US Crypto Market Structure Legislation Delayed, Senate Banking Committee April Hearing Unlikely

On April 21, the Arbitrum Security Council announced it had taken emergency action to recover 30,766 ETH from an Arbitrum One address tied to the KelpDAO exploit. With law enforcement support, the Council identified the attacker’s identity—prioritizing the security and integrity of the Arbitrum community while ensuring no impact to users or applications. After extensive technical investigation and review, the Council deployed a solution to move the funds to a secure intermediate frozen wallet without altering any other chain state or affecting users. As of 11:26 PM Eastern Time on April 20, the transfer was completed successfully. The original funds-holding address can no longer access the assets; only Arbitrum custodians may take further action to transfer the funds, a process to be coordinated with all relevant parties.

April 21 — Ripple has officially unveiled its quantum resistance roadmap for the XRP Ledger (XRPL), targeting full quantum security for the network by 2028. The plan is primarily designed to counter the “Harvest Now, Decrypt Later” attack vector—where an adversary collects encrypted data today and decrypts it later using quantum computers. The roadmap unfolds in four phases: ### Phase 1: Q-Day Contingency Planning (In Progress) Establish a Quantum Day (Q-Day) contingency response framework. If existing classical encryption is suddenly compromised, the network will immediately stop accepting traditional public-key signatures, forcing a shift to quantum-secure accounts. Concurrently, explore asset ownership verification via post-quantum zero-knowledge (ZK) proofs—enabling existing holders to recover funds securely in emergencies without exposing vulnerable keys. ### Phase 2: Risk Assessment & Algorithm Testing (H1 2026) Conduct a full assessment of post-quantum cryptography’s imp

April 21 — Donald Trump posted on Truth Social claiming the “Midnight Thunderstrike Operation” has fully destroyed a nuclear dust facility in Iran, adding that cleanup efforts will be lengthy and arduous. He criticized fake news outlets like CNN and other corrupt media networks/platforms for failing to give the pilots the credit they deserve, and for constantly belittling and disparaging them.

**April 21: Quantum Computers Won’t Crack 128-Bit Symmetric Encryption Anytime Soon, Expert Argues** Cryptography engineer Filippo Valsorda said this week that real-world quantum computers won’t break 128-bit symmetric encryption (like AES-128) anytime soon—even with the fastest possible development pace. The current "post-quantum cryptography" panic, he noted, stems from a common misunderstanding. In his article *Quantum Computers Do Not Threaten 128-Bit Symmetric Keys*, Valsorda debunked the myth that the Grover algorithm would "halve" a symmetric key’s security (reducing 128 bits to 64 bits of protection). This claim ignores Grover’s critical practical flaw: it can’t be parallelized efficiently. Its steps must run serially, and forcing parallelization would skyrocket total computing costs. Even an ideal quantum computer would need ~2^104.5 operations to crack AES-128—tens of billions of times more expensive than breaking today’s asymmetric encryption (e.g., RSA, ECDSA)—making

April 21st — With U.S. midterm elections on the horizon, former President Donald Trump’s super PAC raised $35.6 million in March, pushing its campaign war chest to $550 million. That total sets a record for a midterm cycle as Trump aims to defend the Republican majority in Congress amid a tight battle. Federal Election Commission (FEC) filings show longtime GOP donor Diane Hendricks—who addressed the 2024 Republican National Convention—provided the bulk of the March fundraising, contributing $25 million. Venture capitalists Marc Andreessen and Ben Horowitz each gave $3 million. The California-based Yocha Dehe Wintun Nation tribal organization donated $2 million. A subsidiary of prison operator GEO Group Inc.—a federal contractor with clients including ICE—contributed $1 million. Amid this cash surge, polls indicate Trump’s 2024 voter coalition is fracturing. Historically, the party holding the White House typically loses House seats in midterms, and Democrats are growing more optimis
