According to crypto journalist Eleanor Terrett, sources say that a bipartisan group of minority senators in the U.S. Senate held discussions last night regarding the CLARITY Act, attempting to push the Democrats to make concessions on at least two outstanding issues, but ultimately failed to reach an agreement.Senator Cynthia Lummis stated that both sides had reached consensus on "99% of the content" of the bill and expressed hope that the Democrats would continue to address the remaining issues after the bill passes committee review; otherwise, if a similar incident to FTX occurs in the future, "they can only blame themselves."Reports indicate that Democratic Senators Adam Schiff and Ruben Gallego have been pushing for a compromise on the ethical standards and conflict of interest clauses involving the president's family before the committee review, making it one of the conditions for supporting the bill.Additionally, some Democratic lawmakers have raised concerns about provisions related to the Blockchain Regulatory Certainty Act (BRCA). This provision aims to prohibit lawsuits against non-custodial software developers based on money transfer laws.Sources say that both sides have made substantial progress on ethical and conflict of interest issues, but disagreements over amendments to the BRCA ultimately led to the breakdown of negotiations. The market currently widely expects that this committee review will show clear partisanship.

The cryptocurrency market is strengthening in sync with global stock indices, and risk assets continue to show an upward trend. As of this morning, BTC has firmly stood above the key support level of $81,000 and is showing a sustained upward trend.Meanwhile, major global stock indices are performing strongly, with several core indices reaching historical highs this week. According to data from the Gate platform, SPX500 (S&P 500 Index) reached a peak of $7,314.55 during trading, setting a new historical high, and is currently reported at $7,274.36; NAS100 (Nasdaq 100 Index) is currently reported at $28,211.46, with a 24-hour increase of 1.73%; JPN225 (Nikkei 225 Index) is currently reported at $387.33, with a 24-hour increase of 2.21%, indicating a continued warming of global risk appetite.Against this backdrop, the inter-market asset correlation has further strengthened. Gate has launched the world's first index perpetual contracts, currently offering 15 trading pairs that cover major global stock indices and volatility indices, fully supporting USDT settlement and 24/7 continuous trading. At the same time, the platform has expanded to include various traditional financial assets such as stocks, metals, foreign exchange, and commodities, continuously building an integrated derivatives trading system that coordinates cryptocurrency assets with TradFi.

According to FinanceFeeds, Alex Thorn, the research director of Galaxy Digital, stated that as advancements in quantum computing hardware accelerate, the Bitcoin community is shifting from decentralized debates to forming a preliminary consensus on quantum threats. The core direction is to gradually introduce post-quantum cryptography (PQC) through soft forks, achieving an upgrade of the address system and long-term security assurance.The report points out that the current Bitcoin signature mechanism, which uses the Elliptic Curve Digital Signature Algorithm, can theoretically be cracked by Shor's algorithm. Approximately 2 million BTC from early p2pkh addresses are at risk because their public keys have been exposed, facing the potential risk of "collecting first and decrypting later." The community tends to promote a "migration window" mechanism to guide users in transferring their assets to new quantum-resistant addresses, and after a multi-year grace period, to implement freezing or destruction of untransferred assets to prevent large-scale market impacts in extreme situations. Additionally, the consensus includes enhancing "cryptographic agility," which allows protocols to switch signature algorithms without interrupting the network.The current proposal leans towards a dual-signature mechanism that uses ECDSA and PQC (such as Dilithium) in parallel, ensuring security redundancy while facilitating a smooth transition. Analysts believe that this approach transforms the quantum threat from a "black swan event" into a manageable technological upgrade, helping to solidify Bitcoin's security foundation as a long-term store of value asset.

Researcher Dan Robinson from Paradigm proposed a new scheme called PACT (Verifiable Address Controlled Timestamp), aimed at protecting long-dormant bitcoins, including Satoshi's early addresses, from future quantum computing attacks.This mechanism allows users to prove their control over an address through a timestamp without the need to transfer assets or expose on-chain behavior. Once future quantum attacks occur, assets can be recovered in a quantum-resistant version of the Bitcoin network based on that proof. Compared to mandatory migration schemes (like BIP-361), PACT avoids the privacy exposure issues caused by actively transferring assets, providing long-term holders with a more flexible preemptive protection path.

According to Cointelegraph, the cross-chain protocol ZetaChain disclosed that the security issues involved in its recent approximately $334,000 vulnerability attack event had been reported in advance by researchers in the bug bounty program but were deemed "expected behavior" by the project team at that time and were not addressed.According to the official incident review, this attack originated from a combination of three design flaws that initially appeared to be independent and low-risk: the Gateway contract allowed anyone to send any cross-chain instructions; the receiving end could execute calls on almost any contract, and the blacklist restrictions were too narrow; some wallets retained unlimited approvals for a long time without being cleared. The attacker ultimately combined these flaws to instruct the Gateway to transfer tokens directly to their controlled address, thus completing the asset transfer.ZetaChain stated that this attack involved 9 transactions across four chains: Ethereum, Arbitrum, Base, and BSC, with the stolen funds all coming from wallets controlled by ZetaChain, and user funds were not affected. The official noted that the attack showed clear premeditation. The attacker funded the wallet through Tornado Cash three days before the attack and deployed a dedicated Drainer contract in advance, while also implementing an Address Poisoning attack.Currently, ZetaChain has begun pushing repair patches to the mainnet nodes, permanently disabling the arbitrary call function and changing the unlimited approval mechanism in the deposit process to "exact amount authorization."

The Solana Foundation stated that its core development team Anza has reached an agreement with Firedancer, a subsidiary of Jump Crypto, on a potential post-quantum solution, planning to introduce a new digital signature scheme called Falcon.Although the threat of quantum computing is not expected to materialize for several years, Solana has developed a phased upgrade roadmap. This plan includes ongoing research into Falcon and other alternatives, introducing post-quantum solutions for new wallets when necessary, and ultimately completing the migration of existing wallets. Currently, the quantum-resistant primitive Winternitz Vault, developed by Blueshift, has been running on Solana for over two years. The Solana Foundation stated that the network's high-speed, low-latency design can accommodate such solutions, and the migration is not expected to have a significant impact on performance.

Investors including Pantera Capital Management are pushing the UK Bitcoin reserve company Satsuma to sell its $50 million Bitcoin reserve.Satsuma shifted to an "AI-driven" Bitcoin reserve strategy in August 2025, successfully raising £164 million (approximately $221 million) through convertible loan notes, led by ParaFi Capital, with participation from Pantera, Digital Currency Group (DCG), Kraken, Arrington Capital, and others. It is reported that Satsuma confirmed that some shareholders "requested a return of capital," but did not disclose the identities of the specific shareholders. Satsuma's Executive Chairman Ranald McGregor-Smith stated in an email that the company is exploring options to facilitate these requests while protecting the interests of all shareholders.

According to Bloomberg, the cryptocurrency venture capital fund Pantera Capital Management is urging the London-listed company Satsuma Technology Plc to sell its remaining approximately $50 million in Bitcoin and return the funds to shareholders.Satsuma has confirmed that some shareholders have requested a return of funds, and the company is evaluating related proposals. Additionally, sources revealed that the shareholders are also demanding a change in management; currently, Satsuma's CEO Henry Elder and CFO Andrew Smith have resigned. Earlier this month, the company announced it would cut costs and disclosed the purchase of Bitcoin worth £1.4 million.

The FCA stated that it will review the relevant correspondence and respond.

According to Cointelegraph, Telegram CEO Pavel Durov called WhatsApp's end-to-end encryption a "huge consumer fraud." He pointed out that about 95% of private messages ultimately end up stored in unencrypted backups on Apple and Google servers.Durov believes that this situation puts users' privacy at risk. Although WhatsApp claims that its message transmission process uses end-to-end encryption, the actual backup mechanism fails to ensure the complete encryption of user information. This statement has raised industry concerns about the privacy protection measures of mainstream messaging applications.
