The privacy coin project Monero has released the graphical wallet software GUI version 0.18.5 "Fluorine Fermi". This update is a recommended upgrade version, mainly containing a large number of bug fixes and functionality optimizations.Key highlights of this update include: migrating the P2Pool installation path to LocalAppData on Windows systems, fixing boundary case issues in URI parsing, prohibiting the creation of offline transactions in long payment ID scenarios, escaping untrusted text in QR code scanning to enhance security, upgrading P2Pool to v4.15, and multiple detail bug fixes and stability improvements.Monero's official team stated that this version has been open-sourced on GitHub, and users can download the upgrade through official channels to obtain the latest security fixes and stability improvements.

According to Cointelegraph, a recent study by TRM Labs shows that despite mainstream cryptocurrency exchanges delisting privacy coins, the activity of Monero remains stable. Research data indicates that transaction usage in 2024 and 2025 is still higher than levels before 2022.TRM Labs noted in its analysis of market trends and underlying network infrastructure that demand has not waned even after many large trading platforms removed or restricted the token due to traceability issues. In 2024, mainstream platforms, including Binance and Kraken, have successively delisted or gradually phased out Monero for compliance reasons. This year, Dubai's financial regulatory authority has prohibited licensed platforms in the Dubai International Financial Centre from listing Monero, Zcash, and other privacy coins, further increasing the pressure.The findings also reveal that Bitcoin remains the preferred currency for real-world ransomware payments. Ransomware operators typically request Monero and sometimes even offer discounts, but victims still tend to pay with Bitcoin. However, the dark web market seems to be evolving in the opposite direction. Researchers found that among new markets launched in 2025, 48% only support Monero, a significant increase compared to previous years.

According to CoinGecko data, the market capitalization of Monero (XMR) has surpassed 10 billion USD, currently reaching 10,745,315,844 USD, setting a new record. The current circulating supply of XMR tokens is 18,446,744, with a 24-hour trading volume hitting 382,607,691 USD.Additionally, according to Coinglass data, the total open interest for XMR contracts across the network has exceeded 200 million USD, also setting a historical high, with a 24-hour open interest increase of 60.07%.

Monero price rose above $567 on Sunday, setting a new all-time high. This increase continues the trend that began at the end of last year, when the privacy token demonstrated stronger resilience than the overall cryptocurrency market.Although Monero has broken through the 2017 bull market cycle high after eight years, Ryan McMillin, Chief Investment Officer of Merkle Tree Capital, stated that the concentration of liquidity due to privacy coins primarily trading on offshore exchanges could lead to fragmented price discovery and amplify volatility, making investors wary of short-term price manipulation risks.

According to Coinmarketcap data, the performance of the top 100 cryptocurrencies by market capitalization is as follows, with the top five gainers: Uniswap (UNI) up 6.21%, current price $7.83; Monero (XMR) up 5.39%, current price $418.2; Bitcoin Cash (BCH) up 3.8%, current price $503.47; MemeCore (M) up 3.51%, current price $2.16; Cosmos (ATOM) up 2.7%, current price $2.85.The top five losers: Dash (DASH) down 10.98%, current price $83.44; Decred (DCR) down 8.6%, current price $33.79; Pump.fun (PUMP) down 8.39%, current price $0.003098; Telcoin (TEL) down 7.78%, current price $0.006382; Story (IP) down 6.68%, current price $2.76.

According to CoinDesk, the privacy-focused cryptocurrency Zcash (ZEC) has surpassed the long-dominant Monero (XMR) in market capitalization, which may signify a power shift in the privacy coin sector. ZEC's market cap first exceeded XMR last Friday, remaining above its predecessor for several hours after a nearly 50% increase in the previous seven days.Throughout the weekend, ZEC maintained its lead, with its market cap reaching as high as $7.2 billion, while XMR hovered around $6.3 billion. Recently, both have had market caps of approximately $6.4 billion. Zcash was launched in 2016, while Monero was created in 2014.The biggest difference between the two lies in their privacy mechanisms: Zcash employs an optional privacy mode, allowing users to choose between transparent or encrypted (shielded) transactions; Monero has all transactions encrypted by default, lacking any choice. This flexibility makes Zcash more readily accepted by traders and institutions, especially those looking to balance privacy with compliance. In contrast, Monero has been delisted from several mainstream trading platforms due to anti-money laundering (AML) and know your customer (KYC) issues.

ChainCatcher news, according to Cryptopolitan, the privacy blockchain Monero has released an important upgrade named CLI v0.18.4.3 "Fluorine Fermi" to enhance protection against spy nodes.In the Monero community, the term "spy nodes" refers to malicious nodes, their affiliated groups, or botnets that can correlate IP addresses with transaction information, effectively undermining the privacy guarantees of the blockchain. The "Fermi" update addresses this issue by implementing an improved node selection algorithm that reduces the likelihood of users connecting to multiple nodes within the same IP subnet, a common strategy used by spy nodes.It prevents users from connecting to large clusters of suspicious IP addresses, guiding them towards safer nodes. The "Fermi" update also changes the way messages are sent and received, making it extremely difficult for spies to track the delivery path of messages. This helps Monero's messaging service avoid these suspicious delivery agents.

ChainCatcher news, as disclosed by Slow Mist's Yu Xian on X platform, Monero has been attacked again, experiencing an 18-block reorganization. In response, Yu Xian stated: "If no one in the Monero community takes the issue of block reorganization seriously, then this sword of Damocles will always hang over Monero... It may not necessarily lead to a double-spend attack, but the capability is there... and it doesn't have to strictly exceed 51% of the hash rate..."

ChainCatcher news, according to Coinmarketcap data, the performance of the top 100 cryptocurrencies by market capitalization is as follows, with the top five gainers: MemeCore (M) up 37.8%, current price $1.38; Pump.fun (PUMP) up 11.98%, current price $0.004312; Four (FORM) up 2.08%, current price $3.67; Mantle (MNT) up 1.17%, current price $1.13; Monero (XMR) up 0.66%, current price $268.44.The top five losers: World Liberty Financial (WLFI) down 20.83%, current price $0.1745; Pyth Network (PYTH) down 8.11%, current price $0.148; Pudgy Penguins (PENGU) down 7.21%, current price $0.02863; Ethena (ENA) down 7.11%, current price $0.6781; SPX6900 (SPX) down 7.07%, current price $1.08.

ChainCatcher news, according to the official announcement, Kraken has suspended deposits for Monero (XMR) as a security precaution because a single mining pool has been detected to have gained over 50% of the total hash rate of the network. This concentration of hash power may pose a potential risk to the integrity of the network. However, withdrawal and trading functions remain open, and the deposit function will be restored after confirming network security.

ChainCatcher news, according to the official announcement, Qubic has achieved over 51% hash rate control on the Monero network, resulting in the reorganization of 6 blocks and 60 blocks becoming orphaned. Preliminary reports indicate that within two hours, Qubic mined 80% of the total Monero blocks.During this period, approximately 750 XMR and 7 million XTM were mined. The unsold Tari from the previous round, combined with 7 million XTM, resulted in the destruction of a total of 17.2 billion QUBIC, with an average price of about 3,200 QUBIC per billion, equivalent to approximately $55,000. Computors and miners collectively received 62.2 billion QUBIC in rewards, valued at around $200,000.The network's peak hash rate reached 2.71 GH/s, accounting for 52% of the global Monero hash rate. A total of 5,506 Monero blocks were mined. Data shows that Qubic's current earnings for miners are nearly four times that of Monero. The 51% Monero experiment is still ongoing.

ChainCatcher news, according to the evaluation by Slow Mist founder Yu Xian, the Monero 51% attack incident has raised many doubts in the community about whether it is truly a 51% attack in the real sense, but there is no doubt about the reorganization of blocks (such as 6 blocks). Qubic mining pool claims to control 51% of the hash power, but many community members believe it controls about 33% of the hash power. This debate is not easy to verify, and to truly prove a 51% attack, a double-spend attack test must be initiated.Previous reports indicated that IOTA co-founder Sergey Ivancheglo's project Qubic quickly accumulated a large amount of Monero hash power through the "useful proof of work (uPoW)" mechanism. On August 12, Qubic briefly controlled 52.72% of the Monero network's hash rate (approximately 3.01 GH/s). Once it exceeds 51%, Qubic can reject blocks from other mining pools, leading to chain reorganization, double spending, or transaction censorship. The Monero community has launched resistance and defense actions, while Qubic claims this move is a technical demonstration, not a malicious attack.

ChainCatcher news, Slow Mist Yu Xian posted on social media, "The Qubic mining pool completed this 51% attack verification on Monero using economic incentive game theory (I believe the starting point was not malicious), leveraging $300 million (market cap of $QUBIC) to move $5 billion (market cap of Monero)."

ChainCatcher message, Qubic responded on social media regarding the Monero (XMR) 51% attack incident, stating, "The Monero (XMR) experiment is proceeding smoothly as planned, and everything will be revealed in due time."

ChainCatcher news, Slow Mist founder Yu Xian tweeted that the 51% attack on Monero seems to have been successful. The Qubic mining pool can now theoretically rewrite the blockchain, enabling double spending and reviewing any transactions. The cost of the attack is high, and it is still uncertain what the economic gain for the attacker is. Relevant platforms are advised to be aware of potential threats and stay vigilant.Ledger CTO Charles Guillemet tweeted that Monero appears to be experiencing a successful 51% attack. The Qubic mining pool has been accumulating hash power for months and now controls most of the network's hash power. A significant chain reorganization was detected this morning. With its current hash power, Qubic can rewrite the blockchain, implement double spending, and review any transactions. The estimated cost to maintain this attack could be as high as $75 million per day.
