Discovery (Orbit EigenDA) Testnet
Last updated
Last updated
Discovery is an Arbitrum Orbit public testnet that uses EigenDA as its data availability layer.
With Discovery, L2 transaction data are written to EigenDA. The resulting EigenDA blob key is then written to Ethereum calldata. By doing so, the cost of the calldata becomes relatively negligible, even when the actual blob data is megabytes in size. The sequencer will then be able to retrieve the blob keys from the calldata and then retrieve the blob from EigenDA.
To learn more about Orbit EigenDA, please refer to EigenLayer's Orbit Integration article.
