Mining too
Mining simply refers to rewarding nodes that work to verify transactions. A blockchain can exist without distributed verification, and without mining.
Example?
Medical records on the blockchain – the history of a bad idea

so...why are you still the CEO of a medical blockchain startup? Surely you escorted yourself off the premises by now? ;) But seriously, isn't this putting the cart before the horse? The usual order is "find a problem, build a solution", not "find a technology, build a solution, work out who has a problem it can solve". How's that working out for you?
There might be potential uses for distributed ledgers in an industry that is required by law to share your care history. This specific company not having arrived at a concrete product does not negate the potential upside. All it takes for them to do is develop a technology that can be of interest to an industry giant and become acquired. Im not saying this is the case here, but it is a real option.
We're only required to share the history of care you have with us, which is easily achieved with a standard database. We communicate with other providers using standard protocols that are implemented by every EHR system.
I struggle to think of a use case for this in healthcare.

So they _really_ mean git.
Right. When the biggest advances in blockchain are really in consensus.
Sure. Which is, as the parent comment pointed out, rarely one of the things people trumpeting "blockchain" need in the problem domain they're proposing to deploy it.
I don't need global PoW or PoS consensus for my health records.
I need something my health providers and I can agree is authoritative and as accurate as the data entry makes possible. The parent comment's "immutable, distributed, cryptographically-verified database". Something like a shared git repo. Not like a crypto currency.

> How's that working out for you? It's a slow process, for exactly the reasons you describe- in fact, I've quoted that exact same line of reasoning many times myself. The reason to work in this area regardless is because there are definitely large opportunities long term.
That's interesting, and refreshing honesty :) thanks
If you don't mind me being more nosy, are the long-term opportunities in this exact line of business? (i.e. do you think that one day medical records will be routinely stored on a blockchain?) or is it more than developing skills and capability with both blockchain and health tech will be valuable in the future?

> Where cash is still a better alternative. I suspect not too many drug dealers or gun runners want to wait around 20 mins staring at their phone (with a traceable internet connection) for 2 confirmations before declaring the deal "done"...
I've read that it's done more like escrow. The buyer creates a new wallet, the seller verifies the amount in the wallet, and then the buyer hands over the keys when the merchandise is transferred.
That's smart.
The seller still needs to make sure the buyer can't get a transaction transferring the coins back into a wallet under their control confirmed before the seller can move them out.
(I'm now vaguely curious about how the financial transactions on shipping container sized sales of guns/drugs work. But I'm not about to Google _that_...)

* Decentralized, anonymized reputation management. Imagine an ebay score that couldn't be owned by ebay, or any another company. There are about 500 articles every week about China's "social credit score" dystopia, and you want to put that on the block chain?
China's social credit score is centralized and not anonymous. So, there's not really much to compare.
An decentralized credit score would have you scored by your peers. An anonymized one would only be evaluable when you chose to use it.
Could it present some heretofore unimagined dystopian situation? Sure, but the question was whether there was an application, not whether it was a good idea to build it :)
Moreover, reputation systems aren't inherently dystopian (or all encompassing like a social credit score, ftm), or we wouldn't have the long standing real-world ones.

Tracking employee identities in The medical space should be done in a much more rigorous fashion, there are significant benefits in doing this on a public blockchain. Medical records MAY someday end up on a blockchain, but the benefits of this are more hazy and may never outweigh the switching costs.
Re: Medical records on the blockchain – the history of a bad idea
#98I feel its become very fashionable to dismiss the simpler applications of the tech because of how unrealistically its been applied. It's so easy to do too. Look at the insane valuations, the fraud, and hype cooked up by marketers, and the whole thing looks very stupid. But its a mistake to let this get in the way of critical thinking. There is a reason why the topic is brought up so often and its because among all th…
If you could tell me even one application of this technology outside of cryptocurrency, I'd genuinely be interested.
Land parcel record management. Especially in developing countries like India there are often cases of 'double spending' motivated by bribery. having open distributed records would make use & validation of such records more robust.

None of which you have listed can be proven by blockchain as it has proofs for today. All would rely on external sources of truth which entirely live outside the verification of the blockchain. The blockchain in these cases would be an immutable chain of unverified facts.

Okay, let’s see: how does that benefit me in real, tangible terms? What risks does it have - for example, do users take on responsibility for fraud risk?
> Okay, let’s see: how does that benefit me in real, tangible terms? It allows you to store and transfer value in situations where you either cannot obtain, or do not trust your available banking relationships. You also have much, much lower fees for international remittance. > What risks does it have - for example, do users take on responsibility for fraud risk?

This is patently false. My bank, Fidelity, lets me send domestic wires (which are virtually instantaneous) for free. (Fedwires actually cost most customers virtually nothing.) International wires aren't that much more expensive, with the majority of the cost for small transactions being antifraud. In that respect, every cryptocurrency is orders of magnitude more expensive than the status quo.
