2381  Bitcoin / Bitcoin Discussion / Re: On Ordinals: Where do you stand? on: March 06, 2023, 05:27:17 AM
you would think the devs would understand that point of view and do something about it. why did the witness need to be so big anyway?
Historically the bitcoin consensus rules about things that aren't checked have been loose (they still are) for example your output script can be literary anything like an invalid script or any arbitrary data of any size like a picture that is not even a script.
This is a good thing because it allows future expansion through soft forks but also it could lead to abuse of the system and spam attacks.

historically pre 2017 there was only ONE opcode that allowed things unchecked
it was called "anyonecanspend" but even that had a byte limit

it was the 2017 events that opened that up
There has never been any OP codes called "anyonecanspend" ever in Bitcoin.

You can easily check what I said above on regtest or testnet, as I said your output script (ie. scriptpub) is NOT checked so you can dump anything WITHOUT using any OP codes in there with any size (of course smaller than block size).
The ONLY thing preventing you from doing it is the standard rules where nodes don't relay your "valid" but spamy transaction.

That was cute Cheesy

US Government own atleast 15 Million BTC
Wrong, US government owns 30 million BTC Cheesy

How US Government created 15M wallet? creating BTC wallet is very easy, you can create btc wallet with 1 click only, to make 15M wallet you need 15M click which can be done by an automation bot or just a few code.
You are wrong again, US government clicked 30 million times to create 30 million wallets to store 30 million bitcoin Cheesy
He changed his mouth 3 million times to make 30 million clicks.
2383  Bitcoin / Development & Technical Discussion / Re: REWARD offered for hash collisions for SHA1, SHA256, RIPEMD160 and other on: March 06, 2023, 04:22:57 AM
Can someone please explain what happens if there is a collision? How can someone exploit it?
I can only think of weird ways of abusing the scripts but they all involve you stealing your own coins which make no sense. That is because in a collision you have to create two different messages that produce the same hash, the hash that would be used in a pay to script script meaning you are creating the output script yourself.

Quote
How can we stop the exploit?
By changing the hash algorithms that are used, for example by switching to version 3 of SHA.

Quote
Is it safe to publish such collisions like what the OP is asking?
If you publish the collision, anybody would be able to spend the reward of these puzzles. That's about it.

Quote
Btw, why bitcoin's SHA256 is different, is it because it hashes bytes?
The only difference is the size and the algorithm, otherwise all hash functions deal with bytes although the algorithm is defined to work with octet strings, they are all implement to deal with full octets (ie. the algorithm is defined to let you compute the hash of a 1 bit input but implementations don't let you and it has to be padded to 8 bits).
2384  Bitcoin / Development & Technical Discussion / Re: NFTs in the Bitcoin blockchain - Ordinal Theory on: March 06, 2023, 04:04:42 AM
No, we should call on nodes to reject spam transactions that are abusing the system and never relay such transactions.
These are transactions that miners *want* to include because they still pay competitive feerates.

So users will find a way to relay them directly to willing miners (as ordinals.com already does), and if not relayed normally, the mempool will show a distorted view of the fee market.

You're trying to fight basic economics in a permission-less system.
I'm not trying to fight anything, this IS how we have been fighting spam all along. The same arguments you made about miners being able to include non-standard transactions could have been made about literary any other form of injecting garbage into the blockchain (eg. placing ~1 MB garbage entirely in your scriptpub).

Quote
Bitcoin is by design a transaction storage system, since the entire tx history must be verifiable.
Bitcoin also cannot effectively distinguish between financial scripts and data storage scripts (note that a less efficient data storage in fake P2PK outputs is possible as well).
You can't distinguish among the standard scripts that contain the garbage but you can easily distinguish it when they are doing something non-standard. In case of the Ordinals Attack things are actually too obvious to distinguish.

Hang on, isn't witness data completely free coz core decided it should be, when they implemented segwit, and thus punish people using '1' addresses?

So if these super large NFTs are in the segwit witness data, then they don't cost anything extra for the transaction?
Witness parts of transaction contribute less to the transaction weight, hence they are cheaper not "completely free".
To be honest I'm not sure if you are trolling since it is very surprising to see one of the oldest forum members and the owner of one of the oldest mining pools has no idea how Bitcoin works!
2385  Economy / Economics / Re: War: who benefits and how! on: March 05, 2023, 03:44:36 PM
I want to ask are there beneficiaries to this war and in what ways are they benefiting from it.
It depends on the scale of the war, the region and how many or who is involved in the direct armed conflict. The chaos large scale wars like the two European Wars also known as World Wars 1 and 2 create benefit those who stay far away from that chaos like United States. In WW2 for example, US benefited the most since it was far away and wasn't impacted as much as say Europe itself which then led to giving US tremendous amount of power which they abused in the past 80 years.

The Russian-NATO war is a medium scale war at best since it is focused in one small area of the world and the impacts are different depending on the distance and involved in the actual conflict for each country.
For example US like the WW2 is benefiting the most since they could successfully rescue their failing economy for the time being by creating more market for their exports (eg. LNG to Europe or the massive increase in weapons sale) that couldn't have existed without this war.
Other countries like Europe (different countries in the region with different degrees but all the same) are negatively impacted since they are being abused by US (ie. selling much more expensive LNG to Europe instead of the super cheap Russian gas they used to receive) so the impact is huge and negative. Like the ongoing deindustrialization in Europe.

Other countries that are also far from this conflict are seeing a range of different effects depending on their involvement and level of independence. For example a country that lacks independence like Japan is being forced into suffering negative economical impacts while countries with more independence like China are taking advantage of this situation and are expanding their economy (China is actually reporting high growths these days!) by having access to cheaper energy, taking over markets that were left by Europeans, attracting investment and industries that left regions like Europe, etc.

With the rest of the countries being in between like Turkey, India, etc. that are experiencing both negative and positive impacts. Like Turkey taking advantage of the chaos to seek benefits geopolitically speaking.

That's just a summary though, your question can't be answered any better due to the broad nature of it. It is best to analyze the situation per country not as a whole. For example even in a region like Europe there are major differences between each country like Italy seeing a different impact than France for instance and they are both different from a country like Latvia in Eastern Europe.

No, he is making a statement against LNURL. As I pointed out above, he isn't actually pro-censorship.
That's how it starts. They don't go all the way from the start. Gavin wasn't nuts in 2010, he slowly went crazy, visited CIA office, started proposing weird things for bitcoin, abandoned bitcoin development and eventually claimed the obvious scammer CSW is the real Satoshi! Smiley

As I said above, it seems like core devs go nuts after some time. Another case is Mike Hearn who dumped all his bitcoin and said "bitcoin has failed and is dead" back in 2016. lol
2387  Bitcoin / Development & Technical Discussion / Re: NFTs in the Bitcoin blockchain - Ordinal Theory on: March 05, 2023, 02:50:23 PM
Are you proposing that the community should call on the miners to censor those transactions? That would be against the philosophy Bitcoin was built on.
No, we should call on nodes to reject spam transactions that are abusing the system and never relay such transactions. This is in accordance with the principles of bitcoin, the peer-to-peer electronic cash system and is against the principles of bitcoin, the permit anything file storage system.
2388  Other / Beginners & Help / Re: Misinformation about crypto (bitcoin). on: March 05, 2023, 05:26:51 AM
Apart from the massive amount of FUD that is out there about Bitcoin, sometimes the people who tell others about bitcoin are doing a terrible job. For example back in 2012-2013 someone introduced bitcoin to me by telling me something like "you get paid by using your PC to solve mathematical equations". Obviously I thought that is a dumb thing and logically I ignored bitcoin altogether until about 2 years later in 2014 where I was introduced to bitcoin again but this time as a "censorship resistant currency that you can use without needing any middle man" and obviously I was hooked right away regretting the lost couple of years.

Nowadays things are the same still. There are people who introduce bitcoin as a lot of weird things like as a "profit making" tool which you invest in! This is obviously one of the reasons the adoption is this slow.
This is also why I have always tried to introduce Bitcoin to others as a currency not an investment or something you mine, etc.

This is a good thing because it allows future expansion through soft forks but also it could lead to abuse of the system and spam attacks.

Over the years to prevent such abuse (eg. placing arbitrary junk in your scriptpub) more and more standard rules were introduced where the nodes rejected such non-standard transactions from their mempool and refused to relay them hence it successfully prevented spam.

When it comes to SegWit, the rules are flexible in many places that allows future expansions but only some of them were prevented as non-standard while others fell through the cracks and helped creation of attacks such as Ordinals.
2390  Bitcoin / Bitcoin Discussion / Re: Mempool full? Long transaction times + fees x10! on: March 05, 2023, 04:51:43 AM
The fee market only works for normal spam attack types but not with a incentivized spam attack. Ordinals is the later and the bigger it gets and the bigger market that it gains the bigger the spam is going to get because people who are gambling with these shittokens don't care about paying a higher fee.
Exactly like what the exchanges do, a gambler trading shittokens on CEX doesn't care much about paying a high withdrawal fee.
2391  Bitcoin / Development & Technical Discussion / Re: Questions about soft fork on: March 05, 2023, 04:12:39 AM
Jihan Wu and his friends from the mining cartel
They actually created the shitcoin called bcash using the same principles of BIP148, it was even called MASF (mocking the UASF thing). That is a minority group creating a fork disregarding the rest of the network (including miners' votes).

The miners don't speak for the whole network. If it did, then the network is centralized towards the Mining Cartel.
I never said they do anywhere! But you can't deny that miners are an important part of the network and attacks like BIP148 are completely ignoring/eliminating miners.
2392  Bitcoin / Bitcoin Discussion / Re: Matt Corallo advocating for censorship on: March 05, 2023, 04:04:46 AM
I don't know exactly, how to run a node with tor?
Here is a guide: https://en.bitcoin.it/wiki/Setting_up_a_Tor_hidden_service

But you don't need to do that as I said if the US regime decides to place such restrictions, those running the nodes in US would be at risk not the rest of the world. Keep in mind that it would be trivial to get these nodes to relay certain transactions that would get them shut down by US authorities and the node operators arrested. So they either have to try so hard to hide or stop running nodes altogether.
2393  Economy / Economics / Re: The impact of Russian and Ukrain war on world economy on: March 04, 2023, 05:08:35 PM
I am not sure how accurate this is. From social media, I get an impression that mercenaries who are fighting on the Ukrainian side (mostly Poles and Americans) have dwindled significantly during the past few months. Only the "Georgian Legion" remains active in the frontline cities. And I am yet to find any reports about large-scale activity from the Syrian mercenaries.
The presence of Takfiri terrorists (who aren't all Syrian even though they're transferred from there) can be verified from 3 sources:
1. The eye witnesses in Syria seeing the transfer of these troops usually with the help of Turkey and US over the past year to Ukraine. And the fact that their numbers in places like Idlib has decreased.
2. The videos showing them inside Ukraine fighting on Ukraine's side even among the high ranks
3. The methods of fighting that is being used like the Urban Warfare which these terrorists have a lot of experience in because of what they did to Syria, or like using quadcopters to drop grenades on foot soldiers which has ISIL written all over it.

But I agree that the number of them and what percentage they have in armed forces of Ukraine is disputable considering there isn't any reliable stats out there yet.
2394  Bitcoin / Bitcoin Discussion / Re: Matt Corallo advocating for censorship on: March 04, 2023, 04:48:52 PM
The thing is; if there isn't enough people that care, and kick up a fuss it'll likely lead to this. I don't know if the government would be threatened enough or if they'd just prefer to regulate Bitcoin so that they can profit from people using it, but tighter restrictions will likely be put in place around the majority of the world. Mainly, for them to profit from it.
I doubt the number of people "resisting" really matters to oppressive regimes. If their perceived threat is big enough, they won't hesitate. There are already certain sanctions US government has in place involving bitcoin such as the list of bitcoin addresses that OFAC has placed under sanctions lol.
The only reason they aren't (or better say can't) enforce it is because bitcoin is decentralized so they have little to no power here. They may only put some pressure on domestic centralized exchanges.
2395  Bitcoin / Bitcoin Discussion / Re: Mempool full? Long transaction times + fees x10! on: March 04, 2023, 03:25:22 PM
Anyone can link me to a reliable site that shows the median, cheapest high priority fee (not just the median fee or sats/vByte), ideally in BTC and in USD? I can't see such option in the links posted above.
The https://mempool.space/ has been doing a pretty good job with a simple understandable UI. It has the values in both satoshi and dollar.


There is also https://jochen-hoenicke.de/queue/#BTC,24h,weight which is a very old tool to visualize the mempool and see the total size for each fee level. But it is not the most user friendly.
And of course there are wallets such as Electrum that also do a pretty good job at giving the user a good fee estimation.
2396  Bitcoin / Bitcoin Discussion / Re: On Ordinals: Where do you stand? on: March 04, 2023, 03:18:31 PM
does anyone know why this person keeps uploading tons of the same image?
Maybe they are trying to prove there is no "uniqueness" despite what the attackers are advertising The Ordinals Attack as.

it would be nice if bitcoin had a feature where someone could do another transaction with a higher amount to remove someone else's junk from the blockchain.
That is similar to basically what the fee market does. Nodes all have a finite amount of memory to keep unconfirmed transactions in, when they surpass their limit they start dropping transactions with lowest fee.
Although you don't remove the junk from blockchain, just the mempool and until they rebroadcast the same junk or the junk with higher fee.
2397  Bitcoin / Bitcoin Discussion / Re: Matt Corallo advocating for censorship on: March 04, 2023, 03:02:15 PM
If someone is living in a dictatorship that would fine or jail people for running a bitcoin/LN node then maybe they should be the ones running their node through TOR or stop using bitcoin altogether. The number of countries US has sanctioned is far higher than just 5 and things are going to get worse the weaker US dollar gets specially as bitcoin adoption grows globally while more countries join the "dedollarization" bandwagon.

In any case, is it just me or do core devs/contributors go nuts after a while to the point that they even go against the very basic principles of Bitcoin? There certainly is a pattern here with Andresen as its pioneer. What the hell is happening behind the scenes to these guys Cheesy
Has "someone" with a 3 letter name been targeting them?
2398  Bitcoin / Development & Technical Discussion / Re: NFTs in the Bitcoin blockchain - Ordinal Theory on: March 04, 2023, 04:29:24 AM
Because Bitcoin is permssionless and censorship-resistant, I believe not all who uses the Bitcoin blockchain as a "cloud-storage" is attacking the network, ALTHOUGH Ordinals could open attack vectors for bad actors to congest the network, drive fees higher, while also being incentivized to do it to continue doing it.
Wrong.
First of all not letting people abuse this payment system that is supposed to handle money transfers is not against censorship-resistance or permissionlessness of bitcoin. In fact it is enforcing them. You see these concepts doesn't mean you should allow people to do whatever they want. Rejecting such attack transactions is also not new, there are dozens of tx types that we are rejecting. In order to keep the integrity of the system we need to do that.

It also doesn't need malicious actors to spam the network, the spam would take place naturally and ruin bitcoin as a payment system. Don't forget that it wasn't malicious people who used cryptokitties or buy any other shittoken on shitplatforms like ethereum!

2400  Economy / Economics / Re: The impact of Russian and Ukrain war on world economy on: March 03, 2023, 10:00:21 AM
The war is definitely shifting away from Eastern Ukraine as it is evident from the withdrawal from Bakhmut and the transfer of forces to South West. I try not to predict what's going to happen since the information coming out from this war is usually manipulated and is more of a propaganda from both sides.

The Americans have been asking Zelensky to withdraw from Bakhmut for many weeks now. But he is adamant that he can reconquer all the lost regions. Ukraine has enough manpower to sustain the war for another 3-4 years. They are a country of close to 40 million people (after subtracting those who are residing in areas controlled by Russia). 1,000 KIA per day would mean 1 million losses in 3 years. It is something they can afford at least theoretically. But I am not sure whether the NATO would be interested in prolonging the conflict for so long. NATO weapon supplies are not infinite, and in due time there will be growing opposition to the spending on this war.
The bulk of Armed Forces of Ukraine is no longer Ukrainian at this point, it consists of some "unofficial" NATO troops and takfiri terrorists transferred from Syria to fight Russia. Besides, a large part of Ukraine population has already fled the country. Considering how they've shown to fight for a decade in Syria, I agree that Ukraine can keep it up against Russia.

You are right about NATO (more specifically Europe) not being able to afford this war for that long but US is calling the shots, not Europe, nor Zelensky specially since he is just a pawn. And US doesn't want this war to end this soon or the benefits of it would stop too.
So the real question is how much longer Europe can withstand de-industrialization and how much longer they can violently suppress the mass economical and anti-NATO protests before they change their position.
