According to @alice_und_bob, a Dec 2, 2025 Twitter post questioned whether a Polkadot core developer just submitted code enabling 500ms block times, noting no commit or PR link in the post. source: @alice_und_bob on Twitter Shorter block intervals are known to reduce inclusion and confirmation latency and can increase effective throughput on proof-of-stake architectures, which is relevant to DEX execution quality and network responsiveness. source: Polkadot Wiki (block production and finality) For trading, monitor the Polkadot SDK/Substrate repositories and official release notes for a merged PR explicitly specifying a 500ms block interval before positioning on this headline. source: Polkadot official GitHub

According to dYdX Foundation, an on-chain governance vote is live asking the community whether to set the NextBlockDelay parameter to 0.2 seconds, with the proposal published as Mintscan Proposal 292 at https://www.mintscan.io/dydx/proposals/292.

According to @AveryChing, Aptos is now recognized for achieving industry-leading 130ms block times and user finality at 650ms, making it one of the fastest blockchains available (source: Twitter/@AveryChing, May 14, 2025). This ultra-fast settlement speed is critical for high-frequency trading and DeFi applications, potentially attracting more active traders and liquidity to the Aptos ecosystem. The performance improvements could directly impact trading volumes, arbitrage opportunities, and overall transaction efficiency compared to slower chains, making Aptos an important blockchain for crypto traders to monitor.
