Solana infrastructure startup Harmonic raises 6 million USD led by Paradigm

Harmonic, a Solana infrastructure startup, is developing an open block-building system (open block-building system) and has raised 6 million USD in a seed round led by Paradigm, with participation from several angel investors among stakeholders in the Solana ecosystem.

Harmonic stated that this is the first system on Solana that allows validators to receive blocks from multiple competing (block builders) in real-time, helping to increase network speed and performance.

Instead of allowing a single validator to build a block in each round, Harmonic adds a layer of aggregation that helps coordinate and route block proposals similar to the high-frequency trading systems on Nasdaq. Validators can choose priority criteria — for example, to eliminate blocks with harmful MEV or maximize revenue.

Co-founder Jakob Povsic said: “Harmonic brings Solana the ability to route blocks in a Nasdaq-like manner, turning this network into a high-speed on-chain exchange.”

Paradigm asserts that the open aggregation model of Harmonic will transform the block production process on Solana into a competitive market, continuously optimizing, achieving performance equivalent to traditional exchanges in terms of reliability and throughput.

The current development team of Harmonic consists of about 10 members in New York.
