Pretty crazy that the US government hates Elon so much that they wouldn’t subsidize Starlink for Ukraine. This just makes Elon look better in my opinion, as he was the bigger man even while Ukrainian politicians call him names and our own government won’t even mention his company’s name. I’m glad Elon is on the side of common sense. Seeing people hate on him really shows that it doesn’t matter how awesome and successful you are. Someone will always complain.
I think it is more the Biden administration and mainstream democrats that hate Musk.

Musk is very pro-freedom, and authoritarians do not like that. His buying Twitter, and promising to make it more transparent and more free-speech-focused isn't helping his cause.

Space X is not a charity, it is a for-profit business. With all the billions of dollars worth of military equipment going to Ukraine, paid for the US taxpayer, it is not unreasonable to expect the US government to help pay the bill for Starlink. They are paying for everything else.
102  Bitcoin / Hardware wallets / Re: AirGapped Hardware Wallets on: October 23, 2022, 08:28:45 PM
Some argue that Jade is not really airgapped because of connection with Blockstream server, but that is debatable.
Data from the internet must interact with the Jade device. I have previously argued that some HW wallets are superior in security compared to "traditional" 'air gapped' setups.

Every security measure uses various tradeoffs. The Jade, for example, reduces the risk of loss (via theft) if someone gains physical access to the device, in exchange for incremental additional vulnerability via having to connect (via an app) to the internet. Realistically, I think the risk of having a HW device stolen is greater than someone being able to inject malware into it, so it is probably a good tradeoff. However, I don't see how one could argue that Jade is in fact "air-gapped"

This was an average round this time.
Looking at the timing, @ddmrddmr said that it took him "just over 3 minutes", while in my computations it was "just under 3 minutes".

Most likely, the discrepancy has to do with the time ddmrddmr spends running his script that does not involve the actual sending of merit. For example, querying his DB to find the posts he wants to merit, logging into the forum, and accessing the first page to merit the first post in his spree.

Yeah probably this is a reasonable explanation.
Actually 3 seconds for all these operations look a lot to me, but I really I have no clue about how long does all these operations take.


Logging into the forum and accessing the first page to send merit should take 1 second each. The reason for this is that it is good practice to limit the rate you access pages via automation to one per second, which is a rate that Theymos has previously requested that members limit their scripts to.

Querying his db will take some non-zero amount of time.

Critics even say that the British economy took a nosedive as her policies where deemed poor and unessential.
She was in office for only about 6 weeks, and her policy proposals had not yet been voted on, let alone implemented.

IMO, it is more likely that markets were responding to the potential for a winter energy crisis that was caused by her predecessors, and Job Biden.

Conservatives should not have signed on with blowing out the budget over COVID lockdowns that had little to no returns.
This.
106  Bitcoin / Development & Technical Discussion / Re: What is the lowest (non-zero) transaction fee you have ever used or seen? on: October 21, 2022, 06:49:12 AM
I think pools will eventually start selling their block space (off chain) to large consumers of blocks space (for example to exchanges) via long term deals. Today, pools sell their block space (off chain) to retail consumers, often at a huge markup, however the required tx fee is currently so low, that most likely, few need to do this.
This makes no financial sense at all. For both the mining pool and the buyers.
If the pool is selling the space at a higher price that means the buyer is basically paying a higher fee. In other words they could just pay a higher on-chain fee in first place. If they are selling it at a lower price that means they are losing revenue which again makes no sense.
There is no shortage of demand for the block space either for the pools to need to do some marketing and ensure their revenue.
The sale of block space at a premium to 'retail' customers when fees are high makes sense because many lack the technical skills to double-spend a transaction to increase the fee. The high fee is really more for technical help than for including the tx in a block.

Pools could sell block space well into the future to companies who expect to need a lot of block space in the future. This will allow both the pool and the consumer of block space to have a more predictable revenue and expenses. Today, transaction fees to get transactions confirmed, even on a next-block basis is very close to zero, but this will not always be the case.
107  Bitcoin / Development & Technical Discussion / Re: What is the lowest (non-zero) transaction fee you have ever used or seen? on: October 21, 2022, 04:04:16 AM
Most clients will only allow users to set a fee rate when crafting a transaction, however, it is possible to craft a transaction with a 'flat' fee, for example, x sats. Or in the case of what j2002ba2 found, 1 sat.

Regardless of what nodes will relay, as long as the transaction is valid, if a pool is willing to include said transaction in its found block, it has the potential to be confirmed, if the pool is aware of the transaction. Most of the time, this will involve either the pool receiving compensation for including said transaction(s) off-chain, or the pool including its own transaction(s) in its found blocks.

You are correct and since OP didn't ask more clearly, it is a very good answer.
However, unless one has his own pool, this doesn't worth the hassle, so it has only an "academic value". Still, nice catch!

108  Bitcoin / Development & Technical Discussion / Re: Can we further reduce the size of the blockchain by storing only tx hashes? on: October 20, 2022, 07:00:13 PM
Nodes can already disregard blocks that are more than x blocks deep. All that these nodes need to store is the UTXO set and the last x blocks.
But pruned nodes are unable to validate transactions.  The network benefits more from full nodes.
A pruned node validates all transactions. All nodes (pruned, and non-pruned) will download the entire blockchain, and will keep track of the UTXO set. Pruned nodes will delete block data older than x blocks (more specifically, it will limit the total block data to x GB), while non-pruned nodes will retail all blocks. The main difference between the two types of full nodes is that one has access to all transaction data, and can serve new nodes all previous blocks, and the other cannot do either.

Quote from: PrimeNumber7
the TXID itself does not allow for nodes to validate that the transaction is valid.  I am also unaware of any way that a node would be able to update the UTXO set based on the various TXIDs of transactions included in a found block.
When a new transaction is created, it would include the details of the transactions it spends. All nodes would be able to see these details in the mempool and can validate them from there.  Once confirmed, the found block would only contain their txids, and it would be your choice whether to save or discard the details.  The only nodes who need to save transaction details are the owners.
I don't see how nodes would be able to validate if a block is valid or not under your proposal.

In order for a block to be valid, all consensus rules must be followed. I don't see how nodes would be able to validate that each transaction contains no inputs that have been previously spent, and that all inputs are valid.

Further, not all transactions that are included in blocks will be in all nodes' mempools for a variety of reasons. Some transactions have not even been broadcast publicly before a block is found. It is important to remember that each node has its own mempool, and the transactions that are stored in the mempool from node to node will vary.

The lowest fee rate you can set for your transaction is 1 sat/vbyte. That's the current minimum relay fee rate and any transaction with lower fee rate would be rejected by the nodes.
As said, in 2022 the lowest fee you can set is 1 sat/vByte.
Technically lowest fee is zero.
Practically it is 1 satoshi/vbyte so the total depends on the tx virtual size.
Most clients will only allow users to set a fee rate when crafting a transaction, however, it is possible to craft a transaction with a 'flat' fee, for example, x sats. Or in the case of what j2002ba2 found, 1 sat.

111  Economy / Service Discussion / Re: Suspected Tornado Cash (Ethereum mixer) developer arrested on: October 19, 2022, 09:55:51 PM
@PrimeNumber7. The developer of Tornado Cash is the person being held in a prison for charges the government are not quite certain what. This might end in something similar to Ross Ulbricht where it was possible that the judge, the jury and everyone working in the court knew already what type of sentence was going to be given.

In any case, have these type of sanctions gone to the extreme? Clearly yes.

It also appears that Ethereum users will need an application to know if certain coins came from Tornado Cash hehehehe.



On Wednesday, David Hoffman, a crypto evangelist and host of the popular industry podcast Bankless, filed suit against the Treasury Department over sanctions it issued earlier this year against Tornado Cash, a tool that anonymizes cryptocurrency transactions. (Coin Center, a think tank for the industry, joined him in the suit.) According to the Treasury’s Office of Foreign Assets Control, the department’s sanctioning arm, the blacklisting is a response to the Lazarus Group, the North Korean hacking army it claims has stolen and laundered some $500 million. The problem, though, is that Tornado Cash isn’t a company or a person — it’s code that lives on the ethereum blockchain, and there’s no way for anyone to control or destroy the protocol. Since Tornado Cash isn’t an entity, it can’t appeal. It’s up to people like Hoffman, who claims he may be forced to affirm every year that he’s not a criminal — not because he has used it or has some connection to North Korea, but because he once had someone send him money using Tornado Cash.

Source https://nymag.com/intelligencer/2022/10/have-u-s-crypto-sanctions-gone-too-far.html
If sanctions are being placed on an entity that does not exist, it is a statutory defect.

There are many cases in which the outcome is clear to most involved in the case because the evidence is clear. The evidence against Ulbright was strong, and there is additionally evidence that Ulbright knew what he was doing was going to result in a long prison sentence if he was caught. I think the law is less clear in the case of Tornado Cash.
112  Economy / Scam Accusations / Re: [Cryptoplay.io] CRYPTOPLAY CASINO SCAM - RIGGED FAIRNESS on: October 19, 2022, 09:50:44 PM
I personally think using the same server seed, and a nonce makes verifying bets easier for the player (which, in turn, will add trust to the casino), however changing the server seed after each bet will not invalidate the provable fairness, provided the hash of the server seed is known to the player before they make each bet.


In this particular case, assuming the screenshots are genuine, it appears there are two different server seeds for the same bet. If the casino cannot provide the actual server seed that hashes to fc86...15a to allow the player to verify the outcome of the bet, the casino is not provably fair.
What is the point of PF if the different server seed hashes are provided to the user on a particular seed? To prove the fairness and verify bets must be done through Server Seed + Client Seed + Nonce, PF casinos have to provide Hashed Server Seed of Server Seed since the user has to know the Hash of Server Seed that is used to verify bets and user has to match Hashes during the verification process. If Casino cheats with another Server Seed, the provided Hashed Server Seeds will be different, simple as that.
Code:
"Server seed hash is a warranty that can be applied to max 1 bet", "It would only work for one bet, this is why the hashed seed is a warranty only for the first bet, otherwise it proves nothing"
I am 100% sure this is not how Provably Fair works and curiously made a new seed on CryptoPlay casino to check if Hashed Server Seeds are different before/after changing seeds on the same or different nonces as Support member says it is applied to first bet?!..  The Hashed Server Seeds are the same on all nonces(1,2..100) during making bets (before) and checked the same bets after: Resetting seed for checking previous one doesn't change the Hashed Server Seed.  Support obviously lying!

In general, a server seed is going to be unique for each player, because once it is revealed to one player, any other player can potentially learn the seed, and bet accordingly.

As I mentioned previously, if the server seed is constant, and a nonce is used, it is much easier for players to verify bets, than if the server seed changes after each bet. However, changing the server seed after each bet does not remove the provable fairness. If the server seed changes, the change will need to be displayed to the player in advance.

In this case, it appears that the representative is not understanding your concern, or they are intentionally answering a question you are not asking, if your screenshots are genuine.

It would have been a 'middle ground' that would make some people think a bit more. Taking the threats / plagiarized content off the table since I have been here for 8+ years and have a good history I would have to do something EPIC to get a perma ban. And there are more then a few users like me. This way the mods have another tool in their pocket.

This is not true. In order for you to get a perma ban, a mod/admin would need to "press the ban button" on your profile. If ban appeals were eliminated, you would lose the ability to contest a ban if you were banned in error for example.
114  Other / Meta / Re: Eliminate ban appeals, but change the perma ban at the same time. on: October 18, 2022, 11:23:41 PM
We already have something as you describe. I have occasionally seen the mods allow someone to create a new account after being banned so they can continue participating in the community. It is pretty rare for the admins/mods to explicitly allow this, however, there are also many instances in which this is implicitly allowed as many who have been banned come back as new users, and most of these people do not get banned for ban evasion.

I don't think ban appeals should be eliminated. A ban appeal is an opportunity for the person banned to present evidence/an argument that the mods may not have considered when deciding to ban someone. When done publicly, it also allows the community to weigh in regarding the person's benefit (or possibly lack thereof) to the community, which should also be considered.
115  Economy / Scam Accusations / Re: [Cryptoplay.io] CRYPTOPLAY CASINO SCAM - RIGGED FAIRNESS on: October 18, 2022, 10:38:57 PM
In order for a casino to be provably fair, it needs to commit to the server seed before the bet is placed, and allow for the player to provide some additional input to be combined with the server seed (often referred to as the "client seed"). Once both the casino and player commit to their own respective seeds, some operation needs to be performed on both seeds in order to calculate the outcome of the bet.

Due to the fact that the same calculation done to both seeds would produce the same outcome if repeated, after each bet, the casino will need to change either the server seed, or add a nonce that is also part of the calculation that will change after each bet.

I personally think using the same server seed, and a nonce makes verifying bets easier for the player (which, in turn, will add trust to the casino), however changing the server seed after each bet will not invalidate the provable fairness, provided the hash of the server seed is known to the player before they make each bet.

@PrimeNumber7. However, the code for Tornado Cash is opensource which makes it no single person's property. There is also an argument that if a car was used to do a crime, can the government go after the creator of the car?
Code being open source does not mean that no one owns said code.

Many open-source projects attach one (or more) of various licenses that allow others to freely replicate and/or modify their published code freely.

Open-source or not, someone had to publish the Tornado Cash code onto the electrum blockchain so its smart contract can execute. This person would, IMO, would be the one who "owns" this particular instance of the code.

Also, was it not argued before that code is free speech? I have heard this mentioned many times in the cryptospace before. 
This is one of the claims in the lawsuit cited in the previous article you posted.

I think the free-speech claim has more merit for the developer of Tornado Cash than for its customers/users. I don't think the users of Tornado Cash are actually effectively saying anything by using its service.
117  Other / Meta / Re: About rule 32 - When will it be serious violation? on: October 16, 2022, 05:58:03 AM
So when will violations like this become so serious?
when a post got deleted, a member will receive an email and the reason why his post got deleted. if the member is human, he will obey and not do it again, if not, possible he wasn't human. So, because these rules are made for humans, there's nothing we and mod can't do.
I haven’t had any posts deleted in a long time. But unless something has changed recently, the member will only receive a generic message saying that their post was removed by a moderator. It won’t give a reason. The single generic message says that they should not make posts that break the rules, but that is really not helpful
118  Other / Meta / Re: About rule 32 - When will it be serious violation? on: October 15, 2022, 11:18:52 PM
I've been utilizing a user script by TryNinja recently. I had a half baked version that I made prior to it, but their version is fully fledged, and pretty much covers all basis'. So, I've started to log certain problem users, for further review down the line if there's other reports made against them. Again, this doesn't really eliminate the issue of multiple moderators handling the reports, but it does eliminate the second issue of forgetting.

When a moderator takes action that results in a report being marked as "good", they could also classify the rule violation as one of several of the most common reasons that real users have action taken against them (along with an other category). This would benefit the administration in two ways:
1 - it would make it much easier to determine the validity of a ban request for a particular user
2 - it might uncover communications issues that certain (groups of) people don't understand certain rules
2a - the impact of the rule violations can be more easily studied to understand the impact of said rules, which may lead to the tweaking of rules to further improve the user experience of the forum.


To answer the OP's question, the mods are not in the business of banning users. To ban a forum member means to remove them from the community, and that is not what the forum administration wants to do on a regular basis. The mods are in the business of keeping the forum a place where various topics can be easily discussed, in part by enforcing the various rules of the forum. A forum member is banned only as a last resort, and a ban is typically seen as a negative outcome. Obviously, in some cases, there are situations in which banning a forum member is necessary.
119  Economy / Service Discussion / Re: Suspected Tornado Cash (Ethereum mixer) developer arrested on: October 14, 2022, 11:23:42 PM
News update.

Coin Center has filed a lawsuit versus the OFAC or Office of Foreign Assets Control. This department is under controled by the Treasury department of America where our favorite grandma, Janet Yellen is the head of this department.

In any case, I do not really understand the 4 claims in the lawsuit but I ask the people who do. Does Coin Center have a case or will the courts keep blocking this until it reaches the supreme court? This might be something similar to Larry Flynt's landmark case about the protection of free speech.


I hope that "Coin Center" wins. I don't think there is statutory authority to have Tornado Cash on the OFAC list. The government might argue that the coin on Tornado Cash is the property of the developer, who I believe is a foreign national, and this would get around the argument that the government cannot sanction a smart contract. I don't see any other argument supporting the sanctions.

Both the sanctions and the lawsuit are making what I believe to be novel claims, especially around the statutory authority. It is difficult to predict how lower courts will rule, however, I think this is a case the Supreme Court will ultimately decide.
120  Other / Meta / Re: Why there is NO meme category in this forum? on: October 08, 2022, 07:24:19 PM
I think that posting memes much of the time will be against the rules, specifically the rule against posting no/low value posts. This is a discussion forum. As such, posts should be part of a discussion.



https://www.hrwhealthcare.com/blog/what-do-you-meme-what-the-behavioural-science-of-memes-can-teach-us-about-communication/
lol.

Maybe so, but much, if not most of the time, a meme isn’t going to contribute meaningfully to a discussion, especially when it is all that’s in a post.

I also don’t think it is realistic to have a discussion using memes. People could create memes for each post, but that would be bad for people who don’t speak English — it would be very difficult to translate the text on each picture.
