2  Bitcoin / Bitcoin Wallet for Android / Copy your own address to clipboard on: December 11, 2014, 01:21:01 PM
Is there a way to do this in the app? It's needed when you're trying to send funds to yourself from another wallet or exchange, or sending your address to someone via IM.
3  Bitcoin / Development & Technical Discussion / brainwallet.org offline transactions safe from reused R values? on: December 10, 2014, 11:45:41 PM
I've been using brainwallet.org's transaction tool (https://brainwallet.github.io/#tx) in a secure offline environment for spending paper wallets.

With the recent news I'm worried whether the tool could reuse R values. The source code is here: https://github.com/brainwallet/brainwallet.github.io/blob/master/js/tx.js
4  Bitcoin / Bitcoin Technical Support / tool to show address relation on: October 26, 2013, 02:03:57 PM
Is there a tool (similar to blockchain.info's taint analysis) that scans the blockchain and provides the transaction path(s) that connect 2 addresses that the user specifies?

For example I'd like to know if any coins originating from my addresses ended up on FBI's address and see the transactions linking them.
5  Bitcoin / Development & Technical Discussion / difficulty calculation on: September 26, 2013, 03:03:16 PM
If the next difficulty is calculated from the past 2016 blocks, does this mean that the time interval between the 2016th block and 2017th block is irrelevant?

Example:
block 2016's difficulty is based on the interval between blocks 0-2015
block 4032's difficulty is based on the interval between blocks 2016-4031

Does this mean that the interval between blocks 2015 and 2016 is unaccounted for?
6  Economy / Service Discussion / how does blockchain.info get the originating IP? on: May 12, 2013, 07:20:49 PM
I made a transaction with the qt client. Even though I had the client running for days and probably relayed thousands of transactions, blockchain.info correctly only shows that transaction originating from my IP.

How is this done, does blockchain.info try to connect to every single node?
7  Bitcoin / Development & Technical Discussion / coinbase transaction when block reward is 0 on: March 23, 2013, 10:52:00 PM
once all 21 million bitcoins have been mined, will a block be valid if its coinbase's output is 0 BTC (assuming there are no transactions with fees in the block)?
8  Bitcoin / Development & Technical Discussion / artificial 250kB limit? on: February 19, 2013, 12:50:53 AM
I've seen it mentioned on the forum many times that there's currently an "artificial" limit of 250kB per block, what does that mean, compared to the 1MB limit?
9  Bitcoin / Development & Technical Discussion / difficulty rounding on: February 05, 2013, 01:16:08 PM
On blockchain.info, the difficulty of block 219747 is show as 3,275,464.59 while the difficulty of block 219748 is 3,275,464.58656562.

How much rounding of the difficulty does the network tolerate?
10  Other / Beginners & Help / check balance of address without trusting block explorer on: December 26, 2012, 06:03:06 PM
How can one check the "balance" of an address without using a block explorer site - for example to verify if a paper wallet was funded successfully?
11  Other / Beginners & Help / incentive for nodes to propagate transactions on: December 26, 2012, 05:32:46 PM
What is the incentive for an individual node to relay others' transactions? It "costs" them bandwidth, so why do they do it?
