The first transaction to benefit from STPS was Signum’s multi-out payment in 2018. This transaction type enabled the Signum chain to conduct a pay-out up to 128 recipients in one transaction. This pushes the STPS from 1,020 to 19,200 per block (new block every 4 minutes). This increased the regular capacity from 4.25 TPS to 80 TPS for a given block size of only 179,520 bytes.
