you guys are funny I come with a specific question but you can't help to assume and judge not even answering

I feel sorry for you eckmar, I answered all your questions and you still can't get a clue or pass your own mental restrictions
You legendary badge won't protect from ridicule lol

I erased some answers because otherwise the idea isn't patentable and I  just want someone to build it

sorry I was contacted by people interested to produce this device and for now they want me to erase all my answers

You know what you can develop is something that Encrypt the Private Key when you have to "sweep" it from your Paper wallet to your desktop wallet.  Wink  It will be nice if someone will not be able to keylog your Private key, when you are in the process to sweep it from cold storage to your Paper Wallet.

So you can go offline when you "Copy" the Private Key, then this software encrypts it and then you go online again and it is in memory in a encrypted format and once you logged into your Online wallet and you Paste it.. it will decrypt it and insert it in the field to sweep the wallet.  Wink

It is always stressful when you have to sweep a wallet and you do not know if it can be intercepted before you are able to sweep it.  Roll Eyes

I guess it'd be safer to automatically/manually generate encrypted private keys which can be decrypted with keys you previously generated to use for safe decryption of all your future private keys that are encrypted.
You get the encrypted private keys and decrypt them automatically/manually on very secure devices or on secure physical environments.

This ^ is recommended on well decentralized system (on full node) so that no one ever knows your decryption keys

I think you missed the suggestion that I made...

What I would like to see ..is some kind of method that will enable you to transfer a "Private Key" in a encrypted state, from say a air-gapped computer or a Paper wallet to a online wallet. So you generate or scan the "Private Key" on another "offline" computer and then you encrypt that key ..before you transfer it to the online wallet.

So when you paste that information in the "Private Key" field, you press a combination of keys and it will automatically decrypt it and you can simply press enter to sweep the wallet to the online wallet. (Example : Electrum)  Wink


I thought that sweeping private keys meant you sign a transaction that sends all your coins to a new address. Which is safe.

Sending a private key, or even have it on my screen is way to risky for me. But if you had to send something secret , like a key, to an online wallet then this wallet should provide their public key so you can have a secure communication.

I don't think that using any device is needed in this case and there are already some software solutions that encrypt anything you type with your keyboard.
Some of them are included in various antivirus packages and there are separate software options like Ghostpress for example, and for Wireless keyboards there are AES encrypted devices.
Using on-screen virtual keyboards like Oxynger KeyShield or something similar also help to protect from different keylogger attacks.

It's for those who don't feel secure about their computers (travelers, paranoiacs...) or need to be 100% sure nobody can read their messages.

...

Lets take AES256 as an example. It can encrypt 256 bytes of data at a time, which translates to 64 characters. But the problem with deferring the encryption until the 64th, or generally the Nth, character is:

1) if you do, then the user will not see any of their input until after the Nth character is typed and they're all encrypted at once. This also introduces a problem of "what if N characters are never typed but less than that, should user feedback wait forever?"
2) if you don't and you just pass the N-1 characters to the user before encrypting them all at once on the Nth char, then those characters may have been intercepted by another listening program.
...

Your keyboard sends a signal to your CPU when a key is pressed. This signal is processed as an interrupt which means the processor stops everything it's doing and reads the character from the keyboard. All of this is programmed in the code of the operating system you are running, in assembly language. It's not possible to encrypt anything while this assembly code is running because such functions do not exist in assembly.

There is nothing stopping someone from placing assembly code in that position to read the characters to their own memory.


the device is between the keyboard and the computer

you seem to assume how it works

you could just encrypt the whole message in the device and then send the encrypted message but it would not allow you to fill forms or to chat online

The recipient can read the  original message.
Without the need for a device to decrypt it?

You need the a device to decrypt it. You would copy the text and the device would read it. You would read the unencrypted text on the device's screen

I don't know if people would be it interested.
It depends on a lot of things...
e.g. Open-source software, the whole process itself [for consumers], how that device is going to look, its price, and a few other things.

Personally, I'm not going to use something like that on my main computer, unless I fully trust the provider/manufacturer, but I'd probably buy one to test for fun [If the price is right].

I don't want to lose my time building something people won't buy.
How much you think that device is going to cost for potential buyers out there?
I would compare it to the price of a raspberry pi plus the cable and the screen.

Are you talking about a new account you created?

Possibly you have evil IP. There is a fee to pay for it to whitelist the IP.

Could something be done to use the site using Tor?
There is a special link which will allow you to bypass the anoying captcha. You will find it once you visit this URL: https://bitcointalk.org/captcha_code.php

yes!



I tried registering with Tor and it took me half an hour to complete all Captcha. Then it said I couldn't post.

I was in the same boat as yourself Borilla because I've registered using my (paid) VPN provider. Since this is a shared IP probably it ended up in a "evil list" as Royse777 rightfully said.

In my case I had to pay a small BTC fee to an address that I got whenever I logged in. You basically can't do anything until you pay your fee to the address provided. Upon paying if you wait a while the account will automatically be allowed to post/make threads.

Don't be like myself who waited almost 3 years to activate his account ... ((bells) Shame on me (bells)

I was trying to create a new , more secure, account.

Are you talking about signing a transaction?


- How bitcoin nodes communicate

No, signing your message. If you're a node, how to be sure you're receiving a message from a certain node and not from a hacker who fakes being this node?
11  Bitcoin / Development & Technical Discussion / Re: Can nodes be sure who they receive messages from? on: November 24, 2019, 09:56:45 PM
It's not very clear. In your link it says nodes can use TOR. But here https://en.bitcoinwiki.org/wiki/Network it says you know the IP addresses of all your peers.

In your link, at the beginning it says "At the moment, we know about 10,000 nodes that use standard ports and do not try to hide the fact of their existence, so they are easily detected by others. The number of nodes, the access to which is closed, this value exceeds by 5-6 times."  This seems to be what I try to understand but it's not understandable. Does it mean there are 10,000 non hidden nodes and 50,000-60,000 hidden ones?

From these two links I'm guessing, nodes are "defined" by their IP addresses or TOR exit addresses, i.e., if you change your address  you have to join the network again from start. Right?


Someone malevolent with the list of the nodes addresses could easily attack the network then, no?


I was dreaming of an anonymous decentralized-changeable  and trust-less network. It must be possible though... 




12  Bitcoin / Development & Technical Discussion / Can nodes be sure who they receive messages from? on: November 24, 2019, 08:50:23 PM
I know blockchain but I'm really a noob for all internet techs.
My question is simple but not too simple to put in words. Can nodes communicate between each others so they know for sure who they receive message from if the sender wants to be known? (I add the "if the sender..." because theoretically nodes could hide themselves and send anonymously)
Can a node require other nodes to sign their messages. Do they actually do it?
Do they use another technique than signing to be sure who they're communicating with? like I send a code to the address of a node and this node as to send the code back with its message.

If someone malevolent attacks all the nodes at ounce by sending many messages to the nodes.  Would they need to all change their addresses and find each other again?

It's not so easy. You can bank in Montenegro like I do (no AEOI), but very few exchanges will wire money there. And you can't use an intermediary like Transferwise or Payoneer.

I would be interested to know the name(s) of the(se) bank(s) there and these exchanges if you have. You can write me in private if you prefer. Thanks
14  Other / Politics & Society / Re: Countries where you can easily open a bank account and cash out your crypto on: February 19, 2019, 04:24:25 PM
This is always the same question but I haven't read a satisfying complete answer. Most article or blogs put a list of countries with no real experience or research done.
Let's say I am non American, I travel most of the year, I might be a citizen of an EU country. I 'm looking for a country where I can open a secure  bank account and send money from a crypto exchange with no hassle.
Theory is good but personal experience is better

I'll guess it's for tax evasion purposes.

First thing first don't bother if you use an exchange. Exchanges need your ID and governments are working with exchanges. Especially in EU.

So your government won't find your bank account if you go in a tax paradize but they'll find your exchange account. And that's basically the same.

What country are you from exactly?

It's not tax evasion.
Also in some EU's countries you pay tax only when you cash out, and in others you don't even pay tax on crypto.

Obviously I am asking for something legal and secure.

If your friend was proxybanned on registration (it should load up a page with all the details; can't really miss it), he can bypass said ban by paying the fee. If that's not the case and the ban message is a standard one, your friend probably wasn't banned for using TOR but rather for breaking the rules. I've never seen anyone getting banned on Bitcointalk for using TOR (aside from the bypassable proxy ban on registration).

If it's neither, post a link to your friends profile and I'll check it out.

Edit: AdolfinWolf beat me to it and summed it up pretty well. Alex_Sr suggestion is useful if you don't want to keep filling captchas every time you try to log into the site.

Yes he had to pay this fee.

So if I understand you can register with TOR and then use the bypass link to login from anywhere
16  Other / Meta / Re: Impossible to login via TOR on: February 19, 2019, 04:10:48 PM
My friend's account got banned because he tried to log in via TOR
I'm assuming you're talking about a brand-new account?

Probably because the exit node he was using was abused by someone else already, in which case he needs to pay an "evil-"ip"" fee. https://bitcointalk.org/index.php?topic=1215937.0
https://bitcointalk.org/index.php?topic=711968.msg8044683#msg8044683


If he was using an account which already made posts, i can assure you, his ban is not from logging in through tor.


Ok. So he wasn't lucky and should try with another exit node...
Thanks

My friend's account got banned because he tried to log in via TOR
Also it was a hell to register (went through tens of stupid captcha)

And what prevents once generate Captcha bypass code and forget about the captcha?
https://bitcointalk.org/captcha_code.php

I am not sure I understand your answer.

Once you are registered you have your own bypass link, right?
But my friend was asked to pay just after registering to "prove" he was not a hacker. Because his TOR exit node had been recognized.

The algo considers book data (not last pricer).
So if i take a pair on two exchanges adding diagonal percentages and subtracting non-diagonal ones should give zero.

Will you add EToro?
