Priority Fast Lane

When Speed Matters

Sometimes you need your message included now:

• Breaking news

• Time-sensitive attestations

• Auction bids

• Game moves

• Emergency alerts

The Priority Message Queue (PMQ) guarantees fast inclusion for those who need it.

How It Works

Standard Lane (SMQ)          Priority Lane (PMQ)
┌──────────────────┐         ┌──────────────────┐
│  Free + VDF      │         │  Bid ≥ 0.001 OBS │
│  FIFO order      │         │  Highest bid wins│
│  Wait your turn  │         │  Next block      │
└──────────────────┘         └──────────────────┘

Bidding

Bid Level	Typical Result
0.001 OBS	Included if PMQ not crowded
0.01 OBS	Usually top priority
0.1+ OBS	Guaranteed front of queue

Check current competition:

const status = await provider.send("eth_getMessageQueueSize", []);
console.log("Top bid:", status.topBid);

Reserved Space

Priority messages can't crowd out free messages—each has dedicated block space:

• PMQ slot: 5 MB per message block

• SMQ slot: 5 MB per message block

Even if PMQ is flooded, SMQ still gets its space (and vice versa).

Fee Distribution

Your bid supports the network:

• 30% → Block proposer

• 70% → Archive node pool

Fast inclusion and funding data preservation.
