size is 0.2099609375 KB
what does that mean. why so many sig figs.
i thought bytes only went 8 deep
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.
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.
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.
