@adust09 Ethereumへの貢献の第一歩として頑張ります！
ありがとうございます！

[涼介 @RKaga92084]

I’m going to Devcon 8 in India 🇮🇳

Huge thanks to @geodelabs for supporting my participation.

I hope this will be the first leap toward my journey to the Ethereum Foundation.

See you at Devcon!

これ毎月やってくれるのか　ありがたい

The September all-Protocol update is out. Glamsterdam heads to Sepolia on Oct 6, both Hegotá headliners are on devnets, and the PQ roadmap is taking concrete shape. Plus faster block propagation and autoresearch. Highlights in the thread below. 👇 https://t.co/apO2oPLZKd

@adust09 @EFDevcon 何が起こってるんですか！？早くハウスいきます！

[涼介 @RKaga92084]

@grandchildrice ここに答えが書いてあった… 師匠

[Ethereum Foundation @ethereumfndn]

The Protocol Cluster has published two new posts:

Hegotá EIP Opinion Post and Tier List evaluates and grades all 62 EIPs proposed for Hegotá, providing the cluster’s first unified tier list for a network upgrade

Current and Emerging Priorities covers commitments and research arcs, anchored on a quantum-resistant Ethereum L1 by Dec. 2029

Offered as one input to Hegotá scoping, roughly 60 researchers, engineers, and individual domain experts across all 9 teams in the Protocol Cluster contributed to the Hegotá tier list, providing 397 tier grades before discussing contested items live.

The plan, commitments, and shared set of cluster-wide priorities covered in the companion post provide the context behind the final tier grades.

The Protocol cluster will host a Reddit AMA on r/ethereum on September 16 at 2pm UTC to talk through these priorities, the Hegotá tier list, and anything else on your mind.

Ethereumの全体像をまとめた記事を書きました。プログラミングやシステム構築をしていてEthereumをほとんどわからない人向けの視点です。

自分の理解を言語化したもので、校正なく書き途中ですが、書き疲れしてしまったので一旦公開です。

ETHOnline 2026参加します！優勝して、次の道に繋げるのが目標です！

[涼介 @RKaga92084]

@adust09 俺の想像とだいぶちかい…

[涼介 @RKaga92084]

自分のwebsiteを作りました。EFに入るまでの勉強や研究を公開していこうと思います！

発想の転換があったのか。binary fieldは他の素数体babybear とかの方がstarkに使われてるイメージあって飛ばそうかと思っていたけど勉強しとこう。

Goodbye, Poseidon!

An epic 8-year, 8-figure rabbit hole in post-quantum cryptography reaches its dream conclusion. The Ethereum Foundation is abandoning Poseidon for L1, pivoting to SHA or BLAKE. This milestone unlocks ultimate security for lean Ethereum and foreshadows a golden era of hash-based cryptography.

Since 2018, the Ethereum Foundation has invested in magic cryptographic bricks, so-called "SNARK-friendly hashes". In 2019, Poseidon was born. It held strong and became the dominant SNARK-friendly hash, securing billions via zkrollups and zkVMs.

In a stunning reversal, breakthrough SNARK designs show that SNARK-friendly hashes aren't necessary after all. Off-the-shelf traditional hash functions like SHA2 and BLAKE2s can now match Poseidon in a SNARK. In hindsight the key was not SNARK-friendly hashes, but hash-friendly SNARKs.

The secret is doing maths over the smallest prime number: 2. So-called "binary fields" natively speak the language of bits, aligning with the boolean operations inside traditional hashes. This is a stark departure from "prime fields", where awkward large-prime arithmetic makes bit manipulation painfully expensive.

We're talking sci-fi cryptography. 1M traditional hash calls proven per second, on a laptop. Just 100x overhead vs native CPU boolean compute. Nobody predicted such performance, not even the handful of binary-field visionaries. Hat tip to the research geniuses: Jim and Ben with Binius in 2023; Ron, Benedikt and William with Flock in June.

With SHA2, the lean aesthetic of minimal assumptions reaches its climax. The EF's principled stance on pure hash-based cryptography has aged like fine wine. We now enjoy foundations the world can trust for decades and centuries, foundations worthy of the dream of an internet of value.

Speed of deployment is a secondary win. There's no longer a need to wait years for Poseidon cryptanalysis to bake. Emile and Thomas from the EF post-quantum team are moving at breakneck speed with binary fields. The strawmap now points to a production-grade leanVM in 2027, with CL, DL, EL deployments in 2028.

As AI becomes exceptional at cryptanalysis, the contrarian bet to avoid riskier structures like lattices and isogenies is visibly paying off. The past weeks have been brutal. Lattice-based "HAWK" and isogeny-based "SQIsign", both signature schemes in NIST's Round 3, have suffered blows. Sources I trust say more blood is coming.

On AI, the open autoresearch trend kicked off by ECDSA[.]fail is spreading fast, with amazing outcomes from zk[.]golf and SNARK[.]fast. Days ago SNARK[.]fast crossed 1.8M BLAKE3/sec proven on an M3 Max. Stay tuned for fresh autoresearch challenges dropping tomorrow.

Also tomorrow: Ethproofs call #10, dedicated to binary fields. Possibly the most noteworthy Ethproofs call yet. Experts leading the charge will present the future of hash-based SNARKs at 2pm UTC. What an incredible time to be alive. To witness history, DM me for a calendar invite :)

Today I can confidently claim that hash-based cryptography has won out for blockchain post-quantum signatures. SNARK succinctness compresses arbitrarily many signatures into one small proof per block. SNARK flexibility yields k-of-n threshold signatures, complex multisigs, and more.

Ultimate security. Uncompromising performance. Full programmability.

Believe in something. Believe in hashes.

例えば、goldilocksいう有限体の設定を書いた後に、新しくmersenne31のコードを書く時はプロンプトでこういう設定で乗算はこうなるとか書いておくと理解しながら直ぐコードを追加できて感動してました！

[涼介 @RKaga92084]

昔bitcoinやray tracerの実装を1から書いているとき、理解した後の作業が多かったのに対し、今はAIでここも同じふうに書けるとか、実装手順を明記することで理解しながらコードを書く手間が省けて学習速度が飛躍的に上昇していると感じています！

Rustで型を書くのは数学の証明に似ている気がする。このコードを書くにはこういう性質を満たす型であればいいっていうのを意識していて思った。
前提 => 結果
が
型 => 型　になってるイメージだがうまくまだ言葉に表せない。

[涼介 @RKaga92084]

例えばarkworksのFp 構造体のジェネリクスを見て、MontConfig がなぜ存在するのかが分かった

自分は元々研究者になりたく、最近はethereumに魅せられてその道を目指すようになりました。全体像は何となくわかるが、すぐ壁に直面することが多く、基盤を一から実装することで理解を深めたくこのロードマップを作りました。
