これ、よくある勘違いなのだけど、ブロックチェーンが破壊されているのではなくて、中央集権状態になっているブローカー側の管理方法や組織内の運用がハックされて、そこに付け込まれるのです。 つまり、ブロックチェーンの構造そのものが破壊されるのではなく、組織体制の隙間が狙われているんです。 – at Chuo-ku, Tokyo
こういうニュース見て不思議なのは、暗号資産ってブロックチェーンで安全という謳い文句をよく聞くのに、こういう流出事件がちょいちょい発生するのはなぜ? エコシステム全体を見ると全然安全じゃないということ?

Some further clarity on Binance’s claim that customer funds are safe: The assets were drained from one of its hot wallets, which Binance controlled and is the legal owner of. What does that mean? Generally, when you deposit crypto on an exchange, the exchange becomes the owner and gives you a claim on their assets. Retail customer assets are generally accounted for in an omnibus account with all other retail customer assets, and customers have a claim on a pro rata share. A spokesperson confirmed this to Crypto in America and said the assets were technically Binance’s funds, and represented customers’ ownership claims for crypto on the exchange. Binance holds crypto in its wallets and credits customers’ accounts with the assets bought on their behalf. Binance says it is replacing the stolen assets so customers’ account balances and values remain unchanged. Had Binance not had sufficient funds to account for the stolen assets, some customers may have had their recovery reduced, or received a “haircut.” The exchange says it has reserved more than $6.34 billion in company funds to cover the incident.
🚨NEW: Lots of people are asking: “Binance just got hacked for $6 billion. How can they say funds are safe?” According to a Binance spokesperson, customer funds were not affected. The money drained came from one of the exchange’s own hot wallets. Binance says most customer funds are held in cold wallets and moved to hot wallets only when users make withdrawals. “Most of what we earn from day-to-day operations is held in crypto assets. We have kept a lot of them in the company, and reinvested them — into the business, and into security. Because we believe in crypto, and in the long-term value of this industry,” the spokesman said. “That is precisely why we are able to absorb a loss of this size, immediately, with our own money.”

クリプトどこに置いたらいいんだーって言ってる人の大半は何もビビらずに今まで通りの管理を継続してるに違いないよ。 公式から買ってデバイス弄られた痕跡がなければ基本的には最も安全な部類の管理方法がハードウェアウォレットによるセルフカストディだから。 それに日本人でハードウェアウォレットの資産が抜かれたという投稿は一度も見かけてない。 全部茶番でしかないのよ。 安全 をどうやって担保するかよくわかってない人の一部が被害を受け、ちゃんと自分で何をすべきか理解してる人はノーダメージ。

Binanceの件、2026年10月29日に約63億ドル(約1兆円)相当が流出したと報じられています。 なのに、このタイミングでBitcoinや暗号通貨を売ったり、不安になる人がいますが、実はこれ、まったく逆なんです。 では、なぜ逆なのかということを、講義では何度となく伝えていますが、一度だけXでサクッと長文ポストしておきます。 不安や心配がある方は、最後までじっくり読んでいただきたい内容なので、時間がない方は保存して後で熟読いただけたら嬉しいです。 では、いきます。 まず本題に入る前に、大前提として知っておかないと本題の意味がわからなくなる可能性がある、大切なことを先にお伝えします。 それは、お金には経済学上3つの定義があるということです。 どういうことかと言うと、次の3つを備えていないとお金はお金でない!とされていまふ。 それが「価値の保存」「価値の尺度」「交換の媒介」です。 まず、価値の保存っていうのは、皆さんが働いて得たモノや、何かと何かを交換して得たモノの価値を保存できるのかということ。 硬貨や紙幣は、それが可能とされています。 次に、価値の尺度ですが、皆さんが持つモノの価値はどれくらいあるのかを測れるものかどうかということ。 硬貨や紙幣は、それが可能とされています。 最後に、交換の媒介ですが、これはそのモノが使う際に便利かどうかということ。飲み屋さんに入り支払う媒体として、旬の柿を100個持っていくのは重いしかさばるし大変です。でも、硬貨は細かく分けられるし、紙幣は軽い。 硬貨や紙幣は、それが可能とされています。 この様に、3つを備えているのが、私たちが日々使っている法定通貨が「お金」だと言われる所以です。 でもここで、「ん?法定通貨って、2つしか備わっていないですよね!?」と思えた方は、分かっている方です。 そうです。法定通貨は国により毎年毎週毎時間のように、価値を希薄化させられているからです。 よって、かなりシンプルに言うと、経済学上においては、法定通貨はお金として十分な役割を果たせていないということになるんです。 ちなみに、日本の法定通貨の数はざっくりと現金と預金に分けられており、この合計を「M2」と言ったりします。 では、このM2の数ですが、日本はこの10年で何倍になったかご存知でしょうか。 30年前と比べると約2.4倍も増えており、直近のたった10年でも約1.4倍も増えているんです。 これがどういうことかと言うと、10年前に貯金していた100万円の価値は、お金の量で測ると約27%も減っているんです。 10年前に100万円で買えたものが、モノは同じなのに今では買えなくなっているということであって、お金の価値が27%減っているということなんです。 私はBitcoinに出会って、お金というそもそもの概念に向き合い始めた時、M2という指標を知り思いましたね、 「法定通貨ってやばいよな」と。 だから私は、資産の中心をBitcoinやその他のモノ(株やゴールドや時計や服やカバン等、価値が薄まりにくい種類)に変えたわけです。 こうすると、よく言われるのが「危なくないですか?不便じゃないですか?」という質問です。 はい、不便じゃないです。 何故なら、日本という国は物々交換するには非常に優れたサービスが沢山あるからです。 間違わないでほしいのは、モノには法定通貨も含まれています。何故なら、私にとって法定通貨は、交換媒体としては優れた「モノ」という位置づけだからです。 では、ここから本題に入ります。 まず法定通貨には、価値の保存という備えが中長期的には無いということが、この時点では伝わったかと思います。っと、願っています。 っで、Binanceからの流出です。 今回の様なケースは、 うっ、文字数制限にかかりそうなので、続きは後ほどポストします。 続きを読んでくれる方は👍️
Binance's initial investigation suggests that the security incident may involve a compromised DevOps engineer’s laptop, which allowed an attacker to gain access to a service container and submit unauthorized withdrawal transactions. We have found no evidence of any wallet private key leak. We will share a detailed technical post-mortem once the investigation is complete and the facts are fully verified. The estimated total impact sits at around $6.3B. We have worked with blockchain partners to freeze affected assets, with ~$3 billion frozen on-chain so far. Binance will cover all losses from the SAFU fund and the company’s funds. User funds are safe. We will also publish an updated Proof of Reserves once the remediation is complete. As an immediate precaution, Binance has: - temporarily suspended deposits and withdrawals while security checks are completed; - revoked the affected address authorisation; - engaged law enforcement and blockchain intelligence partners to trace and recover funds. Our teams are working around the clock to resolve this issue safely and thoroughly. We are working closely with our law enforcement partners to confirm the identity of these criminals and bring them to justice. Please rely only on official Binance channels for updates. Please feel free to contact Binance Customer Support if you have any further questions. binance.com/en/support/annou…

Saw a few discussions about size of hack, why impact to bitcoin price is small, etc. 👇 $6.3 billion is the biggest in USD terms, but not in BTC terms. MtGox was 650,000 BTC! Other important numbers to consider: % of bitcoin (in relation to BTC total supply), ie, market impact. MtGox is big there again at 5%+. Number of users impacted, and % of user assets impacted. MtGox (the largest CEX at the time) and FTX (not small) were all near 100% of users and their asseets. Most important: Who is impacted? Does the platform cover it all? (only one victim), as in recent two CEX cases and Binance. Obviously, still a major disaster for the industry, Binance (and me). It hurts, but we survive. Most importantly, we protect our users.

One of the largest crypto exchanges gets hacked for $6 billion and bitcoin sold off less than 5%? Bullish.

流出した瞬間に資産を凍結するために、世界的に取引所等の間でメッセージできるホットラインを作った方がいいよ、って5-6年位前から言ってるだけど、作られているのかな。 今回のバイナンスで分かるように、直ぐに世界的に連絡できる体制を作っておかないと、直ぐに凍結できない資産に換金されて凍結できなくなるよ。

Binance has committed its own balance sheet to making customers whole. I expect it to deliver. Our industry will learn from this incident, strengthen security, and emerge stronger and more resilient.
Binance has begun recovering affected assets for users and continues to work with law enforcement, issuers, blockchain intelligence firms and industry partners to trace, freeze and recover additional funds. The company has already publicly committed to cover losses through company funds in the prior announcement. Binance has already reserved over $6.34B of company funds to cover this incident. $5B of these funds are already held in the exact token assets that were impacted. We are completing the purchase of the remaining amount by buying token assets through market channels and OTC channels. We are doing this to match the format of the remaining token assets and address any asset shortfalls. This step can take longer because some tokens may have low liquidity and OTC settlement also takes time. We will share more progress as soon as we can. These figures do not include frozen or protected assets, which remain subject to ongoing recovery and verification. Currently, $3bn has been frozen, with thanks to our industry partners. We are working with partners and law enforcement to recover the frozen assets.We will continue to use company resources to cover confirmed shortfall and will provide further verified updates as recovery efforts progress. Ultimately, all user funds will be verified publicly through our Proof of Reserves. We will weather this storm. Thank you for the support.

Trust Binance Having worked there, I know how fast this team moves in a crisis. Freezing funds, covering losses with SAFU, pausing deposits and withdrawals, working with law enforcement, and promising a full post mortem plus updated Proof of Reserves. Fast and transparent But I want to use this moment to talk about something more practical. Crypto has more security risks than most people think Exchanges can get attacked Phishing links, fake airdrops, fake support. They show up after every big event Contracts you approved months ago may still have access to your funds Saving your seed phrase as a screenshot or sending it to yourself leaves a door open Your own laptop and phone, every extension you installed, every file you opened, can be an entry point So how do you protect yourself? Here are my own habits Split your funds. Keep only what you trade on exchanges, the rest in cold wallets Turn on withdrawal whitelists. Use an authenticator app for 2FA, not SMS Keep your trading device clean. No random extensions, no random files Review your wallet approvals regularly and revoke what you don’t use Write your seed phrase on paper. Never put it online Only trust official channels. Anyone who DMs you about compensation, unfreezing or verification, block them Platforms can cover you once. Your habits are what keep your money safe

UPDATE: 🚨 Binance co-CEO Richard Teng says only the exchange’s own hot wallet was affected, not customer funds, with the vast majority of user assets held in cold wallets untouched by the incident. He adds that withdrawals are on track to resume within 40 hours, with a full Proof of Reserves report by Monday.
An update on the security incident.
