Re: What is the difference between Monero (XMR) and Bytecoin (BCN)?
by
scientific
on 17/01/2016, 14:38:55 UTC
Both will probably be non-existent in a few years. If by some chance Monero survives it will find its use as a privacy-centric currency / store of value, not as an investment vehicle. The non-fixed emission (to maintain mining incentives ad infinitum) means that it will never have the same scarcity as Bitcoin, but I think it's already been demonstrated that scarcity in altcoin distribution is wholly overrated.

Fluffy, what do you mean Monero will probably be non-existent in a few years? What makes you say that?

Re: How to export private keys from QT and import into blockchain.info ?

You can also use pywallet to dump all the private keys at once and paste the output into the blockchain.info wallet.

https://github.com/jackjack-jj/pywallet

You will need to have Python installed.

Re: NETELLER forwarding service
by
scientific
on 04/05/2015, 05:19:21 UTC
Well, I've recently found out myself this won't work. If someone deposited using bitcoin and sends you that money the same restrictions also apply to you, and there's no way for you to know beforehand except trusting the sender.

So you tried using the NET+ card and it didn't work?

Yeah that's what happens, you can try it yourself. I'm guessing they're now internally separating your account balance between "normal funds" and "bitcoin funds". The normal part you can spend as usual while the remaining is blocked.

Not yet - send me a message if you wanna try it.

Many of you (myself included) ordered a NET+ card and now we cannot use our bitcoins to fund it. I'm offering to fund my account with bitcoin and forward the money to your NETELLER which will hopefully make the funds available for your card transactions.

Fees

None, because:

* I cannot guarantee that this actually works
* despite being a member for years I don't have any trade feedback on bitcointalk (escrow is possible) - please leave feedback if you're satisfied

Limitations

* only round sums like 10 EUR, 20 EUR, 30 EUR, ....
* only possible when I'm online (Skype: chmod755.) and my limits are not reached

Have you been able to try this with anyone? Does it work?

Re: Bitcoin-QT bypassing Tor
by
scientific
on 20/04/2015, 13:50:22 UTC
I'm running Bitcoin Core 0.10.0 and while I have it configured to run through Tor only its been a few weeks that the client tries to bypass Tor and connect directly to 100.64.68.8 or other IP addresses in the same subnet.

My reverse firewall is blocking it, but it seems very strange to me that the client tries to bypass Tor, that looks like a privacy/security problem.

Anyone has seen the same behavior?

Can you reproduce this every time? I mean, does it happen right when you start the program or at random times?

Today it happened right when I started Bitcoin Core, but usually it happens at random times.

Certainly shouldn't happen. Are these connection attempts to remote port 8333 or something else? Maybe you can get a packet capture.

Re: Recover the password for the bitcoin wallet by using an unencrypted backup
by
scientific
on 20/04/2015, 13:46:48 UTC
I’ve lost my password for bitcoin wallet Smiley

But I have unencrypted backup of the wallet that was made a year ago.
Unfortunately, bitcoins stored on addresses that contained only in ciphered wallet, not in unencrypted backup.
But some addresses are contained both in the encrypted and unencrypted wallet backup

I have idea:
- choose any address that contained in both the ciphered wallet and unencrypted backup
- extract private key for address from unencrypted backup
- extract ciphered private key from ciphered wallet
- compare two extracted strings and get password for the wallet

I have superficial knowledge of cryptography, but this should work Smiley

my idea is feasible?
Anyone know about software that can do what I described?
Can anyone create such software for reward?

You can't do this anyway. Bitcoin Core uses AES. Read here: https://en.wikipedia.org/wiki/Known-plaintext_attack

Re: Dash versus Ring Signiture Coins
by
scientific
on 20/04/2015, 12:37:28 UTC
Since Dash supporters have recently started a campaign that Ring Signature coins can't be audited due to their private nature, I've decided to start a thread to hash it out publicly.

I thought that's the whole point of having an anonymous coin. Besides, if you need other people to see your funds you can always give out your viewkey, problem solved.

Re: Bitcoin-CLI Issue - Error Parsing JSON:sendtoaddress
by
scientific
on 06/02/2015, 15:36:53 UTC
Hey,This may very well be a stupid question - but I am trying to send some BTC using the command line interface (Windows 7) using the following commands:

bitcoin-cli walletpassphrase xxxxxxxx sendtoaddress "13Eu3B2VG8irHcwX3b2Emk1LaDVMDDamJB" 0.01 "test" "2nd wallet"
or
bitcoin-cli walletpassphrase xxxxxxxx sendtoaddress 13Eu3B2VG8irHcwX3b2Emk1LaDVMDDamJB 0.01 "test" "2nd wallet"

But no matter which variation I try of above, I receive the following error:

error: Error Parsing JSON:sendtoaddress

I've also tried the same with bitcoind and had the same results. Does anyone have any suggestions? I'll admit I am pretty new to command line anything, but alot of googling and searching has not revealed an answer. Any assistance is greatly appreciated!

Because that's not the correct syntax. Use these:

Code:
bitcoin-cli walletpassphrase
bitcoin-cli sendtoaddress [comment] [comment-to]

Most VPS's are overcrowded with other customers anyway, so it'll have poor performance. You may have a fast connection, but must of the time is spent in verifying the blocks (CPU and HDD time), therefore it's normal.

Why not just verify it? Not that it'll be easier for you to buy BTC with it, but just asking.

Re: Why Do Cryptocurrency Exchanges Want So Much Information?
by
scientific
on 03/01/2015, 13:47:36 UTC
I've been mining a few coins for a while, including BTC, but I'm ready to actually buy some altcoins on an exchange, 'cause the price is right. I'm looking at Cryptsy, and to be honest, I'm a little reluctant to give my personal information to the site. It all seems legit, and I know many have done it before, but what is the purpose of needing things like photo ID and whatnot? Is that a US thing, or does pretty much every exchange want that information? And if they do... Why?

I believe for higher verification, some even want a Social Security Number? Why is that? Does anyone have more information regarding why they would collect that information? I don't necessarily doubt the honesty of Crypsy or any other big exchanges. But at the same time, I'm not going to run and give them information that they shouldn't have.

Thanks for any information you guys can give me. Smiley

Many exchanges don't need any of those information for buying/selling altcoins, so you should be fine. Those requirements are mainly for fiat transactions.

Re: Have different ways of payment : what's best ?
by
scientific
on 03/01/2015, 13:41:15 UTC
Hello,
I'm willing to buy Bitcoins for an approximate value of 140$.
I was wondering what is the easiest, simplest way to do so.
I have a verified PayPal although I'd prefer to pay through ukash voucher which I could convert to a Ukash MasterCard working with any service allowing MasterCard.
I'm not willing to give too much personal information whatsoever and am honestly tired of putting them on the many web sites I tried.
Thanks a lot!
Nz0s

Try the exchange section for that: https://bitcointalk.org/index.php?board=53.0 . You'd have hard time buying with PayPal though anyway, ukash would be easier.
