Bitcoin’s long gestation and early opposition indicates it is an example of the ‘Worse is Better’ paradigm in which an best gpu for bitcoin mining 2012 election complex design with few attractive theoretical properties compared to purer competitors nevertheless successfully takes over a niche, survives, and becomes gradually refined. But the interesting thing is, Satoshi could be anybody. Bitcoin involves no major intellectual breakthroughs, so Satoshi need have no credentials in cryptography or be anything but a self-taught programmer! I can’t tell you why it took as long for weblogs to happen as it did, except to say it had absolutely nothing to do with technology.
Every single piece of it was right there. The interesting thing is that all the pieces were in place for at least 8 years before Satoshi’s publication, which was followed more than half a year later4 by the first public5 prototype. This lack of novelty is part of the appeal – the fewer new parts of a cryptosystem, the less danger10. All that was lacking was a Satoshi to start a Bitcoin. Delay But with the benefit of this hindsight, one can wonder – why this delay? 12, if it is very far from the cutting-edge of cryptography13, then there’s no reason it would not be seriously tried. Is the problem one of resources?
A block header with no transactions would be about 80 bytes. With computer systems typically selling with 2GB of RAM as of 2008, and Moore’s Law predicting current growth of 1. 2GB per year, storage should not be a problem even if the block headers must be kept in memory. That’s fine to say in 2008, after many doublings. Would memory be a problem in the 1990s? Bitcoin was begun in the early 1990s, the changeover would simply have occurred sooner.
