1402  Bitcoin / Development & Technical Discussion / Re: Mining pools publishing lists of transactions on: December 17, 2013, 01:10:06 AM
they don't do that because:
  • it's going to cause extra server load from thousands of people refreshing every 30 seconds to see whether their 0.0001 BTC no fee transaction went through
  • it's extra work that does not benefit their customers (miners)
  • it doesn't generate revenue

1404  Bitcoin / Bitcoin Technical Support / Re: How to backup a wallet on: December 16, 2013, 04:51:56 AM
I have a wallet with 14 addresses inside, I want to back these up to another PC (ie Move them completely), Is this just as simple as copying the wallet folder (ie the .dat file), and loading it onto another PC?

I know the password so this should work without any errors, correct?

Yep, that's all there is to it. But don't forget to do it after every transaction. And also move it to a PC or device not connected to the net. A USB stick for example.
That is excessive. You only need to backup once per 100 sent transactions.
1405  Bitcoin / Bitcoin Technical Support / Re: What happens if you send some bitcoin to a non existing address? on: December 16, 2013, 04:48:21 AM
Ok, so what happens if you send some Bitcoins to an Altcoin address that is based on Bitcoin? Since the checksum test should be the same (I guess many altcoins don't change that part of the code), does the transaction end up in nirvana?
the network bits are different so it will also be rejected.
1406  Bitcoin / Bitcoin Technical Support / Re: What happens if you send some bitcoin to a non existing address? on: December 15, 2013, 11:26:03 PM
bitcoin addresses have a built in checksum. a typo will most likely* be rejected by the client and the funds won't be sent.

*1 in 4294967296 chance for typo to bypass check
1407  Bitcoin / Development & Technical Discussion / Re: Is it possible to start a new Bitcoin network? on: December 15, 2013, 10:59:06 PM
yes you can, but you need to change the bootstrap nodes and the block checkpoints.
1408  Bitcoin / Bitcoin Technical Support / Re: How to backup a wallet on: December 15, 2013, 10:48:29 PM
yes, but verify the backup just to be sure.
1409  Economy / Service Discussion / Re: 1 BTC stolen from BlockChain wallet -- assuming weak RNG on: December 13, 2013, 06:06:02 PM
My guess is that back when I used Blockchain.info in April, it had that RNG flaw that was discovered in August, and now that I was using the address again, someone used the key exposed in the prior transactions to grab the funds.
the RNG flaw was only on keys generated by android wallets.

A lot has changed since 2011.  Has anyone updated this instruction set for the more recent version of Bitcoin?

1413  Alternate cryptocurrencies / Mining (Altcoins) / Re: Anyone using PCI-e Multipliers? on: December 12, 2013, 12:42:29 AM
I have run across this listing, and I'm wondering if it will function properly mining with a lot of cards, using the BAMT linux disto, or any other linux setup.

Are there any limits to the number of GPUs per system? Will running 4 pci-e 1x cards per slot x 5-6 slots overload the pci-e lanes?

http://www.ebay.com/itm/PCI-e-express-1X-to-4port-1X-16X-multiplier-riser-card-cable-4-diy-bitcoin-miner-/321248295196?pt=LH_DefaultDomain_0&hash=item4acbe3f91c

I was sticking to 5 gpus per system, on the cheap base systems I have (gd45 mobos, 8gb ram) but the idea of turning that into 20-25 gpus per base unit would be very entertaining! (Not that I could find enough GPUs to fill it at this time)


for $80 you can get a whole new motherboard with 4+ slots.

I'm interested.
Do you provide lower shipping for recipients in Canada?

I will not use escrow. Your payment must be made directly to my wallet. (If I am risking sending you this coin, you must risk sending me the Bitcoin. We will be equally vulnerable.)
that's not very assuring coming from someone registered 5 days ago.
1415  Bitcoin / Bitcoin Technical Support / Re: Any issue with multiple wallets on the same drive? on: December 10, 2013, 10:05:51 PM
thanks, should I choose the "detach database" option also?
That option has no effect. As of version 0.8.0 and above, all the block files are no longer stored using BDB. Only wallet files uses BDB, but those are "detached" with every write by default.

horrible way of doing transactions. the buyer can scam by tracking the package and spend the funds once it arrives. the buyer can also scam by spending the funds, then claiming the buyer spent the funds.

Quote
The account holder had a randomly generated password which would have been difficult to Brute Force, so there is a very good possibility that the hacker has access to the database. With all due credit, CEX.IO does have 2 stage authentication which the user could not access as he did not have a smart phone to perform the security. So far, no comment fro CEX.IO
or his computer was keylogged, which is far more likely because there's no large number of hack incidents.

flip 256 coins, then use those bits (heads/tails) as private keys.
