L2 solutions now extract significant value from Ethereum without adequately contributing to its security, raising concerns about the network's sustainable future.
L2 Gains and Ethereum's Role
Currently, L2 networks pay minimal fees to Ethereum while generating substantial revenue. For instance, Base generated approximately $2.5 million in fees last month but only paid Ethereum $11,000. Optimism earned $321 for every $1 it contributed to the network.
Economic Discrepancy between L2 and Ethereum
Most rollups do not use ETH as gas, creating their own tokens, further reducing Ethereum’s direct value capture. Although L2s rely on Ethereum’s security, they contribute only a fraction of what they extract, resulting in an economic imbalance.
Creating Economic Balance
Addressing this issue requires L2 involvement in Ethereum's economic security. One proposal is to require L2 sequencers to stake ETH as collateral. Additionally, a portion of all L2 fees should be redirected to Ethereum stakers. MEV produced on rollups must also be redistributed to Ethereum validators.
Ensuring Ethereum's sustainability requires L2 solutions to contribute to its security, maintaining the network's integrity and stability.
