I pivoted mid-hackathon and built the first dark pool for Solana perps. Veil Dark Pool: encrypt your order, submit a commitment hash on-chain, solver matches privately, settles on Drift / Jupiter / Phoenix. No one sees your side, price, or size until after execution.

The scarce talent is engineers who can read both the rail (Reth, Revm, ExEx) AND the protocol layer — and ship apps that span both. That's the gap RethLab closes — line-by-line walks through the actual production source, then 9 working apps. rethlab.fabrknt.com

Stablecoins are the base currency of DeFi. Owning the stablecoin payment rail = owning the future DeFi onramp. Today: @Stripe / @Tempo abstract crypto away to onboard TradFi. Tomorrow: lending, swap, perps layer on top. #DeFi #stablecoins

The thing nobody's saying about the Rust EVM stack: It's not winning on share. Geth still runs ~50% of mainnet. Reth is ~7-12%. It's winning on where the new capital and distribution are landing. #Rust #Ethereum

ボディ打ちって相当な勇気がいるんです。 相手の懐に潜り込む瞬間、自分のガードは下がり、顔面は完全に無防備に。 カウンターを食らえば一撃で終わるリスクを背負って、内臓を叩きにいく。 あの恐怖心に打ち勝って踏み込む、肉を斬らせて骨を断つ覚悟。 井上尚弥の凄さは、あの一歩に詰まってる。

I like Bitcoin, Ethereum, and Solana. What is wrong with that? I avoid trashing protocols for petty reasons; none are perfect and each has strengths. Critiques often stem from outdated info. Without looking at others properly, I can't see the challenges in my own, which is key.

Every serious new chain runs on Rust — @HyperliquidX, @tempo, Base — all on @paradigm's Reth/Revm. The engineers who ship infrastructure there have read the source. RethLab teaches it, line by line. 92 free lessons, EN + JA. youtu.be/_KsEPoLnJR4 rethlab.fabrknt.com

@matthuang's thesis: the future is purpose-built #EVM L1s. @tempo for payments. @HyperliquidX for perps. Both run on Reth + Revm — @paradigm's #Rust stack. RethLab teaches that stack, line by line. For engineers building the next one. rethlab.fabrknt.com

@ysksdr @leomarudesu 仲間うちの取り組みであれば何でも称賛してしまいがちな風潮の中で、違うと思うことをハッキリと発言される大木さんはすごい、尊敬。

英雄は堕ち、システムは進化する。次に歴史を刻むのは、人間か、それともコードか。

人間は間違う。だが、台帳（Ledger）は永遠に真実を刻み続ける。
