With the rapid development of the digital economy, the digitalization of Real World Assets (RWA) has become an irreversible trend. This trend shows particular potential in DeFi, as it allows these assets to be programmatically traded and managed through smart contracts and blockchain technology, enhancing liquidity and market efficiency. However, the integration of RWAs into the DeFi ecosystem faces challenges, mainly due to the multifaceted constraints on the development of Web3 technologies.
Among the numerous challenges in Web3, the issue of fake accounts stands out prominently, posing a significant threat to the security and trustworthiness of the technology. Fake accounts not only compromise user trust but also undermine the overall health of the ecosystem. Their detrimental effects include market manipulation, involvement in money laundering activities, and participation in various fraudulent acts. These activities not only distort market data and user behavior analysis but also result in losses for ordinary users, jeopardizing their financial security. Addressing these challenges is crucial for building a healthy and sustainable Web3 ecosystem, underscoring the importance of strengthening identity verification and account regulation.
Centralized Risks of Traditional KYC
The traditional KYC process also presents several centralized risks. Most of this information is stored in centralized databases, and due to the centralized storage of large amounts of sensitive information, these financial institutions become high-value targets for hackers. Additionally, centralized data management can lead to risks of privacy breaches, especially in cases where data is accessed illegally or mishandled. Lastly, the existence of centralized systems can lead to over-concentration of power, where institutions might abuse this information, such as using data for cross-selling or other commercial activities without customer consent.
With the advancement of blockchain technology, the decentralized advantages of blockchain technology naturally highlight its superiority in avoiding the traditional KYC problems mentioned above. Therefore, finding new decentralized KYC solutions using blockchain technology is particularly important. Decentralized KYC solutions make identity verification more transparent and secure, while minimizing centralized risks. This new form of KYC not only enhances data security and privacy protection but also increases users' control over their own data.
The Tension Between the Cryptocurrency Domain and KYC
In the world of Web3, anonymity was once a core feature, leading many startup cryptocurrency service platforms to initially forego any KYC processes. Platforms like Binance and BitMEX were initially resistant to introducing KYC because they valued user privacy and anonymity. However, as global regulatory bodies have increased their scrutiny of the cryptocurrency industry, these companies have been forced to adopt stricter KYC measures under pressure from regulators in countries like the UK and the USA. This shift has compelled centralized exchanges to either comply with the stringent KYC requirements of various national regulators or cease providing services to users in certain countries.
In the DeFi sector, this tension is particularly evident, as DeFi aims to create a financial system independent of traditional financial intermediaries through decentralization. This system emphasizes that "code is law," using smart contracts to automate transactions, thereby increasing efficiency and reducing costs. However, the lack of KYC processes can make these platforms hotbeds for money laundering and other illegal activities, raising concerns among regulators. Therefore, integrating KYC processes reasonably without sacrificing core decentralization principles and user privacy is a crucial challenge that the DeFi sector must face in its future development.
Web3 Needs More Comprehensive Identity Verification
As Web3 advances, the need for a more comprehensive identity verification system becomes increasingly important. This system needs to be interoperable across different protocols to enable on-chain identity assertions while ensuring comprehensive privacy protection for participants. This way, the identity verification process can effectively utilize the consensus mechanism of blockchain and seamlessly integrate with other crypto protocols. Additionally, combining artificial intelligence with decentralized oracles to automate ongoing KYC processes can significantly improve efficiency without sacrificing compliance and privacy protection.
In the ongoing development and move towards compliance in Web3, privacy protection has long been a significant challenge, particularly in the DeFi sector. The introduction of identity layers has historically posed challenges to anonymity. Most community members believe that publicly disclosing encrypted financial transaction information on a public ledger is unwise, as it fails to provide adequate privacy options for those who do not wish to disclose their personal transaction information. While the creation of identities relies on a trusted party to maintain claims, the process of identity verification can be decentralized. Thus, the path towards Web3 compliance not only preserves the privacy layer but also opens up new possibilities for various identity verification scenarios.
The Initial Intent of Comprehensive Identity Verification in Meta Earth
Meta Earth's vision is to enhance the Human Happiness Index and promote sustainable ecological development. A key objective is to leverage blockchain technology to empower the digital transformation of traditional industries and everyday transaction scenarios, allowing the majority to enjoy the benefits of this digital shift. Achieving this goal requires a comprehensive identity verification system, crucial for ensuring the authenticity and legality of transactions within a digital environment. This also means creating an interactive environment that simulates the real world, where verifying the authenticity and security of user identities is fundamental for attracting users and maintaining the ecosystem's health. For example, the ME platform might involve real estate transactions, among others. Here are several reasons why Meta Earth needs to establish a robust KYC identity verification system:
Traditional Industries on Blockchain: When Real World Assets (RWA) such as real estate, industrial assets, artworks, or other traditional financial assets migrate to Meta Earth, it involves the transfer and management of asset ownership. These transactions require a high level of trust and security.
Without an effective identity verification mechanism, these transactions are susceptible to fraud and abuse. Ensuring the authenticity and verifiability of the identities of the parties involved in the transactions is crucial. This not only helps prevent fraud and money laundering but also ensures the legal compliance and enforceability of the transactions.
Everyday Transaction Scenarios on Blockchain: As everyday activities such as shopping, payments, and social interactions move onto the blockchain, verifying user identities becomes particularly important. For example, any financial activities conducted on Meta Earth, such as lending, insurance, and other financial services, require KYC to prevent identity theft and related financial fraud, thereby enhancing the overall security and trustworthiness of the platform.
Balancing Regulation and Privacy Protection: While pursuing openness and decentralization, Meta Earth must comply with the regulatory requirements for financial services in different regions around the world, especially those concerning Anti-Money Laundering (AML) and Counter-Terrorism Financing (CFT). A robust KYC system helps Meta Earth meet these regulatory requirements without compromising user privacy, balancing the need for privacy protection with regulatory compliance.
Multi-party Collaboration and Cross-sector Integration: In the process of implementing blockchain for everyday transaction scenarios and traditional industries, Meta Earth will likely need to collaborate with entities from multiple industries and various regions. A comprehensive and reliable KYC system can ensure the identity and legality of all parties involved, enhance trust among partners, and facilitate the smooth execution of these cross-border collaborations.
Meta Earth's Native DID Solution
From the inception of its underlying network, Meta Earth has natively constructed support for a decentralized KYC with the DID protocol — the ME ID Protocol. This provides the entire Meta Earth ecosystem with a robust decentralized identity issuance and verification system, with ME ID being the first identity verification use case aimed at addressing the shortcomings of traditional financial KYC.
Firstly, homomorphic encryption algorithms are used to pre-encrypt user KYC data locally. Users employ homomorphic encryption algorithms (such as BFV homomorphic encryption) locally to encrypt biometric data like facial images and voice prints, generating irreversible ciphertext. Homomorphic encryption allows operations to be carried out on encrypted data, enabling servers to perform validation and comparison operations on ciphertext without being able to decrypt and obtain the original plaintext data.
Secondly, the entire KYC process is authenticated using AI algorithms, and no one can access the KYC data during this process. Once a DID identity is formed, it is stored on the blockchain in segmented, fine-grained encrypted blocks, only extracting and disclosing necessary features, minimizing the transmission of sensitive information. Moreover, no third party can reverse-engineer the encryption to access user KYC information. Only when departments related to the user's KYC jurisdiction need to retrieve information, can it be decrypted and accessed through multi-signature authorization by the ME DAO, to comply with legal financial regulatory scrutiny.
Furthermore, Meta Earth introduces an assertion-based zero-knowledge proof generation and verification method to further protect user privacy, meeting the dual needs of identity assertion and privacy protection. This technology allows users to verify the validity of their identity or certain attributes without revealing any personal data beyond what is necessary.
Lastly, verifiers can only perform validation operations using ciphertext and cannot decrypt the plaintext, reducing the risk of data leakage.
Given the diversity in technology levels and regulatory requirements worldwide, as well as the regional characteristics of identity verification and privacy protection, the ME Network will also actively assist operators globally to establish KYC infrastructures that comply with local policies.
By addressing these key issues in decentralized KYC, Meta Earth will be able to offer a safer, more trustworthy platform, providing users with enriched interactive experiences, while promoting the successful implementation of its business model and further expanding its adoption worldwide.
Strengthening Trust and Security for a Sustainable Future
The verifiable personal sovereign identity provided by ME ID is the cornerstone for building a decentralized future. It integrates decentralization with KYC compliance, and this infrastructure will facilitate the genuine value flow between traditional global asset markets and cryptocurrencies, serving as a crucial link for the integration of the real world with Web3.0.
Against this backdrop, Meta Earth is progressively establishing a more authentic, transparent, and sustainable Web3 digital world. By constructing a modular, high-performance, and highly scalable multi-dimensional fusion underlying value network — the ME Network — it supports the high-concurrency big data processing demands of traditional industry applications. Within this network, a decentralized encrypted digital identity system, ME ID, is built natively, balancing identity assertions with user privacy data protection. Based on this identity verification system, a co-governance mechanism that upholds "personal sovereignty and equality for all" can be realized. This facilitates an economic model that ensures a basic income unconditionally and indiscriminately. Ultimately, this aims to enhance the Human Happiness Index and promote sustainable ecological development, catalyzing a new digital era closely integrated with Web3.0 based on genuine human relationships.
