I'm generally an empathetic person person even if I don't act like it but when you actually look at the situation rather than going "Boo hoo that poor victim" I find it very hard. For one thing as people have already spammed in the comments of this article he got a 15 year old girl pregnant so he isn't exactly the shining beacon of intelligence and responsibility. For those internationally especially in America this is the kind of shit we have to put up with in the UK on a regular basis and the amazing thing is throughout all of it they manage to act completely indignant about the problems they have and blame everybody else so if you think we're being mean it's because we've seen it so many times we're wondering why the hell people don't learn.

Kinda sad how deliberately Bloomberg misinterprets the news from China, calling it a 'ban', and people shouting how China 'rejects' or even 'forbids' Bitcoin.

They're mostly just making people aware of the fact that it's not an official currency, and warning about the risk it bears when trading in it.

Here's an article that puts things in better perspective: http://www.techinasia.com/panic-chinas-regulation-bitcoin-leaves-room-optimism/

So get a grip, you panic-mongers

(blockReward/difficulty)*((mhs*1000000*86400)/(POWER(2,48)/65535)) = btc / day based on pps

difficulty * 2^32 = average number of hashes required to solve a block.

Both values express the same concept in different form.

difficulty = 2^256 / (target * 2^32)

Why is this not the same value are the one reported in mining software, such as CGMiner, it reports 707M. All websites also list it as 707M and not the number above.

For the sake of Crypto world, some well known devs BTC/LTC and others need to take a look at Quark because it really is having some interesting features and the experiment of mining them all quicker than decades might turn out positive after a while. The devs of other coins need to stop being selfish and acting like they are in some kind of currency war and help hand because we are seeing improvements above BTC and LTC in these coins which deserve more attention and if some flaws get fixed we could get a top notch currency here.

I recently found the private key from a wallet from 2010 when I generated a block of 50 bitcoins.  I imported that key into blockchain and the 50 coins showed up in my online wallet.  However, whenever I try to send coins, I get an error message: invalid signature.  I used the blockchain web interface from a PC for these transactions.  What's up with this?

I'm installing bitcoin-qt and currently waiting it for it to sync.  Should I try to import the private key there and see if that works?

I've read vague warnings about importing private keys, but nothing specific.  Can anyone provide details on the kind of dangers should I watch for?

Thanks

Cex.io supports merged mining.
What altcoin do you need?

None of the major analysis tools find malware on "listentobitcoin.com".

Comodo: http://app.webinspector.com/public/reports/18708129

This sounds like a scam to get people to switch to "bitlisten.com"

Hi everyone,

I'm trying to optimize the blockchain files.

What I found is interesting.
So for one thing is obvious - protocol is not optimized.
Why?
Well you have distinctive lengths IN the protocol description, and for some reason you still need the block length AND the delimiter (not to mention that the lock time might as well be a delimiter).

But first things first, the only descriptive information about the blocks I found is in this page http://james.lab6.com/2012/01/12/bitcoin-285-bytes-that-changed-the-world/
But it does not state the format of target bits field is it a varint or just a regular 4byte int?

For now you can safely delete the fields of of network id in the blockchain data as well as block length, sequence number and lock time.
Save the timestamp as difference from previous block - this can yield additional optimisation for 4 bytes in keys.
That frees just 16 bytes per block which is not too much, but I want to delve deeper into relations in the script of bitcoin transaction so we can build a relation database first to see how everything is connected and then just optimize by the lower numbered sequence of keys (the latter is obvious various hashes).

I'm doing this for fun, and not sure a drastic optimization can be done, but it's funny that no comprehensive network protocol and file format description exists in the wild.
