+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+
+WeDPR是一系列**即时可用场景式**隐私保护高效解决方案套件和服务（参见[WeDPR白皮书](https://mp.weixin.qq.com/s?__biz=MzU0MDY4MDMzOA==&mid=2247483910&idx=1&sn=7b647dec9f046f1e6f94d103897f7efb&scene=19#wechat_redirect)），由微众银行区块链团队自主研发。方案致力于解决业务数字化中隐私不“隐”、共享协作不可控等隐私保护风险痛点，消除隐私主体的隐私顾虑和业务创新的合规壁垒，助力基于隐私数据的核心价值互联和新兴商业探索，营造公平、对等、共赢的多方数据协作环境，达成数据价值跨主体融合和数据治理的可控平衡。
+
+WeDPR具备以下特色和优势：
+
+- **场景式解决方案**：已基于隐匿支付、匿名投票、匿名竞拍、匿名摇号和选择性认证披露等应用场景，提炼出公开可验证密文账本、多方密文决策、多方密文排名、多方密文计算、多方安全随机数生成、选择性密文披露等高效技术方案框架模板，5分钟一键构建示例应用。
+- **即时可用**：高性能、高易用、跨平台跨语言实现、不依赖中心化可信服务、不依赖可信硬件、支持国密算法标准、隐私效果公开可验证。
+- **透明可控**：隐私控制回归属主，杜绝数据未授权使用，在『数据可用而不可见』的基础上，进一步实现数据使用全程可监管、可追溯、可验证。
+
+WeDPR全面拥抱开放，将陆续开源一系列核心算法组件，进一步提升系统安全性的透明度，提供更透明、更可信的隐私保护效果。WeDPR-Lab就是这一系列开源的**核心算法组件**的集合。
+
+首组开源的核心算法组件将围绕**公开可验证密文账本**（Verifiable Confidential Ledger, VCL）解决方案进行，在数字化资产流通场景（如支付、清算）、涉及多方之间共享账本信息的场景（如供应链金融、跨境金融服务）等均可广泛应用。
+
+本次开源（v1.0.0版本）包含的主要内容如下：
+
+- 公开可验证密文账本的一个交互式样例，实现密文金额发行、密文金额四则运算关系验证、密文金额范围验证等功能；
+- Rust SDK，封装底层算法，提供易用、易扩展、跨语言的编程接口；
+- 三类零知识证明算法的高效稳定实现，包括密文加和关系证明、密文乘积关系证明、密文范围证明；
+- 其他基础工具代码。
+
+我们期望能够通过代码开源的方式：
+
+- 有效降低使用隐私保护算法组件的技术门槛；
+- 减少业务系统集成隐私保护特性的开发成本；
+- 助力全行业伙伴安全、合规地开展数据业务。
+
+欢迎社区伙伴参与WeDPR-Lab的共建，一起为可信开放数字新生态的构建打造坚实、可靠的技术底座。
+
+## 安装
+
+### 安装Rust环境
+
+1. 安装nightly版本的Rust开发环境，可参考[示例安装指引](https://wiki.jikexueyuan.com/project/rust/nightly-rust.html)。
+2. 若有疑问，可进一步参考[Rust官方文档](https://www.rust-lang.org/tools/install)。
+
+### 下载WeDPR-Lab源代码
+
+使用git命令行工具，执行如下命令。
+
+```bash
+git clone https://github.com/WeBankBlockchain/WeDPR-Lab-Core.git
+```
+
+## 运行Demo
+
+### 运行公开可验证密文账本Demo
+
+```bash
+cd WeDPR-Lab-Core/solution/verifiable_confidential_ledger
+cargo run
+```
+
+在VCL解决方案子目录（即`verifiable_confidential_ledger`目录）中，运行cargo run之后，按照demo指引，选择演示的语言，按步骤输入即可进行体验。
+
+## 接口文档
+
+### 生成并查看Rust SDK接口文档
+
+在本项目的根目录（即`WeDPR-Lab-Core`目录）中，运行如下命令。
+
+```bash
+cargo doc
+```
+
+以上命令将根据代码中的注释，在`target/doc`子目录中，生成的SDK接口文档。
+
+进入`target/doc`文档目录后，会看到所有SDK相关的包名（包含WeDPR-Lab和其他依赖包），进入以下任意一个包名的目录，用网页浏览器打开其中的`index.html`文件，便可查看WeDPR-Lab相关的接口说明。
