It's even better if you choose non custodial and open source wallet with decent reputation.


Ask them how long you'll need to wait until the "issue" resolved, IMO they expect you'll forget about the issue soon by giving vague answer.

You could abuse comment field in payRequest to send small amount of data. But both peer must explicitly enable comment field and it's limited by 2000 character on the URL (which also contain payment information), so it's more practical to use comment field to send notes/download link instead.

I don't disagree with your statement, but it's like comparing apples with oranges. Bitcoin is cryptocurrency while GoFundMe is crowdfunding platform. They could suffer from similar fate as long as they rely on centralized service (e.g. BitPay).

Thanks for the information. While it's better than no backup, another problem is "Previous Version" use low percentage of partition space. If the partition space is really small and user frequently write files, it's possible Electrum wallet files won't be or less frequently backed up.

Exact hardware (CPU brand, CPU type, etc.)? I doubt it. But we do know some Bitcoin nodes run on VPS. It's indicated by Bitcoin node IP which is in IP range of certain VPS provider. Those VPS provider usually state their hardware specification, so you could get minimum number of node which use modern Intel/AMD CPU.

Depending on your end goal, contribute to or privately modify existing open-source wallet should be better option since you could reuse existing component and avoid create new/re-implement existing standard.

Another service that i know is https://ramp.network/. There are multiple ways to integrate it with your website/application, but there's easy way by adding 1 HTML tag (https://docs.ramp.network/web/quick-start-hosted/).

P.S. i never use this service, so you should additional research (such as their ToS).

How about this?



Why not? It's most practical option if you're not cryptography/math expert.

While i agree with your statement, very few ASIC-resistant perform good enough. For example, developing Ethash ASIC took long time and it's efficiency isn't very big against GPU (if you compare efficiency between GPU and ASIC with different ASIC-resistant algorithm). RandomX also looks promising, but time will tell how well it perform.


As long as there's multiple competitor on SHA-256 ASIC, i would say no.

And that's why you shouldn't run random application/script you found on internet, even if you use Linux.


Application with lots of dependency also risky, i expect someone will try to perform supply chain attack on programming library.

Thanks for your effort, i appreciate it. But it's almost 3 times of original, no wonder they require you to sign up to see the spec/price. There's better alternative such as SporeStack (https://sporestack.com) which is accountless and cheaper.

According to Wikipedia, RTX 3080 Ti and RTX 3090 have very similar TFLOPs. So it should be cheaper to rent 3080 Ti where you could reduce the cost up to 25% (rough estimation).



I expect you'll need to register to many GPU renting marketplace and VPS provider. But VPS provider usually offer enterprise GPU instead (such as A5000) which is far more expensive.

I saw the note, but it doesn't say anything about active account which never/almost never receive merit. But i trust you'll ignore vote from obvious abuser.

Your VPS is far more expensive than most popular VPS provider (such as Linode). With those price, i could find different VPS provider (which accept BTC) with better privacy policy or better specification. Additionally, you linux image is a bit outdated, i couldn't find Debian 10 or Ubuntu 20.04 LTS. I would advice you to take more time to setup your service before announce/promote your service.

What you need isn't Tails which specifically designed as live OS. You should check different linux-distro such as Whonix and Qubes. For Whonix, you can check this guide https://www.whonix.org/wiki/Bitcoin_Core.

If you're willing to try newer linux distro, check Created a Hardened Linux OS for Crypto Hodlers.


It's should possible with "hack" like this, https://www.howtogeek.com/50786/using-srvstart-to-run-any-application-as-a-windows-service/.

Stackoverflow is great place for technical question/problem, but it's not meant for casual discussion.


Bitcointalk is centralized, so it's possible this forum going offline.

I didn't expect someone would review $299 device (excluding possible import tax and shipping cost). But with such high cost, i'm really annoyed they don't bother include rechargeable lithium AAA when they include industrial class microSD.


IMHO, if people choose FE rather than other hardware wallet (such as Ledger and Trezor) which is cheaper and easier to use, it's more likely they have better secure practice. I wouldn't worry about malicious application which replace PBST file if you perform good security practice and verify the transaction before sign/broadcast process.


I doubt it's easy to lower the price when it's still assembled in U.S which have high wage cost.

I agree it's not needed to change SHA-256 and it'd be great to reduce dominance of centralized pool. However, i'm not talking about changing SHA-256, but running 2 algorithm together since i assumed that's what @itel meant.

Their GitHub repository[1] also contains lots of resource (mostly PDF slide and video). But personally i only check concept PDF slide[2] and part of their FAQ[3]

[1] https://github.com/LNP-BP/presentations
[2] https://github.com/LNP-BP/FAQ/blob/master/Presentation%20slides/RGB%20%26%20Spectrum%20explanation%20for%20business.pdf
[3] https://www.rgbfaq.com/


While there are many parts i don't understand, there are few over-estimated promises/offer. For example (on concept PDF slide page 13),
1. Zero storage cost is simply impossible when you utilize Bitcoin blockchain (to store the smart contract state).
2. Extreme scalability is limited by Bitcoin network and Lightning Network channel/routing.

Talking about impact, it heavily depends on availability of user-friendly software which support RGB (and related protocol such as Spectrum). But assuming it's available, IMO it has similar impact with LN.

First of all, how would consensus work when are 2 different PoW (SHA-256 and other algorithm for CPU) on the network?


Even without ASIC, someone could simply build CPU farm (just like miner build GPU farm). Besides, used CPU/server rack sometimes could be found really cheap on online shop.
