| With the rapid development of Internet in the world of financial, the digital currency come into being because Bitcoin, making the model of financial transactions based on cryptography change to trust based model, the thought of the no central transaction places are widely used in other areas. At the same time, the digital currency is used by people in many countries around the world, and influencing and changing people’s payment, greatly promoted the development of changes in the real economy and financial system. Recently, People’s Bank of China decided to issue the digital currency by themselves in order to promoting the development of domestic economy, Thus, exploration and research in computer field digital currency system has positive practical significance.At present, a variety of digital currency system as the representative of bitcoin in the peer-to-peer transmission performance, transaction verification efficiency and other functions still need to be improved. Therefore, our project group will develop a new digital currency system, so that the node message transmission function, block chain verification efficiency has been greatly improved. The main work of this paper is design and implementation of a new digital currency system P2P message-passing mechanism. On the study and analysis of the bitcoin in P2P network transmission mechanism, in this paper will design P2P message-passing mechanism based on the index server, as the verification node system by the index server, and the verification node connect with ordinary nodes, forming a P2P network and realizes fast peer to peer communication. For the system to provide efficient underlying network services. New system is implemented in Linux system and the test is based on the P2P network, node A and node B can communicate with each other normally. The result show that the P2P message-passing mechanism based on the index server can transmit the message effectively to other peer nodes in the network. |
