To be honest, I'm not sure they upgraded anything.

This is ridiculous.

Now if we all calc how much time we spent dorking around with bitcoins compared to profit i imagine i have made about 1.20 an hour :-)

Heh, I think that's a hugely optimistic figure... Smiley

I put in about $4000 USD overall (combination of mining equipment & bitcoin purchases in 2011/2012).

A couple grand here invested in mining gear still chugging away.

No use crying over spilled milk thinking how much every coin you mined would be worth today. Better to think about the next goal or way to make money!  if i dwelt on evey time i should have held instead of sold my list would be endless. From collectibles, antiques, precious metals, stocks, etc... Any profit is good. Just keep trying. And sometimes selling was hugely smart. One never knows.

Who said anything about crying?

I never sold any coins until recently during the run up, but I'm thrilled with both the profit I currently have as well as the number of coins I'm holding on to long term.

You have to create a wallet first, and then select the wallet into which you want to import the keys.  From the wallet properties, there's an option on the bottom right for importing private keys.

Unfortunately, there is no way to import public keys into a watch-only wallet.  There's a couple reasons for this, and not all of them are laziness Smiley


I just realized that you can't import private keys in to an offline wallet.

I created a new wallet and now the option shows up.

Thanks!

Where is the option to import private keys? I saw various pages mentioning that it is located in the wallet properties page but I can't seem to find it.

Also, is there a way to import a public key as a "Watch only" type of address?

This site is completely broken...

It made me hit repeatedly when I only clicked hit once, it made me stand after only taking one hit and it even changed the cards (both me and the dealer) twice after hitting/standing...

I only lost 1 btc but let this be a lesson to others...

Re: Maximum number of Mhash to solve a block.

on 07/07/2011, 21:34:50 UTC

Also, solving a block by hand means that you need to calculate sha256(sha256(block of transactions + nonce)) where the hash conforms to the current difficulty... Keep in mind that all miners (combined) are currently trying 11197.84 GHashes/sec. It would take longer than the rest of your life to complete by hand.

sha256(sha256(block of transactions + nonce))
Can you explain exactly what that is,or where to go to find out.
And as far as longer then the rest of my life, I am quite aware.  It is just I find knowing how to manually do it is understanding it.


SHA256 is a hash (or compression) function (see here).
The transactions are people sending btc to each other (signed with their private key).
A nonce is basically a random value.

Basically, a block contains a list of transactions plus a nonce. The SHA256 function is calculated twice. Once on the list of transactions + nonce and once again on the output of the first SHA hash.

The difficulty requirement is that there are a certain number of leading zeros in the output of the SHA function. Miners basically take a list of transactions, and do the above calculations, only changing the nonce each time. Eventually, someone will get lucky and find the correct nonce so that the output of the chained sha256 functions has enough leading zeros. Once that happens, that block is considered solved and work begins on the next block.

I did not know that.  So if I understand you correctly, although every block has a solution, it is theoretically possible (Although insanely unlikely) that a solution will never be found?
Or does this mean that I can never be given my "Own" block to solve, and there will always be others working on it even if I am solo mining, thus it is guaranteed that the block will eventually be solved, but whoever solves the block gets all the bitcoins?

Now that we have broken the ground on how this works a bit, is there a place I can go and read a bit about this more technically, but written for the average joe to understand.  Basically I am not looking for the information on where a block comes from, and exactly how you go about solving it so that I could in theory, if I had nothing better to do with my time solve a block by hand. (Yes, I understand this is absurd, but if I know enough how to do it on paper, despite the fact it may take me the rest of my life to do but a single hash, or not, I will understand exactly how it works.)  Its more for curiosity.


You aren't given your "own" block to solve - it just comes down to who in the network is the first to solve the next block. Once someone solves it, the entire network moves on to solving the next block.

Also, solving a block by hand means that you need to calculate sha256(sha256(block of transactions + nonce)) where the hash conforms to the current difficulty... Keep in mind that all miners (combined) are currently trying 11197.84 GHashes/sec. It would take longer than the rest of your life to complete by hand.
