Suppose we have a well-known photo of the Brooklyn Bridge. It was scanned twice and separate NFTs were created and sold. The data & hash is different because the scanner had different dust patterns on the glass each time. But visually - it's the same photo. And they were sold with the promise that they were unique in the world. Which is technically true (the math proves it), but a reasonable person would not think so.
A legit source like the NYC Museum of Modern Art would be trusted to sell NFTs that are unique and collectible. However "Bob's online NFT Shop" has a really nice website & sales brochure and so far has relied on his Terms of Use to quash any rumors of selling dupes.
It would take a while to explain provenance in crypto space. It's largely based on credibility and ownership of addresses. Once credibility and address is established, it is a simple operation to prove the Bridge picture came from a specific artist. Things like ENS (Ethereum Name Service) are examples of deep support for provenance in Crypto.
It’s an incredibly shady coin. No doubt it was a lot of work by Coinbase to onboard it.
Ambitious employees "know" that switching jobs will give them the pay they're looking for, because they see those numbers right on the job postings. What's less obvious is that a current employer might really value an employee's skills, and would be willing to match or exceed the competition - if they just open up the conversation.
IME it's not even (always) any kind of rational decision on behalf of management to "stiff" people. If you have a happy employee making a wage they're satisfied with (+ annual COL), then these conversations about TC may not even come up at all. It's easy to just turn on autopilot here.
If you like your job, but you're not happy with your TC, make sure you're letting management know. It could be that everybody could end up happy. Even a good manager might not be doing this for you until/unless you advocate on your own behalf.
I've had 50% pay raises that were nearly matched by the current employer. My last manager literally said the words, "What if we offered you a big bag of money to stay?". I left.
Now I work at a place where people stay literally until the die, 10, 15, 25 year tenures. My coworkers are mediocre. I'd say it's a mixture of laziness and sometimes maybe just incompetence.
It's a two fold problem. Employees that stay this long do not progress in their careers or learn new skills. I've learned next to nothing in my 5 years here. Employers that don't create churn in their workers create numerous problems. If we didn't hold a monopoly in our field, I'm sure we would have been bought out and had mass layoffs by now.
