Embodiment Construction
[0030] To evaluate the system performance, a prototype system was built. This experiment shows the performance of the core modules of the system, mainly including: indexing performance, transaction blockchain network performance and security computing performance.
[0031] 1) Description of the experimental environment
[0032] The experiment is carried out on 5 ubuntu cloud servers, and the configuration of each server is as follows: the processor adopts Intel (R) Xeon(R) 2.0G, dual CPU; the memory is 2GB; the operation adopts Ubuntu 14.04.5LTS server, and the kernel version number is 4.4 .0-31-generic. The five servers are respectively named node1, node2, ..., node5, among which node4 and node5 store original data sets, which are both data providers and participants in secure computing. Any node in node1-3 can be used as the data demander. All nodes are candidates for block consensus.
[0033] Software implementation relies on open source software architecture, in which ...
