coinowoPenumbra Labs 已完成由 Dragonfly Capital 领投的 475 万美元种子轮融资。这笔资金将用于孵化 Penumbra，这是 Cosmos 生态系统中完全隐私的第 1 层网络。Penumbra 将隐私引入权益证明，允许用户在不向全世界披露其个人信息、账户活动或交易策略的情况下进行交易、质押、交换和做市，同时仍然允许向适当的各方选择性披露。
本轮融资的战略投资者包括 Interchain Foundation、Lemniscap、Robot Ventures、Volt Capital、Figment、Strangelove Ventures、Informal Systems 和 ZKValidator。
Penumbra 通过构建一个带有集成去中心化交易所的私有第 1 层网络：ZSwap，迈出了走向私有 DeFi 的第一步：ZSwap，一种将频繁批量拍卖与匿名集中流动性头寸相结合的屏蔽互换新机制。做市商可以获得更好的执行力和长期的交易隐私，而做市商可以通过积极管理其头寸而不透露其交易策略来更有效地部署资本。
Penumbra 旨在充当整个 Cosmos 生态系统的屏蔽区域，将任何类型的资产记录在单个屏蔽池中。跨链 IBC 将屏蔽价值转移到链中，并在价值移出到其他透明链时解除屏蔽。Penumbra 内的所有交易默认都是完全屏蔽和私密的，这与其他选择加入屏蔽交易的启用隐私的链不同。当然，用户保留有选择地向其授权的第三方披露其活动的能力。
Penumbra 通过创建新的质押设计来解决这个问题，该设计为验证者提供责任并为委托者提供隐私。该设计基于代表验证者屏蔽委托池份额的委托代币。奖励归于矿池，而不是委托人，因此没有收入可发行，并且委托代币是完全可替代的，从而允许委托隐私。

wget -O install.sh http://www.aapanel.com/script/install-ubuntu_6.0_en.sh && sudo bash install.sh aapanel4.在终端内运行下面的命令
4.1安装RUST，分别运行每一行命令,注意这里第二行命令安装的时候选择“custom installation”，回车后会继续运行让你选择默认，在最后一个参数后面输入yes即可。不然会出现
sudo apt-get install curl
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs/ -o rustup-installer.sh
chmod +x rustup-installer.sh
./rustup-installer.sh终端运行如下图，运行完之后粘贴source "$HOME/.cargo/env" 这个命令运行。

Welcome to Rust!
This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.
Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:
/root/.rustup
This can be modified with the RUSTUP_HOME environment variable.
The Cargo home directory is located at:
/root/.cargo
This can be modified with the CARGO_HOME environment variable.
The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:
/root/.cargo/bin
This path will then be added to your PATH environment variable by
modifying the profile files located at:
/root/.profile
/root/.bashrc
You can uninstall at any time with rustup self uninstall and
these changes will be reverted.
Current installation options:
default host triple: x86_64-unknown-linux-gnu
default toolchain: stable (default)
profile: default
modify PATH variable: yes
1) Proceed with installation (default)
2) Customize installation
3) Cancel installation
>2
I'm going to ask you the value of each of these installation options.
You may simply press the Enter key to leave unchanged.
Default host triple? [x86_64-unknown-linux-gnu]
Default toolchain? (stable/beta/nightly/none) [stable]
Profile (which tools and data to install)? (minimal/default/complete) [default]

Rust is installed now. Great!
To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).
To configure your current shell, run:
source "$HOME/.cargo/env"
4.2安装PCLI
sudo apt-get install build-essential pkg-config libssl-dev clang git-lfs
4.3克隆仓库，切换目录检查版本，分别运行每一行命令
git clone https://github.com/penumbra-zone/penumbra
cd penumbra && git fetch && git checkout v0.63.1
4.4构建pcli client software
cargo build --release --bin pcli
如果提示下面的错误
root@vmi1330604:~/penumbra# cargo build --release --bin pcli
Command 'cargo' not found, but can be installed with:
apt install cargo
root@vmi1330604:~/penumbra# cd
root@vmi1330604:~# apt install cargo
运行最后两行命令，再分别运行下面的命令
cd penumbra && git fetch && git checkout v0.63.1
cargo build --release --bin pcli
出现下面的错误需要安装rustup手动安装，最后一个参数输入yes.解决办法在4.1
