Rakurai

Rakurai develops high-throughput, low-latency validator infrastructure for the Solana network and offers staking products to SOL holders. Its software aims to produce larger blocks with greater compute-unit capacity, lower-latency execution and faster transaction scheduling, so that validators capture more high-fee transactions within each slot. The resulting block rewards are shared with stakers and node operators, which the company frames as a way to increase capital efficiency for validators while keeping infrastructure permissionless.

The staker-facing product line includes a liquid or reward-bearing staking token, raiSOL, with features such as auto-compounding, and a promotional boosted block-reward campaign at the start of 2026. For node operators, Rakurai markets transaction-dense block packing and throughput gains intended to keep validators above the cluster average, alongside multi-signature protections and third-party auditing of its software. The company's stated roadmap centers on bridging centralized and decentralized finance by providing high quality of service, ultra-low latency and guaranteed block space for what it describes as an internet capital markets era.

Business model

Rakurai supplies validator client software and staking services on Solana, sharing block rewards between the operator and delegating stakers.

Traction

The company states it has exceeded 8.5% of Solana's total network stake and builds blocks 50% larger than the cluster average, with readiness for 100 million compute-unit block sizes.

Latest developments

At the start of 2026 Rakurai advertised a +25% boosted block rewards offer on raiSOL and outlined a roadmap for a CeFi-to-DeFi bridge with guaranteed block space and ultra-low latency.
