According to SolanaFloor, Jump Crypto's Firedancer team will stop supporting the Solana transitional validator client Frankendancer after Alpenglow is activated on the Solana mainnet, with the upgrade expected to go live in October with v4.3.The team stated that the decision was made due to the maintenance and security burden, and they will subsequently focus resources on the complete Firedancer client.

The blockchain project Quantus announced the launch of its PoW mainnet using post-quantum cryptography, which incorporates the ML-DSA-65 and ML-DSA-87 digital signature mechanisms. The total supply limit of the native token QTC is 21 million, and PoW mining has been open since the launch.

The core development team of Solana, Anza, posted on platform X stating that the mainnet Beta transaction V1 will begin activation at epoch 1035, expected around September 15 at 1:20 UTC.The ecosystem team indicated that more time is needed to test and integrate V1 support; V1 is currently live on the development network for integration testing. The computational budget in V1 is set through new transaction configuration settings; the computational budget instructions are still usable in traditional transactions and V0 transactions, but will not take effect in V1; application developers should check the impact of related changes on their applications even if they do not plan to send V1 transactions.

Quantus founder and CEO Yuvi Lightman posted on X that the anti-quantum blockchain Quantus mainnet will go live on September 9 (Wednesday). The only way to acquire tokens at the launch is through mining, and liquidity and tradability will be available a few weeks later.The team has merged Immunefi security work into the public code repository and completed all fixes from the audit competition. The chain supports ML-DSA-65 and ML-DSA-87, binding each signature to its context according to FIPS 204 standards, failing and closing multi-signature transactions that cannot be decoded, and strengthening the network stack to resist denial-of-service attacks. The team has completed a full-process drill on the global rehearsal mainnet covering the Americas, Asia, Europe, and Australia, producing signed binaries through an automated pipeline, deploying multi-region bootnodes and dedicated RPC nodes as infrastructure as code, and reducing indexer memory usage from over 90% to about 26%.In addition, Quantus has launched a registration page, completed a website redesign, Keystone hardware wallet supports multiple accounts, and released CLI v2.1.3 and miner v4.0.2. Quantum & Privacy Day will be co-hosted with NEAR in Singapore on October 8, coinciding with Token2049.

Scroll Governance Forum posted that the team will recently apply AI extensively in operations and product development. Previously, core chain operations required over 20 engineers, but now it is completed by fewer dedicated engineers in conjunction with AI agents, while maintaining existing usability and security standards. The team believes that blockchain can provide a trusted coordination layer to define and execute rules, and ZK can help agents interact with credentials, private data, and computations without exposing underlying information.The team is building an interconnected product stack: Compass is an iOS application that can access the large models and functions provided by the Compass API, and includes VPN and eSIM; Compass API is the AI routing infrastructure, connecting over 30 large models; CENO provides a trust layer through ZK, protecting credentials, agent context, and privacy computations; USX is used for payments and settlements; SCR continues to coordinate governance; the Scroll network serves as a trust and coordination layer. CENO has reached out to over 30 potential clients, of which 12 are participating in proof of concept testing.The team plans to gradually transform Scroll from a general public chain into a dedicated network centered around Compass and the AI product stack, with an overall transition expected to take about nine months. According to the current plan, SCR will migrate to the Ethereum mainnet to maintain accessibility and liquidity, with supply and token economics remaining unchanged, and will continue to serve as a governance token. This post is only a progress update, not an official proposal or vote, and further proposals regarding the network transformation and matters requiring DAO approval will be made separately.

The cultural signal trading platform Noise announced that the testnet will close on Friday, September 11 at 9 AM (Eastern Time), and the mainnet is about to launch. Noise was founded on the idea that cultural insights should have economic value, and the mainnet will transform this idea into a market where users can curate and trade cultural signals and earn rewards by discovering important content in advance.Credits purchased during the testnet will receive equivalent rewards on the mainnet, only the purchased Credits are eligible; reward Credits, earned Credits, and testnet trading balances will not transfer. Noise thanks users who participated in trading, curation, and providing feedback, stating that they helped shape the product and build the first community. Details about the launch and some surprises will be announced soon.

Cobo co-founder and CEO Shen Yu recalled that he has a deep shadow over ZEC. When ZEC's mainnet launched in 2016, BitMEX set the price ceiling at 10 BTC, which also became the historical high point for ZEC.He stated that shortly after starting to mine on the night of the launch, the transformer of the GPU mining farm was struck by lightning, and since then, ZEC has not appeared in his personal wallet again.

According to Fractal Bitcoin's latest tweet, Fractal Bitcoin completed its first halving at block height 2,100,000, and the FIP-102 proposal was officially activated. According to the official announcement, network nodes and indexing services operated smoothly after the halving.This upgrade marks the official activation of the FIP-102 proposal, and the distribution of FB will expand from the Fractal network to the Bitcoin mainnet, providing a direct path for a broader Bitcoin user base to access FB. After the activation of FIP-102, the actual block reward on the Fractal side further decreases to 6.25 FB, with an additional 6.25 FB issuance budget being redirected to the Bitcoin mainnet. FIP-102 does not increase the total supply of FB, and the block rewards for joint mining, free mining, and indexing mining on the Fractal side will still be distributed at a ratio of 1:1:1. The specific distribution mechanism for the Bitcoin mainnet will be clarified in the subsequent FIP-103, with the goal of launching in the first quarter of 2027.

According to CryptoBriefing, the Bitcoin wallet Xverse has launched a joint Bitcoin staking service, allowing users to pair sBTC with STX tokens to participate in the Stacks PoX-5 locking period. During the staking period, Bitcoin remains on the Bitcoin mainnet and is controlled by the users, without the need for cross-chain or wrapping. This feature requires an upgrade to the Xverse v2.9 version wallet.Registration will close on September 9 or when the quota is used up. Staking rewards are expected to be distributed starting September 10 (Bitcoin block 966350, corresponding to Stacks' 143rd period). Institutions such as UTXO (a subsidiary of Nakamoto Inc.), HashKey Cloud, and 21shares have joined as anchor participants. Previously, Xverse managed approximately 152 million STX in non-custodial staking.

Harmony has released two proposals to comprehensively shut down the mainnet launched in 2019, migrate the native token ONE to Ethereum, and shift towards an AI video "mashup economy" business. The team stated that the threats posed by national-level attackers and AI entities are the reasons for proposing the network shutdown plan.The migration plan proposes to take a snapshot of user wallets, staking delegations, validator rewards, smart contracts, and tokens within centralized exchanges at the last block of the network, airdropping new ONE to the same wallet addresses on Ethereum, with holders not needing to actively claim; delegated stakes and unclaimed rewards will be airdropped to their respective governance vaults. The total supply of ONE and the issuance rate will remain unchanged, with newly issued tokens intended for the new business and feedback from governors being considered.Multi-signature wallets, liquidity pools, and on-chain applications cannot be migrated. The team urges users to exit all smart contracts by September 10, 2026, and plans to publicly disclose token contracts, snapshot calculations, and airdrop scripts for auditing. Validators can stop running nodes starting from September 10 at 22:00 Beijing time. The team plans to compensate for the difference in issuance rewards between node shutdown and the final block of the network, establishing a one-time compensation pool of $1.372 million, to be paid in four quarters to validators and their delegators who timely shut down, sign agreements, retain stakes, and serve as governors of the new project.The new business will open up prompts and materials for users to create secondary content, with AI entities expanding video stories, and will recruit operators responsible for video generation, distribution, and content review. Harmony plans to subsidize GPU hardware in the first year and promote demand for video generation, with operators required to stake tokens to earn rewards based on service online time. The team plans to help operators generate up to $1 million in total revenue in the first year, provided they meet staking and online rate requirements; promoters can initially earn a 30% ongoing commission from each $10 monthly subscription they recommend. Both proposals are non-binding and the plans may still be adjusted.

HyperliquidNews posted on the X platform that the HyperCore manual lending feature has been launched on the mainnet.

Anza stated that the reduction in Solana token rent has gone live on the mainnet Beta, and proposal SIMD-0437 Step 1 has been activated at epoch 1028.This step reduces the required lamports per byte from 6960 to 6333; subsequent functionality gates will be activated after checking the growth status at the current rent level, ultimately reducing to 696 gradually.

OpenSea will add support on the first day of the Arc mainnet launch (September 16).

AEGIS X (XDAO) announced that it will officially launch its mainnet tomorrow (September 3), and the project will fully enter the ecological operation and global market expansion phase.Previously, the AEGIS X Genesis Reserve Council's global co-construction phase has been completed, with a cumulative co-construction scale reaching 31,656,800 USD.AEGIS X uses USD1 as the core value settlement asset, building an ecosystem around USD1 × AI × DeFi, covering application scenarios such as stablecoin liquidity, on-chain payments, DAO collaborative governance, and AI Agent, promoting more on-chain applications and users to enter the USD1 ecosystem.

Fogo's official announcement states that the Fogo mainnet has been restarted and is operating normally. A total of 400 million FOGO tokens were stolen in this incident, of which 237 million have been recovered and permanently removed from the total supply.The official statement indicates that they are working with centralized exchanges and law enforcement to continue recovering the remaining affected assets. The investigation is still ongoing, and further information will be released through this official channel; please rely solely on updates from this channel.

The first on-chain game launched by FUNVERSE, FUN LONGINUS, will officially go live on the Anubis Chain mainnet on September 1, 2026, at 10:00 UTC (UTC+8 18:00). FUN LONGINUS originates from a hackathon and is an Eastern martial arts chain game designed for the Anubis GameFi ecosystem. It constructs on-chain gameplay around martial arts elements such as the Jianghu, arena, mentorship, Jiazi salary, leader's order, and Huaze artifacts, and is structured competitively based on the twenty-four solar terms.Each match features 24 different addresses participating together, with each player entering the arena using fLGNS. The execution of the match, determination of results, and final settlement are all completed by smart contracts, ultimately producing one leader. Match records, reward distribution, mentorship relationships, and players' Jianghu resumes are all stored on-chain. FUN LONGINUS completed the collective forging of heroes on August 18, 2026, and based on the market price at the time of publication, this collective forging is valued at over 1.4 million USD. The launch of the mainnet marks the game's transition from the hackathon prototype, public testing, and collective forging phase to the official on-chain game operation phase.

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.
