Celestia Launches Payment Architecture Voyager with 21 Million TPS in Benchmark Test

Martian Finance reports that the modular blockchain network Celestia has launched Voyager, an application-specific blockchain architecture designed for large-scale payment scenarios in agent-based commerce. According to the official announcement, Voyager processed approximately 21 million transactions per second continuously across 100 million accounts during its first full benchmark test, which lasted five hours. Celestia states that Voyager splits payment processing into independently scalable threads, avoiding congestion of the execution thread responsible for updating balances. Transactions are first validated for signatures and bundled at the entry layer, then routed into a ring buffer inspired by the Disruptor exchange system. Execution logic is built-in, with state stored in a flat table rather than a Merkle tree. Each transaction is published to Celestia’s data availability protocol, Fibre, enabling external replay and verification of payment correctness. The benchmark covered approximately 400 billion random transfers, achieving an average throughput of 21.2 million TPS and a peak of 21.6 million TPS. Execution ran on a single CPU core with approximately 48 GB of node memory. This test was conducted on a single node and did not include state root computation, cross-machine replication, or real-time state queries at the same scale. Celestia is advancing Voyager toward production and plans to release deeper technical documentation in the coming weeks. Fibre has already gone live on mainnet; Voyager is the first execution-layer product launched following Celestia’s acquisition of Sovereign Labs.
