The Tezos Data Availability (DA) layer is an important part of the Tezos blockchain. It enables the Tezos network to store and replicate data in a secure and efficient manner. The DA layer is responsible for ensuring that all data stored on the Tezos blockchain is available and accessible to all users. To track the development of the DA layer, you can refer to the GitLab Milestone Tracker and the official Tezos Spotlight blog. Arthur Breitman, the founder of Tezos, recently wrote an article on the Tezos Spotlight blog which explains the importance of the DA layer and how it works. This article is a great resource for anyone who wants to learn more about the DA layer and its role in the Tezos blockchain.
