mixin

The Mixin BFT-DAG network reference implementation, the Trusted Execution Environment is not integrated into this repository yet.

Install golang and setup GOPATH following this guide https://golang.org/doc/install.

$ git clone https://github.com/MixinNetwork/mixin.git

The mixin command is both the kernel node and tools to communicate with the node RPC interface.

Mixin Kernel Address

Mixin Kernel address are a pair of ed25519 keys, following the CryptoNote protocol. To create a new address use the createaddress command.

$ mixin createaddress

address:	XINJkpCdwVk3qFqmS3AAAoTmC5Gm2fR3iRF7Rtt7hayuaLXNrtztS3LGPSxTmq5KQh3KJ2qYXYE5a9w8BWXhZAdsJKXqcvUr
view key:	568302b687a2fa3e8853ff35d99ffdf3817b98170de7b51e43d0dcf4fe30470f
spend key:	7c2b5c97278ed371d75610cccd9681af31b0d99be4adc2d66983f3c455fc9702

Share the address to receive assets from other Mixin Kernel addresses, and keep view key and spend key privately and securely.

Both the view key and spend key are required to spend the assets received from others, and the view key iteself is sufficient to decode and view all the transactions sent to address.

Sign and Send Raw Transaction

Basic Mixin Kernel transaction is similar to the transaction in Bitcoin, with following format.

{
  "version": 1,
  "asset": "a99c2e0e2b1da4d648755ef19bd95139acbbe6564cfb06dec7cd34931ca72cdc",
  "extra": "34366362393932382d653636632d343966392d386165632d366462366137346666663638",
  "outputs": [
    {
      "type": 0,
      "amount": "115.06849309",
      "script": "fffe01",
      "accounts": [
        "XINPXu5NBXszhpZDRJ8iA26TbQ2oWTSq1tXqKKeVeYWgLSz8yXGTtVhMogynYytoMewYVFR541wauLhy1YV33zg445E49YA7"
      ]
    }
  ],
  "inputs": [
    {
      "hash": "20001842d6eff5129c11f7c053bf1209f0267bf223f1681c9cb9d19fc773a692",
      "index": 11
    }
  ]
}

This is the same UTXO model used in Bitcoin, but with different field names. Among them version, type and script should not be modified unless you know some advanced topics.

Compact the raw transaction JSON and sign it with the private view and spend key as following.

$ mixin signrawtransaction -n mixin-node:8239 \
    -key 0d48c96d383d325a97eea5295cbf3afa7766c49db477b68fd8032ff7f59b0b00d77e434f96f3f42c2d1796662c7cc90497feaf3863a5815f27ba49fd5e29b906 \
    -raw '{"version":1,"asset":"a99c2e0e2b1da4d648755ef19bd95139acbbe6564cfb06dec7cd34931ca72cdc","extra":"34366362393932382d653636632d343966392d386165632d366462366137346666663638","outputs":[{"type":0,"amount":"115.06849309","script":"fffe01","accounts":["XINPXu5NBXszhpZDRJ8iA26TbQ2oWTSq1tXqKKeVeYWgLSz8yXGTtVhMogynYytoMewYVFR541wauLhy1YV33zg445E49YA7"]}],"inputs":[{"hash":"20001842d6eff5129c11f7c053bf1209f0267bf223f1681c9cb9d19fc773a692","index":11}]}'

Start a Kernel Node

To start a node, create a directory mixin for the config and network data files, then put the genesis.json, nodes.json and config.toml files in it.

The main net genesis.json, nodes.json and an example config.example.toml files can be obtained from here, you only need to put your own signer spend key in the config.toml file.

Change the consensus-only option to false will allow the node to start in archive mode, which syncs all the graph data.

$ mixin help kernel

NAME:
   mixin kernel - Start the Mixin Kernel daemon

USAGE:
   mixin kernel [command options] [arguments...]

OPTIONS:
   --dir value, -d value   the data directory
   --port value, -p value  the peer port to listen (default: 7239)

Local Test Net

This will setup a minimum local test net, with all nodes in a single device.

$ mixin setuptestnet

$ mixin kernel -dir /tmp/mixin-7001 -port 7001
$ mixin kernel -dir /tmp/mixin-7002 -port 7002
$ mixin kernel -dir /tmp/mixin-7003 -port 7003
$ mixin kernel -dir /tmp/mixin-7004 -port 7004
$ mixin kernel -dir /tmp/mixin-7005 -port 7005
$ mixin kernel -dir /tmp/mixin-7006 -port 7006
$ mixin kernel -dir /tmp/mixin-7007 -port 7007

python教程：mixin详解

1.什么是Mixin 在面向对象编程中，Mixin是一种类，这种类包含了其他类要使用的方法，但不必充当其他类的父类。其他类是如何获取Mixin中的方法因语言的不同而不同。所以有时候Mixin被描述为’include’（包含）而不是 inheritance（继承）。 Mixins鼓励代码重用，并且可以用于避免多重继承可能导致（“如钻石问题”）的继承歧义，或者解决一个缺乏对一种语言的多重继承的支持。m
Mixin

Mixin 在组件和组件之间有时候会存在相同的代码逻辑，我们希望对相同的代码逻辑进行抽取，在vue2和vue3中都支持的一种方式那就是使用Mixin来完成，Mixin提供了一种非常灵活的方式来分发vue组件中的可复用功能，因为一个Mixin对象中可以包含任何组件选项，当组件使用该Mixin对象时，所有Mixin对象的选项都将被合并进入该组件本身的选项中。合并规则如果Mixin对象中的选项和组件
关于Mixin

关于Mixin设计模式今天读到一篇文章，关于python的Mixin设计模式，文中提到动态加载类、动态加载函数等动态加载的概念，不是很理解，在度娘的指导下有了一些己见。遂抄起键盘做此记录，可能和真正的Mixin有偏差，甚至毫不相干…欢迎老师或同学帮忙解读一下，我确实想知道到底啥意思，干嘛用的。 Mixin 是一种编程开发模式和Java的接口类似有一款冰淇淋，提供一些基础口味（主要功能类）有香
前端开发：Vue混入(mixin)的使用

前言在前端开发中，作为开发者关于Vue框架的使用不必多说，Vue的框架也是目前最为好用的框架之一，虽然Vue3.0已经成为了主流版本（Vue2.0和Vue3.0还是有不少差别的），但丝毫不影响开发使用。本篇博文分享一个关于Vue相关的比较重要的知识点----混入(mixin)，该内容在实际开发中比较常用，也比较重要，所以需要灵活运用，尤其是刚接触Vue不久的开发者甚为重要。混入/混合的概念 V
Vue 源码之 mixin 原理

mixin的意思是混入，是指将事先配置的选项混入到组件中，然后与组件中的对象和方法进行合并，也就是对组件进行了扩展，也可以理解为是将一段重复的代码进行抽离，然后通过混入的形式达到复用的效果，它有两种混入形式，分别是 Vue.mixin({})全局注册和组件的 mixins选项，那么在 Vue 中，他们是怎么进行合并，具体实现是怎么样呢，这篇文章将进行讲解，相信你一定会有所收获；首先是入口文件，在

一、什么是mixin 通俗的讲，mixin(mix-in)是一种新的语言特性，表面类似多继承，使用with关键字对类添加一些功能。官话mixin是在多个类层次结构中重用类代码的一种方法。mixin(mix-in)是为面向对象程序设计语言中的类提供了方法的实现。其他类可以访问mixin类的方法、变量而不必成为其子类。Mixin 的作用就是在多个类层次结构中重用类的代码，很好的解决了单继承带来的代码冗
