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.

The universal platform for crypto, blockchain apps, stablecoins & decentralized tech. An account about the Ethereum ecosystem maintained by @ethereumfndn.

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.

4/ As Ethereum looks ahead to the next 10+ years, challenges like scalability serve as a reminder: the unknown can be a driver of innovation.

3/ Today, there are many rollups that are scaling the ecosystem without compromising security or decentralization.
