Ludo. Reputation platform of Web3

Ludo aimed to build a reputation layer for Web3. In a space filled with wallets, NFTs and tokens, users lacked an easy way to gauge trust. The goal was to make reputation open, portable and valuable across different platforms.

The team aimed to:

• Create a cross-chain reputation score that updates in real time.
• Provide users and projects with a trust signal that goes beyond token prices.
• Offer tools for curators and builders to connect with reliable audiences.

Ludo needed a partner experienced in high-load, real-time Web3 platforms. Pharos Production had the background in blockchain, DeFi and large-scale data processing to bring this idea to life. That expertise made us the right fit to deliver a fast, scalable reputation system for the Web3 ecosystem.

The backend uses Java with Spring Boot to provide a reliable foundation for APIs and reputation logic. Apache Kafka handles event streaming, while Apache Flink processes large amounts of real-time blockchain data. This configuration ensures reputation scores are fast, accurate and always current.

The platform features a modern React frontend designed for both web and browser extensions. A Telegram mini-app was added to make reputation scores accessible on the go, meeting users where they already interact in Web3.

Apache Cassandra manages user and reputation data at scale, while Delta Lake organizes historical data for analytics. Apache Pinot powers real-time dashboards and APIs for curators and builders. Everything runs in Kubernetes with Istio for traffic management, deployed on AWS to ensure scalability and reliability.

Ludo aggregates data from multiple blockchains and updates reputation scores in real time. This provides users and projects with a clear, current indicator of trust.

Reputation insights can be accessed across various touchpoints. Users can view their profiles on the web, via a browser extension, or directly within a Telegram mini-app.

Reputation is represented by soulbound NFTs that can’t be transferred or sold, keeping it authentic. Curators use Ludo to build trusted lists, while builders utilize public APIs to incorporate reputation data into their own products.

Ludo developed a new method for measuring trust across blockchains. Reputation scores now help users quickly identify trustworthy projects and communities.

Curators use Ludo to build trusted lists of wallets and collections. Builders incorporate the reputation APIs into their apps, while projects use them to demonstrate credibility.

With its event-driven architecture, Ludo processes blockchain data at scale without delays. Every reputation score is transparent, traceable and updated in real time.
