# Block Timing Becomes a Consensus Attack Surface

As chains compress block intervals toward the physical limits of network propagation, timing manipulation and leader handoff replace cryptographic weakness as the practical attack surface, and the hardware floor for validating becomes the real measure of decentralization.

## Recent evidence

- [confirms] Solana Cuts Block Spacing to About 365 Milliseconds in First Step Toward Sub-Second Finality (2026-08-27): Solana compressed block spacing to about 365 milliseconds while holding a 0.077% skip rate in epoch 1021. Pushing slot times toward propagation limits makes skip rate and leader handoff the operative reliability metric and raises the hardware and bandwidth floor for validating, which is the mechanism the thesis tracks.
- [confirms] Ethereum's Glamsterdam Devnet Extends the Execution-Payload Window From Two Seconds to About Nine (2026-08-21): Glamsterdam's devnet redistributes the slot's internal timing — a roughly nine-second execution-payload window in place of two — making block-timing and builder handoff parameters, not cryptography, the variable that has to be rehearsed on a public test network before mainnet.
