What is Raiku?

Raiku is an execution layer that makes transaction execution on Solana predictable by turning blockspace into a schedulable, market-priced resource.

Raiku Over the last few years, Solana has become one of the fastest and most scalable blockchains in the world. Its speed has attracted developers, startups, enterprises, and institutions alike giving rise to the phrase: “Only possible on Solana.”

But as Solana usage has grown, one challenge has become clear: speed alone is not enough. When demand spikes, transactions can fail, arrive late, or execute inconsistently. For applications that depend on precision, scale, and reliability, this is a serious limitation. This is where Raiku comes in.

In simple terms, Raiku turns blockspace into something you can reserve, schedule, and rely on.

Solana as a super-fast highway.


Today, applications on Solana:

This creates a probabilistic system where users can pay more but still have no guarantee their transaction will execute. Without reliable execution, blockchains cannot power global-scale products.

What Makes Raiku Different

Raiku introduces deterministic execution. That means execution timing and inclusion are known in advance, not guessed through fees.

Traditional Execution

  • • Fee guessing
  • • Spam-heavy
  • • No guarantees

Raiku Execution

  • • Scheduled execution
  • • Market-priced blockspace
  • • Guaranteed inclusion

Why This Matters for Real Businesses

Modern applications especially financial ones need more than just speed. High-frequency trading firms require transaction confirmations in under 30 milliseconds, not the ~400ms seen today. Institutions need deterministic transaction ordering, and enterprises require regulatory and operational certainty before moving fully on-chain. Without these guarantees, large-scale businesses cannot reliably operate on blockchain infrastructure. Raiku provides the missing coordination layer that makes these demanding use cases possible on Solana.

Raiku: Solana’s Coordination Layer

Raiku is not a new blockchain and not a Layer 2. Instead, it acts as a coordination layer between Solana’s validator network, application execution environments, and builders and institutions. This allows applications to use specialized execution logic without changing Solana’s core consensus. Think of Raiku as traffic control for Solana’s execution layer, ensuring transactions are scheduled, coordinated, and executed reliably even under heavy load.

Raiku is like reserved bandwidth; you pay for a guaranteed execution window and the system delivers exactly that.

What Raiku is (and isn’t)

Raiku Is

  • • An execution coordination layer
  • • A blockspace marketplace
  • • Built to work with Solana

Raiku Is Not

  • • A Layer 2
  • • A new blockchain
  • • A validator replacement
