According to Odaily, Optimism has announced that the Alt-DA mode is now available in the OP Stack test version. This new development allows any DA layer to build its own DA server for integration into the OP Stack. Currently, three decentralized DA layers have been launched, namely Celestia, EigenDA, and Avail. This move is seen as a significant step towards enhancing the functionality and versatility of the OP Stack platform. The integration of these decentralized DA layers into the OP Stack test version is expected to provide users with more options and flexibility in their operations. Further details about the implementation and potential impact of this development are yet to be released.
