Abstract
(EN) A method and apparatus for aggregation calculation in a blockchain-type ledger, and a device. The method comprises: when aggregation calculation is performed in a blockchain-type ledger, performing iteration processing on a calculation target; each time iteration calculation is performed, performing integrity verification on a currently used data record; and after verification is passed, performing aggregation calculation, and if verification fails, terminating aggregation calculation at any time.
(FR) L'invention concerne un procédé et un appareil de calcul d'agrégation dans un registre de chaîne de blocs, et un dispositif. Le procédé comprend les étapes consistant à : lorsqu'un calcul d'agrégation est effectué dans un registre de chaîne de blocs, effectuer un traitement d'itération sur une cible de calcul ; chaque fois qu'une itération de calcul est effectuée, effectuer une vérification d'intégrité sur un enregistrement de données actuellement utilisé ; et après que la vérification a réussi, effectuer le calcul d'agrégation, et si la vérification échoue, mettre fin au calcul d'agrégation à tout moment.
(ZH) 一种块链式账本中的聚合计算方法、装置及设备。所述方法包括：在块链式账本中进行聚合计算时，对计算目标进行迭代处理，每次迭代计算时，对当前所采用的数据记录进行完整性验证，验证通过之后再进行聚合计算，若验证失败则随时终止聚合计算。
