Today’s crypto headlines were driven by rising concerns about artificial intelligence and security, a performance milestone for Sui, and a sharp market reaction to geopolitical and oil-price developments. Researchers warned of potential cryptographic risks from AI advances even as one layer-1 project demonstrated extraordinary throughput, and exchanges registered large liquidations after risk assets sold off.
Warnings from Ethereum researchers about cryptography and AI
Ethereum Foundation researcher Justin Drake urged the industry to prepare for “bunker mode,” recommending a gradual transfer of funds to new addresses with unexposed public keys. Drake said ECDSA, the elliptic curve digital signature algorithm widely used in blockchain systems, could be compromised before an unspecified “Q-Day,” and in a worst-case scenario that could occur within "months, not years." He cautioned that a rushed transition could cause more harm than good. Vitalik Buterin expanded the concern to lattice-based cryptography, although the story notes there is currently no evidence that AI has actually cracked ECDSA.
These warnings follow the publication of hundreds of new mathematical results by OpenAI, according to the report, and reflect a wider unease about how advanced AI might affect cryptographic assumptions relied on across the industry. The article notes that brief background on ECDSA: it is a common digital signature scheme used to prove ownership of blockchain addresses.
Possible AI-assisted attacks on churches and banks in South Korea
Security incidents in South Korea were linked to AI activity in reporting for the day. Seoul’s Yoido Full Gospel Church said data for 850,000 members may have been compromised, and security firm Oasis Security found attack files on an external server that referenced AI "sub-agents." A second church, Sarang, reportedly lost records for about 89,000 members and 286 employees. Authorities are also investigating suspected AI-assisted attacks on banks, though the precise role of AI in these incidents remains unclear.
Sui records 40 million TPS in off-chain tunnel test
Sui reported that its off-chain "tunnels" reached 40,614,180 transactions per second during a live test in Singapore that simulated AI agent activity. The figure is substantially higher than the roughly 6.1 million TPS reported in July. The tunnel model executes transactions off-chain and settles on mainnet when the channel closes; the test opened over 10,000 tunnels simultaneously. CertiK is auditing the results and a report is expected. This is an off-chain scaling approach rather than an on-chain throughput measurement.
Cardano introduces regulated-token controls with CIP-0113
The Cardano Foundation launched the CIP-0113 standard, which allows issuers of regulated stablecoins, funds and bonds to implement controls that can restrict recipients and to freeze, seize or transfer holdings under specific rules. The specification applies only to tokens whose issuers adopt the standard and does not affect ADA, Cardano’s native token. CIP-0113 also advises lending services to consider the existence of these powers before accepting such tokens as collateral. The update does not require a hard fork to take effect.
Market reaction: oil shock and $547 million in liquidations
Markets turned volatile after Iran intensified attacks on tankers in the Strait of Hormuz and Brent crude rose above $101, which coincided with higher bond yields and a stronger dollar. Bitcoin slipped below $84,000 amid the move, and liquidations across crypto derivatives rose 235% to $547 million for the session, with $174 million of that tied to Ethereum positions. The CoinDesk 80 index fell nearly 4%, versus a 2.5% decline for the CoinDesk 5.
Day in brief
Today’s items underscore three overlapping themes: technical and security risks from advances in AI, ongoing product development and scaling experiments in layer-1 ecosystems, and the sensitivity of crypto markets to macro and geopolitical shocks. Regulators, projects and market participants are reacting in different ways, from technical standards like Cardano’s CIP-0113 to public calls for gradual cryptographic transitions, while third-party auditors and investigators follow up on high-profile tests and incidents.
