匿名币 Grin 节点搭建与 Grin Wallet 创建和转账

Posted by Calvin on 2019-07-17

1、Grin 节点搭建与 Grin Wallet 创建

1.1 下载 Grin Node 包

在 Grin 的 Github 页面选择对应的安装包进行安装，这里以 Ubuntu 18.04.2 LTS 系统为例

下载 Grin releases 包

wget https://github.com/mimblewimble/grin/releases/download/v2.0.0/grin-v2.0.0-linux-amd64.tar.gz

解压到当前目录

tar -zxvf grin-v2.0.0-linux-amd64.tar.gz

设置环境变量全局路径

mkdir -p ~/grin
tar xzf grin-v1.0.0-479973573-linux-amd64.tgz -C ~/grin
echo export 'PATH=~/grin:$PATH' >> ~/.bashrc
source ~/.bashrc

设置好环境变量路径后则可在任意目录下执行 Grin 命令

连接 Grin 节点

grin

连接 Grin floonet 节点

grin --floonet

如果未设置环境变量全局路径，则需要在 Grin 目录下执行以上的命令

连接主网节点

./grin

连接 floonet 测试网节点

./grin --floonet

第一次执行连接命令后，需要等待节点数据下载与同步操作，同步完成后如下图：

1.2 Grin Wallet 安装与创建

保持 Grin 节点开启，重开终端窗口进行 Wallet 创建，因为 Wallet 创建成功后需要连接到刚才创建的节点中，所以务必保持节点开启状态。

在 Grin-Wallet 的 Github 页面选择对应的 Wallet 安装包进行安装，这里以 Ubuntu 18.04.2 LTS 系统为例

下载 Grin-Wallet releases 包

wget https://github.com/mimblewimble/grin-wallet/releases/download/v2.0.0/grin-wallet-v2.0.0-linux-amd64.tar.gz

解压到当前目录

tar -zxvf grin-wallet-v2.0.0-linux-amd64.tar.gz

进入钱包目录并创建钱包

创建主网钱包

./grin-wallet init

创建 floonet 测试网钱包

./grin-wallet --floonet init

当你看到如下内容时则说明钱包创建成功，其中 24 个单词为你钱包的助记词，务必安全保存，以后如果需要恢复钱包时需要使用它来进行恢复。

20190105 17:36:35.814 WARN grin_wallet::types - Generating wallet seed file at: /home/yeastplume/.grin/wallet_data/wallet.seed
Your recovery phrase is:

Please back-up these words in a non-digital format.
Command 'init' completed successfully

1.3 Wallet 连接 Grin 节点

连接 Wallet 到本地 Grin 节点

./grin-wallet --floonet -r http://127.0.0.1:13413 info

连接成功后钱包信息如图所示，新钱包所有余额都为 0

  • Confirmed Total 是你当前钱包所有的余额，包括正在等待确认和余额。
  • Awaiting Confirmation 是目前已经广播到 Grin 链上未达到 10 个区块确认的金额，目前暂时不能使用。
  • Locked by previous transaction 是目前正在锁定的金额，比如你收到一笔 30 Grin 以后向另一个人转账 10 Grin，则需要把 30 个 Grin 打包到区块链，其中 10 个转给对方，20 个返回给你的钱包，这时候会有 30 个显示锁定中。

至此，你已经有了一个 Grin 节点和连接到该节点的 Grin Wallet。接下来我们说一下 Grin Wallet 的转账

2、Grin Wallet 转账(文件转账 / Http URL 转账)

2.1 通过文件进行 Grin 转账

如果作为普通用户，在自己的 Mac 或者 Ubuntu 电脑上安装的 Grin 节点和 Grin Wallet，因为本地电脑无法生成可供外网访问的 http URL，所以只能使用文件形式进行 Grin 收款。

Grin Wallet 文件转账主要流程如图所示：

20190715-03.png

  1. 发款人创建转账文件 my_grin_transaction.tx 并分享给收款人
  2. 收款人接受文件并签名，生成 my_grin_transaction.tx.response 分享给发款人
  3. 发款人最终签名文件并广播到 Grin 链

发款人创建 my_grin_transaction.tx 文件，以下命令表示发款人生成向对方转账 10.25 的文件

./grin-wallet --floonet send -m file -d my_grin_transaction.tx 10.25

收款人接受文件，并生成 my_grin_transaction.tx.response 文件分享给发款人

./grin-wallet --floonet receive -i my_grin_transaction.tx

发款人进行最终确认并广播到 Grin 链上

./grin-wallet --floonet finalize -i my_grin_transaction.tx.response

至此，通过文件形式转账 Grin 的流程已经结束，接下来则等待矿工打包确认交易

查看 Grin Wallet 交易记录
./grin-wallet --floonet txs

如图所示，展示了钱包的收付款以及每笔交易状态的记录。由于 Grin 的匿名性，每笔交易看不到收付款人信息

取消交易

如果你想取消某一笔交易，使用如下命令,其中 3 为 ID

./grin-wallet --floonet cancel -i 3
Wallet Check

当取消交易或者主链分叉导致 Wallet 不一致状态时，可以使用 check 命令手动遍历所有区块信息，以确保本地钱包数据库和链上数据保持一致。

./grin-wallet --floonet check

2.2 通过 Http URL 方式转账

如果你的 Grin 节点和 Wallet 创建在云服务器上，并能生成可供外网访问的 Http URL，则可以通过 Http ULR 的方式收 Grin 币。目前的交易所在充提 Grin 时都是使用 URL 的方式进行的，所以你如果想从交易所提 Grin 币，则必须拥有一个可供外网访问的 URL。

收 Grin 币前，先开启 Wallet Listen

默认钱包只监听在本地机器，为了别的机器可以连接到该钱包，需要编辑 ~./grin-wallet.toml 文件 api_listen_interface 字段

把

api_listen_interface = "127.0.0.1"

修改为

api_listen_interface = "0.0.0.0"

然后运行钱包监听

./grin-wallet --floonet listen

或者你也可以传入-e(外部)钱包参数来监听 0.0.0.0

./grin-wallet --floonet -e listen

开启成功后，对方则可以通过外网 IP 地址加端口号给你转 Grin 币了。如下所示，向 http://101.132.243.78:13415 地址转账 1.2 个 Grin floonet 测试币

./grin-wallet --floonet send -d http://101.132.243.78:13415 1.2
