# Introdution

### Open Orderflow Auction(OOA) for Solana

> **Maximize validator revenue and protect users through a transparent Open Orderflow Auction.**

***

### The Problem is Structural

Solana's Gulf Stream design means there is **no public mempool.** Transactions are pushed directly to the next leader without being broadcast to the network — which means MEV and orderflow are monopolized by a handful of infrastructure providers operating in the dark.

This creates three compounding problems.

1. **User over-payment** — Information asymmetry in the fee market causes users to pay far more Priority Fee and Tip than necessary.
2. **Jito single-point dependency** — 94%+ of validators by stake rely on Jito with no real alternative, forced to accept unilateral policy changes.
3. **Opaque MEV** — Sandwich attacks and private orderflow deals happen without any external verification, with the costs borne by users and the ecosystem.

***

### Flowra's Answer

We build an **Open Orderflow Auction** on top of Solana.

Multiple validators share their pending transactions to form an open stream. From there, a publicly competitive auction runs — open to any searcher. MEV cannot be eliminated. But when it's made transparent and competitive, everyone wins.
