Sentinel
Real-time blockchain mempool monitoring for accurate transaction analysis and insights.
About
Why are you participating for Based Africa? We're participating in Base Africa to use blockchain technology to empower Africa's tech ecosystem. This hackathon is a chance to create solutions with real impact on the local economy. We're passionate about using decentralized tech to solve challenges in emerging markets like Africa. We want to contribute to the continent's growing tech potential and drive positive change.
How it's made
What challenges are you focusing on? We are tackling the problem of limited blockchain data access in Africa. Many developers and businesses struggle to monitor and analyze blockchain transactions effectively. Our project creates a blockchain indexer that provides real-time, accurate transaction data. This tool will help users track and analyze blockchain activity easily, supporting innovation and wider blockchain adoption in the region. How does your submission address this challenge? Our project is a blockchain indexer that monitors real-time transaction data on the blockchain. It tracks key details like gas fees, transaction times, and confirmation status. This tool addresses the challenge of data transparency by giving users easy access to accurate blockchain information. The potential impact is significant: 1. Developers can build better decentralized apps with this data. 2. Businesses can make informed decisions about blockchain usage. 3. Users can track their transactions more easily, building trust in the system. By making blockchain data more accessible, we're supporting innovation and wider adoption of this technology in Africa. Challenges we ran into Technical challenges we faced: 1. Handling real-time Ethereum data at scale 2. Ensuring data accuracy with changing gas fees and confirmation times Solution: We used async Rust with tokio and sqlx for better performance. We also added error handling and retry mechanisms for improved reliability. Non-technical challenges we faced: 1. Finding reliable node providers 2. Maintaining stable network connections Solution: We partnered with trusted blockchain API providers and used decentralized infrastructure to ensure consistent data access.
