"description": "Rollup users have access to all the data, as it is posted onchain on the consensus layer. On the execution layer, the rollup relies on blob data commitment (versioned hashes), which are accessible through the BLOBHASH opcode. \nThe rollup smart contracts can use these blob commitments during state transition validation to reference blobs during proof verification, without requiring direct access to the raw blob data.\n "
},
"callout": "Unlike non-enshrined DA bridges, it does not place any honesty\n assumption on an external committee that provides data availability\n attestations to the DA bridge. From the rollup perspective,\n Ethereum's canonical chain cannot contain unavailable data\n commitments as full nodes self-verify the data availability of each\n block, discarding blocks with unavailable data. The rollup state\n validating bridge has access to all the data, as it is posted on chain."

"description": "\n ## Enshrined Bridge\n The DA bridge on Ethereum is enshrined, meaning that blob data is directly accessible on the consensus layer, with data availability guaranteed by the network's inherent consensus rules. \n If a block contains unavailable data, full nodes will reject it, causing the chain to fork away from that block. This ensures data availability without requiring additional trust assumptions. \n In contrast, external DA providers must rely on data availability attestations from the external validator set, introducing an extra layer of trust on the majority of validators.\n "
