I wonder what the average time the user will disconnect it after they don't get paid?

It may be worth it to just sacrifice it after a month. I am sure it is profitable, but as people become more aware, it will be harder for them to do this.

3 cents per user per month. Is that right?

Is it hard to make 3 cents a month from a user?

3 cents more than what you were making before. It's free money

My college used to do similar. If you did not register your MAC address, you would be DHCP assigned into a walled-garden IP block.

We found we could run an IP scanner on the authorized subnet (from a computer with a whitelisted MAC), and find the unused IPs, and just set those statically for 'visitors'.

No need to register any more MAC addresses.

I doubt they were very concerned with you or your friends. 80/20 solutions.

Only had problems when a classmate was running routed.

Oh, and all authorized IPs were in a public address space.

Out of curiosity, you couldn’t just guess them based on knowing a couple? Or do people assigning them in some fashion that isn’t consecutive within the block?

yeah, definitely not consecutive.

You simply weren't that much of a concern. DHCP snooping takes care of that problem quite well.

No, but if you accept the answer, you get $15.

I am just curious of the age group here.

My redis is bigger than your redis?

This sentence seems especially peculiar when you take into account that the word "redis" means "radish" in Estonian.

Funny that Redis has en edit distance of 2 with certain word... and also rhymes with it.

Have you worked in manufacturing with ERP systems and BoM transactions?

I could see how this would be useful for medical device manufacturing, especially something like a pacemaker.

Indeed I did. Thing is, I see how blockchain could help existing processes. I just don't see the revolution yet. Which puzzles me, since on the one side I see the potential but on the other hand I still fail to see a real use case. And that introgues me quite a lot.

I can see its applicability in any kind of chain of trust for distribution of physical goods that have a potential to be counterfit or improperly handled/processed.

Also, I see a possibility for licensing/DRM of some types of media IP.

That does not mean it needs to be distributed, though.

Service records for the life of the car.

Vehicle purchasing/financing paperwork.

Inspection tracking.

Is it necessary to be based on the prefix, or can it be implemented by pattern, for instance, every even byte is zero, or the 4 bytes after the first 3 bytes must be all 7s, etc?

Is it simply brute-forcing hashes, looking for matching patterns that are not yet known?

I don't see what prevents you from adding complexity.

And yeah, but it also requires valid transactions if you want to collect fees, as well as the knowledge of the valid previous block.

In practice Bitcoin treats SHA-256 outputs as integers, and requires them to be under a certain limit, based on the current difficulty.

That way we can make small adjustments to the difficulty. If we actually used a rule like "this many zeros in hex", the difficulty bumps would have to be rather large.
