What is Raiku?
Raiku is an execution layer that makes transaction execution on Solana predictable by turning blockspace into a schedulable, market-priced resource.
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.
- When traffic is light → everything moves smoothly
- When traffic spikes → cars slow down, pile up, or miss exits
Today, applications on Solana:
- Can’t always guarantee their transactions will land
- Struggle during congestion
- Are forced to add workarounds instead of relying on the network
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
