Worldcoin and decentralized identity, DID, are both used for digital identity verification, but they follow different core paths. Worldcoin uses iris scanning to achieve Proof of Personhood, emphasizing that “one person can only have one identity.” DID, by contrast, builds an identity system through on-chain credentials and user controlled data, emphasizing data sovereignty and composability. The two approaches differ fundamentally in verification methods, privacy models, and use cases, making them suitable for different Web3 needs.

World ID is the digital identity protocol in the Worldcoin ecosystem. It generates a unique encrypted identity marker, IrisHash, through iris scanning and uses it to enable Proof of Personhood. By combining biometrics, cryptographic hashing, and zero knowledge proof technology, the system verifies user identity without exposing original biometric data, helping prevent bot attacks and support decentralized identity, DID, applications.

Worldcoin (WLD) is a blockchain based digital identity and crypto economy system that verifies users as “unique real humans” through World ID, also known as Proof of Personhood, and distributes tokens to them. It combines biometrics, decentralized identity, DID, and token incentives to address bot proliferation, identity fraud, and fair participation in the digital economy, making it an important direction in the development of identity infrastructure for the AI era.

Worldcoin uses iris scanning technology to verify identity by generating an encrypted IrisHash, but its handling of biometric data has raised privacy and regulatory concerns. Although the system says it does not store original iris images and uses encryption and zero knowledge proofs to protect data, uncertainties remain around data collection, user consent, and cross border regulation. These issues have made Worldcoin one of the most closely watched risk cases in the digital identity sector.

Both BAT and Google Ads serve the digital advertising market, but they operate in fundamentally different ways. Google Ads relies on a centralized platform to collect user data for ad targeting, with the platform controlling how revenue is distributed. BAT, by contrast, uses the Brave browser to build a more intermediary free advertising ecosystem, redistributing ad revenue among advertisers, users, and content creators while strengthening user privacy through local ad matching. The two models represent different paths: the traditional digital advertising model and the Web3 attention economy model.

Basic Attention Token (BAT) is a utility token within the Brave browser ecosystem. It is used to connect the flow of value among advertisers, users, and content creators. Users earn BAT rewards by viewing privacy preserving ads, advertisers use BAT to pay for advertising, and content creators can receive income through user tips. BAT reshapes the revenue distribution logic of traditional advertising through a token based mechanism, improving ad efficiency and strengthening user privacy protection. It is one of the important use cases of the Web3 attention economy.

The BAT reward mechanism is the core value distribution model within the Brave browser advertising ecosystem. Advertisers use BAT to pay for ads, users earn BAT rewards by viewing privacy preserving ads, and content creators can receive token income through user tips or ad revenue sharing. This mechanism redistributes advertising revenue through blockchain tokens, improves advertising transparency, and gives users a direct return on the value of their attention. It is an important innovation in the Web3 digital advertising model.

Mask Network is a decentralized privacy middleware that runs on Web2 social media platforms, such as Twitter and Facebook. Through its open-source browser extension, it enables encrypted communication, cross-border digital asset transfers, and seamless access to DApps. It allows users to use Web3 features without leaving their existing social interfaces, including sending encrypted red packets, participating in Initial Twitter Offerings, or ITOs, and displaying NFT profiles. As a bridge between Web2 and Web3, Mask Network aims to give users control over their own data and build a decentralized gateway ecosystem.

Mask Network transmits encrypted messages through a hybrid encryption mechanism that combines asymmetric encryption, such as RSA or ECC, with symmetric encryption, such as AES. The sender uses a randomly generated AES key to encrypt the original message locally, then encrypts that AES key with the recipient’s public key and publishes the encrypted ciphertext to the social platform. After the Mask extension detects the ciphertext, the recipient uses their local private key to decrypt the AES key and then restore the original message. Throughout the entire process, the private key remains under the user’s local control. The social platform only serves as a medium for transmitting ciphertext and cannot access the plaintext content.

Initial Twitter Offering (ITO) is a decentralized asset distribution mechanism introduced by Mask Network. It allows project teams to issue tokens directly on Twitter, now X. Built on Mask’s underlying plugin technology, ITO combines blockchain smart contracts with an interactive tweet interface, so users can subscribe to tokens by connecting a wallet without leaving social media. As an innovative model for social token launches, ITO greatly lowers the barrier to participating in early crypto asset distribution and has become an important tool for Web3 traffic conversion and community fundraising.

Shield Protocol is the buyback and supply adjustment mechanism designed by Staynex for the STAY token. By allocating part of the platform’s net revenue to buybacks, token burns, and liquidity locking, it creates a connection between platform revenue and changes in token supply and demand. The mechanism is designed to play a regulatory role in Staynex’s tokenomics model by increasing demand, reducing circulating supply, and improving liquidity.

STAY is the core utility token of the Staynex Web3 social travel ecosystem. It is mainly used for membership staking, platform rewards, and access to ecosystem benefits. Users can stake STAY to unlock Ocean Club membership tiers and receive cashback and exclusive benefits. Staynex also uses Shield Protocol to allocate part of its platform revenue to buybacks, burns, and liquidity locking, linking STAY to the platform’s business performance and building a token model centered on membership demand and revenue feedback.

Staynex (STAY) is a social travel platform that combines Web3, AI itinerary planning, and a membership rewards system. Users can stake STAY to access Ocean Club membership benefits, while Shield Protocol provides long-term value support through a buyback and burn mechanism. By connecting real travel spending with on-chain incentives, Staynex is building a Web3 travel ecosystem.

CHZ’s economic model is driven by demand generated through the issuance and trading of fan tokens. This demand fuels token usage, creating a cycle of value circulation and supply and demand within the ecosystem.

Chiliz enables fans to take a more active role in sports and entertainment by turning engagement into measurable, token-based participation. Through its ecosystem, users can acquire fan tokens, vote on decisions, and interact with clubs in ways that are recorded and executed on-chain.
