zkID Wallet: Achieving Self-Sovereignty over Personal Data

The zkID Wallet, developed by zCloak Network, is designed to help users achieve self-sovereignty over their personal data. Users can store any Verifiable Credential that adheres to the Credential Format Standard in the zkID Wallet and access these credentials through common APIs. Moreover, users can intuitively monitor how their data is being used, thereby preventing loss and leakage of information.

Understanding Digital Wallets

A digital wallet is a tool, either an app or a device, that empowers individuals or organizations to manage their digital identities and credentials. It secures user communications with other entities and provides control over how their verifiable credentials are shared.

zkID Wallet is a privacy-centric wallet that enables users to manage their Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) securely. It provides users with full control over their data, ensuring data sovereignty.

Managing DIDs with zkID Wallet

zkID Wallet securely manages users' DID Accounts, referred to as 'accounts'. Accounts can only be created using a mnemonic phrase, but can be restored using the mnemonic phrase and a DID-Keys File, which is automatically generated when an account is created.

Users can own multiple accounts and use each account's keys to sign and create reliable communication channels with others through 'Message Encryption and Decryption'. The DID-Keys File contains several keys, each with different functions and generated under different signature schemes.

zkID Card

The zkID Card is an innovative digital identity tool that empowers organizations to issue and manage W3C-standard credentials while protecting individual data ownership and privacy. This platform not only streamlines the credential management process for businesses and institutions but also places the power of personal data back into the hands of individuals, ensuring they have full control over their information in a wide range of digital interactions.

Valid ID: Ensuring Organizational Trust and Transparency

Valid ID is an innovative identity platform developed by zCloak Network. It is designed to link your entity identity to a W3C DID in a manner that is both cryptographic and legally binding. This platform is powered by identity attestation from multiple parties, ensuring a robust and reliable identity verification process.

The entity profile on Valid ID is controlled by your private key, providing you with complete control over your identity. Additionally, you can add more keys and roles under your entity profile, creating a tree of trust for your project or organization. This system enhances the security and transparency of organizational identities in the digital world.

What is SBT?

Soulbound Tokens (SBTs) are digital identity tokens representing the unique traits, features, and achievements that comprise a person or entity. Issued by "Souls," which correspond to blockchain accounts or wallets, these tokens are non-transferable.

The concept of Soulbound Tokens (SBT) was proposed in May 2022 by Ethereum co-founder Vitalik Buterin, lawyer Puja Ohlhaver, and E. Glen Weyl, an economist and social technologist. They unveiled their ideas in a whitepaper titled “Decentralized Society: Finding Web3’s Soul," elucidating the foundation of a fully-decentralized society (DeSoc) governed by its users. SBTs could serve as everyday credentials, representing a person's identity using blockchain technology. They can encompass a range of information, including medical records and work history. The wallets that hold or issue these records are known as “Souls.”

SBTs aim to expand the NFT concept beyond mere financial or status symbols. They create a unique, non-transferable token representing a person or entity's reputation. Unlike NFTs, which symbolize assets and property, SBTs hold no monetary value and cannot be traded once issued to a wallet.

What is zk-SBT?

zk-SBT, or Zero-Knowledge Soulbound Token, serves to verify that a user's identity meets certain requirements without exposing their private information.

At zCloak Network, user identity data is protected with W3C verifiable credentials, incorporating a built-in merkle tree data structure for functions such as selective disclosure and ZKP computation. These credentials are private by default, stored in the user's device for data sovereignty, and can be issued/attested by a trusted organization without tokens or gas fees. They only require an ECDSA signature, making them quick and easy for everyday use.

When it's necessary to utilize personal identity data for on-chain applications, such as validating age for Decentralized Finance (DeFi) or social platforms, it's vital to transfer this data securely to the blockchain without compromising personal privacy. This scenario provides an optimal use case for Zero-Knowledge Proofs (ZKPs).

A consistent pattern can be observed in such instances: private data, once attested, undergoes computation through a zkProgram on a Zero-Knowledge Virtual Machine (zkVM), which then allows for the disclosure of the computational result instead of the raw data itself.

From the perspective of a verifier, the authenticity of two elements needs to be established: the data itself and the accuracy of the computation. The authenticity of the data can be confirmed through the signature of your verifiable credential, while the computation's accuracy is validated by the ZKP.

A zk-SBT is generated following the successful verification of both the ZKP and the attester's signature. Therefore, rather than providing detailed personal information such as "Jack, from Australia, age 23," a zk-SBT can be minted that simply validates you as an adult from Oceania. By altering the zkProgram, you can create proofs of various attributes about yourself with relative ease.

Conclusion

zCloak Network is at the forefront of data privacy and security in the Web3 space. By leveraging zero-knowledge proof technology and offering innovative solutions like zkID Card Center, STARK-Based zkVM, ValidID, and Legit ID, zCloak Network ensures that
