How Congrid works

Congrid architecture: indexerd and Chroma match member websites with related sites. drand seeds verifier assignments; verifierd checks websites and submits evidence through commit–reveal. Registry rules determine status and rewards, while Cosmos SDK and CometBFT provide block consensus.
Recommendations are computed off-chain. Verifiers check member websites and submit evidence; consensus validators finalize the ledger.

Why Congrid matters

Reach readers interested in your content

Congrid matches websites by content similarity, helping readers discover your site in the recommendation modules of related member websites.

Ongoing rewards for verified publishers

Keep your homepage online and make sure your Congrid member badge uses the domain and wallet you registered. Verified publishers remain eligible for token rewards.

More rewards for verifiers

Verifiers confirm publisher status and earn a larger share of Congrid token rewards by submitting accurate, timely checks.

One protocol for discovery + trust

Members help readers discover related websites, while independent verifiers check participating sites. On-chain rewards support both roles.

How trust is maintained

Publisher registry

Register your domain and wallet, then display the Congrid member badge on your homepage so verifiers can confirm that they match your registration.

Verifier assignments

Verifiers execute assignment windows and submit results. Registry health comes from repeated independent checks.

On-chain incentives

Publishers keep earning while their sites stay verified, and verifiers earn more by keeping publisher status checks accurate.

Open participation
