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.

Vitalik Buterin Reiterates Blockchain Security Amid Validator Risks

Vitalik Buterin Reiterates Blockchain Security Amid Validator Risks

The post Vitalik Buterin Reiterates Blockchain Security Amid Validator Risks appeared on BitcoinEthereumNews.com. Key Points: Vitalik Buterin alerts to risks of off-chain validator reliance. 51% validator majority cannot execute asset theft. Developers and community urged to enhance on-chain security. On October 26, Ethereum co-founder Vitalik Buterin emphasized on the X platform blockchain’s resilience against 51% attacks affecting consensus but warned about off-chain trust risks. Buterin’s warning highlights potential vulnerabilities in validator-based systems and is crucial for protocols relying on off-chain data, underscoring the need for reinforced security measures. Ethereum’s Market Trends and Expert Cautions As of October 26, 2025, Ethereum (ETH) trades at $3,934.51, reflecting a 4.85% rise over the past 24 hours, per CoinMarketCap. Its market cap stands at $474.89 billion with a dominion of 12.63%. Despite these figures, Ethereum has experienced a 13.75% decrease in the past 60 days. According to the Coincu research team, the potential increases in off-chain trust could elevate exposure to systemic risks. They suggest a reevaluation of reliance on validator-driven oracles, with an emphasis on enhancing on-chain data robustness. Ethereum’s market trends show that such developments could impact price stability and investor confidence significantly. “A key feature of blockchains is that even a 51% attack cannot render invalid blocks valid. This means that even if 51% of validators collude (or suffer a software vulnerability attack), users’ assets cannot be stolen. However, if you start trusting your validator set to do other things outside the blockchain’s control (off-chain), then this feature becomes invalid—at that point, 51% of validators could collude and give incorrect answers, and you would have no recourse.” — Vitalik Buterin, Co-founder, Ethereum Market Data and Insights Did you know? Historically, off-chain oracle failures have led to significant financial losses, notably in the 2020 bZx and Compound incidents, underscoring the risks Buterin warns against. Ethereum (ETH) trades at $3,934.51, reflecting a 4.85% rise over the…

Near’s emission vote misses threshold, triggering governance crisis

Near’s emission vote misses threshold, triggering governance crisis

The post Near’s emission vote misses threshold, triggering governance crisis appeared on BitcoinEthereumNews.com. NEAR Protocol, the Layer 1 blockchain, is facing a major disagreement amongst its community members over inflation reduction. The community is divided about how many new NEAR tokens should be printed every year. For months, people in the community have been talking about cutting the network’s inflation rate from 5% to 2.5%. The goal was to balance NEAR token emissions with generated fees. Near is operating at a loss At the moment, the NEAR Protocol pays around $140 million worth of tokens annually to the network validators. But this amount does not make sense compared to NEAR’s total value locked (TVL) and generated revenue. The protocol has around $162 million in total value locked (TVL). To make things worse, NEAR Protocol has a lifetime revenue of only $17 million since its inception in 2020. The protocol generated $259,116 in revenue in the last 30 days based on DeFiLlama data. Securing the network is expensive compared to the generated revenue. That’s why the community is trying to fix this issue. They voted on reducing the inflation rate from 5% to 2.5%. More than 50% of voters said yes, but that’s not enough. The voting result should hit a supermajority, which is 66.67% or more. This is part of the protocol’s required rules to count the proposal as an official change. The vote has technically failed to reduce NEAR’s inflation. Devs might cut NEAR emission Some of NEAR’s core developers are hinting that they might still include the emission cut in the next software update anyway. A validator group called Chorus One called that out, saying it’s basically breaking the rules. They wrote on X, “We believe this sets a dangerous precedent and undermines the integrity of NEAR. It gives the impression that decisions can be unilaterally enforced by the core team.”…

Validators receive $140 million yearly in rewards, far exceeding the $17 million lifetime revenue, sparking governance tensions. NEAR Protocol operates at a financial loss, with validator rewards outpacing revenue generation. Community vote for inflation reduction reached over 50% approval but fell short of the required 66.67% supermajority. Core developers may implement the cut unilaterally, raising concerns from validators like Chorus One about governance integrity, based on protocol data showing $162 million TVL and $259,116 in recent monthly revenue.

Trump’s AI-fueled boom hides strain on small businesses as tariffs and costs rise

Trump’s AI-fueled boom hides strain on small businesses as tariffs and costs rise

The post Trump’s AI-fueled boom hides strain on small businesses as tariffs and costs rise appeared on BitcoinEthereumNews.com. The $350 billion AI splurge by America’s biggest tech companies is giving Donald Trump’s economy a shiny look, but beneath the surface, small businesses and workers are dealing with higher prices, weaker spending, and fewer jobs. The boom that started in Silicon Valley is helping Wall Street hit record highs, yet in places like Birmingham, Alabama, flower shop owners like Cameron Pappas are cutting stems just to keep customers from walking away. The story, reported by CNBC, shows a country where trillion-dollar tech firms are fueling growth numbers while the rest of the economy tries to breathe. Cameron’s Norton’s Florist, a family business founded in 1921, made $4 million last year selling flowers and gifts. But with Trump’s sweeping tariffs raising import costs, Cameron said he’s been forced to “keep an eagle eye on all of our costs.” He explained that instead of raising prices, he’s trimming his flower arrangements. “If a bouquet has 25 stems in it, if you reduce that by three to four stems, then you’re able to keep the price the same,” he said. “It’s really forced us to focus on that and to make sure that we’re pricing things the best that we possibly can.” AI spending lifts the markets but not everyone else The AI mania has become a statistical miracle. A JPMorgan Chase report showed that in the first half of 2025, AI-related investments alone added 1.1% to U.S. GDP growth, beating out consumer spending as the country’s main growth driver. The Commerce Department said GDP grew 3.8% in the second quarter after falling 0.5% in the first. Yet in real terms, manufacturing has been shrinking for seven straight months, and construction is flat because of high interest rates and the rising cost of materials. Cushman & Wakefield expects total construction costs to…

Trading-Volume Rumors Trigger User Sprint

Trading-Volume Rumors Trigger User Sprint

The post Trading-Volume Rumors Trigger User Sprint appeared on BitcoinEthereumNews.com. Key Takeaways: Polymarket CMO Matthew Modabber says a $POLY token and airdrop are coming. Community expects airdrop eligibility to factor trading volume, rewarding active users. Team emphasis on a U.S. app rollout before the token goes live, aiming for utility over hype. Polymarket, the crypto-native prediction market, is entering a new phase: a native POLY token with an airdrop is officially on the roadmap. While details are thin, the team is pushing for real utility and a measured rollout, not a rush to market with ongoing chatter that user trading volume could influence allocations. Read More: Chainlink Partners with Polymarket to Accelerate $100B Network of Oracle Ecosystem What’s Official vs. What’s Rumor Polymarket’s CMO Matthew Modabber has publicly confirmed two facts: there will be a POLY token, and there will be an airdrop. The company has not published dates, allocation formulas, or claim mechanics. What’s still unconfirmed but widely discussed: an eligibility model tied to trading activity. The community posts and trader threads indicate that the bigger the on-platform volume it could get the bigger airdrop shares might be. This is speculative until Polymarket announces official criteria. Why $POLY Matters for a Prediction Market Incentives that are anchored on a native token can reinforce market quality in case the design is tight and the applications are transparent. In the case of prediction markets, the common range of token utility is: Fee offsets or rebates: Eliminating taker/maker costs to increase deepening liquidity. Staking/guarantees: Converting market creators, resolvers, or participants of a dispute. Governance inputs: Allowing interested users to affect listings, fee curves, or resolution policies. Liquidity programs: Direct rewards for providing two-sided depth on popular markets. Polymarket has signaled a focus on long-term utility rather than a quick distribution. That choice generally improves outcome quality (better spreads, fewer abandoned markets) and…
