61  Bitcoin / Bitcoin Technical Support / Re: Cheap & silent mini PC for Bitcoin node & blockchain explorer? on: September 09, 2024, 08:52:59 AM
You can wipe / replace the drive / whatever. If Computrace (and similar) are active in the BIOS is will follow to the new OS if the OS recognizes the fact that it's on and active in the BIOS it will use it.

The worst part are re-flashing the BIOS doesn't always guarantee Computrace (or similar stuff) removed permanently.

Back on topic ...

I just bought a GMKtec NucBox G5, with N97 CPU, 12 GB RAM, 256 GB M.2 SATA SSD, and Win 11 Pro for $160. I plan to replace the SSD with 2TB and install Linux. It is very small -- about 7.25 cm x 7.25 cm x 4.5 cm.

Previously, I had a RPi 4 node set up using the Raspibolt guide. It was slow and a little unreliable because the RPi 4 is not a very powerful processor. Problems with availability of the RPi 5 led me to buy the GMKtec setup that I mentioned above. As stability is a priority, I went with Debian Linux.

--snip--

Just wondering, how easy or difficult to open and place the additional SSD on your mini PC?

Data cost, I mean internet cost which is different from one place to another and in some countries even you have to pay a lot just for 1 or 2GB data but since you mentioned you are already up then I assume the data cost is not the problem and hardware cost isn't there any if you have already a machine with decent specs but even if you have unlimited data you still have to worry about outbound there was recently someone complaining he is consuming terabytes just for a week or less than that in that case you need to restrict the peers.

Ah, very well. Yeah I've already got the system to run it on, with no data caps up or down, so no issues there! Cheers and thanks for the clarification. Although now that you say that, I wonder if my ISP would go nuts when all of a sudden I have TB's of data going out, hah. Guess we'll find out, but "No Data Caps" is "No Data Caps" so we'll see if they stand by their word eh? But now that you mention that. Would allowing fewer peers just mean fewer people/transactions will be using your node to verify transactions? What is the number of peers set to by default, and what would one set it to, to lessen the hit on data? What did this lad in your example end up having to set it to?

FWIW, ISP may play dirty by claiming "no data caps", while also stating "acceptable use" or "fair usage policy" on their ToS or disclaimer page. If your data usage exceed that, your internet connection would be slowed down or you'll receive warning email/letter.

What about Monero. I tested it.

And I can't remember the outcome.
What about Monero? And what do you mean by you tested it and cannot remember the outcome. You can surely convert your BTC to Monero in a p2p exchange, move it around and send it back into a different p2p exchange, then convert it into BTC and send it in bits to different BTC addresses. It is a good method of privacy when done correctly. I can see the feedback on your profile, so i think you should start making your posts make meaning.

While it's possible, it's weird there aren't many post which mention the cost. P2P exchange may offer bad exchange rate due to low volume. There's also fee when using P2P and creating on-chain TX which could be costly on specific condition.

OP, i saw your other thread which promote certain service. If you ask this question because you want accept Bitcoin on that service, there are things you should consider.
1. If you only care about convenience and don't mind 3rd party hold the coin, most cryptocurrency payment gateway should do the task.
2. If you want to hold received coin, use something like Coinbase Commerce where you only share your master public key or address with them.
3. If you want to self-host/self-manage the Bitcoin payment gateway, consider BTCPay.

When I transfer off of a CEX and onto my Cold Card, the private node wouldn't benefit me at all either would it? Seems you'd only get the transactional privacy of a private node when sending out of your wallet via sparrow, correct?

Even if you use CEX, using private full node still prevent random server (which used to obtain relevant TX) to know list of your addresses.

Also, I notice a lot of the nodes are utilizing an .onion address for added privacy. Is this also something one would suggest? How difficult is it to setup an tor server, and is that even worth doing on a non-server environment PC? I'm not typically one to use things like VPN's, or TOR browsers for privacy as I don't really care who knows what YT videos I'm watching, or what games I'm playing (This is a gaming rig, if that's worth mentioning), but if setting up a TOR server to run the node on a .onion address isn't too difficult to do, and won't affect my internet speeds, then I'd be open to learning that.

Unless your country or ISP intentionally block Tor, it's not that hard. Bitcoin Core provide guide to use Tor which can be seen on https://github.com/bitcoin/bitcoin/blob/master/doc/tor.md.

We added Two-Factor Authentication (2FA) in our new release for more protection!
You can download the new version and read more on our website. https://gingerwallet.io

Can you explain more how the 2FA works? I've read the FAQ just now and it seems the user depends on your server to obtain encryption key which used to encrypt/decrypt user's wallet files. If my understand is correct, what would happen if user lose access to their 2FA or your server isn't accessible?

Yes, that's right, the server stores an encryption key. If the 2fa server is not available, the wallet is not available. The user can reset it with the original 12 seed word and password.
This is inconvenient, but still better than someone getting the unencrypted file and keylogging the password (unfortunately we know of such a case).

I see. I only can hope those who use that feature backup their 12 seed words and password properly. Although by doing that, user would lose label on their TX or UTXO which could lead to worsening privacy.

--snip--
Why does a wallet need 2FA?

It sounds like an implementation similar to Electrum x TrustedCoin, otherwise this makes no sense. Ginger wallet's website doesn't have a registration system.

I have no knowledge of the Electrumos method of implantation, so I have no basis for comparison. Ginger has no registration. The "user id", if you can call it that, is contained in 2fa_info.gws, a completely random sequence of bytes, generated during 2fa registration on the server side. It cannot and does not store any user information. If I want to simplify it a lot, all that happens is that the server responds to a fixed random byte sequence (clientserverid) with another one (wallet encyption key).

Your and Electrum 2FA works differently. Electrum 2FA refers to 2-of-3 multi-sig wallet, where user provide correct 2FA to get his TX signed. In case the user lose 2FA or TrustedCoin not available, he can use seed words which contain 2 master private keys.

It's very probably scam, so i left a negative tag to OP. It's annoying to see scam attempt, but at least it's obvious ones where they don't put much effort into writing. Aside from OP don't know about paragraph, FAQ on their website shows lorem ipsum and doesn't even talk about cryptocurrency recovery.

I don't plan to use your service, but the idea behind of your service is rather cool and practical. I also briefly read the FAQ, but it seems to be unfinished. For example,

1. These FAQ contain link which leads to "404 Page not found"

What are the benefits of using Archway?

With Archway you can accept global payments without restrictions, get paid faster (within 48 hours or less), and save with some of the lowest fees in the market (only 2%)! To learn more go to: ​​https://archway.finance/for-contractors

How do I sign up?

Happy to have you join us! Smiley  Please go to https://archway.finance/join

2. Another FAQ mention you're registered on EU, but there's no additional detail. I tried searching your company using https://e-justice.europa.eu/489/EN/business_registers__search_for_a_company_in_the_eu with keyword "Archday" on "Company name" column and selecting all country, but there are 184 results.
71  Bitcoin / Bitcoin Discussion / Re: Is bitcoin mining still profitable? on: September 05, 2024, 10:59:39 AM

I’ve really many equipment since I was mining ETH back in 2021 but when it changed from PoW to PoS I’m not sure about its profitability..I mean only 3% APR and much more money to invest now.
And i'm not aware of any coin which offer 150% APR by perform staking.

I believe I saw new projects who gives that like ETH in the beginning

Assuming you remember it correctly, such APR probably only offered for very limited quantity or duration. And if you'd rather buy and stake altcoin, you might want to visit https://www.stakingrewards.com/assets which shows APY of such altcoins.

Without any detail, no one can make solid recommendation. But if you don't have way to obtain Bitcoin ASIC affordably or cheap electricity price ($0.07/kWh or lower), BTC mining probably would be unprofitable for you.

Make it 5 cents or lower, 7 cents before taxes and other costs is a no-go, even with the s21 launched 6 months ago you're looking at 3 years' ROI.

You're right. I'm not mining, so i don't always remember the suitable electricity price.

 I can post TXID of  all doge transaction and purchase date of my sister new nano x, And even share 24 seeds here since I dont use them as proof.
People here can believe me or not, up to you.

FWIW, it could harm your sister's privacy. In addition, there's no way for us to verify whether her Ledger Nano S actually generate the 24 words.

3% APR is current rate of ETH staking. Few years ago, it was few times higher.

So, do you recommend to stick to BTC mining or switch to staking? I saw crazy APRs like 150% but not sure about it

Without any detail, no one can make solid recommendation. But if you don't have way to obtain Bitcoin ASIC affordably or cheap electricity price ($0.07/kWh or lower), BTC mining probably would be unprofitable for you. And i'm not aware of any coin which offer 150% APR by perform staking.
74  Other / Politics & Society / Re: Harris campaign now accepts Bitcoin on: September 05, 2024, 09:21:42 AM
Some media and people misunderstood earlier news, where CoinBase decided to make clarification as reported by CoinDesk.

Kamala Harris Is Not Directly Accepting Crypto Donations, a PAC Is, Coinbase Says

A spokesperson for Coinbase said the Future Forward PAC, which is dedicated to supporting Kamala Harris, is accepting crypto donations, rather than her campaign directly.

--snip--



The linked article cires that a Political Action Committee (PAC) called "Future Forward" which supports the Democratic Party and presidential nominee Kalama Harris, are the ones who are accepting cryptocurrency donations. This should not be confused as the party or campaign itself is accepting cryptocurrency donations. A PAC is essentially a tax exempt organisation which can support political parties. The PAC's choice to accept cryptocurrency does not represent the Democratic parties beliefs or support for cryptocurrency.

It's good to see someone read the news carefully. And OP's title isn't accurate, it shows that some cryptocurrency user/company doesn't support or trust Trump.

I wonder if it is just me or has anyone else thought whether these vulnerabilities have already been used for a long time before being exposed?

Nobody knows for sure. But if it was widely used by criminal, we would find such news or report.

What I am wondering is.  Was I safer during this Exploit as a Non Java Script user?

Safer? Yes. But not all vulnerability related with JavaScript. For example, https://www.mozilla.org/en-US/security/advisories/mfsa2022-28/ shows some which doesn't use JS.
76  Economy / Service Discussion / Re: YubiKeys - valnerable to cloning attacks on: September 05, 2024, 08:37:39 AM
it does take quite a bit of sophistication and hardware so hopefully not widespread issue.
I don't know how complicated this is but I suspect many of this encryption algorithms have backdoor in them.
This could also affect more devices and maybe even some hardware wallets that have support for FIDO like ledger, trezor and maybe few others.
Another warning is that Optiga Trust M chip that is used in new Trezor Safe devices could also be affected, according to this artcile!

Quote
SLE78 made by Infineon and successor microcontrollers known as the Infineon Optiga Trust M and the Infineon Optiga TPM. The researchers suspect that any device using any of these three microcontrollers and the Infineon cryptographic library contains the same vulnerability.
https://arstechnica.com/security/2024/09/yubikeys-are-vulnerable-to-cloning-attacks-thanks-to-newly-discovered-side-channel/

It's probably worth to mention this isn't first time such vulnerabity discovered on Infineon product. Few examples,
https://www.infosecglobal.com/news/infineon-vulnerability
https://www.zdnet.com/article/tpm-fail-vulnerabilities-impact-tpm-chips-in-desktops-laptops-servers/

A bit concerning, since few cryptocurrency wallet also support YubiKey these days. The news only mention someone who targeted by nation-states should be worried, although people who tons of assets/money using YubiKey probably should also be more careful.

Why are people using their hardware wallets as 2FA devices??

It makes no sense. It breaks all the laws of wallet security. You should *never* be plugging your hardware wallet into your computer just to authenticate some random websites in your browser, that makes it no more secure than Web3 Connect (spoiler alert - that's how a lot of scams are done nowadays).

Get a separate device to use for 2FA.

I would expect some people assume it's much harder or practically impossible to steal their coin or other private data just by plugging their hardware wallet for a while.

Your FAQ also doesn't mention anything about shipping or potential custom fee on buyer's country, so you probably need to update it. And while i know few people do "medical tourism" where they visit hospital and buy medicine, i haven't see anyone buy medicine from online shop not located on country where they live.

I'm not sure what's the best thread, so I'll just post it here: testnet3's mempool is currently empty. For the past months, mempool was full and fees where high. It looks like the "data spam" suddenly stopped, while ASIC miners and "20 minute miners" have halved the block time.

Weird, since yesterday testnet3 was busy where mempool.space recommend over 500 sat/vB for high priority TX. I wonder if most ordinal/rune created on testnet3 no longer have value.

Amazingly, that means testnet3 can now actually be used again for testing Smiley

Although i wonder how easy is it to obtain testnet3 coins now (aside from mining). Tesnet faucet was abused on many occurrence.

Since you ask this question on Bitcoin forum, i expect most of miner here would stick to Bitcoin. Although you can use website such as https://whattomine.com/asic to compare profit between coins using same algorithm.
