Celestia unveils Voyager for high-volume payments in agentic commerce
Celestia has introduced Voyager, an application-specific blockchain architecture built for large-scale payment flows in agentic commerce. The company said Voyager handled roughly 21 million transactions per second across 100 million accounts during its first full benchmark, which ran continuously for five hours. In that test, the system processed about 400 billion random transfers, with average throughput at 21.2 million TPS and peak throughput at 21.6 million TPS. Celestia said Voyager separates payment processing into independently scalable threads so the execution thread responsible for balance updates does not get blocked. Transactions are first validated and batched at an ingress layer, then passed into a ring buffer modeled on the Disruptor system used in exchange infrastructure. Execution logic is built in, while state is stored in flat tables rather than a Merkle tree. Each transaction is published to Celestia’s data availability protocol, Fibre, allowing external replay and verification of payment execution. The benchmark ran on a single CPU core with about 48 GB of node memory. Celestia added that the test covered only a single node and did not include state root computation, cross-machine replication, or real-time state queries at the same scale. The company said Voyager is now moving toward production, with deeper technical documentation planned in the coming weeks.
