Web3.0 is the next generation of the internet, characterized by the integration of blockchain technology and decentralized systems. A transaction processing system in this context refers to the infrastructure that facilitates the execution and validation of transactions on a blockchain network.This paper presents a novel transaction processing system for Web3.0 that utilizes sharding, a technique for horizontally partitioning data across multiple nodes, to improve scalability and reduce the burden on individual nodes. Additionally, the system employs a consensus mechanism based on proof of stake, which allows for faster and more efficient validation of transactions. The proposed system has been tested on a simulated network and has shown to be able to process a significantly higher number of transactions per second compared to existing systems while maintaining a high level of security and decentralization.Overall, the proposed web3.0 transaction processing system offers an improved scalability, security, and decentralization that enables the Web3.0 to process a significantly higher number of transactions per second.
