[0002] In the development of modern communication technology, peer-to-peer instant messaging has become an important application field; traditional instant messaging technology mainly relies on centralized servers for information transmission. Although this model can achieve instant messaging between large-scale users, it also has obvious disadvantages, such as single point failure, high server pressure and data privacy issues. With the development of blockchain technology, decentralized peer-to-peer communication has become an emerging trend. The use of blockchain's distributed ledger technology can effectively solve many problems in traditional centralized communication. Blockchain technology is essentially a decentralized database, and each node can store and verify data. This feature makes blockchain very important in ensuring It has significant advantages in data security and transparency; however, how to apply blockchain technology to instant messaging and achieve efficient and stable point-to-point communication is still a technical problem that needs to be solved urgently; in point-to-point communication, the transmission quality and transmission time of the signal are two important factors that affect the communication effect; the signal-to-noise ratio is an important indicator to measure the quality of signal transmission. The higher the signal-to-noise ratio, the less noise interference the signal is subject to during transmission, and the higher the communication quality; therefore, in point-to-point communication, how to test and obtain the signal-to-noise ratio of the signal transmitted between devices, and then select the best signal transmission path, is the key to ensure the quality of communication; transmission time is another important factor affecting point-to-point communication. In the actual communication process, the transmission time of the signal between devices will be affected by many factors, such as the signal receiving range of the device, the choice of transmission path, etc.; in order to ensure the immediacy of communication, the transmission time of the signal between devices must be tested and optimized, so as to select the best transmission path and achieve fast and stable communication.

[0003] In response to the above problems, the present invention proposes an intelligent blockchain point-to-point instant messaging method and system, which obtains the signal-to-noise ratio and transmission time between devices, selects the optimal signal transmission path, and makes dynamic adjustments during the signal transmission process to ensure the quality and efficiency of communication.
