The nine year anniversary of the Bitcoin whitepaper being published reminded me of all the time I spent looking at the earliest portions of Bitcoin history back when I was in high school. The community has expanded a lot since then and so have my own skills so I figured I would go back and look at an early event that made history: that first payment of 10 BTC between Satoshi Nakamoto and Hal Finney.

The nature of the blockchain is that everyone can go and verify that this 10 BTC transaction actually took place. You can see it for yourself, right now, if you want. Here it is! You can see the date on it, 2009-01-12. The bitcoin network was merely a few days old at this point.

The 50 BTC this transactions spends is from coins mined to the address 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S. Now look at the recipients of the transaction: First is 1Q2TWHE3GMdB6BZKafqwxXtWAWgFt5Jvm3, which Hal Finney has said was an address of his. And then 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S again, which is Satoshi Nakamoto sending 40 BTC back to himself as change. If you look at the other payments in 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S's history, you'll see that Satoshi actually sent coins to quite a few people, probably from the cryptography mailing list, although Hal Finney (the first recipient) is the only one of them that has ever been identified.

Hal told Satoshi that he would send those 10 bitcoins back, but he had forgotten to do that before Satoshi disappeared. Hal was later diagnosed with ALS, and sold his bitcoins in mid 2013 to pay the medical bills. He passed away, proud of his influential involvement in bitcoin and cryptography in general, in 2014.

That's all pretty interesting. But, hold on, why did Satoshi choose to spend the bitcoins from block #9 in particular? Why not block 1, or block 100, or something? 9 seems sort of arbitrary. None of the other bitcoins that were confirmed at that point were ever spent.

I couldn't figure out the answer when I was young. But I think that I've found out now. The first version of the bitcoin wallet chose which coins were to be spent in a transaction based on the transaction ID the coins came from (actually by how many there are first, but in this case, all the transactions mined precisely 50 BTC, so that doesn't make a difference). The first payment to Hal Finney was in block 170, and newly mined bitcoins can only be spent after they have 101 confirmations, so only coins up to block 68 were spendable when the first payment happened. (Block 0 doesn't count, because the bitcoins it created are unspendable.)

I grabbed the transaction IDs for all the bitcoins mined from blocks 1 to 68 and sorted them. Sure enough, the coins from block 9 are right on top:

*nobody actually knows if Satoshi mined blocks 12 or 64, but they're here anyway to be sure


Here's another fun fact. The 10 bitcoins Hal Finney got from the first payment weren't his first bitcoins. He actually mined block #78, so he already had 50 BTC that he had made himself before Satoshi sent him that payment. In 2014, Hal actually released a screenshot of his earliest transactions:

In this screenshot you can clearly see both the 50 he mined originally and the 10 he got from Satoshi. (He kept mining for a while after that!) Block 78 has another unsolved mystery, though. Its extraNonce parameter suggests that the person that mined block 78 also mined blocks 73 to 77, as you can see by the upward slope that they make when you plot blocks by extraNonce:

(The higher slope up there are blocks mined by Satoshi, and block 64 being way down there is the reason that we don't know if Satoshi mined it or not!)

If we didn't know Hal mined block 78, and not blocks 73 to 77, we could infer from this chart a few things. First, Satoshi Nakamoto stopped mining after block 72, or restarted his miner, because the extraNonce slope ends there. Second, blocks 73 to 78 make a clear slope, highly suggestive that they were all found by the same person, be they Nakamoto or Finney, and in the same mining session. extraNonce can be wrong, and Hal claiming to have solved block 78 and not 73-77 suggests that it is. Is it just dumb luck that block 78 happened to look like it was on the same extraNonce slope as blocks 73-77? Why did Nakamoto stop mining right when Finney started? Additionally, there is a three hour gap between blocks 78 and 79. Why did Nakamoto wait for 3 hours after Finney stopped mining to start again? Was it just bad luck that it took so long to find a solution? These are unanswered questions. Feel free to speculate on what you think happened here!

Hopefully this was an interesting read, and happy bitcoin whitepaper anniversary!!! Smiley

Very interesting!
I checked address 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S and see that last payment 2017-09-05 14:38:11
After 2013 this address receive payment only.

Also interest fact, who use this address 1Q2TWHE3GMdB6BZKafqwxXtWAWgFt5Jvm3 now, if this own of Hal Finney? Last TX 2017-09-06 01

I read the whole thing and makes me feel so honored to be a part of crypto. But it is weird as the address 12cbQLTFMXRnSzktFkuoG3eHoMeFtpTu3S which you refer to as Satoshi Nakamoto's BTC address has been receiving payments form other addresses. Does this mean Nakamto is still alive or is somebody else is using his address. The payments were too small and also on 05/05/2016 there were 18 transactions of 0.00022 sent repeatedly to the address. Looks like somebody was spamming his address  Huh  The last payment sent from his address was 01/12/2009 Undecided Undecided Goosebumps

I can't solve any of the mysteries around Satoshi, but I enjoyed reading it.

The payments were too small and also on 05/05/2016 there were 18 transactions of 0.00022 sent repeatedly to the address. Looks like somebody was spamming his address  Huh
I think of it as knocking on his door. Very rich Bitcoin addresses also receive small transactions once in a while.

Very interesting and valuable for history of BTC,it's nice to know how it all started.I think it's really great that everything is so transparent and that it can be explored.I recently read post by Hal Finney from March 2013. and I have to admit that it really is very nice description how things started and his relationship with Satoshi Nakamoto.At the present time many are wondering what happened to Satoshi and whether that man actually existed,but there is one very nice sentence from Hal regarding Satoshi :

Quote
Today, Satoshi's true identity has become a mystery. But at the time, I thought I was dealing with a young man of Japanese ancestry who was very smart and sincere. I've had the good fortune to know many brilliant people over the course of my life, so I recognize the signs.

It is too bad that Hal has not been with us for a while,he will be forever remembered as person who made first payment with Satoshi and so he entered into history.

newly mined bitcoins can only be spent after they have 101 confirmations, so only coins up to block 68 were spendable when the first payment happened.

I think that the number of confirmations/blocks for which mined coins are unspendable was changed, but I can't remember exactly by how much or when. Not sure if it affects this analysis, therefore.

If we didn't know Hal mined block 78, and not blocks 73 to 77, we could infer from this chart a few things. First, Satoshi Nakamoto stopped mining after block 72, or restarted his miner, because the extraNonce slope ends there. Second, blocks 73 to 78 make a clear slope, highly suggestive that they were all found by the same person, be they Nakamoto or Finney, and in the same mining session. extraNonce can be wrong, and Hal claiming to have solved block 78 and not 73-77 suggests that it is, but I don't understand how this could have happened. Is it just dumb luck that block 78 happened to look like it was on the same extraNonce slope as blocks 73-77? Why did Nakamoto stop mining right before Finney started? Additionally, there is a three hour gap between blocks 78 and 79. Why did Nakamoto wait for 3 hours after Finney stopped mining to start again? Was it just bad luck that it took so long to find a solution? These are all unanswered questions. Feel free to speculate on what you think happened here!

Hopefully this was an interesting read, and happy bitcoin whitepaper anniversary!!! Smiley

Holy crap... This is such a weird coincidence. So weird in fact that it only really points to one solution; Hal WAS Satoshi. Why else would their mining times be so in sync with each other?

Nice presentation there OP.. Cool
That original wallet had only a few outgoing  transactions it seems:

32 Satoshi from the 50 was transferred to a total of 5 addresses.
1BBz9Z15YpELQ4QP5sEKb1SwxkcmPb5TMs contains 11 out of the 32 (Not touched since 14-01-2009)
1BDvQZjaAJH4ecZ8aL3fYgTi7rnn3o2thE contains 1 out of 32 ( Not touched since 12-01-2009)
1DUDsfc23Dv9sPMEk5RsrtfzCw5ofi5sVW contains 10 out of 32 ( Not touched since 12-01-2009)

[EDITED]
These 3 addresses account for 22 Satoshi out of the 32 ever moved. The next addres 1Q2TWHE3GMdB6BZKafqwxXtWAWgFt5Jvm3 had been silent since 2009 till it moved 0.034337 BTC to 1Nt1SwDjXmbF61XDq7vjA51hbUuzKU97Lq in june this year.

1Q2TWHE3GMdB6BZKafqwxXtWAWgFt5Jvm3 is the address that Hal Finney said was his according to OP. This had been silent since 2009 till it moved 0.034337 BTC to 1Nt1SwDjXmbF61XDq7vjA51hbUuzKU97Lq in JUNE THIS YEAR!!

This is the only address funded by original Satoshi Bitcoins that showed activity recently!!
WHAT DOES THIS MEAN? IS IT A BIG DEAL OR JUST NORMAL SATOSHI NAKAMOTO GANG..?? Cheesy
It means nothing. Hal left his Bitcoin to his family so they have control of his private keys. It is likely that they are only now figuring out what to do with his Bitcoin and how to move it around.

Now i feel bad about my post. It feels unnecessarily sensationalized. I apologize.. Just wasted that time to navigate and come to a stupid conclusion. Hope everyone in the family isl doing good.

The payments were too small and also on 05/05/2016 there were 18 transactions of 0.00022 sent repeatedly to the address. Looks like somebody was spamming his address  Huh
I think of it as knocking on his door. Very rich Bitcoin addresses also receive small transactions once in a while.
I like to call it background noise in my head. Addresses that are interesting for some reason or another always seem to have it, collecting dust like ancient treasures. Maybe I will post about that next.

Blocks 73 to 77 seems to be mined by Satoshi.

Block 78 was mined by HAL.

My hypothesis is that Satoshi was looking at the debug log on real-time. When he saw that a block had been mined by another person he decided to restart his node (blocks 79 to 125 are his).

/tx/0437cd7f8525ceed2324359c2d0ba26006d92d856a9c20fa0241106ee5a597c9]look at when those 50 bitcoins were mined to that address[/url] you can see that it came from block #9, and blocks 1 through 14 were mined a day before the bitcoin software was even released (meaning, technically, bitcoin had a 700 BTC premine!).

wtf.

Block 1 has a timestamp of 2009-01-09 02:54:25.   The announcement of Bitcoin's release is timestamped Thu Jan 8 14:27:40 EST 2009, which is more than 7 hours before block 1.


Please fix your post before we have to endure more years of people repeating unsupported speculation and outright untruths about the history of Bitcoin.

None of the other super-early Nakamoto bitcoins were ever spent.
You have no idea which if any other blocks he mined, -- the only reason you think you do is due to garbage "scholarship" like your own that can't even manage to compare two dates.

I'd written, years ago, in a notebook that the release was on 2009-01-10 21:22:01. You're right, that's an error, it's actually the timestamp of Hal Finney's first reply that I'd mislabeled. With this in mind I had thought the first 14 blocks after the genesis block were made beforehand because of the 24-hour gap between 14 and 15. I'll fix that part of the post. Embarrassed

We attribute early blocks to pseudonymous miners by looking at the extraNonce parameter in the coinbase transactions of those blocks. Blocks 1 to 11 appear to have been mined by the same session incrementing extraNonce, and up until block 78 every block follows that same basic pattern with no interruptions except for two unspent blocks.

Well, there are some extraordinary facts about this:

1. Satoshi's address is still receiving transactions. Maybe donations? Or maybe just naive attempts to make him know we don't forget him...
2. Satoshi sent his first transaction to Hal Finney, but why this? Why sent to him? My speculation is that Satoshi and Hal worked together or even they were the same person! Such speculations are confirmed by this:




If we didn't know Hal mined block 78, and not blocks 73 to 77, we could infer from this chart a few things. First, Satoshi Nakamoto stopped mining after block 72, or restarted his miner, because the extraNonce slope ends there. Second, blocks 73 to 78 make a clear slope, highly suggestive that they were all found by the same person, be they Nakamoto or Finney, and in the same mining session. extraNonce can be wrong, and Hal claiming to have solved block 78 and not 73-77 suggests that it is. Is it just dumb luck that block 78 happened to look like it was on the same extraNonce slope as blocks 73-77? Why did Nakamoto stop mining right when Finney started? Additionally, there is a three hour gap between blocks 78 and 79. Why did Nakamoto wait for 3 hours after Finney stopped mining to start again? Was it just bad luck that it took so long to find a solution?

3. I'm also astonished about transaction fees! ZERO! I didn't know first Bitcoin transactions were basically free...
