Title
(EN) Data storage method and system based on plurality of block chain networks
(ZH) 一种基于多个区块链网络的数据存证方法及系统
Abstract
(EN)
The invention discloses a data storage method and system based on a plurality of block chain networks. The data stored by the block chains of the at least two first-class block chain networks are mapped to the block chain of the second-class block chain network. Specifically, for any first type of block chain network, the first type of block chain network sends the transaction hash of each constructed first type of storage transaction to a second type of block chain network, and the second type of block chain network constructs a second type of storage transaction based on the received transaction hash and writes the second type of storage transaction into a block chain of the second type of storage transaction. Thus, the transaction Hash of the first type of evidence storage transactionsstored on the block chains of the first type of block chain networks is further packaged into the second type of evidence storage transactions, and the second type of evidence storage transactions aregathered on the block chains of the second type of block chain networks.

公开了一种基于多个区块链网络的数据存证方法及系统。将至少两个第一类区块链网络的区块链所存证的数据映射到第二类区块链网络的区块链中。具体地,针对任一第一类区块链网络,该第一类区块链网络将构建的每个第一类存证交易的交易哈希发送给第二类区块链网络,由第二类区块链网络基于接收到的交易哈希构建第二类存证交易并写入自身的区块链。如此,相当于将各第一类区块链网络的区块链上所存储的第一类存证交易的交易哈希进一步封装为第二类存证交易,汇总于第二类区块链网络的区块链上。
