Odaily Report: Vitalik posted on X platform, stating that for those who support vaccines, or who criticize vaccines but are open to the following view—that vaccines could play a significant role if developed in a more open-source, open-science manner that serves the public—he strongly recommends learning about PopVax.

Odaily reports: Zcash full-node development team Zakura has stated that the network is expected to introduce a quantum-resistant signature opcode in January, enabling hash-based signatures for transparent payments. Zcash's transparent payments publicly display transaction information, while shielded payments hide the sender, receiver, and amount.The proposal combines address rotation with private information retrieval, allowing wallets to switch to a new address after each transaction and reduce public key exposure risk through WOTS hash-based fallback signatures. The Vizor wallet launched its private query feature this week, allowing users to enable it for testing in the settings.Zakura's proposal currently only covers Zcash transparent payments, and the network has not yet confirmed the activation time for the opcode. Ethereum researcher Justin Drake has warned that AI-driven mathematical breakthroughs could crack the relevant signatures in months rather than years; Vitalik Buterin believes it is possible that cryptographic technology could be broken within the next two years.

Odaily reports that Vitalik posted on X platform that for multisig, the ideal security rule is for each signer to change their key after every operation. The implicit assumption of this rule is that ECDSA may become insecure, but will not be instantly broken, so it is still necessary to guard against mempool front-running. Vitalik stated that if possible, signatures should still be collected offline to minimize the time gap between "signature exposure" and "key invalidation"; misconfigured and rushed upgrades can easily lead to loss of funds, so do not act hastily.

Odaily News: Ethereum co-founder Vitalik Buterin posted on X that AI-accelerated mathematics research could pose new security threats to existing cryptographic systems, especially lattice-based cryptographic schemes, including ML-DSA and fully homomorphic encryption (FHE). He believes that AI progress in mathematics over the next two years could significantly weaken the practical security of lattice cryptography, and ECDSA may also face the risk of being broken sooner than expected.Vitalik pointed out that over the past year, Ethereum's Lean roadmap has been gradually shifting toward pure hash-based cryptographic schemes, avoiding the use of lattice-based signatures and related zero-knowledge proof structures. He suggested prioritizing hash-based cryptography where feasible and adopting more conservative security parameters for lattice cryptography; privacy protocols should try to avoid storing encrypted information directly on-chain, and multisig wallets should prioritize off-chain signature confirmation.In addition, Vitalik suggested that users, when operationally convenient, store funds in addresses that have not yet initiated transactions to reduce potential risk, but he does not recommend that users immediately migrate assets on a large scale. He emphasized that migration operations themselves also carry risks, and his own losses caused by migration mistakes even exceeded the losses brought by previous hacker attacks.

Odaily reports: Vitalik Buterin shared Nethermind's development progress and stated that Nethermind is continuously improving Ethereum's efficiency and operating speed. Nethermind core developer Ben Adams said that its Beacon Chain plugin has completed syncing and is ready for the Glamsterdam fork on Sepolia; running Ethereum's execution layer and consensus layer as a single application appears to introduce no significant additional memory overhead. The Ethereum Foundation previously confirmed that Glamsterdam will activate on Sepolia on October 6, and Nethermind 2.1.0 already supports this upgrade.

Odaily reports that Vitalik Buterin stated that AI is demonstrating the ability to break out of sandboxes, attack websites, discover software vulnerabilities, as well as help discover vulnerabilities in the Ethereum protocol, implement complex cryptography, and conduct formal verification. About a month ago, he updated his ENS information for the first time without using a user interface, simply asking a local AI agent to write a script, and the operation was completed in about 5 minutes. He expects that AI directly executing complex onchain operations will gradually become the norm and become the new user interface in more scenarios. Vitalik Buterin also stated that the Safe-related hack caused approximately $1.4 billion in losses, with the attack targeting the interaction layer between users and onchain systems, rather than onchain contracts. AI directly handling transactions may reduce the risks brought by web interfaces, but it will also introduce new challenges such as AI security, prompt injection, and the accuracy of operational understanding.

Odaily reports that Vitalik posted on X platform that he is conducting a self-experiment, planning to use personal health and travel data to obtain personalized diet and exercise advice through frontier models, while avoiding leaking private information to remote models. A local Qwen 3.8 Flash Next model is used for coordination, with powerful remote models called as tools; the privacy scheme includes having the local model draft queries, isolating payment identity through zkAPI, and isolating network and IP information through Tor.Vitalik stated that the scheme is already running and returning suggestions, but Tor is not suitable for per-request unlinkability, with latency potentially 10 to 100 times higher than ideal; the request construction strategy is still suboptimal, and Qwen 3.8 Flash Next currently runs at approximately 20 to 30 TPS, and would only be noticeably faster above 100 TPS. He also stated that the more cautious the data provided to remote models, the less help remote models can offer.

Odaily News: After Vitalik Buterin released his open-source novel "Snowmoon," a same-name concept token $ZC (Zipcoin) appeared on-chain. GMGN data shows that $ZC's market cap briefly touched $20.89 million before falling back to approximately $14.34 million, with intraday gains at one point exceeding 41x; separate on-chain observations noted its market cap surpassed $15 million on the 29th.Some traders created separate tokens such as $SNOWMOON, $ZC, and $EMERALD based on elements from the novel including the book title, currency, and AI assistant, sparking a rapid round of speculation around the text's worldbuilding.After $ZC launched on STOCKER, it drove $STOCKER up approximately 10x at one point, with related observations noting its market cap at around $15 million, while $STOCKER was approximately $7 million.Around the "Snowmoon" narrative, some have further speculated that Vitalik was "disguising" a privacy coin whitepaper within the novel
