So this is one of these 'its a feature not a bug' type of things? I hate it when you can't see what's happening under the hood, also addresses are useful for keeping track of what my one mining pool sent me, what my other pool sent me... They're like folders and multibit is forcing you to adopt their 'wallets only for organization' paradigm. I remember clearly that once upon a time you could see the individual address balance in MultiBit, but rolling back to an older version probably isn't smart for safety reasons.
Quote
The addresses that you have given to people you can label to see when you've been paid by them.
Yes, you can label the wallet. Which means that if 20 people pay me rent every month, I have to have at least 20 wallets.
You can review incoming transactions to see who paid you what, and to what address.

There is no concept of per-address balance that is reasonable to present to users.

I receive a 1 BTC payment to an address I gave you, that address's balance is 1 BTC. I send a 0.01 payment to someone else, that address's balance is now 0. It should remain 0 and should not be reused.

Wait, what? Maybe http://we.lovebitco.in/how-bitcoin-works/transactions/ will give you some insight into the inner workings.

There is a concept of "accounts" in Bitcoin code that may be used by programmers, but it is not exposed or used by the wallet interface.

I've had the streaming interface running for about 8 hours, and it was showing trades as I started reading this thread. Just now it had just gone for ~320 seconds without receiving any trades, but just got prices again.

(Using this related script: https://bitcointalk.org/index.php?topic=339066.msg3636549#msg3636549)

Maybe nobody's trading today?

I checked http://data.mtgox.com/api/2/BTCUSD/money/ticker_fast, and it is occasionally updating, and matches the current stream price.

edit: just got a 502 gateway error from market json, site is not feeling well...
783  Other / Beginners & Help / Re: increase fee after sending? on: November 20, 2013, 07:22:15 PM
I've sent some BTC with a low fee..
0.0000001 is not a low fee, it is an invalid fee that will cause your transaction to be immediately discarded by any nodes or miners receiving it. You will need to remove the record of this transaction being sent from your own wallet to restore the balance shown to you, and then switch to a wallet that doesn't let you do silly things.
Hm, what's the criteria for validity?
A transaction requires a minimum fee of 0.0001 BTC per KB if the priority of the transaction is below 57M.
The priority calculation is based on coin amount you are sending and the time they've been in your wallet.
The baseline is 1 BTC requires 1 day before sending without fee is valid.
The smaller the amount, the longer the time, I investigated your coins a bit and it looked like they were just received.

Wait, I've type all this before, maybe I'll just answer with previous posts
:
A transaction sending 0.4 BTC with 100 confirmations is not high enough priority to send with no fee.

priority = sum(input_value_in_base_units * input_age)/size_in_bytes

((0.4 * 100,000,000) * 100) / 258 = 15,503,875

Transactions need to have a priority above 57,600,000 to avoid the enforced limit. I would recommend ANY payment include a fee even if it would qualify to be free, as "free transaction" space in blocks is limited, and profit-motivated miners have no incentive to include free transactions over those with fees.


It doesn't look discarded as blockchain.info sees it.
:
The blockchain.info client captures transaction info even when other Bitcoin clients might ignore it. If you create a junk transaction that nobody will relay, they'll still show it if it gets to them and put a 'double spend' alert even on the one that is valid.

It's discarded now.


Anyway, how do I remove the record of this transaction from wallet?
The wallet I'm using is bitcoind.

https://bitcointalk.org/index.php?topic=232979.0

Fees are required in most cases, it is part of the design of Bitcoin to compensate miners for the work they do making it cryptographically difficult to attack the blockchain. If you sent without fees, then you would have used an altered client that doesn't comply with the fee rules, and you get to eat your humble pie.
The optional fee in Bitcoin-Qt should be set to 0.0001 per/KB instead of 0, so all transactions have the minimum fee, if you don't want miners pushing back free ones for more profitable transactions.

You should not have to worry about your addresses in a wallet. The addresses that you have given to people you can label to see when you've been paid by them.

When you send a payment your wallet will compose your transactions from the best choice of previous payments you have received, which could be from the same or different addresses. When you send money, an amount is also sent back to another new wallet address. You only need to know that funds are available, not that they are stored in 20 different payments with 10 different addresses.

786  Other / Beginners & Help / Re: There is no faucet on: November 20, 2013, 12:50:07 PM
Faucets have more or less been killed off since they essentially send what is called dust (very small bitcoin amounts measured in Satoshis).  This clogs up the network so it is filtered out by most nodes.  As it currently stands the amount paid by Bunny run would be less than the fee to send it (kind of like mailing somebody a 12 cent check with a 50 cents of postage).

More like "I'll mail you a free penny if you send me a self-address stamped envelope".

A faucet originally gave out free bitcoins for testing and introduction when Bitcoin was new, bitcoins had no established value and some were willing to share easily-mined coins to introduce new users.

Now the word has been stolen by scammers enticing people to look at ads and click on links, or even nonsense like "1 btc raffle faucet". When these guys do pay, they pay dust that is cheaper to discard than pay the additional fees to get it out of your wallet. There is no faucet, click "ignore".

If you want to test Bitcoin with free fake money, start it with the -testnet option, where there is still a faucet and the coins are useful because they are worthless.

The data you need to recover is the private key. If the wallet has been encrypted, you are even more out of luck.

Here's a thread that has some information to identify what hex is around private keys:

No senator, there is no encryption or prime number-based cryptology used by Bitcoin to store or transfer value. However, please respond to this freedom of information act request, requesting transcripts of any testimony or council you may have received that may have informed you that the words "prime number" "encryption" and "trap door" go together...
790  Bitcoin / Bitcoin Technical Support / Re: How to "test" a private key? on: November 20, 2013, 09:34:01 AM
What you should be doing is testing the methodology used to create multiple keys, not testing a particular key.

Spending money sent to an offline address removes the associated security:
  • The private key must be put on an online computer system in order to spend the money, where it may be compromised, and,
  • Spending from an address reveals it's public key, which may reduce cryptography robustness.

Generate multiple paper wallets at the same time using the same method. Spend a test amount of bitcoins sent to one wallet (and discard it), ensuring that your creation and spending method is not flawed.

You will need to have some good information about what the password might have been. Think about all possible things you could have been thinking. Picture where you were when you were typing it in, what else might have made you think of a password. Were you able to decrypt it before (not a typo, truly forgotten). Write down all or any parts.

Then you need to create a word list, using phrases you might have used in different combinations, prefixes and suffixes. Combine them using brute force dictionary generation tools (can be found online).

A good password is not easily cracked. What people commonly type in and reuse can be.

She at least did mention Ripple with sparkles in her eyes during the hearing.
If so, we need to get the transcription, her credentials and association, and sticky the post "why Ripple is bad for Bitcoin and Bitcoin users".
794  Bitcoin / Bitcoin Technical Support / Re: confused about offline paper wallet on: November 19, 2013, 10:55:15 PM
A proper paper wallet is an address that only exists on paper. It is a savings account that cannot be hacked because it is not stored on a computer anywhere. I don't know what blockchain.info is calling a "paper wallet". Are you using their "my wallet" service, or just looking at addresses using the blockchain explorer part of their site?

bitaddress.org will generate one for you, using only javascript in your browser (no information is sent elsewhere). It is not part of a wallet or any online service, the private key information you calculate and print out is the only record that can spend money sent to that address, and only when it is put back into a computer. Lose the paper, lose any bitcoins sent to the address.
795  Bitcoin / Bitcoin Technical Support / Re: Transactions wait longer BUT Pools generate small blocks on: November 19, 2013, 10:47:09 PM
To fix the issue, pay more fees.

Is it extortion? There were a lot of 100K blocks, plenty of room for my transaction. I hope pool owners won't cooperate until a good alternative of Bitcoin pops up.

You mean like an international money wire, where your payment is routed through unknown banks who each take their own random fee before it gets to its destination a week later $50 lighter, and you have to fill out the FinCEN AML paperwork. Don't send multiple payments under $10,000 either, or maybe they will all be "forfeited" for attempting to skirt AML laws. You might even have to leave your house.

Western union moneygram? US->US sending $1 costs $5.
796  Bitcoin / Bitcoin Technical Support / Re: confused about offline paper wallet on: November 19, 2013, 10:31:50 PM
The balance of your bitcoin address is public. The payments to an address and its balance are part of the public ledger that allows people to know when you have sent them a legitimate payment.

The ability to spend your bitcoins is only contained on the piece of paper.

Also, as much as black addresses are entirely unworkable, green addresses do actually provide a nice benefit.

Anyone who insists on being paid from a "green" address can start digging around the blockchain to try to find out how much BTC you're holding. Not such a benefit.

There's a blockchain based solution to providing a credible ID when making purchases in the works, designed by the Bitcoin main dev team. It's a far superior scheme to this green addresses nonsense.
I pay you, the money comes from the known mtgox green address and is deducted from my balance. How much bitcoin do I have? It's not how much bitcoin mtgox has.

You know that mtgox won't double-spend so you can immediately trust the payment. That's a green address.
798  Bitcoin / Bitcoin Discussion / Re: Bitcoin at the US Senate on: November 19, 2013, 10:09:51 PM
What they aren't saying is that Bitcoin is completely different than any centrally-controlled money or anything else called "virtual currency". Fake points in games, Apple store or xbox points, gift cards, Google wallet and payment processors, and such, are centrally controlled by a company who can go out of business or print their own.

Bitcoin has no central bank or authority. It won't go out of business. It can't be counterfeited (like US dollars are counterfeited when the Fed adds another digit to their balance and sends it to banks). I can send directly to another user with no interference. It is too good to fail.

I can be defrauded by giving dollars to a guy selling speakers out of his truck, who doesn't pay sales tax. So laws?

Why is Tunstall even there, she is from a law firm, and says Bitcoin won't succeed because it can't be regulated, transactions need to be tagged and not anonymous, and other bizarre stuff. Thinly-veiled banker?

The only interesting question was from Heitkamp, who asked about taxes and such, but in an "I already have my mind made up" statement way.
799  Bitcoin / Bitcoin Discussion / Re: Bitcoin at the US Senate on: November 19, 2013, 09:41:52 PM
Mercedes Kelley Tunstall - We need more law, less anonymity, it is used for money laundering, etc.

Regulation and seizing assets without trial has already driven Bitcoin businesses out of the United States.

Yay bitpay up now.
