Charles Hoskinson's recent AMA comments have sparked heated discussions, directly pointing out the flaws in Ethereum's economic model and Layer 2 solutions, even using sharp terms like "parasite". As the leaders of two major public chains, this remote confrontation actually reveals fundamental divergences in blockchain development paths.

Is Layer 2 really a "parasite"?

Hoskinson's criticism is not without reason:

- Cost contradiction: Layer 2 reduces gas fees, but the mainnet staking and DA layer still rely on Ethereum, fundamentally not solving the scalability cost issue.

- Ecological fragmentation: The liquidity between different L2s is fragmented, complicating user experience (cross-chain bridge risks, overlapping fees, etc.).

But Ethereum supporters would argue:

- Modular experimentation: Solutions like Rollup and Validium are inevitable attempts at the "division of labor" in blockchain, similar to how the internet evolved from standalone to cloud computing.

- Real-world adoption: The daily active users and TVL of L2s like OP Mainnet and Arbitrum prove that the market votes with its feet, while Cardano's Hydra and other solutions have yet to be validated at scale.

Has Ethereum really lost its innovation?

Despite facing challenges, Ethereum still leads in key areas:

- Developer ecosystem: The Solidity smart contract standard and large DApp library form a moat, while Cardano's Haskell remains a high barrier to entry.

- Orthodoxy upgrade: The Dencun upgrade has drastically reduced L2 costs with blob transactions, and the Pectra upgrade continues to optimize the staking experience.

- Financial depth: The on-chain infrastructure maturity of DeFi, NFTs, and RWAs far exceeds that of other ecosystems.

Who do you hold long-term optimism for? It depends on your "belief".

- If you believe in "robustness above all": Cardano's academic route and PoS design may be more appealing to long-termists, but it requires enduring slow ecological progress.

- If you embrace "evolution in chaos": Ethereum's rapid iteration and L2 competition, while not perfect, are currently the most active innovation testing grounds.

The author's bold statement: Hoskinson's criticism is like saying "your car burns fuel, while my horse-drawn carriage is more environmentally friendly", but users clearly chose the faster road option. However, the public chain war is far from over, and the final winner may need to combine rigorous systematization (Cardano) with wild growth potential (Ethereum).

How do you choose? Is it betting on Ethereum's L2 network effects or Cardano's "slow and steady" approach? See you in the comments! 👇
