Flashblocks

Ultra-fast transaction execution on Flash-Blocks supported chains with Tachyon's flashblocks feature. Reduce transaction latency from 150ms to under 50ms for lightning-fast user experiences.

Overview

Flashblocks is Tachyon's high-speed transaction type that delivers ultra-low latency execution on Flash-Blocks supported chains. While standard Tachyon transactions already execute in under 150ms, flashblocks push the boundaries further with sub-50ms average latency, making them perfect for real-time applications, gaming, and high-frequency trading where every millisecond counts.

Performance Comparison
