Celestia has officially launched its Lemongrass upgrade, marking a significant milestone in the evolution of its modular blockchain. This upgrade introduces a series of important consensus layer changes designed to enhance scalability, interoperability, and streamline future network upgrades. With a community-driven approach, Lemongrass is set to reshape how the network functions and integrates with other blockchains.
Key Features of the Lemongrass Upgrade
Interchain Accounts (ICA) for Enhanced Interoperability
The Lemongrass upgrade introduces Interchain Accounts (ICA), a highly anticipated feature defined by ICS-27. This allows accounts on Celestia to be controlled by accounts on other IBC-enabled chains, significantly boosting interoperability between Celestia and the wider Cosmos ecosystem. ICA enables seamless cross-chain interactions, making Celestia more flexible for both developers and users who need to engage with multiple blockchain networks.
Packet Forward Middleware (PFM) for Smoother Cross-Chain Transfers
Another critical addition is Packet Forward Middleware (PFM), introduced through CIP-9. PFM simplifies the process of transferring assets across chains. Previously, users needed to bridge assets back to Celestia before moving them to another chain. Now, with PFM, users can sign just one transaction to complete cross-chain transfers, greatly reducing operational overhead and latency. This is a major leap forward in improving cross-chain efficiency.
Simplifying Network Upgrades with CIP-10
A standout feature of Lemongrass is CIP-10, which introduces a new signaling mechanism for smoother network upgrades. Validators can signal their readiness for an upgrade, and once 5/6 of the network's stake has signaled approval, the network automatically migrates to the new version. This streamlines the upgrade process, reducing downtime and ensuring more efficient implementation of future updates.
Enforcing Price Efficiency with CIP-6
To maintain network efficiency and security, Lemongrass also introduces CIP-6, which enforces a minimum gas price for transactions. This mechanism helps prevent spam transactions and encourages more effective resource use. By enforcing a minimum gas price, Celestia ensures that transaction costs are properly accounted for, maintaining the network’s overall performance.
Streamlining Network Architecture with CIP-20
The Lemongrass upgrade also simplifies Celestia’s network architecture by deprecating the Blobstream module, as outlined in CIP-20. The module has been replaced by zk-light clients such as Blobstream X and Blobstream Zero, developed by partners like Succinct Labs and Risc0. This shift reduces overhead for Layer 2 solutions on Ethereum and other settlement layers, making transactions faster and cheaper.
As Celestia continues to evolve, the collaborative efforts of its community will drive further innovations.

Celestia remains dedicated to pushing the limits of decentralized infrastructure, with Lemongrass serving as a key milestone in that journey.
