Metaverse元界區塊鏈推出全球領先的數字身份及BaaS服務

領先的公有區塊鏈Metaverse元界，創始以來一直致力於打造集智能資產，數字身份和價值中介為一體的公有鏈。2017年2月11日，元界主網正式上線，經過7個月的努力，元界團隊於2017年9月正式推出全球領先的數字身份及BaaS服務。

China's leading public blockchain Metaverse, has been committed to creating a combination of smart property, Avatar and oracle as one public blockchain since its inception.

Metaverse mainnet was officially launched in 11th February 2017. After only 7 months, the Metaverse team releases the world's leading digital identity function「Avatar」 and BaaS service in September 5th.

數字身份：區塊鏈中的缺失環節

Digital Identity: blockchain』s missing link

隨著互聯網的興起，用戶名和密碼成為我們在各平台進行身份驗證的常見方式。各類中心化機構和第三方授權驗證方式繁瑣，彼此身份系統不互通，並且個人身份信息的安全性和隱私性也難以保證，重複登記也浪費了大量的時間和資源。在這種情況下，基於區塊鏈技術的數字身份正被進行廣泛研究，為行業內存在的相應問題提供解決方案。

As Internet emerges, usernames and passwords have become a common method of digital identity authentication. Data sharing and repeated register of centralized institutions as well as third-parties still exist, which can』t soundly guarantee security and privacy of personal information and also wastes a lot of time and resources.

在當前的區塊鏈生態系統中，存在一系列不同的區塊鏈協議和實施方案。所有身份問題都會進入這樣一個程序，即：證明誰擁有什麼和誰做了什麼。雖然匿名性在比特幣這樣的協議中具有一些優勢，但是當區塊鏈技術及其應用在全球實施時，匿名性並不是一個強大的特質。我們需要知道我們正在處理的是什麼，我們通過名字對人們的身份進行識別，而不是一串數字。而在許多公有區塊鏈協議中，身份問題常常被忽略。這是一個缺失的環節，因為它可以讓區塊鏈數字資產的概念蓬勃發展，並讓區塊鏈上的金融應用在數字銀行體系和其它金融機構中發揮作用。

There are a number of different blockchain protocols and implementations in the current blockchain ecosystem. All identity issues must follow this process: to prove who owns what, and who does what with whom. While anonymity has some advantages in certain protocols such as Bitcoin, it will not be a powerful trait when blockchain technology and its applications are implemented globally. We need to know what we are dealing with, and we identify people by their names rather than a string of numbers. The 『missing link』 in blockchains is therefore identity, which is often overlooked in many public blockchain protocols: it would allow the concept of digital assets to flourish and financial applications to display their full potential in online banking and other financial institutions.

元界數字身份的特點

Feature of 「Avatar」 Digital Identity

元界的數字身份將基於現有的區塊鏈生態體系搭建，並根據元界區塊鏈提供的底層功能，圍繞BaaS及錢包來開展數字身份的應用，以期為各行各業提供可驗證、可授權的基礎設施服務。

Avatar (Digital identities) will be based on the Metaverse ecosystem and its underlying functions. Its applications will be centered around BaaS and the Metaverse Wallet, aiming to offering verifiable and authoritative infrastructure services for all walks of life.

數字身份是用戶所擁有的主私鑰所對應的賬戶的Profile信息的統稱。Profile擁有一個全網唯一標識，在元界中，我們稱該標識為DID（Digital Identity，可類比比特股的別名）。數字身份包括Oracle的角色和普通用戶的角色，任何Oracle和普通用戶都可以通過構建數字身份參與到數據身份的應用中來。

An avatar is the general name given to an account』s profile information, corresponding to the master private key belonging to a user. Each profile has a unique identifier called DID (Digital Identity, similar to an alias for Bitshares) in Metaverse. Avatar include the roles of Oracle and ordinary users.

與數字身份相關聯的有效鏈下數據的登記，大致需要以下四步：

1.擁有數據的用戶在元界建立其數字身份，並提供其自有格式的數據，將數據打包提交給負責數據鑒定與背書的Oracle；

2.具備鑒定數據資格的Oracle（數字身份的一種）鑒定該數字身份所提交的數據的有效性、真實性；

3.經數據所有者和Oracle簽名后的資產將通過主私鑰與數字身份綁定；

4.其他用戶可以在數據所有者的授權之下，查看該數據資產所代表的詳細信息。

Registering valid off-chain data associated with an avatar requires the following four steps:

1, Users with data must establish his/her avatar on Metaverse, provide data with its own format, and submit this data to an Oracle who is responsible for data authentication and endorsement.

2, Oracles (one of the Avatar) qualified to endorse data will verify the validity and authenticity of the submitted data;

3, After the data is signed by its owner and an Oracle, it will be bound with the owner』s avatar through master private keys.

4, other users can view detailed information about this data after the data owner』s gives his authorization.

元界區塊鏈推出BaaS服務

Blockchain as a Service

元界首次提出了BaaS（區塊鏈即服務）的概念，即企業或個人可以根據自己的實際需求，向區塊鏈解決方案供應商定製區塊鏈服務。元界的BaaS框架主要面向商業用戶，隨著元界基礎設施的不斷完善，其服務對象可能不止於此類用戶，商業用戶的劃分也不能再以傳統的形態來判斷，它將可以是任何主體，即廣義上的數字身份。

The concept of BaaS (Blockchain as a Service) was first proposed by Metaverse, that is to say enterprises or individuals can customize blockchain services for blockchain solutions providers according to their actual needs.

Metaverse』s BaaS (Blockchain as a service) framework mainly caters to business users, such as individuals or businesses with transaction or asset management needs. Business users can no longer be grouped as they traditionally were and BaaS must be able to cater to any user, even digital identities.

我們相信數字身份及Bass的應用場景將會涉及保險、借貸、審計、徵信等領域，隨著元界數字身份體系的不斷完善，未來，元界將會提供更多基礎性的服務設施，以便更多第三方開發者能夠基於元界區塊鏈進行應用插件的開發，讓更多普通用戶能夠便捷地使用我們的錢包及身份管理服務。

We are convinced that digital identities and Bass application would be used in the fields including insurance, borrowing, audit as well as credit. Metaverse continues to improve its digital identity system and will expand on the available basic services so that more third-party developers can develop plug-in applications based on the Metaverse blockchain, increasing the ease of use of our Wallet and identity management services for ordinary users.
