PANews reported on November 5th that Harmonic, the Solana ecosystem infrastructure project, has completed a $6 million seed funding round led by Paradigm, with participation from several key Solana stakeholders as angel investors.

Harmonic aims to build Solana's first open block building system, which helps validators obtain the optimal block by aggregating bids from multiple block builders in real time. This system addresses the problem of excessive concentration of block building power in the current Solana network, and its operation is similar to an order routing system in high-frequency trading.
