Corvus Labs researcher Andrei Vacariu published an investigation alleging that Everstake — a Solana validator group led by former Grayscale founding general manager David Kinitsky — sells a private, real-time feed of pending transactions to quant traders for $4,000 a month, with entry-level access starting at 10 SOL (~$1,000) per month. Vacariu traced payouts through a revenue-sharing wallet to entities including Staking Facilities (allegedly over 950 SOL since July), Prostaking (over 200 SOL), RockawayX, and Stake.org, and said Everstake salespeople are recruiting additional validator node operators into the arrangement.

The allegation targets the market-structure integrity of Solana, one of the largest smart-contract networks, suggesting that MEV extraction there has been privatized into a paid club rather than eliminated by the network's mempool-less design. If accurate, ordinary DeFi traders on Solana are systematically exposed to front-running and sandwich attacks with no ability to opt out, and staking delegators may be unknowingly supporting validators that monetize their order flow.

Solana has no public mempool, so most transactions travel directly to the validator scheduled to build the next block; paying customers can reportedly run Everstake's software to mirror incoming traffic before a block exists and insert trades around retail orders. Everstake, which runs one of Solana's larger validators with roughly 7.4 million SOL delegated to it and is an association of 39 validators staking over 50 million SOL collectively, denies encouraging front-running or sandwiching and says it uses filtering mechanisms specifically to prevent that activity; the service is described as repackaging an institutional 'stake-weighted quality of service' tier through a product called Blockspace, available to validators with over 15,000 SOL staked.

The Federal Open Market Committee voted unanimously (12-0) to raise the fed funds target range by 25 basis points to 3.75%-4.00%, the first rate hike since July 2023, with the quarterly dot plot now showing a median projection of 4.1% at the end of 2026 versus 3.8% in June. Chair Kevin Warsh said at his post-meeting press conference that the economy "has indeed strengthened" but that "inflation is the problem."

This ends a more than three-year easing/on-hold cycle and signals that the Warsh-led Fed is willing to tighten even amid political pressure from President Donald Trump for lower rates, resetting expectations for the entire 2026 policy path. Higher policy rates raise the cost of borrowing, lift yields on risk-free Treasuries, and typically drain liquidity from speculative assets, so the move re-prices the macro backdrop that crypto and equity markets trade against.

The decision was widely anticipated and largely priced in, which explains why bitcoin spiked to roughly $76,500 five minutes after the release and then gave the gains back within half an hour, stabilizing near $75,500-$75,700; the median dot now implies one more hike in 2026, and Warsh declined to comment on Trump's reaction. The FOMC statement cited solid economic activity, resilient domestic spending, elevated inflation and geopolitical uncertainty, and reiterated that the committee "will deliver price stability."

OpenAI published a framework for tracking, investigating and disclosing model misalignment, released alongside six reports documenting unexpected or concerning model behavior. The framework describes how employees report suspected misalignment incidents internally to senior safety and alignment leaders, who then decide whether a deeper investigation is warranted.

A leading frontier lab formalizing how it detects and discloses misalignment sets an operational precedent that other labs and regulators are likely to reference, shifting incident transparency from ad hoc blog posts toward a repeatable process. It also gives external researchers and enterprise buyers a clearer channel for learning when deployed or pre-deployment models behave in unintended ways.

OpenAI states that its misalignment disclosure practices need to expand for the current phase of model capabilities, and that there is not yet a clear standard for reporting misalignment during training, evaluation and deployment. The framework therefore covers the whole lifecycle — training, evaluation and deployment — rather than only incidents observed after a model ships.

CoinShares data shows publicly traded Bitcoin miners have signed more than $100 billion in AI and HPC contracts, yet they are generating only about $1.1 billion in annualized revenue and are billing roughly 550 MW out of more than 4 GW under contract. Ten of the 12 miners tracked by CoinShares gained between 70% and 195% in the second quarter even before that revenue arrived.

Miners with contracted AI/HPC capacity trade at about 12.9x enterprise value to next-12-month sales versus 3.7x for those without, a premium resting on future deployment rather than current cash flow. That makes the sector's AI pivot highly sensitive to construction timelines, grid interconnection delays, and financing conditions.

Retrofitting a Bitcoin mining site into an AI facility costs an estimated $8 million to $15 million per megawatt, versus roughly $700,000 to $1 million per megawatt for Bitcoin mining infrastructure, though AI infrastructure yields about $1.5 million in annualized profit per megawatt against roughly $500,000 for Bitcoin mining. CoinShares counted at least 225 data-center moratoriums or restrictions across 30 US states, 151 still in force, alongside a national grid interconnection queue of about 2,600 GW where projects completed in 2025 waited a median of more than five years.

Solana activated its new Transaction V1 format on Sept. 15, raising the maximum serialized transaction size from 1,232 bytes to 4,096 bytes — more than a threefold increase — while the Anza-developed Agave client moves the network's slot time from 300ms to 250ms, expected to take effect around 05:01 UTC on Sept. 18 when epoch 1037 begins. Both changes land as the network handles record transaction volumes and rising activity across stablecoins, apps, and tokenized equities.

The combination of larger transactions and shorter slots expands both what developers can build in a single atomic transaction and how quickly the network responds, strengthening Solana's position in the high-throughput layer-1 race against Ethereum and other chains. It also raises the operational bar for validators, wallets, and exchanges, since tighter slot windows demand more reliable block production and propagation, and services must be able to parse the new format as adoption grows.

V1 is introduced through SIMD-0385, can reference up to 64 accounts directly, moves compute-unit limits and fee information inside the transaction message rather than separate instructions, and removes Address Lookup Tables; legacy and v0 transactions still work, so migration is optional. The upgrade does not by itself make transactions faster or cheaper, and shorter slots do not automatically double capacity because the work allowed per slot is adjusted as slot times shrink.

A hacker group calling itself "iamnotavillain" is demanding 6,000 monero (XMR), worth about $3 million, from Revolut within 24 hours, threatening to sell stolen customer data to other criminal groups if the payment is not made, according to the Financial Times. At least 680 Revolut customer accounts were affected, and the group sent the FT a 60-second screen recording appearing to show passports, driving licences, KYC photos and transaction histories.

This is a confirmed data breach at a major digital bank with more than 80 million customers, exposing identity documents and transaction histories for users the attackers specifically selected for their large crypto holdings. It highlights how KYC and identity data held by regulated fintechs can become a targeted asset, and it reinforces monero's role as the preferred settlement rail for extortion demands.

The attackers told the FT they used blockchain analysis to identify Revolut accounts holding significant crypto assets, and they said no negotiations had taken place at the time of publication. The breach reportedly stemmed from attackers impersonating government officials and sending information requests that passed Revolut's verification checks; Revolut says it blocked the address used, notified the relevant government agency, law enforcement and regulators, and that its systems and customer funds were unaffected.

Payward, the parent company of Kraken, plans to offer onchain perpetual futures to US clients on the Hyperliquid platform, aiming to become the first registered US exchange to deploy markets on the Hyperliquid protocol. The plan leverages Payward's $550 million acquisition of Bitnomial, which would deploy, administer, clear and settle the proposed markets, while NinjaTrader Clearing would carry approved customer accounts.

This would be one of the first concrete attempts to connect fully CFTC-licensed US derivatives infrastructure with a decentralized onchain venue, potentially opening US access to perpetual futures that have largely been available only through offshore platforms. If it proceeds, it signals a shift in how regulated US exchanges view onchain market structure and could pressure other US venues to build similar hybrid offerings.

The proposed markets are described as permissioned, meaning access would be gated rather than open to any Hyperliquid user, and the structure is split between Bitnomial handling deployment and clearing/settlement and NinjaTrader Clearing carrying approved customer accounts. Bitnomial is notable for holding all three CFTC-issued licenses required to operate a full-stack US crypto derivatives business, a status acquired through Payward's roughly $550 million deal.

Aave Labs is proposing an Aave V4 RWA Hub on Avalanche that would allow institutions to borrow Tether's USA₮ stablecoin against tokenized collateral. Both the hub itself and the USA₮ listing are set to go before an Aave DAO governance vote, and no launch date has been given.

It would push DeFi's largest lending protocol deeper into institutional, real-world-asset credit by pairing tokenized Treasuries, private credit and real estate with a regulated dollar stablecoin. If approved, it also marks a notable expansion of Tether's USA₮ footprint beyond pure payments and into onchain collateralized lending.

The hub is framed as an Aave V4 deployment, meaning it depends on the upcoming V4 architecture rather than the current V3 codebase, and reported collateral types include tokenized Treasuries, private credit and real estate. USA₮ is Tether's federally oriented, dollar-backed stablecoin designed for institutional use in the United States, which is the source of dollar liquidity for the market.

Bitcoin Core 32, the next major release of Bitcoin's reference implementation, has entered final testing ahead of an October release, changing how nodes estimate transaction fees and process blocks while fixing a wallet flaw that could let an authenticated user execute commands on a node. Four commands used to create partially signed transactions will also begin using the newer PSBT version 2 format by default.

Bitcoin Core is the reference implementation for the largest cryptocurrency by market capitalization, so a release candidate touching fee estimation, block validation and wallet security directly affects the node operators, miners and wallet developers who run the network's most widely deployed software. Because these changes are scheduled to land in October, operators have a window to test compatibility before the stable release propagates across the network.

The wallet fix addresses a flaw that could allow an authenticated user to execute commands on a node, and the release also switches four partially-signed-transaction commands to PSBT version 2 by default — a format commonly passed between wallet software and hardware signing devices. Fee estimation in Bitcoin Core is derived from observing unconfirmed transactions and how long they take to confirm, so estimate quality depends on a node having been running and collecting data for some time.

Xiaomi has published a public, continuously updating dashboard at mimo.xiaomi.com/rl that visualizes the post-training of its MiMo 2.6 model, showing reinforcement learning and distillation running in real time. The page is a live interactive view of the training process rather than a one-off paper or static benchmark release.

Post-training — the RL and distillation stage that runs after pretraining — is now where most frontier capability gains are produced, and most labs keep it entirely closed, so exposing a live view of it is an unusual transparency move. It also reinforces MiMo's positioning as a low-cost coding model, which is the trait users in the discussion actually care about.

The dashboard is closer to an interactive demo than a paradigm-shifting breakthrough, and one commenter cites MiMo-v2.5-Pro scoring about 19% on DeepSWE 1.1 versus 70% for Fable, 69% for Kimi K3 and 74% for Astra at maximum effort. The series' selling point therefore remains usable quality per unit of cost rather than the top of the benchmark leaderboard.

The UK Financial Conduct Authority published final perimeter guidance clarifying which crypto activities require authorization under its incoming regime, covering issuing qualifying stablecoins, operating crypto trading platforms, dealing and arranging transactions, safeguarding cryptoassets and arranging crypto staking. Applications open on September 30, 2026 and run to a February 28, 2027 deadline, with the full regime taking effect on October 25, 2027.

The guidance draws the regulatory perimeter for the UK's crypto market, forcing both domestic and overseas firms that serve UK retail customers to apply for authorization or a variation of permission rather than relying on existing registrations. Because there is no overseas persons exclusion for dealing, arranging or safeguarding, the rules shape which firms can keep serving UK clients and at what compliance cost.

Existing registrations and permissions will not automatically convert under the new regime, and firms that miss the February 28, 2027 deadline lose the transitional cover that allows them to keep operating while their application is assessed. The FCA also plans to consult later this year on further changes to its perimeter guidance, alongside separate work on tokenized assets including a consultation on whether some tokenized gold products should be exempt from UK fund rules.
