 # Running the DAL as a Weeklynet baker, in 5 steps
 
-Tezos' Data-Availability Layer (DAL for short), which we presented [in a previous article](https://research-development.nomadic-labs.com/data-availability-layer-tezos.html), is a key component of our scalability roadmap for Tezos. In a nutshell, the DAL is about increasing the bandwidth available for Tezos smart rollups thanks to a new parallel P2P network on which rollup could connect to fetch inputs but without compromising their security and in particular the possibility for any participant to detect fraud attempts from rollup operators and refute them in the Tezos protocol.
+Tezos' [Data-Availability Layer](https://tezos.gitlab.io/shell/dal.html) (DAL for short), is a key component for the scalability of Tezos. In a nutshell, the DAL is about increasing the data bandwidth available for Tezos smart rollups thanks to a new parallel P2P network on which rollup could connect to fetch inputs but without compromising their security and in particular the possibility for any participant to detect fraud attempts from rollup operators and refute them in the Tezos protocol.
 
 In order for the DAL to be as secured as the Tezos Layer 1 itself, bakers would play a very important role in it. Currently, bakers on the L1 network are not only responsible for producing blocks but also for attesting that blocks are published on the L1 network; they are rewarded for this through protocol incentives and they also monitor the behaviour of other bakers to denounce cheating attempts. Similarly, the role of bakers for the DAL would be to attest the publication of data on the DAL P2P network, they would be rewarded for this through protocol incentives, and denounce cheating attempts from other bakers.
