Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for smart contract and blockchain data storage. One of the methods includes determining that data stored in a cache storage satisfies a predetermined condition; adding a blockchain address of a second smart contract to a configuration file, wherein the configuration file includes a plurality of addresses corresponding to a plurality of smart contracts stored on a blockchain; and invoking a virtual machine to execute the configuration file, wherein execution of the configuration file initiates a consensus algorithm to generate the second smart contract at the blockchain address and a corresponding smart contract pool for storing at least a portion of the data on the blockchain, and wherein the smart contract pool is a data structure to be stored on the blockchain.
