My transaction is Stucked since 7 weeks 😢 and I didn't come forwards.

First of all, how do you know the transaction stuck? Did someone say that the transaction stuck? Did you check the transaction status on your wallet or blockexplorer?

transactions sre getting confirmed with 1 sat/byte. you might be having a problem with transaction broadcast (or some other problem with the transaction).
This is the reason why I am surprised the OP transaction is stuck for 7weeks when tx with 1 sat/byte will confirm within 1008 blocks ( ~10080 min) which I believe is 7days.

I think you haven't send Bitcoin transaction in long time. In last few months, 1 sat/byte usually could be confirmed within next 1-4 blocks. You might want to check block explorer such as https://mempool.space/ to know current situation.

Bitcoin decentralization would receive a great blow if somehow Satoshi come back from nowhere.  He would become something like Bitcoin CEO or ambassor, and decisions would somehow become centralized on him.

That's assuming Satoshi is still alive and participate on Bitcoin development/adoption. I fear more Satoshi's background/identity could be used to attack Bitcoin reputation.
1863  Bitcoin / Development & Technical Discussion / Re: Intentionally make a transaction slower on: March 21, 2022, 12:25:22 PM
Your question doesn't make any sense,if you want your transaction to arrive at X date just send it at that X date why you're going through all this hassle just to make it slower.

While OP never state his intention, i can see why he ask such question. Some bank have feature "Scheduled Money Transfer" where customer just need to configure the schedule few times. It's more convenient than sending the money at specific time.

To subsidize such transactions, the miner would need to modify the transaction and add more inputs, because block checks should (correct me if I'm wrong) check all transactions on validity one-by-one.

Is it even possible to modify signed transaction?
1864  Economy / Service Discussion / Re: List of VPN Service Providers - 2021 on: March 21, 2022, 11:50:08 AM
Since one of the things I use VPN for are streaming services (Netflix and Amazon mainly), are there any VPNs on the market (other than ExpressVPN which I know works very good for this) that can handle 4k streaming without issues, with high amount of available servers that consistently work for streaming sites?

There aren't many VPN which simultaneously offer decent privacy and high speed for streaming. AFAIK only ProtonVPN offer both. I only used free version though with slow home internet connection, so i don't know if it can handle 4K streaming.
1865  Bitcoin / Wallet software / Re: The default Wasabi Wallet coordinator will start censoring "illegal" UTXOs on: March 20, 2022, 12:19:40 PM
This is only a small mitigation in my opinion because we will face the same conundrum as we face in something like Electrum (although Electrum isn't privacy oriented).
So what's the solution here? Every user running their own coordinator, all of which communicate with everyone else's coordinator in a decentralized manner, much like the bitcoin network itself?

Alternatively, use protocol where interaction between user isn't needed. If you're looking for example, check SNICKER[1-2] or Mimblewimble protocol.

Samourai Wallet is already unrivaled in transaction privacy, but the default configuration is still subject to network level privacy loss. Hosting your own Dojo allows you to simply bypass our default servers and circumvent these concerns.

So yeah, perhaps this information should be more visible, but they are not actively hiding it.
Honestly, it shouldn't even be an option not to run your own node if this software is supposed to be privacy-first. Their 'default nodes' shouldn't even exist, they should all be taken offline if they're serious about privacy. I have a gut feeling we'll end up with a 'Wasabi situation' sooner or later.

Alternatively, they should implement BIP 157/158 if they wish to support user with very limited resource (mainly internet bandwidth). But currently they don't support it[3].

1866  Bitcoin / Development & Technical Discussion / Re: [Megathread] The long-known PoW vs. PoS debate on: March 20, 2022, 09:52:09 AM
The article mentioned it's possible since the smart meters have access to your network and analyze unencrypted data. Encryption could solve this privacy concern.
its not so much about access to network to analyse data(computer bytes of your PC). it about knowing power consumption patterns EG knowing the average power of a TV and a coffee maker/microwave. and they can compare any variable of power consumption to when TV shows go to commercial break and people have a coffee or warm up a snack to know which program they are watching due to the timing

I know you mentioned more common method, but that research specifically utilize network access to perform MITM.

heck they use to allow police to be informed when people were using high energy 24/7 as it was believed that those houses were being used as weed growfarms
even a few years ago a few people got swatted by cops due to high 24/7 consumption thought of as being weed growing, but ended up being found to being an asic farm
https://www.theverge.com/2021/5/28/22458632/bitcoin-mine-mistaken-cannabis-growing-operation-police

And it's proof such method isn't reliable to determine how people use electricity.
1867  Bitcoin / Development & Technical Discussion / Re: Intentionally make a transaction slower on: March 17, 2022, 12:20:43 PM
Can we think of any other ways?

Setup script to broadcast your transaction on specific time/date.

Also, it used to be possible to make zero-fee transactions. Is this still possible in 2022?
You can manually construct a transaction even with negative fees. The question is will nodes or miners accept such a transaction?

Almost all nodes won't accept 0-fee transaction since it's default Bitcoin Core behavior. Miner might include it, but you need to find out how to make your transaction enter miner mempool.

Lain halnya kalau misalkan download/menggunakan sources dari Electrumnya langsung, minimum versi Python setidaknya harus dipenuhi, mengenai dependencies-nya sudah langsung terdapat dalam source code.

Menurut website electrum, dependency harus diinstall secara manual/terpisah jika melakukan installasi dari source code.

1. Jadi ada yang urgent juga yaitu Minimun phyton 3.8. Laptop saya masih di bawah itu jadi mesti update ke versi baru dulu untuk lanjut ke versi 4.2.

Saya sudah update AppImage di Linux, ini tampilan aupdate GUI

Jika menggunakan AppImage di Linux, tidak perlu memperhatikan versi Python dan library yang digunakan. AppImage yang dibuat secara benar menyertakan semua program dan library yang diperlukan.
1870  Bitcoin / Wallet software / Re: The default Wasabi Wallet coordinator will start censoring "illegal" UTXOs on: March 17, 2022, 09:45:26 AM
In any case I believe both Wasabi and Samourai wallets are unpopular and unreveiwed softwares (despite what it may look like from their community). They both have some degree of shadiness which is not something you want in a privacy oriented software!

There aren't many alternatives though. Besides those two, i only could think JoinMarket.

I'm not familiar with Wasabi (though I've heard the name before) or coinjoin.  Is Wasabi a centralized wallet, like a web wallet?

Wasabi is non-custodial wallet. You also have option to connect Wasabi to your own full node.
1871  Bitcoin / Wallet software / Re: The default Wasabi Wallet coordinator will start censoring "illegal" UTXOs on: March 16, 2022, 12:05:31 PM
I was going to complaint that Samourai Wallet only available for Android, then i found out Whirlpool is separate software and available on Desktop.
I always had the same issue with it (I prefer desktop software), but Whirlpool for the desktop requires you to install Java, which I'm not particularly fond of. They should maybe package it with the binary or something like that; for now I'll give it a pass.

They have AppImage which should bundle all dependency (including Java). But what's your problem with Java? If you don't want install closed source software, you could install OpenJDK.
1872  Other / Beginners & Help / Re: passphrase instead of password on: March 16, 2022, 11:39:03 AM
But there's a problem too: if one knows you use only words from a certain language, your passphrase can be brute forced with dictionary attack.

Knowing the language alone usually isn't enough to brute force within reasonable time/resource, unless you only use very few words, the attacker have unlimited try or/and protected by weak hash algorithm. For example, average adult English speaker have a vocabulary of 20K-35K words[1]. Assuming they use 4 as their passphrase, you'll need to make 20000^4 (1.6x10^17) attempt.

1873  Bitcoin / Development & Technical Discussion / Re: Can Quantum Computer's destroy Blockchain and Bitcoins[SHA-256 specifically] on: March 15, 2022, 11:47:39 AM
BTW, that's just for one type of addresses. If you wanted both Legacy (1) and SegWit (3, bc1) you'd have to triple the effort.

With recent Taproot update, actually it's 4x effort. Native SegWit have prefix bc1q while Taproot have prefix bc1p.

You could find ways to compress all this, though. For instance, private key 1 doesn't need to take 32 bytes.

Alternatively don't store private key without coin.

In other words if Wasabi team were so worried about providing users with a privacy enhancing method, instead of "bending the knee" they should have eliminated the need for a centralized server.

It would be great if it's possible. But i doubt it's easy task, especially with large participant.

If they really hate it, at least they should give user option to use different coordinator. I expect someone will try to run their own coordinator.
Actually, there has always been an option in Wasabi Wallet to connect to your own or any other existing coordinator to be less reliant on the Wasabi team that runs the biggest coordinator. Yeah, the reason most people have been using zkSNACKs coordinator is that it is the most popular one. The more popular the coordinator is, the bigger crowd it attracts. The bigger the crowd is, the easier it is to obfuscate your transactions and harder to attack the wallet with Sybil attacks.

I know such option exist, but last time i checked,
1. You need to use terminal to change the coordinator. It's not user friendly and most users don't know such feature exist.
2. The documentation never state you can use different coordinator.

I feel it's meant for debugging/advance user rather than additional feature for all users due to reason i mentioned above.

Here is a fork of Wasabi Wallet called https://chaincase.app/, which is available on iOS and which is running its own coordinator. You can connect your Wasabi Wallet to this coordinator using the following method: https://github.com/chaincase-app/chaincase/discussions/119

I've heard that wallet before, but does anyone know how often CoinJoin process happen? Waiting few days for single CoinJoin isn't practical.
1875  Bitcoin / Development & Technical Discussion / Re: Bitcoin and smart contracts (RGB Protocol) on: March 14, 2022, 11:56:40 AM
What happened to this project? I just opened the URL from my bookmarks and it shows a 404.
-snip-

RGBFaq is also not accessible apparently.

I can access RGBFaq normally, it's possible the website was down.

I'm not sure what happened exactly but you can still access the content of the page from Github: https://github.com/RGB-WG/rgb-org.github.io/blob/master/index.md

Since there's no discussion on that repository (unless the developer/contributor use different place), it's unintentional and likely no one about this problem.
1876  Bitcoin / Bitcoin Technical Support / Re: NEED HELP WITH 2010 WALLET.DAT FILE on: March 14, 2022, 11:24:55 AM
Have you created raw copy of your harddrive? It's safer to make raw copy and perform deep search from the copy.

I would recommend to use one of existing tools, like https://github.com/pierce403/keyhunter

PyWallet also have option to scan drive[1], https://github.com/jackjack-jj/pywallet.

And the most likely you will not be able to extract your private key if wallet was encrypted with password.

If OP remember/identify date of wallet last access correctly, it shouldn't be encrypted. Encryption only available since Bitcoin Qt 0.4.0 which released on late 2011[2].

1877  Bitcoin / Wallet software / Re: Securing Your Seed Phrase with Washers on: March 14, 2022, 09:44:46 AM
Also I know words are uniquely identified by the first 4 words, but I think the time save is not comparable to the increased risk in case of data loss: what if I print only 4 words, and a strange accident damages 2 letters of every washer?so I deliberately decided to print all letters.

Actually it's good point. Reducing chance of data loss is more important than saving time during setup.

FYI, you could save some time if you only write first 4 character of each word. Although i'm not sure it's applicable for seed/mnemonic on different language which have different specification.
I'm pretty sure that it's a requirement for any language's 'seed alphabet' that the words need to be uniquely identifiable by the first 4 letters.

I checked the specification[1] and looks like it's true for any language which use alphabet similar with English alphabet. But it's not applicable to CJK characters[2-4] which might use less than 4 character.

That's probably due to UK court order.

Not probably, but definitely. Here's relevant discussion https://github.com/bitcoin-dot-org/Bitcoin.org/issues/3698.

You can just download it from the official website anyway: https://bitcoincore.org/en/download/ (it's displayed at the top of forum pages)

And if you use linux, there are alternative to download Bitcoin Core from Snap, Flatpak (it's unofficial, so DYOR) or your linux distro repository.
1879  Bitcoin / Development & Technical Discussion / Re: Charging rent on the bitcoin network, is that a bad idea? on: March 12, 2022, 11:22:11 AM
why are people trying to make it sound like the bitcoin network is soo expensive when no one ever complains about youtube or netflix (1gb SD, 3gb HD, 7GB 4k.. for just 2 hours)

While i agree with block size increase, your comparison isn't fair. Simply using few hundred GB/month is easier than verify and store it on your device.

Quote
Yeah I guess more security but in reality, you can sign an offline transaction and broadcast it without needing to be a full node. Isn't that just as secure?
And you sign that transaction based on... block explorers? Some data from SPV nodes? You fill your transaction inputs based on trust that those previous transaction outputs really exist. But in case of some attacks you could be convinced to sign coins that never existed at all.

Or attack which give you wrong balance of input which could lead to overpay TX fee.

Now about your statement that bitcoin is "the only decentralized currency in existence" that's a pretty big statement. I would be willing to grant that bitcoin is the biggest decentralized currency in existence but I'm not sure how one comes to the conclusion that it's the only one.
I'd love it if you could show me another one!
The others are either centralized or semi centralized or simply they are not currencies.

How about Monero?

That's a terrible idea: anyone can vote on a poll, which makes (alt) abuse very easy.
In some others forums that I am active on and that are much older than bitcointalk they have the option to make poll voting public, so everyone can see who voted for who. Would something like that be possible to implement here as well, forum software wise?

It's technically possible to implement such thing. But the real question is whether theymos will implement such thing, especially when new forum software is in development (although no one knows when will it be ready)?
