Abstract: BlockBazaar is this new decentralized marketplace thing that mixes NFT trading with regular e-commerce stuff. It runs on Ethereum smart contracts and has live auctions that work across different devices. You log in using MetaMask wallets, which keeps things pretty secure from the start. Access levels depend on your role in the system, you know how that goes.The security side uses hardened smart contract patterns to block common attacks like reentrancy issues or front- running scams. Every transaction gets recorded publicly through blockchain explorers, so there's full visibility into what's happening. The whole setup cuts out a lot of traditional cloud services while keeping user privacy tight. Testing shows these decentralized platforms can actually handle enterprise-grade security requirements without slowing things down. Response times stay quick even during peak usage, which matters for real-world shopping scenarios. Users get familiar interfaces that don't sacrifice blockchain's core benefits like permanent records and trustless transactions. The key takeaway here is that hybrid systems can bridge Web3 tech with conventional e-commerce needs effectively. Performance metrics match centralized competitors while maintaining cryptographic proof of ownership for digital assets.
