Historical question: were any Bitcoins premined? If so, how many?

[forbun]

And where can I verify/see this? On the blockchain?

Did Satoshi release/open source Bitcoin publicly on the same day that mining began? Or was it some time later?

Where did he make the announcement/initial release?

The genesis block: http://blockchain.info/block-index/1

The original 50 BTC are still sitting there unused, along with over 10 BTC random people have sent to "Satoshi" over the years. I wonder if he even has the private key to that address.

[CIYAM]

AFAIA the coinbase from the Genesis block cannot be spent - so it really couldn't be considered "premined".

How interested might you have been in the following drawing?



At the time it was drawn, not many people were interested.  It did eventually make it into a publication though.

That was drawn by Charles Schulz, creator of Snoopy, when he was a child.

See back when Satoshi created Bitcoin, almost nobody gave a rat's ass about it.    It was a lot of work, from what I read, to try the program out.  The code wasn't easily compiled and built, there was nearly no documentation, etc.

But the project had been discussed in the cryptography mailing list months prior to the genesis block being created on January 3rd, 2009, and the first public release occurred less than a week after the genesis block was mined:

Eventually, others did join in.    

The June 2010 Slashdot article is when difficulty rose above to where there were more miners (maybe a few dozen prior to then mining regularly?).  Difficulty was 1 until February 2010 at block 38,304 -- when 1.9 million BTC had already been mined.

Did Satoshi release/open source Bitcoin publicly on the same day that mining began? Or was it some time later?

Where did he make the announcement/initial release?

As proof that the blockchain was not pre-mined, the manually created genesis block included a January 3 2009 headline from the Times UK:
"Chancellor Alistair Darling on brink of second bailout for banks".

The release announcement was on January 9 2009:

http://www.metzdowd.com/pipermail/cryptography/2009-January/014994.html:

Announcing the first release of Bitcoin, a new electronic cash
system that uses a peer-to-peer network to prevent double-spending.
It's completely decentralized with no server or central authority.

See bitcoin.org for screenshots.

Download link:
http://downloads.sourceforge.net/bitcoin/bitcoin-0.1.0.rar

Windows only for now.  Open source C++ code is included.

- Unpack the files into a directory
- Run BITCOIN.EXE
- It automatically connects to other nodes...

Then we see from the timestamps of the blockchain that mining started after the release announcement.

It's probable that the time between Jan 3 - Jan 9 was testing, likely including several days of discarded blockchain mining before Satoshi decided to release.

The code wasn't easily compiled and built, there was nearly no documentation, etc.

Intro
-----
Bitcoin is an electronic cash system that uses a peer-to-peer network to
prevent double-spending.  It's completely decentralized with no server or
central authority.


Operating Systems
-----------------
Windows NT/2000/XP (and probably Vista)

Vista hasn't been tested yet.  All the libraries used are cross-platform, so
there's nothing preventing future Linux and Mac builds.


Setup
-----
Unpack the files into a directory and run bitcoin.exe.

The software automatically finds other nodes to connect to.  You should set
your firewall to forward port 8333 to your computer so you can receive incoming
connections, otherwise the nodes you can connect with will be limited.

To support the network by running a node, select:

  Options->Generate Coins

and keep the program open or minimized.  It runs at idle priority when no other
programs are using the CPU.  Your computer will be solving a very difficult
computational problem that is used to lock in blocks of transactions.  The time
to generate a block varies each time, but may take days or months, depending
on the speed of your computer and the competition on the network.  It's not a
computation that has to start over from the beginning if you stop and restart
it.  A solution might be found at any given moment it's running.  As a reward
for supporting the network, you receive coins when you successfully generate a
block.

[Stephen Gornick]

Ha, Windows.  That's probably why I remember reading that it was a little bit of a hassle early on ... for Linux and Mac users.

The code wasn't easily compiled and built, there was nearly no documentation, etc.

Correct-a-mundo.

A write up on the genesis block is of course here:  https://en.bitcoin.it/wiki/Genesis_block

Boy I think the Genesis block is probably the most visited page over at blockchain.info.  When i first learned about it my imagination ran wild.  And i think it's awesome that people are donating BTC to the idea of Satoshi - though they will likely end up as "lost" bitcoins in the end.  I think Satoshi (whoever he/they are) intentionally made it so this first block was un-spendable, though i tried to figure out the "quirk" they speak of and my brain exploded.

I wonder if the funds that people have given Satoshi's address since then *might* be spendable or if the first block sort of poisons the whole address which depends on it?  So everyone keep an eye open - if anything from Satoshi's address ever gets spent one day then it means the creator is alive!!!  (muahahahaha)

[DeathAndTaxes]

The genesis block wasn't ever "intentionally" unspendable.  It was an oversight however if future versions of the client "fixed" that oversight and earlier versions didn't then it would hard fork the network.

Technically it could be "fixed" in a hard fork "safe' manner but given the limited impact it likely never will.

Aaah, thanks for the info, points me in a good direction to learn more.

So then the question is how many Bitcoins are still sitting there from those days?

Even beyond the genesis block. How many were mined by very early adopters and are still just sitting there? If it's in the millions, it could have serious consequences of those are ever released into the Bitcoin economy.

[forbun]

blockchain.info shows some Public Notes for transactions sent to the genesis block's newly-generated coins' address, e.g.

Public Note: A Satoshi for Satoshi, may it be worth hundreds one day.

Where are those notes from? Are they in the blockchain? How do I make one?

[Stephen Gornick]

Where are those notes from? Are they in the blockchain?

No, the third-party blockchain reporting service, Blockchain.info, stores those "public notes" and displays them:

 - http://bitcoin.stackexchange.com/q/4707/153

How do I make one?

What are public notes?
Public notes are embeddable short messages during the transaction. An example of a public note can be seen below:

Only the coinbase transaction (block reward) is (currently) unspendable, anyone sending coins to the address creates a spendable transaction like any other.  Assuming Satoshi has the private key.

Thanks for the info, but could you please explain how you learned this?  I'd like to understand more deeply as my imagination totally envisions the idea of Satoshi turning into a religious cult 100 years from now if Bitcoin is still around.  Like tossing coins in a fountain - flip Satoshi a few satoshis.  I've read Satoshi's paper of course but the implementation in code is probably in a git repo somewhere and I don't frankly have time to read wallet source code.  Then I probably wouldn't pick up on the mechanism that causes what you describe if I did read said code.

Tangentially...  That private key must be siting somewhere...  Would make headlines if any coin is ever spent from that address - like the Loch Ness Monster being alive.  Or perhaps 500 years from now it would become one of the biggest enigmas and they'd make documentaries about the mysterious Origin Block (capitalized of course).

One can dream right?

And nice nickname - now i know why it was in use when i tried to sign up with it!

Well, I just understand how bitcoin works, and have read around / looked at the source code

The code that checks the inputs of a txn looks them up in a hash table by the txn hash, and if it's not there the txn is rejected as invalid.  The genesis coinbase (the first txn in the system and hardcoded - you can perhaps see why it was missed) isn't in that hash table, which was an oversight in the original code and preserved in subsequent changes.  Later payments to the address are nothing special and just txns like any other, that are entered in the hash table, and hence spendable.

Ding - lightbulb moment.  Now it makes much more sense.  At least I think it does..  (heh)

So if I got it right, there might be a few different ways to make genesis spendable...  But since inserting a valid hash would mean a) finding a valid hash - probably computationally impractical - and then b) recomputing the entire blockchain since the instant it was created (lol!) whatever way might be used would essentially require a "we love you satoshi" exception rule in the hash checking where the code skips the prior transaction hash check if a valid spend request appears which demonstrates that the genesis block's reward owner has the right private key.

Gads.  Well IMHO we should just leave it there.  Let him/her/them have the tips that grow on the side. 

Thanks much!

Making it spendable is easy - just add the txn hash to the lookup table.  The problem is any new client doing that, and then permitting the coinbase to be spent, would be incompatible with older clients that don't permit it to be spent, leading to a chain fork.

Litecoin and Feathercoin also pre-mined. litecoin.tumbler.com admitted to this now gone and Feathercoin openly admits to this.

[ShameOnYou]

yeah the early alts were premined generally, 2011 coins

much of the early mining.... well know whos really who did it? i suspect btc was certainly premined to a huge extent
