Crypto bros always open to competition in the marketplace of-- *laughter begins, is only silenced by blocking*

Ever since someone printed out Ron Paul bitnotes, I was wondering, if they are supposed to be exchanged offline, like real cash, how do you know if the bitcoin numbers on them are valid? Are they one-time use only like a scratchcard? How do you know, without scratching it, that there's a bitcoin on it?

They have amazing tamperproof stickers that they got off amazon that were applied by their cousin who doesn't know what a bitcoin is, so as long as the sticker is in place you can trade the notes in confidence!

okay. so Optimism is an L2 blockchain, which as I mentioned in an earlier post, tries to not make transactions in cryptocurrency dogshit slow by completely deferring writing into the main blockchain, (L1) (e.g Ethereum Blockchain, Bitcoin Blockchain) and instead only periodically sending transactions updating the total amounts that are in the L2 blockchain.

the gist of it is.. a gnosis safe is basically a more secured smart contract that allows you to authorize transactions only if multiple people agree to engage a transaction. think of those safes that require two people to turn a key at the same time. if neither key is present or one person refuses to go through with the deal, the smart contract won't authorize it. gnosis safes are basically just more advanced and offers more functionality.

what happened was, the optimism people wanted a private key from wintermute, he told them to use the gnosis safe that was deployed on L1 (ethereum blockchain) thinking they could also access the money on L2 (optimism blockchain). So they transferred it and then realized the mistake that there wasn't a gnosis safe created on L2. While they were trying to figure out what to do to make sure they could access the money.. someone way smarter than them realized wintermute's mistake and took advantage of it by basically creating a new smart contract that looked exactly like the gnosis safe contract, except all the ownership was changed to the hacker's credentials so the hacker now had access to the money in the safe because the hacker's multisig matched wintermute's multisig on L1.

he then took all the money that was in the gnosis safe and transferred it back to L1 using 2 bridges. bridges basically just convert different cryptocurrencies that are on different L2 blockchains. once he got it back on the ethereum blockchain (L1) he washed it in tornado cash (which is a tumbler)

Yes, I know I'm old, get off my fucking lawn so I can yell at these clouds.

So it’s basically a check then, not cash. Only it is set to pay out to whoever the bearer is.

So how does this deal with writing more than you have? Let’s say I’ve got .5 butts in a wallet. Let’s even assume they’re smart enough to not send me more than that in Butt Cash. So I order a stack of .25 Butts worth of Butt Bills and start spending them on things.

But what’s to stop me from withdrawing my .5 butts (or just sending them to another wallet I own) as soon as I get my butt bills? Now when people go to cash that in they’re essentially stuck with bouncing checks.

Like Jesus gently caress they somehow made something that combines the worst parts of cash, checks, and wire transfers.

It’s honestly impressive.

Look at this guy thinking through the ramifications of DeFi more than the DeFi crowd.

It will work like the old days, where you call up the bank to verify funds and hope they don't write more checks between now and then, except your bank is now a terrabyte database.

You give them your butts and they sell you the piece of paper that says you own the butts (you don't own the butts anymore, they do, but they pinky swear they'll give them back to you when you ask). That's what stops you, you already gave them all your money.

The paper butts are connected to their non-blockchain system, so when you give it to someone they have to use their special app to verify the buttcash hasn't already been used

To redeem the bill you have to cut it open to retrieve the secret buttkey (this is actually how it works)

The real question is what is to stop the people who run the decryption server and manufactured the secret buttkey from taking your butts

Dr. Video Games 0031
Jul 17, 2004

technically I don't think they're saying you own the butts, just that whoever holds a butt bill has the right to exchange it for an equivalent value of butts. the idea is that nobody would actually do this but the theoretical possibility of being able to do it is what gives the money its value, like how money used to work on the gold standard. the extremely obvious issue is that bitcoin has no inherent value like gold did. also the company running this is guaranteed to spend/somehow lose its bitcoin reserves and collapse. that, or it's going to be exploited by a hacker for hundreds of millions of dollars. not to mention all the practical issues with having to verify each bill is real and still redeemable every transaction.

Jan 16, 2005
Looking at it closer, it looks like the bill has a thin conductive strip in it which is presumably how it decides whether to send the public key (check balance only) or private key (spend balance). I'm sure there is no possible way to tamper with this high tech system

So to put it in human terms, the company made a deal to hand over a bunch of money but fat fingered the address (same street number, same street name, wrong city), the delivery got sent there, and nobody involved was around to get it returned but sort of assumed it would be fine until they figured out a fix. The hacker found out, got to the place where the money was sent, and then dropped a building into that spot that looked legit enough to fool the delivery folks into handing it over, and then took it all and immediately put it through a "I just stole a bunch of money, make it seem legit" machine.

Is that about right?

to explain the optimism scenario (most of it) in a different way: it's still stupidly complicated.

Ethereum (L1) has sidechains (L2s) that are an equivalent of another spoken language aka technical blockchain. So you can send to the same address on an L2, but only on a normal wallet can you interact on that L2. But they exist separately and basically you have to bridge poo poo back and forth, you can't just use L2 assets on an L1 and vice versa as it only exists on one or the other or as a wrapped equivalent.

The way these multisig wallets work (where the gently caress up happens) is it's fancy code that only works on the L1 or only the L2 it's made for. You cannot just send ether (L1) to the L2 wallet, the L2 wallet won't interact with it.

Wintermute, a crypto multimillion dollar market making business, never checked that when they sent two test transactions a token across they could actually access it. By the time they figured out how to reverse the transaction and re-send the tokens so they could access the tokens, someone else already did and then it became the standard "welcome to blockchain get hosed" that immutable blockchains are well known for. It was all done through a privacy mixer so that cash is gone forever. Wintermute put up 50 mil to make up for the 20 lost +, requested another 20 to complete the work, but that's telling enough on its own. Hopefully this will be the end of wintermute.

Even if someone came up with a clever standardised solution where models and textures could be reliably auto converted from engine to engine, model to model, and artstyle to artstyle, it's still going to run into the same problem as NFTs, namely that I could just download the data in question and use it as I see fit, without having to touch a blockchain at any point and without owning the NFT for said data.
