Title
(EN) Aggregation calculation method, device and apparatus in block chain type account book
(ZH) 一种块链式账本中的聚合计算方法、装置及设备
Abstract
(EN) The invention discloses an aggregation calculation method, device and apparatus in a block chain type account book. When aggregation calculation is carried out in the block chain type account book, iterative processing is carried out on a calculation target, integrity verification is carried out on a currently adopted data record each time iterative calculation is carried out, aggregation calculation is carried out after verification is passed, and if verification fails, aggregation calculation is terminated at any time.
(ZH) 公开了一种块链式账本中的聚合计算方法、装置及设备。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。
