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.

Sports Betting Pushes Kalshi and Polymarket Volumes to All-Time Highs

Sports Betting Pushes Kalshi and Polymarket Volumes to All-Time Highs

The post Sports Betting Pushes Kalshi and Polymarket Volumes to All-Time Highs appeared on BitcoinEthereumNews.com. Both leading prediction markets combined did more volume in October than Polymarket did in its first four years. October marked the prediction market sector’s best month yet, with leading platforms Kalshi and Polymarket processing a cumulative $7.4 billion in volume, well above their previous record in November 2024, when they processed a total of $4 billion driven by the U.S. Presidential election. While election markets —primarily the NYC Mayoral Election —are still generating hundreds of millions in volume, other niches, such as sports betting, are boosting volume metrics further. In October, Kalshi processed $4.4 billion, and Polymarket recorded $3 billion in volume, new all-time highs for both venues. Kalshi Volumes – Kalshi Sports markets on Kalshi in particular have exploded, with the offchain prediction market processing more than $1.1 billion in sports betting volume between Oct. 20 and Oct. 27, compared to just $51 million in its politics category. Meanwhile, Polymarket recorded $357 million in sports betting volume over the same period. On Oct. 22, legacy sports betting platform DraftKings also announced its acquisition of the Railbird prediction market, which will use Polymarket Clearing as its official clearinghouse. The surge in volume could be catalyzed by developments in both U.S. tax law and airdrop speculation. Under the One Big Beautiful Bill passed by the Trump administration in July, 2026 will mark the first year in which sports gamblers can only write off 90% of their gambling losses, as opposed to 100% currently. While the tax rules surrounding prediction markets are a little vague, sportsbooks and high-volume gamblers may be preparing for a world where prediction market sports gambling offers significant tax benefits compared to traditional bookies. There is also increased speculation around future token airdrops from Polymarket and Kalshi. Polymarket, a decentralized onchain prediction market, naturally has room in its…

Some blockchains are meant to do one thing

Some blockchains are meant to do one thing

The post Some blockchains are meant to do one thing appeared on BitcoinEthereumNews.com. Disclosure: The views and opinions expressed here belong solely to the author and do not represent the views and opinions of crypto.news’ editorial. In every industry, specialization eventually outpaces generalization. As the complexity of systems increases, the tools that thrive are not the ones that attempt to do everything at once, but the ones designed to do one thing exceptionally well. Notably, technology has always followed this path. Cloud computing is split into storage, compute, and databases, chip design is branched into CPUs, GPUs, and TPUs, and finance came to rely on clearinghouses and custodians as dedicated infrastructure. Blockchain is not an exception. Summary As blockchain ecosystems mature, purpose-built networks (data availability, stablecoins, tokenized assets) outperform general-purpose chains, with proof verification identified as the next critical domain. High-volume proof generation from zkVMs, rollups, and zkML systems strains Ethereum’s L1 gas system, making verification costly, unpredictable, and inefficient for large-scale applications. Specialized layers reduce cost and latency, support new proof types, and enable “verify once, use everywhere” across zkVMs, identity protocols, gaming, AI, and cross-chain applications, unlocking modular scalability and efficiency. Throughout cycles, the blockchain ecosystem has begun to fragment into purpose-built networks for data availability, stablecoins, tokenized assets, and settlement layers optimized for speed and security. Tracing this path, it becomes clear that proof verification is the next domain ready to follow this trajectory. It’s a layer that’s long overdue for its own specialized layer. Verification is the choke point Zero-knowledge virtual machines, or zkVMs, and cryptographic applications are now producing more proofs than ever before. Rollups, privacy-preserving apps, and zkML systems are moving into production, each generating vast volumes of proofs that need to be checked. The demand is only accelerating, but the infrastructure for verifying proofs hasn’t kept pace. On Ethereum (ETH), a single proof verification consumes around…

Warren Buffett may have again cut Berkshire’s stake in Apple in Q3

Warren Buffett may have again cut Berkshire’s stake in Apple in Q3

The post Warren Buffett may have again cut Berkshire’s stake in Apple in Q3 appeared on BitcoinEthereumNews.com. Warren Buffett speaks during the Berkshire Hathaway Annual Shareholders Meeting in Omaha, Nebraska on May 3, 2025. CNBC Warren Buffett’s Berkshire Hathaway may have quietly trimmed its massive Apple stake again in the third quarter, a new regulatory filing suggests. In its latest quarterly report, Berkshire said the cost basis of its consumer products equity holdings fell by roughly $1.2 billion from the prior quarter. That category is dominated by the giant conglomerate’s Apple position, implying the decline likely reflects additional sales of Apple shares. Apple’s stock jumped more than 24% in the third quarter, a rally that would have offered Buffett an attractive opportunity to take profits. Stock Chart IconStock chart icon Apple year to date Buffett went on a head-turning selling spree in Apple in 2024, slashing two-thirds of the shares Berkshire held in a surprising move for the famously long-term-focused investor. Berkshire also trimmed its Apple stake in the second quarter of this year. The iPhone maker was still Berkshire’s largest holding at the end of June, when it controlled 280 million shares worth $57 billion. Investors will get more clarity about the exact size of Berkshire’s Apple position when it releases its detailed 13F filing it makes to the Securities and Exchange Commission later this month. That will disclose any changes to individual stock holdings through September 30. Buffett had previously hinted that selling down the Apple stake was for tax reasons, but others speculated that the size of the sales suggested the so-called Oracle of Omaha was also concerned about Apple’s high valuation. Some thought it was also part of portfolio management, as the Apple stake had grown so big that at one time it accounted for more than half of Berkshire’s investment portfolio. Berkshire has been a net seller of stocks for 12 straight quarters,…

FTSE Russell Brings Its Indices Onchain Through Chainlink’s DataLink – Turning Point for Institutional Finance?

FTSE Russell Brings Its Indices Onchain Through Chainlink’s DataLink – Turning Point for Institutional Finance?

Chainlink has announced a collaboration with FTSE Russell to bring the index provider’s benchmarks on-chain via DataLink, Chainlink’s institutional-grade data publishing service. In a press release shared with CryptoNews, the firm explains that this move marks the first time FTSE Russell’s data—including the Russell 1000, Russell 2000, Russell 3000, and FTSE 100 indexes, alongside WMR FX benchmarks and FTSE Digital Asset Indices—will be available directly on blockchain networks. With over $18 trillion in assets under management benchmarked against its indices, FTSE Russell’s entry into the blockchain space represents a major step in bridging traditional finance and decentralized ecosystems. The data will now be accessible across more than 50 public and private blockchains to 2,000+ Chainlink ecosystem applications, opening the door to new tokenized financial products. Accelerating Institutional Adoption of Tokenized Assets FTSE Russell’s decision to publish its index data on-chain reflects the growing demand among financial institutions for trusted, regulated data sources in digital markets. By using Chainlink’s oracle infrastructure, institutions and developers can build tokenized assets, ETFs, and next-generation financial products. “We’re excited to bring our index data on-chain using Chainlink’s institutional-grade infrastructure,” said Fiona Bassett, CEO at FTSE Russell, an LSEG business. “This marks a major step in enabling innovation around tokenized assets and next-generation financial products. DataLink allows FTSE Russell to securely distribute trusted benchmarks across global on-chain markets,” adds Bassett. DataLink: A Bridge Between Traditional and Decentralized Markets Chainlink’s DataLink serves as a turnkey solution, allowing data providers to publish information directly onto blockchains without building or maintaining new infrastructure. It uses Chainlink’s oracle technology, which has allowed over $25 trillion in transaction value and actively secures nearly $100 billion in DeFi total value locked (TVL). The service ensures that data from established providers like FTSE Russell is authenticated, tamper-proof, and accessible 24/7, allowing DeFi protocols to reference the same high-quality data that powers traditional financial systems. A Defining Moment for On-chain Finance Chainlink co-founder Sergey Nazarov described the collaboration as a “landmark moment” for both industries. “FTSE Russell bringing its trusted benchmarks to blockchains via Chainlink is a critical step toward enabling the next generation of data-driven financial products and tokenized assets,” Nazarov said. With this integration, blockchain developers and financial institutions can verify, reference, and build with FTSE Russell’s data across multiple blockchains, setting the stage for broader adoption of regulated, data-backed financial instruments in decentralized markets. U.S. Commerce Dept Partners with Chainlink to Bring Data On-chain In August, the United States Department of Commerce (DOC) said it has teamed up with Chainlink to bring macroeconomic data from the Bureau of Economic Analysis (BEA) on-chain. Chainlink shared that through its oracle infrastructure, key indicators such as Real Gross Domestic Product (GDP), the Personal Consumption Expenditures (PCE) Price Index, and Real Final Sales to Private Domestic Purchasers are now available across ten blockchain systems. This move also marked the first time U.S. government economic data has been published on-chain in a verifiable way. According to the firm, developers can immediately integrate the Chainlink Data Feeds into decentralized applications (dApps), unlocking use cases such as automated trading strategies, composable tokenized assets, prediction markets, and risk management tools for DeFi protocols. Chainlink Price Action Chainlink’s native token, LINK, fell sharply over the past 24 hours, sliding 11.22% to $15.29 at the time of writing, according to data from CryptoNews. The LINK/USD pair, trading on Coinbase, recorded a daily high of $17.65 and a low of $14.54, closing at $15.31—a drop of nearly 13% on the day. Trading volume surged to 1.95 million LINK, indicating strong sell-side activity. Chainlink currently ranks #20 by market capitalization, with a total supply of 1 billion tokens

$116M in Crypto Assets Gone – Balancer Suffers One of DeFi’s Largest Exploits

$116M in Crypto Assets Gone – Balancer Suffers One of DeFi’s Largest Exploits

Over $116 million in crypto assets have been drained from Balancer Protocol, marking one of the most severe decentralized finance (DeFi) exploits of 2025. At approximately 9:12 AM on Monday, blockchain analytics firm Lookonchain first raised the alarm, reporting that Balancer had been exploited for $70.6 million in crypto assets. Initial data revealed that the attacker siphoned off 6,587 WETH ($24.46 million), 6,851 osETH ($26.86 million), and 4,260 wstETH (~$19.27 million) across multiple blockchains. Balancer $116M DeFi Exploit Unfolds Within just thirty minutes, Lookonchain updated that the attack was still ongoing, with total stolen funds exceeding $116 million. The scale and precision of the exploit suggest a highly coordinated and technically sophisticated operation spanning several DeFi ecosystems. As of press time, on-chain data shows the hacker’s DeBank portfolio holding around $95 million, while roughly $21 million has been distributed to various wallets, likely an early move toward obfuscating and liquidating the stolen assets.Source: DeBank The exploit has also triggered a ripple effect across Balancer-forked projects, as many associated protocols reported security breaches or precautionary withdrawals. Panic withdrawals began soon after news of the attack broke, most notably from a whale wallet (0x0090) that had been dormant for three years but suddenly withdrew $6.5 million from Balancer pools. Major DeFi Protocols Respond Major Ethereum-based protocols have been quick to respond. Lido, a leading liquid staking platform, confirmed that certain Balancer V2 pools were impacted but clarified that Lido’s core protocol and user funds remain safe. In an official statement, Lido noted: “Out of an abundance of caution, the Veda team — curators of Lido GGV — has withdrawn its unaffected Balancer position.” Meanwhile, Aave, another top DeFi lending protocol, emphasized that it remains completely unaffected. Aave explained that its Aave/stETH stkBPT pool uses a custom version of Balancer V2 that operates independently of Balancer’s vulnerable components. “The Aave protocol has no dependencies over Balancer V2 and is unaffected to the best of our knowledge,” the team stated. Unclear Root Cause and Ongoing Investigation Balancer developers have acknowledged the exploit but have not revealed the root cause or the extent of the loss. However, early signs point to a complex cross-chain exploit vector that may have targeted the protocol’s unique liquidity architecture. Moreover, today’s exploit is not the first time the Balancer protocol has faced attacks and drains from its pools. In August 2023, the protocol suffered a $2 million drain associated with a code vulnerability, and then the following month, over $900,000 was drained again across its V2 pool. Just like the recent exploit, the vulnerable assets were spread across various networks, including Ethereum, Polygon, Arbitrum, Optimism, Avalanche, Gnosis, Fantom, and zkEVM. Growing DeFi Security Concerns Another noticeable concern about the recent crypto exploit is how it’s now spreading across every major chain aside from Ethereum. On September 8, Nemo Protocol, a decentralized finance (DeFi) yield platform operating on the Sui blockchain, fell victim to a cyberattack that resulted in $2.4 million in losses just ahead of its scheduled maintenance window. On the same day, Swiss crypto platform SwissBorg lost $41.5 million worth of Solana (SOL) tokens after hackers compromised partner API provider Kiln. Similarly, in May, Cryptonews reported that Cetus Protocol, a decentralized exchange built on the Sui blockchain, fell victim to an exploit that siphoned off more than $200 million in crypto assets. PeckShield’s latest report reveals that crypto hacks caused $127.06 million in losses in September 2025 alone, noting the continued risk of large-scale attacks on decentralized finance (DeFi) and blockchain platforms. In just the first half of 2025, crypto exploits reached $2.1 billion, nearly matching all of 2024’s total losses. Why Crypto Hacks Keep Happening When Cryptonews spoke with Mitchell Amador, founder and CEO of Immunefi, in August, he revealed that most crypto hacks happen for three major reasons, which are: Static audits: Enterprises rely on one-time checks, missing post-launch flaws in evolving smart contracts. Ignoring incentives: They underestimate Web3’s open-ledger attack appeal, needing bounties to outbid black hats. No Web3 expertise: Many teams lack prior blockchain knowledge, missing composability or oracle risks
