Nein, das geht nicht.
Ein public key ist 256 bit groß. Wenn die Hälfte bekannt ist, fehlen immer noch 128 bit. Die kann man nicht erraten / bruteforcen.

Wenn man jedoch die halbe Adresse zur Verfügung hat, sieht das anders aus.
Dann könnte man die ganze Blockchain parsen und nach Adressen suchen bei denen die bekannte Hälfte übereinstimmt. Es würde mich wundern, wenn da mehr als eine dabei rauskommen würde.


Also, mit public key -> geht nicht, da man 128 bit bruteforcen müsste.
Mit Adresse -> geht, da es vermutlich keine 2 bereits benutzten gibt bei denen 50% übereinstimmt.

Wieso sollte man das auf einem Raspberry Pi nicht zum laufen bekommen ?

Bei mir läuft ein Webserver auf meinem Raspberry Pi.
Darauf läuft eine anonmy suchmaschine, welche das ganze Tracking-zeugs abschneided und mir schöne Ergebnisse von mehreren Suchmaschinen liefert, eine self-hosted Cloud, Markdown editor, Webmail (als Interface für meinen mail-server) und vieles mehr.

Und das ganze zieht dann ca. 5€ Strom jährlich.

So ein Faucet collector sollte überhaupt kein Problem für einen Pi darstellen.

Fast alle Wallets sind HD-wallets (Hierarchical Deterministic). Das bedeutet, dass sie die private keys von einem Seed ableiten.
Der public key wird von dem private key abgeleitet. Und die Adresse wird vom public key abgeleitet.

Da man quasi unzählige private keys (und desshalb auch Adressen) generieren kann, wird für jede Transaktion eine neue generiert. Dies dient der Privatsphäre.
Die Adressen an sich sind 'ewig' gültig. Du kannst also immer Coins an und von dieser Adresse senden, solange du den private key hast (was der Fall ist, fall du ein Backup - also den mnemonic code - hast).

Mit dem public- und private key kommst du eig. garnicht in Berührung. Das regelt die Software im Hintergrund.



Jaxx ist meines Wissens nach ein Desktop- bzw. Mobile wallet. Kein online Wallet.
Aber definitiv nicht zu empfehlen. Ich würde jedem von Jaxx und Exodus abraten.

The developers are at fault that you have fallen for a phishing message ?
It is stated on the website (and on this forum and almost everywhere on the internet) that you need to verify the signature to make sure you are using the original software.

I am sorry to say, but only you are at fault. No one else.




So you were storing all of your coins on a wallet shared between your computer and your mobile phone ?

It seems you need to reconsider how you store your coins. Try to acquire knowledge regarding secure storage of sensitive information. This forum is a good place to do so.
If the sum was really big, why did you store it on a computer which is connected to the internet, shared with your mobile phone  Why no hardware- or paper wallet ?




Verifying the signature is common sense if you spend at least half an hour reading about securing funds.




Just read what the website says and follow. Verify the signature and don't click on any link you see. As easy as that.

0 valuable content from you combined with plagiarism.. does not look good for you.


Well.. that would be another reason to NOT unban you.

Why should you be allowed to break the rules without even having the intention to contribute to this forum ?
The only thing you want is to participate in bounties to earn a few bucks.


So.. lets summarize:

• You brought no value to this forum
• You broke the rules by plagiarizing
• You don't intend to contribute to this forum in the future
• You just want to earn a few bucks

Do you really think this appeal will be successful ?

This is done to protect the network against spending coins which do not exist due to forks.
It does not protect the coinbase transaction itself in any way.




I never heard the term 'virgin bitcoins'.

The first transaction of a block indeed is the coinbase transaction and is composed of the block reward and the fees.
The exchange coinbase.com has chosen that name because of the term.

IMO those applications can indeed be used decentralized.
The supply chain, for example.

You would be able to track the harvesting of the cottage, the transport via ships, the creation of yarn and finally the manufacturing of a shirt completely transparent.
There are multiple entities involved in such a process. And with a blockchain tracking all of these steps, there would basically be no central authority.


Yet, there is not a single project which does that.
Anything one can find at the moment, indeed just uses blockchain as a buzzword. But i am confident that we can have several applications backed by a blockchain in the future which have absolutely nothing to do with cryptocurrencies.

I'd say not a single of the mentioned applications needs bitcoin at all.
That actually was the point - to have applications for a blockchain excluding cryptocurrencies.


Just because centralized databases are better at some points, this doesn't mean that they should be used for all of those applications.
One could say the same about bitcoin. Why use a blockchain if you can use a bank ?

The trustless and decentralized aspect is what makes it special. And this can also be desired in a supply chain, identity management, IoT, etc..

I'd always advise to create a paper wallet by generating the private keys yourself.
Then choose some good-looking template and print your keys onto that.

That is generally more secure (if you use a proper wallet, what core definitely is) compared to using some online site to generate them.
Even when downloading the website, you can never be sure of what and how it is doing what it is supposed to do.


P.s. There is more to be done to create a secure paper wallet than just using the correct way to generate the private keys. Make sure you know how to do it safely before actually creating one.

There are multiple real word applications for a blockchain besides cryptocurrencies. Crypto's are just one of a lot applications.
It can be used wherever a trustless decentralized storage is desired.

Some applications would be:

• Supply chain
• Digital Identity
• Data management between organizations
• Patient chart
• IoT
• Real Estate

Define efficiency.
Do you have a better approach for a trustless decentralized data storage ?

Do you really need a graphical session ?

The best way would be to simply SSH into your server. And if you really need to run some graphical application, enable X11 forwarding (-X parameter).

If you are not heavily coding on your remote server, a simple ssh connection without X11 forwarding should be the fastest possibility.
And if you are coding a lot, another option would be to have a SSH session open, code on your main machine and just copy it over via ssh (scp). That's just one command, and it would be in your history of the remote machine. So not a lot of additional work.

"AutoReply" might be not the best suited name.

What the script actually does is to check the threads you provide and bump them if the requirements allow it (i.e. 24 hours have passed).
This is not meant to be used to participate in discussions or to spam random topics, but to bump your own topics (e.g. offering service) for more visibility while not breaking the forum rules and having the least amount of work.

It is more an "AutoBump" script, than "AutoReply".

Increasing the blocksize has nothing to do with scaling.

I mean.. of course you could increase the blocksize and accept all the downsides with it. But you won't solve any problems with it.
You will be confronted with the same issue again in X years. And what are you going to do then ? Increase it again ? To have even more negative effects ?

Relying on a bigger blocksize in order to scale for more transactions is a bad approach. What we need is real scaling, not postponing the problem while accepting negative effects.
There are much better approaches than the blocksize increase.

You always have this 'trust issue' when accepting payments. All BTC transactions are irreversible.

Using a single address for multiple clients is discouraged, because you won't be able to determine from which client you just received the transaction.
A simple - but still effective - way would be to derive a new address for each customer using a master public key.

But you'd still need some way of checking whether you just received the transaction (and the correct amount). While it might be possible to be done by hand, that's extremely time-consuming.
You'd need to automate that, and that's what this thread is about.

Given the fact, that it is a cold storage (i.e. air-gapped computer), yes. There is practically no additional risk in the given scenario.




My whole statement was referring to your scenario:



As far as i can see:

• Offline computer (air-gapped)
• Encrypted hard drive

And with that, it doesn't matter if you have a text file containing the private keys / mnemonic code on this computer.
The wallet file itself is also stored there, containing this secret.




Sure, but same applies to just a wallet file being stored there.
I don't see a practical scenario where a digital backup increases the risks (given that scenario with offline-storage and encrypted hard drive).

But this wouldn't be too much of an issue either.

If the computer is air-gapped and the hard drive is encrypted, storing the seed on the hard drive would not decrease the security at all.

I agree that a digital backup should never be the only backup (in case of electronic devices breaking).
But the digital backup itself should no be a problem at all.

If the computer is turned off, no information can be extracted (encrypted hard drive).
If the computer is turned on, information can be extracted from the backup file AND the wallet (so no difference either).

As long as the computer is air-gapped and the harddrive is encrypted, that would be fine.


Or which situation can you think of where the digital backup would reveal the seed while the wallet file wouldn't ? ?

A large percentage ?

Current hashrate of BTC: ~ 78 EH/s
Current hashrate of BCH: ~ 2 EH/s

A small percentage decided to support BCH, instead of BTC (including segwit).




It is consensus.
Just because a very small minority decided to do something else, it doesn't mean that no majority was achieved.




Not really, the difference is marginal.
BCH's hashrate currently is roughly 2.5% of BTC's. This doesn't influence the security/strength of BTC at all.

Do you know how much people have complained about electrum already ? Countless..
Do you regard electrum as not being safe too ?

I do not agree with any kind of paper wallet creation through websites (regardless whether online or offline). But without proper evidence, or at least some indications, calling a random paper wallet website not safe is not completely correct.
No website is safe for newbies. No web wallet is. And no desktop wallet is.
Nothing is safe for a user without common sense. Not even a hardware wallet.

Are there any indications why this website should be avoided (besides newbies complaining about it) ?

So, your devices got compromised and you lost access to your mail account.

How is this related to you losing BTC ? Did you store your private keys / mnemonic code via email ? That would be a huge blunder.
Or how could it be related to your mail account ? I assume you didn't use a proper wallet ?

Anyway, you should make sure that your devices are no longer compromised. Somehow an attacker gained access to your passwords and obviously also your device. Make sure to format any drive and reinstall an OS.
I guess you already changed all passwords (from a clean device) ?

A wallet file does contain private keys.
You can not use a wallet without the private keys.

One can either choose to not store them on a computer at all, which means you need to import them at some point to access the coins, or you store them on a computer.
Since the computer would be offline anyway, it doesn't really matter whether you store them on it, or not. You don't gain much (if anything at all) security-wise when not storing them on your fully offline pc.
