Bis: A Novel Blockchain Based Bank-Tax Interaction System In Smart City

When banks loan to small and micro enterprises, they are faced with higher credit costs and difficulties in controlling risks. Blockchain provides a distributed infrastructure for business connectivity across organizations. Blockchain is a consensus, traceable, tamper-proof, final shared data ledger. Blockchain not only improves the efficiency of data connections, but also promotes the credible flow of data. In this background, we propose Bis: a Novel Blockchain based Bank-tax interaction system in smart city. We have designed the total scheme, and the tax bureau can use blockchain to build bank-tax interactive system. Most commercial banks can obtain the enterprises tax information in an efficient and safe way through multi-channels technology of Blockchain. We carried out system development and experiments to prove that our Bis system can solve enterprise tax data sharing and business connection problems across enterprises, tax bureau and banks.
