Celestia's Fibre Network Reaches Record Throughput in Full-Pipeline Benchmark Test
Celestia reported that its Fibre technology achieved sustained throughput of 3.07 terabits per second across a 143-second benchmark involving 120 validators, demonstrating the capacity to process roughly 2 billion transactions per second. The full end-to-end test included encoding, distribution, storage, signature collection, and onchain commitment, setting it apart from earlier partial demonstrations. The company achieved an 7.5x improvement in encoding speed through vectorized Reed-Solomon coding and increased block capacity from 200 to 2,000 during testing.
Celestia's engineering improvements centered on optimizing the encoding process that prepares data for network distribution. By implementing vectorized Reed-Solomon coding using ARM NEON processor instructions, the company achieved a sevenfold speed increase in how quickly blobs are prepared for validators. The test parameters pushed block capacity substantially higher than typical operations, raising the submission limit from 200 to 2,000 blocks and reducing block time to one second, demonstrating potential scaling headroom under experimental conditions.
The benchmark's significance lies in its end-to-end scope. Rather than measuring isolated components, Celestia ran validators through the complete workflow: encoding blobs into distributable pieces, storing those pieces across the network, collecting cryptographic signatures confirming receipt, and finally recording commitments onchain. This full-pipeline approach provides stronger evidence of viability than partial tests, though the company acknowledges that mainnet deployment will operate under more conservative settings than those used during peak benchmark performance.
If achieved at scale, Celestia's throughput capacity could enable blockchain applications requiring sustained high data rates—such as rollups, data availability services, or enterprise settlement layers—to operate with reduced congestion and potentially lower fees. Network operators, application developers, and users of data-heavy blockchain services may benefit from increased processing capability. However, translating benchmark results into stable production performance at reduced settings, maintaining decentralization as validators scale their infrastructure requirements, and managing storage demands across the validator set remain implementation challenges that could affect real-world utility.
