InternetJunky posted:MAN WHO CAN’T REMEMBER BITCOIN PASSWORD SAYS HE’S ‘MADE PEACE’ WITH $220M LOSS Wait, the article says 18.5 million bitcoin are currently stranded or lost due to forgotten passwords and such (idk how accurate that is). Isn’t the maximum amount of bitcoin set at 21 million? Is there some way bitcoin that isn’t used after a certain time destroyed or is it only a matter of time before all bitcoin is lost?

ikanreed posted:B. You absolutely cannot under any circumstances publish individually identifiable medical information in any way, so the identifiable characteristics like sample IDs must be encrypted. Either that or kept entirely within one's own walls and directly sent to only stakeholders. At the very least this rules out a traditional database.

kw0134 posted:What? Why? Are you going to memorize the sample ID and swallow the paper it was written on? Why isn't an anonymous sample ID not good enough? What kind of identifiable info can you make if you created a random string like 3325dg2351vard for your sample ID? The key to deciphering the referents is kept within the provider's walls, isn't that sufficiently secure? Legally speaking, an anonymous sample id is considered "at risk" for becoming identifiable when combined with date, time, or location information. It's okay to share within limited circumstances, such as medical research, that don't directly pertain to a patient's care, but should not be made public.

I've seen exactly one use case for blockchain that sort of makes sense. Gemstone diamond chain of custody tracking. The story goes like this: A. The entire industry is controlled by a few extremely corrupt, extremely secretive companies that regularly do business with warlords, profit from human slavery, and ignore genocides on their doorstep. B. For a long time they had a monopoly over shiny rocks but this is changing because we've finally figured out how to make a shiny rock in a lab. C. The only hope that the evil companies have to continue existing is convincing people that lab-made rocks are somehow inferior, and part of that includes pretending to address the ethical concerns. D. A blockchain of unforgeable crypto is a really great distraction to point at and say "look! look! this proves we aren't doing any of that evil poo poo!", while they continue to do just as much evil poo poo. E. There's a sucker born every minute. All that sort of seems to work as an actual use case for blockchain, because blockchain is an excellent source of handwavium to fool people with so they stop asking so many questions.

This is a solution that doesn't actually solve any problem. Encryption, nominally, should establish identity. That's just a technical idea and a key can be broken, stolen, or otherwise compromised, but there should be only one private key that produces information that can be decrypted by a given public key. If you don't posses it, it shouldn't be possible to decrypt the blockchain record, add your tag and re-encrypt it. You know how your browser complains if a website has an inaccurate certificate, that's the same idea in a different setting. Only the "real" website should be able to correctly encrypt the resulting pages.

kw0134 posted:Then I'm not sure how you can get literally anything done. The sample has to be identified, that identity has be made visible to at least the persons handling it in any material way so it can be tracked. Moreover I'm still not seeing how a publicly available ledger like a blockchain makes this more secure since you have to call the sample something, and that something is trackable on said ledger (and if it can't then you've created a write once, never read database, because you've created a bunch of data not fit for the purpose.) You receive the sample id with the sample. No reason to know it before then. That plus retracing the steps of previous chain of custody using the attached keys and known public keys can recreate the history to the extent your organization needs it. Your own record is an entirely new one encrypted both the with the attached key and yours. Remember that the primary function here isn't reporting results, but proving chain of custody electronically. Reporting usually has its own channel of communication and doesn't need to involve middlemen.

This. The suggestion of blockchain for medical purpose shows an absolute lack of real world knowledge on how hospitals and other medical clinics operate I also don’t see the reason to have a decentralized record when there’s clearly one coordinating organization (the clinic) and several other orgs taking care of a piece of the work. That’s just centrally pseudonymized ID number -> other orgs do their work and send it back -> coordinating clinic uses key list to match result to real world person. Anonymous medical data doesn’t exist given access to enough circumstantial data and efforts to anonymize data shouldn’t make the actual work harder or research (on which the actual work is based) more difficult

If I'm the middleman in the chain of custody and I've been paid off, I can switch the hot russian olympic pee with regular pee and sign the blockchain. Exactly the same as if I was signing a piece of paper. The work (transporting pee samples from the olympics to the lab) is completely divorced from the proof (signatures on paper or blockchain), therefore the fact that a blockchain can't be tampered with is completely useless. The piss is the important thing here.

Any potential application for a blockchain runs into the problem that essentially the only application in which a write-only system without any ability to clear out mistakes is acceptable is illegal activities where you don't give a poo poo if there's something bad in there. At the very very least you need a way to clear out the bad data and store a record of it being cleared out, why, and who authorized it. Blockchains as an immutable record are fundamentally incompatible with the rule of law. Blockchains which can be altered are fundamentally stupid.

I’m still not understanding how bitcoin can persist if it can constantly lose coins due to lost passwords and wallets and has a maximum supply of 21 million coins. Is there some way to increase the max? I read there are “protocols” to increase the max but it sounds like made up garbage to hide the fact bitcoin will eventually disappear.

That's not really a problem because they are infinitely divisible. Imagine 18.9 million bitcoins are lost into the ether and the supply is down to 2.1 million. Nothing has changed, they are still worthless but the rubes will transact 0.0001 btc for their [whatever you actually might buy with crypto] instead of 0.001

Green energy still costs resources to build and requires carbon emissions. Green energy could still be used for something productive instead of duplicating more and more of the same pointless work. If mining demand is such that additional energy capacity is provisioned we're still losing. The only time green energy is a selling point is if you have a hydro dam or your country overbuilt wind/solar/nuclear and there's lots of excess power that would otherwise go unused. Then you're effectively energy neutral. When you get into hardware, space issues, or that most places do not have significant excess power it all falls apart instantly. It's pointless feel-good, achieve-nothing garbage. If adding more nodes to the network increased its capacity or efficiency then there is some argument that green energy is good. But it doesn't. It does nothing except waste more resources. The network runs just as well when the entire network is a handful of $30 rpi as it does when the network costs hundreds of millions of dollars as it does today.

If 90% of bitcoins are lost forever doesn't that make the market cap of bitcoin actually just ~70 billion instead of 700 billion shown on the trackers? And in that case, doesn't that mean that tether (which is close to 60 billion cap) is literally propping up 85% of bitcoin's "value" with absolutely nothing behind it?

The Bitcoin protocol can be changed if enough people agree, it has happened multiple times before - and if the majority doesn't agree, but a significant enough minority, you get forks like Bitcoin Gold or Bitcoin Cash. It's computer code running on computers programmed by humans, not the laws of physics.

I always had the impression it was made and sent out into the world in a way that no one really controlled it anymore, it just exists now. The idea of people mining bitcoin answering yes/no to some random poll of what to do to bitcoin seems odd especially since it sounds like currently that’s mostly the Chinese.
