🔥 ON THIS DAY: Nov 2, 2008, Bitcoin got its first public reply, two days after Satoshi shared the whitepaper. "We very, very much need such a system… it does not seem to scale to the required size." This was the first time anyone publicly pushed back on Bitcoin, and it was about scaling. The same debate later drove the 2017 block-size wars, Lightning and today's layer 2s.
