Re: Libra have some problems?

The EU is reacting because they believe the ECB is the only entity allowed to print endless money to pump the markets.

Anyway Libra is Facebook's version of Paypal using blockchain and not a truly decentralized crypto.

I agree with this.

It's interesting to see the contrast between Satoshi's 8 pages where he revolutionized the world and 60 page whitepapers that copy and paste existing research into some technology that probably doesn't need blockchain at all.

Re: Bitcoin 'successfully' transferred to an invalid bitcoin address

This is so unfortunate.

Is there somewhere we can blacklist Bitcoin addresses?

Is there a directory for this sort of thing?
Who is we? Where should they be blacklisted? It wouldn't work anyways. What prevents them from creating a new wallet instantly, change their address and keep stealing people?

Sure, I understand that.

I meant after the hack is done, how do we track where the stolen coins go? Is there a standard way to know "this address has funds that were stolen on mm/yyyy?

Re: John McAfee Says China Zombie is a serious company with serious goals

He's a cryptocurrency supporter and a public figure.
But his shilling for money is disgusting, really. It was fun at some point, but not anymore, not really.
I don't know what he has said or done, but I think that both parts of the "deal" are exaggerating, probably knowing that this means more awareness, after all.
And the coinpedia "news" is so newbish I don't know if it wasn't actually written by the team of that Zombie ICO/IEO/whathever.

McAfee brought lots of attention to cryptos, which is positive.

He's also running for POTUS just to bring publicity to cryptos.

Obviously it's in his own interest to, but it's also in our interest IMO.

Not taking sides here, just mentioning that the good he's done is probably bigger than his mistakes.

How was it ever good? Honest question.

I bought DIM at ICO and I can't seem to see what's good about it.


With lack of activity in this thread to your answer it might be an indication of things to come.

Lots of people are still holding in the hope trying to recover losses but seem to be losing more.

I am sorry to read you got in at the ICO but are not happy with what has happened since. You are not the only one, there are others.

I think my DIM is lost. Honestly.

I wonder if anything got implemented at all in the DIM project.

Re: How to withdraw ETH using public address

Unfortunately if you lost the private keys the ETH is gone.

You can get your public address from the private key, but not the other way around.

Re: Hack any wallet?
by

I thought of something different sometimes ago, that apart from the passphrase, you could try to do some permutations and combinations on the private key of a wallet to generate another address and eventually get a wallet with funds. This is not what i would want to do though, because it's as good as saying that such person is a scammer, because you are looking forth to rip from where you did not sow.

My intention is also not to hack anyone. Just a curiosity.

One thing I saw a lot of people get wrong in this thread: wallets come with a predefined set of words. It's not random words from the dictionary. The words you can use are actually limited. Just look at the source code for popular wallets and you'll find a file like words.txt or something.  So you'd be choosing words from there, not from the universal dictionary.

Activate 2fa so you are the one who can open your wallet here in crypto

Then to avoid hack or scam use trusted already like we have different wallets here without accusation

Another thing cryptocurrency create for saving money in our own place and without regulator like this is run for long like that

That doesn't make sense. Native wallets have no 2FA.

So there are 12 words chosen from thousands to recover any wallet.

If you iterate through random word combinations you will eventually generate a wallet that exists, correct?

I know the number of combinations is astronomical. But in theory if you keep generating random phrases, you might eventually stumble upon a wallet holding millions?



It is very much harder to generate 12 correlating words to get a random account
That’s why it’s safe and secure using such paper wallet

And the opportunity to stumble on an existing wallet is 1 in a billion

1 in a billion can be tested in a few seconds

So there are 12 words chosen from thousands to recover any wallet.

Yeah, the odds are crazy and almost impossible to break. Some of the comments here do have a point but as someone who's holding a lot of their savings in 1 wallet, you will always have these thinking that its still possible for someone to do it. Hardware wallets, I would say, are the best thing you can have to get the utmost security you want for your coins. Mine has 2-f authentication to complete before you make any transaction and can store collectibles, just for fun! It's not really that bad to invest around 90~100USD for a wallet that can help you have an ease of mind.

Hardware wallets use the same kind of keys as software wallets. If you stumble upon a key using software, then you don't need to access the hardware to get the funds out.

Theoretically, if there is a specific list of words from which the recovery phrase is formed, you can try to hack. But I think that the list is randomly updated with new words and therefore no chance.

That's right. I was looking at the source code for a popular crypto and it's fixed list.

No you cannot change the words otherwise you'd break the previous existing wallets. The word list is static.

You think you are clever, if it was truely possible and worth the time you must have to spend to find out the correct seed, a lot of people would do it before you. Bruteforce doesn't work that much of easy.

I don't think I'm clever, I'm asking a theoretical question.

I never thought about writing random seed words to the Bitcoin wallet but it is almost impossible to guess the right combination. In my opinion, you can use the most commonly used word list for having a stroke of better luck. Only luck can help if you want to find a BTC on random wallets.

Not Bitcoin, but others like Cardano. They use 12 words and the word list is fixed. I wonder how secure that is.

purely theoretically, any wallet can be hacked into the matter in that you need to know which wallet to break and you need to understand that it will take a lot of time.

That's what I think too but doing it randomly maybe you'll stumble upon a billionaire wallet.... I wonder if anyone is doing this out there?

OK thanks for all the replies.

So I realize the combinations are absurdly large.

Theoretical question here: isn't every 12 word combination a valid wallet using the valid words?

By simply concatenating the words randomly I can create a wallet. Right? Wrong?

Only way is if someone finds a brutal software flaw that would destroy it. Otherwise there will always be some demand and therefore some price even if very low.

Remember that any wallet that runs in the browser mus trust the javascript engine in it.

What this means is any program that accesses the JS engine can access your keys.

So spyware, other plugins and addons all can read your private keys when you use them in your browser.

I wouldn't use a browser for anything serious TBH

DOGE is only mined by Litecoin miners.

Nobody mines DOGE itself.

If anything happens, there are zero people mining DOGE so it's a big risk holding it IMO.

There's a reason why transactions are cheap: nobody uses it, nobody mines it.

Doge only survives because of LTC miners.
