Stellar (XLM) previews Project Thruput, a fee-free compute model

Stellar (XLM) said on 2026-10-28 that it is previewing Project Thruput, a new execution model it says can expand blockchain compute by adding machines rather than rationing throughput through transaction order or per-transaction fees. In benchmark results cited by the Stellar Development Foundation, execution capacity inside a single validator rose from 1.18 million payments per second on one machine to 7.02 million on eight machines. According to the foundation's announcement published on 2026-10-28, Project Thruput is live on FutureNet as a technology preview with open-source code, white papers and reproducible benchmarks. The model is designed to let transactions start from the same ledger snapshot and execute side by side, even when they touch the same state, with compatible changes merged at commit time.
