Ethereum’s Multichain Shift and the Role of Layer 2 Data Availability
Summary
Drawing on observations and panel discussions at ETHDenver 2024, this report describes Ethereum’s evolving relationship with Layer 2 rollups and competing blockchain networks. Rollups move transaction execution away from Ethereum, and some teams are exploring external data availability systems to lower costs or differentiate their networks. The report presents developers’ views that the Dencun upgrade and EIP-4844 could reduce costs, while alternative providers such as Celestia may still appeal to projects seeking additional flexibility.
The discussion frames this shift as both a competitive challenge and a possible multichain direction for Ethereum. If rollups settle data elsewhere, Ethereum could lose activity and influence; the report argues that improving its data capacity could help it remain a central security and settlement layer for rollups. Its evidence consists primarily of conference presentations, interviews, and the author’s interpretation of ecosystem trends, not measured adoption or performance comparisons. The conclusion that Ethereum should become a leading data availability layer is a strategic view, and future outcomes depend on upgrades, costs, and rollup choices.
Key ideas
- Layer 2 rollups shift transaction execution away from Ethereum while continuing to depend on external infrastructure choices.
- Some rollup teams are testing data availability providers beyond Ethereum to reduce costs or distinguish their networks.
- Dencun and EIP-4844 were discussed as ways Ethereum could improve data capacity and reduce costs for rollups.
- External data availability may make rollups more flexible while weakening their reliance on Ethereum for settlement.
- The report’s conclusions reflect conference discussions and strategic interpretation rather than comparative performance data.
