According to Onchain Lens monitoring, Vitalik Buterin (0xfEB...03B2) transferred 1 million USDC to his charitable project Kanro Fund, equivalent to approximately 1 million dollars.

Vitalik Buterin stated that he supports Kimi 3.1's active exclusion of top offensive cybersecurity capabilities in training data, believing that "limiting use cases" is far better than "limiting users." He pointed out that society still needs time to prepare for more powerful AI cyberattack capabilities, including strengthening system security, reviewing old code, and conducting rigorous formal verification of new code.Vitalik warned that if the first wave of significant AI risks is mishandled, the future may lead to a situation of highly closed models, comprehensive KYC thresholds, and mass surveillance, where different users may receive different levels of model access based on identity, qualifications, or nationality.

Vitalik Buterin posted on the X platform stating that he does not predict that defense will automatically lead over offense, but believes that cybersecurity will ultimately trend towards a favorable outcome for defense, although the transition process will be very difficult.He pointed out that "good people discovering vulnerabilities in released software before bad people" does not belong to a game where defense has the advantage. To truly tilt the game towards defense, a deeper methodological shift is needed, including formal verification, radical reduction of the Trusted Computing Base (TCB), etc., and currently, these shifts have only just begun. He also stated that this is an important reason for his friendly attitude towards slowing down or pausing AI development, and called for investing more than 1% of GDP into cybersecurity, biosecurity, and the fortification of the physical world.

Vitalik Buterin (@VitalikButerin) posted that the ideal path for supporting various cryptographic algorithms is through EIP-8288: users generate arbitrary signatures locally, then prove them through STARK, and aggregate them on-chain via STARK, without occupying calldata on-chain, thus Ethereum does not need to add new precompiles. He also mentioned that if lattice cryptography is proven to have security against AI attacks, it can still be used in scenarios such as accounts and wallets through precompiles in the future.Previously, Starknet co-founder Eli Ben-Sasson expressed disagreement with a16z's related views, stating that lattice cryptography has a rich mathematical structure that is vulnerable to AI attacks, and that a simplified version based on modular SIS only appeared in 2012 and lacks maturity. He suggested waiting another 3-5 years until AI has been thoroughly tested before using it for custody of large assets.

Ethereum co-founder Vitalik Buterin shared that the cost of Bitcoin mining is roughly half derived from capital expenditures on computing power equipment and the other half from electricity consumption; in contrast, the cost of AI inference is almost entirely dominated by capital expenditures on computing power. This difference reflects the distinct cost structures of the two computing businesses. Bitcoin miners need to continuously pay for electricity and determine their profit margins based on mining machine efficiency, coin prices, and network difficulty changes; AI inference, on the other hand, relies more on investments in expensive hardware like GPUs, as well as equipment utilization and computing efficiency.The industrial boundaries of both are also changing. As the demand for AI computing power grows, some Bitcoin mining companies are beginning to shift their existing electricity resources and data center facilities towards AI and high-performance computing businesses, hoping to transition from pure mining to computing infrastructure services. Some mining companies are leveraging previously allocated electricity capacity for mining to enter the AI data center market. However, transformation does not mean that cost pressures disappear: mining operations are more directly exposed to fluctuations in electricity prices and Bitcoin prices, while AI computing businesses must bear risks related to GPU procurement, depreciation, and underutilization. Both types of businesses compete for electricity and computing resources, but ultimately, profitability depends on how these resources are converted into revenue.

Ethereum co-founder Vitalik Buterin posted on the X platform that he has integrated zkAPI, Tor, additional obfuscation traffic, and local LLM prompt rewriting into a daemon compatible with the OpenAI interface, and created a "paranoid mode" wrapper for his AI agent tool pi. The relevant code has been open-sourced on GitHub.The main mechanism of this solution is as follows: each conversation uses a separate Tor line, with requests mixed in random obfuscation traffic; zkAPI is used to prevent identity leakage through payment links; all prompts are first rewritten by a local model, which the user can choose, with Vitalik himself using qwen3.8-flash-next. The outer layer of the proxy tool is wrapped in a bwrap sandbox, and then another layer of torsocks is added, ensuring that all network operations go through Tor.Vitalik stated that this solution is already quite usable, but the latency has significantly increased, especially slow when starting a new conversation. He pointed out that Tor is far from the best privacy solution in this scenario: obfuscation traffic can prevent passive eavesdropping, but if the LLM service provider colludes with the Tor entry node and actively manipulates timing, the protective effect will be greatly weakened.

According to on-chain intelligence platform Arkham, the total value of on-chain assets held by Ethereum co-founder Vitalik Buterin is approximately 530 million USD, of which 527.81 million USD is in ETH, distributed across multiple addresses (including vitalik.eth).The remaining assets include 1.76 million USD in Aave LUSD, 478,000 USD in ZCHF, and 346,000 USD in WHITE.

Vitalik posted on the X platform to congratulate the @zksync Airbender team for achieving this milestone. He believes that the speed competition of zkEVMs has achieved a decisive victory, and the primary focus should shift entirely to security.Vitalik stated that this means there is a need to formally verify the equivalence of arithmetic and Ethereum specifications, the hard upper limit of the ratio of prover costs to total block Gas, and the security of the proof system itself.

On October 9, Binance founder CZ posted on X, responding to Ethereum co-founder Vitalik Buterin's lengthy article about the potential impact of artificial intelligence accelerating mathematical research on cryptographic security. CZ rated Vitalik's mathematical level at 99.99 points, while he rated himself at 0.01 points, joking that together they might achieve something; he also mentioned that people might not fully understand Vitalik's articles like himself, but even so, such analytical discussions are worth reading.Previously, Vitalik warned in a post that the acceleration of mathematical research by artificial intelligence could significantly weaken the practical security of lattice-based cryptography in the next two years, involving technologies such as ML-DSA and fully homomorphic encryption, and could even expose ECDSA to cracking risks sooner than expected. He believes that artificial intelligence could drive mathematical research progress equivalent to the past 50 years within two years, which is why the Ethereum Lean roadmap has gradually shifted towards pure hash signature schemes over the past year, reducing reliance on lattice cryptography.

Ethereum co-founder Vitalik Buterin posted on the X platform, stating that AI-accelerated mathematical research may pose new security threats to existing cryptographic systems, especially lattice-based cryptographic schemes, including ML-DSA and fully homomorphic encryption (FHE). He believes that advancements in AI in the field of mathematics over the next two years could significantly undermine the practical security of lattice cryptography, and ECDSA may face the risk of being compromised sooner than expected.Vitalik pointed out that over the past year, the Ethereum Lean roadmap has gradually shifted towards pure hash cryptographic schemes, avoiding the use of lattice-based signatures and related zero-knowledge proof structures. He suggested prioritizing the use of hash cryptography whenever feasible and adopting more conservative security parameters for lattice cryptography; privacy protocols should avoid storing encrypted information directly on-chain, and multi-signature wallets should prioritize off-chain signature confirmations. Additionally, Vitalik advised users, when operationally convenient, to store funds in addresses that have not initiated transactions to reduce potential risks, but he does not recommend users immediately migrate assets on a large scale. He emphasized that the migration process itself also carries risks, and his own losses due to migration errors have even exceeded the losses from past hacking attacks.

Vitalik Buterin retweeted Nethermind's development progress and stated that Nethermind is continuously improving the efficiency and operating speed of Ethereum.Nethermind core developer Ben Adams mentioned that its Beacon Chain plugin has completed synchronization and is ready to handle the Glamsterdam fork on Sepolia; running the Ethereum execution layer and consensus layer as a single application does not seem to incur significant additional memory overhead.The Ethereum Foundation previously confirmed that Glamsterdam will be activated on Sepolia on October 6, and Nethermind 2.1.0 has supported this upgrade.

ChainCatcher live report, at the OKX NOW Global Product and Ecosystem Conference (Singapore), Ethereum co-founder Vitalik Buterin stated that AI has demonstrated strong penetration and offensive and defensive capabilities, with cases emerging of breaking out of sandboxes, attacking websites, and discovering various software vulnerabilities and exploits. "Anything with vulnerabilities will eventually be discovered by AI; GPT-7, Claude 7, DeepSeek 7 will find it."At the same time, AI is also helping the Ethereum protocol discover bugs, implement complex cryptography, and perform formal verification at both the protocol and application layers. Vitalik believes that higher security levels will shift from "optional" to "mandatory," and the industry is in a fascinating yet challenging transitional period.

ChainCatcher live report from the OKX NOW Global Product and Ecosystem Conference (Singapore), where Ethereum co-founder Vitalik Buterin delivered a keynote speech. He stated that AI is both the biggest opportunity and the biggest risk for the current industry development.He believes that the industry is moving beyond the narrative of "blockchain + programmable value," with new features such as "programmable data" realized through zero-knowledge proofs (ZKP) emerging.Vitalik expects that privacy protocols on Ethereum will rapidly mature, and within the next two years, most people are likely to use these technologies in an "unperceived" manner.

At the OKX Now 2026 Summit in Singapore, Ethereum co-founder Vitalik Buterin stated that AI is demonstrating the ability to break out of sandboxes, attack websites, and discover software vulnerabilities, while also helping the Ethereum protocol identify vulnerabilities, implement complex cryptography, and conduct formal verification.He believes that higher levels of security will become feasible and necessary, as AI will continuously discover exploitable vulnerabilities within systems.Vitalik revealed that about a month ago, he updated ENS information for the first time without using a user interface (UI), only requiring a local AI agent to write a script, which was completed in about 5 minutes. He anticipates that executing complex on-chain operations directly through AI will gradually become the norm, with AI becoming a new user interface in more scenarios.He cited the Safe-related hacking incident involving approximately $1.4 billion in losses as an example, pointing out that the attacks targeted the interaction layer between users and on-chain systems, rather than the on-chain contracts. Directly handling transactions with AI may reduce the risks associated with reliance on web interfaces, but it will also introduce new challenges, including whether the AI itself is secure, whether it can resist prompt injection, and whether it correctly understands on-chain operations. As interaction methods change rapidly, some issues will be resolved, while new security challenges will also emerge.

Vitalik.eth posted on Farcaster revealing that he is conducting a personal experiment to generate personalized diet and exercise recommendations using personal health and travel data by combining local models with remote cutting-edge models while protecting privacy.The system employs a three-layer privacy protection architecture:Identity Layer: A local model (Qwen 3.8B) replaces the user to construct query requests, avoiding the exposure of writing style that could reveal identity.Payment Layer: Uses zkAPI to hide payment information.Network Layer: Hides IP addresses through Tor.The system is currently operational, but Vitalik pointed out three major shortcomings: Tor is inefficient and has high latency in unlinking requests; the local model runs at only 20-30 TPS, and a smooth experience requires over 100 TPS; the stricter the data protection, the more limited the assistance that the remote model can provide. The relevant code has been submitted to the Ethereum zkAPI repository.

According to The Block, the Ethereum Foundation has launched zkAPI on the Ethereum mainnet, a solution co-authored by Vitalik Buterin.zkAPI allows users to pay for artificial intelligence and other APIs using pre-stored ETH or USDC through zero-knowledge proofs, making it impossible for service providers to associate specific requests with the payer.

Ethereum co-founder Vitalik Buterin released the plan for "The Computer of the Crypto World," stating that the Hegota fork scheduled for next year may be Ethereum's last "regular" fork, with subsequent upgrades introducing recursive STARK, automated formal verification, optimized consensus, and quantum security capabilities.He indicated that Ethereum will transition from a blockchain to a hybrid architecture that integrates modern cryptography. This roadmap aims to shorten transaction finality to 8 to 32 seconds, significantly reduced from the current approximately 200 seconds with 12 confirmations, and will adjust verification, consensus, and block construction mechanisms through PeerDAS, SNARK, and FOCIL.

According to CoinDesk, Ethereum co-founder Vitalik Buterin has released a long-term roadmap, referred to as Streamlining Ethereum. The vision proposes that by 2030, Ethereum will surpass a mere blockchain ledger and plans to completely restructure the protocol in the next three to four years.The transformation includes expanding transaction throughput by approximately 1000 times, introducing zero-knowledge proofs to enhance privacy and combat quantum computing threats. By 2030, the network is expected to accommodate 2TB of traditional dynamic state data, along with an additional 100TB of new scalable storage, to achieve underlying state separation and optimization. The vision also aims to establish Ethereum as an infrastructure driven by cryptographic validation, with applications extending from finance to social systems. Most developers support this plan, although some voices believe the implementation timeline is somewhat delayed.
