Liveliness is a critical part of the Interchain Stack and affects operational reliability, scalability, and performance. Ensuring that all nodes can communicate consistently reduces downtime and improves overall system functionality. However, decentralized blockchain development poses significant challenges in providing liveness guarantees at the protocol level. Interchain Foundation announced this groundbreaking news through its official media account, X.

Safety as a priority over liveliness
The Interchain Stack, which includes components such as Cosmos SDK, CometBFT, CosmWasm, and IBC, prioritizes security over liveness as a core design principle. This approach helps maintain network integrity and functionality despite common misconceptions about liveness.
Developers must recognize that while liveliness is important, prioritizing security ensures that the Interchain Stack remains a secure and reliable foundation for innovative blockchain applications. This prioritization is essential to protect billions of dollars in digital assets.
Decentralization requires the collaboration of multiple parties to perform calculations and reach consensus, introducing several unknown factors that affect performance. These challenges make it irresponsible to promise guarantees of liveliness, as the Interchain Stack has never claimed to provide them.
Developers should avoid assumptions about consistent block throughput or timely events and design their applications with these uncertainties in mind. Implementing timeout mechanisms and optimizing resource usage will help maintain functionality during variable network conditions.
Interchain Foundation strategies for improving liveliness
Steward teams are exploring strategies to mitigate liveness issues as the Interchain ecosystem evolves. CometBFT, the consensus engine for the Interchain, has already introduced measures to improve liveliness. For example, reducing the default block size from 21 MB to 4 MB can help manage the impact of high transaction volumes. Additionally, adjustments to timeout parameters and consistent node configurations contribute to improved reliability.
The CometBFT team also focuses on implementing Quality of Service (QoS) measures to prioritize transaction processing. These improvements are intended to prevent network congestion during periods of high demand. The Dynamic Optimal Graph gossip protocol improves the efficiency of transaction distribution, significantly reducing bandwidth usage and improving performance.
