Welcome to BRAIN, a pioneering Blockchain-based Reliable AI Network that aims to revolutionize the way AI models are trained and executed, ensuring transparency, reliability, and efficiency.

BRAIN offers a groundbreaking solution that enhances decentralized AI by merging AI with blockchain for secure, transparent, and scalable AI applications, overcoming challenges with large-scale models and ensuring high throughput and reliability even in the presence of Byzantine nodes.

• Two-Phase Transaction Execution: Enhances blockchain performance by allowing pipelining among inference/training transactions and regular transactions.
• Asynchronous Aggregator-Free Federated Learning: Implements an innovative asynchronous federated learning algorithm that does not require a central aggregator, ensuring privacy and scalability.
• Scalable Verification: Employs a verifiable randomly selected committee for scalable verification of inference and training processes, achieving consensus through smart contracts.
