Vitalik Buterin Argues Ethereum’s Biggest Use Case Is Data Availability

Vitalik Buterin argues that Ethereum's primary value is not smart contracts or payments, but its role as a censorship-resistant "public bulletin board" for data availability. This foundational layer is critical for cryptographic systems like secure voting and version control. Buterin highlights scaling solutions like PeerDAS, which significantly boost data capacity, positioning Ethereum as key infrastructure for a broader, privacy-preserving internet. While payments and smart contracts remain important, they are secondary, often serving anti-spam or security functions. He concludes that Ethereum is best understood as "global shared memory" and that current low fees and improved tooling make this vision more achievable than ever.

Bitcoin Defies Turmoil: Blasts Past $72K as Middle East Jitters Rattle Global Markets

Bitcoin (BTC) has surged past $72,000, demonstrating resilience amid heightened geopolitical tensions in the Middle East, rising oil prices, and a stronger U.S. dollar. Despite traditional risk assets experiencing volatility, BTC consolidated near its recent highs, with buyers actively supporting the $71,000 level. This behavior suggests Bitcoin may be weathering macro stress better than in the past, though some analysts caution that it remains vulnerable to broader deflationary pressures and could still face significant downside risks. Traders are advised to view the rally as occurring within a volatile environment rather than a definitive bullish turnaround.

Trump Memecoin Dangles Mar-A-Lago Access As Token Price Spikes 34%

The TRUMP memecoin, which had plummeted 96% from its January 2025 peak to an all-time low of $2.73, surged 34% to $3.82 after an announcement that top holders could gain access to a luncheon with former President Donald Trump at Mar-a-Lago on April 25. Eligibility is determined by time-weighted token balances held between March 12 and April 10, with the top 297 holders invited, subject to a background check. While the event's website lists Trump as the keynote speaker, the White House has not confirmed his attendance, noting a scheduling conflict with the White House Correspondents' Dinner. This marks the second such event, following a similar gathering at a Trump golf club last May, which drew protests and criticism over allegations that the president is monetizing access to his office. Prominent figures like Justin Sun and Kain Warwick attended the previous event.

Fed Set To Review ‘Toxic’ Bitcoin Basel Treatment For Major US Banks

The Federal Reserve is set to propose new rules next week implementing the final phase of Basel III for major US banks, sparking a debate over the current "toxic" regulatory treatment of Bitcoin. Under existing Basel guidelines, Bitcoin is assigned a punitive 1,250% risk weight, making it prohibitively expensive for regulated banks to hold or provide services related to Bitcoin. Critics, including Bitcoin Policy Institute's Conner Brown, argue this approach is a "category error" that mischaracterizes Bitcoin’s risk profile and stifles banking services for Bitcoin companies. The Fed’s proposal will enter a 90-day public comment period, offering an opportunity to challenge the harsh capital requirements and advocate for a risk-based framework instead.

US President To Host Exclusive Luncheon For TRUMP Holders April 25 At Mar-a-Lago

President Donald Trump will host an exclusive luncheon for TRUMP memecoin holders at Mar-a-Lago on April 25. A total of 297 holders will be selected to attend, with the top 29 qualifying for a VIP reception. Eligibility is based on time-weighted holdings as of April 10, 2026, and holders must maintain their token balance to retain VIP benefits. The event follows a similar gathering last year, though the token’s price has dropped sharply—from between $15–20 during the previous event to around $2.89 now, a decline of approximately 81% from its all-time high of $77. The announcement coincides with ongoing congressional discussions around the CLARITY Act, a crypto market structure bill expected to be reviewed in April, though its progress may be delayed.

Has Elon Musk Completely Abandoned Dogecoin? Here’s The Last Time He Tweeted About It

Elon Musk, a key figure behind Dogecoin's massive 36,000% rally in 2021, has significantly reduced his public engagement with the meme cryptocurrency. His last direct tweet about Dogecoin was over a year ago, in November 2024, where he defended its flat inflation mechanism as a feature rather than a flaw. Although Musk still subtly endorses Dogecoin by liking and reposting related content, his direct mentions have ceased. Furthermore, the recent launch of X Money (formerly Twitter) shows no integration of Dogecoin, despite earlier hopes. The payment feature, along with previous initiatives like Tip Jar, supports only Bitcoin and Ethereum, signaling a shift away from Dogecoin in Musk’s ventures.

FATF Releases Special Report on Stablecoins and Non-Custodial Wallets: Interpretation of Risk Threats and Response Strategies

FATF's report "Targeted Update on Stablecoins and P2P Payments" highlights the significant money laundering, terrorist financing, and proliferation financing risks associated with stablecoins, particularly through peer-to-peer (P2P) transactions involving non-custodial wallets. With stablecoins now accounting for 84% of illegal virtual asset transactions, the report emphasizes that unregulated P2P transactions are the primary vulnerability, as they bypass regulated intermediaries and complicate identity tracing. Key risks include cross-chain transactions, which obscure fund flows and weaken issuer controls, and data gaps due to missing off-chain information. FATF reiterates that its existing standards, especially Recommendation 15, must apply to all stablecoin ecosystem actors, including issuers and VASPs. Recommended measures include implementing whitelisting/blacklisting and asset freezing via smart contracts, enhancing blockchain analytics and AI tools, applying enhanced due diligence for non-custodial wallet transactions, and fostering public-private cooperation to address emerging threats.

Vitalik Wrote a Proposal Teaching You How to Stealthily Use AI Large Models

Vitalik Buterin and Ethereum Foundation's AI lead Davide Crapis co-authored a proposal titled "ZK API Usage Credits," which introduces a method for anonymously accessing AI models like ChatGPT using zero-knowledge proofs. Instead of requiring users to register and link personal information, the proposal suggests depositing funds (e.g., 100 USDC) into a smart contract. Users can then generate a zero-knowledge proof to verify they are on an encrypted whitelist and have sufficient balance—without revealing their identity. This approach aims to protect user privacy while preventing abuse. Although still in the research phase and facing skepticism, the proposal reflects Vitalik's broader focus on privacy and Ethereum's potential role in providing a tamper-proof data layer in the AI era, where verification and anonymity may become increasingly critical.

Your Backtest Is Lying: Why You Must Use Point-in-Time Data

The article warns that backtests using revised historical data are misleading due to look-ahead bias. It illustrates this with a hypothetical trading strategy based on Bitcoin exchange outflows from Binance: entering the market when the 5-day moving average of BTC balance falls below the 14-day average, and exiting on the reverse. Initial backtest results using current data appeared reasonably successful, even comparable to buy-and-hold at times. However, the author argues this is deceptive because metrics like exchange balances are often revised retroactively as new data arrives, meaning a backtest uses information that wasn't available in real-time. Re-running the identical strategy using Point-in-Time (PiT) data—which is immutable and reflects only what was known when the data was first published—yielded significantly worse performance. The PiT-based strategy failed to capture key market upswings as effectively, resulting in meaningfully lower cumulative returns. The key takeaway is that only immutable, Point-in-Time data ensures a backtest accurately replays history without look-ahead bias, and that using revised data will produce lying backtests.
