Everything You Need to Know About the Cosmos Hub v19 Upgrade

Devashri Kulwal • 2024-08-24

The Cosmos Hub has successfully upgraded to Gaia v19, making Hub the reference chain for the Interchain Stack's latest and greatest innovations. (You can read the forum post here.) This update is not just about minor tweaks; it's a comprehensive overhaul to enhance efficiency, security, and functionality of the Cosmos Hub, making it better equipped to handle the demands of the rapidly growing interchain ecosystem. The Hub is now integrated with the latest versions of the Interchain Stack:

  • Cosmos SDK v.0.50

  • IBC v8.4.0

  • CometBFT v0.38.11

  • Interchain Security v5.1.1

Key changes and features

  1. Cosmos SDK v.0.50 One of the most anticipated aspects of this upgrade is the integration of Cosmos SDK v0.50. In collaboration with Binary Builders, this version is a major milestone, bringing several performance enhancements and developer focused improvements. It reduces coding efforts, enhances data access speeds, and boosts overall efficiency - critical for developers building on the Cosmos Hub. It unlocks a smoother and faster development process, enabling more robust and scalable applications within the Cosmos ecosystem.

  2. IBC v8.4.0 The Inter-Blockchain Communication (IBC) protocol gets a significant boost with this version. IBC is a feature of Cosmos that allows blockchains to talk to each other. Chains that speak IBC can share any type of data as long as it's encoded in bytes, enabling the industry’s most feature-rich cross-chain interactions. The standout feature of this upgrade is channel upgradability, which allows chains to leverage new application and channel features without having to create new channels or perform a network-wide upgrade. This flexibility is particularly beneficial for developers and users, ensuring that the Cosmos network can evolve rapidly without disruptions.

  3. CometBFT v0.38.11 This update includes ABCI++ (Application BlockChain Interface), which provides greater consensus flexibility. The inclusion of the Vote Extension feature means that validators can now perform additional actions beyond just validating blocks. This is a crucial step towards enhancing the overall security and functionality of the Cosmos Hub, particularly in maintaining network consensus under various conditions.

  4. Interchain Security v5.1.1 This version of ICS is fully compatible with the latest versions of the Cosmos SDK and CometBFT. This ensures smoother integration and operation across the Cosmos ecosystem, thereby enhancing the security and reliability of the interchain services that the Cosmos Hub supports.

Why does this upgrade matter?

The Cosmos Hub v19 upgrade is a critical step forward for the Cosmos ecosystem. By integrating the latest versions of its core technologies—Cosmos SDK, IBC, CometBFT, and Interchain Security—the upgrade ensures that the Hub remains at the forefront of innovation.

The ability to upgrade channels without disrupting the network (thanks to IBC v8.4.0) and the added consensus flexibility with CometBFT v0.38.11, is beneficial to developers and projects looking to build and deploy decentralized applications that require both robustness and agility.

In conclusion, the Cosmos Hub v19 upgrade is not just an incremental update but a substantial enhancement that will drive the next wave of growth and innovation within the Cosmos ecosystem.

Whether you're a developer, a validator, or a holder, this upgrade brings tangible benefits that will make the Cosmos Hub more efficient, secure, and ready for the future of blockchain technology.
