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 @alice_und_bob, Polkadot core developer @bkchr published a write-up on achieving 500ms blocks and refers to the technique as block bundling rather than Basti Blocks, source: @alice_und_bob tweet on September 3, 2025. The tweet provides a link to the write-up and an image but does not state deployment timelines, testnet availability, or benchmark results, source: @alice_und_bob tweet on September 3, 2025. For DOT-focused traders, the absence of timeline and metrics means execution and liquidity impacts cannot be quantified yet and should be monitored via subsequent official updates, source: @alice_und_bob tweet on September 3, 2025.
