Mist是以太坊官方提供的钱包应用，为geth的GUI版本。官方下载地址：https://github.com/ethereum/mist/releases，本文中使用的是0.9.3版本。

连接私有链

启动Mist，过一段时间后会出现如下错误：

为什么会这样呢？原因如下：

Mist启动后查找本地默认ipc是否存在（Mac默认文件为$HOME/Library/Ethereum/geth.ipc；Windows默认文件为.\pipe\geth.ipc；Linux默认文件为/.ethereum/geth.ipc），如果存在则发送rpc请求获取相关数据，否则将从公有链网络下载Genesis block等信息初始化本地链并启动节点。

而在本例中，节点初始化和启动均使用了自定义目录$HOME/share/q-btc/data，因此Mist没有连接到私有链网络，而是连接到公有链获取信息初始化并启动节点。

此时，本地节点和Mist启动的新节点均使用的是默认端口30303，发生了端口冲突，因此出现上面的错误。

为了使Mist连接到本地节点，可以在启动Mist时设--rpc参数指定ipc文件：

# cd /Applications/Mist.app/Contents/

注意：“Sanity check failed for Geth Error”错误信息标识Mist所需的geth版本信息与从私有链获取到的geth版本信息不匹配，暂没发现该错误对后续应用造成影响，可以先忽略。Mist界面启动后，右上角显示PRIVATE-NET，已经成功连接到私有链网络中了，点击LAUNCH APPLICATION，进入Mist主界面：可以看到界面显示已经有一个账户，拥有1590个以太币，与之前geth命令行返回的信息一致。

创建账户

账户是一对公钥/私钥对，用于进行挖矿、交易、存储ether等活动。之前已经通过Geth创建了一个账户，该账户为Main Account，挖矿获得的ether默认存在该账户。账户可以有多个，下面通过Mist创建另一个账户至此，新创建了一个账户ACCOUNT3，该账户地址为0xD12B5885d62BB06c76A1699E560C37AC06Ee81C4。

账户文件保存在--datadir目录中的keystore目录中：

Chris:keystore zhangli$ ls $HOME/share/q-btc/private_chain/data/keystore

创建交易

从MAIN ACCOUNT向ACCOUNT3转入一些ether，会创建一个交易：

输入MAIN ACCOUNT账户密码，SEND TRANSACTION后创建一个交易，可以在MAIN ACCOUNT账户的交易列表中看到：点击该交易，可以看到交易信息：交易ID为0x8c50622c1648b46c7f94cc9aca8eded3af3231eb611d61bfeaae2e9ffefa702f，此时console会显示日志：

> INFO [xx-xx|22:26:19] Submitted transaction                    fullhash=0x8c50622c1648b46c7f94cc9aca8eded3af3231eb611d61bfeaae2e9ffefa702f recipient=0xD12B5885d62BB06c76A1699E560C37AC06Ee81C4

该交易一直处于灰色，显示“0的12确认区块”，不会有任何变化，而ACCOUNT3的余额一直未0。这是因为目前没有任何节点进行挖矿操作，因此不会将该交易放入私有链中。

通过console启动挖矿：

> miner.start(1)

开始挖矿后，可以看到交易开始产生进度，信息也开始有所变化：当交易完成时，交易状态如下，同时ACCOUNT3的余额变为200：
