Reclaim Protocol lets users generate credentials without leaking private information. One thing we think about a lot is how to we make sure our users don’t get doxxed. Let’s define the problem more concretely. Say you, as a user, generated certain credentials for on-chain use. You created a credential from your Uber account, your Tinder account, your Doordash account, your Tax Records and so on. Let us assume that given enough data points on chain, it might be possible to triangulate the particular you, the user, that is interacting with a certain smart contract....
Reclaim Protocol RFPs
If you are building any of these, you should definitely consider applying for a grant on Questbook. Finance Discounts & Deals based on shopping history Shopping history has historically been proprietary information owned by the platform where the user did the shopping, like Amazon, Shopify, Ebay. However new applications can be built which poaches customers from other platforms by giving discounts and deals to power shoppers - by using reclaim Protocol to import shopping history....
RFP - AI friendly ZK Captcha
Madhavan (Mads) Malolan Which side is up? Captchas are getting so hard that only AIs will be able to solve it. The key premise of this post is that it is getting increasingly important for AI agents to be able to access web products on behalf of the user. Captchas are an antipattern. They are not any good at keeping AI bots out anyway, at the same time they’re detrimental to productivity....
RFP: Decentralized Oracles & Data Guilds
Chainlink, but for long tail data sources. Data Guilds A data guild is a DAO setup on chain to source certain data feeds. For example, there may be a Data Guild for Weather in Mumbai, another for NBA scores etc. In this DAO, there are two key participants. Subscribers - who use the data feeds Oracles - who provide the data onchain Coins Each Data Guild has its own coin. This coin governs the data feeds coming on chain....
Appclip and Instantapp
Most people assume that to generate proofs using Reclaim Protocol, you need to install a chrome extension or a mobile app. This is true for most zk-tls solutions out there, including Reclaim Protocol until early 2024. Not any more. All that you need is a mobile phone. You don’t need to install anything on it. You just scan a QR code, and the Reclaim Protocol proof generation starts. Check out the Demo Appclips and InstantApps Appclips and InstantApps are mini apps that can be opened on iOS and Android respectively without having to install an app....
Login Using Anything
Sign in with Google is all over the internet, but have you seen a Sign in with Uber, Sign in with Fortnite, or Sign in with Amazon? No - that’s because these websites don’t expose an OAuth API. Skip if you already know what OAuth is. OAuth API is an API that, for example, Google exposes. This OAuth API has two steps. The first step is to retrieve the Auth Token....

Duplication Counting : Ensuring one proof is used only once, without doxxing the user
Introduction For many applications, it will be critical that multiple users are not able to claim the same credential, at least without being detected. For example, suppose a user proves they own some funds in a certain bank account, and then later shares that their banking login to another user who then proves the same credential. An application that requires users t have some minimum collateral will need to be able to detect if the same bank account is being claimed multiple times....
Honeypot Mechanism for additional protocol security
To discourage attestors from certifying false claims, we want to make this dishonest behavior as financially risky as possible. While the Reporting Mechanism already provides some such financial risk, even more risk can be added through the Honeypot Mechanism. This mechanism which allows users to prepare trap claims, and attestors who accept a bribe to certify a trap claim will get caught in the trap. Trapped attestors are then charged a penalty, and the penalty is given to the user who trapped them as a reward....
Onchain Attestations
Reclaim Protocol is available in any format the developer wants to consume proofs on chain. Below are adapters that are used by many dapps. Check out the demo video or live demo PolygonID, on Polygon Reclaim Proofs can be created using PolygonID. It can also be stored securely for later use on the PolygonID Wallet. EAS, on Ethereum, Optimism and Arbitrum Ethereum Attestation Service is a simple attestation framework. One can consume and publish Reclaim Proofs as EAS Attestations....
