0/ The 2014 Ethereum Whitepaper set the foundation for what Ethereum is today. 

The paper addressed challenges blockchains would likely face. 

Scalability was one of them.

1/ The paper did not explicitly provide a solution to the scalability challenge but instead left it open. 

Ethereum was able to start making an impact even without every challenge solved.

2/ In 2017, Vitalik Buterin & Joseph Poon proposed Plasma, a framework for off-chain scaling secured by Ethereum.

This led to years of experimentation and evolution that resulted in the foundation of Ethereum’s scaling strategy: Layer 2 rollups.
