TechFlow news, November 5 — According to The Block, Harmonic, a Solana infrastructure startup, has raised $6 million in seed funding led by Paradigm.
Harmonic is developing an open block-building system, reportedly the first startup enabling Solana validators to receive blocks in real time from multiple competing builders. The system aims to coordinate and aggregate layers to replace bottlenecks in the existing architecture, routing builder proposals to validators in real time, and introducing a structured block propagation mechanism akin to high-frequency trading order routers.
