+## Project Overview :page_facing_up:
+
+
+This Project based in [ZEXE](https://github.com/AleoHQ/zexe/tree/master) and [ZEXE paper](https://eprint.iacr.org/2018/962).
+In order to  implement ideal_ledger,plain_dpc,delegable_dpc Pallet. 
+
+
+### Overview
+
+This project will implement ideal_ledger,plain_dpc,delegable_dpc pallet (The following content is taken from  ZEXE paper):
+
+1. ideal_ledger pallet
+    In ZEXE's prototype.It is simply an ideal ledger, an append-only log of valid transactions that is stored in memory.
+    It maintain a Merkle tree.
+2. plain_dpc  pallet
+    It is decentralized private computation (DPC) schemes, a cryptographic primitive in which parties with access to an ideal append-only ledger execute computations offline and subsequently post privacy-preserving, publicly-verifiable transactions that attest to the correctness of these offline executions. 
+3. delegable_dpc  pallet
+	It is a DPC scheme in which a user can delegate to an untrusted worker the expensive computations associated with producing a transaction. The security goal is that the worker should not be able to produce valid transactions that have not been authorized by the user.
+4. dpc_cli
+    It is offline proof computation cli tool.It implements `execute` function part of plain_dpc and delegable_dpc.

+
+| Number | Deliverable | Specification |
+| -----: | ----------- | ------------- |
+| **0a.** | License | Apache 2.0 and MIT |
+| **0b.** | Documentation | We will provide both **inline documentation** of the code and a basic **tutorial** that explains how a user can (for example) spin up one of our Substrate nodes and send test transactions, which will show how the new functionality works. |
+| **0c.** | Testing and Testing Guide | Core functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests. |
+| 1. | ideal_ledger pallet| We will implement main functions:`push transaction`,`prove transaction`,`verify transaction` and so on. |
