BlockBeats News, April 22nd, according to Decrypt, the an exchange Quantum Computing and Blockchain Independent Advisory Board released a report on Tuesday stating that Proof of Stake (PoS) blockchains may face a greater future risk of quantum computing attacks, as the cryptography relied upon for the validators' signatures that protect these networks could ultimately be broken by sufficiently powerful quantum computers. The report pointed out that PoS networks such as Ethereum and Solana rely on cryptographic signatures—Ethereum validators use BLS signatures, Solana validators and users use Ed25519 signatures—to help the network agree on blocks and maintain consensus. The advisory board stated: "There is an exposure risk in the signature schemes validators use to protect the PoS chain, meaning that the challenge facing PoS is not just upgrading wallets, but parts of the core consensus mechanism itself may need to be redesigned." The report mentioned recent work by Ethereum developers, including co-founder Vitalik Buterin's proposal in February to replace BLS validator signatures with a quantum-resistant alternative, KZG commitments, and ECDSA wallet signatures. The committee also identified digital signatures used by encrypted wallets as another major long-term vulnerability, estimating that about 6.9 million bitcoins fall into the category of public keys visible on the chain. The report stated that the current cryptocurrency system remains secure as quantum computers capable of breaking modern cryptographic signatures do not yet exist.

Chip distribution data shows: In the past six months, 50% of ETH trading volume was concentrated in the $1,836.70-$2,491.11 range, with the price of most concentrated trading (POC) at $2,063.23. Currently, the ETH price is operating in the middle of this range and above the POC, indicating that the short-term bulls have a slight advantage, though the advantage is not significant. The POC line is a key psychological support below. For more chip distribution data on different periods or cryptocurrencies, please activate the PRO version of the K-line chart.

Jinse Finance reported that on April 22, JPMorgan stated in a research report that if the U.S. Navy successfully carries out a maritime physical blockade, it will force Iran to cut its oil production. Analysts including Natasha Kaneva wrote in a report issued on April 21: Such blockade measures would not only impose restrictions from a financial perspective but would also directly constrain the total volume of crude oil exports, drastically reducing Iran’s space to conduct trade through circumvention channels and forcing Iran to reduce production over the long term. Iran’s onshore crude oil storage capacity is about 86 million barrels, with a current utilization rate of 54%, leaving approximately 40 million barrels of available storage—the equivalent of around 22 days’ worth of oil exports. In addition, around four supertankers linked to Iranian operations are anchored in the Strait of Hormuz, with a total capacity of about 8 million barrels of crude oil, which could extend the export deadline to roughly 26 days. If export routes are completely cut off, Iran will be forced to start reducing production in around 16 days; by about day 30, the scale of production cuts will continue to increase until crude oil exports are almost entirely halted, with daily production cuts reaching approximately 1.9 million barrels. The analysts added that while this blockade might strengthen the U.S. position in negotiations, this depends on rigorous and sustained enforcement of such measures, which are expected to last several months.
