Thanks for noting. I have edited my vote.

Out of curiosity, but how does one change his name? I mean, what stops him from renaming again to Symtrick, or whatever? I had read that it costs 50 BTC to change your username (for VIP), but even that is once. Has it lowered since then, or maybe even completely free after you reach theymos?

3. It forces high fees all the time, because even if blocks will be full, then your self-transfer will always fill the remaining space, and make some fee market.
Doesn't that mean that the attacker has to frequently pay high fees to sustain this attack? Moreover, why does "wasting time on dummy transactions" centralizes the network, and why do we call it "wasted time" since they are regular transactions, just like any other honest nodes would either way verify.

1. Primarily, this attack affects mining pools and other full nodes. It is important to understand that the bigger the block with a large number of self-transfers, the more time and resources are required for other nodes to verify such a block. This gives the attacker a time advantage in the block verification process, leading to a slowdown and decreased efficiency for competing mining pools.
That is probably answering my second question. May I suppose that this particular attack influences the network by orders of magnitude more when the block size limit is dynamical?

(Also, am I talking to a chat bot?)
1123  Bitcoin / Bitcoin Discussion / Re: A good or bad way to avoid high transaction fee? on: December 23, 2023, 03:36:21 PM
Sorry if this sounds like I am late, I am just knowing that Bitcoin is available on Binance chain
"Bitcoins" in Binance chain hold the same water as "IOU bitcoins" in a bank's spreadsheet. There is peg as long as the bank doesn't go bankrupt. Which reminds me of why we have Bitcoin in the first place.

A crypto newbie that I introduced to Bitcoin came to me some hours ago saying he found a way to escape the Bitcoin high transaction fee.
Look. If he's into cryptocurrencies just to make profit using Binance, then buying and selling real bitcoin and being required to pay high fees etc., is reasonably an inferior solution comparably to just buying and selling IOUs.

Removing Wifi/Bluetooth chip or driver from smartphone usually is far harder, so your option usually is limited to always on airplane mode.
In my opinion, nobody should even get in that trouble. Smartphones are the exact opposite of an airgapped device. They are designed to connect to as many networks as possible. You'll have to remove modem, Wi-Fi chip(s), antennas, bluetooth module(s), NFC, GPS I think, and even radio chip? I lost count, maybe there are even more.

I am of the opinion that a properly airgapped old laptop is more secure than the majority of hardware wallets out there, if you know what you are doing.
Alternatively, if you don't know what you're doing, buy yourself a signing device like SeedSigner. It requires minimum technical knowledge to setup, and is completely airgapped.

Since when do you report the specific forum topic that acted as the announcement page of the product you advertised? This sounds similar to filling "cpuminer" when reporting your mining profit.

I guess it varies from countries to countries, but in my place there isn't even a tax framework where you can report bitcoin, let alone the place where you got your job, or the product you advertised and got paid in bitcoin. Please address to an expert (lawyer or accountant) if you haven't already, because it doesn't seem right to reporting everything related to your forum pseudonym.

Big respect to the family member that preferred to use the money for a contest. I didn't know we lost a forum member, may God bless his soul.



Disclaimer: I'm a terrible predictor.

In last year, we moved from $16k to $20k, which was a nice ride; people forgot about FTX and moved on. In January 2022, we fell from $47k to $43k, and then we plummeted. Things were bearish for a whole year at least. In the last few months we have experienced very good levels, from $20k to $40k. I personally don't mind if it drops by a 10%, so I'll just say that with fingers crossed.

$38,700

I have following RPC code. It runs on local fully synced bitcoin core node.
You'll have to be a little more explanatory. Where is this code from? Is it yours? What's the library you're using? Judging by the fact that it's C#, may I suppose it's NBitcoin?

For example for address 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa it returns 22.73242908 BTC, instead of correct 72.74245948 BTC.
That particular address is the exception to the rule, because it was rewarded with the 50 non-spendable bitcoins of the genesis block. The correct amount of spendable coins is 22.73242908.

Judging by the code, it gets the total balance by summing the UTXOs. Since the block reward of genesis isn't UTXO, it doesn't count it.
1129  Other / Meta / Re: To login I had to go thru over 50 captcha is this normal? on: December 22, 2023, 08:19:36 PM
it's not normal... AFAIK, it's not even about your IP and stuff... It could possibly be a glitch for everytime it tries to display the images on the captcha.. it happened to be and I know how fraustrating it can be.
It's mostly the restrictions which come with Tor browser such as fingerprinting protection, no permanent cookies, and the shared IP addresses of the exit nodes.

I hope you get over your challenges...it ain't over yet.
I'm standing strong. Thanks for the interest.  Smiley

When using Tails, there are a lot of stuff that can go wrong, and your machine might stop booting into it. That's regardless of the quality of the USB stick, it is simply common in Tails. So, never store anything important in the persistent storage, or back it up. Be sure that you'll have re-burn the image multiple times in the stick.
1130  Bitcoin / Project Development / Re: Are dices for generating seed words fair? on: December 22, 2023, 04:22:22 PM
Do you like the ideia of adding a coin flip when i am at 10 numbers in order to get the number 11  or this is bad for entropy?
I like the idea of using von Neumann's method and not some sketchy method you just invented. Use what is tested and reviewed.
1131  Bitcoin / Project Development / Re: Are dices for generating seed words fair? on: December 22, 2023, 03:40:58 PM
how do you convert the 1 to 6 in a dice to 0 and 1 to get a seed word?
There are lots of ways. One simple way is to hash the dice result record, e.g. sha256("262351..."); this one might decrease the entropy by a little (here's why). Another simple way is to count bits according to this array:
Code:
1: 00
2: 01
3: 10
4: 11
5: 0
6: 1

That's faster than counting {1, 2, 3} as 0 and {4, 5, 6} as 1, because it adds 1.66 bits on every dice roll, on average.
1132  Bitcoin / Project Development / Re: Are dices for generating seed words fair? on: December 22, 2023, 03:03:17 PM
So this is always a 50% 50% making that dice like a coinflip. Am i thinking right?
Well.. no. That's the case only if the dice is completely unbiased (which is never the case). If, say, {1, 2, 3} have 20% each, then {4, 5, 6} have 13.3% each. This will produce the same result as a coin that is 60% heads and 40% tails.

It doesn't make sense to roll a dice as if you're tossing a coin; toss the coin in the first place using von Neumann's method. It will eliminate any bias and produce theoretically complete randomness.
1133  Bitcoin / Project Development / Re: Are dices for generating seed words fair? on: December 22, 2023, 02:41:17 PM
does anybody really trust casino dices?
It is said that casino dice is the most fair piece of dice.

is the entropy for a die really over 1 bit? if the seed its all zeros and one even if the die has 6 faces its always 50% 50% because we will have to do something like from 1 to 3 choose ZERO from 4 to 6 choose ONE.
As I have showed in here, a dice that produces near 1 bit of entropy is understandably insecure from the human eye. You can check out how frequent '1's I have got with 75% frequency, it makes a splash. And that's 1.29, with 1 bit it's even more clear that you shouldn't use that dice.
1134  Bitcoin / Wallet software / Re: Mempool fees and Solutions on: December 22, 2023, 12:47:40 PM
This means despite they not breaking the consensus rules, preventing these transactions is fixing that exploit and it is not censorship.
It is not censorship to fix an exploit in the protocol, but the way I view this is, you hate being forced to pay high fees and Ordinals is the main cause of this rise in fees.

I'm in favor of fixing this on a standardness level, but please don't hope that this will disappear. There are millions of dollars paid in fees alone, in the last few days. Making them non-standard is not going to censor them. There's already enough demand to bypass this on a standardness level.

The only way to stop it is with a softfork.
1135  Bitcoin / Project Development / Re: Are dices for generating seed words fair? on: December 22, 2023, 11:21:39 AM
after reading more about the subject i come to the conclusion that dice rolling is better even if i dont use fair dice.
It is faster, and most likely sufficient if rolled enough.

Am i thinking correct?
Yes, if you roll it 100 times, then even if it seems completely biased towards 1, it will generate enough entropy. That's the Shannon equation for measuring uncertainty.

I have demonstrated it in here. The probability of a number being 50%, and the rest 5 being 10% each, still gives 2.16 bits of entropy on each roll, which is 0.42 less than in a completely unbiased dice, but enough nevertheless if you simply roll it a few times more.

It simply takes time to verify that the dice won't fare worse than that. In contrast, coin flipping using von Neumann's method necessitates no precautionary measures.

Even more of them if full nodes start rejecting the Ordinals Attack and the scammers are forced to use third party software to circumvent a lot of stuff...
I don't believe you can stop this without messing with consensus rules. Standardness isn't going to help. Binance essentially funds this, and Binance is literally mining. Newbies can buy and sell this nonsense using third parties, and maybe at this time it'll be worse, because we will have an inaccurate mempool.

At the same time, 546 sats is the minimum UTXO size allowed in Bitcoin, so it looks like people fill blocks with dust outputs.
It is the minimum standard UTXO size allowed in P2PKH outputs. But, this one is P2TR, where the dust threshold is 330.

Question for everyone more technically savvy than me: Could those be direct payments to the miners for some reason? Because if you think about it, you will see that these transactions pay for example 50,000 sats on fees (to the miners) and 546 sats to an address.
It could be a miner payment, which saves space for another output. But, to me it seems more like someone testing taproot.
1137  Bitcoin / Bitcoin Technical Support / Re: This is beyond craziness on: December 21, 2023, 09:47:53 PM
The only thing we know for sure is that someone attacks Bitcoin with transactions like this: https://mempool.space/tx/51818e244c6dd93ece167ab78fe934068e229cdccd54d294e88226d2bb9f800d
To me, it rather seems like someone's attacking their own pocket.

There is a huge amount of dust transactions. So, this is strong evidence that some people spam the network and one of the possibilities is that they use money earned from selling ordinals.
Why is this particular transaction considered spam? I see a multi-sig paying another multi-sig and a miner. Sure, the dust output is weird, but how's that harmful?

Based on your logic, we should do nothing to aware people of phishing and scams as "if that's what they want to do and it's in their budget, then we should let them".
No. Based on their logic, we should absolutely warn them about scams, but if they nonetheless want to visit the phishing site, we shouldn't deprive their right.

You can logically deduce what is happening...
All I can see is people playing around with another greater fool theory financial instrument. The fact that miners get paid along the way doesn't mean they invented it in secret.

Most of us are long past using "conspiracy" to discredit logical opinions rather than providing valid reasoning to rationalize the opposing opinion.
All I'm saying is that extraordinary claims require extraordinary evidence. I didn't claim that miners did this in secret, you did. So, it is you who needs to back this up.
1138  Bitcoin / Hardware wallets / Re: Fuck you ledger on: December 21, 2023, 08:20:59 PM
The crazy thing is that I know both of you have extensive knowledge of hardware wallets, and if you're both arguing about something so fundamental, can you imagine how confused people like me--who don't have the technical knowledge to evaluate these claim on their own--are, and how jaded some of us are now that it seems like most if not all HW wallets can theoretically extract a user's private keys?
I get your concern, let me break the situation down for you.

Humans make mistakes, like really often. It applies everywhere, including software engineering and designing. If a software is exploited in an Internet connected device, the attacker can steal your keys. Being airgapped grants you this invaluable property that even if things get really fucked up, it is physically incapable of sending anything anywhere.

Trezor is not airgapped. Even if we assume they are coding with the best intentions, there's this chance of an attacker exploiting their software and taking advantage of the fact that the device can communicate with the Internet. And we know they don't have the best intentions when it comes to privacy as they're cooperating with Wasabi (references on why that's a red flag can be found on dozens of topics in this board) and had enforced a dystopian Address Ownership Proof Protocol in the past.

Nobody claimed Trezor is insecure. What is being said is that Trezor has the ability to surveil you, and is definitely less trustworthy than an airgapped device.
1139  Other / Meta / Re: To login I had to go thru over 50 captcha is this normal? on: December 21, 2023, 07:47:20 PM
I like the phrase privacy comes with a cost . It is that price that I am not willing to pay, but anyone who is overly private will pay the price. With the stress one goes in real life and other challenges of life, I do not think that I have the patience to try pass captcha more than 5 times
It depends on which sites you visit. Is it just bitcointalk? You don't need to submit a captcha more than once. Is it a couple of news sites? Maybe you encounter one or two everyday. Is it social media? Probably tons, if it even allows you to pass with Tor.

I don't know how much of it's reliable or efficient.
Tails runs on memory. You can save a few files on your persistent storage, but everything else will be wiped up every time your machine shuts down. If disk usage is an important part of your job, then use another OS. But, generally, it is very convenient and portable.
1140  Bitcoin / Bitcoin Technical Support / Re: This is beyond craziness on: December 21, 2023, 07:39:28 PM
I can assure you, these idiots are not the ones who are inflating the chain. It is intentional work.
To me it seems like a coincidence. The theory that Ordinals were invented to fill the miners' pockets is nothing more than conspiracy, unless you have tangible evidence.



Do we have any statistics about Ordinal profitability? I mean, the medium priority fee right now is 154 sat/vb, and an Ordinal transaction is way above the median size. If it takes 10 bucks to have a median sized transaction confirmed, then how much does one pay to create an Ordinal? A thousand? And another thousand to sell it? How's this profitable?
