Celestia Says Fibre Sustained 3.07 Tb/s In 120-Validator Benchmark

Summary

Celestia reported a 3.07 terabits-per-second throughput benchmark for Fibre, its high-throughput data-availability system, tested across 120 validators. The system sustained this rate while encoding blobs, distributing and storing data shards, collecting validator signatures, and submitting commitments onchain. The result is a notable engineering milestone, but it is a benchmark, not live production activity. Celestia estimates that, under its test assumptions, this capacity could support nearly two billion transactions per second in raw data terms. The broader significance is that data availability is becoming a distinct bottleneck as blockchain architectures separate execution from settlement and data publishing. Real-world performance will still depend on latency, adversarial conditions, hardware diversity, geography, and economic constraints.
