A key component of the Cosmos ecosystem meant to facilitate interoperability among various blockchains, the inter-blockchain communication (IBC) protocol will be included by core contributor and Ethereum Layer 2 Starknet developer StarkWare. Working with Cosmos contributor Informal Systems, we are integrating.
Cosmos and Starknet run on separate code bases right now. On Ethereum, Starknet is a permissionless distributed ZK-Rolldown acting as a Layer 2 network. While maintaining main network security, it guarantees high throughput and cheap transaction costs using STARK proofs. Conversely, Cosmos is an ecosystem made from many chains created with the Cosmos SDK. These chains talk with one another using the IBC protocol and the Tendermint consensus mechanism.
By means of this integration, Starknet will be able to interact with any IBC-compatible chain, including all Cosmos chains as well as others outside the Cosmos ecosystem that have embraced this capability.
StarkWare clarified that the main goals of this cooperation with Informal Systems are further decentralization and widening the interoperability of Starknet.
“This partnership aims to achieve two primary goals for Starknet: enhancing decentralization and interoperability via exploration of the Tendermint consensus algorithm and the IBC protocol,” it stated.
IBC’s efficiency stems mostly from its use of light client verification. Two chains should not validate their whole counterpart’s state when they want to interact. Rather, they authenticate cryptographic proof connected to transactions on the other chain using light clients, simplified versions of a blockchain node. Working on multiple research and development projects like bringing STARKs to Bitcoin, a ZKThreads framework for “fractal scaling,” parallel transaction processing, and others over the past year, Starkware has been.
