According to The Defiant, the Fogo mainnet has stopped producing blocks for about 46 hours since Saturday afternoon due to an attack on the Fogo Foundation, resulting in 4 million FOGO tokens (approximately 10.3% of the circulating supply) being transferred to the attacker's address. The foundation initially stated that the chain itself was unaffected, but 15 hours later, the network was actively paused, and plans were made to restrict the related addresses through an upgrade. Currently, the Fogo official explorer shows the last block as 718,525,971, and the RPC endpoint returns a 502 error, while the on-chain TVL tracked by DefiLlama has been frozen at $987,000 for three consecutive days.This downtime is attributed to Fogo's validator design: the chain is managed by a council of 7 voting validators, with the foundation staking evenly among 7 operators, allowing for coordination to pause and implement a client-level address blacklist within minutes. On the exchange side, both KuCoin and Gate have disabled FOGO deposits and withdrawals but retained trading, with a 24-hour spot trading volume of approximately $2.3 million. Meanwhile, a Twitter account impersonating the Fogo Foundation, @FcgoFNDN, posted a false compensation voting link, and Fogo officials reminded users to rely only on information from official channels.Fogo is the second network to actively pause over the weekend, following Cronos, which rolled back its state due to an attack on the Tectonic lending protocol. Fogo raised approximately $7 million by selling 2% of its supply through Binance before launching its mainnet in January, with a valuation of $350 million. The foundation has not yet disclosed details of the attack, compensation plans, or a restart timeline.

According to the Ontology blog, its core development team discovered potential security vulnerabilities during routine security checks. Due to a high emphasis on the security and integrity of the mainnet, Ontology has immediately suspended block production on the Ontology mainnet to allow the technical team and validators to conduct a comprehensive security review of the network and related components. Ontology stated that no security incidents have been confirmed at this time, and there are no indications that user assets have been lost or stolen. ONT, ONG, and other on-chain assets are currently assessed to be unaffected; this suspension is a preventive security measure rather than a response to confirmed asset losses or ongoing attacks.During the review period, block production will remain suspended, and on-chain transactions cannot be processed. Users do not need to transfer or take any action regarding their ONT, ONG, and other on-chain assets, but should avoid conducting time-sensitive on-chain transactions until the network officially confirms its restoration. The duration of the suspension has not yet been determined, and the team will prioritize the comprehensiveness of the security review over speed; block production will not resume until the network has been thoroughly assessed and confirmed to be secure. The Ontology team is collaborating with validators and ecosystem partners to address this matter and will update progress through official channels, with a separate announcement to be made before and after the network restoration.

SVM public chain Fogo officially announced that the Fogo mainnet has been temporarily shut down as a precautionary measure due to the detection of unauthorized activity in the past hour.The shutdown aims to prevent further transfer of affected assets. During the downtime, the network will be upgraded to restrict addresses related to the incident. Fogo stated that further updates will be shared after confirming more information and urged users to rely solely on this official channel for updates.

Jeremy Allaire posted on the X platform that StableFX will soon launch on the Arc mainnet. Previously, StableFX had launched on the Arc public testnet.StableFX is an institutional-grade stablecoin forex engine that covers local currency stablecoins in major and emerging markets, supporting near-instant, 24/7 on-demand settlement, using a PvP mechanism, which means funds are either credited to both parties simultaneously or not at all, to reduce capital occupation, and it can connect multiple vetted counterparties through a single access point.

The Supernova upgrade of MultiversX decouples consensus from execution, allowing the network to reach consensus on blocks before processing transactions. Before the upgrade, block production followed a sequential model: proposers selected transactions, executed them locally, and submitted blocks containing the results, while validators had to re-execute the same transactions before voting, making execution part of the consensus critical path. Supernova changes this order: proposers select transactions and directly propose blocks without prior execution; validators can immediately vote once they confirm the proposal complies with protocol rules, while execution occurs asynchronously in the background, with execution results typically referenced and notarized in the next block header, lagging consensus by about one block (approximately 600 milliseconds).To address the validity verification issues brought by decoupling, Supernova introduces a virtual memory pool state that tracks pending nonces, expected balance consumption, and transactions that have been proposed but whose execution results have not yet reached consensus, providing proposers with a forward-looking account view. Meanwhile, the Execution-Result Inclusion Estimator (EIE) limits the number of execution results that can be referenced in a block based on the capacity that the minimum specification node can safely handle; an automatic backpressure mechanism reduces block capacity when execution lags. Supernova has been producing 600-millisecond blocks on the testnet and devnet since August 20, with the mainnet expected to activate on September 10, 2026.

Hyperliquid co-founder Jeff Yan stated that the manual borrowing feature of HyperCore has been launched on the testnet. Currently, all borrowing functions on the mainnet are still limited to the portfolio margin model.The HyperEVM smart contracts can now access HyperCore's lending features through CoreWriter and read-only precompiled contracts.

The ECX plan will be launched in three phases. The Alpha phase is expected to go live near Bitcoin block height 963648, the Beta phase is scheduled for September 20 at block height 967680, and the permanent mainnet is planned to launch on October 31 at block height 973728. The project is driven by Paul Sztorc, founder and head of Layertwo Labs, and developer of Drivechains and BIP-300/301.ECX will replicate the transaction ledger of Bitcoin's designated snapshot and allocate ECX to the majority of Bitcoin holders on a 1:1 basis on the new network. Users who control their private keys through self-custody wallets at the time of the snapshot will directly receive the corresponding assets, while users of exchanges and other custodial institutions will need to wait for the relevant platforms to decide whether to support the fork and distribute ECX. The original BTC will not be exchanged, locked, or transferred. ECX plans to initially launch seven dedicated sidechains: Thunder, Zside, Bitnames, Bitassets, Photon, Truthcoin, and Coinshift. Of the approximately 1.1 million early Bitcoins associated with Satoshi Nakamoto, about 600,000 ECX will continue to be allocated to these addresses, and approximately 500,000 ECX will be converted through special transactions for early investors and development funds, but this will not affect the BTC on the Bitcoin network.

Stablecoin issuer Circle announced that its blockchain network Arc mainnet will officially launch on September 16. Arc is positioned as a financial infrastructure for the global financial market, aimed at supporting related applications and settlement scenarios.According to reports, the Arc testnet has processed over 500 million transactions to date, with nearly 3 million wallet addresses participating. Additionally, more than 100 partners have remained active on the private mainnet. The initial validator group is expected to participate in network operations alongside Circle.Circle stated that it will continue to promote the construction and ecological expansion of Arc as the underlying infrastructure for the financial market.

Solana developer Brennan Watt announced on the X platform that the Solana mainnet has activated the first slot time reduction, with the target decreasing from the current 400 milliseconds to 350 milliseconds, which will officially take effect in the 1020th Epoch.Watt pointed out that some SDK constants (such as DEFAULT_MS_PER_SLOT) have not yet been updated to the new values and will be pushed in subsequent versions. The transition period may affect applications that rely on SDK constants matching the mainnet reality, and developers are advised to manually determine whether the functionality is enabled based on Epoch boundaries when it takes effect. Watt explained that the long-term plan is to put these parameters on-chain for client queries, but currently, to launch the reduction feature as soon as possible, this transition period must be endured.

Uniswap announced that it will complete the deployment when the September Arc mainnet officially goes live, providing developers with deep on-chain liquidity infrastructure to support the construction of DeFi applications such as lending, structured products, LP strategies, and token issuance. Arc is a public chain under Circle, using USDC as the Gas token, and features sub-second deterministic finality.

Lido tweeted that the NEST automated LDO buyback mechanism has been launched on the mainnet. NEST is a rules-based LDO buyback mechanism, where 50% of the surplus will automatically buy LDO through CoW Swap when the DAO's staking income exceeds the baseline of 40 million USD.If the income in a certain period does not meet the baseline, the corresponding gap will be accounted for in subsequent calculations and must be made up by new surplus before purchases can resume. The daily purchase limit is 50,000 USD, and the annual limit is 10 million USD, with all purchased LDO belonging to the DAO.

According to CoinDesk, the privacy blockchain project Miden plans to launch the privacy stablecoin USDCx, which is natively issued on the Miden network based on Circle's xReserve infrastructure, maintaining a 1:1 peg with USDC. When users hold and transfer USDCx, their balances, counterparties, or transaction histories will not be publicly exposed, but selective information disclosure will be supported for compliance needs.The stablecoin is expected to launch in sync with the Miden mainnet, which is targeted to start at the end of this month. Miden views USDCx as the foundation of its "PriFi" privacy finance direction, covering scenarios such as institutional trading, B2B payments, payroll management, and cross-border payments, aiming to address the pain points of achieving both transparency and compliance in institutional finance on public blockchains. Previously, in April last year, it was reported that Miden completed a $25 million seed round of financing, led by a16z Crypto along with Hack VC and 1kx.

The Bitcoin minority fork supporting BIP-110 split at block height 961,632, and after mining only 2 blocks in about 8 hours, it has stagnated, now lagging behind the Bitcoin mainnet by over 80 blocks.This fork inherits the current difficulty of Bitcoin, but only about 2.53% of recent block signals support BIP-110, far below the 55% activation threshold required without a fork. Bitcoin adjusts its difficulty only after mining 2016 blocks, and based on the current hash rate, this chain is expected to take about 350 days to complete its next adjustment.BIP-110 aims to temporarily prohibit writing non-financial data such as images and text in Bitcoin transactions. Michael Saylor stated that about 99.85% of Bitcoin hash power remains on the mainnet; due to both chains being affected by the same transactions, transactions on the minority chain may be replayed to the Bitcoin mainnet.

According to monitoring by the KITE Foundation, its security monitoring system has flagged abnormal KITE token transfer activities on the Ethereum mainnet. The team subsequently initiated an incident response and suspended all KITE token transfers on the Ethereum mainnet, including cross-chain functionality.The affected tokens have been frozen and will not enter the secondary market. The investigation is still ongoing.

Circle announced that its open blockchain network Arc, aimed at the global financial market, will officially launch on the public mainnet on September 16. It is currently operating on a private mainnet and has attracted over 100 institutional and ecosystem participants. BlackRock, DTCC (Depository Trust & Clearing Corporation), Galaxy, Global Payments, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered Bank, Sumitomo Corporation, and Visa will participate as genesis validators for network security and governance.BlackRock plans to deploy its dollar institutional digital liquidity fund BUIDL on Arc, while DTCC is advancing the tokenization and settlement integration with Arc, supporting the tokenization of assets held at DTC to Arc for on-chain settlement based on stablecoins. Circle also plans to launch a supporting application framework, AI tools, and tokenized asset issuance management capabilities on Arc.

According to The Block, Tether's compliant stablecoin USA₮ (USAT) has officially launched on the Celo mainnet, marking its second mainnet deployment after Ethereum. The token is issued by Anchorage Digital Bank and can be natively minted and redeemed on Celo, and can be directly used for on-chain gas payments through Celo's fee abstraction mechanism.USAT launched in January this year, with a current market capitalization of approximately $185 million.

ChianCatcher news, Solana officially announced that the mainnet has launched 100M CU blocks. SIMD-0286 increases the block computing unit limit from 60M to 100M, with a capacity increase of 66%.The official stated that about 1/9 of the blocks were operating close to full capacity during peak on-chain activity in the past year, and 100M CU provides more space for the network. This move is just the first step, and subsequent upgrades such as Alpenglow and 200ms slot time will be promoted.

Fully Homomorphic Encryption (FHE) company Zama CEO Rand Hindi stated on X on Monday that the company has achieved benchmark results of 1,000 confidential transactions per second on GPUs, an increase of about 5,000 times compared to the 0.2 transactions per second demonstrated at ETHcc in 2022. Hindi mentioned that the cost of running an FHE node is approximately $0.000004 per ERC7984 transaction, significantly lower than zero-knowledge proofs, but this comparison has not been independently verified. The benchmark has not yet been activated on any mainnet, is self-reported data from the company, and the testing methods have not been published, with plans to go live by the end of the year.Hindi also set long-term goals: 10,000 tps by 2028 and 100,000 tps by 2030. Zama has been active recently: on July 24, a confidential RFQ exchange product was launched, which within weeks shielded over $121 million USDT on Ethereum, collaborated with Elliptic to enhance compliance screening for confidential transactions, and co-founded the Confidential Token Association with OpenZeppelin and Inco to standardize encrypted ERC-20 tokens. Zama previously completed a $57 million Series B funding round.
