Is there a way to see the hidden change addresses?

I want to put my balance into a read-only blockchain.info wallet and cannot get all of the BTC value into the wallet.  I do not want to have to browse all of my transactions using blockchain.info and figure which address(es) were the destination and which address was the change.

My deposit has been wired 16 days ago and still has not hit my bitstamp account.

Get verified.

Wire money.

7 days later, open a support ticket.

5 days later, get a reply asking for more personal information.

I reply in hours with passport and answers to questions about How did you learn about Bitcoin? / What is the purpose of your trading on Bitstamp?, etc...

4 days later, still no response.

It has been 16 days since I have done the wire transfer... I am SERIOUSLY concerned.

I would suggest that when a Satoshi is close to parity with a penny (either US, Pound or Euro they are all pretty close), then it is time to add more decimal places.  When 10 Satoshis = 1 penny, it is time to start considered and planning more decimals.

For Order of Magnitude, right now:

0.001 BTC ~= 1 dollar (or pound or Euro)

0.00001 BTC ~= 1 cent.

0.00000001 BTC ~= 1/1000 of a cent.  (A satoshi)

We have 1000 x value multiplier left until satoshi/penny parity.  It took 2 - 3 years for the last 1000 x value multiplier to occur.

We have 100 x value multiplier left until  10 satoshi/penny parity.  It took 1 - 2 years for the last 100 x value multiplier to occur.

Wire transfer to bitstamp on 11/20 with a support ticket opened 11/27.  Not deposited, no response from support.  This is the first time I have dealt with bitstamp.  Triple checked every detail & number for accuracy and my bank assured me on 11/27 that it has been sent.

What is the next step?

What is the next step?

In USD ...

Over the past few weeks & months, the Mt. Gox price has been ~10% higher than the rest of the market (bitstamp, btc-e, etc...).  Today, bitstamp is as high or just higher than Mt. Gox, and still 10% higher than the rest of the market.

What gives?

Hope we are as optimistic next year as we were last year

How would a community be able to use bitcoins if access to the internet and thus the bitcoin P2P network was either completely unavailable or only sporadically available from a small number of nodes?

Places such as Burning Man, remote villages and countries under civil strife come to mind.

There might have to be a level of trust for 0 confirmation transactions.

For example, would it be possible to create a separate, isolated bitcoin network with no mining and the disconnected network can get a trusted node to dump the latest block chain onto a USB stick every other day, and copy any information back onto the stick as needed (such as transactions).

What are the other ways to work?   Has there been any testing, design or thought put into this type of situation?

Has there been a public, in-depth, 3rd party review of the standard bitcoin client?  I have experience with software engineering... an industry average is at least 1 bug per 1000 lines of code.  The bugs might be trivial or critical, easy to spot or hard to discern or activate.  I am NOT saying that the people who write bad code, but that programs are written by humans, and even the best of us make mistakes.

Kudos on the protocol fuzzing work that appears to be going on.

My copy is in C:\Users\{myname}\AppData\Roaming\Bitcoin

I would shut down the client before copying.

Nothing yet.  Replied to their e-mail from Wednesday and opened another "Contact Us", still nothing.  I have written it off, not worth the $0.11

Used coinapult.com last week - seems like an interesting idea for simple payments and bring on new people... same person created satoshi dice, thought it was worth a test.

Sent 0.001 BTC with 0.0001 transaction fee from my home e-mail address to work e-mail address.  After 2 hours and 18 confirmations of my transfer to coinapult's address, no e-mail showed up at either location, even checked the spam folders.  Contacted support and they said they would not be able to get to it tonight but fix it tomorrow - no problem, it is a beta site.   3 days later, still nothing - e-mailed support again, no response after 30 hours.

Its a shame as it seemed like a valuable service - send bitcoins to an e-mail address... veterans can just send it to their wallet, and newbies would be guided on how to setup an online wallet.

I lost 0.0011 BTC, please let this 11 cent lesson help you not lose your bitcoins.

Check this. 7 GB growth in the last 12 months.

http://blockchain.info/charts/blocks-size

At this rate, 20 GB will be in 2015 or 2014.  Someone bringing a new full client online could take days - header only clients will increase in popularity as the block chain grows.

At least the rate of growth seems to be constant.

I bought $2,000 during the first boom in 2011 - when BTC went from $2 to $30 to $5 in about 6 months.  I bought in around $18 average when it was going down (catching a falling knife) and kicked myself when it went all the way to $5.

Instead of selling at $5 to get some money back, I "wrote off" the money and would check the price every few months or so.  Saw an article in March 2013 about someone selling their house for Bitcoins and figured I would check the price - $66!!!!?! 

Sold half immediately at $67 and sold little bits more on the way up to $140.  I was ecstatic, I had 10% of my original Bitcoins and a handy profit.  But I kicked myself when it kept going up....

Bought and sold a bit quickly a few times (e.g. buy at $150, sell at $170), and my last quick hit almost worked (bought at 188, sold at 25% at $238, $248, $258, $268) the last sell was just $2 over the top.  Wound up getting out at $150 for an overall profit.

Now I just did a quick hit today - buy at $63 - sell at $68.

My best returns are when I put in a little thought and make an immediate buy and future limite sell at one time and walk away - never checking the price. 

The max value between now and 2014/04/05 will be $1000 +/- $200.

The actual price will be $687... +/- $687

I am going to write my own bitcoin client - I have started reviewing the standard client code.

My sequence of goals are:
1. Create a client that can create keys & addresses and store them.
2. Using a standard client, send a small amount of BTC to the created public address.
3. New client creates "offline" transactions to send the BTC back to a standard address.
4. Manually review the transaction, copy transaction over to a standard BTC client and transmit it to the network.
5. Think about connecting to the bitcoin network.

Here is a list of capabilities / methods I want to implement to manage keys & addresses, am I missing any?

Entropy -> Private Key
Private Key -> Public Key
Public Key -> Public Address
Private Key -> Secret Storage (custom wallet)
Secret Storage (custom wallet) -> Private Key
Public Address -> Storage
Storage -> Public Address
Public Address -> Public Key


What are the methods needed to create transactions?  Is the blockchain needed?

It looks like one of the bitcoin console functions would handle the transaction - which one(s) can be used if the transmission does not come from the client's wallet?
sendfrom
sendmany
sendrawtransaction
sendtoaddress

{"result":"success","return":{"lag":1639187331,"lag_secs":1639.187331,"lag_text":"27 minutes"}}

Its dead Jim!

I have done a bit of homework and have a CS/math degree.  My field is not crypto, but I know about fields, groups, graph theory and SHA-256.  Any answers, review or corrections of my questions would be appreciated.

What is the maximum number of private addresses?

2^96  --  https://bitcointalk.org/index.php?topic=24268.0

and "almsot 2^256"   --   https://en.bitcoin.it/wiki/Private_key


What is the maximum number of public addresses?

Only max found is 2^192 from  --   https://en.bitcoin.it/wiki/Private_key

25 byte public address  minus 1 byte for 00 hardcoded first byte  --  2 ^ ( 24*8 )


Has it been proven that there will be no hash-collisions where 2 private addresses share the same public address?


No info found.


What is the process to create a private and public address ?

The address creation process looks like a random private first, then generate public address from the private...

It looks like there are Process to create a public address from a private address:

3 SHA-256 hashes and 1 RIPEMD-160 hash, plus some other simple manipulation.

https://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addresses


Assuming a public key is generated from a private key, how does it computationally compare to block creation?

Creating a block needs 2x SHA-256.
Creating a public key needs 3x SHA-256 + 1 RIPEMD-160.
RIPEMD-160 is 2xMD4 hash, each of which is less than or equal to a SHA-256  hash

Thus a public key is ~ 5 hashes and a block is ~2 hashes.

Pretty alarmist for rather vague language - will have to see what comes of it.  If a bank is running out of capital, there are
1. Government cash for assets, stock or debt.
2. Private cash for assets, stock or debt.
3. Depositor's money.

The statements say that they want to create a system to fix under-capitalized banks - but not do #1.  The lack of private money to buy bank debt (#2) is often the main cause of the capitalization issue.

There are many ways for the government to fix this problem - here are some examples.

a. Make the banks have more capital (more regulation).
b. Allow banks to easily sell large assets (e.g. subsidiaries) to private investors to raise cash.
c. Allow banks to seize depositor's money.

Only option a is called out.  Options (b), (c) and possibly others are not called out explicitly - the "worst" statement is:

"This regime will be designed to ensure that,
in the unlikely event that a systemically important bank depletes its
capital, the bank can be recapitalized and returned to viability through the
very rapid conversion of certain bank liabilities into regulatory capital."

Banks have many liabilities, including depositor's money.
