Vitalik: Blockchain has evolved from a simple ledger into a cryptography-based secure computing network

Vitalik Buterin, co-founder of Ethereum, delivered a keynote speech at the 12th Global Blockchain Summit, stating that the blockchain was initially a primary tool. Although it has characteristics such as openness, neutrality, and security, it is not scalable and is completely transparent, lacking privacy protection mechanisms.Subsequently, privacy transactions and scalable verification brought by zero-knowledge proofs have changed this situation and have been transformed from planning into actual EIPs, included in the Ethereum roadmap. Technologies such as fully homomorphic encryption are also beginning to be applied, and indistinguishable obfuscation may also be applied on-chain in the future. Beyond privacy, the parallel construction and proof of blocks can make extreme scalability possible, and industry thinking has shifted from digital assets to digital assets plus information, from purely on-chain to user-end, transaction memory pools, a complete pipeline on-chain, and from who can send what to who can see what.Currently, blockchain has gradually evolved from a simple ledger to a cryptography-based secure computing network. With the development of AI, providing cryptographic rules to AI for automated formal verification can significantly enhance verification efficiency, allowing the chain to carry more possibilities.

U.S. Republican Senator John Curtis called for an investigation into Donald Trump Jr. and Hunter Biden, involving cryptocurrency business

U.S. Senator John Curtis from Utah, a Republican, wrote to Chuck Grassley, the Chairman of the U.S. Senate Judiciary Committee, and Dick Durbin, the Chief Minority Whip, calling for an investigation into whether Donald Trump Jr. and Hunter Biden exploited their presidential family connections for personal financial gain, and requested subpoenas for both individuals. Curtis pointed out that Donald Trump Jr. had accepted wedding gifts from Russian oligarch Umar Kremlev, actively promoted family-backed cryptocurrency ventures, and served as an advisor for a prediction market platform; the related companies are regulated by the Commodity Futures Trading Commission. Donald Trump stated that his son has returned the relevant funds to Umar Kremlev.Curtis also called for an investigation into Hunter Biden's substantial business dealings with foreign entities, as well as whether the two utilized their relationship with the president to create commercial value. He mentioned that Joe Biden pardoned Hunter Biden in December 2024, who had previously denied involving his father in business transactions. A week prior to this investigation call, Senate Republicans failed to garner enough Democratic support to advance the Digital Asset Market Clear Act. Some Democratic senators opposed the bill, citing reasons including Donald Trump's use of cryptocurrency ventures to gain benefits related to the presidency; Donald Trump disclosed that he earned $1.4 billion from digital asset-related businesses in 2025.

first_img Fake AI trading robot tutorial deceives 224 victims into deploying malicious contracts

On September 14, blockchain intelligence company TRM Labs released a report revealing that fake YouTube tutorials lured 224 victims into deploying and funding malicious smart contracts under the guise of building AI-based crypto arbitrage bots, resulting in the theft of 274.6 ETH. TRM identified a total of 234 contracts deployed by the victims, with funds ultimately flowing into six collection addresses controlled by the operators. The stolen ETH was worth approximately $517,000 at the time of the transfer, with a median loss of 1 ETH per incident.Unlike common wallet theft attacks, this scam did not involve phishing links, spoofed domains, or malicious authorization prompts. Victims chose the tutorials themselves, copied the code, deployed the contracts, and funded them from their own wallets, with each step authorized by the victims themselves. As a result, wallet security warnings and phishing blacklists could not be triggered. TRM discovered nine nearly identical YouTube tutorials disguised as different creators, using AI-generated virtual hosts and voiceovers, promising to build fully automated crypto trading bots with Claude, and guiding victims to a compiler website controlled by the operators, some of which mimicked the commonly used Remix development environment.In one variant analyzed by TRM, a backend script would discard the source code pasted by the victims and retrieve another contract from the operator's server, with the clean code displayed on the screen never being on-chain. The replaced contract accepted deposits and transferred any balance over 0.05 ETH to the operators when the victims pressed Start or Withdraw, with no arbitrage logic or AI functionality included in the contract.
