Slot Marketplace (siQoS)

The Raiku Slot Marketplace implements our Slot-Inclusion Quality of Service (siQoS) mechanism. It is a marketplace for Compute Units (CUs) that turns blockspace into a guaranteed, programmable resource. Rather than relying on Solana's standard probabilistic fee market, users can purchase guaranteed transaction inclusion through transparent auction mechanisms.

How It Works

The marketplace allows users to reserve blockspace deterministically at a known price for a known time. This creates certainty that applications and businesses can plan around, eliminating the guesswork of traditional transaction submission.

Key Features

• Guaranteed inclusion: No more dropped or failed transactions during congestion
• Transparent pricing: Fair value discovery through auction mechanisms
• Flexible timing: Choose immediate execution (JIT) or schedule for future slots (AOT)
• Enterprise reliability: 99.9%+ expected inclusion rate

Auction Models

JIT Auctions

• First-price sealed-bid auction model
• Minimum price set at current priority fee plus 5% premium
• Optimized for speed and immediate execution
• Ideal for time-sensitive operations

AOT Auctions

• Open English-style auction format
• Users bid against each other for specific future slots
• More efficient price discovery for planned blockspace
• Often rewards advance planning with lower fees

Dynamic Slot Allocation

The marketplace intelligently balances capacity between JIT and AOT transactions to prevent starvation of either path. Allocation adjusts dynamically based on real-time demand while maintaining fairness through transparent ordering rules.

// Example: Query available slots
const availableSlots = await raikuClient.getAvailableSlots({
  type: 'AOT',
  minSlotsAhead: 35,
  limit: 10
})

// Reserve a slot
const reservation = await raikuClient.reserveSlot({
  slotNumber: availableSlots[0].slotNumber,
  bid: 0.0045,
  transaction: myTransaction
})
