As a new generation of innovative technology, blockchain has accelerated its integration with traditional industries, and technologies and applications such as blockchain finance, blockchain logistics, and blockchain AI are constantly emerging. With the continuous enrichment and implementation of blockchain application scenarios, it can be said that blockchain will play an increasing role in people's production and life, and more and more industries and enterprises will face the challenges brought by blockchain. opportunities and challenges to come. Whether it is the Internet era or the future blockchain era, one of its characteristics is "digitization". The basis of digital activities is the user’s “digital identity”. We must ensure the authenticity and validity of personal digital identities, as well as a series of activities, transactions and other information related to them. Therefore, the development of digital identity systems is also the general trend in the future, and blockchain technology will provide a series of feasible solutions with its decentralization, multi-party knowledge, non-tampering, openness, transparency, traceability and other characteristics. Based on this, Bridge was born. By reviewing the white paper, we found that Bridge is an open, distributed network of trusted machines where users provide real-world value and applications through behaviors, standards, and execution mechanisms. The system enables users to deploy business processes that comply with existing standards and regulations What is Bridge? BRIDGE is a secure digital identity on the blockchain. The BRIDGE protocol facilitates interactions between bridging users, trusted verification partners and integrated network partners. This combination creates a prosperous, scalable and secure digital identity authentication platform. Bridge's private blockchain will provide secure asset processing, aiming to use smart contracts to ensure trusted execution and regulatory compliance. The system will be composed of trusted virtual machines that provide user-accessible functionality for enterprise-level business operations. Bridge will begin issuing digital identities that allow individuals and businesses to participate securely and freely while building a broad network of authentic trust. The company will centrally issue and manage early identities to facilitate the establishment of a reliable and stable foundation. This governance system will allow self-sovereign identities to be recognized and managed for wider adaptability and diversity. The first service offered on the protocol is the layered tokenization of these identities, which, coupled with contract logic developed by Bridge Protocol, will allow for the initial issuance of tokens, using KYC to ensure compliance with prescribed information. What are the characteristics of the digital identity and KYC services developed by Bridge? In the development of digital identity, the Bridge protocol uses blockchain technology to ensure safe and reliable identity verification. With simple API integration, businesses no longer need to rely on third parties to authenticate their users. For KYC services, the BridgeChrome extension allows businesses to verify certification documents and their users. The marketplace supports vendors that provide related services. Competition drives competitive pricing while ensuring user data is never stored. Moreover, easy-to-read developer documentation can be integrated directly on BridgeNetwork. Use BridgePassport to verify work history, social media presence and more. How does Bridge verify identity? The Bridge extension allows users to easily send their NEO address along with their verified identity. If a business has to verify age, that's what they see! This ensures businesses get what they need to be compliant. Users are bound to a blockchain using a digital ID that serves as their digital signature. At this time, the user's identity will be recorded in the NEO smart economy and cannot be changed or transplanted. BridgeID is reusable. No more sending Passport to multiple exchanges or knowing who the recipient is. Verify once and you have a digital identity. Send a public address through BridgePassport to complete KYC verification! The Bridge protocol was developed for the global community. Already supported in more than 250 countries/regions! What innovations has Bridge made in terms of legal compliance? Complying with existing laws in different countries will be a challenge. Regulations such as the General Data Protection Regulation (GDPR) in Europe require that user data must be portable, portable and secure. Bridge will create a marketplace to support new legal services in token sales, wills, employment agreements, and more. This will promote the continuous development and updating of various matters to adapt to new regulations and legal changes. Contributors to the legal process will receive native tokens as rewards for producing new microservices. . Participants will be able to see the auditor's background and their license status to practice law. Bridge’s tokens will be used as payment to the legal team and process microservices. Bridge will connect software developers and legal experts on a platform that facilitates collaboration and community benefit. In short, identity authentication is the core of personal information applications, and the Bridge of blockchain technology provides a new solution for identity authentication. Since the blockchain is non-tamperable and traceable, it will completely protect personal information, improve the credibility of digital identities, and ensure the privacy and security of personal information to a large extent. Bridge will also provide reliable token sale templates and better procedures for KYC participants. Microservices will reduce regulatory scrutiny and compliance costs while delivering high-quality products by designing storefronts that meet community needs. The author believes that BRDG has broad development prospects and looks forward to its performance in the potential area.
