I found the site's architecture quite interesting: It uses inline JS to transform the Markdown in HTML. view-source: https://jott.live/markdown/elementary_blockchain Ideally it would be as a Service Worker that pulls pages and transforms them into HTML, so you could serve your Markdown directly, without a separate build step.

Looks like someone missed the buying opportunity lol.
If they held bitcoin would their opinion matter more or less? Why should it matter?
Earlier quoted context omitted.
I would contest that assertion - some blockchains regularly change their PoW algorithm in an attempt to stay "ASIC-resistant."
That simply makes two currencies - before-fork, and after-fork. There's no rule that the one that "should" win does, especially in the face of large computing power making the former more attractive. See Bitcoin Cash, versus Bitcoin Classic.
IIRC it didn't work for long (the of promoters of these tokens were likely well aware of this), and ASICs for them appeared anyway, once an ROI probability threshold was reached.

I guess in a way comments like these are actually a really good indication that PoS is superior in virtually every way.
If there's no shortage of bricks, and those bricks can't be used (or exchanged) for anything other than the material for making the tower taller, then of course that would be pointless.
But that's not how cryptocurrency works. The whole purpose of proof-of-work is to protect the attribute of scarcity in a distributed way where one actor can't control (or change) the rules.

If I squint, I can almost pretend I'm insulted that my browser/Javascript had to render the Markdown instead of their server doing it.
I can't see how their infrastructure is making any real savings by doing this. There are usually more reasons to just cache the HTML next to the input Markdown. e.g. You can then make money breaking changes to the transformation without breaking old posts. Not to mention it now kinda pointlessly needs Javascript to do something trivial.
Unlike what seems to be the prevailing opinion on HN, I'm quite pro-Javascript and pro-SPA. I never saw the need to damn webpages to server-rendered HTML just because it's the only client/server system with the quirk of being able to send markup from the server.
But this sending Markdown over the wire with a 24kB Markdown script + `$('post').markdown()` is just cheeky. ;) Does it really matter though? Nah.
Each student keeps track of which of the others they consider trustworthy. Since they all play together everyday, they know who is nice, and who is naughty.
When a supermajority trusts the student placing a new block, that student is allowed to place it anywhere.
When not enough people trust the student placing the block, they prevent that person from doing so. That person may try again, but until they're willing to play nice and act trustworthy, they cannot place any blocks. They sit in the corner and pout until they come to their senses.
No one has to solve any puzzles, or roll any dice.
The tower is built efficiently, and all sorts of interesting designs are made by the creative energy that would have otherwise been wasted on busywork.
Funny. The first class was a public class & anybody could join in at any time. The second class had reserved early seats based on the initial supply of the dices; without investment in the initial dices the game doesnt start, whereas sudoku generation is free.
