601  Bitcoin / Press / Re: [2017-12-04] Is Bitcoin Diamond a Better Bitcoin? on: December 04, 2017, 03:12:12 PM
Bitcoin Diamond is yet another shitcoin fork of bitcoin.
It is worst than the rest as the supply was increased by 10 and it doesn't even have a blockchain yet!

Terrible decision that will end badly.
They can't take care of their own fiat currency that they can print at will.
How will they be able to take care of a deflationary public cryptocurrency?
603  Bitcoin / Development & Technical Discussion / Re: Need a new bitcoin with Turing complete smart contract on: December 04, 2017, 10:37:11 AM
Bitcoin already has Rootstock, a sidechain, to provide smart contracts.
And you can deploy Solidity/Ethereum smart contracts on the Rootstock chain:

605  Bitcoin / Development & Technical Discussion / Re: probability of cross privkey for holders on: December 02, 2017, 02:39:48 PM
In order to spend money sent to a Bitcoin address, you just need to find a ECDSA public key that hashes to the same 160-bit value. That will take, on average, 2^160 key generations.

Supposing you could generate a billion (2^30) per second, you need 2^130 seconds.

Doing this in parallel using a billion machines requires only 2^100 seconds.

Getting a billion of your richest friends to join you gets it down to only 2^70 seconds.

There are about 2^25 seconds per year, so you need 2^45 years.

The age of the Universe is about 2^34 years so far — better get cracking!

You need the wallet.dat file or else there is nothing you can do.

Wallet data is not stored in program files or dll.

0.001BTC was burned here: https://blockchain.info/address/1xPPxProfitProphetSyndicatev6F9Ce and I accidentally sent 0.88BCH to a BTC SegWit address. I'm just doing my part to make everyone richer, guys!😂
If you want to recover your BCH see this Reddit post:

610  Bitcoin / Press / Re: [2017-11-25]Bittrex Issue New Trading Policy on: November 26, 2017, 11:09:27 AM
The policy is a welcome one, especially the ban of pump groups accounts.
But how will they know which accounts belong to pump groups?
There are tools used to detect increase in volume of coins like Cryptgany so you can catch pumps.
What if they ban plenty of innocent accounts that use these tools?
611  Bitcoin / Development & Technical Discussion / Re: Upgrading to 0.15.1 over public WiFi on: November 26, 2017, 10:36:53 AM

It is absolutely safe if you use it right, as it was intended. Online wallets aren't really wallets, they are banks with a new name. You are trusting someone with your money, you trust in their honesty and their capability to keep them safe. And online wallets, just like banks, have a horrible track record on security. This is why Bitcoin exists in the first place, it is weird how people get into Bitcoin and completely miss the most simple basic point of it, "own your money".

Using a software wallet like Bitcoin Core, or even Electrum, is absolutely safe over public wifi, VPN or Tor. The money never leaves your PC, so it is always safe if your computer is safe. And if your PC is not safe, then not even God can help you, everything you ever got in touch with in cyberspace is gone.

Run your own wallet, your own software, your own OS. Don't trust someone else with your security, they neither care nor are capable of helping you.
You can't make a person safe if they insist on running in front of cars, they need to take security in their own hands.
There is no reason not to run Linux and software wallets. The stupid reasons people think exist are mostly spread by fearful and the ones who profit form it.
They are afraid of something small and normal like the smallest change that they can get use to in ten minutes, but are not afraid of actual real problems where they can lose everything in a second and are only safe for as long as their luck runs, which is never too long.
Thank you for your reply.
I understand now

I would rather say that someone just grabbed his cookies or credentials from thin air. It is a trivial task, I can do it in my sleep.
It sounds like indeed he was using an online wallet, which probably didn't have HSTS support.
To be honest tho if he used Windows, which the poor guy probably did, he could have been hacked by a basic script-kiddie as there are many vulnerabilities in SMB protocol these days, which just needs an attacker to be on your LAN.

That should be a warning to people now more then ever as there are no secure Wifi connections anymore due to the Krack attack.
Eventually router vendors will start selling updated routers which will eventually reach the common population, but just a year ago I could see a decent percentage of people still using WEP, so it might take few decades.
So it's not safe to use bitcoin and other crypto over public WiFi?
What about VPN?
Can VPN steal bitcoin too?
613  Bitcoin / Press / Re: [2017-11-20] Roger Ver Declares Bitcoin Cash to Be True Bitcoin on: November 24, 2017, 11:58:42 AM

I will use the coin which has more users and lower transaction fees.
That's bitcoin (BTC).
614  Bitcoin / Press / Re: [2017-11-20] Roger Ver Declares Bitcoin Cash to Be True Bitcoin on: November 23, 2017, 10:55:11 PM
Everyone be like "Nonono BCC is an Altcoin..." it's nothing more than Bitcoin itself with a slightly different codebase. So whenever Bitcoin changes ist codebase, it's automatically an altcoin? We will see what happens, BCC is the better product to use so to my mind has a good chance to overtake Bitcoin.
Are you trolling?
Or do you really believe that because BCash has almost the same code as BTC that it's bitcoin?
In that case, is bitcoin gold bitcoin?
What about bitcoin xt?
Or bitcoin unlimited?
Or bitcoin diamond?
Or any shitty forks that will occur?
615  Bitcoin / Press / Re: [2017-11-23] Boycott against wallets and exchanges without SegWit on: November 23, 2017, 01:11:39 PM
The boycott is not the way out. If there is a problem it should be solved through negotiations. Always a bad peace better than good war. You not only what was happening with bitcoin at the end of last and beginning of this month? Do you want to undermine the credibility of bitcoin and destroy it with their hands. Everyone has an opinion and it is always possible to reach consensus.
I agree.
Attempting to boycott will provide unwanted pressure and they can break things of it's not implemented properly.

617  Bitcoin / Development & Technical Discussion / Re: signing message from segwit adress on: November 13, 2017, 10:22:46 PM
Culled from Reddit:

"All of the signature validation software that I've seen expects a P2PKH address to resolve. Signing with a P2SH-P2WPKH address could be done by deriving the P2PKH address from the privkey, signing with the privkey, and including the P2PKH address along with the signed message. This probably isn't done due to UI.UX concerns whereby the signer might believe that a wrong privkey is being used. Other than that, it's certainly possible.

The situation is similar with sweeping addresses. We derive both P2PKH and P2SH-P2WPKH for sweeping now, so sweeping P2SH-P2WPKH addresses using the privkey is possible.

Something like this: https://pastebin.com/zZCmzsJr"
Segwit addresses are P2SH-P2WPKH and you can't sign messages against P2SH, for example you can't sign a message with a multisig wallet.




By the way, Samouri Wallet for Android has a new option to sign messages with Segwit transactions so it's definitely possible:

Anyone can correct me if I'm wrong.
618  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Transaction Stuck for 2 Days on: November 13, 2017, 06:03:50 AM
Bitcoin is more profitable to mine and hashpower has switched there so you can wait because the mempool will be cleared soon.

Or you can use a transaction accelerator like ViaBTC: https://pool.viabtc.com/tools/txaccelerator/

Hi

Is Segwit2X fork cancelled or it will happen

I can't find the real answer. So help me and move this topic on correct place.
It is "suspended"
https://lists.linuxfoundation.org/pipermail/bitcoin-segwit2x/2017-November/000685.html

It is most likely cancelled forever.
The proponents have moved to BCH or other altcoins (Garzik is working on his own altcoin Metronome)
