Good posting, a couple of points.

1. Live CDs. Your able to store things on Live CDs because they create a virtual file system file on the local drive. and merge that local file system with the filesystem that's on the CD.

what do u mean by "store"?  by being in a virtual state isn't the virtual file system just temporary until u logoff live cd unless u decide to save the wallet?

Quote from: je_bailey
If you install your wallet on the Live CD. You are actually putting in on the hard drive of your computer. ( see http://en.wikipedia.org/wiki/Live_CD#Technique)

which then means it can be stolen despite not being logged on with live cd?

Quote from: je_bailey

2. I object to the usage of "100%" secure. There's no such thing Smiley The closest you can come is to make it portable at which point you're vulnerable to physical theft and loss.

In breaking news 2.6 million pounds has been stolen from a train in the UK. Please STOP using fiat currency immediately!

why?  there's unlimited amounts of it Wink

I read the wiki page https://en.bitcoin.it/wiki/Transactions but it's still not quite clear to me on why there's a change address or value.

Quoting the wiki: "If the input is worth 50 BTC but you only want to send 25 BTC, Bitcoin will create two outputs worth 25 BTC: one to the destination, and one back to you (known as "change", though you send it to yourself). Any input bitcoins not redeemed in an output is considered a transaction fee; whoever generates the block will get it."

0) Why does that happen (the change itself) if I'm sending the exact amount I want to send?
1) As I understand, the change address is created and saved in the wallet.dat file but doesn't show up in the User Interface (UI). So how do I claim my money?

0) because even if you want to send exactly 20 btc, your wallet may contain addresses which have the following balances:

10 btc
15 btc
19 btc
25 btc

So what does it choose? It might choose something like the 10 and the 15, combine them together to send 25, sending 20 to your destination, and 5 back to a change address.

Then you'd have the following in your wallet:

19 btc
25 btc
5 btc (residing in the new 'change' address)

1) it's automatically claimed and will show up in your balance.

you're on the right track Alex, but the client will search for larger amt addresses than the tx itself, ie, it won't combine 2 addresses of lesser amts.

Ah okay, so from my example, let's just say they didn't have a 25 btc address in their wallet, then it would have to combine two smaller ones.


Alex, i must apologize.  i spoke with Theymos about this issue and heres his response:

"It might choose a combination of smaller amounts. It doesn't always choose a larger amount.
Usually it will choose the closest match. The coin selection algorithm tries to reduce the amount of change, though the algorithm isn't perfect."

my bad...

A question:

If I open my bitcoin client, cycle through 100 addresses, copy the 101st, then send some BTC to that one, THEN encrypt and backup my wallet.dat file, are the coins I had in there before cycling through the addresses safe or only the new ones?

Thanks.

no, you're safe.  you can have thousands of addresses stored in your wallet, not just 100.
18805  Other / Beginners & Help / Re: HOWTO: create a 100% secure wallet on: June 16, 2011, 11:22:40 AM
Can't the wallet.dat be encrypted already? (password when starting the bitcoin client...)

As has been said elsewhere, this wouldn't work, since the client has to somehow decrypt the file in order to use it. Decryption => a decrypted copy is stored in RAM => a clever program can find and copy it.

So this would be rather dangerous, since it would give users a false sense of security, prompting them to be even more careless. I know lots of users are whining right now and blaming the devs for not including encryption, but this is simply the truth of the matter.

when u boot from a live cd, how is it that you can install a copy of Bitcoin with a new wallet that doesn't touch RAM?  if it does, isn't that an opportunity for a trojan to detect your wallet?

yes, thats correct, it would have to.

If you have any BTC beyond 10 on that machine do yourself a big favor and move them to a secure wallet running on Mac OS X or Linux right NOW!



given what happened to you, if you were just starting mining, would you join a big pool or stay independent?

Next, he deleted the wallet, because he thought it had already been backed up, when in actual fact only the first address had been.

Oh snap. Good to know though, and yes, the wallet only contains the addresses already generated at the time the file was backed up. I will refrain from mentioning this in the guide though, since 1: I advise against using the wallet you just backed up, 2: with the 10 fresh addresses generated, this shouldn't happen anymore, 3: I'm trying to keep it simple and hope not to confuse anybody. As Confucius says: Confusion is the death of non-confusion (and oversight)

wait an minute.  are u saying a new client install immediately creates 10 addresses?

which client version created only 1?

open a command prompt window and navigate to the directory where the executable is stored. Then type sierrachartfeed-0.2.exe -w

this doesn't seem to be working in win7.
18817  Bitcoin / Bitcoin Discussion / Re: t-shirt idea: "I am Satoshi Nakamoto" on: June 13, 2011, 06:11:54 PM
All shirts are now up! anymore u guys want up?

i'll buy the one i recommended designing above.  the I Am Satoshi Nakamoto is too wordy and crowded for me.
18819  Bitcoin / Bitcoin Discussion / Re: t-shirt idea: "I am Satoshi Nakamoto" on: June 13, 2011, 05:23:45 PM
Lol you're killing me smalls. If you just horde them, and I just horde them, who's gonna get them?

You're just passing the buck (lol), not the bit.

Satoshi you are not :-) You need a t-shirt that sez "I'm just riding this thing for money. Give me your most valuable currency (btc/usd/yen/spacemoney) now."

at least i'm spending money, be it USD or BTC, to support the Bitcoin economy Smiley
lol it would be cool to use bitcoin to but the shirt I will look into it Smiley

aren't u the owner of the site i ordered from?
18820  Bitcoin / Bitcoin Discussion / Re: >432109 BTC sent to 1 address, block 130281 on: June 13, 2011, 05:15:59 PM
For a privacy oriented crytocurrency it sure is really fucking easy to riffle through other peoples bank records. This needs something done about it, I don't leave my bank statements lying around on the sidewalk for any degenerate gutter trash to read, so why should it be the same for bitcoin?

dude, you were one of the doom and gloomers 2 days ago helping to precipitate a crash and now u complain?
