L2s are choosing single DA layers to outsource data availability, despite DA layers are a novel tech and can implement lock-in strategies.
panDA is an abstraction layer for DAs which was showcased at ETHGlobal London in early 2024.
L2s can leverage panDA or similar abstraction layers to achieve redundancy in DA commitments (thus abstracting out DA layers), and anyone can verify the DA inclusion proofs from any chain thanks to SafeJunction.
