Abstract: 【Purpose/significance】To improve the effect of scientific research information sharing, research the construction and opera⁃tion mechanism of scientific research information sharing platform based on blockchain technology.【Method/process】First, use the blockchain co accounting technology to complete the sharing of scientific research information, and then use the scientific research in⁃formation decryption center to provide public and private keys, decrypt and package scientific research information, and improve the security of scientific research information sharing. Second, use the ITPBFT consensus mechanism to make the scientific research infor⁃mation of each node in the blockchain reach a consensus. Then use the blockchain technology to build a scientific research informa⁃tion sharing platform, and finally, through open access, integrated sharing in four aspects of service connection and performance evalu⁃ation, design the operation mechanism of scientific research information sharing platform service mode, and improve the platform ser⁃vice effect.【Result/conclusion】The scientific research information sharing platform based on blockchain technology can effectively share scientific research information, has strong malicious attack resistance and high security of scientific research information shar⁃ing, and the sharing service effect is better【Innovation/limitation】The use of blockchain technology to achieve scientific research in⁃formation sharing, improve the comprehensive utilization rate of scientific research information, and scientific research information sharing platform is of great significance for scientific and technological innovation.
