On November 2, 2008, $BTC received its first public reply, just two days after Satoshi published the whitepaper.

James A. Donald’s concern?

“We very, very much need such a system… it does not seem to scale to the required size.”

Think about that. Bitcoin’s scalability was questioned before the network even launched.

Nearly two decades later, the same challenge has shaped the block-size wars, SegWit, the Lightning Network and today’s Layer 2 development.

Bitcoin’s first major technical debate was about scaling.

And it never really went away.
