When was the birth of Bitcoin?

[jabo38]

Wikipedia says it was on January 3, 2009 https://en.wikipedia.org/wiki/Bitcoin

Blockchain says January 9, 2009 https://blockchain.info/block/00000000839a8e6886ab5951d76f411475428afc90947ee320161bbf18eb6048

Also, was Bitcoin the first blockchain?

January 3 was the announcement and code release.

From Wikipedia's source:

That’s what he did on the evening of January 3, 2009, when he pressed a button on his keyboard and created a new currency called bitcoin. It was all bit and no coin. There was no paper, copper, or silver—just thirty-one thousand lines of code and an announcement on the Internet.

You have definitely been around longer to me so I am perfectly willing to accept that narrative, but then I wonder why Blockchain has a different date stamp. 

I am thinking that maybe the first chain died after a week and had to be started over?  Is that a possibility? 

We all know well that the original code was meant to be sloppy.

Oh, sorry, Wikipedia article is correct, genesis block was created on January 3rd.

You got the wrong block, here's the first one:

what does that mean.  why so many sig figs.

i thought bytes only went 8 deep

[Tstar]

on 3th January 2009 its code was finalized and first gensis block was generated
and on 9th January 2009 it was released to public

[Remember remember the 5th of November]

Well, depends on what OP means, Bitcoin was in development many years before it was announced. And the genesis block(number 0 in bc.i https://blockchain.info/block/000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f) contains the message "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" so Jan 3, 2009.

That might be the day it was released to the public, but I wonder when it was conceived and how long it actually took him to develop bitcoin from his initial idea. It seems to me like it would have taken quite some time to figure out.

Well, bitcoin.org was registered in August of 2008 so it's safe to say Bitcoin has already been conceived, at least in SN mind. There are interesting bits and pieces out there but very little from the founder himself - he was strictly business and shared very little of his life struggle and personal journey thing with the public.

thanks for sharing. from just a few cents to over 1000$ just wow.

When Satoshi was born, Bitcoin was born

1 KB = 1024 bytes
0.2099609375 KB = 215 bytes (the block is 215 bytes in size, and the number of bits in a byte don't come into play here)
Technically correct, but a very strange way to write it. If you ask me, they should have just listed it in bytes.

Also, Satoshi posted his paper on 2008-11-01 (side note: only reply shown there is basically the "blockchain size"/scalability/bandwidth requirement issue that has been asked so many times since). It's interesting to note that the whitepaper is so generic that it could define not just Bitcoin, but Litecoin and countless other variants (IOW he hadn't necessarily already settled on SHA-256, 10 minute target time, ECDSA, etc). Then he released the first version of Bitcoin in January 2009.
I'd guess that he started working on Bitcoin in earnest by June 2008, likely earlier.

Also, was Bitcoin the first blockchain?

AFAIK, yes.

1 KB = 1024 bytes

Just no.

'K' denotes 1000, or 10^3.

Always has, always will. Every standards organization on the planet that has any bearing on the matter is unanimous on this point. The fact that 2^10 is very near the value 10^3 is irrelevant. It has been misused for convenience, but has never been correct.

If you want a quick and easy indicator for 1024 or 2^10, you can use 'Ki'.

Stop misusing 'K' before you kill again.

1 KB = 1024 bytes is obviously the definition used by Blockchain.info. It's also the definition used by memory manufacturers, Windows Explorer, and most non-pedantic people (whether "techies" or not).
If you want to look at the most "official" standards instead of common usage, then this is right: 1000 bytes = 1 kB (kilobyte), and 1024 bytes = 1 KiB (kibibyte).
As long as we're being pedantic, the metric symbol for kilo (1000) is "k", not "K", so you too are wrong.

See also: https://en.wikipedia.org/wiki/Kilobyte, which says the KB is usually used for 1024 bytes.

From your quoted wikipedia kilobyte article:

"In the International System of Quantities, the kilobyte (symbol kB) is 1000 bytes, while the kibibyte (symbol KiB) is 1024 bytes. "

From your memory manufacturers link:

"Quote from JEDEC Standard 100B.01, page 8:
 The definitions of kilo, giga, and mega based on powers of two are included only to reflect common usage. IEEE/ASTM SI 10-1997 states "This practice frequently leads to confusion and is deprecated.""

Misusing 'K' for 'Ki' has killed. It it a stupid pointless anachronism that must stop.

I think white paper was published on 31th October 2008. Worlds day of banking.

This might not be birthday. But maybe day when Bitcoin was made. It was delivered few months latter.

Okay, so I got a lot of clarity. 

The first block (block #0) was on Jan 3th, but then the second block (block #1) wasn't until Jan 9th. 

So can I assume it took 6 days to form the first block after genesis?  Or maybe there was a problem and so that was the delay?

It looks like after block #1 things were moving okay, so does anybody know the delay of 6 days? 

Did he turn his computer off or something and since he was the only miner then nobody found a block?

Do not quote me on this but I've read somewhere (was it Forbes article? I do not remember) SN had very slow, old PC at that time which was getting hot and needed to be turned off every couple hours. Or may be I'm confusing it with Hall's Finney story where Hall had to turnr off his mining after a few weeks on account of the overheating computer. He actually showed reporter his first wallet with first SN transaction and mining rewards. His wallet has showed exactly 2 x 50 block rewards, or 100 BTC per day during first days of mining which means somebody else, or at least other miners where getting the rest: 142 blocks or roughly 7100 bitcoins a day. Here goes theory of bad SN computer, but If SN and HF had weak and unstable computers somebody else was raping the network rewards with much more powerful computers. Hmm :-) Welcome to another dark rabbit hole Ladies & Gentleman.
