亦来云（Elastos）是下一代 Web 3.0 平台，致力于打造基于区块链技术的去中心化智能万维网（SmartWeb）。
亦来云以主侧链结构、多层共识、智能合约共识计算等区块链技术，为平台提供安全可信的基础；并在其上构建了去中心化的身份、通讯、存储、计算等平台服务，旨在提供一个支撑分布式应用的系统平台，同时提供良好的用户隐私保护和数据安全，成为数据资产化浪潮的引擎。

一.项目介绍

项目特点

亦来云计划实现的是区块链驱动的智能万维网。亦来云智能万维网可以分成以下四个层次：

1.亦来云区块链及智能合约：
亦来云区块链为其生态提供信用、交易基础服务，采用主链+侧链的架构，主链只有限地支持用于数字货币交易的智能合约，从而实现降低执行合约占用地计算资源。侧链可以支持智能合约，各个侧链可以独立设计智能合约功能， DApp运行在侧链上，每个应用都可以独立开设一个侧链，主链为侧链提供支持，方便资产在主链和侧链间转移。区块链采用比特币联合挖矿机制，矿池通过部署联合挖矿代码，矿工同时向比特币和亦来云提供工作量证明，无需耗费额外算力。

2.Elastos Carrier（去中心化 P2P 网络）：
为亦来云生态提供去中心化互联网基础服务。包括去中心化域名服务、去中心化计算服务、去中心化存储服务。Elastos Carrier 采用UDP 的透明 NAT 穿越技术，及相关辅助设施，可以实现任意两个节点直接连接。

1）UDP 用户数据报协议，应用程序发给网络层数据后就不保留数据的不可靠传递数据的协议。
2）NAT （Network Address Translator）把内部私有的网络 IP 地址翻译成公有网络 IP 地址的技术，外网公有地址是全球唯一的，能在公网被路由（用户传输机制）。
3）UDP 保证了数据传输不会被拦截的情况下，利用 NAT 实现 P2P 通信。

Carrier可以简单的说是一种P2P的通信框架，主要包括网络通信协议、P2P 存储接口调用、节点的连接等，开发者重新定义了网络通信协议以及权限，保障了 P2P 通信的安全与认证问题，其次，该部分代码提供了大量接口，包括存储、应用接入等等，都为开发者提供了去中心化网络的基本框架，为二次开发提供了可能。在代码库中有大量 Carrier SDK 代码，该部分代码主要为传统 APP 以及操作系统的接入提供可能，该部分代码为不同的编程语言、操作系统等等提供了对于 Elastos Carrier 的调用方式以及认证方式。

3.Elastos OS 及 Runtime：
Elastos OS面向移动设备的操作系统，可以提供原生的亦来云生态编程环境支持。Elastos OS可以安装在裸机上。通过 Elastos OS可以方便访问 Elastos Carrier网络。Elastos OS禁止应用创建进程，不允许应用直接访问 TCP/IP，每一个基于该操作系统的用户权限都会被隔离开，在没有交互的必要性时，该操作系统只有本地操作，不会进行网络通信。由系统自动创建和查找部署于本地、周边、云里的微服务，自动生成远程调用及事件回调，规避从第三方应用或服务发起网络攻击的可能性。Elastos Runtime 将亦来云虚拟运行环境通过沙箱（计算机领域的一种安全机制，为运行中的程序提供隔离环境）与原生 OS 进行隔离。

Elastos Runtime 为 DApp 开发者提供了代码的运行时环境以及代码的开发框架，可以认为 Elastos Runtime 是 C++ 版的 Java 虚拟机和 Java 架构，也可以称为 CVM ，即为基于 Elastos 的开发者提供了类似于 Java 的编译器、代码仓库、编程框架等内容，让开发者基于该编程环境开发，开发者不改变现有操作系统的情况下，使用 Elastos Runtime 提供的虚拟运行环境开发、测试、运行亦来云去中心化应用。Elastos Runtime 将利用沙箱与 OS 原生环境相隔离。计划将提供 Elastos Runtime for Android, Elastos Runtime for iOS, Elastos Runtime for GNU/Linux，给开发者使用。

4.Elastos SDK：
传统意义的APP，可以通过包含亦来云的SDK扩展能力，获得身份鉴权、可信记录等区块链典型能力。主要为传统APP以及操作系统的接入提供可能，为不同的编程语言、操作系统提供了对于Elastos Carrier的调用方式以及认证方式。

共识机制

亦来云主链共识机制：
亦来云主链采用 DPoS 和与比特币联合挖矿的 PoW 共识算法，联合挖矿意味着他们可以直接利用比特币的安全保障，比特币矿工们提交工作量证明的时候也允许去验证亦来云区块，之前已经被其他几个数字加密货币项目所采用。

亦来云的侧链可以使用任意的共识机制：
1）目前亦来云团队已经开发出了基于PoW共识的侧链，可以接入主链完成基于SPV和DPoS 的充值和提币操作。这个基于PoW的侧链可以借助主链的算力来保障自己的安全，主链算力的使用权交给基于DPoS共识选举出的仲裁人，每个仲裁人轮流对侧链进行基于 PoW 的打包出块。

2）亦来云同时在规划开发基于 DPoS 共识的侧链，侧链上 DPoS 共识中的代理人由主链的仲裁人来担任，仍然相当于通过主链保证侧链的安全，只是减少了挖矿的过程，会获得更快的出块速度。侧链的每个节点都可以通过挂接的主链SPV模块来获得主链对仲裁人的投票信息，从而对仲裁人的合法性达成共识。

主侧链间转账：
1）亦來云主链到侧链的转账基于SPV来实现,侧链上需要集成主链的SPV 模块,用于随时同步主链区块以及主链上向侧链的转账交易，每个侧链节点都会同步主链的所有区块头，再加上merkle证明路径以及交易信息，就可以从数据结构和算法的角度完成对转账交易的去中心化共识。

2）亦來云侧链到主链的转账安全通过主链的仲裁人机制来保证，主链的持币人共同选举出一定数量的一仲裁人，仲裁人负责对侧链到主链的提币交易进行签名，多数的仲裁人签名就可以解锁主链上从代表侧链的账户向普通账户转账的「提币交易」。仲裁人通过在主链上投票选举产生，并且定期轮换。

亦来云区块链

亦来云区块链采用主链、侧链设计方案，即每个应用都可以独立开设一个侧链。亦来云区块链提供内置的、完善的、易用的侧链支持，侧链有多种共识算法模块供用户选择，侧链可以发行代币，主链和侧链可进行双向资产转移。所有侧链与主链共享算力，因此所有侧链都具有和主链一样的安全性。同时整体系统能耗可以实现最小化，避免分头挖矿带来巨大能源消耗和碳排放的问题。

1）交易和区块设计：
亦来云区块链结构参考了现有的经典的数字货币系统设计，包括区块验证必要的前一区块头哈希、交易默克尔树根哈希、用于工作量证明算法的计数器（Nonce）、时间戳、难度目标等内容，链式的存储结构能够让交易获得所有累积在上面的工作量证明的保护，并且实现去中心共识的目标，进而成为全自动的信用生产体系。

同时整体上采用主链、侧链相结合的设计思路。将验证脚本从交易结构中拿出去，减少了交易空间占用，避免了延展性攻击。侧链是亦来云众多 DApp 运行的基础，因此亦来云主链结构要提供对侧链的支持，要能够方便资产在主链和侧链间转移。

2）联合挖矿：
亦来云区块链采用比特币联合挖矿机制，比特币作为主链（ParentBlockchain），亦来币作为辅链（Auxiliary Blockchain），矿池通过部署联合挖矿代码，矿工同时向比特币和亦来云提交工作量证明，无需耗费额外算力即可享有双重奖励，增加了矿工在采矿竞争中的收益。

通过联合挖矿机制，亦来云区块链拥有极其强大的算力保障。为全球区块链创新，特别是亦来云生态提供信用生产的基础服务。

3）代币分配方案：
亦来云代币（ELA Coin），简称亦来币（ELA），是亦来云区块链上的原生代币，用于交易、支持数字资产、支付区块链交易手续费等。使用 ELA 作为亦来云代币的基本单位，中文名称：亦来币或者艾拉。也用 SatoshiELA作为亦来币最小货币单位，并缩写为 Sela，中文名字是：赛拉。

为了弥补类似用户钱包丢失等自然损耗的流通量，以及保持其支撑的智能经济生态微量通胀等，亦来币每年保持固定同比 4% 的增发。增发的亦来币将在比特币联合挖矿中伴随每 2 分钟左右的区块生成同步产生。为了保持亦来云生态的可持续发展，自亦来云区块链正式上线后两年内，此部分亦来币将在亦来云基金会和矿工之间按比例分配，亦来云基金会拥有 30%，矿工拥有70%。

4）侧链：
除了支持第三方能够比较方便的在亦来云公链上构建侧链外，亦来云本身还会架构一些提供基础服务的侧链，比如 ID 服务、Token 发行服务、快速支付服务以及数字资产交易服务等等，我们称之为亦来云区块链集群服务。

在主链和侧链的接口中，交易转账是其最核心的部分。从主链向侧链转账，意味着要把主链资产转变为侧链资产，转账目标地址是对应侧链在主链上的联合签名地址，转账过程需要保证转账交易能够自动被侧链识别并为转账人在侧链对应账号充值对应价值的侧链代币。

通过随机秘密以及对应的哈希，我们可以构造必须提供秘密才能解锁的交易脚本。为了控制联合签名地址上亦來币的安全性，这个“联合签名地址”会限制只能发起的“提款转账”交易。

5）智能合约:
在主链上提供强大的智能合约会导致每个节点要获得整个网络的最新状态，就要把未运行的智能合约都运行一遍，而只有打包交易的矿工运行合约才能得到交易费，所以对于单纯验证的节点来说是在浪费计算资源，如果合约调用次数频繁或者数量庞大，都会对执行合约带来巨大压力甚至无法实现。

为了避免这样的问题，亦来云主链只有限地支持用于数字代币交易的智能合约。侧链可以支持智能合约，而且各个侧链可以独立设计其智能合约功能，比如支持NEO区块链的 NeoContract。

Elastos Carrier：去中心化P2P网络

ElastosCarrier为亦来云生态提供去中心化互联网基础服务。其节点可以运行在任何网络环境中，包括家庭或者办公环境的局域网内部，采用基于 UDP 的透明 NAT 穿越技术，及相关辅助设施，可以实现任意节点都可以被连接，同时也可以实现任意两个节点间的直接连接。

基础服务包括去中心化域名服务、去中心化计算服务、去中心化存储服务。为开发去中心化应用程序（DApp）提供了基础性的支持。用户可以拥有自己的数据，拥有自己的计算，充分保护了用户隐私。同时，也可以随时把自己的设备通过亦来云区块链租借给他人，根据计算量、存储量获得对应的亦来币激励。

Elastos OS：安全的通用操作系统

Elastos OS 是以安全为核心目标的，面向 IoT 设备、树莓派等创客设备、移动设备等的通用操作系统。提供原生的、完整的亦来云生态编程环境支持。最新的第三版从 2013 年 5 月开始产品化迭代周期，已达到 Beta 版水平，测试运行于 Moto X（XT1085）手机、Lamobo-R1S 智能路由器之上，全部源代码规模超过千万行。

安全方面，ElastosOS 禁止应用直接创建进程，不允许应用直接访问TCP/IP，由系统自动创建和查找部署于本地、周边、云里的微服务，自动生成远程调用及事件回调，规避从第三方应用或服务发起网络攻击的可能性，并隔离病毒传播。

Elastos OS 提供了原生的、完善的去中心化应用开发支持，可以方便访问 ElastosCarrier 网络，获取所需基础服务，方便访问 ElastosChain，获取信用和交易服务。开发出来的 DApp 可以方便使用亦来币进行交易，同时也可以方便处理其他数字资产，比如：程序代码、数据、电子书、音视频、游戏道具等，包括确权、交易、流通。

系统采用 C/C++、JAVA、HTML5/JS 三类语言并重的开发模式，其 C++编程 API 基本对应安卓 Java API，实现云、管、端三位一体统一管理。JavaScript、Java 还是 C/C++ 语言写的应用程序模块相互调用，无需手工编写 JNI，真正做到“一次编程、到处运行”。

代币用途

亦来币将用于交易、支持数字资产、支付区块链手续费等：
1）在亦来云上开发的 DApp 将会使用 ELA 去支付所使用的域名注册、搜索引擎、页面排名、数字资产的 UUID（通用唯一识别码）的获取等服务，将会用 ELA 来补贴带宽，IPFS 等等。

2）亦来云生态系统合作项目必须锁定不少于 2%-5% 的该项目的代币，这些代币的 20%（被转换成 ELA）将会被用于亦来云基金的发展，80% 的实际项目代币将会奖励给 ELA 的持有者。

3）用户可以用亦来云代币在亦来云上注册 ID，并以此购买服务，还可以参加在亦来云上进行的项目和产品的代币售卖；

4）ELA 将会作为奖励在亦来云上开发去中心化应用的开发者的主要货币。

二.评述

亦来云（Elastos）是一个将互联网作为底层基础设施的操作系统。强调网络通讯与应用计算分离，禁止应用程序直接访问网络，从而杜绝大部分肆虐在互联网上的病毒攻击（尤其是DDoS）。亦来云的区块链采用主链+侧链结构搭建底层信任，所有侧链与主链共享算力，因此所有侧链都具有和主链一样的安全性。应用通过 Elastos OS/Runtime 连接 Elastos Carrier (去中心化 P2P 网络），将 DApp 运行在相互隔离的进程、通信受限的沙箱环境中。网络数据必须通过、安全、可信、可以识别的身份通道发送，这些身份识别和鉴权都来自于区块链身份 ID。

1. Project Introduction

Elastos is the next generation Web 3.0 platform, dedicated to building a decentralized intelligent World Wide Web (SmartWeb) based on blockchain technology. ).
Elastos uses blockchain technologies such as main-side chain structure, multi-layer consensus, and smart contract consensus calculation to provide a safe and trustworthy foundation for the platform; and builds decentralized identity, communication, and storage on top of it , computing and other platform services, aiming to provide a system platform that supports distributed applications, while providing good user privacy protection and data security, becoming the engine of the wave of data assetization.

Project Features

What Elastos plans to achieve is a blockchain-driven intelligent World Wide Web. The Elastos Smart World Wide Web can be divided into the following four levels:

1. Elastos blockchain and smart contracts:
The Elastos blockchain provides basic credit and transaction services for its ecosystem. Adopting a main chain + side chain architecture, the main chain only supports limited smart contracts for digital currency transactions, thereby reducing the computing resources occupied by contract execution. Side chains can support smart contracts, and each side chain can independently design smart contract functions. DApp runs on the side chain. Each application can independently open a side chain. The main chain provides support for the side chain, making it easier for assets to be transferred between the main chain and the side chain. Inter-chain transfer. The blockchain adopts the Bitcoin joint mining mechanism. The mining pool deploys the joint mining code, and the miners provide proof of work to Bitcoin and Elastos at the same time without spending additional computing power.

2.Elastos Carrier (decentralized P2P network):
Provides decentralized Internet basic services for the Elastos ecosystem. Including decentralized domain name services, decentralized computing services, and decentralized storage services. Elastos Carrier uses UDP's transparent NAT traversal technology and related auxiliary facilities to achieve direct connection between any two nodes.

1) UDP User Datagram Protocolprotocol, an unreliable data delivery protocol that does not retain the data after the application sends it to the network layer.
2) NAT (Network Address Translator) is a technology that translates internal private network IP addresses into public network IP addresses. The external public network address is unique in the world and can be routed on the public network (user transmission mechanism).
3) UDP ensures that data transmission will not be intercepted, and NAT is used to achieve P2P communication.

Carrier can simply be said to be a P2P communication framework, which mainly includes network communication protocols, P2P storage interface calls, node connections, etc. The developers have redefined the network communication protocols and permissions to ensure P2P communication. Secondly, this part of the code provides a large number of interfaces, including storage, application access, etc., which provide developers with the basic framework of a decentralized network and provide the possibility for secondary development. There is a large amount of Carrier SDK code in the code base. This part of the code mainly provides the possibility of accessing traditional APPs and operating systems. This part of the code provides the calling method and authentication method for Elastos Carrier for different programming languages, operating systems, etc. .

3. Elastos OS and Runtime:
Elastos OS is an operating system for mobile devices and can provide native Elastos ecological programming environment support. Elastos OS can be installed on bare metal. Elastos Carrier network can be easily accessed through Elastos OS. Elastos OS prohibits applications from creating processes and does not allow applications to directly access TCP/IP. Each user's permissions based on this operating system will be isolated. When there is no need for interaction, the operating system will only operate locally and will not communicate with the network. . The system automatically creates and searches for microservices deployed locally, nearby, and in the cloud, and automatically generates remote calls and event callbacks to avoid the possibility of network attacks from third-party applications or services. Elastos Runtime isolates the Elastos virtual running environment from the native OS through a sandbox (a security mechanism in the computer field that provides an isolation environment for running programs).

Elastos Runtime provides DApp developers with a code runtime environment and a code development framework. It can be considered that Elastos Runtime is a C++ version of the Java virtual machine and Java architecture. It can also be called CVM, which is based on The developers of Elastos provide Java-like compilers, code warehouses, programming frameworks, etc., allowing developers to develop based on this programming environment. Developers can use Elastos Run without changing the existing operating system.The virtual operating environment provided by time is used to develop, test, and run Elastos decentralized applications. Elastos Runtime will utilize a sandbox to isolate itself from the native OS environment. The plan will provide Elastos Runtime for Android, Elastos Runtime for iOS, and Elastos Runtime for GNU/Linux for developers to use.

4. Elastos SDK:
Apps in the traditional sense can obtain typical blockchain capabilities such as identity authentication and trusted records through the expansion capabilities of Elastos’ SDK. It mainly provides the possibility of accessing traditional APPs and operating systems, and provides calling methods and authentication methods for Elastos Carrier for different programming languages and operating systems.

Consensus mechanism

Elastos main chain consensus mechanism:
Elastos main chain adopts DPoS and PoW consensus algorithms that are jointly mined with Bitcoin. Joint mining means They can directly take advantage of Bitcoin's security guarantees. Bitcoin miners are also allowed to verify Elastos blocks when submitting proof of work, which has been adopted by several other digital currency projects before.

Elastos' side chain can use any consensus mechanism:
1) At present, the Elastos team has developed a side chain based on PoW consensus, which can be connected to the main chain to complete SPV and DPoS based on Deposit and withdrawal operations. This PoW-based side chain can rely on the computing power of the main chain to ensure its own security. The right to use the main chain's computing power is given to arbitrators elected based on the DPoS consensus. Each arbitrator takes turns packaging the side chain based on PoW. Out of blocks.

2) Elastos is also planning to develop a side chain based on the DPoS consensus. The agent in the DPoS consensus on the side chain is served by the arbitrator of the main chain, which is still equivalent to guaranteeing the side chain through the main chain. It is safe. It just reduces the mining process and will result in faster block production. Each node of the side chain can obtain the main chain's voting information for the arbitrator through the attached main chain SPV module, thereby reaching a consensus on the legitimacy of the arbitrator.

Transfer between main and side chains:
1) Transfer from Elastos main chain to side chain is based on SPV. The side chain needs to integrate the SPV module of the main chain to synchronize the main chain at any time. Blocks and transfer transactions from the main chain to the side chain. Each side chain node will synchronize all block headers of the main chain. Together with the merkle proof path and transaction information, the transfer transaction can be completed from the perspective of data structure and algorithm. decentralized consensus.

2) The security of transfers from the Elastos side chain to the main chain is guaranteed by the arbitrator mechanism of the main chain. The currency holders of the main chain jointly elect a certain number of arbitrators, who are responsible for the opposite side. Sign the currency withdrawal transaction chained to the main chain, and a majority of arbitrators can signTo unlock the "coin withdrawal transaction" on the main chain that transfers funds from the account representing the side chain to the ordinary account. Arbitrators are elected by voting on the main chain and rotate regularly.

Elastos Blockchain

Elastos Blockchain adopts a main chain and side chain design, that is, each application can independently open a side chain. The Elastos blockchain provides built-in, complete, and easy-to-use side chain support. The side chain has a variety of consensus algorithm modules for users to choose from. The side chain can issue tokens, and the main chain and side chain can perform two-way asset transfers. All side chains share computing power with the main chain, so all side chains have the same security as the main chain. At the same time, the overall system energy consumption can be minimized to avoid the huge energy consumption and carbon emissions caused by separate mining.

1) Transaction and block design:
The Elastos blockchain structure refers to the existing classic digital currency system design, including the previous block header hash necessary for block verification, Transaction Merkle tree root hash, counter (Nonce) used for proof-of-work algorithm, timestamp, difficulty target, etc. The chained storage structure allows transactions to be protected by all proof-of-work accumulated on it, and Achieve the goal of decentralized consensus and then become a fully automated credit production system.

At the same time, the design idea of combining main chain and side chain is adopted as a whole. Taking the verification script out of the transaction structure reduces the transaction space and avoids scalability attacks. Side chains are the basis for the operation of many Elastos DApps. Therefore, the Elastos main chain structure must provide support for side chains and facilitate the transfer of assets between the main chain and side chains.

2) Joint mining:
The Elastos blockchain adopts the Bitcoin joint mining mechanism, with Bitcoin as the main chain (ParentBlockchain) and Elastos as the auxiliary chain (Auxiliary Blockchain). By deploying joint mining code, the mining pool allows miners to submit proof of work to both Bitcoin and Elastos at the same time. They can enjoy double rewards without spending additional computing power, which increases the miners' profits in the mining competition.

Through the joint mining mechanism, the Elastos blockchain has extremely powerful computing power guarantee. Provide basic services for credit production for global blockchain innovation, especially the Elastos ecosystem.

3) Token distribution plan:
ELA Coin, referred to as ELA, is the native token on the Elastos blockchain and is used for transactions , support digital assets, pay blockchain transaction fees, etc. Use ELA as the basic unit of Elastos tokens, Chinese name: Elastos or Ella. SatoshiELA is also used as the smallest currency unit of Elastos, and is abbreviated as Sela. The Chinese name is: Sela.

In order to make up for the natural loss of circulation, such as the loss of user wallets, and to maintain the micro-inflation of the smart economic ecology it supports, Elastos maintains a fixed 4% year-on-year additional issuance every year. Additional Elastos will be issued every 2 minutes or so in Bitcoin joint mining.The right block is generated synchronously. In order to maintain the sustainable development of the Elastos ecosystem, within two years after the official launch of the Elastos blockchain, this part of the Elastos coins will be distributed proportionally between the Elastos Foundation and the miners. The Elastos Foundation owns 30%, miners own 70%.

4) Sidechain:
In addition to supporting third parties to easily build sidechains on the Elastos public chain, Elastos itself will also build some sidechains that provide basic services. For example, ID services, Token issuance services, fast payment services, digital asset trading services, etc., we call them Elastos blockchain cluster services.

In the interface between the main chain and the side chain, transaction transfer is the core part. Transferring funds from the main chain to the side chain means converting the main chain assets into side chain assets. The transfer target address is the joint signature address of the corresponding side chain on the main chain. The transfer process needs to ensure that the transfer transaction can be automatically recognized by the side chain and Recharge side-chain tokens of corresponding value to the transferor's corresponding account in the side-chain.

With a random secret and the corresponding hash, we can construct a transaction script that must provide the secret to unlock it. In order to control the security of Elastos on the joint signature address, this "joint signature address" will limit the "withdrawal transfer" transactions that can only be initiated.

5) Smart contracts:
Providing powerful smart contracts on the main chain will cause each node to run all unrun smart contracts in order to obtain the latest status of the entire network, and Only miners who package transactions can get transaction fees by running contracts, so it is a waste of computing resources for nodes that simply verify. If the number of contract calls is frequent or large, it will put huge pressure on executing the contract or even make it impossible to implement it.

To avoid such problems, the Elastos main chain only has limited support for smart contracts for digital token transactions. Side chains can support smart contracts, and each side chain can independently design its smart contract functions, such as NeoContract that supports the NEO blockchain.

Elastos Carrier: Decentralized P2P Network

Elastos Carrier provides decentralized Internet basic services for the Elastos ecosystem. Its nodes can run in any network environment, including LANs in home or office environments. It uses UDP-based transparent NAT traversal technology and related auxiliary facilities, so that any node can be connected, and any two nodes can also be connected. direct connection between.

Basic services include decentralized domain name services, decentralized computing services, and decentralized storage services. Provides basic support for the development of decentralized applications (DApp). Users can own their own data and their own calculations, fully protecting user privacy. At the same time, you can also rent your equipment to others through the Elastos blockchain at any time, and receive corresponding ELA coin incentives based on the amount of computing and storage.

Elastos OS: A secure general-purpose operating system

Elastos OS is a general-purpose operating system with security as its core goal and oriented to IoT devices, maker devices such as Raspberry Pi, and mobile devices. Provide native and complete Elastos ecological programming environment support. The latest third version started its product iteration cycle in May 2013 and has reached the Beta level. It is tested and run on Moto X (XT1085) mobile phone and Lamobo-R1S smart router. The total source code size exceeds 10 million lines.

In terms of security, ElastosOS prohibits applications from directly creating processes and does not allow applications to directly access TCP/IP. The system automatically creates and searches for microservices deployed locally, nearby, and in the cloud, and automatically generates remote calls and events. Callbacks to circumvent the possibility of network attacks from third-party applications or services and isolate virus spread.

Elastos OS provides native and complete decentralized application development support, allowing easy access to the Elastos Carrier network to obtain required basic services, and easy access to ElastosChain to obtain credit and transaction services. The developed DApp can facilitate transactions using Elastos, and can also facilitate the processing of other digital assets, such as program code, data, e-books, audio and video, game props, etc., including rights confirmation, transaction, and circulation.

The system adopts a development model that pays equal attention to three languages: C/C++, JAVA, and HTML5/JS. Its C++ programming API basically corresponds to the Android Java API, achieving unified management of the cloud, pipe, and terminal. Application modules written in JavaScript, Java or C/C++ call each other without having to manually write JNI, truly achieving "program once, run anywhere".

Token usage

Elastos will be used for transactions, supporting digital assets, paying blockchain fees, etc.:
1) DApps developed on Elastos will ELA will be used to pay for services such as domain name registration, search engines, page rankings, and the acquisition of UUID (Universal Unique Identification Code) for digital assets. ELA will be used to subsidize bandwidth, IPFS, etc.

2) Elastos ecosystem cooperation projects must lock no less than 2%-5% of the project’s tokens, and 20% of these tokens (converted into ELA) will be used for Elastos Due to the development of Cloud Fund, 80% of the actual project tokens will be awarded to ELA holders.

3) Users can use Elastos tokens to register IDs on Elastos and use them to purchase services, and can also participate in the token sales of projects and products on Elastos;

4) ELA will be used as the main currency to reward developers who develop decentralized applications on Elastos.

2. Comment

Elastos is an operating system that uses the Internet as the underlying infrastructure. It emphasizes the separation of network communication and application computing, and prohibits applications from directly accessing the network, thereby eliminating most virus attacks (especially DDoS) raging on the Internet. Elastos' blockchain uses a main chain + side chain structure to build underlying trust. All side chains share computing power with the main chain, so all side chains have the same security as the main chain. The application connects to Elastos Carrier (decentralized P2P network) through Elastos OS/Runtime, running DApp in a sandbox environment with isolated processes and limited communication. Network data must be sent through a secure, trustworthy, and identifiable identity channel. These identifications and authentications come from blockchain identity IDs.
