Protect Your Community From Bots and Bad Actors.

Without storing your users’ personal information.

Gitcoin Passport is a simple yet powerful sybil resistance solution that helps you gate access to your project or community in a privacy-preserving way. It's also a tool for your users to collect “stamps” that prove their humanity and build their decentralized identity.

Passport for Communities

Gitcoin Passport was designed to make sybil resistance easy. As the leading open-source sybil defense protocol for the decentralized web, we believe privacy-preserving identity verification is a public good.

Inherit Gitcoin-Grade Protection

Integrate Sybil defense for your community with just a few lines of code, based on years of institutional learning through work protecting the Gitcoin Grants program.

Preserve Your Users' Privacy

Verify your potential users and community members through open web standards like DID and VC without having to store personally identifiable information.

Customize How You Gate Your Project

Stick with Gitcoin’s battle-tested defaults or verify accounts according to your own criteria of who should be given access to your project.

Passport for Internet Citizens

Passport enables you to easily prove your humanity and build a decentralized identity, all in one place. And at each step of the way, you only disclose what you want.

Online identifiers (both web2 and web3), such as Twitter, Google, BrightID, and Proof of Humanity make up what we call ‘stamps.’ These stamps are all aggregated into Passport’s platform to build your unique identity score. Connected apps like Gitcoin Grants validate your online identity by referencing this score.

The higher your score the better, and you can increase your score by verifying more stamps. The best part is, as you verify more stamps, you make the system more sybil resistant for all others by raising the (forgery) bar.

Already on its way to becoming the go-to solution for projects to protect their communities, Passport is the identity solution you need to access the best and most trustworthy experiences in web3.

Why Passport is a gamechanger for both web3 projects and users

Proof of Humanity and other proof-of-personhood systems let users prove that they are unique humans, which is useful in many applications including airdrops and governance. Each of these applications are useful individually. But what makes them truly powerful is how well they compose with each other. The network effects of these different services [through a meta-aggregator like Passport] combine to create an ecosystem that provides some very powerful options for users and applications. An Ethereum-based Twitter alternative (eg. Farcaster) could use POAPs and other proofs of on-chain activity to create a "verification" feature that does not require conventional KYC, allowing anons to participate. Such platforms could create rooms that are gated to members of a particular community - or hybrid approaches where only community members can speak but anyone can listen.

Inherit Gitcoin-Grade Sybil Defense Today

One thing we have learned from years of defending the Gitcoin Grants program is this:
 
Sybil defense is complicated and resource intensive.
 
Yet it is essential for any web3 project that hopes to have longevity, because users will not stick around if your project is filled with scammers.
 
As we developed years of in-house expertise in sybil defense, we saw a responsibility to help other web3 projects protect their communities from attackers.
 
Because we believe that private identity verification is a public good, we decided to turn Passport into its own product.


Let us help you level up your project so that it is just for real people who care about your project, not bots and bad actors. There are just a few steps to get started:

1. Onboard

Customize your community's Passport front-end or use Gitcoin's pre-built interface.

2. Select credentials

Choose the stamps users need to collect to sign up to your app or get access to your community.

3. Assign weights

Assign a weight to each stamp a user can provide as proof of their humanity and online reputation.

4. Verify

Passport's algorithm automatically screens out users without the right stamps.

What data is stored in my Passport?

The only information in your passport is the Decentralized Identifier (DID) associated with your Ethereum address and the Verifiable Credentials (VCs) issued for each service you connect to your passport. Verifiable credentials can be issued based on data from both web2 and web3 apps. 
 
You can inspect the data yourself in the Gitcoin Passport by clicking the </> Passport JSON button in the upper right of the Passport dashboard.

Who can read my data?

The data on Ceramic is readable to anyone, but can only be written by you. Again, readable data does not include any personally identifiable information.
 
Knowing your Ethereum address, or your DID, or your Ceramic Stream ID the data can be fetched from Ceramic, and your Passport can be read.

Who can write into my Passport?

Only you can write into your Passport. This is important: you grant access to apps that you visit when you sign a message with your wallet granting access to your stream (like when you connect to the Gitcoin Passport app). Your Passport requires your unique wallet signature to allow write operations, and only apps that want to write to your passport need to request you to sign those messages.
