ChainCatcher message, based on the Cosmos liquid staking protocol Stride, plans to transition from the existing STRD token model to the Inter-Chain Security (ICS) system driven by ATOM tokens. Stride contributor Ian Unsworth stated, "The transition may occur between Wednesday 17:00 and 21:30 (UTC), at block height 4616678."Unsworth added, "While Stride's TVL has reached over $35 million, it only has $19 million in economic security through bonded network tokens. After the ICS transition, block production/security will be passed to the ATOM validator set, which will increase the economic security of the network by approximately 11,935.2%."According to the official blog, the transition to ICS will raise Stride's economic security from about $25 million to $2.3 billion, making the protocol more resilient against hacking attacks.

ChainCatcher news, according to The Block, multiple Cosmos ecosystem projects are leading the development of a new cross-chain security model called "mesh security" based on the decentralized exchange Osmosis. This model aims to combine staked assets from two or more blockchains to enhance the security of the Cosmos ecosystem.The development of this model is funded by Osmosis and is being developed in collaboration with Axelar, Akash Network, and ATOM Accelerator DAO. The mesh security plan is expected to be completed in three phases, with each phase estimated to last about three months.Sunny Aggarwal, co-founder of Osmosis Labs, stated, "With the introduction of mesh security, we can approach security bidirectionally, meaning that two chains, such as Osmosis and Juno, can provide security to each other."

ChainCatcher message, at the 2023 Hong Kong Web3 Carnival cross-chain session, Poly Network ecological core contributor Luke Liu believes that "establishing a unified cross-chain security model helps us systematically understand interoperability risks.The goal of cross-chain is to standardize the communication process, ensuring that requests on one chain are executed correctly and smoothly on another chain.Each chain is different, but we strive to establish a unified risk model that includes three aspects: data requests, communication, and verification. Through mathematical (model) abstraction, multi-chain interoperability in blockchain systems involves the collaboration of different layers such as applications, communication, and consensus. This set of combinatorial interaction systems relies on the security of each component and also tests the security of interactions between components.Establishing such a (security) framework can help us understand interoperability risks more systematically, rather than inductively based on individual cases.Security audit techniques often determine whether all necessary security elements for a project are covered based on a checklist, which also includes automated execution of security analysis. Based on existing security audit techniques, business logic and security attributes can be further mathematized, serving the project more explicitly.Poly Network is also building a simpler and safer programming model to facilitate the development of multi-chain applications."
