[B4] - Karma3 Trustmaze - On-chain Rankings and Reputation using attestations and Eigentrust 🏅

Building a trust and reputation protocol using the eigentrust algorithm using on-chain attestations.

Challenges

Integrate Lens

Pool 10,000 USDC

Reason for applying

We used the Lens Protocol data to create a Ranking and Recommendation system.

Most Useful Web3 Tool

Ranked 2,500 ETH

Reason for applying

On-chain ranking and reputation Infrastructure.

Best Lens app

Ranked 15,000 USDC

Reason for applying

We used the Lens Protocol data to create a Ranking and Recommendation system.

Best Use of Polygon

Ranked 10,000 ETH

Reason for applying

We have used Lens protocol Data to create an example of on-chain wallet reputation on Polygon using an attestation contract. The data is on-chain, the EigenTrust computation of reputation is verifiable. This infrastructure can be used by any developer on Polygon for on-chain reputation.

#BUIDLathon 2023 Infrastructure + Scalability

Pool 15,000 USDC

Reason for applying

We are building an infrastructure for on-chain reputation using attestations as the data layer and EigenTrust as the compute layer. This protocol can be used as a reputation infrastructure by a variety of use cases.

Create a Developer Tool for the AttestationStation

Ranked 9,896 USDC

Reason for applying

We have used EIgenTrust computation as a useful tool for on-chain reputation using Attestation Station Contract.

Create an AttestationStation App

Pool 11,573.6 USDC

Reason for applying

We've created a Web3 Social Ranking Attestation for the Top 100 and Lowest 100 ranked profiles. There is a front-end for any app or developer to visualize these attestations.

Create an AttestationStation Visualization

Pool 3,000 USDC

Reason for applying

Using our front-end you can easily visualize the attestations issued to the top 100 and lowest 100 Lens profiles, ranked using EigenTrust.

Vision

Enabling an Open Ranking and Reputation system using on-chain attestations and EigenTrust.

Why

Attestations are manifestations of trust in peer-to-peer decentralized environments.

We have used EigenTrust to deliver high-quality trust scores and rankings for dApps. EigenTrust enables a verifiable algorithmic computation of any peer-to-peer attestation of on-chain data.

This will be a key pillar to enable on-chain reputation in a variety of use-cases in web3.

What have we built

Smart Contract - Attestation contract to record attestations and metadata (aka schema) about attestations. (Inspired by Optimism’s Attestation Station Contract with edits)
Publisher for Attestation Schema - Created a Global EigenTrust ranking score of Top 100 and Lowest 100 Lens protocol profiles (Polygon) using on-chain social graph data to publish in this schema.
Front-end - Displays attestations issued to the top 100 and lowest 100 ranked profiles that other projects can consume and build upon. It reads and visualizes transactions from smart contract.
