BNB Chain says BEP-590 helped push finality below one second

BNB Chain says its latest consensus-related upgrades have brought the network to sub-second finality, with the project pointing to BEP-590 and BEP-648 as key steps in the process. In an official blog post, the network said production finality has reached about 0.65 seconds after a sequence of upgrades.

The company described BEP-590 as an update that extended voting to recent ancestor blocks, a change it said was meant to absorb network jitter and improve finality speed. It said that approach brought average finality down to roughly 0.9 seconds.

BNB Chain then pointed to BEP-648, which it said added an in-memory vote pool that aggregates votes in real time. According to the network, finality is confirmed at about 0.65 seconds once a two-thirds quorum is reached.

A sequence of upgrades, not a single switch

The blog framed the improvement as the result of a series of BEP upgrades rather than one isolated change. BNB Chain said the move from a 45-second finality model to around 0.65 seconds came through sequential updates, with BEP-590 and BEP-648 among the most recent steps highlighted publicly.

The sub-second result was presented as the outcome of layered consensus changes, not a standalone upgrade with an immediate effect on its own.

BNB Chain’s public thread also linked to the blog for further detail, but the core claim remains the same: the network says it has crossed into sub-second finality on production systems.
