I used to view fast finality as a rather dry, technical metric. But when you actually trade on a high-throughput blockchain, you realize its impact is almost immediate.

I’ve run high-frequency trading for years, so I understand well how slow finality can affect things. Some arbitrage opportunities exist for only a fleeting moment—by the time the transactions get confirmed, the price has already moved and the profit window is closed.

I began to see that fast finality is genuinely valuable when a chain can finalize transactions in under a second. The feeling is completely different. Bots can capture spreads more tightly, market makers update prices faster, and liquidity seems to react to the market rather than always lagging behind it.

For me, this isn’t simply a matter of the blockchain running faster. Once the trading experience changes, the way the entire on-chain market reacts to one another starts to change too.

But there’s one thing I think people are overlooking: fast finality doesn’t naturally make the whole system fast. If the RPC, indexer, or execution layer is still slow, you’re only moving the bottleneck elsewhere.

Honestly, the more I observe, the more I see that chains solving this problem well are gradually becoming the infrastructure layer behind truly serious on-chain trading activity.

I’m curious: is there any network where, when you trade on it, you can genuinely feel the advantage of fast finality? Share a few names.@Dusk #dusk $DUSK $HANA $AKE
