Description
Fibre Blockspace operates in parallel with Celestia’s existing L1 data availability protocol and is run by the Celestia validator set. It uses ZODA-based encoding, direct blob distribution to validators, and validator signatures. Fibre blockspace supports blob sizes from 256KB to 128MB and targets power users and high-throughput rollups. It was undergoing testing, with an Arabica testnet rollout and incremental mainnet deployment planned.
