| description | The invention provides an electronic contract signature method and device, electronic equipment and a system, and relates to the technical field of block chains. The method comprises the steps that an SIM card configured in terminal equipment serving as a block chain node determines a target contract type to which a contract to be signed belongs; performing hash operation on the target contract type to obtain a hash value of the target contract type; the hash value of the target contract type is sent to the terminal equipment where the target contract type is located, and the hash value is used for the terminal equipment to obtain certificate summary information corresponding to the hash value from the block chain network; receiving certificate summary information sent by the terminal equipment, and obtaining a target electronic signature certificate corresponding to the certificate summary information from the SIM card; and signing the to-be-signed contract based on the target electronic signature certificat |
