Abstract:
(EN) Implementations of the present specification disclose a blockchain data processing method, apparatus, device, and system. In an implementation, a state transition message of a smart contract is received at a plurality of blockchain nodes of a blockchain system, where the state transition message comprises signature data of at least one state participant of the smart contract. At a blockchain node of the plurality of blockchain nodes of the blockchain system, the signature data is verified by using at least one public key of the at least one state participant. A smart contract state in the state transition message is confirmed if signature data of the at least one state participant of the smart contract is verified, where a number of the at least one state participant is pre-determined in the smart contract.
(FR) Des modes de réalisation de la présente invention concernent un procédé, un appareil, un dispositif et un système de traitement de données de chaîne de blocs. Dans un mode de réalisation, un message de transition d'état d'un contrat intelligent est reçu au niveau d'une pluralité de nœuds de chaîne de blocs d'un système de chaînes de blocs, le message de transition d'état comprenant des données de signature d'au moins un participant d'état du contrat intelligent. Au niveau d'un nœud de chaîne de blocs de la pluralité des nœuds de chaîne de blocs du système de chaînes de blocs, les données de signature sont vérifiées en utilisant au moins une clé publique du ou des participants d'état. Un état de contrat intelligent dans le message de transition d'état est confirmé si les données de signature du ou des participants d'état du contrat intelligent sont vérifiées, le nombre des participants d'état étant prédéfini dans le contrat intelligent.
