Celestia Labs is targeting machine-to-machine micropayments with Voyager, a new blockchain architecture for agentic commerce. It is the first execution layer built on Celestia Fibre, which went live on mainnet on October 19, and the first product since the July acquisition of Sovereign Labs.

In its first full benchmark, a single Voyager node averaged 21.2M transactions per second across 100M accounts over five hours, peaking at 21.6M and processing about 400B transfers.

The design splits processing into independent threads around a ring buffer, keeps payment logic built in rather than on a general-purpose VM, and publishes every transaction to Fibre so anyone can replay it. Execution ran on one CPU core with memory flat at about 48 GB.

The figure covers a single node: it does not yet compute state roots, replicate data to other machines or serve real-time status queries at this volume. Celestia says it is taking Voyager toward production, with those components next.
