The present invention discloses a tree-shaped blockchain generation method and device for improving the transaction throughput of blockchain. The blockchain structure includes a global chain and a contract chain. The global chain is composed of blocks containing non-contract call transactions initiated by users, and the contract chain is composed of blocks containing contract call transactions initiated by users; the block where the contract deployment transaction is located is selected as the fork point; the transactions are packaged into different blocks according to the transaction type; when each block is generated, the global chain or contract chain identifier and the fork identifier are written, and the latest block of the corresponding chain is found as the parent block through the chain identifier and the fork identifier; the above operations are cycled to finally form a tree-shaped blockchain. Based on the tree-shaped blockchain structure, when the blockchain nodes reach a transaction consensus, the transaction verification for the global chain and the contract chain can be processed in parallel. The method of the present invention can firstly realize the effective isolation and classification management of various types of business chain data, and secondly, effectively improve the transaction processing efficiency and improve the transaction throughput.
