Celestia launches Fibre, allowing rollups to upload data directly to validators
Celestia activates direct validator uploads via Fibre
Celestia has activated the initial release of Fibre, a new protocol that allows rollups to upload data directly to validators. Rollups are secondary blockchain networks that process transactions and rely on a main network for security and data availability. This update shifts how data is submitted to the Celestia network by letting developers bypass some of the traditional submission pathways.
Key numbers in the initial release
- The protocol supports data chunks, known as blobs, up to 128 MiB in size.
- It allows up to 200 Fibre submissions per block on the network.
- The initial release uses a slower block cadence than the network's earlier terabit benchmark tests.
What the protocol changes for developers
This release marks the beginning of direct interaction between rollup operators and Celestia's validating nodes. While the system is now active, the current specifications limit upload sizes and submission frequency compared to the high-speed capabilities the network has demonstrated in previous benchmarks. The slower cadence means that while direct uploads are possible, the volume and speed are currently constrained to ensure network stability during this launch phase.
