BlockBeats News, April 22, According to a report by Decrypt, the Coinbase Quantum Computing and Blockchain Independent Advisory Committee stated on Tuesday that Proof-of-Stake (PoS) blockchains may face greater exposure risks to future quantum computing attacks, as the cryptography relied upon by validator signatures that secure these networks could eventually be broken by sufficiently powerful quantum computers. The report notes that PoS networks like Ethereum and Solana depend on cryptographic signatures—Ethereum validators use BLS signatures, while Solana validators and users employ Ed25519 signatures—to help the network reach consensus on blocks and maintain agreement.The advisory committee stated: "PoS chains have exposure risks in the signature schemes used by validators to secure the network, meaning the challenges for PoS go beyond merely upgrading wallets; parts of the core consensus mechanism itself may need to be redesigned." The report mentions recent work by Ethereum developers, including a proposal by co-founder Vitalik Buterin in February to replace BLS validator signatures, KZG commitments, and ECDSA wallet signatures with quantum-resistant alternatives. The committee also listed digital signatures used by crypto wallets as another major long-term vulnerability, estimating that about 6.9 million bitcoins fall into the category where public keys are already visible on-chain. The report asserts that current cryptocurrency systems remain secure because quantum computers capable of breaking modern cryptographic signatures do not yet exist.

PANews reported on April 22nd that, according to The Block, Ethereum ecosystem marketing firm Etherealize updated its long-term ETH price forecast to $250,000, a downward revision from its previous target of $740,000. Etherealize co-founder Vivek Raman stated that if Ethereum captures the same value storage premium as Bitcoin and gold (which together account for approximately $31 trillion), based on the current circulating supply of 121 million ETH, the implied price of ETH would exceed $250,000. The report argues that ETH is unique in monetary history, serving as both a store of value and a productive asset generating returns through a proof-of-stake consensus mechanism, breaking the historical trade-off between "safe money" and "productive investment." The report also points out that Ethereum is already the dominant settlement layer for tokenized assets, stablecoins, and decentralized finance, with the network limiting supply growth to 1.5% annually by burning a portion of transaction fees, and potentially even experiencing deflation as usage increases.

BlockBeats news, April 21st, last night and this morning, Trump repeatedly stated that the ceasefire agreement is set to expire on Wednesday evening Washington time, and it is "extremely unlikely" that the ceasefire agreement will be extended.At the same time, Trump said that Vance will travel to Pakistan later on Monday, and "the Strait of Hormuz will not be opened until the agreement is signed." On the other hand, Iran insisted on "not backing down" during U.S. stock market hours, stating that "the decision not to participate in negotiations has not changed." However, U.S. media reported that "the Iranian delegation will arrive on Tuesday morning, close to the arrival time of the U.S. delegation."Affected by Iran's tough stance, according to Bitget market data, the S&P 500 closed down 0.24% on Monday, the Nasdaq fell 0.26%, and the Dow Jones Industrial Average remained essentially flat. Crude oil varieties saw slight gains, with Brent crude rising 2.51%, currently at $90.39.Bitcoin showed relative strength, possibly boosted by Strategy's significant increase in holdings. According to HTX market data, Bitcoin broke through $76,000 again this morning, currently at $75,853.42, with a 24-hour increase of 0.19%.Investors are currently highly focused on whether the U.S.-Iran situation will escalate again. Over the next day or two, whether the Iranian delegation can appear in Islamabad in time and whether peace talks can resume are the main market concerns.

Deep Tide TechFlow News, April 20th: According to an official announcement from Curve Finance, due to a hack on the rsETH LayerZero infrastructure, Curve Finance has announced a suspension of its LayerZero infrastructure for security reasons, with resumption pending further investigation into the root cause. This suspension affects: CRV cross-chain bridging functionality from chains such as BNB Chain, Sonic, Avalanche, Fantom, Etherlink, and Kava (chains using native bridging are unaffected), as well as crvUSD fast bridging functionality (L2 slow bridging remains operational). Meanwhile, it is reported that KelpDAO also suffered a vulnerability attack, involving approximately $291 million, with specific losses still under investigation.

PANews reported on April 20th that, according to The Block, eth.limo, the ENS-to-Web gateway, suffered a DNS hijacking in the early hours of April 17th Beijing time. Domain registrar EasyDNS admitted to being the victim of a social engineering attack, marking the company's first successful social engineering attack against a customer in 28 years. The attacker impersonated a member of the eth.limo team, tricking EasyDNS into performing an account recovery process, and subsequently changed the name servers twice. Because the attacker did not obtain eth.limo's signing key, DNSSEC verification rejected the attacker's changes, and the resolver returned an error rather than a malicious response. eth.limo stated that it is currently unaware of any affected users and will be migrating to the EasyDNS association service, which does not support account recovery. Vitalik Buterin had warned users during the incident to avoid using eth.limo links and access directly via IPFS, and confirmed on Saturday that the issue had been resolved.

PANews reported on April 20 that, according to Jinshi, Iranian officials have not yet responded to US President Trump's statement on April 19 that the US and Iran would resume talks in Islamabad. Iran's official news agency, IRNA, posted on its social media account that "Iran refuses a second round of negotiations with the United States." Iranian media believe that Trump's announcement, given the ongoing US naval blockade, is a form of "propaganda warfare" aimed at putting pressure on Iran. Analysts point out that Iran is preparing for all possible scenarios: According to Iran's Tasnim News Agency on April 19, Iran is prepared for a renewed conflict, promising its enemies an unforgettable "hellish experience" if fighting resumes; on the other hand, Iran is also prepared to participate in the negotiation process while adhering to its own demands. The two-week temporary ceasefire between the US, Israel, and Iran will expire on Wednesday morning, April 22 (Beijing time). Analysts emphasize that developments in the coming days are crucial, determining whether the parties return to the negotiating table and extend the ceasefire, or whether fighting resumes and conflict reignites.
