5441  Bitcoin / Development & Technical Discussion / Re: Bitcoin ATM Malware Found For Sale In The Dark Web! on: August 17, 2018, 03:55:30 AM
I wouldn't call that "news".
Even regular ATMs got a bunch of "for sale" malwares and hacks available on the dark web, but most of them are fakes.
Are there any ATM hacking incidents lately in the news? Yes?

I'd say, this is just news-makers are just doing their jobs. Exaggerating little things.

Why do we need an Off-topic section at the first place?
Off-topic is a good place to dump threads with constructive but not crypto-related topics, archival isn't the place for them IMO.

@hilariousetc I second the latter as I mentioned in my previous reply.
Implementing it on Politics Board as well will increase the efficiency of reports/moderation once (it)they start on posting on heavily-moderated boards.

...
We need a mod for off-topic. That should be considered majorly right now.

Poor guy who will get this job...
Being a mod in the off-topic section... kinda mission impossible...
-snip-
Moderating an out-of-forum discussion board can be nonsensical, and yes it's a hell of a work for moderator(s).
Why don't we just disable Post count from off-topic board (just like posts from Serious Discussion) and possibly, on other bot-infested boards to discourage those lazytards.

Just learn how to efficiently use the search function
or ask for Jet Cash's Ignore List and apply it to your own profile Tongue That could minimize the spam.

5446  Bitcoin / Electrum / Re: Strange TX "+0." and can't sync on: August 06, 2018, 06:27:38 AM
How can get private keys without sync?
You can always get the private key of an address using the right-click menu from the address tab.

First, update the old version electrum to check if it's really funded or check the addresses' balance from any blockexplorer.
Do Abdussamad's suggestion to update your Electrum.

5448  Bitcoin / Electrum / Re: My bitcoins disappeared after reopening Electrum (3.0.6) on: July 27, 2018, 03:13:23 AM
I can not use the seed option, no password wallet and that option disabled, it's watching only wallet.

 Huh Huh Huh
Wait, what? It's a watch-only wallet?
then, you've possibly made it using (imported) bitcoin addresses and not private keys.
The most possible reason why your bitcoins suddenly disappeared is the person who owns the private keys of those address must have sent them to another wallet.

The third one, shows all transaction history, but no bitcoins.
Can you tell us the Transaction IDs of the third wallet? And tell us which addresses belong to you and the ones that you're not familiar.

This is just to confirm my suspicion (you're a victim of a scam), not a way to recover your funds.
5449  Bitcoin / Electrum / Re: Cold storage signing - Error: Server did not answer on: July 26, 2018, 10:25:36 AM
Edit, I am using multisig when I received the error.
I created a test single signature wallet, and offline signing worked just fine....hmmm.
Any advice how to do multisig in an offline, cold storage environment?
Ok, a couple of pointers for you in order to know why is it impossible to make cold storage Multisig electrum wallet.

First, a transactions from a multisig wallet requires signatures from three different private keys, from your wallet and (two?) from "Trusted Coin" services which provides the 2FA security.
It will require your client to connect to the server in order for TrustedCoin to sign the transaction.

Second, when you created the Watch only wallet using your cold-storage's xpub key (master prublic key), it only created a new wallet based on one of the private keys of your wallet, thus, the addresses would be in the legacy format. (confirm this by showing the address tab)

Lastly, if the watch-only wallet is funded and you want to spend it, you can make an Air-Gap Cold Storage or a spendable Electrum wallet using the paired xprv key (master private key) of the xpub key that you have used to make the watch-only wallet.
5450  Bitcoin / Bitcoin Technical Support / Re: Does a Bitcoin full node need to process transactions after downloading them? on: July 26, 2018, 04:52:36 AM
Could be the data directory, but it's already at height=330623.

You mentioned that you've used a Windows Computer to "download" the blockchain, did you downloaded it from torrent/hosting service or copied from a full synced node?
Because the chance that the source (is outdated) wasn't updated to the latest height is high.
5451  Other / Meta / Re: BCT have gone a little QUIET. on: July 25, 2018, 08:57:05 AM
I have an idea: Lift AntiCen's or his alts' Ban, then the Bitcoin Development and Technical Discussion board will be busy and lively as always. /s
It seems like users are now more active on reporting posts and moderators are now much more active in my observation (their response time to my reports).
And theymos might be planning to add a little incentive to active reporters.
Heroes and Legendaries are paying for a useless title "copper member" to pimp their profiles so, a badge will surely encourage most users to use that button.
Many reasons :

1) Bitcoin related searches and queries have went down. Most important reason.

2) Merit system also helped discourage spammers.
Thanks! If I didn't saw this post I wouldn't have noticed it.
5452  Bitcoin / Project Development / Re: Which field can blockchain technology be applied? on: July 25, 2018, 05:34:55 AM
The previously discussed new "Automated Election" system.
For example, every party can run their own nodes which can individually validate the election result, POW should be fairly distributed among all the "watchers" and concerned parties.
Interestingly, Ethereum Tokens can be used on Online Games' item ownership.
A player character can be issued with an ETH address and several rare items are tied to a token with a limited number.
However, trading them will require a transaction so it might take some time.
And it (Permissioned Blockchain) could serve as a distributed data storage of any small-sized documents.
5453  Bitcoin / Hardware wallets / Re: John Mcafee & Bitfi launch the first 'unhackable' hardware wallet on: July 25, 2018, 03:22:49 AM
wow this is interesting, Im going to keep an eye on this. I only have a ledger right now but am very interested in this "unhackable" wallet.
Did you even read the previous posts? Delete it from your "to buy" list.
It's basically a brainwallet which has a horrible history in terms of security and compared to ledger, Mcafee's endorsed "unhackable" wallet is a joke.
Not sure if you are trolling, but the address that links to "god" had about $100 of Bitcoin transferred through it less than 12 hours ago.  Cheesy
I've seen that too.
Actually, I have an Electrum Wallet named "Collision Tester" which contained the private keys of the most common brainwallet passphrases like Satoshi, free bitcoins, free bitcoin, etc.
But unluckily, I never got the chance to transfer the funds since it's impossible to monitor the wallet 24/7 manually.
5454  Alternate cryptocurrencies / Mining (Altcoins) / Re: Mine with old desktop? on: July 24, 2018, 09:15:46 AM
-snip-
Hey, thanks for your reply. Jut one quick question. Actually two. What do you mean when you say quality should be my main priority (something like that the power supply is stable?)? Can you refer good and reliable power supply brand? Maybe from your own experience. Thanks 🙏
Stability? maybe yes, but it's quite hard to tell unless you can get a free sample to test.
But the brand is the best criteria on how to find a good powersupply.

Personally, my not-for-mining rig which has a single comparable GPU and mostly operating 24/7 uses 450W Evga PSU.
Based on your build, this should be sufficient and cheap as well: EVGA 450 B1 except if you're not planning to upgrade in the future.
For a tight budget, that's a good pick.

But do not expect any profit from a single GPU rig, you can start mining JFF & experience.
You can use the rig for something else anyways.
5455  Bitcoin / Development & Technical Discussion / Re: Change Mobile Phones with Wallets on: July 24, 2018, 07:54:56 AM
would it be better for me to just transfer all coins to my account on an exchange or a desktop wallet, and that way all funds are off my phone?
Yes, that's fine, but do not send it to any exchange except if you're planning to buy another digital currency.
The current recommended transaction fee (based on Electrum's recommendation via mempool) is 10sat/b.
Sending them to another wallet/address isn't going to be expensive unless you have 100+ inputs.
5456  Alternate cryptocurrencies / Mining (Altcoins) / Re: Win update .... on: July 24, 2018, 07:35:27 AM
I did not turn off the update, I only changed the reg file to drag it allegedly from another server, which does not have an update. After that, I did not have a problem with the update  Cool Cool Cool
Chill, he's talking about m1n1ngP4d4w4n's post regarding GPO (Group Policy Object) which is a feature of Windows (Pro and above).

Why is it "that" hard for others to disable Windows update?
By disabling "Windows Update" in the "Services" then immediately restart the system (using the restart/shutdown button on the start menu, not hardware button), updates should be disabled.
Unless if there's an already downloaded and applied update which will complete itself during the restart process which could turn WinUpdates to "automatic" again.

Super.
And are copyrights free?
That doesn't even related to blockchain technology, it should be more of a storage (boxes) or pages of a book.
Why locks?

Google must have misinterpreted blockchain from lock. Take a look at this: BLOCKCHAIN
And the image depicts a "chain of locks" which can also be called "lockchain".
See what I mean?
5458  Bitcoin / Electrum / Re: Delete wallet on Android on: July 24, 2018, 05:45:46 AM
For reference in case if someone wants to backup/transfer the wallet files manually,
the wallet files were stored inside the android phone's internal system data folder, not in the internal storage (root access is required)

Found this by using google search:
I just downloaded the electrum wallet on android. And since my smartphone is rooted then I tried to google also but never see an answer on it. So I tried to navigate it on my own and found it on
/data/data/org.electrum.electrum/files/data/wallets then there's "default_wallet" file there. So you need to have a jailbreak/rooted phone to navigate it.
5459  Economy / Speculation / Re: Bitcoin fair value is above $10,000 on: July 23, 2018, 11:03:15 AM
I'm so weak, fell for it and I've clicked the the link.

Anyways, the article focuses more on charts and the rumor about CoinBase's hidden actions. (no spoilers)
I've seen a lot of related rumors around here in the speculations board and there aren't much of a difference except of the enthralling format.

Probably this was just posted here to gain more traffic, but who am I to judge, there's nothing wrong with it.
5460  Bitcoin / Development & Technical Discussion / Re: In order to improve mining and the max transaction rate of the network... on: July 23, 2018, 09:02:13 AM
Welp, shared ideas from a random member could be a gold mine.
Even the simplest simple-thoughts can be as great as well-processes ideas.

But frankly, most of these (OP) has already been discussed thoroughly.

2. Minimize the block time by keeping the mining difficulty as low as possible without jeopardizing network stability and consensus. This will also help decentralize mining.
This will also destroy the fixed supply property
but maybe, the Author wants to tell us that all of those four (list) to work together to patch the negative effects of implementing just one.
Combine #2 and #3 and there's a possible work around to increase the block time without destroying the fixed supply.
Combining all of them will pose a threat to the seemingly perfect decentralized setup we currently have.

Overall, it's a bad idea.
