+The major deliverable of this milestone is Manta substrate pallet that support the basic DAP scheme:
+1. Mint private coin, a user could mint a DOT/KUSAMA coin to a private coin in Manta
+2. Transfer private coin, a Manta user could transfer a private coin to another user Manta user by providing an address and a zero-knowledge proof of the private coin that she owns
+
+The Manta substrate pallets includes the ledger state implementation, the transaction validation logic which involves the validation of zero-knowledge proofs. Note that this milestone will only support converting DOT/KUSAMA to private coins.

+There are two major new deliverable in Milestone 2:
+1. Extend the Manta pallet to support parachain assets. We are still figuring out what is the best way of supporting that. This essentially requires a cross-chain communication mechanism such as XCM or XCMP (which hasn't been put into Rococo yet). We are also actively talking to Polkadot eco-systems members such as Acala and Equilibrium to discuss what is the best standard interface for mining parachain asset to private coins.
+2. A client prototype, which could:
+   * Sign and initiate Mint transactions
+   * Generate zero-knowldge proofs and send transfer transaction of private coins
+   We plan to benchmark and optimize the efficiency of zero-knowledge proof generation
