Key Takeaways
- • Celestia Fibre achieved a peak throughput of 3.07 terabits per second (Tb/s) in testing, translating to approximately 2 billion transactions per second and exceeding Visa's 2025 annual transaction volume within minutes of operation.
- • The network sustained 1 Tb/s of data throughput in partial benchmarks, supporting 625 million+ transactions per second—representing a significant scaling achievement for blockchain-based data availability infrastructure.
- • Celestia's modular architecture, enhanced by recent upgrades including Matcha and v9, now supports 128 MB blocks with 3-second block times, achieving ~27 MB/s throughput and delivering over 160× performance improvement since network launch.
- • The Fibre protocol positions Celestia as a data availability layer capable of serving ultra-high-throughput rollups, addressing the fundamental bottleneck of monolithic blockchain design through specialized, modular infrastructure.
- • Celestia's throughput milestones establish a clear technical pathway toward 1 gigabyte blocks, positioning the network to fundamentally redefine blockchain capacity benchmarks relative to traditional payment systems like Visa.
Summary
Celestia has announced a major performance milestone with its Fibre protocol achieving 3.07 terabits per second (Tb/s) of throughput in testing environments. This benchmark represents a substantial advancement in blockchain data availability capacity, translating to approximately 2 billion transactions per second—a volume equivalent to Visa's entire 2025 annual transaction processing within minutes of operation. The partial benchmark demonstrated sustained throughput of 1 Tb/s, supporting 625 million or more transactions per second, establishing new performance standards for modular blockchain infrastructure.
The achievement reflects the cumulative impact of recent network upgrades, specifically the Matcha and v9 updates, which expanded block capacity to 128 MB with 3-second block times. Under these parameters, Celestia has achieved approximately 27 MB/s of throughput, representing over 160 times the performance of the network at launch. These incremental improvements have systematically addressed throughput constraints that historically limited blockchain scalability, moving beyond the monolithic architecture paradigm toward specialized, modular layers optimized for specific functions.
Celestia's Fibre protocol was explicitly engineered to enable ultra-high-throughput rollups by functioning as a dedicated data availability layer rather than a full consensus mechanism. This architectural approach decouples data availability from transaction execution and settlement, allowing applications to leverage Celestia's infrastructure without managing the full overhead of independent blockchain validators. The network's current technical trajectory suggests a credible path toward 1 gigabyte blocks, which would further multiply transaction capacity and establish Celestia as a foundational utility for scaling blockchain applications.
The throughput achievements carry strategic implications for institutional adoption of blockchain infrastructure. Where Visa's historical throughput of approximately 24,000 transactions per second once represented the industry benchmark for payment systems, Celestia's demonstrated capacity—measured in billions of transactions per second—reframes expectations for decentralized infrastructure performance. For hedge funds, institutional investors, and family offices evaluating blockchain-based systems, these performance metrics suggest that technical limitations previously constraining on-chain adoption have been substantially addressed within Celestia's modular framework.
