The invention provides a blockchain intelligent contract realization method and device, computer equipment and a storage medium, and the method comprises the steps: a computing node in a blockchain network receives a computing request initiated by a computing initiator; in response to the calculation request, the computing node executes an off-chain calculation operation on the calculation contentcorresponding to the calculation request to obtain a calculation result and verification data; and the computing node initiates a chaining request for chaining and storing the computing result and the check data to the blockchain network, the block chain network verifies whether the computing result and the check data are correct or not in response to the chaining request, and under the conditionthat the computing result and the check data are verified to be correct, the computing result and the check data are chained and stored. According to the method, when the complex intelligent contractis deployed, the blockchain system performance can be effectively improved, the system expandability is improved, and the calculation correctness is improved.
