WeCross是由微众银行自主研发并完全开源的区块链跨链协作平台,致力于促进跨行业、机构和地域的跨区块链信任传递和商业合作。WeCross不局限于满足同构区块链平行扩展后的可信数据交换需求,还进一步探索解决异构区块链之间因底层架构、数据结构、接口协议、安全机制等多维异构性导致无法互联互通问题的有效方案。

WeCross整体架构设计

  • 数据层:跨链交互的核心是数据在链间的流动,数据层的抽象就尤为重要。跨链涉及的数据维度包括区块、交易、合约、消息等多个方面。WeCross以满足跨链基本要求为前提,提炼通用区块数据结构,将交易、合约和消息等抽象设计成资源类型,为资源设计通用的寻址协议。

  • 交互层:不同业务场景有不同的跨链交互模型,基于抽象数据层,WeCross建设通用区块链适配与路由中继网络,结合标准默克尔证明机制,实现跨链交互层抽象设计。

  • 事务层:基于数据结构和交互的抽象层,实现跨链事务效果。目前支持两类机制:两阶段事务和哈希时间锁定事务。未来将依据场景需求设计更多事务机制。

WeCross四大技术

  • 通用区块链接口:本着“求同存异”、“聚焦最大公约数”的基本思路,通用区块链接口对交易、智能合约与资产等数据进行抽象包装,设计统一的资源范式,设计普适跨链场景的抽象区块数据结构,为异构区块链的交互建立数据协议一致的基础,实现“一次适配,随处可用”的效果。

  • 异构链互联协议: 尽管各家区块链平台的内部架构、网络模型和共识逻辑有很大差异,但这些区块链平台的对外接口存在共性。异构链互联协议通过分析主流区块链平台交互方式的共性点,提炼一种通用的区块链接入范式与跨链交互模型。

  • 可信事务机制:区块链内部的安全机制在面对跨区块链调度时会突破安全边界,无法实现可信与事务。可信事务机制提出数据互信机制和跨链事务机制,解决区块链可信问题和交易事务性的问题。

  • 多边跨域治理:多边跨域治理是一套完整的区块链多边治理方案,支持多个区块链按照其业务需求,以不同的网络拓扑来组建跨链分区。
