1901  Bitcoin / Bitcoin Discussion / Re: To what extent are Russians capable of storing their riches in Bitcoin? on: March 01, 2022, 09:42:04 AM
Let me ask all of you the same question, how is this possible???

Because if poeple would sell their rubles for Bitcoin as the ruble becomes worthless, it means somebody is selling those bitcoins for rubles, right?
I don't see a Frenchman opening a bank account and having rubles sent to him in exchange for his BTC, can you picture that?

it is kinda dicey. With the free fall of the Russian Ruble, who will really want to sell their Bitcoin for RUB when others are trying to sell out of the RUB Huh because that is the currency they are holding to trade with. I think if this has not been done already, regardless of the options they have via these DEXs it will be deficult.

While i agree with your logic, i managed to find some BTC seller who accept RUB at HoldHodl[1]. But obviously the rate isn't fair. At time of writing the post, those seller charge 4-30% higher.

While they can't use most centralized exchange, their option isn't that limited. They still can rely on decentralized website and P2P/OTC medium such as Bisq and HodlHodl to find Bitcoin seller though.

From what I've understood from here (Romanian, here's a Google translation), if it's out of SWIFT, the customers of the bank can only withdraw money, nothing else. So I expect that - in a way or another - only face to face trades could take place there.

I get your point and it's valid point when a Russian trading with foreigner. But i meant Russian trying to find Russian BTC seller where both of them use Russia bank (local bank transfer).

It's been long time since i saw PoS discussion on this "Development & Technical Discussion". I hope there won't be any chaos.

P.S. Here is a realistic risk of PoS: a lot of people have proven to see cryptocurrency as a trading tool and they will deposit their coins on a centralized exchange. All of a sudden we have one entity with a huge amount of coins aka stake that can control the PoS too.

And it already happened several times. For example, Binance, Houbi and Poliniex helped Tron foundation to perform hostile takeover on Steem network[1]. Binance only apologize[2] while Houbi make an excuse[3] without any real action.

Benchmark by CASA[1] shows some hardware wallet took long time to sign multi-sig address or failed due to PBST size.
Seems like the only work around to this then is to take the seed phrase for the Ledger hardware wallet and import it in to a standard Electrum wallet and then sign the transaction from there.

Looking at this benchmark result, i would suggest different work around which is using fewer input. But it means you'll need to make multiple transaction and pay more fees.

1905  Other / Meta / Re: Does the forum not like us using TOR or privacy applications? on: February 27, 2022, 11:50:33 AM
For starter, I get asked a captcha when using the private window with TOR. I never have to do that with the regular window. This captcha also seem to purposely make me repeat it over and over again, even failing me when I answered correctly. Needless to say, it takes quite a while just to login to the forum. I've had sites that require image captchas that I've opened in the regular window and those captchas work normally and I've NEVER had to repeat any.

If you're referring to reCAPTCHA, it's known hostile against Tor user. All you could do is following @PX-Z to avoid reCAPTCHA.



I've only experienced TOR through Brave and haven't used it in other ways and the only thing I knew about it is it's all about privacy but why do I have the feeling that this forum does not like it?

Read this warning.

Can I use Tor with a browser besides Tor Browser?

We strongly recommend against using Tor in any browser other than Tor Browser. Using Tor in another browser can leave you vulnerable without the privacy protections of Tor Browser.
1906  Bitcoin / Electrum / Re: electrum - multisig 8 of 8 on: February 27, 2022, 11:42:11 AM
I'm thinking that it may be more of a hardware wallet issue than Electrum's since it's the Ledger that can't sign.

I also think it's problem with Ledger. Benchmark by CASA[1] shows some hardware wallet took long time to sign multi-sig address or failed due to PBST size.

Since we're talking about LN (which usually used for micro-transaction),
1. Do you have minimum/maximum amount of satoshi to be held by escrow?
2. How do you handle LN channel duration when delivering physical goods could take long time (up to 1 month)?

A clean install of Debian, preferably the fully free one, with only free software like Bitcoin Core is much more secure than a clean install of Windows, even debloated.

Using exclusively free and open source software is nearly impossible, especially when we're talking about hardware driver (such as GPU and network card).

You can use Windows Tails OS How to Install Tails OS on USB flash drive for Wallet Purpose or Linux or Ubuntu

Lubuntu is more lightweight than Ubuntu. Linux is first priority, next Ubuntu if you don't want to use Windows

It is noticeable that you are also far from Linux systems.

See how popular Linux systems are today.
https://distrowatch.com/dwres.php?resource=popularity

Distrowatch "popularity" is based on page view of each distro page. It bad representation of linux distro popularity. For example, it's more likely you'll find Ubuntu user (6th position) rather than MX Linux/Endeavour OS (1st and 2nd position).
1910  Bitcoin / Wallet software / Re: Can wallet providers see what's in my non custodial wallet? on: February 25, 2022, 11:35:27 AM
While using Electrum with Tor improve your privacy, the server could know that set of your Bitcoin addresses belong to same person.
Ok, so this is a bit of a eye opener for me.. because I thought that ToR + Electrum was a safe method to protect your pseudo anonymity. So if one of the addresses you used are linked to any service you used that had KYC ...you are basically dox'ed.  Roll Eyes

Only if the server is run by government agency or blockchain analysis service. But i would treat all address as exposed.

So the central point of failure are the "servers" that you connect to .... and not the client you use.  Roll Eyes  Interesting. Can you run your own Electrum server and only connect to that, when you do transactions... or is that basically just the same as running your own full node? (Do they validate Servers for public domain use?)

Yes, you can run your own Electrum server (ElectrumX is the most popular implementation) and configure Electrum only connect to your server. From privacy side, there should be little difference (such as Electrum check latest Bitcoin price if you enable that feature).
1911  Bitcoin / Wallet software / Re: Can wallet providers see what's in my non custodial wallet? on: February 24, 2022, 12:27:42 PM
I agree with the above posts having a full node will help you protect your privacy but you can also use Electrum and setup it up through TOR which also protects your privacy.

While using Electrum with Tor improve your privacy, the server could know that set of your Bitcoin addresses belong to same person.

3. Connecting to regular nodes using bloom filters, etc. to try and sync. This can provide better privacy but also has some flaws.

As reminder, bloom filter (BIP 37) is broken and IIRC most full node doesn't enable bloom filter service. Consider wallet (such as Wasabi Wallet) which use BIP 157/158 instead.
1912  Other / Off-topic / Re: Trying to secure my PC on: February 24, 2022, 11:55:33 AM
Assuming you're using Windows and you really need antivirus, just use built in Windows Defender. While it doesn't offer best security, it's not too annoying (less false positive or annoying pop-up) and use less resource than other antivirus.

Is there any strong antivirus I can use to safeguard my PC from malware? I have few coins that runs wallet only on PC but it's very easy for PC to get compromised that's why I'm looking for a safer tool that can fight Trojans and malwares.
Under Windows, my experience tells that the stronger the security/antivirus system on your PC is, the more difficult it can be to work on that PC. It may block access to legit files or even installers (false positives or unrecognized binaries), it may remove legit program on sight (false positives), it will slow down the system (opening/reading/parsing each and every file you copy, your system uses, or just present in a folder you're opening).

Additionally, some antivirus these days acts like virus (especially the free one). They would steal and sell your data[1] or even perform cryptocurrency mining (which use lots of your PC resource and affect your electricity bill) without explicit consent[2][3].

1913  Bitcoin / Development & Technical Discussion / Re: How to deal with kernel updates on: February 23, 2022, 11:29:11 AM
Just reboot it, but make sure Bitcoin Core exit cleanly. Init system such as systemd kill any process if it took longer than 90 second.

Red Hat distros have a particular Live Patch program that installs the kernel updates on the running kernel so that a reboot is not required.

IIRC it meant to fix critical CVE without rebooting and Red Hat recommend you to make a reboot during planned downtime.

I do not believe it's available for other distros though, since Red Hat builds their own kernels.

Code:
yum install kpatch
yum kpatch auto

Any distro based on Red Hat should have such feature. If you're Arch user, you could install and configure kpatch manually.
1914  Economy / Speculation / Re: How to build a forecasting model using LTSM on: February 22, 2022, 12:29:56 PM
But, it can also be used to forecast bitcoin prices with the help of RNN (Recurrent Neural Network) if you follow the steps in this post you will gain the source code for predicting bitcoin Price which can then be implemented on the forecasting model.

No matter what model/algorithm you use, it's not reliable enough if all data you have is only past Bitcoin price. Without external data (such as sentiment about Bitcoin on twitter or latest news about Bitcoin), i expect people who use that model/algorithm could go bankrupt when something big happen (such as an exchange hacked and most funds stolen).

The only good news i have is that i know the first 6 words.

I didn't do the math, but IIRC it's computationally impossible if you don't know the order 12 words or more.

So is there a tool which can crack the seed, when i give it all my words? Would be nice if i can also say that the first 6 words are this, this and this. So it needs less time to crack it.
The tool should be free and open source/

1916  Bitcoin / Bitcoin Technical Support / Re: Full Node: (1) Ramifications of 0 in, (2) ISP Bypass for Port Forwarding on: February 21, 2022, 11:45:38 AM
Question 1: Exactly what does zero in mean? What data is missing? (In the Peers tab I see 10 User Agents and I can watch data received in real time, so data is coming in. Data  in but zero connections sounds contradictory.

"In:0" refer to 0 incoming connection. It means there aren't any node which connect to your node. You should check "Network" tab to see total data you sent/receive.

Now the linked problem. I’m showing In = 0 is because Port triggering (forwarding) settings in my router/modem via Port 8333 or a range between 1024 and 65535 do not exist, so I cannot make the changes I need.  (I have enabled Port 8333 in the LAN Wi-Fi of Windows 11 and the Firewall as well, so Windows is ready to receive via 8333.)  The port I need is closed at a higher ISP level. If this is true, and I should confirm it, a router with the settings I need will not work.

Most router/modem usually have port forwarding feature. It's possible you couldn't find it since you don't use admin account. If you're willing to share type of your router/modem, some member might able to help.

Question 2: Any work-around to bypass my ISP's restriction?

Usually it comes down to 3 option,
1. Use non default port.
2. Use VPN which allow port forwarding.
3. Configure Bitcoin Core to use Tor connection and setup hidden service.

True, but you don't need to prepare a server with 400GB+ storage to store the blockchain. Another service such as Bitcoin Explorer (which i mentioned above) also heavily utilize Bitcoin Core RPC.
1919  Other / Beginners & Help / Re: Normies want to become techy person about Technical Bitcoin on: February 20, 2022, 09:54:29 AM
Does we need to practice and learn anything about Bitcoin to understand it all?

You only need to learn the basic (which you already do) to be able to use Bitcoin.

e.g. setting up Bitcoin core, try to open new channel, try to mining yourself etc. I think that's costly enough, Bitcoin core need insane memory and to mine Bitcoin I need to buy mining rigs and many more... that's why I'm looking for the alternative (using electrum and not mine Bitcoin, but buy to hold). It's possible if I can understand those thing without practice and only read from other people experiences?

If you want to try using Bitcoin Core at lower cost, consider using Bitcoin Testnet instead which have lower blocksize.

But if you want to learn more, don't overwhelm yourself. Start slowly and from the basics. For example you can start by reading Mastering Bitcoin book by Andreas Antonopoulos then move on to more advanced understanding of the technology.

Jameson Lopp also have nice list of technical resource at https://www.lopp.net/bitcoin-information/technical-resources.html if you don't know where to continue after reading Andreas book.

Sebagai catatan, fitur yang digunakan OP hanya tersedia untuk Android versi 9 atau lebih baru.

Android 9 Pie introduced a system-wide DNS setting, so instead of changing the DNS for each individual network, you can do it in one place. However, Android requires that the DNS service supports DNS-over-TLS, so not every server will work.



Gua sdh prmh coba bagaimana lelet jaringan kalao pakai tor belum lagi captcanya karena relaynya sampai 3x alias 3 x lipat kalau pakai VPN, mending ubah DNS itu sama seperti mengakses tanpa vpn.
Tentang bitforex, ini gua akses tanpa VPN

Lancarrr bengettt

Saya tidak pernah merasakan lelet saat menggunakan TOR Browser dengan perangkat Laptop saya dimana speknya adalah Intel Core i7 Gen 10th Ram 16GB + SSD 512GB, begitu juga dengan smartphone samsung saya Galaxy A21s Ram 6GB tidak pernah lelet sama sekali. Jadi kalau mas masih pakai perangkat akses yang masih sangat rendah, mending upgrade dulu deh biar Lancarrr bengettt seperti yang mas katakan itu, karena sekarang apapun bisa diakses tanpa harus mengandalkan VPN serta tanpa harus merubah DNS yang begitu banyak Cheesy

Apa hubungan nya antara komputer/smartphone high end dengan kecepatan browsing menggunakan Tor Browser?
