The Role of L2s

In the latest podcast, experts delve into the dynamics between alternative layer 1 blockchains and Ethereum, assessing whether these ecosystems coexist symbiotically or compete parasitically.

Competition Between Layer 1s and Ethereum

  • “Those L1s are definitely parasitic to Ethereum because they're actively not in the Ethereum ecosystem.”
  • “Every kind of user that's on Tron is a user that Ethereum lost or didn't gain.”
  • The emergence of alternative L1s like Tron and Binance Smart Chain (BSC) presents direct competition to Ethereum, often drawing away users and developers.
  • These L1s operate on separate ecosystems with their own native tokens (TRX for Tron), reducing interoperability with Ethereum.
  • By not contributing to Ethereum’s ecosystem through collaboration or shared revenue models, they position themselves as rivals rather than partners.
  • The user base of these L1s directly impacts Ethereum, potentially slowing its growth and adoption.

Economic Activity and Ecosystem Impact

  • “They’re not doing anything really except you could make the argument the most that they're doing is increasing the EVM network effect.”
  • Alternative L1s engage in economic activities that, while extensive, offer limited benefits to Ethereum.
  • The primary economic contribution is attracting Solidity developers, which could indirectly benefit Ethereum by increasing the overall EVM (Ethereum Virtual Machine) network effect.
  • However, without substantial collaboration, these activities do not translate into significant value for Ethereum’s ecosystem.
  • The lack of direct financial or social investments into Ethereum means the economic activities remain largely self-contained.

Developer and Network Effects

  • “Increasing the EVM network effect brings more Solidity developers in who can then develop on the L2s or on Ethereum L1.”
  • The presence of multiple L1s leveraging the EVM standard has nuanced effects on the broader blockchain development landscape.
  • By standardizing on Solidity, these L1s make it easier for developers to create across multiple platforms, fostering a broader base of blockchain innovation.
  • This standardization can lead to more robust toolsets and resources that benefit the entire Ethereum ecosystem, albeit indirectly.
  • However, the competition for developer attention and resources can dilute efforts that might otherwise have been concentrated on enhancing Ethereum’s capabilities.

Isolation of Ecosystems

  • “They’re actively like not in the Ethereum ecosystem, not trying to help the Ethereum ecosystem...”
  • The intentional separation of these L1s from Ethereum limits potential collaborative growth and shared advancements.
  • Separate ecosystems mean that technological innovations may not be shared or integrated, reducing the overall progress of the blockchain space.
  • Lack of interoperability efforts stifles the creation of a unified, more efficient blockchain infrastructure.
  • This isolation exacerbates market fragmentation, making it harder for any single ecosystem to dominate comprehensively.

Key Takeaways:

  • Layer 1 Competition: Alternative L1s like Tron and BSC pose significant competitive threats to Ethereum by siphoning users and developers without contributing to its ecosystem.
  • Limited Symbiotic Benefits: While these L1s may attract Solidity developers, the overall symbiotic relationship is minimal, with most economic activities not enhancing Ethereum’s value.
  • Market Fragmentation Risks: The isolation of these ecosystems leads to fragmentation, potentially hindering unified advancements and reducing the collective strength of the blockchain industry.
