Raiku 🐉

Raiku builds co-located execution for Solana. Blackline runs your strategy on the same hardware as Raiku's custom validator, the machine that builds the block. Working prototype, being developed for client use. Access by invitation.

A London asset manager founded in 1804 put an emerging markets bond strategy on Solana last week. Welcome @Schroders, and nice work @centrifuge. Good timing too, with Breakpoint coming to London on Sunday.

Your Solana transaction didn't land. First suspect? Fees, the RPC, an expired blockhash, or your own code. Be honest.

International Accounting Day. In 1494 Luca Pacioli published the first printed guide to double-entry bookkeeping. Two columns, everything balances. Solana's a ledger too, one hundreds of validators keep in step every few hundred ms. Hats off to the accountants. London, 5 days

RPC accepted ≠ landed. Landed ≠ finalized. Solana marks a signature processed, confirmed, or finalized. Processed can still change on a fork; finalized is the strongest commitment. Track inclusion and confirmation as separate outcomes. solana.com/docs/rpc/http/get…

Gold Sponsor at Breakpoint 2026. 15–17 November, Olympia London. We're on the main staircase, so you'll walk past us at least twice a day. Come and talk about where the block gets built, and how close you can trade to it.

London has been telling people to mind the gap since the late 60s. On Solana the gap is the stretch between your server and the validator building the block. Most of the market is busy shrinking it. In our own leader slots, there isn't one. London, 6 days

National STEM day so it's physics time! Light in fiber does about 200,000 km a second, roughly 5 microseconds per km. Nobody's speeding up glass, so desks pay for shorter cable. This week we show you the machine. In our own leader slots the strategy and validator share the hardware.

Zero Distance: your strategy on the same hardware as Raiku's validator — the machine that builds the block. Only in Raiku's own leader slots. Not across every Solana block. raiku.com

Quant trading is a slightly weighted coin, flipped millions of times. At 200ms a slot, how often you get to flip depends on how close you are to the block.

Blackline, in plain words: trading software on the same hardware as Raiku's own validator. The desk brings its strategy, and the strategy and profits stay theirs.

Honest question for the Solana traders here: where's your bot running right now? Cloud region, rented box near a big validator, a server under the desk, a laptop that never sleeps? No judgement. We're trying to get a feel for how far most strategies sit from the block.

Two weeks of Alpenglow on mainnet. The handoff from towerbft took about 900ms. 446 of 654 validators signed the genesis certificate. Votes stopped being transactions, tx counts dropped and nothing broke. Clean one. Hats off to @anza_xyz and every operator who upgraded.

rkuSOL is now on Jupiter Lend! Thanks to the @JupiterExchange team for making it happen.
