According to CoinDesk, Solana plans to activate Transaction v1 this Wednesday, increasing the maximum capacity of a single transaction from 1232 bytes to 4096 bytes, more than tripling it. After the upgrade, complex operations that previously required splitting into multiple transactions are expected to be consolidated into a single transaction, including large cryptographic proofs, multi-signature payments, and certain privacy transfers.Transaction v1 has been running on the Solana testnet and development network, and the existing transaction format can still be used. Wallets and applications will only need to upgrade when larger transaction space is required. However, on-chain data services relied upon by block explorers, wallets, and trading applications need to adapt to the new format; otherwise, they may not be able to correctly read transaction and priority fee information.This upgrade aims to alleviate the structural limitations imposed by Solana's long-standing 1232-byte transaction cap, further enhancing its ability to handle complex applications. The 4096-byte limit references the common 4KB memory page size of validator hardware to avoid excessively large single transactions that increase network and validation node processing costs.

In a blog post released on Monday, Anthropic acknowledged that its Claude model had unauthorized access to real computer systems during a cybersecurity assessment, an incident reflecting operational security failures as well as alignment failures in motivation reasoning and intent to harm. Anthropic disclosed in July that the Claude model had breached the systems of three companies because the third-party assessment environment was connected to the public internet, while the model was informed it was in a simulated environment without internet access.Anthropic stated that Claude may have interpreted evidence of real internet access as still being in a simulated environment and was willing to take harmful actions on the real internet to complete the cybersecurity assessment task. Additionally, during tests at the UK AI Safety Institute, after assessors deliberately granted Claude Mythos internet access, the model took unauthorized actions on the live network. Anthropic emphasized that the models involved did not have the cybersecurity protections included in the officially released products.Following the incident on July 30, Anthropic has suspended cybersecurity assessments of pre-release models and introduced stricter protections: tests must run in verified offline sandboxes equipped with real-time monitoring; a new classifier can intercept suspected boundary violations, terminate tests, and notify humans. Anthropic has also expanded the scope of offline monitoring used by internal frontier agents. Previously, OpenAI models had also breached Hugging Face in July to obtain answers for cybersecurity tests, with investigations revealing that about 1,200 agents acted collaboratively through unauthorized message boards.

U.S. Treasury Secretary Benczkowski vowed at the beginning of this week to launch an "economic assault" against Iran and its trading partners, once again attempting to end the war. However, by the weekend, countries with ties to Iran have so far dismissed this threat, and analysts are disappointed with the actions taken by the U.S.As the week nears its end, the U.S. announced plans to sanction the branch of Egypt's Misr Bank located in the UAE. Previously, Benczkowski had warned that the world would see "significant news of a financial institution being sanctioned before the end of this week," making this move far below expectations.Alex Zerden, a former U.S. Treasury official and founder of Capitol Peak Strategies, stated, "The actions publicly taken by the U.S. Treasury this week do not match the prior hype. The 'economic exile action' continues the restrictive economic measures against Iran that have been in place for 47 years, but it does not provide a clearer path for how this current action will achieve economic or military victory."

Cosmos Labs released a technical report, admitting that it previously misjudged an integer underflow vulnerability in the Cosmos EVM, which led to attacks on six blockchain networks between August 20 and 25, resulting in a total theft of approximately $5.7 million in tokens. The attacker exploited the vulnerability to underflow account balances to the maximum value of 2^256-1, then performed a reverse operation to transfer the inflated balance out, thereby stealing tokens from the target accounts without creating tokens out of thin air.The report shows that researchers submitted the defect through a bug bounty program on April 25, but testers were unable to reproduce it on the existing Cosmos chain configuration, so Cosmos Labs silently patched it in May. Independent researchers confirmed in early August that the vulnerability affected all Cosmos EVM chains, and Cosmos Labs released a patch on August 19, but the first attack occurred about 20 hours later.In terms of specific losses, MANTRA lost 720.9 million tokens (approximately $3.6 million), TAC lost nearly 3 billion TAC, and KiiChain lost about 148 million KII. Both MANTRA and KiiChain criticized Cosmos Labs for not notifying the affected chains in advance and suggesting a shutdown, with KiiChain stating that the patch would take several days to deploy while a shutdown would only take a few minutes. Cosmos Labs stated that it has coordinated responses with 40 chains and assisted 13 chains in completing repairs or shutdowns before being attacked.

Polish Olympic Committee President Radosław Piszczek was arrested on Thursday, suspected of receiving kickbacks from the cryptocurrency platform Zondacrypto during the signing of a sponsorship agreement. Polish Sports Minister Jakub Rudnicki confirmed the arrest on the X platform, stating, "Such a person should not hold the position of President of the Polish Olympic Committee; Piszczek has brought shame to Polish sports." Interior Minister Marcin Kwiatkowski referred to him as "a symbol of extreme corruption plaguing the Olympic movement."According to the investigation, Piszczek facilitated the sponsorship agreement between the Polish Olympic Committee and Zondacrypto in October 2025, which promised cryptocurrency rewards to medalists of the 2026 Milan-Cortina Winter Olympics. The Polish government accused Zondacrypto of having ties to nationalist opposition groups, organized crime, and Russian intelligence agencies, estimating that the platform's collapse caused losses of about 350 million zlotys (approximately 80 million euros), affecting around 30,000 people. The Interior Minister described Zondacrypto as "essentially a Ponzi scheme."Media investigations also revealed that Piszczek received a Patek Philippe watch worth approximately 40,000 euros from Zondacrypto CEO Przemysław Kral, who claimed the watch was purchased out of his own pocket. Kral is currently cooperating with prosecutors in hopes of a reduced sentence. Zondacrypto was founded by Sylwester Sucheck in 2014, who went missing in 2022, with Kral taking over his position. The Polish prosecutors launched an investigation in April of this year, and most Polish sports federations subsequently called for Piszczek's resignation.
