This reminds me of Nano (the rebranded xrai or mrai, can't remember honestly now). Everything was mined via captcha.
Point is, I also recall the number of threads specifically dedicated to collecting people to help solve those captchas, paying what I would say were amounts only significantly better than collecting faucets. Since this could still result in tens of dollars for a day's work, it meant a lot of willing workers - I come from a country where minimum wage is less than $200 and my neighbours in other countries generally don't even meet their much lower minimum wages. So you'd see legions of these workers mining for a handful of people.
Towards the end of last year, it got even more organised. People integrated it into faucets, drawing even more people (faucet hunters) mining for them.
That demonstrates a bad-case slavery scenario for your idea, and ensured most of the mined coins belonged to the very few with resources to organise.
I theorise that it would also still be possible for computing power to randomly attempt to solve these NP puzzles (keep changing IP and just randomly select answers) and achieve low rates of correct answers, and yet still outperform productivity of a slower human over time. I know randomly clicking captchas or always selecting the same images sometimes still solves it!

all is good myself in crypt o currency
bitcoin , ethereum , bitcoin cash ....and much more crypto currency
all are rich get rich and poorer get always poorer only concept, then how the crypto currency future of the world currency, and also the currency used for many illegal underground market , and it not pay a tax to government, and yours whom intelligent in math they get rich, then the inventor , farmers and others, what they do , if your rich you get 1000 for less work - others get 1 for very hard work , is this equal
based on money
human != human
rich human (crypto currency intelligent) != average human
when it equal develop like this

Also called Proof of Human work (PoHW)
This idea was sparked by the great and succinct riddle that monsterer2 proposed on this BitcoinTalk thread:
https://bitcointalk.org/index.php?topic=4447123.20
"A truly decentralised consensus mechanism is one where humans perform the PoW. The trouble is, finding a problem that only a human can solve that is also easily verifiable by a machine is unsolved.
The person who solves this problem will be very rich indeed. "
Ask and you shall receive.
While I do not expect to get rich ( I have solved many of the worlds biggest problems; but if it doesn't make someone else rich then no one cares) from this idea. Actually I think the opposite, people will hate this idea because they would actually have to work for their money instead of having a computer doing it for them.
I have termed this idea Proof of Human Work (PoHW). I do not claim that no computers or AI will be able to mine this. However I do claim that humans will have a fair shake at least until an algorithm can be developed to solve it (which likely will take a good number of years at the very least since these problems have been known and researchers trying to solve them for decades at least). I think the biggest risk to this proposal is the training of AI to use skills humans have developed to solve these problems.
It would probably find form in "puzzle video games". They can likely be done with paper or pencil but doing it on a computer in a program or app would be the best way to go for mining purposes.
The idea is simply this: Use NP-complete problems as a proof of work. NP complete problems are Non-deterministic polynomial time problems. An NP Hard problem means in essence that they cannot be sped up with computers. The larger the problem, the worse computers (algorithms) are at solving them. Np-complete are a subset of NP-hard problems. What NP-complete means is that a computer can easily verify a proposed solution is correct, but cannot "know how to" solve the problem. This even works if you believe P=NP (which I do), as you can create a new coin using a new NP-complete problem that has not been cracked (or change the algorithm of your coin but I always advise against this where possible). P=NP hypothesis means that every problem that can be easily verified can eventually be solved quickly too.
Now the problems shouldn't be just NP-complete, all hashing functions are designed to also be NP-complete. But the problems should also benefit from heuristics. This means that you can find ways to improve your ability to solve the problem. You likely won't be able to find any heuristics for SHA256 for example but you can find heuristics for the traveling salesman problem or minesweeper for example.
This is exactly what we want; a problem whose proposed solution can be quickly verified by computer and yet the computer would be "bad" at finding solutions itself. Perfect.
Some example problems to solve could be the traveling salesman problem and/or minesweeper, and/or any other NP-complete problem or combinations of problems. Any implementation and/or mining methods or programs or suggestions can be used. This idea can be used by itself or in conjunction with computer mineable problems like using this idea in conjunction with other PoW algorithms.
For example you could have a 100x100 minesweeper or any size or size dictated by automated difficulty adjustment and the first one to solve it win's the block in mining. A program could disseminate this to people around the world to work on it and could pool the individuals and split the reward or give the individual who wins it first the whole block reward. Also some programs can have collaboration where everyone can work on the same minesweeper problem together. There are many challenges minesweeper would pose (such as needing a trusted 3rd party to create the minefield or obfuscating their ability to see it) in this context which we won't go into, it is just an example of how this human mining could be set up.
Minesweeper is np-complete

Traveling salesman problem
https://en.wikipedia.org/wiki/Travelling_salesman_problem
Drawbacks: People have to do work. Slavery could result from this. People may need more food because thinking takes energy.
Benefits: Mining centralization will be a smaller problem. Anyone with a brain and a communication method can contribute and earn money. Even animals like bees may be able to be used to solve these (search: bees traveling salesman). No specialized hardware or even computer is needed. Energy problem will be nonexistent. Just like we don't tell people not to exercise, this will be exercising peoples brains. The whole global network would use negligible extra energy, and even if the people ate more, exercising the brain will make them healthier. It may help reduce the risk of dementia and other degenerative brain diseases. This is our liberation from the coming "tyranny of the algorithm".
Here is another whitepaper that uses the term proof of human work however it uses CAPTCHA's and not NP-complete problems. I think our idea is better and is more veritably NP Hard.

Can also be called Proof of Neural Work or Proof of biological work or proof of thought.
