-## Scope
+## Status
+
+There a 3 milestones defined, we are currently on the first one.
+
+### M0: Read and Write integration
 
 The scope of this first milestone is to spin up a local EigenDA dev environment, spin up a local zksync-era dev
 environment and integrate them. Instead of sending 4844 blobs, the zksync-era sends blobs to EigenDA. On L1, mock the
 verification logic, such that blocks continue building. Increase the blob size from 4844 size to 2MiB blob. Deploy the
 integration to Holesky testnet and provide scripts to setup a network using EigenDA as DA provider.
 
+### M1: Secure integration with ZKProver
+
+For this milestone the scope is to replace the mocked L1 verification logic with EigenDA compatible verifier. It should
+integrate EigenDA certificate verification, and use it as the equivalent part for 4844 versioned hash. More importantly
+modify the equivalence proof in Zksync L1 contract such that the proof can be verified correctly with respect to the
+EigenDA commitment, which also lives in BN254 as zksync. Start with 128MiB blob, then 2MiB, up-to 32MiB blobs. Prepare
+documentation and tooling in order to onboard rollups with EigenDA.
+
+### M2: Secure and cost efficient
+
+The scope is to explore approaches to reduce cost. For example, faster proof generation time. Verify EigenDA signature
+inside circuit, this requires L2 having access to L1 state. Integrate EigenDA into ZKporter.
