Celestia Prepares for ‘Ginger’ Upgrade, Doubling Data Availability Throughput

Share

In a significant move for blockchain scalability, Celestia is gearing up for its second major consensus upgrade, known as ‘Ginger,’ following the successful deployment of ‘TheLemongrass’ upgrade to Mainnet Beta in September. The Ginger upgrade, also referred to as celestia-app v3, promises a substantial enhancement in data availability throughput by reducing block times from 12 seconds to 6 seconds.

This upgrade not only doubles the throughput but also improves user experience with faster transaction finality times. The Ginger upgrade is scheduled to activate at Arabica height 2348907, expected on November 5, 2024, and will reach the Mocha testnet in November, followed by Mainnet Beta in December.

Key Features of the Ginger Upgrade

The Ginger upgrade encompasses several Celestia Improvement Proposals (CIPs), as detailed in CIP-25. One of the notable changes is the implementation of BBR (Bottleneck Bandwidth and Round-trip propagation time), a congestion control algorithm developed by Google. BBR is designed to enhance real-life peer-to-peer network performance by using round-trip time to detect congestion, leading to significant throughput improvements.

Another important update is CIP-21, which introduces ‘authored blobs’ that include the signer’s address in the blob metadata. This streamlines the verification process for rollups, allowing them to directly verify the blob’s authenticity without additional processing.

CIP-24 sets the gas scheduler variables to be modifiable only through network upgrades, aiming for more stable and predictable transaction costs. CIP-26 reduces block time and adjusts related timeouts, while CIP-27 introduces limits on the number of PayForBlobs (PFBs) and non-PFB messages per block to prevent long processing times.

Implications for Network Scalability

CIP-28 sets a limit on the size of individual transactions to 2MiB, a consensus-breaking change that prevents issues with large transactions. This change is part of a broader strategy to improve network scalability and performance, allowing for future increases in block size and throughput.

The Ginger upgrade is a significant step forward for Celestia, paving the way for enhanced scalability and performance in decentralized networks. For more detailed information on the Ginger upgrade, including timing and node update instructions, visit the official Celestia blog.
