#2One of the under-explored uses of the blockchain is as a decentralised permissionless append-only log for tracking custody and authenticity of physical products. This is also an area where a mobile app is well suited, since users should be able to add to the log and check values on it wherever they are, and ideally with a quick snap of a QR code or tap of an NFC tag.
Imagine that a mass-produced tech item from China came with a QR code certificate authenticity, which the end user could scan to check that the item had been made by a specific factory and a specific company. (The company could also add extra metadata to a blockchain to detail how the goods travelled and which are the approved importers).
The QR code should presumably have extra information in it which ties it to a serial number baked into the silicon of the purchased item, but there are other ways (based on double-spend prevention) that you could confirm a given QR code hadn't merely been duplicated.

#3Where is the money for mobile app developers, period?
I've yet to see the first person in my personal network reaching a state of being able to make a living from mobile apps (and obviously, I'm excluding the survivor-bias stories from the media here).

#4The only significant business in cryptocurrency is trading cryptocurrency[1], which is huge and very profitable. Non-cryptocurrency uses for blockchains haven’t taken off (mostly ideaware around immutability).

That's a really cool idea, but what on earth does it have to do with blockchain? Wouldn't it work better with a trusted 3rd party centralised system?
Issues I see: - Does every phone now need to store the entire log? Otherwise, who do you trust to give you the current state? - What prevents me faking a log? Why would people be doing constant work on the chain to prevent it?

The trusted 3rd party could be maintaining a blockchain. Blockchains don't have to be decentralized, they're just a type of db that can be decentralized.

Freelancing for clients provides good money for mobile app developers.
There is too much luck and handing over control to appstores or betraying your users involved to reliably make money on your own apps.

#8Any good resources for proof-of-work pseudo-code?
I am having trouble wrapping my head around the implementation, not theory, of blockchain (ledger entry based on previously hashed ledger entry).
Like, how is the beginning of the ledger created/determined? Is that just a nonce/IV?
How is each entry calculated and/or verified based on the previous entry?

You can do proof-of-work without a blockchain and have a trusted 3rd-party entity, like hashcash...

Exactly, there may be non-pyramid scheme money in crypto but so far there is no evidence for it. Look at the daily average users for Dapps here:https://www.stateofthedapps.com/rankings
They are absurdly low. Like less than 100 users a day for anything that isn’t a exchange.
Many of these dapps have market caps in the hundreds of millions with a few dozen users per day.
