Government IDs such as Coinbase, Binance which are already KYC’ed.
Web2 professional platforms like github, linkedin, etc.
For biometric verification, gitcoin uses civic pass which is a which is an encrypted video selfie to proof uniqueness of a person. | Yes, they answer proof of unique humanness using civic pass which is a video KYC and Government IDs using centralized exchanges KYC. | For attestations, they mostly use web3 credentials, with github, linkedin, google, and discord for web2 verification. | It is designed to be privacy preserving because they issue stamps after verifying creds of different identity solutions. | Prevent sybil attacks, gitcoin grants. | No native token, Gitcoin uses the GTC token for funding and governance but Passport itself doesn’t have a token. | Sybil resistance and reputation scoring across decentralized platforms. User has to score > 20 to prove them as unique human which can be done by verifying stamps. | DID, web2 identity verification, wallet connections, and attestations. | | Worldcoin | Biometric data (iris scans) linked to World ID. | Biometric iris scan is the core method, ensuring each person is unique. | Biometric data (iris), minimal web3 usage at present. | Privacy-preserving, claims to not store iris scans but uses cryptographic hashes for verification. | Universal basic income (UBI) distribution using WLD token and Sybil resistance. | Worldcoin (WLD), utility as a governance and incentive token within the Worldcoin ecosystem. | Unique biometric-based identity verification and wants to onboard millions of users using UBI. | Biometric hardware (Orb), Zero-knowledge proofs (ZKPs), DID, zk-SNARKs. | | Proof of Humanity | Combines photo and video KYC and receives humanity ID. | Verified through crowd-sourced challenges to video proofs of identity. | Only web2 data points i.e photo and video of a particular person to receive a humanity ID. | Data is stored in ipfs which is a decentralized storage. We upload there and share it as video and photo format. | To create a trusted list of verified humans by having users submit their name, photo, video and also giving them $UBI token by participating in governance.
These list of verified humans now have benefits which includes secure online voting, fair UBI distribution, a more authentic social media experience, and more. | UBI (Universal Basic Income), used to distribute income and participate in governance, take part in community decision, etc.
Eg: https://gov.proofofhumanity.id/t/tokenomics-for-ubi/19?filter=summary | The unique thing about them is they are using compete web2 way of KYC using video and photo submission but using storage as ipfs which is a decentralized storage. + community based attestation (crowd sourcing) | smart contract to interact after submission of video, ipfs for decentralized storage. | | Sismo
Sismo | Uses privacy-focused identity attestations from both web2 and web3. Eg they had given badge for power user of rhino.fi, Ethereum power user zk badge, gitcoin donor zk badge, etc. | Yes, Sismo offers a ZK SBT Badge, which is a "proof of humanity" badge. A ZK Badge is a non-transferable token that represents an attestation, such as being part of the Proof of Humanity registry.
There are different data points for each SBT badge, eg: ZK SBT badge requires POH registry, and Ethereum power user zk badge requires etc burnt in fees more than 10. | Aggregates data from both web2 (social media) and web3 (wallets, dApps) which is power user of popular dapps, early user of sismo zk badge, etc. | Yes, they are privacy preserving and has data vault. User can choose selective disclosure to what they want to share to applications.
Data Vault functions as the prover in proving schemes, enabling the generation of zero-knowledge proofs (ZKPs) that attest ownership of Data Sources. | Creating private, anonymous identities for applications and governance plus help projects fight sybils plus help users also to not disclose all their information. | No token at this time.
Sismo already has been shutdown from september 1st. | The most unique thing about them is selective disclosure and zk badges which they offer. | Zero-knowledge proofs (ZKP), verifiable credentials, DID, selective disclosure. | | Civic Pass | Video selfie associated with a wallet, provide government issued ID and video selfie. | Yes, they answer proof of unique humanness using civic pass first verification which is video selfie completed with a wallet. | Most of it is web2, for eg, uploading government id, proving liveness using video selfie, and proving uniqueness using video selfie associated with wallet. | They claim to store the video selfie as 3D facemap which is securely stored in encrypted format in civic’s server that cannot be used without consent. | Identity verification, Integration with dApps, Compatibility with polygon.
Identity verification is used to verify transactions, build trust, and prevent fraud. | CVC (Civic Token), used for identity verification services within its ecosystem. | Government-level ID verification with a video selfie and wallet associated with the profile. | Verifiable credentials, web2 KYC integration, DID, zk-SNARKs. | | Privado or Polygon ID | They verify using 3D facescan if you are a live human. | To proof uniqueness they provide option to do 3d facescan off chain or onchain, which is signing with wallet and doing a 3d facescan. | All the verification steps is pure web2 and doesn’t use any web3 creds like doing txns n all. just you have sign with your wallet and do a 3d facescan. | As stated above, an Identity Holder carries their personal data, in the form of VC, within their wallet. At its core, the wallet stores the private key of a user, fetch VCs from the Issuer, and create zero-knowledge proofs to be presented to the Verifier" | KYC, helps dapps to airdrop to unique users, ensuring unique users to get access to broader polygon ecosystem. | Uses MATIC (Which is now POL) as part of the Polygon ecosystem, though Polygon ID itself does not have a specific token. | There’s nothing unique in terms of proving unique human, just that they store the info using zkp’s can be called unique. | ZKP, Verifiable Credentials, DID, zk-Rollups. | | Reclaim Protocol | Creates verifiable, self-sovereign identities across web2 and web3.
For example, you could ask the user to login into their bank and prove their bank balance. You could ask your user to login into Uber and prove that they've taken more than 50 rides this year. All of this happens without compromising security and without needing any change on the bank's or Uber's side. Not just Banks and Uber, you can connect to any website on the internet. | Ask users to import their user profile and activity from any website, verify that a particular user has kyc’ed on given websites and apps.
Also, they created digital signatures using zkps of users identity and reputation on any website.
These digital signatures are computed completely on the client side. | Data points from both web2 and web3.
for eg, web2 data points can be account information, activity records, social media profile data, subscription/service data like netflix, etc.
web3 data points can be wallet activity, balances in each chain, txn history, nft ownership, etc.
But we can say it mostly leans towards web2 data since its primary focus is verifying data from traditional services (banks, social platforms, apps). | It is privacy preserving, creates digital signatures and zkp that allows users to generate digital attestations of their user data on the web.
for eg: Users can share parts of their data that they want to, without giving away sensitive information. For example, a user can show that they're a good driver without giving away their license plate number. | Proof of ownership and access control across websites.
Anyone can use reclaim sdk, you can ask your users to prove certain identity and reputation they have on other websites. | No native token. | Imagine you want to show your friend something you got from a website, like a toy. But instead of just saying, "I got this toy," you ask a special group of helpers (proxies) to sign a paper that proves you really got the toy from that website.
So, when you show your friend the toy, you also show them the signed paper to prove you’re telling the truth. That way, everyone knows you really got the toy, and you're not making it up!
Reclaim Protocol is like those helpers, making sure what you get from a website (like your bank balance) is real and verifiable. | Verifiable credentials, DID, Zero-Knowledge Proofs. | | Aspecta ID | User can add labels such as github to reveal builder insights, stackoverflow and leetcode to see activity in open source discussions, dev.to and hashnode profiles to check if you are a writer. | There is no proper kyc to prove you are human, you can add labels and stamps to prove you are human plus making your profile active by sharing achievements like frontend master - which is contributing to open source frontend projects, total commits you did, pr reviews and issue raised, etc.
Its like an linkedin profile where you can add tags if you are developer or not, which skills you have, you also get followers on the basis of how your profile looks, likes, etc.
You can also contact profiles you like via mail which linkedin does if you’re not a connection. | Most of it is web2 with majorly dev based, just one part makes the difference is that the profile connected with a wallet address.
So basically linkedin with solana or evm whatever you wanna say. | There’s no need for storage, also user can do selective disclosure and uses zkp so basically they are privacy preserving.
They just read the data when user connects their profile in particular sites.
In their docs, this is written:
Taking GitHub as an example, with user authorization, Aspecta will count the number of a user's private commits as an endorsement for the user, but will never read or seek authorization to access the content of private repositories. | create an ecosystem of privacy focused developers and creators where they can share the data they only choose to. | No token. | Cross-platform, professional identity management bridging web2 and web3 together. | Verifiable credentials, DID, decentralized storage, zk-SNARKs. | | ‣
Humanity Protocol | Uses palm recognition to prove proof of humanity.
They claim themselves as evm compatible layer-2 blockchain, where any entity can create a wallet and use their wallet addresses as digital identifiers (DID) and hold verifiable credentials (VC) that prove their uniqueness and other claims. | Palm scan using decentralized storage, and zero-knowledge proofs. | Mostly its human touch, doing palm print recognition, and palm vein recognition.
| Palm scans are not stored by Humanity Protocol or any centralized entity. They are distributed across multiple zkProofers that act as nodes that support the protocol. By capturing palm features in both visible and infrared light, the system makes spoofing nearly impossible. | Cost effective kyc - traditional kyc process is costly and often requires compliance while handling data.
fairdrops - fighting industry sybil
