2361  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][NEW][ICO] Hydrogeno - Building a sustainable future on: August 07, 2019, 01:16:27 PM
Caution!

The whitepaper is was plagiarized (https://bitcointalk.org/index.php?topic=5171144.0).

The original account is Hydrogeno (Flag open + negative trust).

Creating a new account just to not have the negative ratings + flag displayed is shady as hell.

Be careful when investing into this project.

But it appears to me like 99% are drawing the lines like it HAS to go up, when in my opinion there is also a significant chance of btc actually not going up!

Well yes.. almost all 'analysts' are just people who have fun drawing some lines.
BTC could pump to 100k$ within a month, but it could also drop to 100$ in the same timeframe.

The probability for both is pretty low, but still possible tho.



Also, while FIAT currency could be created out of thin air, the currency in my coutnry has nearly 0 inflation in the last 10 years and thus is really stable

And which currency is that ?

I am not aware of a single FIAT currency with almost 0 inflation within the last 10 years.



So the fiat system seems to work really well in the real world?

Well.. the average lifespan of a FIAT currency is 27 years.
And this fact doesn't sound very satisfying to me.

Okay good find unless there are no exceptional explanation from the users like: they are brother, sister or friends etc.

I think the phrase you were looking for is cheap excuseGrin



Not sure what to do. Do we tag them or admin/mod will ban them?

Ban evasion is against the forum rules, so mods should ban him. A negative rating should not be needed in this case.
2364  Economy / Speculation / Re: Alternative view: There is no bull market. Bitcoin will go down. on: August 07, 2019, 12:19:27 PM
So why is it decreasing in mid term and long term (see my chart images)?

BTC price quotes:

01.06.2015: ~230 $
01.06.2016: ~530 $
01.06.2017: ~2.350 $
01.06.2018: ~7.500 $
01.06.2019: ~8.500 $


I don't know man.. doesn't seem like a long term price decrease to me.

Maybe we have different definitions of a price decrease and/or long term ?


You just draw some lines on a chart since the ATH.


I mean.. look, i can draw lines too:




Seems like 1.1k $ in 11/2013 was the highest bitcoin will ever reach. Clear downtrend, don't expect BTC to break 1.1k$ anymore.. oh.. wait.



I think for most investors bitcoin is currently too volatile so they don't invest lot's of money. Also bitcoin is not really backed up by anything and it doesn't pay out dividends.

Same applies to FIAT currencies.
The USD is not backed by anything either.

And both can be created out of thin air without any maximum supply.. oh wait.. this only applies to FIAT currencies  Tongue
2365  Bitcoin / Electrum / Re: Electrum 3.3.4 on: August 07, 2019, 11:15:07 AM
There is no danger in opening of empty wallet and checking old transactions, even if that wallet is fake - what a hacker would steal, transaction history maybe?

In addition to that, it should be clear that every electrum server one is connecting to is able to gather the transaction history too.

I don't know whether electrum saves the last connected server and connects to the same after closing / restarting the application, but i can very well imagine you connect to quite a lot server when using electrum regularly.


@OP:
Just don't freakin install a wallet without properly checking the source of it and without verifying its signature.

Why would you care about a fake phishing message popping up in a fixed version (yes, this has been fixed, and there are countless threads and other sources regarding this topic), if you don't even have any funds on electrum but on your hardware wallet ?

They do not have anything to do with BTC at all.
Those are the ETH-/token- stamps OP was referring to in the initial post:

There is a way to compress random data

No, there isn't.
There is not a single lossless compression algorithm which could efficiently compress random data.

I mean.. of course you could save a few bits or bytes (depending on the size of the file / data), because some iterations might appear in the random data (it is random after all, might appear, might not).
But that's not really compression.


For example, i created a ZIP archive of 10 MB of random data:

Create 10MB of random data:
Code:
dd if=/dev/urandom of=random.data bs=1M count=10

Create a ZIP archive:
Code:
tar czf random.data.zip random.data

Verify the filetype:
Code:
$ file random.data
random.data: data

$ file random.data.zip
random.data.zip: gzip compressed data, last modified: Wed Aug  7 07:40:31 2019, from Unix

Now, compare the size of both files:
Code:
$ du -s random.data
10240   random.data

$ du -s random.data.zip
10244   random.data.zip


As you can see, the zipped ("compressed") file is 4 bytes larger than the original one, because it contains additional information (i.e. "this is a zip archive").


You simply cannot compress random data lossless.
It doesn't matter which algorithm you use. Random data can not be compressed.
2369  Bitcoin / Electrum / Re: missing funds on: August 07, 2019, 07:29:29 AM
You didn't even read my message carefully. The phrase key was written in a pen in a paper notebook!

Yes, BitCryptex already pointed that out.
My mistake that i didn't realize it was a notepad on paper (that's probably the first time i see notepad without meaning the windows-notepad).



Version 3.3.2 of the purse. Downloaded from your official website. Prove that it is not you as the developers stole my money! No one else could access the key phrase except the developer.

That's wrong.

Everyone with access to your computer (theoretically at any time after the installation of your OS) could gain access to your private keys.
The developer do not have any way to access them. This is a fact.

You can continue blaming everyone else. But it would be more helpful for you if you try to find out how someone gained access to your private keys / seed. You are the only one to blame here.
If you don't change your habits and don't make yourself familiar with securing digital information, i can guarantee you that you will lose your coins again if you decide to store them the same way (the actual wallet software doesn't matter).
2370  Bitcoin / Wallet software / Re: Safest cold storage options currently on: August 07, 2019, 07:22:02 AM
The solution to a $5 wrench attack, and other similar attacks involving physical force to you as a person is to keep a small number of coin associated with a BIP 39 seed with the passphrase/last seed word being something different than the passphrase that secures the majority of your coin. This will allow you to give something to the attacker while both preserving a portion of your coin and maintaining your safety.

Well, but this is only possible if either 1) the person attacking you doesn't know the magnitude of BTC's you own or 2) you have an amount large enough accessible without the passphrase.

If an attacker knows (e.g. because you are telling everyone, or because you are some known person in the community) that you own about X - Y bitcoins, he won't be happy with seeing 1/10 X or even less of that in your non-password protected wallet.
I mean.. you might be able to deceive attacker which aren't familiar with BTC and wallets, but in any other case it will be pretty obvious that the full amount is protected with an additional password.

This might be useful for plausible deniability regarding a person which doesn't know how much you own, but it won't protect you if he knows how much approximately own.
2371  Other / Beginners & Help / Re: Different Bitcoin Address Formats on: August 06, 2019, 12:49:21 PM
I still think there should only be 1 SegWit address format, because it further confuse people and adds additional problems when services needs to decide what they are going to support.  Tongue

They just need to support bech32.

P2SH was introduced more than 7 years ago, in 2012. If a service didn't yet implement support for P2SH, you can consider them worthless.
P2WPKH nested into P2SH doesn't play a difference here.
Most (if not all) do support P2SH.

They should just finally update their software to accept bech32 type addresses. They got introduced ~ 1.5 years ago. That's not that new anymore.
2372  Bitcoin / Electrum / Re: passphrases in electrum wallet on: August 06, 2019, 11:39:08 AM
So if I moved my coins to a new bech32 would the recovery seed from the original trezor wallet nolonger work?

It still works.

The mnemonic code is always all you need to recover your private keys.
It is just a different derivation path. Electrum chooses the correct derivation path the moment you are choosing which address type you want to derive from the seed.



Also do you need to be using bech32 to use replace by fee. As I dont see that option in electrum with the p2wpkh-p2sh wallets....

No.

You can activate it by going to 'Tools' -> 'Preferences' -> Tick 'Use Replace-by-Fee'.
But i believe it is activated by default.
2373  Bitcoin / Development & Technical Discussion / Re: Solving the problem of on-chain scaling on: August 06, 2019, 11:05:58 AM
There's limit how much you compress data, especially random ones (without pattern or specific iteration)

There is?

Yes. Compression is not a magic algorithm.

Compression works by removing redundancy of data.

Lets look at the following string for example:
Code:
abcbaaaaaaadbaaaaa

You would compress it roughly like this:
Code:
abcb[7*a]db[5*a]


With random data, you don't have such patterns. And therefore you can't compress much at all (at least not if it isn't an extremely shitty PRNG).
Same applies to encrypted data, because it will look like random data.

By the way, that's also one easy way to find encrypted data. Search a drive for data with high entropy.
If you find very high entropy -> most likely encrypted data.
2374  Bitcoin / Bitcoin Technical Support / Re: What is the difference between Segwit? Native Segwit? Legacy? Which one better? on: August 06, 2019, 10:59:50 AM


This graphics is quite inaccurate.

Quote
... since they almost always start with ...

P2PKH type addresses always start with 1.. and P2SH always start with 3...



Quote
More wallets are beginning to integrate this address format.

P2SH has been here since ( almost) the beginning.
P2SH (and therefore multisig addresses) got introduced 2012.

Each wallet supports these. At least it should if it is considered a somewhat proper wallet.

P2SH is nothing new.
P2WPKH nested into P2SH (nested segwit) is somewhat new, but the addresses are not distinguishable until one has used its private key to create a transaction.


Additionally i am missing a few pros/cons for each type on that graphic.
2375  Bitcoin / Development & Technical Discussion / Re: C R Y P T O S T A M P with BITCOIN (solutions? thoughts & questions) - HELP! on: August 06, 2019, 08:38:33 AM
Hey Bob, the first crypto stamp had two parts.

one side had the design plus a QR code with the public key.

the other side had the private key hidden under a scratch field.

To be honest, it is not so much about the BTC which are stored on the stamp. It is more about the collectible item, getting more support for BTC from
official institutions like the Austrian Post office.

But it was a token on the ethereum blockchain.
And not simply an address owning 0.X ETH (which would be quite senseless IMO).

Those BTC stamps basically would be small paper wallets containing an insignificant amount of BTC ?

I mean.. those stamps would be kind of a gimmick, but far away from the token-stamp. Or am i missing something ?




What do you think, would be the estimated actual costs to fund 1000 adresses with 10K Satoshi?

How can I calculate this?

With 1 input and 1000 outputs, your transaction would be roughly 34000 bytes large.
With 1 sat/B, that would be roughly 4.20 USD in fees.

Whether you are using legacy or segwit doesn't play a role with so many outputs.

You can use this site to calculate transaction fees.



And how can I fund all adresses in one transaction?

This depends on the wallet you are using.
Most wallets have the ability to insert the addresses and amounts in a so-called "pay-to-many" transaction. That's at least the name for it in electrum
2376  Local / Anfänger und Hilfe / Re: Probleme mit Elektrum Wallet on: August 06, 2019, 08:26:02 AM
Dann musst du dir eine neue Wallet mit Electrum anlegen und bei Choose Seed type "legacy" auswählen.

Bevorzugt wäre nested segwit (P2SH) zu wählen.

Legacy ist veraltet (hohe fees, transaction malleability, etc.. ).


@OP
Litebit scheint deren Software seit rund 1,5 jahren nicht mehr auf dem neusten Stand zu sein.
Alte websites/services erkennen (native) segwit Adressen nicht als BTC Adressen.

Beim Eingeben der Adresse prüft der Server ob es sich um eine gültige Adresse handelt. Da es bech32 (startet mit bc1..) "erst" seit rund 1,5 Jahren gibt, wird diese bei vielen (veralteten) Services nicht als valide angesehen.

Erstelle einfach ein neues Wallet in electrum und wähle segwit (P2SH) aus (Adresse startet mit 3..). Diese werden dann überall akzeptiert.
2377  Bitcoin / Development & Technical Discussion / Re: C R Y P T O S T A M P with BITCOIN (solutions? thoughts & questions) - HELP! on: August 06, 2019, 08:17:42 AM
So let us assume I want to create 1000 wallet adresses and send 10K satoshi to them. How would you do this?

You would simply generate 1k private keys, and derive the public keys and addresses out of it and create 1 or multiple pay-to-many transactions with your input and 10k satoshi output for each address.

To create a few thousand addresses, you can either use an own script or a wallet like electrum. Electrum needs roughly 1 second per 1k addresses (depending on your machine).


But the important question is.. what would be the sense of funding the address with 10k satoshi ?
Would you print the public-key or address as QR on the stamp ? This doesn't make a lot of sense to me. What would the owner of the stamp do with it ? Import the private key ?
2378  Bitcoin / Development & Technical Discussion / Re: C R Y P T O S T A M P with BITCOIN (solutions? thoughts & questions) - HELP! on: August 06, 2019, 07:41:32 AM
Ethereum wasn't chosen because the fees are lower or because it is easier to create so many addresses, but because it is a platform to create tokens on it.

The crypto stamp is an ERC-721 token.

You can't really reproduce this with bitcoin.


Regarding your other questions, generating 1k - 1000k addresses shouldn't take too long. A few minutes at maximum.
Depending on the implementation it might or might not save on fees with the lightning network.

How would you want to build it ? If everyone has to open a channel first, your are paying more fees (opening + closing channels = 2 TX instead of simply 1 to fund it).
And additionally the LN is still in beta and shouldn't be used with more funds than you can stand losing.


The way, the cryptostamp has been designed, it is not feasible using the bitcoin network.
2379  Other / Meta / Re: AutoReply v1.0 on: August 06, 2019, 07:22:29 AM
That's what it told me to do, and indeed I did that.

Usually it is not recommended to do that.

Such problems can appear when mixing distribution manager (apt-get) and other tools to update software (in this case pip itself).

Did it say that there is a new version and you should update or that it is mandatory ?


Anyway, i would try to uninstall it and reinstall the package-manager version of pip, and then try it again without updating pip:
Code:
sudo python3 -m pip uninstall pip && sudo apt-get install python3-pip --reinstall

Using python3 -m pip install -r requirements.txt should work afterwards.


By the way, which version of python3 and pip are you using?
Code:
python3 --version && pip3 --version
2380  Other / Meta / Re: AutoReply v1.0 on: August 05, 2019, 01:38:20 PM
What's the output when you run pip3 install -r requirements.txt ?
pip3:
Code:
pip3 install -r requirements.txt 
Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
ImportError: cannot import name 'main'

Did you upgrade pip3 outside of your distributions package manager (i.e. using pip3 --upgrade) ?
That's not really recommended.

If you however still want to use the up-do-date (and not supported by your OS) version of pip, try it with the following command:
Code:
python3 -m pip install -r requirements.txt
