Today, Ethereum founder Vitalik Buterin released an analysis of Layer 2s (L2s) and base layer execution sharding in scaling Ethereum, highlighting the key similarities and differences in these approaches.

In his new post, Buterin explored the parallels between L2s and sharding, noting how these approaches similarly aim to handle a large volume of transactions efficiently.

He emphasized that the endgame for both these methods is relying on ZK-SNARKs for computation verification and Data Availability Sampling (DAS) for data verification. Despite these similarities, he went on to explain how there are distinct differences that persist.

Buterin wrapped up by reiterating that while L2s and sharding have their idiosyncracies and are often seen as distinct scaling strategies, they are fundamentally similar in their general technical approaches.

The main difference, he noted, lies in who builds and maintains these components and the level of autonomy they possess. He concluded by emphasizing the need for addressing the coordination challenges of an L2-centric approach to fully realize its potential.

Some people in the Ethereum community still long for the original sharding vision, though as Vitalik's new post demonstrates, Ethereum has taken an approach via L2s that, in effect, is shardingit's just arrived along a different path than was initially planned. While pure sharding has its pros, the flexibility possible with rollups is a big leg up and highlights how Ethereum is now well-suited for development efforts of all stripes.
