With block times hovering around 50ms, Aptos has emerged as one of the fastest mainnet L1 solutions currently live. This level of latency fundamentally changes what's possible—onchain HFT, which has long remained theoretical for most networks, suddenly becomes practical and economically viable here. The speed advantage isn't just a marketing point anymore; it's becoming a real technical differentiator that opens up entirely new use cases. When transaction finality happens that quickly, the whole game shifts.
