A Unified Cross Chain Security Model: Improving Interoperability in the Blockchain Ecosystem

On April 15, it was reported that in the 2023 Hong Kong Web3 Carnival Cross chain Special Session, Luke Liu, the core contributor of Poly Network ecology, believed that the establishment of a unified cross chain security model would help us systematically understand the risks of interoperability. The goal of cross chain communication is to standardize the communication process, ensuring that requests on one chain are correctly and smoothly executed on another chain. Each chain is different, but we strive to establish a unified risk model that includes three stages: data request, communication, and verification. Through mathematical (model) abstraction, the multi chain interoperability in the blockchain system includes the collaboration of different layers such as application, communication, consensus, etc. This set of combined interaction system not only relies on the security of each component, but also tests the security of interaction between components. Establishing such a (security) framework can help us understand interoperability risks more systematically rather than generalizing them based on individual cases.

Poly Network Ecological Core Contributor: Establishing a unified cross chain security model helps us systematically understand interoperability risks

Blockchain interoperability is a crucial functionality necessary for the full realization of the potential of the blockchain technology. It allows seamless communication and transaction execution between different blockchains, allowing the transfer of assets and data between otherwise isolated ecosystems. However, with interoperability comes the risk of security breaches and attacks, which can have far-reaching consequences. In this article, we’ll explore the concept of a unified cross chain security model, its benefits, and how it can help us systematically understand the risks of interoperability.

The Article

Blockchain technology has revolutionized the way that we transact and communicate online. The ability to create and store digital assets, and transfer them among participants in a trustless and secure manner is a game changer. However, one of the biggest challenges to the full realization of the blockchain’s potential is blockchain interoperability.
Interoperability refers to the ability of blockchain networks to communicate and interact with each other, allowing for the transfer of assets and data between otherwise isolated ecosystems. This functionality is crucial for creating a unified blockchain ecosystem, but it also introduces new security risks, especially if the communication between chains is not secure.
To address this challenge, Luke Liu, the core contributor of Poly Network ecology, has suggested the establishment of a unified cross chain security model. Such a model would allow us to systematically understand the risks of interoperability, while maintaining specificity and context.
The goal of cross chain communication is to standardize the communication process, ensuring that requests on one chain are correctly and smoothly executed on another chain. To achieve this, cross chain communication follows three stages: data request, communication, and verification.
Multi-chain interoperability in the blockchain system includes the collaboration of different layers such as application, communication, consensus, etc. This set of combined interaction system not only relies on the security of each component, but also tests the security of interaction between components. Because each chain is different, it is ideal to establish a unified risk model that includes each of the three stages of cross chain communication.
Through mathematical (model) abstraction, it is possible to model and understand the behavior of multiple chains interacting with each other, including the security risks that arise. By doing so, we can establish a (security) framework that helps us understand interoperability risks more systematically rather than generalizing them based on individual cases.
The establishment of such a framework has many benefits. By systematically understanding interoperability risks, we can develop countermeasures that are more effective in mitigating real-world threats. Moreover, a unified cross chain security model will allow for more specific and context-rich discussions on interoperability risks, ultimately leading to more informed decision-making.
In conclusion, blockchain interoperability is crucial for creating a unified blockchain ecosystem. However, without proper security measures in place, it can introduce significant risks. The establishment of a unified cross chain security model helps us systematically understand the risks of interoperability, leading to more effective countermeasures and informed decision-making. There is a need for further research in this area, as the development of such a model is pivotal for the successful realization of the full potential of blockchain technology.
