MANTRA Chain Back Online After 30‑Hour Halt Following Cosmos‑EVM Vulnerability Fix
MANTRA Chain back online after 30-hour outage following Cosmos‑EVM fix MANTRA Chain has resumed block production after its developers rolled out a patched client (v8.4.0) to close a vulnerability in the chain’s Cosmos‑EVM module that left the mainnet unable to process transactions for roughly 30 hours. What happened - The network was halted late on Aug. 20 after MANTRA detected an attacker exploiting a vulnerability in an upstream dependency. Developers froze transactions and network endpoints while security teams investigated. - Mainnet remained stopped at block 17,449,398 as teams took a full snapshot and reviewed potential attack paths. - On Aug. 22, after coordinated testing and validator upgrades, block production resumed at about 05:30 UTC using the patched v8.4.0 release. Key technical and security notes - MANTRA traced the issue to its Cosmos‑EVM module and said the activity affected two MANTRA‑managed wallets. The project has not disclosed specifics about what occurred in those addresses, how much value (if any) moved, or the exact upstream component that contained the flaw. - The restart did not require module changes, state migrations, or any rollback — the team says there was no alteration of network state and user balances were unchanged. Token holders were told they did not need to take any action. - The patch was tested first on MANTRA’s DuKong testnet and in an internal environment that replicated mainnet state; repeated upgrade rehearsals were run before validators were signaled to restart. MANTRA‑operated validators were upgraded first, then partner validators, node operators, RPC services and archive nodes to avoid partial‑restart issues. - Public RPC and EVM endpoints came back online after the restart, though explorers and indexers may lag while catching up. DuKong remained offline as engineers continue restoring the public testnet over the following days. Service disruptions - The shutdown froze transfers, staking, bridges and MANTRA‑managed IBC relays; some exchanges paused deposits and withdrawals. MANTRA described the chain as an RWA‑focused Layer 1 and confirmed the outage affected on‑chain activity globally, including U.S. users, but said user balances were not exploited. Context: Cosmos‑EVM and prior vulnerability disclosures - MANTRA added EVM compatibility alongside CosmWasm in September 2025 so developers could deploy Ethereum‑style smart contracts on its RWA network. - The incident comes after Cosmos Labs disclosed a critical Cosmos‑EVM vulnerability (ASA‑2026‑002) in March 2026 involving the ICS20 precompile and nested EVM execution that previously led to an estimated $7 million loss on Saga EVM. Cosmos Labs said a permanent fix landed in Cosmos‑EVM v0.6.0 and identified chains that had patched or mitigated the issue. - MANTRA was among the teams that helped investigate the earlier disclosure, but neither MANTRA nor Cosmos Labs have linked the Aug. 20 incident to that prior ICS20 flaw. MANTRA has said it will publish a technical post‑mortem in the coming days; attribution before that report would be premature. Market reaction and corporate context - The MANTRA token fell roughly 18.5% during the outage, from about $0.005060 to a record low of $0.004126 (CoinGecko), with trading volume jumping nearly 600% to roughly $24 million at the height of market activity. MANTRA has not confirmed whether the price move was caused by the attack. - The chain has institutional ties: Inveniam Capital Partners announced an agreement to acquire MANTRA and affiliates after a $20 million strategic investment in August 2025. MANTRA also is linked to NVNM Chain, a Layer‑2 project for private‑market asset data built on MANTRA. Next steps MANTRA says a complete post‑incident analysis covering the Cosmos‑EVM vulnerability and the network’s response will be released in the coming days. Until that technical report appears, key details — including the attack path, exact upstream component exploited, and any asset movements in the two managed wallets — remain undisclosed.

Solana Cuts Slot Time to 350ms — First Step Toward 200ms and Faster Finality
Solana just shaved more time off its confirmations — and while it doesn't immediately rewrite SOL’s price story, it strengthens the chain’s core product: speed. What changed - Validators running the Agave v4.2 client activated the first of four planned slot-time cuts, trimming Solana’s base slot from 400ms to 350ms. This is the network’s first slot-length reduction since genesis and the opening move in a phased roadmap toward a 200ms slot. - A “slot” is the fixed window in which the current leader validator builds a block. Shorter slots mean transactions reach finality faster — the point at which a transaction can no longer be reversed. - The change relies on previously delivered performance improvements in Turbine (how blocks propagate across the network) and Replay (how validators reprocess blocks). It was proposed as SIMD-469 and formally approved as SIMD-0525. Why it matters technically - Lower latency: 350ms slots make Solana’s confirmations even quicker — it already settled transactions well under a second, far faster than Bitcoin (~10 minutes) and Ethereum (~12 seconds). - Censorship resistance: shorter slots reduce the window that any single leader controls block production. Together with a separate proposal to cut consecutive leader slots, the upgrade limits how long a validator can dominate the pipeline. - Controlled rollout: each slot reduction is gated and flips on in a later epoch (an epoch produces 432,000 slots, roughly 2–3 days). The network can pause the rollout if block-skip rates rise — a built-in safety that signals the timing is too aggressive for current hardware. Market and narrative implications - SOL is trading higher today — around $91, up roughly 4.4% — and well above its June low near $64.55. Short-term indicators show heat (daily RSI ~81, overbought), while the 200-day average remains bearish. - Practically, infrastructure upgrades like this are treated by markets as a “competence” signal rather than an immediate price catalyst. The full 200ms target is still months away, so the direct price impact is limited for now. - Where it can move the needle is narrative and fundamentals: a public, staged march to 200ms strengthens Solana’s “fastest chain” case for developers, funds and builders who weigh throughput and latency when choosing a platform. What to watch next - Each upcoming slot cut (300ms, then down toward 200ms) and the network’s block-skip metrics as new steps flip. - Any concurrent changes to leader slot assignments that tighten censorship defenses. - Broader market drivers — Bitcoin’s recent run and liquidations have lifted many altcoins, including SOL, and will continue to dominate short-term price action. Bottom line This is meaningful infrastructure work that reinforces Solana’s competitive edge on speed and censorship resistance. It’s bullish for the protocol’s technical story, but don’t expect a one-to-one boost to SOL price immediately — the upgrade is a staged, cautious rollout and the market is currently driven more by macro crypto flows than a single performance tweak.

SEC's Reg Crypto Could Let Hundreds of Tokens Shed Securities Status, Galaxy Says
Headline: SEC’s Reg Crypto Could Clear Legal Fog for Hundreds of Tokens, Galaxy Research Says The SEC’s Reg Crypto proposal — published in the Federal Register on Aug. 21 (docket S7-2026-27) — could offer a practical path for many existing tokens to exit “investment contract” status, resolving years of legal uncertainty, according to a new analysis from Galaxy Research. What the safe harbor would do - The proposed “investment contract” safe harbor would let an issuer formally end the securities treatment tied to a token once it has completed (or permanently stopped) the essential managerial work promised to buyers, stopped making further promises, and filed a transition report (Form TR) with the SEC. - Once those conditions are met, the related investment contract would be treated as terminated under the Securities Act and the Exchange Act, while the token could continue to trade without remaining locked to that original contract. - The safe harbor would not cover tokenized stocks, bonds, or hybrids that combine tokens with equity or other securities. Why Galaxy expects an early effect on existing tokens - Galaxy Research estimates the clearest near-term impact will be on tokens already in circulation, not a surge of new public token sales. Alex Thorn, head of firmwide research at Galaxy, said resolving securities-law questions around existing assets could be the first visible result. - The SEC expects roughly 475 issuers a year would file transition reports under the safe harbor, versus about 130 annual offerings under the proposal’s two new fundraising exemptions — a gap suggesting existing projects may use the exit route sooner than new issuers use the fundraising options. Practicalities and costs - Preparing a standalone transition report is estimated by the SEC to require about 30 burden hours on average, including outside professional support. Galaxy says most issuers will likely need legal or compliance help. - Issuers would certify they meet the safe harbor conditions by filing Form TR, but the SEC would retain the ability to challenge those certifications. New fundraising tracks: startup route and Reg A-style tiers - Reg Crypto also proposes two fundraising exemptions: - Startup route: a one-time exemption allowing up to $5 million in covered investment contracts over a maximum four-year period, with public filings at the beginning and end. - Reg A–style route: two tiers — Tier 1 up to $20 million in 12 months; Tier 2 up to $75 million in 12 months. Tier 2 would require audited financials and substantial U.S. ties for organization, management, and assets. - For unaccredited investors, the purchase cap would be 10% of annual income or net worth, whichever is higher. Covered investment contracts sold under these exemptions would not be classified as restricted securities, allowing immediate resale unless a contract explicitly restricts that right. Disclosure tailored to tokens - Reg Crypto would go beyond corporate-style disclosures and require information relevant to digital assets: token supply and release schedules, minting/burning mechanisms, governance and smart contract permissions, source code, ecosystem structure, development promises, and progress updates. - Galaxy notes these disclosures align with the decision drivers token buyers actually use, such as supply controls and smart-contract access, which differ from rights attached to corporate stock. Open questions and limits - The proposal would preempt state registration and qualification requirements for covered primary offerings and some secondary transactions, provided issuers stay current; state antifraud enforcement would remain. - Reg Crypto does not set rules for exchanges, brokers, dealers, or custodians, nor does it decide whether a token leaving investment contract status becomes a commodity regulated by the CFTC. A separate legislative fix — the CLARITY Act — would address statutory allocation of oversight between the SEC and CFTC. - Galaxy warns that an SEC rule can be changed by future commissions and that only Congress can make the clarity permanent — “Reg Crypto could provide meaningful regulatory clarity, but only Congress can make that clarity durable,” Thorn said. Obstacles that could limit fundraising uptake - Some projects may still prefer Rule 506 (Regulation D), which allows uncapped offerings without public SEC qualification or continuing reports, although it does not open public distribution to non-accredited buyers. - Offshore structures common to token projects (foundations handling governance, treasury, tax planning) could block use of the larger Reg Crypto exemption, which requires significant U.S. ties for issuers. The $5 million startup route has looser U.S. presence requirements and may be more accessible for smaller domestic offerings. Political and procedural context - The Senate has scheduled a Sept. 15 procedural test (cloture vote) for the CLARITY Act; the cloture motion requires 60 votes just to begin consideration. - The SEC’s Reg Crypto proposal currently has supporters among commissioners: Chairman Paul Atkins and Commissioners Hester Peirce and Mark Uyeda issued statements backing the plan. The public comment period runs through Oct. 20. What to watch next - Market participants will be watching who files Form TR and how many projects use the safe harbor versus the fundraising exemptions. - Key open questions include how exchanges and the CFTC will react, whether offshore-focused projects can meet U.S. ties tests, and whether Congress will pass (or amend) the CLARITY Act to lock in interagency jurisdiction. Bottom line: Reg Crypto could be the tool that finally unmoors many tokens from long-running securities disputes — but its reach, permanence, and impact will depend on issuer choices, regulator responses, and potential Congressional action.

ビットコイン・マイナーはAI対応のインフラに数十億ドルを投じてきたが、それに対する収益見通しは現時点では比較にならないほど小さい。BlocksBridge Consultingの8月20日の分析によると、公開しているビットコイン・マイナーは2026年上半期に資本的支出として資産に51.1億ドルを投じた一方で、同期間の人工知能(AI)および高性能コンピューティング(HPC)収益は3.412億ドルにとどまった。これは資本支出と、直接報告されたAI/HPC収益の比率が約15対1であることを意味し、新たなデータセンター事業が商業規模に到達するまでにどれほど大規模な立ち上げインフラが必要かを強調している。レポートはAIまたはHPCの収入を開示する9社に焦点を当てた。これらは第2四半期にAI/HPC収益2.058億ドルを創出しており、これは第1四半期から52%の増加だ。これを踏まえると第1四半期の収益は約1.354億ドルで、上半期合計で3.412億ドルとなる。BlocksBridgeは、この比較はAIプロジェクトの直接的なROI(投資収益率)指標ではないと注意している。資本支出の集計には、ハードウェア、物件、設備、その他の生産的資産に対する購入や割当が含まれ、その一部はビットコイン・マイニングを支え続けているためだ。同社は「電力契約や利用可能な土地がマイナーに出発時の優位性を与える可能性はあるが、それらの資産をAI対応の能力に転換するには、変電設備、建物、冷却システム、ネットワーク機器、そして一部のビジネスモデルではGPUが必要になる」と書いている。さらに、これらの案件には先行資金が必要で、工事の進捗、電力の利用可能性、顧客の集中度といった要因が、投資回収の速さに影響する。こうした構図を象徴するのがCore Scientificだ。同社の第2四半期のコロケーション収益は前四半期の7,750万ドルから1億3,670万ドルに増えた一方で、当該期間の資本的支出は7億9,750万ドルに達した。7月中旬までにCoreは、同社が能力として437メガワットを請求していると述べ、また、最終的に5つのサイトで約530MWをカバーし得るAMDとの契約を開示した。会社はこれらの契約が15年間で潜在的なベース収益として140億ドル超をもたらすと説明している。TeraWulfも、継続型のデータセンター収入へとシフトしている。2026年の第1四半期において、HPCのリース収入が同社のビットコイン・マイニング収益を上回り、規制当局への提出資料では、HPCが四半期収益の大部分を占めるようになったと示されている。とはいえ、その成長は建設マイルストーンの達成、テナントの確保、契約されたコンピュート用ハードウェアの受領に依存している。9社を超えた見方では、BlocksBridgeはより広い15社規模のコホートを調査し、2026年の最新の報告期間で資本的支出として307億ドルをAIデータセンター関連企業とともに投じていたことを見出した。これは、2025年に全社で記録された215.3億ドルから42.6%増だ。ただし、この集計額には開発段階の異なる企業が混在しており、収益性の直接的な尺度というよりは、業界レベルの投資スナップショットとして読むべきものだ。他のマイナーは、戦略的な資産移動を通じて移行を資金面で支えている。Marathon Digital(MARA)は、デジタル・インフラへの重点を再確認する中で、第1四半期にビットコインを15億ドル売却した。HIVEはより小規模なアプローチを追求してきた。同社のHPC収益は2026会計年度に94%増の1,950万ドルとなったが、ビットコイン・マイニングは依然として主要な収益源だ。このシフトは投資商品にも波及している。CoinSharesはWGMIの名称を「CoinShares Bitcoin Mining and Digital Power ETF」に変更し、対象となる銘柄の範囲を拡大した。そこにはマイナー、データセンター運営企業、AI半導体企業、電力生産者、先端コンピューティング企業が含まれる。積極運用の同ファンドは8月18日時点で29のポジションを保有し、約2.256億ドルの資産を持っている。純資産の少なくとも80%を適格企業に投資する必要があり、ビットコインは直接保有しない。今後の主な試金石は単純だ。マイナーは約束した能力を予定通りに提供できるのか、有力で信用力のあるテナントを獲得し、維持できるのか、そして契約された電力を継続的な収益ストリームへと転換できるのか。現時点では、新しいAI/HPC収益の基盤は成長しているが、移行に投じられた巨大な資本に比べると依然として小さい。続きを読む:undefined/news
新しいロイター/イプソスの世論調査では、多くのアメリカ人が、トランプ大統領が在任中に仮想通貨の収益を得ることに反対していることがわかり、同大統領の家族の事業活動と大統領としての職務が重なることへの国民の不安が高まっていることを示している。オンライン調査は8月14日〜17日に実施され、8月19日に公表された。調査では、米国の成人1,166人に質問し、誤差は約±3ポイントだった。回答者の63%は、トランプ家が同大統領が職務に就いている間に仮想通貨から利益を得るのは不適切だと述べた。一方で32%は適切だと見ており、残りは回答を控えた。見解は党派で大きく割れた。共和党員の約69%は仮想通貨での得を適切と考えたのに対し、民主党員の92%は不適切だとした。無党派層の約2/3は「トランプの事業への関心が職務上の判断に影響している」と答え、全体では回答者の69%が「事業上のつながりが大統領の意思決定に影響している」と述べた。今回の調査は、トランプ大統領の年次の財務開示が6月に公表されたことに続く。ロイターの分析では、その提出書類には2025年に仮想通貨関連のベンチャーに結び付いた収入として14億ドル超が記載されていたという。この数字は、報告された収入が事業体を通じて流れてきたことを反映している(個人が保有する仮想通貨の現在の市場価値ではない)もので、個人の純利益の計算ではない。ロイターの内訳によれば、World Liberty FinancialやOfficial TRUMPメメコインといったプロジェクトからの仮想通貨関連収入は1,000百万ドル超で、そのうちWorld Liberty Financialに結び付くものは約8億ドル(トークンの販売で520百万ドル超、事業持分の売却で250百万ドル超)だった。またTRUMPトークンに関連するライセンス収入として約6億3500万ドルが報告されていた。ブロックチェーン研究者らも、トランプ関連の事業体が取引に関連する収益を引き続き集めていた一方で、多くのトークン購入者が大きな損失を投稿していたことを指摘している。今回の調査結果は世論を測るものであり、違法行為を申し立てるものではない。ホワイトハウスは利益相反がないとして繰り返し否定している。ホワイトハウスの報道官アンナ・ケリーはロイターに対し、「利益相反はない。大統領はアメリカ国民の最善の利益のためにのみ行動する」と述べた。トランプ氏も同様に、自身の投資は独立して管理されており、日々の家族の事業運営には関与していないと述べている。政治的背景も重要だ。議会ではデジタル資産に関するより明確な連邦ルールを作る法案が議論されており、提案されている倫理規定――場合によっては当局者やその家族を特定の仮想通貨活動から制限する――が大きな論点になっている。広範な仮想通貨市場ルールを求める支持者は新たな規制が必要だと主張する一方、批判側は、デジタル資産の事業と金銭的なつながりを持つ選挙で選ばれた公職者を対象により厳格なセーフガードが必要だと求めている。規制の動きは並行して進んでいる。8月14日、World Liberty Financialは、全国の信託銀行としてWorld Liberty Trust Companyを設立するために、通貨監督庁(OCC)から条件付き承認を受けた。条件付き承認では、会社が業務開始の前に追加の規制条件を満たす必要がある。議会の監督、今後の財務開示、そしてWorld Libertyが提案する信託銀行に付随する条件は、現在の取り決めが大統領の公務上の責務と家族の事業利益との分離を十分に行えているかどうかの次の試金石になる可能性が高い。現時点では、ロイター/イプソスの世論調査は、多くのアメリカ人がこうした懸念が解消されたという点に依然として確信を持てないことを示している。続きを読む: undefined/news
