Abstract

一种不同许可链之间的跨链交易方法,约定不同用户在不同的许可链上有加密资产,且他们在另一条许可链上各自开设账户,则不同用户可以通过该许可链进行资产交易。基于所述方法,不同的许可链之间信息不直接交互;通过区块链跨链技术,将不同许可链的信息映射到同一条许可链上,使得这些信息可以在同一许可链上进行交互,并保证结果的一致性。

Description

不同许可链之间的跨链交易 技术领域
本发明涉及区块链技术领域,尤其是区块链之间的跨链技术。
背景技术
区块链技术日益成熟,不同企业由于其交易功能、隐私保护、生态发展等需求,比起对所有人开放、任何人都可以参与的公有链,更加倾向于选择对特定的个人或团体开放的许可链。跨链技术可以把许可链从分散单独的信息孤岛中拯救出来,实现不同许可链之间信息交互。
技术问题
为了克服上述现有技术的不足,本发明提供了一种不同许可链之间的跨链交易。
问题的解决方案
技术解决方案
1、本发明所采用的技术方案是:不同用户在不同的许可链上有加密资产,且他们在另一条许可链上各自开设账户,则不同用户可以通过该许可链进行资产交易。
C企业发行加密资产,A、B企业在C企业所在的许可链(C链)上设有账户,A、B企业分别购买C企业的加密资产。A企业购买价值为X的加密资产,B企业购买价值为Y的加密资产。用户甲在A企业所在许可链(A链)上设有账户,并向A企业购买价值为M的加密资产;用户乙在B企业所在许可链(B链)上设有账户,并向B企业购买价值为N的加密资产。此时用户甲希望向处于不同许可链的用户乙转移价值为Z的加密资产,以下是实现步骤;
步骤S1,用户甲发出将价值为Z的加密资产从A链转移到B链的指令;
步骤S2,用户甲将价值为Z的加密资产从用户甲账户转移到A链上的A企业账户,此时用户甲剩余价值为(M-Z)的加密资产,A链上的A企业账户拥有价值(X+Z)的加密资产;
步骤S3,A链通知C链上的A企业账户向C链上的B企业账户转移价值为Z的加密资产,此时A链上的A企业账户剩余价值为X的加密资产,C链上的A企业账户拥有价值为(X+Z)的加密资产并准备向C链上的B企业账户转移价值为Z的加密资产;
步骤S4,C链上的A企业账户转移给C链上的B企业账户价值为Z的加密资产,此时C链上的A企业账户剩余价值为X的加密资产,C链上的B企业账户拥有价值为(Y+Z)的加密资产;
步骤S5,C链通知B链上的B企业账户向用户乙转移价值为Z的加密资产,此时C链上的B企业账户剩余价值为Y的加密资产,B链上的B企业账户拥有价值为(Y+Z)的加密资产并准备向B链上的用户乙转移价值为Z的加密资产;
步骤S6,B链上的B企业账户向用户乙转移价值为Z的加密资产,此时B链上的B企业账户剩余价值为Y的加密资产,用户乙拥有价值为(N+Z)的加密资产。
2、加密资产可以是加密数字货币,也可以是加密数字资产。
3、不同用户都可以通过所在许可链的许可链节点获取本次交易的交易状态及结果。
4、约定写入一种协议,该协议用于共识服务器校验跨链交易。
5、若判定此次交易失败,用户乙没有收到B企业账户的加密资产,且B企业账户已销毁加密资产,那么即便用户乙获取A企业账户的相关私钥,也无法从A企业账户获取加密资产。
6、加密资产交易的信息需要在有效时间内经过确认才可生效,超过有效时间则会退回。
7、交易信息未在有效时间内生效的情况包括许可链离线、交易地址错误等其它不可交易的情况。
