caird coinheringaahing

@RedwolfPrograms Seems flawed as a premise. One of the best things about the internet is how much more free information became, and NFTs seem like a flawed attempt to constrict that

Redwolf Programs

What a lot of people don't seem to understand is that NFTs, like the rest of cryptocurrency stuff, is only a decentralized register

caird coinheringaahing

Like, sure, technically, you own the rights to a bit of data (e.g. an image), but unless you can enforce that ownership, its essentially meaningless

Redwolf Programs

12:02 AM

So it doesn't make any information harder to find, it just provides a decentralized way to decide who owns something

Yeah lol

user

Oh, it seems like they're Bitcoin but unique and they're more like art than currency

Redwolf Programs

Yeah

user

So, basically useless

Redwolf Programs

They don't have to be art though, the NF part stands for "non-fungible" meaning it can be literally anything that isn't money

user

Here I was hoping the non-fungible part meant something cool like never getting fungus or something :P

@RedwolfPrograms Sure, but if it isn't money and depends on what other people think of it, then it's like art

Perhaps "collector's item" would be a better phrase than "art"

Redwolf Programs

12:04 AM

Well they don't have to be images, is what I mean

user

NFTs that aren't monke sound even more useless :P

caird coinheringaahing

E.g., if you own the Mona Lisa, sure, you can say that you own it. You can hide it away in a museum and charge people to look at it, and do what you want with it. But, if you let someone into the museum and copy it to such degree where no-one can tell (or really wants to tell) the difference, then you can't decide what they do with that copy. The entire point of NFTs comes from being able to display them on the internet, which has such inherent freedom of info that you can't charge entry

Redwolf Programs

Yeah, blockchain really is just a solution looking for a problem

user

idk, I honestly can't make sound decisions about this based on a 2-minute reading from Wikipedia and the titles of Reddit posts, and I'm too lazy to actually read up on what they are, so disregard everything I've said above about NFTs

@RedwolfPrograms git

Redwolf Programs

Git?

user

12:06 AM

That sounds like a legit use of blockchain (well, blockchain-like tech)

Redwolf Programs

Git's not blockchain

user

Yeah

@RedwolfPrograms Also I feel like I've heard this joke before lol

Redwolf Programs

It's a pretty common sentiment

I don't even think it's the best option for a decentralized currency, let alone proving ownership of physical objects or managing voting systems

user

If mining crypto didn't waste so much money, I don't think it'd be that bad

Redwolf Programs

Not just money, massive environmental damage

user

12:08 AM

I meant to say energy lol, but that too

@RedwolfPrograms Do we even need a fully decentralized currency? It's perfectly acceptable to have a few trusted organizations, as long as there's enough of them and regulations and stuff

Redwolf Programs

Bitcoin as a whole is basically a giant space heater the size of Belgium

user

Feels like the bubble will burst at some point; I just hope the fallout isn't too big

Redwolf Programs

We're putting 0.5% of our global energy production into warehouses of ASICS

user

caird coinheringaahing

Redwolf Programs

user

@cairdcoinheringaahing You can never be 100% sure, but you can set up laws and agencies that investigate these organizations

You can't trust the government 100%, but you can trust that they probably won't steal your money outright

Redwolf Programs

All Bitcoin offers is a way to pay for illegal activities without getting COVID from handling physical cash

I maintain that it will never be a better option than any non-blockchain solutions

I also dislike it solely for the fact that if you say "I'm interested in crypto", people think you're talking about cryptocurrency and not cryptography

user

I'm interested in crypto

caird coinheringaahing

I'm interested in crypto, cause if I can decrypt my exam password, I can see them early :P

Redwolf Programs

We could power 1.3 million homes with the amount of electricity cryptocurrency turns directly into heat

user

12:19 AM

Where do people even get all this electricity? Are there just that many people mining Bitcoin?

Redwolf Programs

Yep

emanresu A

Partially people who are trying to stop China from taking over bitcoin

(If they get more than 30% or so they can control it for some reason I forgot)

lyxal

@RedwolfPrograms I've considered actually making NFTs just to see how profitable it really is for ordinary people

user

Does it really matter lol

caird coinheringaahing

That seems.... off. The entire point of a decentralised system is that its very hard for one single party to control it

Redwolf Programs

12:21 AM

Well because if you have enough computers, you can "prove" anything through Proof Of Work (which is what bitcoin uses)

user

If people from other countries stop caring about Bitcoin, its value will fall, right?

@cairdcoinheringaahing I think by "control" emanresu just means "own lots of Bitcoins"

Redwolf Programs

Nope

caird coinheringaahing

> If people ~~from other countries~~ stop caring about ~~Bitcoin~~ money, its value will fall, right?

That's literally how all money works

Redwolf Programs

If you have a certain percentage of the computers doing the mining, you can literally make all of the money yours

Because you control the blockchain

caird coinheringaahing

Isn't a 51% attack the only real way to control a decentralised system?

Redwolf Programs

12:22 AM

Yeah, it's basically a 51% attack but with less than 51%

user

@RedwolfPrograms Would it even matter if people stop accepting Bitcoin and want other currencies instead?

I could create my own cryptocurrency called "dogebadcoin" and own 100% of it but that won't help me at all because no one else would use it :P

Redwolf Programs

@user I guess not, but if there's billions invested in btc and all of that's suddenly gone, that's bound to have some negative effects

emanresu A

@RedwolfPrograms Yeah, except someone said 30% is enough for bitcoin

[citation needed]

caird coinheringaahing

@RedwolfPrograms depends on who owns the billions :P

Redwolf Programs

Well as user said, it'd totally devalue it

caird coinheringaahing

12:24 AM

If Tesla Stock drops to 0, and Elon Musk suddenly is worth less than me, I don't see a negative effect :P

user

@RedwolfPrograms True, although it probably wouldn't happen immediately

Redwolf Programs

I'm not so sure about that

user

In which case China might be Supreme Lord of Bitcoin for a while, but not for too long, so ¯\_(ツ)_/¯

Redwolf Programs

Everyone would notice pretty quickly if their wallet just became instantly empty

And they'd probably not decide "hey, I should pay more IRL money to get that back"

user

Wait why would people's wallets become empty?

Redwolf Programs

12:27 AM

Well if they took it all for themselves

user

They'd still have their Bitcoin, it'd just not be worth that much (and surely they'd see it dropping in the news)

Redwolf Programs

Presumably that's what you'd do if you had total control over the blockchain

user

@RedwolfPrograms Oh like if China just got a million computers and computed their way to controlling everything

caird coinheringaahing

Why? If you do that, it becomes worthless

Redwolf Programs

You can change the ledger to show any transaction

user

12:27 AM

^^

Redwolf Programs

Hmm true, I guess you could be a bit more strategic

user

caird has a point, if no one else owns Bitcoin, then no one's going to care about it

caird coinheringaahing

If you take everyone's bitcoin, no one will value any bitcoin

user

They'll just switch to Ethereum or whatever or drop out of crypto entirely

This is why we need to peg our currency to cocoa beans :P

Redwolf Programs

Although since it's public, people would realize what was happening within minutes if enough bitcoin was being mined/stolen for it to be worthwhile

user

12:28 AM

Yup, it'd make the headlines given how big a thing Bitcoin and crypto are

caird coinheringaahing

Redwolf Programs

@cairdcoinheringaahing Did you look at the ASCII art part though?

@RedwolfPrograms I think validating ASCII art could potentially lead to interesting solutions

caird coinheringaahing

If you need to drink water, just put an ice cube in your whiskey :P

Redwolf Programs

@user But would any solutions actually validate the ASCII art rather than the numbers?

I think this could actually be a lot more interesting in reverse, where you're given ASCII art of a number and have to figure out if it's a square number

Redwolf Programs

2:17 AM

Honestly after having given it some thought, I think a centralized, but cryptography-based, currency is a much better option than a decentralized one

Because here's the important part: with signatures and a counter, it's impossible for the centralized authority to fake transactions or delete them. All they can do, worst case scenario, is silently ignore incoming requests to add transactions to the list.

discussion youtube easter-eggs

Redwolf Programs

And if you get rid of the decentralization, you get rid of a massive amount of complexity and potential for abuse

And you can still make it semi-decentralized, by having a couple of different semi-trusted but distinct organizations, though that adds in a little bit of complexity and a small but not that important 51% issue (since, once again, the worst you can do with a 51% attack in this system would be silently dropping transactions people request to occur)

emanresu A

Why not something where the centralization authority changes hourly?

Redwolf Programs

Because then everyone gets their own chance to be an asshole, instead of it being a collaborative effort

You could have, e.g., a central authority in the US, one in Britain, one in Russia, one in China, and one in somewhere like Switzerland, and chances are you'd never have three of those authorities trying to block you from doing a transaction at once

And anybody could run their own server that just checks every authority's list, and computes the consensus. It's a much simpler system without the complexity required to be able to support an arbitrary number of "authorities"

emanresu A

Although... this is starting to sound decentralised.

Redwolf Programs

2:28 AM

It's semi-centralized

You have a known number of central authorities, with the power distributed among them

So you don't need to worry about all the complexity of Proof of Work or Proof of Stake, because you don't need the concepts of mining or blocks

And there'd be much smaller fees, if they existed at all

Riolku

Alright i've been summoned by hyperneutrino and the word "crypto"

I think you might be right

Have a handful of large organizations controlling the currency

I suppose it's worth noting that this system is liable to be just... meddled with so fees are high

and coins aren't generated from anywhere

like when you have a few authorities if they collaborate they can do whatever they like, and I think that's exactly what bitcoin avoids

I don't like bitcoin though, because the power consumption is ridiculous

but I think there are definitely some things there that are nice that we can't get otherwise

in some ways this isn't different than the system we have now with banks

Wezl - a cautionary tale

2:46 AM

rats, I found a really good challenge but I can't upvote it >:|

emanresu A

You already used up your vote cap?

Wezl - a cautionary tale

no it's just that you generally can't upvote the best questions

It's like they think self-esteem is a bad quality

Redwolf Programs

@Riolku Well there's signatures still, so they can't decide to fake transactions

All they could do to mess with things, even if they all collaborated, is prevent some or all people from adding transactions to the ledger

The way I'd see it working is the two parties would sign the details of the transaction along with some transaction ID (to prevent replay attacks), and then send a copy to three or four of the central authorities. They'd all add it to their ledgers, alongside a hash with an incrementing counter for that authority (also to prevent replay attacks), and as long as at least three agree at some point that transaction occured, it would be added to the ledger.

Riolku

3:03 AM

and there's still anonymity

it's pretty interesting

because we still have anonymity and prevention of forgery

Redwolf Programs

I'm not entirely sure how adding more currency would work, but maybe a lottery type thing weighted by stake

(For generating random numbers to use in the lottery, each of the authorities could choose a random string, and then they'd all be publically announced and hashed to create the final random number)

user

We add more cryptocurrency depending on cocoa bean production

Redwolf Programs

Is user a lobbyist for the chocolate industry? :p

user

By doing this, we can ensure there isn’t too much inflation

@RedwolfPrograms I would like to be :p

It’s easy: our currency must be based on societal values. And what we value is chocolate. So if you produce more cocoa beans, you get more monies. Simple

Whereas by instituting a lottery, what message are we putting out? That we like gambling, chance. No! It’s time to return to our traditional values of hoarding money and chocolate

Redwolf Programs

Ooh, I've got it! Maybe a small transaction fee would be charged, and that would be evenly distributed according to stake

And perhaps a multiplier applied

So like, if the total volume of transactions results in $1M in fees, maybe 1% or something would be added on top (how new money enters the system), and then that would be distributed to everyone

It'd be cool if there was something like less active accounts getting a smaller share of it, so that people can't just build up a massive amount of money by sitting there with a small initial investment from early on, but that'd likely just encourage everyone to set up a bot to transfer between a few dozen accounts every couple of days (wait no, transaction fees are thing! maybe this could work...)

Because you wouldn't want a Satoshi Nakamoto type thing where someone gets a bunch early on and then disappears for a while, slowly building up billions of dollars

And there's no reason consensus should require 3/5 here either...since the central authorities can't fake transactions anyway, 2/5 or even 1/5 would work just as well and be significantly harder for a rogue authority to abuse

12:38 PM

hmm

sort of a mix of a heavier right and the bottom bit not being actually connected but if that's it then it should look fine at a smaller font size

lyxal

ngl looks like the preview don't match the actual

Adám

@lyxal There's no preview. The t on the top is a reference glyph.

lyxal

that's a horrible reference t

Adám

@PyGamer0 remove one pixel from the left side of the cross-bar.

PyGamer0

ok

that looks wayy better

12:42 PM

oh wow yeah that's so much better

PyGamer0

guess the font name :P

Wezl - a cautionary tale

1:25 PM

can I give a suggestion?

PyGamer0

yeah go ahead

the current name is bad

@pxeger I do also believe it was just a misunderstanding of some sort / misspoken but you would not believe how offended I felt when I first saw "this is off topic" haha

im over it though im not mad no hard feelings etc ^_^

but yea im still brainstorming how to turn the concept into a more interesting challenge

Adám

I think it is fine, if simple.

thejonymyster

right i dont mind it being simple because i personally want to see it get really really small with clever thinking in multiple languages

but popular opinion is that there should be a bit more meat to it, so i dunno

Adám

Are we allowed to restrict the input domain, to say strings or characters or numbers?

thejonymyster

that seems like itd break the challenge actually

Adám

I'm not saying we should be allowed to, but the spec should mention it.

thejonymyster

1:45 PM

true! hm

Adám

It'd be quite simple in APL: 0 1∊⍨⊂

(This is without limiting allowed inputs.)

Wheat Wizard

And what counts as limiting the set of possible inputs?

thejonymyster

right yea "if its a member of this group output this value of the group, else output the other value of this group" as a literal translation of the challenge

Wheat Wizard

I mean probably a program is not going to be able to take an error thunk as input.

thejonymyster

error thunk? i cant tell if thats a typo or a concept i do not know

Adám

1:47 PM

The idea would be the input as predicate.

Wheat Wizard

@thejonymyster It's data that when evaluated instantly causes an error.

thejonymyster

ah that makes sense

@Adám what does this mean? (asking as noob)

Wheat Wizard

For example if you lazily evaluate 1/0 it's thunk and can be dealt with, but if you inspect it it errors.

Adám

{0::0⋄⍵:1} in APL where {0::0 catches any error and returns 0. ⋄ (then) ⍵: if the argument (only 0 and 1 are valid Booleans), 1 then return 1.

(This is an invalid solution, btw. but brought here to illustrate the concept).

thejonymyster

oh like, evaluating the input to determine whether to accept or reject it rather than just normally reading it?

Adám

1:51 PM

Yeah.

thejonymyster

:D i learn

Wheat Wizard

It's probably at the very least only possible in untyped or very close to untyped languages.

PyGamer0

@Wezl-acautionarytale ... (i am waiting)

Wheat Wizard

It's also does get into questions of what it means to be equal to something else.

PyGamer0

@WheatWizard is your pfp from a game?

Wezl - a cautionary tale

1:53 PM

@PyGamer0 oh sorry. I was just going to say that the j's curve is smaller than the r's curve, and I think it would look more consistent if they were the same

thejonymyster

@PyGamer0 it appears to be a photograph, so i doubt it. see for yourself though i.stack.imgur.com/ZEfmj.png?s=128&g=1?

Wheat Wizard

@PyGamer0 No it's Norsola Johnson, the cellist for Godspeed You! Black Emperor from their 2002-03-13 concert.

thejonymyster

oh hell yea

do they still tour i wanna see them live at some point

PyGamer0

lol it looks like some video game character on a horse holding a bow

Wheat Wizard

They just cancelled their European tour.

I had tickets to see them in Koeln.
