My attempt at one: https://pastebin.com/SEEpx3C4 https://pastebin.com/SEEpx3C4 > Hello Hackernews, This is one. Whats so tough? 47d751f8964d717320b888888b81db0a8a35e79f528549f0e9dba13e0e4d6c4c (In short, allowing all unicode characters makes this trivially easy... HN gets rid of some of the unicode weirdness though so I had to put it on Pastebin. I assume this matches the 'load bearing' criteria as I only use variable width spaces rather than additional characters.) Not putting it on the blockchain though because I don't hate the planet.

> I assume this matches the 'load bearing' criteria as I only use variable width spaces I think you might be stretching the rules slightly with that stuff. Using "medium mathematical space" (U205F) instead of an ascii space seems pretty clearly to be using a special character for the purpose of manipulating the hash. I'd much rather amulets be created not by messing with invisible codepoint differences, but rather by making more typographically distinct entries and picking out ones that are correct. When I saw "generated", I thought "have a thesaurus suggest word swaps", not "manipulate invisible unicode characters"

To generate it I manipulated the width of the spaces between the words, changed the grammar and did word swaps :) Looking at the examples provided, they also seem to use line breaks to add further entropy.

Adding data to a blockchain doesn't use extra energy... As in, probably in the order of posting it to HN. The next block will be mined whether or not your amulet is in it. More likely however is that the code you used to generate this amulet was worse for the environment.

  Competing for the oversubscribed resource of space in the next block does drive up the price, though, which in the end also drives up the mining reward and ultimately energy use.
