The invention discloses a method and system for redundant scheduling of blockchain transactions. The method includes: redundant nodes in an organization receive a batch of transactions, calculate task management scheduling requests, and complete data reading; each redundant node manages the scheduling requests according to the tasks , adopt a variety of different transaction scheduling strategies to pre-execute transactions and package them to form blocks, and return the execution result time; according to the execution result time, based on the shortest time judgment condition, select the optimal scheduling strategy; in the consensus verification stage, the consensus verification node The block is verified using the optimal scheduling strategy. It makes full use of the redundant computing power of the distributed storage and computing separation architecture of the blockchain to realize the optimal scheduling strategy selection, which can accelerate the overall processing performance of blockchain transactions. Based on the distributed storage and calculation separation architecture, the storage and calculation separation can be realized, and the ledger storage resources and computing resources of each node in the blockchain network can be completely decoupled. The scheduling strategy selection is more efficient, and the optimal scheduling strategy has higher transaction scheduling execution efficiency.
