Interested to know how much of the cryptocurrency coins (count BTC/LTC/PPC etc) that you have mined over lifetime you have sold/spent vs kept in cryptocurrency.  Do not include any coins you have bought, just that you have mined yourself or as part of a pool/consortium.  Dividends or gambling winnings do not count as 'mining'.

Clarifications for the purposes of this poll:

These count as 'selling/spent':

 - exchanged for fiat/national currency
 - buying goods/services
 - gambling losses

Do not count:

 - exchanging to another crypto-currency e.g. LTC
 - Investing BTC somewhere, but kept your investment as BTC (e.g. investing in BTC stock or BTC company) then don't count that as selling/spent.
 - lost/stolen wallets

[24 days]

Zerlan stated that there are several months to go before “we see the actual chips in hand” because the 28nm chips are still on the tape-out process but revealed that BFL are set to do what he described as a “bullet run”, which will produce a limited number of chips in 24 days (versus the normal 75-90 days required for a typical foundry run). This will not only enable Butterfly Labs to verify that the chips are working as expected but would also allow a small volume of customer orders to be shipped sooner than initially anticipated.

“The bulk run of chips should take place a few weeks after the bullet run, which is where many of the later orders will come from. That is expected to start shipping sometime in late January or early February 2014. As I get more information, I intend to keep everyone updated as much as possible,” Zerlan told CoinDesk.

counting back from mid-February, a 75-90 day 'normal run' will mean that it would start around end of November.  If this date is a 'few weeks after the bullet run' then the bullet run should expect to produce a few chips in early November, with the tape-out for the bullet run being 24 days before this, so around mid-October.

This does align with the timescales given by BFL before.  Those with very early Monarch orders should expect to get their product by mid-November.

Let the flaming begin.

really good panel discussion on Bitcoin.   I think Naval in particular was awesome in steering the conversation to talk about all the benefits of Bitcoin.  Very cool.

can we get an update from the mods on the status of bitcointalk.org?

It looks like the domain expired.  Is this anything to worry about?

Interesting - could this be used for mining?

[Note]

With bitomat losing their wallet, and bitcoins being lost as a result, this can potentially be solved by using the nLockTime field in the transaction.  See here under 'lock_time'.  This field allows you to specify a minimum unix_time or block count that the transaction won't be accepted into the blockchain before.  This is usually set to 0 by clients meaning that it is always valid.

What would happen is:

 - User deposits money in an exchange/bank, specifying the lifetime of the deposit (e.g. 1 month) and a 'return address'.
 - Exchange/Bank adds bitcoins to the users' account, and also returns a signed transaction to 'return address' with nLockTime set to the block or time matching the lifetime of the deposit.  User then keeps this stored transaction safe.
 - The exchange/bank can rely on the bitcoins remaning valid until the lifetime has been exceeded
 - Once lifetime is reached, the exchange/bank marks the bitcoins as 'invalid' and cancels any pending balance/bids/asks based on the deposit.
 - At this point, the exchange/bank can either automatically send the money back to the user using 'return address', or perhaps offer the the user the option of keeping the money in the bank/exchange by the exchange/bank moving the bitcoins to a new wallet with a new lifetime, resulting in a new transaction record the user keeps.  The old transaction record can now be destroyed.  Alternatively the user can withdraw the bitcoins merely by placing the stored transaction into the blockchain, or by withdrawing from the bank/exchange as normal.

The exchange/bank has no risk of the user withdrawing the bitcoins before the lifetime so can happily base bid/offer/balance until the lifetime arrives, at which point the bitcoins cannot safely be used because the user could at any time from then place the transaction into a block chain.  For support for part-bitcoin transactions (e.g. 10BTC deposit, with 0.1 BTC quantum) several pending transactions at different values (e.g. factors of 2 of satoshi) can be returned during the deposit.  (Note: For this split-bitcoin stored transaction to work, the exchange/bank would have to use a modified bitcoin client that pays txout change to the sending address.)

Note: This does not solve malicious exchange/banks since a malicious exchange/bank could just transfer the balance to another wallet and the stored transaction would never be accepted.

This is purely to solve the situation where a bank/exchange loses their wallet, then it's simply a matter of the user waiting until the lifetime hits then enacting the transaction(s).  This merely means that there would be a recourse for lost wallets e.g. bitomat.

Thoughts?

[No need to wait ages to download blocks, get your wallet balance on any Android phone in seconds!]

Hi,

I've written an android application that allows you to view your wallet balance on your android phone, without having to have a complete wallet stored on it.

It works by exporting your public keys from your bitcoin wallet using a command line tool.  You then place your public addresses in a repository, or on the SD card, then run the application on your android phone - import your public keys, and then goes to blockexplorer and adds up all the transactions to/from those addresses and presents you the result.  No need to wait ages to download blocks, get your wallet balance on any Android phone in seconds!



All the source is provided so you can check I'm not doing anything bad.  I also provide Windows/Linux binaries of the decoder tool.

The source and binaries are:

http://code.google.com/p/bitcoinwallet/

Let me know if you find it useful, or any issues you have - I haven't tested it with large wallets so I'd be interested to hear if people have issues with that.  Please read the FAQ for answers to most questions.

Backup your wallet before using this tool.  I do not accept any liability for wallet corruption caused by this app!!!

Cheers,

Will

1.  I generated a transaction with a 0 transaction fee and pushed that into the network - it hasn't been included in any solved blocks yet.  Will it ever be included?  Is there a way of sending it directly to a set of nodes (e.g. free transaction relay) so it might stand more of a chance of being included in a block? It was only 0.01BTC so it's more for academic interest than anything real

2.  If I run the bitcoin client and do not set it to generate i.e. it's not trying to solve blocks, then am I helping verify transactions?  My understanding was that I wasn't helping because blocks are only verified when the correct hash is guessed.  Am I right that all I am doing is serving as a relay for the p2p messages?  Only asking because people are saying you need to run bitcoin clients to keep the network working, but I thought that as long as pools are mining and including transactions in the solved blocks, the network can be fully 'kept alive' by pools just as well as lots of people running the official bitcoin client on their desktop.
