Flowra Launches Open Orderflow Auction for Solana Block Building

Flowra has launched its Open Orderflow Auction (OOA), a new block-building system for Solana that introduces competitive bidding for transaction inclusion.

The OOA is designed to create more competition around transaction ordering and give validators a larger share of the value generated by MEV. According to Flowra, this approach could improve price discovery while giving validators more opportunities to earn from the demand for Solana blockspace.

Early testing showed promising results, with a 20.6% increase in compute units per block on one validator, taking it from 84% to 101% of the network average.
