# IRIS Network

The IRIS network is an internet of blockchains intended to provide a technology foundation that facilitates construction of distributed business applications.

![Figure of IRIS Network](https://github.com/irisnet/irisnet/blob/master/images/chap2-1.png?raw=true)

The IRIS network is part of the larger Cosmos network -- all zones in the network would be able to interact with any other zone in the Cosmos network over the standard IBC protocol. By introducing a layer of service semantics into the network, we are going to provide an innovative solution that enables a whole new set of business scenarios, which would result in an increase in scale and diversity of the Cosmos network.

# IRIS Hub

At the "center" of the IRIS network is a blockchain known as the *IRIS Hub*, which is a Proof-of-Stake (PoS) blockchain built on Cosmos SDK and Tendermint. It will be the first regional hub that connects to the Cosmos Hub as one of its zones. The IRIS hub is equipped with a service protocol that coordinates on-chain transaction processing with off-chain data processing and business logic execution. We have also enhanced the IBC protocol to facilitate cross-chain invocation of those off-chain services, if so desired.

The service protocol and enhanced IBC protocol could eventually be contributed back into Cosmos SDK, allowing SDK users to develop blockchains that are compatible with the IRIS network.

Client-facing, programming language specific SDKs will also be available to make it easy to provide and consume off-chain services within the IRIS network.

# IRIS Tokens

The IRIS hub has its own native token known as *IRIS*. It is designed to serve three purposes in the network.

* **Staking.** Similar to the ATOM token in the Cosmos Hub, the IRIS token will be used as a staking token to secure the PoS blockchain.

* **Transaction Fee.** The IRIS token will also be used to pay fees for all transactions in the IRIS network.

* **Service Fee.** It is required that service providers in the IRIS network charge service fees denominated in the IRIS token.

It is intended that the IRIS network will eventually support all whitelisted fee tokens from the Cosmos network, which can be used to pay the transaction fees and service fees.

# IRIS Services

*IRIS Services* (a.k.a. "iServices") are introduced to bridge the gap between the blockchain world and the conventional business application world, mediating the complete lifecycle of off-chain services -- from their definition, binding (provider registration), invocation, to their governance (profiling and arbitration).

## Lifecycle

* **Definition.** Definition of what an off-chain iService can do in terms of an Interface Definition Language (IDL) file.

* **Binding.** Declaration of the location (address), pricing and QoS of a provider endpoint that implements a given iService definition.

* **Invocation.** Handling of consumer requests to and provider responses from a given iService provider endpoint.

## Providers
*Providers* are network users who offer the implementation of one or more iService definitions and often act as *adaptors* of off-chain services and resources located in other public and consortium chains, as well as in enterprise legacy systems. Providers monitor and process incoming requests and send responses back to the network. A provider could at the same time act as a consumer by sending requests to other providers. As planned, providers would be required to charge a fee for any services they might offer, and the service fee, by default, would be priced in the IRIS token.

## Consumers
*Consumers* are those users who consume iServices by sending requests to designated provider endpoints and receiving responses from providers in question.

## Profilers
*Profilers* are special consumers who act on behalf of the IRIS Foundation Limited, a Hong Kong incorporated company limited by guarantee that takes the lead in building the IRIS network. Profilers are the sole users authorized to invoke iServices in the *profiling mode*, which is intended to help create and maintain objective provider profiles that consumers refer to for provider screening.

## Arbitrators
*Arbitrators* are self-declared users who, working collectively, arbitrate consumer complaints against provider performance. The details about the arbitration mechanism are being actively worked on, please keep an eye on our [whitepaper](resources/whitepaper-en.md).

# IRIS网络

IRIS网络是一个区块链互联网它旨在提供便于构建分布式商业应用程序的技术基础

![IRIS网络图](https://github.com/irisnet/irisnet/blob/master/images/chap2-1.png?raw=true)

IRIS网络是更大的Cosmos网络的一部分 - 网络中所有分区都能够通过标准IBC协议与Cosmos网络中的任何其他分区进行交互通过在网络中引入一层服务语义我们将提供一种创新的解决方案支持全新的业务场景从而增加Cosmos网络的规模和多样性

# IRIS枢纽

在IRIS网络的中心是一个称为 *IRIS枢纽* 的区块链它是一个基于Cosmos SDK和Tendermint构建的Proof-of-StakePoS区块链它将成为第一个连接Cosmos枢纽的地区级枢纽IRIS枢纽配备了服务协议该协议将链上的交易处理与链下的数据处理和业务逻辑执行进行协调我们还增强了IBC协议以促进那些链下服务在有需要的情况下被跨链调用

服务协议和增强的IBC协议最终可以回馈到Cosmos SDK中允许SDK用户开发与IRIS网络兼容的区块链

我们也会提供面向客户的针对特定编程语言的SDK方便在IRIS网络内轻松提供和使用链下服务

# IRIS通证

IRIS枢纽有自己的原生通证称为 *IRIS*它旨在为网络中的三个目的服务

* **Staking** 与Cosmos Hub中的ATOM通证类似IRIS通证将用作Staking通证以保护PoS区块链的安全运行

* **交易费用** IRIS通证也将用于支付IRIS网络中所有交易的费用

* **服务费** IRIS网络中的服务提供者需要以IRIS通证为单位收取服务费

IRIS网络最终将支持来自Cosmos网络的所有列入白名单的费用通证它们可用于支付交易费用和服务费用

# IRIS服务

引入 *IRIS服务*又名iServices”)的目标是弥合区块链世界与传统商业应用世界之间的鸿沟居中协调链下服务的整个生命周期 - 从定义绑定提供者注册),调用直到它们的治理描画和仲裁)。

## 生命周期

* **定义** 根据接口定义语言IDL文件定义链下iService可以做什么

* **绑定** 声明实现给​​定iService定义的提供者端点的位置地址),定价和服务质量

* **调用** 处理针对给定iService提供者端点的消费者请求以及相应的提供者响应

## 提供者
*提供者* 是提供一个或多个iService定义实现的网络用户通常充当位于其他公有链联盟链以及企业现有系统中的链下服务和资源的 *适配器*它们监听和处理传入的请求并将响应发送回网络提供者可以通过向其他提供者发送请求来同时充当消费者按照计划提供者将被要求为他们可能提供的服务收取费用默认情况下服务费将以IRIS通证定价

## 消费者
*消费者* 是那些使用iServices的用户他们向指定的提供者端点发送请求并接收相关提供者的响应

## 描画者
*描画者* 是代表IRIS基金会行动的特殊消费者作为注册在香港的非盈利机构IRIS基金会牵头推进IRIS网络的建设描画者是仅有的被授权以 *描画模式* 调用iServices的用户该模式旨在帮助创建和维护客观的提供者画像”,便于消费者筛选提供者时参考

## 仲裁员
*仲裁员* 是自我声明的一类用户他们通过协作为消费者对提供者绩效的投诉进行仲裁有关仲裁机制的细节正在积极设计中请关注我们的[白皮书](resources/whitepaper-zh.md)。
