ChainCatcher message, Slow Mist Yu Xian forwarded a security case about hardware wallet usage on platform X: "A user stored BTC in a hardware wallet thinking it was safe, but after a few years, when they took it out, they found the battery had swollen and it was unusable. They found the same model wallet and went to Huaqiangbei to replace the battery, only to discover that the wallet had been initialized and there was no backup, resulting in a permanent loss. This serves as a reminder that if you use a hardware wallet, you must also ensure proper backups. If you need to repair a hardware wallet, make sure to find a professional hardware team."Yu Xian commented on this: "After a few years, the battery has swollen and the wallet has been initialized? Which hardware wallet is this? We need to avoid it... If there is a mnemonic backup, it can be tolerated... But without a backup, it's really..."

ChainCatcher message, Slow Mist's Yu Xian disclosed that the phishing technique of poisoning addresses with similar starting and ending numbers is still widespread, severely impacting the security infrastructure of the blockchain industry.Yu Xian pointed out that this type of poisoning targeting wallet transaction history mainly involves various techniques, including fake token contract codes emitting false event logs to deceive block explorers and wallets, as well as using zero-amount transfer event logs to arbitrarily fill in addresses in the from/to fields. These techniques can mislead users into believing that the transactions are from their own actions. Other common techniques include sending small amounts of funds from source addresses with the same starting and ending characters, combining clipboard hijacking technology, and impersonating well-known decentralized exchanges to output false event logs.Yu Xian recommends that users make good use of wallet whitelisting mechanisms, carefully verify complete addresses, and combine well-known hardware wallets for dual verification as defensive measures.Previously reported, two addresses suffered "transaction history pollution attacks" in the past 14 hours, resulting in a total loss of over $140,000.

ChainCatcher message, Slow Mist's Yu Xian posted on platform X stating that if you are still using Safe multi-signature or other multi-signatures (regardless of the technical model), you need to pay attention to the following points:All signature steps must be verifiable. If a technically knowledgeable friend struggles for a long time and cannot verify, you should default to suspicion.Since you are using multi-signature, if it can be paired with a hardware wallet, especially one that can effectively handle complex signature parsing and alert you to signature anomalies, it is best to use them together.The security mindset is to never trust a single party; there is always a risk of a single point of failure, so it is best to have multiple verifications.

ChainCatcher news, the Web3 industry research and analysis platform Web3Caff Research recently released an in-depth report on the ZKP hardware acceleration project Cysic. Web3Caff Research researcher Bob pointed out in the report that zero-knowledge proofs (ZKP) have a history of nearly 40 years and are widely used in privacy protection and layer two scaling in blockchain. However, due to high computational resource consumption and slow verification speeds, user growth is limited. Therefore, hardware acceleration has become a key solution. FPGA and GPU have already implemented multiple ZKP products, while the more performant ASIC is considered the "Mount Everest" of the industry due to high costs and uncertainties. Currently, Cysic, as the only team developing ZKP ASIC, has the potential to unlock a market worth billions.The report further points out that ZKP is one of the core technologies of Web3, and ZKP hardware acceleration is still in its infancy. Compared to Cysic, both the current industry methods of operating open-source code libraries to accelerate GPUs and building FPGA clusters are still in the early trial-and-error stage. Cysic provides a user-friendly ZKP acceleration solution and is currently the only product open for testing and pushing to the market, with its testnet having entered Phase 2. Its performance is claimed to be 5 to 10 times faster than GPU acceleration, with plans to launch the mainnet by the end of 2024. Additionally, Cysic's ZK-ASIC hardware products are highly anticipated, with two models expected to be launched in 2025, targeting both enterprise (B-end) and consumer (C-end) markets. Although there are doubts about ZK-ASIC within the industry, from a long-term development perspective, introducing ASIC to establish a ZKP "mining" model could be a key step in promoting ecological development.

ChainCatcher news, according to The Block, Evan Cheng, co-founder and CEO of Sui blockchain development company Mysten Labs, stated in an interview in May that the "ChatGPT moment" for cryptocurrency could arrive at any time. In a recent interview at the Mainnet conference, Cheng reiterated that the moment has not yet arrived, but it is still just around the corner. As for how Cheng plans to lead Sui to this breakthrough, he believes that by catering to "disruptive developers" and conducting extensive experiments, his blockchain has the most potential to achieve this breakthrough.One of the upcoming eye-catching experiments from Sui is the SuiPlay0X1 handheld gaming device, which is now available for pre-order and is scheduled to launch in 2025. While some may view the device as a hardware play, similar to Solana's Web3 phone, Cheng sees the device as a software product rather than a hardware product.Cheng said, "This is a gaming device that can play all Windows games. It is better than other devices in terms of deep software integration and operating system integration. Even for existing Web3 gamers, it is a superior product due to the advantages of the software. Hardware is almost like a commodity, while the software experience is where the magic lies and is the key to success."Market data shows that SUI briefly reached $2.2485, setting a new all-time high.

ChainCatcher news, according to Decrypt, the lawsuit against the cryptocurrency company Green United by the U.S. Securities and Exchange Commission (SEC) has recently drawn industry attention. The SEC accuses Green United of defrauding investors of $18 million through the sale of so-called "Green Boxes" mining equipment. Last week, a federal judge dismissed Green United's motion to dismiss, sparking speculation on social media that the sale of cryptocurrency mining hardware could be considered securities. However, several legal experts stated that there is currently no reason for excessive concern.Ishmael Green, a partner at Diaz Reus law firm, pointed out that as long as the mining equipment is sold with the understanding that it will be used for mining by the end user, there should be no issue. "In the Green United case, the sales agreement for the mining equipment states that Green United will control and operate the system, which is the problem." Hadas Jacobi, a consultant at Reed Smith law firm, stated that although the SEC did not explicitly mention hosted mining, it could have implications for hosted mining services. While Green United attempted to portray the case as the SEC misunderstanding hosted mining, the judge denied its motion to dismiss. Currently, the judge has only decided to hear the case and has not ruled on the SEC's arguments.
