41  Bitcoin / Bitcoin Discussion / Let's trace Satoshi's 50 BTC on: April 25, 2014, 03:01:15 AM
Well, in my last article I wrote about the only bitcoins satoshi spent and where they wound up. Well, now I want to narrow that down further and answer the golden question:
Do you have any of satoshi's bitcoins?

Before we get off hand, we need to establish first the traceability of bitcoin.
Bitcoins as a number are traceable, but not exactly as a material.
Satoshis, the consensual named smallest division of a bitcoin, are analogous to atoms in a way that they cannot be divided further. However, we cannot trace individual satoshis back. See the figure below:

Say someone mines Block A and Block B, each worth 50 BTC. Then the miner concatenates the coins to one output of 100 BTC, possibly at a new address. If the miner was to split the coins up again into two 50 BTC outputs, you could look at one or the other but you couldn't tell me which block they came from; A or B. We know they came from one of those two blocks, but not which.
Let's say we could dye the bitcoins from Block A another color, like red, and we'll make the coins from Block B colored blue. We'll assume that when coins from each block are mixed, the dye is as well.

So, as we can see, the 100 BTC when split back up can neither be identified as red or blue, but instead purple, which is 50% of each. It's not that each output has 25 RED BTC and 25 BLUE BTC, but the coins themselves are all PURPLE BTC, down to the satoshi. If we took one satoshi out of one of the new 25 BTC outputs, it would not be from either Block A or Block B but both. The satoshi exists because of both blocks. In this case, 50% of each block.

Now, let's look at the REAL bitcoin block chain and trace satoshi's coins as far as we want.
We'll leave bitcoin outputs colored WHITE. Then we'll dye satoshi's bitcoins GREEN. We will define bitcoin royalty as how "green" the coins are.
Let's have a look. If you remember from my previous article, satoshi only spent the bitcoins from block 9, so we'll only be looking at those.

Above is the 50 BTC from block 9. We can see here the first transaction, where satoshi sent 10 BTC to Hal Finney as a test.
We'll look at those ten bitcoins more later. First though let's keep tracing the 40.

Now we see satoshi continued his spending spree, sending 10 BTC to an unknown individual and then 1 BTC to another. Those bitcoins are 100% royal (green), but have not been spent since 2009. Perhaps someday they will be, but for now they aren't going anywhere. Let's see where the next 29 BTC go.

This is where satoshi's spending ends. The remaining 18 BTC still belong to him. His last two expenditures have sent out a 1 BTC output and a 10 BTC output. Yes, they've been spent! Let's have a look at where they went.

Looks like the 10 & 1 BTC outputs belonged to the same person who mined block 360, because they went and mixed the three outputs together. 50 + 10 + 1 = 61 BTC, and that 61 BTC output is 18% royal. Like satoshi's 18 BTC output, This person's 61 BTC output remains unspent to this day. It's a $30,000 fortune asleep on a hard drive somewhere.

But we all want to know. How "royal" are MY bitcoins?

Well, every single royal output we've analyzed up to this point is left unspent. You know, except the one that was Hal Finney's 10 BTC received from Satoshi. Those 10 BTC account for all royal bitcoins in circulation today, so let's have a look at those.

Those ten bitcoins have quite the adventure. I'd go through the whole thing, but it's rather extensive. If you're really interested you can see my previous article:
However, I will take the liberty of cutting to the chase; That is to say, where the bitcoins are first mixed in with non-royal coins.
Eventually, all those ten coins arrive at these outputs:

1.69 BTC from Hal's ten are unspent today. However the remaining 8.31 BTC - across seven outputs - were mixed with non-royal coins!
We'll be looking at each of them separately. Let's start with the first spent one on the left.

This one was mixed in with a 0.01 BTC output. I've confirmed that this particular output was of 0% royalty by tracing it as far back as possible. It was painstaking and I'm probably going to get tendinitis, but the 0.01 BTC was a faucet dispense. In fact, the dispense was from Gavin Andresen's faucet, whose money came initially from mining.

Well, I could keep tracing this coin for a while, but it'll take some time. So, I hope you'll let me have that.

I will release another article in the future, including how to determine the royalty of your coins.
I think it'd be a pleasant surprise to learn your wallet holds some of satoshi's coins.

Hello bitcoiners!

Let's say I want something like this

But of smaller size. Is that possible? I'm on a very tight budget but I'd like to see if I can get 32-160 of these laptops -- in green plastic -- 10mm wide, instead of 20mm, other dimensions scaled on the same aspect ratio.

Can someone give me a thumbs up and a price tag?

Just creating a poll to see just how many people know about multisig addresses.
They seem really, really, really great for security but I almost never see them on the blockchain.
48  Bitcoin / Development & Technical Discussion / Satoshi only spent 50 BTC. Here's where those coins are now on: March 29, 2014, 06:48:27 PM
Now, citing Sergio's research, satoshi mined a lot of BTC. In fact, almost (or exceeding) BTC1,000,000.
He has a distinct pattern of mining, and only one block that is confirmed to belong to satoshi has been spent.

Below is a representation of the 50 BTC from that one block -- block 9 -- as they were just after being mined.

I've traced -- by hand -- where every single one of these coins have gone. See the chart below:
Green = Unspent, Gold = Spent Go packers

Now we've all read that the first p2p transaction that occurred was satoshi sending Hal 10 BTC as a test.
You can see this transaction above. It's the original 50 BTC splitting into 40 BTC and 10 BTC outputs.

He later sent 10 BTC to someone else, and then he sent 1 BTC to someone, and then he sent a total of 11 BTC to the same pseudonym,
which in my chain archaeology thread is referred to as Bbz. Bbz mined block 360, and then combined the coins from that block with the 11 he got from satoshi. Unfortunately, Bbz is no longer with us-- they vanished long before satoshi did. Maybe one day they'll find their 61 BTC and return to us.

Satoshi still has 18 BTC from this block.

The 10 BTC Hal got were probably donated to a couple organizations but I didn't look too far into it.
There's 1.69 BTC there left unspent. It's possible they belong to Hal, or a friend of his.

Two of the separate coins were mixed in with thousands of others into huge whalewallets.

That leaves 6.31 BTC. Well, they're still moving today, and it's highly probable - unless your bitcoins are brand new - that there's a little bit of satoshi nakamoto's bitcoins in your wallet Grin

Here are those 50 BTC split up accordingly:

As the first block ever spent (and for several days 100% of circulating bitcoins) it's interesting to see where all the coins wound up, and nice to know that we all probably have a little of their taint. Smiley

I'm making a bitcoin-related game Smiley
In order to make it more diverse, I'd like to include references to actual things we see on the forum, like your small business or your dice site.

You can pay as much as you want for one of the ten slots; I'd rather not disclose many details of the game yet.
By "as much as you want," I mean 0 or more BTC. I'd be perfectly okay accepting 0 BTC bids, but higher bids will be accepted first.

Edit: It's a board game. Two to (at least) four players.

52  Bitcoin / Bitcoin Discussion / So, what does a bitcoin WEIGH? on: March 15, 2014, 07:09:32 AM
How can something as abstract as a bitcoin have any weight? It's just a number next to your name, isn't it? Well, think about your hard drive, on which your qt client sits. Imagine you have 100 GB of porn on it (you sick bastard). Well, as a pure file, your hundred dirty gigs take up physical space on your hard drive. Ultimately we can break down 100 gigabytes into a lot of bits. A bit is either a 0 or a 1; and your hard drive keeps track of them all. This eventually comes to create your files, in this case your exotic porn which is probably illegal somewhere on earth. The difference between the 0s and 1s is that the 1s have added weight, rather than just the empty 0s. For a 0 to be a 1, it has to receive an electrical charge. The electrons that compose this charge are (as cited by several sources) about forty thousand strong. Our scientist friends who have a lot of time and money to waste have calculated the weight of an electron to be 2.074108*10-29 oz. This is, unsurprisingly, extremely small, but relevant. We know there's forty thousand electrons in a 1 that otherwise wouldn't be there, so we can conclude that a 1 weighs 8.296432*10-25 oz. So, great, that's a 1. But how many bits are in your hundred gigs of questionably-legal-porn? Well, a gigabyte is basically 1,073,741,824 bytes. A byte is also divisible in that is is the manifestation of 8 bits. So, we can multiply the number of bits in a byte with the number of bytes in a gigabyte and... That's 8,589,934,592 bits in a gigabyte. But it's not just ONE gigabyte... No, you're too sick and tasteless for just ONE. You have one HUNDRED gigabytes of porn, which means you have 8,589,934,592,000 bits manifesting porn. So we know that a 1 weighs 8.296432*10-25 oz but remember that bits compose of not just 1s but 0s as well. Typically this is pretty much half and half, and on this scale it's okay to just assume 50% 0s and 50% 1s, so if half of your porno-bits are 1s then that's 4,294,967,296,000 1s. The 0s we can just ignore, as without the 1s it'd be empty disk space. Now let's see how much these 1s weigh! A single 1 weighs 8.296432*10-25 oz, so by multiplying that by the number of 1s in your whackass porn, 4,294,967,296,000, we'll get the weight in ounces of your 100 gigabytes! After punching that into my stock windows calculator, we find your dirty filez weigh 3.563290*10-12 oz! This is basically 3 million millionths of an ounce. So fricking small nobody should even care. Not even me. But we do care, because now we want to know what our magic internet money weighs in at! Cheesy

First we have to define what a bitcoin 'is.' Sure, your private key is what lets you SPEND your bitcoins but the number of BTC available for spending on any given private key is not always exactly 1. If a bitcoin isn't an address, it is what it looks like. What goes INTO the address. Below is a transaction I pulled randomly from a recent block.

Now, this is a full transaction. Not only is it a bitcoin, it's the transporter OF a bitcoin. That which makes the bitcoin move from point A to point B is spending previous outputs and creating new ones. The output of the transaction is the coin, without question or doubt. Let's have a look at the transaction in a more sophisticated manner (get your wine glass!) Cool

      "scriptSig":"3045022100e3a8a88d9354c894b69865cf872b699e3ce5a167c5610f7531e0e1bbcd56370002207810698af68911296b65c96aa619f5f0d82a413081bc45ef4567972f6535c59401 026e1c90bc590d4384c34821a34e7fad44d4e562b4fd106621f5f8d57b331107ba"
      "scriptSig":"30450221009ea9d8c150d9ec1b7e1dc248d47cae148cf481cdfc43c1209dfb5311639296ad022019233456cf51fca1a0267f409ee85f33162b5397198cbd9169cb84484953ecb101 0317e76906da1b7994598c18a373e1e66ee084d060a5608fc50989d664d768ff46"
      "scriptPubKey":"OP_DUP OP_HASH160 03df0ccc7df89082fba7ea25313398b851b058bc OP_EQUALVERIFY OP_CHECKSIG"

Sure, this is the entire transaction. It's a file, 340 bytes. But we want the output. Conveniently, it is as codey and sophisticated as the transaction itself. It's right there, at the bottom of the transaction. That section labeled “out.” In txt format, the transaction as a whole appears to be 1,096 bytes. The output solely returned as 147 bytes. When expressed as a ratio to its 340 byte form on the blockchain, we will blatantly assume 46 bytes. That would be 368 bits to make our bitcoin. We know from earlier to assume that half of the bits are 1s. This is a bit riskier on such a tiny scale; but since I'm too lazy to measure it myself it's what we're going to do. 184 1s in this output. We know from earlier the weight of a 1 is typically 8.296432*10-25 oz, so we can derive that the output “weighs” 1.526543-22 oz on your computer. But that's your computer. How many other computers do these bits have to be represented on in order for there to be consensus that the bitcoin represented by them is there? Every node on the network has 1.526543-22 oz dedicated to your bitcoin. This is a bit funky; Bitcoin is affected by gravity, but its effect is on every computer in the network. And as more computers join the network, the combined effect this coin has on the weight of the computers will grow. Someday there will be millions of nodes and they'll all remember your coin and in doing so they will weigh a little more because of it. Although the “weight” of a bitcoin is as incalculable as any physical aspect of it, we know it will have a lasting (although pathetic) effect for millenia after you yourself won't. RIP, you. Tongue

TL;DR: The weight of a bitcoin is fricking crazy. It doesn't make any sense and it doesn't have to. It's a fucking bitcoin and that's that, but it was cool to think about.

I wouldn't advise you to take this study for granted at some points, but I thought it would be a fun concept to ponder. Comments? Smiley
