The Promise of the Cancun Upgrade:
The Ethereum community eagerly anticipates the Cancun upgrade, expected to revolutionize Layer 2 (L2) gas fees. With the deployment of EIP4844, Ethereum introduces three new Blob spaces designed to store L2 transactions and state data, potentially decreasing average gas fees by a factor of ten or more.
Impact on Gas Fees:
This significant expansion in block space supply could reduce gas prices drastically if demand remains constant. However, the dynamics of competition among Rollup L2s for Blob space complicate these projections, suggesting a less dramatic decrease in fees than initially anticipated.
The Zero-Sum Game of Blob Space:
The competition for Blob space among Rollup L2s is likened to a zero-sum game, where the leading platforms may leverage this new resource to dominate the market, potentially at the expense of smaller competitors. Such strategies could mitigate the intended effects of the Cancun upgrade on reducing gas fees.
The Reality of Gas Fee Reduction:
While the Cancun upgrade aims to lower L2 gas fees significantly, the actual decrease may fall short of market expectations. The interplay of competition for Blob space and the adjustment strategies of Rollup L2s will be crucial factors in determining the real impact on gas fees.
