控制权与所有权一致的企业级分布式账本

WeBankBlockchain-OpenLedger

OpenLedger聚焦链上的“用户、业务方、权益、账户和账本”，建立与实际业务匹配的账本体系，承载数字化权益的完整生命周期，以此形成多方参与的可信分布式账本。

关键特性

• 职责分离的托管人机制

  业务方面向用户提供服务、管理账户；托管人负责权益上链登记、保管账本、维护链上权益与实际价值的一致性；用户控制自身账户权益、通过私钥发起权益流转交易。区块链记录、保存、同步交易日志，保障链上权益安全、一致、可靠，从而形成可信的分布式账本。

• 灵活的账户体系

  组织可以根据业务需要，授予多名员工操作本企业账户的权限。

• 安全可信的双重签名机制

  用密码学算法强化用户的控制权。交易必须由用户和业务方联合签名才能上链。用户在链下对交易数据进行第一次签名，并将签名后的数据发送给业务方，业务方进行第二次签名后提交上链。

• 双模式记账体系

  支持基于余额数量变化的记账模型和基于所有权变化的记账模型。

fisco bcos 2.7.2-gm下报args or nonce not verify

sdk已启用国密特性,OrgService.createAccount报"createAccount failed :args or nonce not verify",nonce=0
另外createAddOrgAdmin结果adminInnerAddr与adminAddr不一致，adminInnerAddr有什么用？
在多租户SaaS平台合约是否支持
谢谢！
