Base: How Coinbase Accidentally Built the World's Second-Largest Ethereum L2 While Retaining Engineers

·

Introduction

Last week, I asked readers whether they would invest in Ethereum ETFs. Surprisingly, 93% of voters preferred holding ETH directly over buying ETFs. This sets the stage for today's discussion on Base, Coinbase's unexpectedly successful Ethereum Layer 2 solution that emerged from a talent-retention challenge.

The Rise of Base Chain

Base has rapidly ascended to become the second-largest Ethereum L2 by active addresses, trailing only Arbitrum. Key milestones:

Ethereum founder Vitalik Buterin emphasizes that cultural fit drives L2 adoption. Base cultivates this through initiatives like:

Evolution of the Vision

Business Impact and Future Outlook

Financial Significance

Strategic Positioning

Analysts compare Coinbase's trajectory to Amazon's:

  2. Expanded to infrastructure (AWS/Base)
  3. Now powering next-gen applications
