According to the Ethereum Foundation's definition, Ethereum's Layer 2 = Rollup. According to Vitalik's recent new perspective, if other EVM chains use non-Ethereum as Data Availability (DA), then it is Ethereum Validium (moving the data availability layer of the blockchain off-chain, using valid proofs to ensure the integrity of off-chain transactions). Although there is still some controversy over the precise definition of Layer 2 due to the issues with DA, Ethereum's upgrade path remains centered around Rollup, with DA playing a crucial role in storing or uploading Rollup transaction data in Ethereum upgrades. |
