Cross-chain interoperability remains one of the most critical challenges in blockchain technology, particularly within decentralized finance (DeFi) ecosystems. Current bridge protocols suffer from security vulnerabilities, high transaction costs, and limited scalability. This paper proposes a novel Consensus-Based Bridge Protocol (CBBP) that leverages multi-signature validation combined with zero-knowledge proofs to enable secure, efficient, and scalable cross-chain asset transfers. Our experimental results demonstrate a 43% reduction in transaction costs and a 67% improvement in security metrics compared to existing bridge solutions. The protocol has been tested across Ethereum, Polygon, and Binance Smart Chain networks, showing promising results for real-world implementation.

The block chain is recently introduced and revolutionizing the digital world bringing a new perspective to security, resiliency, and efficiency of system. The focus of the study is to understand how the blocks are created in the block chain and how the decentralized shared economy applications that allow the people to secure their things that was previously unattainable to create more wealth.
