The direct competition for DAL is Celestia, which is a data storage protocol that is enshrined within the L1 protocol. However, Tezos is taking a different approach and is building the DA as a L2 into its L2 protocol. This puts the control of the Data Availability Layer back in the hands of the same players that are in control of Layer 1, and doesn't require a new token economy. Tezos' approach is more advantageous than Celestia's, as it provides a more unified system with fewer moving parts. Additionally, it eliminates the need for a separate token, which can be a major benefit for many users.
