Design and implementation of blockchain-based digital advertising media promotion system

In recent years, the rapid development of the Internet digital advertising (IDA) market has brought many issues. Low-quality advertisements (ADs) have caused significant troubles for Internet users, and the “AD fraud” has plunged the IDA ecosystem into a crisis of trust. The blockchain’s trusted computing model provides new ideas for solving the above problems. In this paper, we designed and implemented a blockchain-based digital advertising media system (B 2 DAM), where the Hyperledger is used as the implementation platform. Our B 2 DAM system integrates distributed ledger, multi-chain, smart contracts, and consensus mechanisms to ensure decentralization and multi-party maintenance of immutable data. We implemented business logic in smart contracts and Hyperledger SDK. The experiments show the transaction throughput can reach 550 tps and the system can meet the application requirements.
