Ethereum state data storage optimization method, Ethereum system and storage medium
Disclosed are an Ethereum state data storage optimization method, an Ethereum state data storage optimization system, and an Ethereum system. The method includes: using an MPT tree structure to store Ethereum state data; and compressing a height of an MPT tree, so as to reduce the number of times of disk io. By increasing capacity of a branch node, optimization in a horizontal direction can be performed to the MPT tree of Ethereum state data; by compressing the height of the MPT tree of the Ethereum state data on a single prefix path, optimization in a vertical direction can be performed to the MPT tree of the Ethereum state data; and by selecting and arranging different key lengths according to a data type, layers of the MPT tree can be effectively reduced, so that the purpose of reducing the number of times of disk io can be achieved.
