The blockchain is an emerging technology which has the potential to improve many information systems. In this regard, the applications and the platform they are built on must be able to connect and communicate with each other. However, the current blockchain platforms have several limitations, such as lack of interoperability among different systems. The existing platforms of blockchain applications operate only within their own networks. Even though the underlying technology is similar, it relies on centralized third-party mediators to exchange or retrieve information from other blockchain networks. The current third-party intermediaries establish trust and security by preserving a centralized ledger to track ‘account balances’ and vouch for a transaction’s authenticity. The inability for independent blockchains to communicate with one another is an inherent problem in the decentralized systems. Lack of appropriate inter-blockchain communication puts a strain on the mainstream adoption of blockchain. It is evident that blockchain technology has the potential to become a suitable solution for some systems if it can scale and is able to cross communicate with other systems. For the multisystem blockchain concept to become a reality, a mechanism is required that would connect and communicate with multiple entities’ blockchain systems in a distributed fashion (without any intermediary), while maintaining the property of trust and integrity built by individual blockchains. In this article, we propose a mechanism that provides cross-chain interoperability using transactions.

使用交易的基于区块链的系统之间的跨链互操作性

区块链是一种新兴技术，具有改善许多信息系统的潜力。在这方面，应用程序和它们所构建的平台必须能够相互连接和通信。然而，当前的区块链平台存在一些局限性，例如不同系统之间缺乏互操作性。现有的区块链应用平台只能在自己的网络中运行。尽管底层技术相似，但它依赖于中心化的第三方中介来交换或检索来自其他区块链网络的信息。当前的第三方中介通过保留一个集中式分类账来跟踪“账户余额”并保证交易的真实性来建立信任和安全性。独立区块链无法相互通信是分散系统中的一个固有问题。缺乏适当的跨链通信给区块链的主流采用带来了压力。显然，如果区块链技术可以扩展并能够与其他系统交叉通信，它就有可能成为某些系统的合适解决方案。为使多系统区块链概念成为现实，需要一种机制以分布式方式（无需任何中介）与多个实体的区块链系统连接和通信，同时保持单个区块链构建的信任和完整性属性。在本文中，我们提出了一种使用交易提供跨链互操作性的机制。
