最近 DID(decentralized identity,去中心化身份)话题特别火,融资新闻也一个接一个。关于 DID 这个概念要如何理清却颇有争议,尽管处于这样的发展早期,很多理念并未完全明晰,不过对于一些已经出现的比较明显的困惑,我们有必要罗列出来,一起尝试看看,拨开 Web3 身份的技术迷雾。Next.ID 社区希望通过系列文章邀请大家讨论:用户到底需要什么样的 DID,或者说什么样的 DID 体系;Web2 的用户迁往 Web3 面临着什么样的迁移成本;Web3 DID 能给用户带来什么在 Web2 中无法获得的东西。MetaMask 钱包是 DID?据不完全披露,钱包领头羊 MetaMask 目前的月活用户数,起码是 3 千万以上的级别。这导致了大部分的 dApp,很自然的希望通过 MetaMask 来做身份层。而这个想法显然有非常多的挑战,毕竟 MetaMask 只是想做一个钱包而已。 先不论 MetaMask 有没有动机和动力,愿意维护这样海量级别的公共 API 来给 dApp 调用。一个始终绕不过去的,横亘在用户面前的大难题是:作为 EOA 类(external...

Next.ID, the world’s first protocol offering Decentralized-Identity-as-a-Service (DIaaS)
is moving into beta testing. It is a decentralized identity aggregation protocol that integrates all Web2 and Web3 digital identities, offering a comprehensive and verifiable identity database for open-source developers and projects to innovate and build dApps on.
As the world’s first DIaaS, Next.ID creates an identity infrastructure that securely aggregates users’ identities into Avatars, making it the primary touch point for interfacing with any app or dApp.

Next.ID’s Avatars exist independently from Web2 and Web3, using a blockchain-like model to retain data integrity. This allows Next.ID to connect to all Web2 and Web3 platforms, aggregating all identities in a fully-agnostic way, unifying them into one single decentralized identifier (DID).
Welcome to the future of Digital Identity.
The ideal DIaaS System must be built with an architecture that prioritizes identity safety and data privacy
A universal Digital Identity management system must consolidate identifiers across chains and platforms in both Web2 & Web3 so identity data can be useful and meaningful
Next.ID recognizes the strengths of multiple approaches to identity (including Verifiable Credentials and Soulbound Tokens) and combines them by creating a sensible “Layer 0” for identities, ensuring that there will always be interoperability between different identity systems, held together by one unifying standard.
It is trustless, and we welcome all developers to audit the code on Github. If you like what you see, come build with the community.
Just as people are infinitely dynamic, Next.ID allows users to create Avatars that are infinitely interoperable across both Web2 and Web3 platforms.
Just as people recognize social groupings (e.g. age, race, nationality), Next.ID builds a framework that allows self-identification.
While Avatars who operate within a framework may sound like a national identity system, complete with social security numbers and Big Brother’s watchful eyes, there are a few key differences that show how Next.ID empowers users to own their identities and is not enslaved by them.
Avatars are
Cryptographic key pairs, making them tamper-proof and unhackable
Used on an opt-in basis, meaning you can create as many or as few of them as you want
Usable and operationable across any platform that supports integration with Next.ID
In short, it is designed to on-board as many users as possible, helping them to create digital autonomy and credibility.


To understand why Next.ID is vital for the next evolution of the internet, please read Why We Need To Own Our Digital Identities In A Decentralized World.
Next.ID’s capabilities can today be experienced by anyone. SwapChat, a Next.ID alpha test partner, is an instant messaging dApp across all Web3 pages that allows users to chat with buyers and sellers on OpenSea.
By integrating a DIaaS like Next.ID, SwapChat users now are able to negotiate prices with buyers and sellers via their Avatars on OpenSea, allowing for more efficient price discovery. Users can also use Avatars to discover communities via Twitter and Discord, leveraging SwapChat’s integration of multiple social platforms.
The list of protocols and dApps using Next.ID is growing weekly. Here are just some of them:
Mask Network — Permissionless platform that bridges Web2 users to Web3
KNN3 — Social graph data solution for Web3 relational data exploration
RSS3 — Content syndication protocol that allows aggregation of Web2 and Web3 content
SwapChat/Web3MQ — Cross-platform chat protocols that allow users to send messages and group chats on OpenSea and Twitter to realize social NFT trading
Web3.bio — Frontend profile page for Web3 identities
.bit — Web3 data container and naming service that enables users to link ENS and other identity services
Note: Next.ID is actively looking to grow its developer and partner ecosystem. Please reach out to us at developer@next.id.
ProofService — Ensure data integrity with cryptography
ProofChain follows a blockchain-like model to retain data integrity, using cryptography and the private-public key pairing system. This ensures that only users with the right private keys will be able to add to the data in each “block”.
ProofService and every change in its history are fully visible on Arweave, true to the Next.ID community’s commitment to full transparency for its protocols.
KVService — Organize and make sense of the data provided by users
As users and protocols read and write data using Next.ID, KVService sets up a framework to organize the information neatly. This enables smoother frontend usage of Next.ID, as well as allows developers a clearer understanding of how Next.ID can be utilized.
RelationService — Enable comprehensive identity queries and social use cases
RelationService is an aggregation of existing IDs, ID queries, and IDs bound to and in parallel to Next.ID, opening up a range of possibilities for integration with external protocols and creating greater Web3 native social use cases. Developers can access the prototype of RelationService server here.
If you’re reading this even in the bear market, we have a proposal for you: build something that lasts.
Digital-Identity-as-a-Service will be the cornerstone on which Web3 will be built, as users get increasingly familiar with a digital economy. While the most recent bull run provided us with completely new and innovative liquidity mining primitives, it lacked sustainability. A sustainable future with true digital ownership is exactly what Next.ID is building.
Next.ID is looking for experienced developers who want to build on Next.ID as a public good, to create a framework that empowers users, and to create a digital society that stands apart from traditional constraints.

Phase 1 (Now-Dec 2022)
Integrate more Web2 platforms, starting with: Discord, Medium, and TikTok
Debut a user-facing demo dApp (Web3.bio) that showcases the full suite of Next.ID’s capabilities
Enlarge our RelationService database to aggregate more verifiable connections from other DID services and databases, making search queries more efficient and trustworthy.
Lay the groundwork for Next.ID to operate as an open-source community governed as a Decentralized Autonomous Organization (DAO).
Phase 2 (2023 and beyond)
Build out the developer ecosystem, encouraging developers to ideate and execute projects in the Next.ID community
Co-develop projects with the community
Expand Next.ID adoption and applications in social media, gaming, security, and asset management
Phase X (TBD)
Build the framework for decentralized P2P nodes to enable users to self-host their data
Develop into a full-fledged DAO, allowing the community to decide a future roadmap.
