Xandeum, the decentralized storage network built on Solana, today began anchoring its state to Bitcoin. At every checkpoint of its consensus, Xandeum writes a cryptographic fingerprint of its storage state into the Bitcoin blockchain, where it cannot be altered or erased. Anyone, anywhere, at any point in the future can use that fingerprint to prove what data Xandeum was holding at a given moment in time — without trusting Xandeum, its team, or any third party. It is the first time a Solana-native infrastructure project has tied its trust model to Bitcoin. “Solana gives us the speed and programmability to…

Jessie A Ellis Apr 27, 2026 16:59 IREN (NASDAQ:IREN) transitions from Bitcoin mining to AI cloud services, aiming for $3.7B revenue with Microsoft partnership and GPU expansion. IREN Limited (NASDAQ: IREN) is undergoing a seismic shift in its business model, moving away from Bitcoin mining to focus on AI cloud infrastructure. According to Bernstein analysts, this pivot could generate $3.7 billion in annual revenue once fully implemented, with the company already securing a five-year agreement with Microsoft for AI workloads. The transition hinges on IREN’s $5.8 billion investment in GPUs and its ability to repurpose existing Bitcoin mining facilities in…

The emails passed domain authentication checks because they appeared to have been sent through Robinhood’s actual email infrastructure. Ripple’s CTO Emeritus David Schwartz posted a warning on X, telling users that a phishing campaign had sent fraudulent security alerts appearing to come from Robinhood’s own email infrastructure. Robinhood has since confirmed the incident, attributing it to an abuse of its account creation flow rather than any breach of its systems. What the Phishing Email Looked Like and How It Got Through According to Schwartz, the fake email, whose subject line was “Your most recent login to Robinhood,” claimed that there…

The global crypto market cap sits at $2.59T today, down 1.32% over the last 24 hours, and it’s a muted session across the board. Bitcoin itself is trading at $77,390, +0.49% on the day. Meanwhile, the Layer 2 sector continues to attract serious capital, particularly around chains that can solve real throughput problems rather than just rebrand existing ones. Solana is holding at $85.19, essentially flat on both the day (-1.41%) and the week (-0.06%). Mantle (MNT) is $0.64, down 2.43% on the day but up 3.28% over the week, a modest recovery that reflects continued appetite for L2 plays.…

Wyoming, United States, April 27th, 2026, Chainwire PoW to PoS to PoB: Nexus AiCOS v1.1 Defines “Proofs of Behavior” as the On-Chain Basel III Credit Standard for the AI Agent Civilization on Base Nexus AiCOS, the pioneering on-chain identity and credit primitive for the agentic economy, officially announces the release of Whitepaper v1.1 Axiom Edition. This definitive technical blueprint establishes Proofs of Behavior (PoB) as the arbiter of credit for autonomous entities, mapping the fundamental evolution of decentralized trust from Proof of Work (PoW) to Proof of Stake (PoS), and now to Proofs of Behavior (PoB). Moving beyond speculative hype and…

The Solana ecosystem has become the primary battleground for on-chain trading in 2026. With transaction speeds under 400 milliseconds and fees measured in fractions of a cent, Solana offers the infrastructure that high-frequency memecoin trading demands. But speed alone does not make a successful trader. The tools you use — specifically, the trading bot you choose — can be the difference between catching a 10x launch and watching it pump without you. Over a dozen Solana trading bots now compete for market share, each with different strengths, fee structures, and risk profiles. Choosing the wrong one costs money through higher…

Dr. Kamilah Stevenson is drawing a direct line between today’s macro backdrop and a potential breakout moment for XRP, arguing that the token’s fixed and shrinking supply profile could make it a standout performer in a period of elevated inflation and a constrained Federal Reserve.The wealth-focused YouTube show host frames the current environment as unusually favorable for scarce assets. With inflation still elevated and the Fed’s “hands tied,” she claims, assets that cannot be easily inflated tend to outperform “everything else that’s being inflated around them.”In that framework, XRP is presented less as a speculative altcoin and more as a…

The U.S. Commodity Futures Trading Commission sued New York on Friday in its latest action to shield what the agency has argued is its unassailable nationwide regulatory authority over prediction market firms.Earlier this week, New York sued Coinbase and Gemini, arguing that their prediction market contracts violated state gambling laws. And last year, the state had similarly targeted Kalshi, demanding it cease its sports wagering platform.The CFTC, in its role as the federal derivatives regulator, has staked out a position that the states have no business interfering with those firms. The agency’s suit in the U.S. District Court for the…

A researcher has made a small but notable step toward breaking the cryptography that secures Bitcoin, but the claim has already sparked pushback over how meaningful the result really is. Project Eleven said it awarded a 1 BTC “Q-Day Prize” to Giancarlo Lelli for deriving a private key from a public key using a quantum computer. We awarded the Q-Day Prize today to Giancarlo Lelli for breaking a 15-bit elliptic curve key on a publicly accessible quantum computer. They derived a private key from its public key using a variant of Shors across 32,767 candidates on cloud-accessible hardware. This is…
