Oh wow, damn. It might be that your particular use case triggers some of its filters (ie sounds too close to cryptography?). It's mostly fine with general code in my experience. Maybe emphasize that it's an academic prototype, rather than a practical system

Solid cryptography solution, but lattice-based, huh?

What does the word "Threshold" actually mean in cryptography? 🏦🔑 In last week's quiz, @RialoHQ asked a fundamental definition question. Do you know the answer? While concept sounds highly technical, its core philosophy is incredibly simple and vital for decentralized security. Defining the Threshold Think of a traditional physical vault that requires multiple keys to open. The "threshold" is the exact line where security meets action. ▫️The Magic Number: It represents the minimum number of independent cryptographic shares (or participants) required to collectively sign a transaction, decrypt data or execute a command. ▫️The Safe Zone: If your system requires 4 out of 7 nodes to authorize an action, your threshold is 4. Any hacker or rogue actor who compromises 1,2 or 3 nodes is left completely powerless. The math simply wont unlock until that fourth piece is presented. Why It Matters for Rialo Traditional Web3 architecture often forces a hard compromise between security and speed. By building native threshold mechanics directly into its frastructure, Rialo eliminates centralized blind spots. No single node holds the master key, and no single point of failure can compromise the network. It provides institutional-grade safety running seamlessly at machine speed. In a world full of digital vulnerabilities, true security means making sure no single person hold the crown alone.👑

Something is shifting, you can feel it. Quantum computing adds a new layer of concern. It will break some cryptography, but not all systems are equally exposed. If you’re unsure about on-chain assets or privacy, take it seriously but it’s not the immediate priority. We’ve been quantum resistant from day one, built for what comes next, not what’s already failing.

Thank this man for digital communication, data compression (ZIP, MP3), coding theory, and cryptography. Claude Shannon’s biggest scientific contribution was the creation of information theory in his 1948 paper “A Mathematical Theory of Communication.” He defined “information” mathematically, introducing the concept of bits (binary digits) as the fundamental unit. He borrowed the term from thermodynamics to describe the uncertainty or information content in a message. Shannon entropy became the foundation of data compression and coding. He proved the Shannon limit (channel capacity theorem): there is a maximum rate (capacity) at which data can be transmitted over a noisy channel with arbitrarily low error, using proper encoding. His framework underlies digital communication, data compression (ZIP, MP3), coding theory, cryptography, the internet, mobile phones, and AI.

Nobody thinks you hold the coins you say you do. Cryptography can’t be bought, auditors can.

Quantum computers will break certain cryptographic protocols, but some will stay safe. Which cryptography is quantum-resistant and which isn't, and why? Watch my explanation

【量子業界】 Keyfactorが10億ドル超の戦略投資を調達　耐量子暗号インフラ拡大へ本格加速 （2026年7月6日 日本時間・The Quantum Insider） 要点： デジタル証明書やPKI（公開鍵基盤）、マシンID管理を手掛けるKeyfactorは、Summit Partners主導による10億ドル超の戦略的成長投資を発表しました。調達資金は製品開発、海外展開、人材採用、戦略的買収に充てられ、AI時代と耐量子暗号（Post-Quantum Cryptography: PQC）への移行を支える「Trust Control Plane」の強化を進めます。既存株主のInsight PartnersとSixth Street Growthも引き続き大株主として参画します。 押さえる数字： ・戦略投資額：10億ドル超（約1,450億円、1ドル約145円換算） ・投資主導：Summit Partners ・既存主要株主：Insight Partners、Sixth Street Growth ・資金用途：製品開発、グローバル展開、人材採用、戦略的買収 ニュース内容： 今回の投資は、量子コンピュータそのものではなく、「量子時代のセキュリティ基盤」への大型投資という点が重要です。 Keyfactorは企業内のデジタル証明書、暗号鍵、マシンIDなどを一元管理するプラットフォームを提供しており、新たなTrust Control Planeでは、それらの可視化・運用・更新を自動化します。量子コンピュータの発展によって現在広く使われる公開鍵暗号が将来的に脅威を受けることが想定されるため、企業は耐量子暗号への移行準備を進める必要があります。Keyfactorは、その移行を支える基盤ソフトウェア企業として存在感を高めています。 また、同社CEOのJordan Rackie氏は、2026年6月に米ホワイトハウスが2030年までの耐量子暗号移行を加速する大統領令を打ち出したことにも触れ、政府政策が市場拡大を後押ししているとの認識を示しました。 業界の読み解き： 量子産業では、量子コンピュータの性能向上だけでなく、「量子コンピュータが実用化された後も社会インフラを安全に運用できること」が重要なテーマになっています。 耐量子暗号は、金融、政府、通信、クラウド、製造業などあらゆるデジタルサービスに関わる共通基盤です。暗号アルゴリズムを新しい方式へ置き換えるだけではなく、企業全体で何百万もの証明書や暗号鍵を把握・更新・管理する仕組みが必要になります。 今回の10億ドル超という大型投資は、市場が「量子計算機そのもの」だけでなく、「量子時代を支えるインフラ企業」にも大きな成長機会を見込んでいることを示す出来事と言えます。量子技術の社会実装は、ハードウェアと同時にセキュリティ基盤の整備が進むことで初めて加速します。 この先の展望： 今後は耐量子暗号への移行が、政府機関だけでなく民間企業にも広がることで、証明書管理や暗号資産管理の重要性はさらに高まる可能性があります。こうした基盤整備が進めば、クラウドサービスやAIシステム、金融インフラ、量子安全通信など幅広い分野で、安全なデジタル基盤への移行が現実味を帯びてきます。量子コンピューティングの普及と並行して、量子時代に対応したサイバーセキュリティ市場も成長局面へ入りつつあることを示すニュースといえるでしょう。 評価： ・業界インパクト：★★★★☆ ・注目度：★★★★☆ ・関連銘柄：IBM 結論： 量子コンピュータの進化は、計算性能だけではなく、それを安全に活用するためのセキュリティ基盤の整備と一体で進みます。今回の大型投資は、耐量子暗号への移行が研究段階から企業の実装フェーズへ近づいていることを示す象徴的な動きとして注目されます。 出典：The Quantum Insider （thequantuminsider.com/2026/0…）

Your response wasn’t clear. Serious systems continue to build auth flows in-house. It gives you better control and you build specifically for your business needs. Unless you’re touching the underlying cryptography, there’s no reason to outsource auth. Or am I missing something?.

My favorite part about doing the @btctkvr podcast is that I learn the story of Bitcoin from the perspective of people who were there since the early days Well, today I will interview the creator & host of the Metzdowd cryptography mailing list – the place where Satoshi Nakamoto first announced Bitcoin on October 31st 2008 His name is Perry E. Metzger and he’s a fascinating individual, with interests ranging from cryptography to open source AI If you like Bitcoin history and want to learn from someone who’s been into computers for 5 decades, tune in at 4 PM EST / 10 PM CET The interview will be livestreamed here on Twitter, as well as on YouTube. Feel free to join the live chat and ask questions!

This week’s theme is compression. Post-quantum timelines moved closer. Bitcoin’s retrofit path got more concrete. Compute demand ran into the grid. 3 signals stood out: 1️⃣ @Microsoft accelerated its quantum-safe roadmap. Microsoft is now targeting a transition of products and services to post-quantum cryptography by 2029, pulling forward the broader transition target from its earlier 2033 full-transition plan. The move came shortly after Washington issued new guidance for federal PQC migration, with agencies directed to prioritize high-impact systems, high-value assets, and sensitive systems for risk reduction by the end of 2030. The roadmap spans TLS 1.3, crypto-agility, key management, code signing, certificate issuance, key protection, and update pipelines. At Microsoft’s scale, this is a system-wide engineering program. For enterprises still treating PQC as a distant migration, the planning window just got tighter. 2️⃣ Bitcoin’s post-quantum work reached the proposal layer. @Blockstream’s Q2 update introduced OP_CHECKSHRINCS, a proposed post-quantum signature opcode for Bitcoin based on a hash-based scheme. The proposal builds on earlier post-quantum signature work demonstrated on Liquid, moving the conversation from sidechain deployment toward something the wider Bitcoin community can evaluate. That is what retrofit work looks like in practice: research, production-sidechain testing, opcode proposals, ecosystem review, and eventual migration. The code may be the cleanest part, moving a live network without breaking trust is the real work. 3️⃣ The US grid put compute on a shorter leash. During the East Coast heatwave, the U.S. Department of @ENERGY authorized PJM, the largest US grid operator, to direct backup generation resources at data centers and other large-load customers as a last resort before or during an Energy Emergency Alert 3. PJM also ordered emergency electricity-reduction measures as demand approached its 20-year record, while spot wholesale prices in parts of the Mid-Atlantic and Dominion zones surged past $2,500 per megawatt-hour. Reuters also reported that data center demand accounted for an estimated $3.8B of PJM’s year-over-year wholesale power cost increase in the first five months of 2026. Compute is becoming part of real-time grid management. Power, cooling, location, backup generation, and demand response now sit inside the compute stack.
