Oracle

Oracles are essential infrastructure components that feed real-time, off-chain data (such as price feeds, weather, or sports results) into blockchain smart contracts. Without decentralized oracles like Chainlink and Pyth, DeFi could not function. In 2026, oracles have evolved to support verifiable randomness and cross-chain data synchronization. This tag covers the technical evolution of data availability, tamper-proof price feeds, and the critical role oracles play in ensuring the deterministic execution of complex decentralized applications.

BitFrac Makes Bitcoin Mining Accessible Now

BitFrac Makes Bitcoin Mining Accessible Now

The post BitFrac Makes Bitcoin Mining Accessible Now appeared on BitcoinEthereumNews.com. Real-world asset (RWA) tokenization is fast becoming one of the biggest stories in blockchain. Industry analysts now foresee the market exceeding $16 trillion by 2030, and possibly even more in the years that follow. Yet, one area of this movement, Bitcoin mining infrastructure, hasn’t received nearly as much attention. That’s where BitFrac steps in. BitFrac is taking a fresh approach by combining RWA tokenization with Bitcoin mining, giving everyday people a way to own a piece of real mining equipment. In other words, it’s opening the door to a trillion-dollar industry that used to be reserved for industrial players. The $16 Trillion Tokenization Wave The concept behind tokenization isn’t complicated, but transforming. By turning tangible assets like property, gold, or even Bitcoin miners into blockchain tokens, investors can buy, sell, or hold pieces of high-value assets without having to commit millions of dollars upfront. A Boston Consulting Group report projects that tokenized assets could be worth around $16 trillion by 2030. Standard Chartered goes even further, suggesting that the number could climb to $30 trillion by 2034. The reason? Investors are hungry for easier access, transparency, and liquidity. And right in the middle of this movement is BitFrac, which is applying these principles to mining, one of crypto’s oldest and most profitable sectors. Tokenization of global illiquid assets estimated to be a $16 Trillion business opportunity by 2030 (Source: ADDX) Fractional Mining Ownership, the BitFrac Way So, how does BitFrac actually work? Instead of buying and maintaining an entire mining rig, which can cost thousands of dollars, investors can buy BitFrac Tokens ($BFT). Each token represents a fractional share of real, operational mining hardware. Here’s the idea in simple terms: You can start small, even a $100 stake in $BFT is enough to get involved. Each token links directly to…

Moonwell Protocol Loses $1M in Oracle Manipulation Exploit

Moonwell Protocol Loses $1M in Oracle Manipulation Exploit

The post Moonwell Protocol Loses $1M in Oracle Manipulation Exploit appeared on BitcoinEthereumNews.com. BlockSec Phalcon detects suspicious transactions targeting Moonwell contracts. Exploit stems from an incorrectly updated price feed from an off-chain oracle system. MEV bot possibly exploited an oracle issue, resulting in losses exceeding $1 million. On-chain threat detection platform BlockSec Phalcon has identified a series of suspicious transactions targeting Moonwell’s smart contracts. The platform issued an alert regarding the activity on Base and Optimism networks that resulted in losses exceeding $1 million. BlockSec’s analysis points to an issue with the token price feed for rsETH/ETH from the off-chain oracle. The exploit appears to have been carried out, possibly by a MEV bot that took advantage of incorrectly updated price data used by the protocol. ALERT! Our system detected a series of suspicious transactions targeting @MoonwellDeFi’s smart contracts on #Base and #Optimism. Our analysis indicates an issue with the token price (rsETH / ETH) feed from the off-chain oracle, which was exploited — possibly by a MEV bot —… pic.twitter.com/cNJFHI3xn3 — BlockSec Phalcon (@Phalcon_xyz) November 4, 2025 The attack exploited a vulnerability in how the protocol received and processed price information from external data sources. When the rsETH/ETH price feed failed to update correctly, the discrepancy between actual market prices and protocol prices created an arbitrage opportunity. MEV bots typically scan blockchain networks for profitable opportunities, including price discrepancies across protocols. In this case, the bot appears to have identified the oracle malfunction and executed transactions to extract value before the issue could be corrected. BlockSec noted that no direct contact method was available to reach the project team immediately. The platform requested that anyone with questions or relevant information reach out directly to them for coordination. The Moonwell incident follows a larger exploit targeting the Balancer protocol on November 3, 2025. That attack resulted in losses exceeding $70 million, making it…

Crypto mining meets AI – Cipher ‘ahead of the curve’ with $5.5B AWS deal

Crypto mining meets AI – Cipher ‘ahead of the curve’ with $5.5B AWS deal

The post Crypto mining meets AI – Cipher ‘ahead of the curve’ with $5.5B AWS deal appeared on BitcoinEthereumNews.com. Key Takeaways How much capacity will Cipher deliver under the AWS agreement? The company will deliver 300 megawatts of capacity, with both air and liquid cooling systems, starting in July 2026. What other major project did Cipher announce? Cipher unveiled a joint venture to develop a 1-gigawatt (GW) site in West Texas, named “Colchis.” Cipher Mining Inc. has unveiled a game-changing move in its latest Q3 2025 financial report, and that is a $5.5 billion, 15-year lease deal with Amazon Web Services (AWS) to supply high-performance infrastructure for AI workloads. It goes to show how Cipher Mining is rapidly expanding beyond Bitcoin [BTC] mining, positioning itself as a key infrastructure player in AI and high-performance computing (HPC). Cipher Mining’s AI deal with AWS Under the deal, Cipher will deliver 300 megawatts of capacity, equipped with both air and liquid cooling systems, in two phases beginning July 2026 and concluding by year-end. That said, the rent payments under the agreement are set to start in August 2026. Needless to say, Tyler Page, Cipher’s CEO, didn’t shy away from expressing himself when he noted,  “The third quarter was truly transformative for Cipher. We executed a pivotal transaction with Fluidstack and Google, which firmly established our credibility in the HPC space. We are now following that transaction with another major step forward by signing our first direct lease with a Tier 1 hyperscaler.” Cipher’s joint venture in West Texas Alongside its AWS partnership, the company also announced a joint venture to develop a 1-gigawatt (GW) site in West Texas, called “Colchis.” In this partnership, Cipher will fund most of the project, securing around 95% equity ownership. The 620-acre Colchis site includes a 1-GW Direct Connect Agreement with American Electric Power (AEP), which will build a dual interconnection facility targeting energization in 2028. AEP…

Palantir drops 6% after Michael Burry reveals short position and valuation concerns

Palantir drops 6% after Michael Burry reveals short position and valuation concerns

Palantir’s stock plunged 6% on Tuesday, and it came even after the company posted strong earnings, raised its full-year guidance, and crossed $1 billion in revenue for the second quarter in a row. But Wall Street didn’t care very much, and not for very long either. What actually set the fire was Mr. Michael Burry (yes, the same guy from “The Big Short”) who just revealed he’s betting against Palantir. That sent shockwaves through the AI crowd and added fuel to fears that this stock might be flying too close to the sun. CEO Alex Karp didn’t sit quietly. He went on CNBC and absolutely lost it, saying short sellers are engaged in “market manipulation.” He said the trades were “super triggering” and accused them of “shorting one of the great businesses of the world.” He told CNBC, “We delivered the best results everyone, anyone’s ever seen.” But the market clearly disagreed. Because right after his comments, shares continued to slide anyway. Wall Street questions Palantir’s sky-high valuation The stock fall overshadowed Palantir’s numbers. They beat both revenue and earnings expectations, lifted guidance, and still got punished. Why? Expectations were already sky-high. Goldman Sachs’ Gabriela Borges reminded clients that the company had already crushed revenue last quarter by 7%, and the stock had soared 175% year-to-date. So basically, beating the numbers wasn’t enough anymore. Investors wanted fireworks, and they got… an angry CEO and a short position from Burry. The main issue is the valuation. Palantir trades at a forward price-to-earnings (P/E) ratio of 254. To compare, Nvidia, which is the most valuable chipmaker on Earth, trades at just 35. Even Oracle has a forward P/E of 35, and AMD sits at 149. So yeah, Wall Street thinks Palantir’s premium is insane. And unless the company keeps raising the bar, that multiple starts looking more and more ridiculous. Brent Thill at Jefferies said they still like Palantir but think better AI software bets exist, pointing to Microsoft and Snowflake as stronger picks. Mizuho said the risk-reward was becoming a “big challenge.” Over at D.A. Davidson, Gil Luria kept a neutral rating, saying Palantir is “raising the bar even higher.” Analysts at RBC didn’t sound impressed either, warning that while Palantir’s AIP platform is still being rolled out, growth is mostly limited to U.S. enterprise customers and early AI spending cycles. Market selloff hits Palantir and other AI names Palantir wasn’t the only one bleeding. The broader market also slumped Tuesday. The S&P 500 fell 0.9%, the Nasdaq lost 1.5%, and the Dow dropped 193 points. AI stocks led the drop. Oracle slid 2%, AMD dropped over 1%, and even giants like Amazon and Nvidia pulled back. The AI trade that’s been lifting the whole market just hit a wall. The S&P’s forward P/E ratio is now over 23, close to levels last seen in 2000, right before the dot-com crash. Anthony Saglimbene from Ameriprise told CNBC, “We haven’t really seen any major corrections or any real pressure on stocks since April.” He said the market needs a breather. With all the capital expenditures being pumped into AI, he questioned if the earnings growth can really keep up. Top Wall Street execs added to the panic. Goldman Sachs CEO David Solomon warned that a 10% to 20% drop in stocks is likely over the next 12 to 24 months. Morgan Stanley’s CEO Ted Pick said 10% to 15% drawdowns should be expected and aren’t even caused by big macro problems, they just happen. Even before Tuesday, markets were shaky. On Monday, the S&P 500 and Nasdaq rose, but the Dow dropped over 200 points. And though the S&P is still close to record highs, it even closed above 6,800 last month, traders are clearly nervous now.

Chainlink oracle glitch costs Moonwell $1M as DeFi suffers another exploit

Chainlink oracle glitch costs Moonwell $1M as DeFi suffers another exploit

The post Chainlink oracle glitch costs Moonwell $1M as DeFi suffers another exploit appeared on BitcoinEthereumNews.com. Key Takeaways What caused the Moonwell exploit? A Chainlink oracle price feed malfunction incorrectly valued 0.02 wrstETH (worth pennies) at millions, allowing an attacker to drain funds before the protocol could respond. How does this relate to other recent DeFi hacks? Moonwell’s loss came just 24 hours after Balancer’s $128M exploit and marks Moonwell’s fourth major hack in three years. DeFi suffered its worst start to a month in a long time as two major protocols lost $129 million in 48 hours.  A Chainlink oracle malfunction enabled a $1 million Moonwell exploit on 4 November, just one day after hackers drained $128 million from Balancer across six blockchains. The Chainlink oracle exploit An attacker exploited Moonwell’s lending protocol on Base using a sophisticated oracle manipulation attack. The hacker flashloaned approximately 0.02 wrstETH, worth mere pennies, and deposited it as collateral. However, a Chainlink oracle price feed temporarily malfunctioned, valuing this tiny collateral at $5.8 million. The protocol accepted the inflated valuation. The attacker immediately borrowed over 20 wstETH against the artificially valued collateral. Source: CertiK The exploit was repeated seven times within three hours, and each cycle netted approximately 24.5-24.9 ETH. The attacker executed everything within single blocks, avoiding liquidation mechanisms, and made a total profit of 292 ETH [around $1.01 million]. CertiK detected the exploit and confirmed that the oracle pricing error enabled the attack. The incident highlights the risks of infrastructure dependency in DeFi lending protocols, although Chainlink’s core oracle network remained secure throughout. TVL crashes, token plummets Analysis of DefiLlama data revealed that Moonwell’s Total Value Locked [TVL] collapsed from $268 million to $213 million, a $55 million exodus in just hours.  Source: DefiLlama Additionally, the WELL token declined by over 12% to trade at approximately $0.012, while the broader cryptocurrency market decreased by more than 1%.…
