Its known that this is not real virus, it's just some prankster put signatures to the bitcoin blockchain, so now it reports as virus on every Bitcoin pc

82  Bitcoin / Development & Technical Discussion / Re: Core or Classic? on: March 29, 2016, 02:59:55 PM
Classic is only popular in the u.s, while Core is mainly used in the rest of the world.

Therefore, if you are living in us you can use classic, if you live outside you can choose Core.

In the traditional system like Banks, the problems like hacks are swept under the rug.

Common person will never learn that his funds were hacked, because Bank simply prints more money and pretends nothing happened.

For this reason police never solves these crimes, because nobody ever reports them. The people are deceived that nothing had happened.

This makes the police and other actors to think that standard organisations like Banks are very secure because hacks "never happen".

Of course both law enforcement and people are deceived in this way for decades now.
84  Bitcoin / Development & Technical Discussion / Re: is it possible to send zero bitcoins on: March 28, 2016, 11:49:13 AM
Yes it is possible. A transaction sending exactly 0BTC (recieving 25BTC and fees) is called also a coinbase transaction. The coinbase transaction is part of every mined block. The miner receives the funds. This transaction is used to claim the mining reward, and is similiar to creating funds from thin air (writing a number to account number on a Bank computer) or printing money in a traditional system.

Only miners have the ability to do this.
85  Bitcoin / Development & Technical Discussion / Re: Sybil attack to prevent blocksize increase (hardfork) on: March 28, 2016, 11:13:46 AM
yes sibyl attack is very dangerous and it is often done by malicious actors such as governments and/or government controlled corporations. typically to corrupt or manipulate a voting or elections in the system.

Bitcoin has certain counter-measures again this type of attack built in. For example, users losing funds due to sybil attack is highly improbable(impossible).

89  Bitcoin / Bitcoin Discussion / Re: /btc is full of hypocrites or shills on: March 25, 2016, 04:27:30 PM
I think it's the same kind of shills the rich boys hire to shill for sanders from their mom's funds.

yes, whe know abbout it

no, we don't give a fuck

call me when bitcoin is actually attacked. oh wait the laws aren't in place

see you in two years guise
90  Bitcoin / Bitcoin Discussion / Re: /btc is full of hypocrites or shills on: March 25, 2016, 11:39:18 AM
well the shills enjoy scaring people but from what i see, they're not really harmful , worst they can do is give u minus points when you talk to them. but only thing they do is scary, lie, try to convince everybody, etc..

I feel pretty relaxed. Yes it can be shady , but the big business may be happening on the background.

the way they convince u is always the same. when u know the tricks u have no problem.
91  Bitcoin / Bitcoin Discussion / Re: /btc is full of hypocrites or shills on: March 25, 2016, 11:23:52 AM
The poet shills are there for kinda long time. They shill for their agenda.

but i don't think that there's 100% connection between the shills and the so called sillicon valley or entepeneurs and between the washington / wall street whatever people. they may be as well separate groups.

but then again im not a detective

anyway it's fully USA-related thing.

92  Bitcoin / Development & Technical Discussion / Re: Segwit details? N + 2*numtxids + numvins > N, segwit uses more space than 2MB HF on: March 24, 2016, 07:50:19 PM
Let's talk address format. If I remember correctly, segwit will use P2WPKH (20 bytes)   and P2WSH (32 byte).

The reasoning is because the pay to script variant needs to defend against a certain security bug, that would limit only 80 bits of security.

But , can we improve the alphabet itself. I mean, to move from base58 to base56? Removing some two letters. Perhaps wide ones like Wwm

Or even completely drop lowercase. This would provide 32 symbols:

 {ABCDEFGHJKLMNPQRSTUVXYZ123456789}

* 32 is nice round number
* O 0, I is removed cause ambiguity
* W is removed because too wide for very narrow low-resolution fonts.

Opinions?HuhHuhHuh?

Hey,
I was just wondering, is it possible for someone to hack an encrypted wallet.dat
Thanks

Encrypted wallet.dat are pointless because of keyloggers. If you afraid of hacking your PC, then you should not hold wallet on the pc but on different device, like computer without internet.

If you are afraid of somebody come to your home and steal your wallet and pc, this is much worse.

Are you trying to make a QR code that we can scan and also read? If yes, can we call it a QR text code? Grin

Yes you can call it QR text code Cheesy
I'm pretty close to having the scanner working. See original picture from phone camera:



After decoding:



It's not the best possible accuracy, but the basic thing seems to work.
A major challenge would be to add it to some kind of an Android app.

96  Bitcoin / Project Development / Re: AT and CLTV - Truly disruptive technology! on: March 23, 2016, 06:37:09 PM
This sounds really good. A p2p exchange with a massive liquidity could truly disrupt the ecosystem.
97  Bitcoin / Project Development / Re: Dapp Marketplace on: March 23, 2016, 06:28:53 PM
Sure let's create it. Did you begin? The site can be open source, is that a problem?

98  Bitcoin / Bitcoin Technical Support / Re: Why does the core wallet suck so bad? Dead people move faster than the d/l on: March 23, 2016, 06:16:38 PM
With segwit fraud proofs, spv wallets could provide similiar security to fully validating node

utxo checkpointing could further improve the status quo

100  Bitcoin / Development & Technical Discussion / Re: Backing up the blockchain to improve security on: March 23, 2016, 01:41:29 PM
This already happens.

In fact thousands of people's computers all over the world download the chain every 10 minutes and automatically verify what you've said.
So suspicious activity like reorganizations are spotted instantly.

What you read is the 51% attack. There used to be doublespends attacks back in the good old days of huge pools, against a dice roll gambling site. You can look it up, the site has a bug , that enabled the attack.

But currently there is no evidence that there's doublespends going on today, (except against 0-confirmation sites) so feel free to report or mention any suspicion that you may have.

0-conf sites don't really count as an attacks because everyone knows that accepting 0-conf transactions is unsafe.

EDIT: you see the problem with 51% isn't that it won't be spotted (it will), but what can be done about it.
Making Bitcoin centralized would "solve" the problem users have:
  • payments do not confirm
  • The attacker makes received funds return back to senders for fun
  • coins value drops to $0.01 ... actually the price will start tanking much sooner when rumors that 51% attack is about to happen
But miners can't mine anymore. Logical solution is to "upgrade" hash algorithm to Keccak. This would mean that attacker's mining devices become worthless instantly. But so will honest miner's devices. The huge problem is Bitcoin rules need to be changed, and the difficulty will drop. There is no consensus how to solve this issue, but it definitely can be done once Bitcoin is really 51% attacked.

Because then they could falsely sign transactions and double-spend without getting caught.

This is false. Even with 51% attack (or 99% attack or 100% attack) The real owner still controls their funds. But the attacker can return the funds back in time to previous owners or create fake histories. But the attacker cannot steal for example coinbase transactions, so users in principe could "put" their funds to miner's wallet to save the funds from going back to whoever sent them.


Another possible solution

The honest users can all go to factories and make more mining devices. In this way, the honest users could regain control of the network and "save" Bitcoin.

But don't worry. Dogecoin will work correctly.
