Stellar’s Project Thruput Benchmark Records 7.02 Million Payments per Second

Stellar Development Foundation has put Project Thruput on FutureNet as a technology preview, with its benchmark recording 7.02 million payments per second across eight machines in one validator.

The one-machine result was 1.18 million payments per second. These figures measure transaction execution within a validator; they do not measure consensus or end-to-end performance across the Stellar network.

The tests ran RV32 ERC-20 transfers among 100 accounts under heavy contention. Each reported figure was the middle result from three trials using AWS r8a.16xl machines.

Project Thruput starts transactions from the same ledger snapshot and runs them in parallel, including transactions that touch the same state. At commit time, it combines changes that are compatible. The approach is designed to let transactions use available computing capacity without making every transaction wait for the prior one to finish.

The model has no per-transaction fees, though gas still measures and caps each transaction’s execution. When demand exceeds capacity, an account’s share of scheduling capacity depends on its unlocked native-token balance. Storing data requires a refundable token lock.

The benchmark adds a new result to TokenPost’s earlier coverage of Project Thruput’s introduction. The FutureNet release is a technology preview; no mainnet rollout date was provided.
