Let's add up the KNOWN lost bitcoins

[cypherdoc]

kjj, how'd u find the block?

I just clicked back through the chain until I saw a 9000 -> 8999 + 1 transaction around the right date.

i assume u did this in Block Explorer.  just went there and they only have the last 20 or so blocks listed?  how'd u search further back?  also how did u know what date the block got solved?

You can click all the way back to the genesis block by using the Previous Block links.  Stone Man posted about the loss here on the forums the next day.

geez, u clicked back almost a year?  sounds like u had to remember that Stone Man posted here on the forum, search back for the post and date, and then u knew about how far back u had to go.  the point i'm trying to ascertain is if u didn't know that info and u were looking back in time for this tx, u would have to patiently click back and examine each block carefully for that 8999.  altho in this case it is easy to spot.  what if u were looking for some .01 btc tx?

It's only like 50,000 blocks back.  OCD hath its privileges.

His loss was pretty easy to find.  There aren't many transactions like it.  Finding one specific .01 transaction would be a lot harder.  You'd have to look at something else that you know, like one of the addresses, or the transaction ID.

Not 100% sure, but looked like we lost a block probably due to default jgarzik's pool not retrying re-submiting work when bitcoind was unreachable...

Oh well. Fortunately no one else was mining at that moment. It was a very short round too with just like 500 shares... 

Lost blocks aren't truly lost. They are just not counted. Using a duplicate transaction hash in the generation transaction, though, WILL make them disappear.

If you previously had 1% of the supply, you now have 1.00054% (210,000 / (21,000,000 - 11,406.22) * 100)%

If you previously had 0.9994568% of the supply, congratulations, you now have 1%

I leave 0.01 btc in various wallets here and there

I may forget about one at some point.

May have deleted .01 off an aws ec2, and one when deleting a local vm.

My friend forgot his password, I think he lost at least 30.

I lost about 0.09.

I just lost about 4 btc on my broken hard drive... thank goodness most of my btc was NOT stored on that hard drive. I'm saving the hard drive, just in case this is one day worth thousands, and I'll be able to justify some data recovery thing.

In block 124724, I deliberately and specifically underpaid myself by 0.00000001 ฿, which is colloquially known as "1 Satoshi" after ฿'s creator and due to a lack of a good name for that amount of ฿ money.

To make absolutely sure that I was doing it on purpose, I set the reward value to 49.99999999, which meant that I inadvertently threw away the transaction fees which I could have allocated to myself.

I did it as a tribute to our missing Satoshi: we are missing Satoshi, and now the blockchain is missing 1 Satoshi too, for all time.

Before this, the total *awarded* ฿ would have been (assuming my calculations are correct):

฿20999999.97690000

Now, since I underpaid myself, the total *awarded* ฿ can only be:

฿20999999.97689999

--assuming everyone else pays themselves the maximum until the end of time.

So, this is a provably missing amount of the fees+1 Satoshi from the blockchain, from block 124724, which appears to be 0.01 + 0.00000001 ฿.

I did this by creating an option in my heavily customized client (derived from the git fork of bitcoind) which allows me to arbitrarily suspend the normal block reward calculation and underpay myself. The code itself only checks to ensure that I haven't *overpaid* myself. It doesn't at all care that I've *underpaid* myself.

I view this as a freedom in the protocol, and not a drawback.

blockexplorer.com has a display bug for that block which has not been corrected yet.
