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.

Trump to sign Thursday executive order approving TikTok U.S. deal

Trump to sign Thursday executive order approving TikTok U.S. deal

The post Trump to sign Thursday executive order approving TikTok U.S. deal appeared on BitcoinEthereumNews.com. President Donald Trump will sign an executive order on Thursday declaring that a deal to sell TikTok’s U.S. operations meets requirements of a 2024 law, a White House source said.  The deal would move TikTok’s U.S. operations to a consortium of American investors, including Oracle, and ensure compliance with the law that bans the platform unless its Chinese owner, ByteDance, is removed. Trump delays TikTok ban to finish U.S. sale President Donald Trump delayed banning TikTok in the United States because the platform has more than 170 million users in the United States. The ban would affect millions of people, businesses, and creators who use TikTok to watch videos, share content, and connect with people worldwide. The executive order that Trump will sign on Thursday might extend the pause for another 120 days. Doing so will allow the White House, investors, technology experts, and legal teams enough time to ensure every part of the deal works. According to the law, the president can decide what counts as a real “divestiture.” Trump can decide if the deal really separates TikTok’s U.S. operations from ByteDance’s control. This involves checking who owns the company, how much ByteDance will keep, how the recommendation algorithm works, how user data is stored, and who controls the app’s operations in the United States. Under the plan approved by President Trump, ByteDance might keep less than 20% of the new U.S. company. In contrast, a group of American investors, including Oracle and other major companies, will take control. American investors take control and secure TikTok The deal introduces major American business leaders and companies, including Oracle, Michael Dell of Dell Technologies, and members of the Murdoch family, who own media companies such as News Corp and Fox. These members will oversee the platform and make sure it operates…

Chainlink Proof of Reserve verifies ETP on BTC and ETH on Arbitrum

Chainlink Proof of Reserve verifies ETP on BTC and ETH on Arbitrum

The post Chainlink Proof of Reserve verifies ETP on BTC and ETH on Arbitrum appeared on BitcoinEthereumNews.com. Two physically backed ETPs on Bitcoin and Ethereum introduce an on-chain proof of reserve published on Arbitrum via Chainlink Proof of Reserve, as confirmed by Crypto Finance and documented by Chainlink and the related technical deep dive on the official blog. The data, public, cryptographic, and independently verifiable, allow investors and auditors to transparently verify the backing of the assets. The announcement, communicated on September 24, 2025, involved Crypto Finance (regulated custodian, part of the Deutsche Börse group), nxtAssets (issuer), and Chainlink (oracles). According to public data from Chainlink, the Proof of Reserve solution has verified over 17 billion dollars in reserves and supports more than 40 active feeds. By analyzing the public feeds available on data.chain.link and the recorded outputs on Arbitrum, it is possible to check timestamps and update history, providing concrete elements for auditability. Industry analysts observe that the adoption of PoR on layer-2 like Arbitrum facilitates scalability and on-chain writing costs, accelerating data availability for auditors and institutional investors. The on-chain update model allows for more continuous reserve monitoring compared to traditional end-of-day reports, thus offering a measurable level of transparency for investors and auditors without exposing sensitive addresses. In this context, data visibility is enhanced by automated attestation procedures. Activation: actors, products, and regulatory perimeter Parties involved: nxtAssets (issuer/manager ETP), Crypto Finance (regulated custodian and part of the Deutsche Börse group, Chainlink (oracles and Proof of Reserve). Products: two physically-backed ETPs on BTC and ETH, already operational. Data publication: the output of the Chainlink Runtime Environment (CRE) is written on Arbitrum. Regulation: Crypto Finance AG is supervised by FINMA; Crypto Finance (Deutschland) GmbH obtained the MiCAR license on January 25, 2025, as reported by Crypto Finance; custody is approved for SIX. Announcement date: September 24, 2025. ETP is the acronym for Exchange‑Traded Product, while NAV…

Flare Brings Non-Custodial XRP Into Decentralized Finance

Flare Brings Non-Custodial XRP Into Decentralized Finance

The post Flare Brings Non-Custodial XRP Into Decentralized Finance appeared on BitcoinEthereumNews.com. Fintech 25 September 2025 | 12:00 Flare’s native token, FLR, surged nearly 8% in the past day to trade near $0.03, reflecting investor enthusiasm after the network introduced FXRP – a new wrapped version of XRP designed for decentralized finance. With a market capitalization of around $1.9 billion, FLR is positioning itself as a gateway for assets like XRP to enter DeFi at scale. At its core, FXRP is part of Flare’s FAssets system, which transforms tokens without native smart contracts into onchain, overcollateralized assets. For XRP holders, that means the ability to mint a one-to-one version of their coins that can be deployed into lending markets, liquidity pools, or other DeFi applications. Unlike earlier custodial wrappers that struggled to gain adoption, FXRP uses Flare’s own oracle and data connectors to keep the process decentralized and verifiable. The rollout is starting cautiously, with just five million FXRP available during the first week, though the ceiling will expand over time. Holders can mint directly through Flare’s independent agents or acquire FXRP on decentralized exchanges such as SparkDEX, BlazeSwap, and Enosys. Popular wallets like Luminite and Oxen Flow have already integrated support for minting, swapping, and bridging. Flare is also dangling incentives to bring liquidity onto the network. Rewards in rFLR – its native emissions token – will be distributed to FXRP trading pools, with some early pairs targeting aggressive yields. Borrowing against FXRP is being rolled out as well, providing more utility for the wrapped asset. Security has been a central talking point. The FAssets system has been audited by Zellic and Coinspect, with additional bug bounties and constant monitoring from Hypernative in place. These safeguards are designed to reassure users that the infrastructure can handle large-scale activity. The launch represents a bigger shift for XRP, which has long sat outside…

What will the Q3 earnings season show?

What will the Q3 earnings season show?

The post What will the Q3 earnings season show? appeared on BitcoinEthereumNews.com. Here are the key points: For 2025 Q3, total S&P 500 index earnings are expected to be up +5.2% from the same period last year on +6.0% higher revenues. The positive revisions trend makes the overall setup for the Q3 earnings season favorable, but it raises the odds of actual results coming up short of expectations. In other words, it is reasonable to worry whether expectations for the period are too high, particularly for the Tech and Finance sectors.  Excluding the Tech sector contribution, Q3 earnings for the rest of the S&P 500 index would be up only +2.2% (vs. +5.2% otherwise). For the Magnificent 7 group, Q3 earnings are expected to be up +12.1% from the same period last year on +14.6% higher revenues, which would follow the group’s +26.4% earnings growth on +15.5% revenue growth in the preceding period. Are Q3 earnings expectations too high? As we have consistently highlighted in recent weeks, the overall revisions trend remains positive, with estimates for the back half of the year steadily going up. For 2025 Q3, the expectation is for earnings growth of +5.2% on +6.0% revenue gains. We have consistently shown in this space how Q3 estimates have steadily increased since the quarter began. A comparable trend has been at play with respect to estimates for the last quarter of the year, when S&P 500 earnings are expected to increase by +7.1% on +6.7% higher revenues. The chart below shows how Q4 estimates have evolved over the last couple of months. Image Source: Zacks Investment Research Some of the same sectors that have been enjoying a favorable revisions trend for Q3 are in play for Q4 as well, particularly the Tech, Finance, and Energy sectors. JPMorgan (JPM – Free Report) and Wells Fargo (WFC – Free Report) will kick…
