opBNB just rolled out its Fourier mainnet hardfork, slashing block time in half—from 500ms down to 250ms. That's a serious speed bump. The whole point of opBNB is to deliver BNB Chain's power without the congestion: faster throughput, way lower transaction costs. If you're tired of waiting for blocks or watching fees stack up, this upgrade matters. It's the kind of incremental polish that keeps networks competitive when user demand actually picks up.
