跨链是一种解决两个或多个不同链上的资产以及功能状态互相传递、转移、交换的协议，能够增加区块链的可拓展性，从根本上解决不同公链/侧链之间交易困难产生的“数据孤岛”问题。侧链是主链外的另一个区块链，锚定主链中的某一个节点，通过主链上的计算力来维护侧链的真实性，实现公共区块链上价值与其他账簿上价值在多个区块链间的转移。最具代表性的实现有Blockstream。主链和侧链协同的架构中主链也被称为母链（Parent chain）。代表项目包括Polkadot（中继链+平行链跨链架构）、Cosmos（IBC跨链通信协议）、Polygon（以太坊侧链）、Bitcoin侧链（Blockstream Liquid Network）等。主要成就：2015年Blockstream提出侧链白皮书；2020年Polkadot主网上线实现异构跨链；2020年Cosmos SDK推动IBC跨链协议落地；2021年Polygon以太坊侧链TVL突破100亿美元；跨链桥技术持续演进，安全审计与去中心化程度不断提升。
