scrape more out of it, I don’t really expect to be right.
