A new era for Cosmos
Join the biggest event in the ecosystem since the launch of the Cosmos Hub.

Stargate is a set of upgrades that complete the original roadmap laid out in the Cosmos Whitepaper. For the first time ever, Cosmos blockchains will be able to connect with each other using the first standardized protocol for inter-blockchain communication (IBC).

What’s new?
These upgrades bring significant performance improvements to blockchains built with Cosmos SDK. Discover all the amazing features of the Stargate upgrade below.
Efficiency gains up to
Faster full node sync
Faster upgrades
Inter-Blockchain Communication
Cosmos SDK-based blockchains can incorporate the Inter-Blockchain Communication (IBC) Protocol to communicate with other compatible blockchains. The Cosmos Hub is the first blockchain to support IBC in production.
State Sync
For blockchains built on top of Tendermint Core, the full-node synchronization process will be reduced from 2 days to just 30 mins or less.
Automatic upgrades
The upgrade module facilitates the upgrade process of chains built with Cosmos SDK. Migration from one version to the next will take little to no time, as opposed to one hour or more before.
Full-featured Light Clients
Light clients are lightweight alternatives to a full node, allowing a wide range of devices to safely and efficiently receive blockchain data for new network nodes and inter-blockchain communication.
Transition from Amino to Protobuf
Protobuf brings performance improvements and developer acceleration to Cosmos SDK-based blockchains with efficiency gains of 10-100x, and wider language support.
